The cancer stem cell theory suggests that tumors grow like normal tissues of the body, with stem cells at the starting point of an organized system that produces new cells to make a tissue grow. According to this idea, tumors contain:
Cancer stem cells that divide and feed tumour growth. These cells can self-renew (copy themselves) extensively, and also produce more mature cells called transit amplifying cells-...

Alzheimer’s disease is the most common form of dementia in the elderly, which accounts up to 80 % of all cases.
•Clinical manifestation of the disease includes cognitive impairments such as attention deficit, spatial disorientation, speech disorders, and progressive loss of memory.
•In the late stage of Alzheimer's, people generally lose the ability to communicate coherently, experience a decline in physical abilities and require total assistance with personal care.
•Those with Alzheimer's live an average of eight years after their symptoms become noticeable to others, but survival can range from four to 20 years, depending on age and other health conditions.--

Dengue represents one of the most serious life-threatening vector-borne infectious diseases that afflicts approximately 50 million people across the globe annually. Whilst symptomatic infections are frequently reported, asymptomatic dengue remains largely unnoticed. Therefore, we sought to investigate the immune correlates conferring protection to individuals that remain clinically asymptomatic.

Cohort
Background: With its elusive pathogenesis, dengue imposes serious healthcare, economic and social burden on endemic countries. This study describes the clinical and immunological parameters of a dengue cohort in a Malaysian city, the first
according to the WHO 2009 dengue classification. Methodology and Findings: This longitudinal descriptive study was conducted in two Malaysian hospitals where patients
aged 14 and above with clinical symptoms suggestive of dengue were recruited with informed consent. Among the 504 participants, 9.3% were classified as non-dengue, 12.7% without warning signs, 77.0% with warning signs and 1.0% with
severe dengue based on clinical diagnosis. Of these, 37% were misdiagnosed as non-dengue, highlighting the importance
of both clinical diagnosis and laboratory findings. Thrombocytopenia, prolonged clotting time, liver enzymes, ALT and AST served as good markers for dengue progression but could not distinguish between patients with and without warning signs. HLA-A*24 and -B*57 were positively associated with Chinese and Indians patients with warning signs, respectively, whereas A*03 may be protective in the Malays. HLA-A*33 was also positively associated in patients with warning signs when compared to those without. Dengue NS1, NS2A, NS4A and NS4B were found to be important T cell epitopes; however with no apparent difference between with and without warning signs patients. Distinction between the 2 groups of patients was also not observed in any of the cytokines analyzed; nevertheless, 12 were significantly differentially expressed at the
different phases of illness.

Background: Helicobacter pylori (H. pylori) infection is a risk factor for peptic ulcer. There have been no studies addressing environmental and dietary risk factors in western India. We conducted a case control study enrolling peptic ulcer patients in Pune, India. Materials and Methods: Risk factors for peptic ulcer and H. pylori infection were assessed in a participant interview. H. pylori status was assessed from stool by monoclonal antigen detection. Results: We enrolled 190 peptic ulcer, 35 stomach cancer patients, and 125 controls. Fifty-one percent (180/350) of the participants were infected with H. pylori. Lower socioeconomic status (SES) [odds ratio (OR): 1.10, 95% confidence interval (CI): 1.02-1.39], meat consumption (OR: 2.35, 95% CI: 1.30-4.23), smoking (OR: 2.23, 95% CI: 1.24-4.02), eating restaurant food (OR: 3.77, 95% CI: 1.39-10.23), and drinking nonfiltered or nonboiled water (OR: 1.05, 95% CI: 1.01-1.23) were risk factors for H. pylori infection. H. pylori infection (OR: 1.70, 95% CI:I. 03-2.89), meat (OR: 1.10, 95% CI: 1.02-1.75), fish (OR: 1.05, 95% CI: 1.02-1.89) consumption, and a family history of ulcer
(OR: 1.20, 95% CI: 1.08-1.60) were risk factors for peptic ulcer. Consumption of chili peppers (OR: 0.20, 95% CI: 0.10-0.37) and parasite infestation (OR: 0.44, 95% CI: 0.24-0.80) were protective against H. pylori infection. Conclusion: H. pylori infection is
associated with peptic ulcer. Lower SES, consumption of restaurant food, meat, nonfiltered water, and smoking are risk factors for H. pylori. Consumption of meat, fish, and a family history of peptic ulcer are risk factors for peptic ulcer. Consumption of chili
peppers and concurrent parasite infestation appear to be protective against H. pylori.

water-quality testing
Research Subject Categories::MEDICINE
Each year recreational water users descend on national parks by the
millions. U.S. Environmental Protection Agency (EPA) regulations require monitoring
waters for fecal indicator bacteria in order to safeguard human health, and obtaining
results using the culturing method takes 18 hours or more of analytical time. Thus,
under this surveillance regime swimmers can be exposed to waterborne disease
organisms before health advisories can be issued. To address the need for timelier
notification of recreational water quality, the EPA has evaluated and approved new and
faster testing methods as of November 2012. This article discusses new recreational
water testing methodologies such as qPCR, empirical predictive modeling, rainfall
threshold levels, and advanced notification options for park managers to consider and
tailor to their needs.

Dengue Virus is a re-emerging infectious disease that is transmitted through mosquitos.
Dengue is a significant health concern because of the number of people it affects globally. Clinical diagnosis of dengue is not possible because the symptoms are similar to other febrile-diseases. Therefore, the only way to truly diagnose dengue is via laboratory methods. Many diagnostics tests exist to accomplish this; however, these tests have disadvantages. Rapid, point-of-care, commercially available diagnostic test kits have come onto the market to bridge the gap for those without high tech laboratories and personnel. This paper extends the knowledge of a meta-analysis conducted in 2011 on the performance of commercially available diagnostic tests. The purpose of
this review was to compare and contrast the accuracy of commercial dengue diagnostic tests.

Research Subject Categories::MEDICINE
Aims: This paper aims to compare the effectiveness of current mosquito control programs in the control of dengue in a developed versus a developing country.
Study Design: Systematic Review and Analysis. Place and Duration of Study: Department of Global Health, University of South Florida, Tampa, Florida, USA between August 2013 and July 2014. Methodology: Systematic literature search of published and grey literature was done using the following databases: MEDLINE, AGRICOLA, BMC, DOAJ, Web of Science, the Cochrane Library, WHOLIS and Google Scholar. Relevant data were then extracted and analyzed. Results: Developing countries usually start up vector control activities after an epidemic has started, resulting in a lower impact on the control and prevention of dengue. Some developing countries, despite having sustainable vector control programs, still have a high incidence of dengue. Some studies have shown that factors such as defective urban planning, low socioeconomic status and poor physical housing conditions in some endemic locations within the developing countries may account for the high incidence of dengue cases.

Motoneuron loss

AChR
The ErbB2 tyrosine kinase functions as coreceptor for the neuregulin receptors ErbB3 and ErbB4 and can
participate in signaling of EGF receptor (ErbB1), interleukin receptor gp130, and G-protein coupled receptors.
ErbB2−/− mice die at midgestation because of heart malformation. Here, we report a genetic rescue of their
heart development by myocardial expression of erbB2 cDNA that allows survival of the mutants to birth. In
rescued erbB2 mutants, Schwann cells are lacking. Motoneurons form and can project to muscle, but nerves
are poorly fasciculated and disorganized. Neuromuscular junctions form, as reflected in clustering of AChR
and postsynaptic expression of the genes encoding the a-AChR, AChE, e-AChR, and the RI subunit of the
cAMP protein kinase. However, a severe loss of motoneurons on cervical and lumbar, but not on thoracic
levels occurs. Our results define the roles of Schwann cells during motoneuron and synapse development, and
reveal different survival requirements for distinct motoneuron populations

Placental Failure in Mice Lacking the Mammalian Homolog of Glial Cells Missing, GCMa
Riethmacher-Sonnenberg, Eva
Research Subject Categories::NATURAL SCIENCES::Biology::Organism biology::Microbiology
Drosophila melanogaster GCM
Glial Cells Missing
Mammalian Homolog
The GCM family of transcription factors consists of Drosophila melanogaster GCM, an important regulator
of gliogenesis in the fly, and its two mammalian homologs, GCMa and GCMb. To clarify the function of these
mammalian homologs, we deleted GCMa in mice. Genetic ablation of murine GCMa (mGCMa) is embryonic
lethal, with mice dying between 9.5 and 10 days postcoitum. At the time of death, no abnormalities were
apparent in the embryo proper. Nervous system development, in particular, was not impaired, as might have
been expected in analogy to Drosophila GCM. Instead, placental failure was the cause of death. In agreement
with the selective expression of mGCMa in labyrinthine trophoblasts, mutant placentas did not develop a
functional labyrinth layer, which is necessary for nutrient and gas exchange between maternal and fetal blood.
Only a few fetal blood vessels entered the placenta, and these failed to thrive and branch normally. Labyrinthine
trophoblasts did not differentiate. All other layers of the placenta, including spongiotrophoblast and
giant cell layer, formed normally. Our results indicate that mGCMa plays a critical role in trophoblast
differentiation and the signal transduction processes required for normal vascularization of the placenta

Neuregulin ligands and their ErbB receptors are important for the
development of Schwann cells, the glial cells of the peripheral
nervous system (PNS). ErbB3 deficiency is characterized by a
complete loss of Schwann cells along axons of the peripheral nerves,
impaired fasciculation and neuronal cell death. We performed
comparative gene expression analysis of dorsal root ganglia (DRG)
explant cultures from ErbB3-deficient and wild-type mice in order to
identify genes that are involved in Schwann cell development and
migration. The extracellular matrix (ECM) gene periostin was found to
exhibit the most prominent down regulation in ErbB3-deficient DRG.
Expression analysis revealed that the periostin-expressing cell
population in the PNS corresponds to Schwann cell precursors and
Schwann cells, and is particularly high in migratory Schwann cells.
Furthermore, stimulation of Schwann cells with neuregulin-1 (NRG1)
or transforming growth factor β (TGFβ-1) resulted in an upregulation of
periostin expression. Interestingly, DRG explant cultures of periostindeficient
mice revealed a significant reduction of the number of
migrating Schwann cells. These data demonstrate that the
expression of periostin is stimulated by ErbB ligand NRG1 and
influences the migration of Schwann cell precursors

c-ros tyrosine kinase receptor

The c-ros gene was originally identified in mutant form as an oncogene. The proto-oncogene encodes a
tyrosine kinase receptor that is expressed in a small number of epithelial cell types, including those of the
epididymis. Targeted mutations of c-ros in the mouse reveal an essential role of the gene in male fertility.
Male c-ros -1- animals do not reproduce, whereas the fertility of female animals is not affected. We
demonstrate that c-ros is not required in a cell autonomous manner for male germ cell development or
function. The gene, therefore, does not affect sperm generation or function in a direct manner. The primary
defect in the mutant animals was located in the epididymis, showing that c-ros controls appropriate
development of the epithelia, particularly regionalization and terminal differentiation. The epididymal defect
does not interfere with production or storage of sperm but, rather, with sperm maturation and the ability of
sperm to fertilize in vivo. Interestingly, sperm isolated from c-ros - / - animals can fertilize in vitro. Our
results highlight the essential role of the epididymis in male fertility and demonstrate a highly specific
function of the c-ros receptor tyrosine kinase during development of distinct epithelial cells

Scatter Factor/Hepatocyte Growth Factor and Its Receptor, the c-met Tyrosine Kinase, Can Mediate a Signal Exchange between Mesenchyme and Epithelia during Mouse Development
Sonnenberg-Riethmacher, Eva
Scatter factor/hepatocyte growth factor
Scatter factor/hepatocyte growth factor
(SF/HGF) has potent motogenic, mitogenic, and morphogenetic
activities on epithelial cells in vitro. The cell
surface receptor for this factor was recently identified:
it is the product of the c - m e t protooncogene, a
receptor-type tyrosine kinase. We report here the
novel and distinct expression patterns of SF/HGF and
its receptor during mouse development, which was determined
by a combination of in situ hybridization and
RNase protection experiments. Predominantly, we detect
transcripts of c - m e t in epithelial cells of various
developing organs, whereas the ligand is expressed in
distinct mesenchymal cells in close vicinity. In addition,
transient SF/HGF and c - m e t expression is found
at certain sites of muscle formation; transient expression
of the c - m e t gene is also detected in developing
motoneurons. SF/HGF and the c-met receptor might
thus play multiple developmental roles, most notably,
mediate a signal given by mesenchyme and received
by epithelial. Mesenchymal signals are known to govern
differentiation and morphogenesis of many epithelia,
but the molecular nature of the signals has remained
poorly understood. Therefore, the known
biological activities of SF/HGF in vitro and the embryonal
expression pattern reported here indicate that
this mesenchymal factor can transmit morphogenetic
signals in epithelial development and suggest a molecular
mechanism for mesenchymal epithelial interactions.

Peripheral nerve regeneration
Matrilins are adaptor proteins of the extracellular matrix
involved in the formation of both collagen-dependent and
collagen-independent filamentous networks. Although their
molecular structure and binding partners have been
characterized, the functional roles of the four matrilin family
members in vivo are still largely unknown. Here, we show that
matrilin 2, expressed in pre-myelinating Schwann cells during
normal development, profoundly influences the behaviour of
glial cells and neurons in vitro. When offered as a uniform
substrate, matrilin 2 increased neurite outgrowth of dorsal root
ganglia (DRG) neurons and enhanced the migration of both cell
line- and embryonic DRG-derived Schwann cells. Vice versa,
axonal outgrowth and cell migration were decreased in DRG
cultures prepared from matrilin-2-deficient mice compared with
wild-type (wt) cultures. In stripe assays, matrilin 2 alone was
sufficient to guide axonal growth and, interestingly, axons
favoured the combination of matrilin 2 and laminin over
laminin alone. In vivo, matrilin 2 was strongly upregulated in
injured peripheral nerves of adult wild-type mice and failure
of protein upregulation in knockout mice resulted in delayed
regrowth of regenerating axons and delayed time-course of
functional recovery. Strikingly, the functional recovery 2 months
after nerve injury was inferior in matrilin-2-deficient mice
compared with wild-type littermates, although motoneuron
survival, quality of axonal regeneration, estimated by analyses
of axonal diameters and degrees of myelination, and Schwann
cell proliferation were not influenced by the mutation. These
results show that matrilin 2 is a permissive substrate for axonal
growth and cell migration, and that it is required for successful
nerve regeneration

Honey: an immunomodulatory agent for disorders of the skin

honey

Studies have shown that honeys from around the world can inhibit the growth of a range of dermatologically important microbes. As well as reports of the antimicrobial properties of honey, a number of recent in vitro and in vivo studies suggest that honey is able to modulate immunological parameters related to the skin immune system. Paradoxically, both immune-stimulatory and anti-inflammatory effects have been observed. In this review, scientific research investigating the immunomodulatory properties of honeys from around the world, in relation to disorders of the skin, is evaluated. Whilst there is sufficient evidence to suggest that honey does indeed have immunomodulatory properties, which may at least partially explain the ability of honey to promote the healing of wounds, there are still gaps in the scientific knowledge and literature. More research is necessary for a more complete understanding of the immune modulating properties of honey and to enable the utilisation of honey as an immune-modulating agent in dermatology

Resistance of pathogenic micro-organisms to antibiotics is a serious global health concern. In this review, research investigating the antimicrobial properties of honeys from around the world, against skin relevant microbes is evaluated. A plethora of in vitro studies have revealed that honeys from all over the world have potent microbicidal activity against dermatologically important microbes. Moreover, in vitro studies have shown that honey can reduce microbial pathogenicity as well as reverse anti-microbial resistance. Studies investigating the antimicrobial properties of honey in vivo have been more controversial. It is evident that innovative research is required to exploit the anti-microbial properties of honey for clinical use and to determine the efficacy of honey in the treatment of a range of skin disorders with a microbiological aetiology

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is the most common form of Polycystic Kidney Disease (PKD) and occurs at a frequency of 1/800 to 1/1000 affecting all ethnic groups worldwide. ADPKD shows significant intrafamilial phenotypic variability in the rate of disease progression and extra-renal manifestations, which suggests the involvement of heritable modifier genes. Here we show that the PKD1 gene can act as a
disease causing and a disease modifier gene in ADPKD patients.

Herein, a new method for the detection of 13 different pharmaceuticals and one metabolite in surface water at low ng/L levels is described. The method utilizes ultra performance liquid chromatography–tandem mass spectrometry and a solid-phase extraction sample preparation. Mean method detection limits were low (4.10 ng/L) and overall solid-phase extraction recovery and reproducibility was adequate (mean recovery, 77.9%; mean RSD, 7.3%). The method allows for quick run times and minimal solvent use as compared with other previously reported high performance
liquid chromatography-based methods. Application of this method for the detection of pharmaceuticals in Tennessee River surfacewater determined
that caffeine, sulfamethoxazole, and carbamazepine were frequently detected (100% of samples). Trimethoprim was moderately detected (30% of samples); acetaminophen, atorvastatin, and lovastatin were infrequently detected (10% of samples); and ciprofloxacin, diltiazem, fluoxetine, levofloxacin, norfluoxetine, ranitidine, and sertraline were not detected. This study reports the first detection of lovastatin in surface water.

MOOC
MOOCs are massive open online courses that are globally accessible, free of charge. Given their cost-free and open accessibility, it is surprising that only a few institutions have offered MOOCs from low- and middle-income countries (LMICs). Pakistan recently made this short list of LMICs as the first two MOOCs were launched from the country, in 2014 and 2016. Drawing from that experience, the organizers of that course present a roadmap for LMIC institutions for developing a MOOC, focusing especially on the technological and pedagogical limitations that an LMIC institution might find deterring.

Exogenous IgE acts as an adjuvant in tumor vaccination in mice, and therefore a direct role of endogenous IgE in tumor immunosurveillance was investigated. By using genetically engineered mice, we found that IgE ablation rendered mice more susceptible to the growth of transplantable tumors. Conversely, a strengthened IgE response provided mice with partial or complete resistance to tumor growth, depending on the tumor type. By genetic crosses, we showed that IgE-mediated tumor protection was mostly lost in mice lacking FceRI. Tumor protection was also lost after depletion of CD8+ T cells, highlighting a cross-Talk between IgE and T cell- mediated tumor immunosurveillance. Our findings provide the rationale for clinical observations that relate atopy with a lower risk for developing cancer and open new avenues for the design of immunotherapeutics relevant for clinical oncology.

A 40-year-old man, diagnosed with decompensated liver cirrhosis because of hepatitis C virus, was on the wait list for a liver transplant when he began treatment with the direct-acting antivirals simeprevir 150 mg and sofosbuvir 400 mg. The patient demonstrated end of treatment virologic response at week 12, normal bilirubin, and alanine aminotransferase levels, resolution of ascites, with downgrading to subcompensated liver cirrhosis, and was removed from the liver transplant wait list. However, the patient did not comply with the recommended duration of the antiviral treatment of at least 16 weeks, which resulted in hepatitis C virus relapse at posttreatment week 12. Later, the patient started an alternative regimen that included a combination of ombitasvir 12.5 mg, paritaprevir 75 mg, ritonavir 50 mg, and dasabuvir 250 mg for 24 weeks and achieved a sustained virologic response. However, despite undetectable hepatitis C virus, the patient began to deteriorate again and was again put on the liver transplant wait list. This first described clinical case in Kazakhstan of successful antiviral therapy with 2 consecutive directacting agents demonstrates the importance of virus eradication of pretransplant survival extension and delaying the need for liver transplant.

Background: Children's exposure to lead poses a significant risk for neurobehavioral consequences. Existing studies documented lead contamination in residential soil in mining and smelting communities in Armenia. This study aimed to assess blood lead levels (BLL) in children living in three communities in Armenia adjacent to metal mining and smelting industries, and related risk factors. Methods: This cross-sectional study included 159 children born from 2007 to 2009 and living in Alaverdi and Akhtala communities and Erebuni district in Yerevan - the capital city. The BLL was measured with a portable LeadCare II Blood Lead Analyzer; a survey was conducted with primary caregivers. Results: Overall Geometric Mean (GM) of BLL was 6.0 μg/dl: 6.8 for Akhtala, 6.4 for Alaverdi and 5.1 for Yerevan. In the sample 68.6 % of children had BLL above CDC defined reference level of 5 μg/dl: 83.8 % in Akhtala, 72.5 % in Alaverdi, and 52.8 % in Yerevan. Caregiver's lower education, dusting furniture less than daily, and housing distance from toxic source(s) were risk factors for higher BLL. Additional analysis for separate communities demonstrated interaction between housing distance from toxic source(s) and type of window in Erebuni district of Yerevan. Conclusions: The study demonstrated that children in three communities adjacent to metal mining and smelting industries were exposed to lead. Investigation of the risk factors suggested that in addition to promoting safe industrial practices at the national level, community-specific interventions could be implemented in low- and middle-income countries to reduce BLL among children.

To estimate the surgical volume and the incidence of in-hospital complications of RC in Armenia from 2005 to 2012, and to investigate potential risk factors of complications. The study utilized a retrospective chart review in a cohort of patients who had RC followed by either continent or conduit urinary diversion in all hospitals of Armenia from 2005 to 2012. A detailed chart review was conducted abstracting information on baseline demographic and clinical characteristics, surgical procedural details, postoperative management and in-hospital complications. Multivariable logistic regression analysis was applied to estimate the independent risk factors for developing ‘any postoperative complication’. The total study sample included 273 patients (mean age = 58.5 years, 93.4 % men). Overall, 28.9 % (n = 79) of patients had at least one in-hospital complication. The hospital mortality rate was 4.8 % (n = 13). The most frequent types of complications were wound-related (10.3 %), gastrointestinal (9.2 %) and infectious (7.0 %). The ischemic heart disease (OR = 3.3, 95 % CI 1.5–7.4), perioperative transfusion (OR = 2.0, 1.1–3.6), glucose level [OR = 0.71 (0.63–0.95)], and hospital type (OR = 2.3, 95 % CI 1.1–4.7) were independent predictors of postoperative complications. The rate of RC complications in Armenia was similar to those observed in other countries. Future prospective studies should evaluate the effect of RC complications on long-term outcomes and costs in Armenia. Policy recommendations should address the issues regarding surgeon training and hospital volume to decrease the risk of RC complications.

Sebocytes, which are characterized by lipid accumulation that leads to cell disruption, can be found in hair follicle-associated sebaceous glands (SGs) or in free SGs such as the Meibomian glands in the eyelids. Because genetic tools that allow targeting of sebocytes while maintaining intact epidermal lipids are lacking, the relevance of sebaceous lipids in health and disease remains poorly understood. Using Scd3, which is expressed exclusively in mature sebocytes, we established a mouse line with sebocyte-specific expression of Cre recombinase. Both RT-PCR analysis and crossing into Rosa26-lacZ reporter mice and KrasG12D mice confirmed Cre activity specifically in SGs, with no activity in other skin compartments. Importantly, loss of SCD3 function did not cause detectable phenotypical alterations, endorsing the usefulness of Scd3-Cre mice for further functional studies. Scd3-Cre-induced, diphtheria chain A toxin-mediated depletion of sebaceous lipids resulted in impaired water repulsion and thermoregulation, increased rates of UVB-induced epidermal apoptosis and caused a severe pathology of the ocular surface resembling Meibomian gland dysfunction. This novel mouse line will be useful for further investigating the roles of sebaceous lipids in skin and eye integrity.

Background: Alzheimer's disease is a multifactorial disorder that may be diagnosed earlier using a combination of tests rather than any single test. Search algorithms and optimization techniques in combination with model evaluation techniques have been used previously to perform the selection of suitable feature sets. Previously we successfully applied GA with LR to neuropsychological data contained within the The Australian Imaging, Biomarkers and Lifestyle (AIBL) study of aging, to select cognitive tests for prediction of progression of AD. This research addresses an Adaptive Genetic Algorithm (AGA) in combination with LR for identifying the best biomarker combination for prediction of the progression to AD. Results: The model has been explored in terms of parameter optimization to predict conversion from healthy stage to AD with high accuracy. Several feature sets were selected - the resulting prediction moddels showed higher area under the ROC values (0.83-0.89). The results has shown consistency with some of the medical research reported in literature. Conclusion: The AGA has proven useful in selecting the best combination of biomarkers for prediction of AD progression. The algorithm presented here is generic and can be extended to other data sets generated in projects that seek to identify combination of biomarkers or other features that are predictive of disease onset or progression.

Background: Hepatitis C virus (HCV) belongs to Flaviviridae family of viruses. HCV represents a major challenge to public health since its estimated global prevalence is 2.8% of the world's human population. The design and development of HCV vaccine has been hampered by rapid evolution of viral quasispecies resulting in antibody escape variants. HCV envelope glycoprotein E1 and E2 that mediate fusion and entry of the virus into host cells are primary targets of the host immune responses. Results: Structural characterization of E2 core protein and a broadly neutralizing antibody AR3C together with E1E2 sequence information enabled the analysis of B-cell epitope variability. The E2 binding site by AR3C and its surrounding area were identified from the crystal structure of E2c-AR3C complex. We clustered HCV strains using the concept of 'discontinuous motif/peptide' and classified B-cell epitopes based on their similarity. Conclusions: The assessment of antibody neutralizing coverage provides insights into potential cross-reactivity of the AR3C neutralizing antibody across a large number of HCV variants.

Biomarkers and signaling pathways of colorectal cancer stem cells

The progression of colorectal cancer is commonly characterized by accumulation of genetic or epigenetic abnormalities, altering regulation of gene expression as well as normal protein structures and functions. Nonetheless, there are some questions that remain to be elucidated, such as the origin of cancer cells and populations of cells initiating and propagating tumor development. Currently, there are two rival theories describing the process of carcinogenesis. One is the stochastic model, arguing that any cell is capable of initiating and triggering the development of cancer. Meanwhile, the cancer stem cell model hypothesizes that only a small fraction of stem cells possesses cancer-promoting properties. Typically, colorectal cancer stem cells (CSCs) share the same molecular signaling profiles with normal stem cells or embryonic stem cells, such as Wnt, Notch, TGF-β, and Hedgehog. Nevertheless, CSCs differ from normal stem cells and the bulk of tumor cells in their tumorigenic potential and susceptibility to chemotherapeutic drugs. This may be a possible explanation of the high percentage of cancer recurrence in patients who underwent chemotherapeutic treatment and surgery. This review article focuses on the colorectal cancer stem cell biomarkers and the role of upregulated signaling pathways implicated in the initiation and progression of colorectal cancer.

The treatment of cancer is becoming more precise, targeting specific oncogenic drivers with targeted molecular therapies. The epidermal growth factor receptor has been found to be over-expressed in a multitude of solid tumours. Immunohistochemistry is widely used in the fields of diagnostic and personalised medicine to localise and visualise disease specific proteins. To date the clinical utility of epidermal growth factor receptor immunohistochemistry in determining monoclonal antibody efficacy has remained somewhat inconclusive. The lack of an agreed reproducible scoring criteria for epidermal growth factor receptor immunohistochemistry has, in various clinical trials yielded conflicting results as to the use of epidermal growth factor receptor immunohistochemistry assay as a companion diagnostic. This has resulted in this test being removed from the licence for the drug panitumumab and not performed in clinical practice for cetuximab. In this review we explore the reasons behind this with a particular emphasis on colorectal cancer, and to suggest a way of resolving the situation through improving the precision of epidermal growth factor receptor immunohistochemistry with quantitative image analysis of digitised images complemented with companion molecular morphological techniques such as in situ hybridisation and section based gene mutation analysis.

Recently the American Society of Clinical Oncology and the College of American Pathologists have updated their clinical practice guidelines for HER2 testing in breast cancer. In order to evaluate these new recommendations, we have re-assessed the HER2 status of 6018 breast cancer cases of the screening population for the HERceptin adjuvant (HERA) trial that were originally centrally tested by fluorescence in situ hybridization based on the FDA-released test guidelines. According to the most recent 2013 ASCO/CAP recommendations, 3380 (56.2%) cases were classified as HER2 positive compared with 3359 (55.8%) applying the HERA/FDA scheme and 3339 (55.5%) applying the 2007 ASCO/CAP guidelines. Twenty-one cases switched from negative (HERA/FDA scheme) to positive (2013 ASCO/CAP guidelines). This group is characterized by a mean HER2 gene copy number of ≥6.0, polysomy or co-amplification of CEP17 with an average CEP17 count of 5, and with HER2 receptor overexpression in 75% of cases. On the basis of the HER2 gene copy number alone, we observe 494 cases (8.2%) that are in the equivocal range. Most of these cases (>80%) were also nondecisive by immunohistochemistry (score 2+) irrespective of whether ratio was . The number of equivocal cases that would require HER2 reflex testing decreases to 113 (1.9%) if in addition to the HER2 gene copy number also the ratio of HER2 and CEP17 copy numbers is considered via dual-color in situ hybridization. The combination of applying the HER2 mean gene copy number as well as the HER2/CEP17 ratio to define equivocal test decisions by fluorescence in situ hybridization as proposed by the current ASCO/CAP guidelines appears to be a more optimum approach to adopt in order to avoid or minimize reporting of false negative results. Using the mean HER2 gene copy number alone for decision making results in a significant increase of equivocal cases.

The main aim of oncologists worldwide is to understand and then intervene in the primary tumor initiation and propagation mechanisms. This is essential to allow targeted elimination of cancer cells without altering normal mitotic cells. Currently, there are two main rival theories describing the process of tumorigenesis. According to the Stochastic Model, potentially any cell, once defunct, is capable of initiating carcinogenesis. Alternatively the Cancer Stem Cell (CSC) Model posits that only a small fraction of undifferentiated tumor cells are capable of triggering carcinogenesis. Like healthy stem cells, CSCs are also characterized by a capacity for self-renewal and the ability to generate differentiated progeny, possibly mediating treatment resistance, thus leading to tumor recurrence and metastasis. Moreover, molecular signaling profiles are similar between CSCs and normal stem cells, including Wnt, Notch and Hedgehog pathways. Therefore, development of novel chemotherapeutic agents and proteins (e.g., enzymes and antibodies) specifically targeting CSCs are attractive pharmaceutical candidates. This article describes small molecule inhibitors of stem cell pathways Wnt, Notch and Hedgehog, and their recent chemotherapy clinical trials.

The mechanisms of immune response to cancer have been studied extensively and great effort has been invested into harnessing the therapeutic potential of the immune system. Immunotherapies have seen significant advances in the past 20 years, but the full potential of protective and therapeutic cancer immunotherapies has yet to be fulfilled. The insufficient efficacy of existing treatments can be attributed to a number of biological and technical issues. In this review, we detail the current limitations of immunotherapy target selection and design, and review computational methods to streamline therapy target discovery in a bioinformatics analysis pipeline. We describe specialized bioinformatics tools and databases for three main bottlenecks in immunotherapy target discovery: the cataloging of potentially antigenic proteins, the identification of potential HLA binders, and the selection epitopes and co-targets for single-epitope and multi-epitope strategies. We provide examples of application to the well-known tumor antigen HER2 and suggest bioinformatics methods to ameliorate therapy resistance and ensure efficient and lasting control of tumors.

Background: Proteomics research is enabled with the high-throughput technologies, but our ability to identify expressed proteome is limited in small samples. The coverage and consistency of proteome expression are critical problems in proteomics. Here, we propose pathway analysis and combination of microproteomics and transcriptomics analyses to improve mass-spectrometry protein identification from small size samples. Results: Multiple proteomics runs using MCF-7 cell line detected 4,957 expressed proteins. About 80% of expressed proteins were present in MCF-7 transcripts data; highly expressed transcripts are more likely to have expressed proteins. Approximately 1,000 proteins were detected in each run of the small sample proteomics. These proteins were mapped to gene symbols and compared with gene sets representing canonical pathways, more than 4,000 genes were extracted from the enriched gene sets. The identified canonical pathways were largely overlapping between individual runs. Of identified pathways 182 were shared between three individual small sample runs. Conclusions: Current technologies enable us to directly 10% of expressed proteomes from small sample comprising as few as 50 cells. We used knowledge-based approaches to elucidate the missing proteome that can be verified by targeted proteomics. This knowledge-based approach includes pathway analysis and combination of gene expression and protein expression data for target prioritization. Genes present in both the enriched gene sets (canonical pathways collection) and in small sample proteomics data correspond to approximately 50% of expressed proteomes in larger sample proteomics data. In addition, 90% of targets from canonical pathways were estimated to be expressed. The comparison of proteomics and transcriptomics data, suggests that highly expressed transcripts have high probability of protein expression. However, approximately 10% of expressed proteins could not be matched with the expressed transcripts.

Ability of electromagnetic fields (EMF) to stimulate cell proliferation and differentiation has attracted the attention of many laboratories specialized in regenerative medicine over the past number of decades. Recent studies have shed light on bio-effects induced by the EMF and how they might be harnessed to help control tissue regeneration and wound healing. Number of recent reports suggests that EMF has a positive impact at different stages of healing. Processes impacted by EMF include, but are not limited to, cell migration and proliferation, expression of growth factors, nitric oxide signalling, cytokine modulation, and more. These effects have been detected even during application of low frequencies (range: 30-300 kHz) and extremely low frequencies (range: 3-30 Hz). In this regard, special emphasis of this review is the applications of extremely low-frequency EMFs due to their bio-safety and therapeutic efficacy. The article also discusses combinatorial effect of EMF and mesenchymal stem cells for treatment of neurodegenerative diseases and bone tissue engineering. In addition, we discuss future perspectives of application of EMF for tissue engineering and use of metal nanoparticles activated by EMF for drug delivery and wound dressing.

Background: The majority of genetic biomarkers for human cancers are defined by statistical screening of high-throughput genomics data. While a large number of genetic biomarkers have been proposed for diagnostic and prognostic applications, only a small number have been applied in the clinic. Similarly, the use of proteomics methods for the discovery of cancer biomarkers is increasing. The emerging field of proteogenomics seeks to enrich the value of genomics and proteomics approaches by studying the intersection of genomics and proteomics data. This task is challenging due to the complex nature of transcriptional and translation regulatory mechanisms and the disparities between genomic and proteomic data from the same samples. In this study, we have examined tumor antigens as potential biomarkers for breast cancer using genomics and proteomics data from previously reported laser capture microdissected ER+ tumor samples. Results: We applied proteogenomic analyses to study the genetic aberrations of 32 tumor antigens determined in the proteomic data. We found that tumor antigens that are aberrantly expressed at the genetic level and expressed at the protein level, are likely involved in perturbing pathways directly linked to the hallmarks of cancer. The results found by proteogenomic analysis of the 32 tumor antigens studied here, capture largely the same pathway irregularities as those elucidated from large-scale screening of genomics analyses, where several thousands of genes are often found to be perturbed. Conclusion: Tumor antigens are a group of proteins recognized by the cells of the immune system. Specifically, they are recognized in tumor cells where they are present in larger than usual amounts, or are physiochemically altered to a degree at which they no longer resemble native human proteins. This proteogenomic analysis of 32 tumor antigens suggests that tumor antigens have the potential to be highly specific biomarkers for different cancers.

BlockLogo is a web-server application for the visualization of protein and nucleotide fragments, continuous protein sequence motifs, and discontinuous sequence motifs using calculation of block entropy from multiple sequence alignments. The user input consists of a multiple sequence alignment, selection of motif positions, type of sequence, and output format definition. The output has BlockLogo along with the sequence logo, and a table of motif frequencies. We deployed BlockLogo as an online application and have demonstrated its utility through examples that show visualization of T-cell epitopes and B-cell epitopes (both continuous and discontinuous). Our additional example shows a visualization and analysis of structural motifs that determine the specificity of peptide binding to HLA-DR molecules. The BlockLogo server also employs selected experimentally validated prediction algorithms to enable on-the-fly prediction of MHC binding affinity to 15 common HLA class I and class II alleles as well as visual analysis of discontinuous epitopes from multiple sequence alignments. It enables the visualization and analysis of structural and functional motifs that are usually described as regular expressions. It provides a compact view of discontinuous motifs composed of distant positions within biological sequences. BlockLogo is available at: http://research4.dfci.harvard.edu/cvc/blocklogo/ and http://met-hilab.bu.edu/blocklogo/.

Oxidative stress and inflammation play major roles in the pathogenesis of coronary heart disease including myocardial infarction (MI). The pathological progression following MI is very complex and involves a number of cell populations including cells localized within the heart, as well as cells recruited from the circulation and other tissues that participate in inflammatory and reparative processes. These cells, with their secretory factors, have pleiotropic effects that depend on the stage of inflammation and regeneration. Excessive inflammation leads to enlargement of the infarction site, pathological remodeling and eventually, heart dysfunction. Stem cell therapy represents a unique and innovative approach to ameliorate oxidative stress and inflammation caused by ischemic heart disease. Consequently, it is crucial to understand the crosstalk between stem cells and other cells involved in post-MI cardiac tissue repair, especially immune cells, in order to harness the beneficial effects of the immune response following MI and further improve stem cell-mediated cardiac regeneration. This paper reviews the recent findings on the role of antioxidation and immunomodulation in postnatal multipotent stem cell-mediated cardiac repair following ischemic heart disease, particularly acute MI and focuses specifically on mesenchymal, muscle and blood-vessel-derived stem cells due to their antioxidant and immunomodulatory properties.

The proper management of patients infected with dengue virus requires early detection. Here, real-time molecular assays have proven useful but have limitations, whereas ELISAs that detect antibodies are still favored but results are obtained too late to be of clinical value. The production of DENV NS1 peaks early during infection and its detection can combine the advantages of both diagnostic approaches. Methods. This study compared assays currently used for detecting DENV infection at the Florida Department of Health including anti-DENV IgM and IgG ELISAs as well as qRT-PCR, against a commercially available DENV NS1 ELISA. These comparisons weremade among a group of 21 human sera. Results. Nine of 14 (64.3%) DENV qRT-PCR+ samples were also DENV NS1+. Interestingly, the 5 NS1− samples that were qRT-PCR+ were additionally IgM− and IgG+ suggesting a
nonprimary infection. Compared to qRT-PCR, the NS1 assay had a sensitivity of 64.3%, specificity 100%, PPV of 100%, and NPV of 58.3%. Conclusions.The NS1 ELISA performed as expected in known DENV qRT-PCR+ samples; however negative NS1 results for qRT-PCR+ and IgG+ sera seemingly reduced the usefulness of the NS1 ELISA for nonprimary cases. We therefore conclude thatdiagnosis obtained via DENV NS1 ELISA deserves further investigation.

floxed diphtheria toxin fragment
Depression and anxiety involve hippocampal dysfunction, but the specific relationship
between these mood disorders and adult hippocampal dentate gyrus neurogenesis remains unclear. In both humans with MDD and rodent models of depression, administration of antidepressants increases DG progenitor and granule cell number, yet rodents with induced ablation of DG neurogenesis typically do not demonstrate depressive- or anxiety-like behaviors. The conflicting data may be explained by the varied duration and degree to which adult neurogenesis is reduced in different rodent neurogenesis ablation models. In order to test this hypothesis we examined how a transient–rather than permanent–inducible reduction in neurogenesis would alter depressive- and anxiety-like behaviors. Transgenic Nestin-CreERT2/floxed diphtheria toxin fragment A (DTA) mice (Cre+DTA+) and littermates (Cre+DTA-; control) were given tamoxifen (TAM) to induce recombination and decrease nestin-expressing stem cells and their progeny. The decreased neurogenesis was transient: 12 days post-TAM Cre+DTA+ mice had fewer DG proliferating Ki67+ cells and fewer DCX+ neuroblasts/immature neurons relative to control, but 30 days post-TAM Cre+DTA+mice had the same DCX+ cell number as control. This ability of DG neurogenesis to recover after partial ablation also correlated with changes in behavior. Relative to control, Cre+DTA+ mice tested between 12–30 days post-TAM displayed indices of a stress-induced anxiety phenotype–longer latency to consume highly palatable food in the unfamiliar cage in the novelty-induced hypophagia test, and a depression phenotype–longer time of immobility in the tail suspension test, but Cre+DTA+ mice tested after 30 days post-TAM did not. These findings suggest a functional association between adult neurogenesis and stress induced anxiety- and depressive-like behaviors, where induced reduction in DCX+ cells at the time of behavioral testing is coupled with stress-induced anxiety and a depressive phenotype, and recovery of DCX+ cell number corresponds to normalization of these behaviors.

Objectives: Human papillomavirus is themain causative agent for cervical cancer. However, few data are available about HPV prevalence in Kazakhstan. The aims of this study were to genotype HPV DNA in Pap smear samples of women to determine prevalence of carcinogenic HPV types in Astana, Kazakhstan and to analyze the association between HPV positivity and the cytology results of patient samples.
Methods: Pap smear materials were obtained from 140 patients aged 18-59, who visited the outpatient gynecological clinic. Microscopic examination was done to detect dysplasia, and HPV genotyping was done using real-time multiplex PCR. Results: HPV testing showed that among 61 HPV positive patients, the most prevalent types were 16 and 18. Microscopic examination showed that 79% of the samples had normal cytology, while 13% had CIN grade I, 5% had CIN grade II, and 3% had CIN grade III. The analysis revealed that 12% of the samples had CIN cytology and presence of HPV. Approximately 31% had HPV without cervical dysplasia, while 8% of samples were CIN positive without HPV infection. A statistically significant relationship between HPV 16 and HPV 33 positive samples and CIN grade II and III was found. Conclusions: Overall, this study will help to strengthen and guide health policy implementation of primary and secondary cervical cancer prevention strategies in Kazakhstan.2016 The Author(s).

Composite monolithic adsorbents were prepared by the incorporation of neutral polystyrene divinylbenzene (PS-DVB) microparticles into macroporous polymer structures produced by cryogelation of agarose or poly(vinyl alcohol). The composite
materials exhibited excellent flow-through properties. Scanning electron microscopy of the composite cryogels revealed that the microparticles were covered by thin films of poly(vinyl alcohol) or agarose and thus were withheld in the monolith structure. Plain PS-DVB microparticles showed efficient adsorption of albumin-bound toxins related to liver failure (bilirubin and cholic acid) and of cytokines (tumor necrosis factor-alpha and interleukin-6). The rates of adsorption and the amount of adsorbed factors were lower for the embedded microparticles as compared to the parent PS-DVB microparticles, indicating the importance of the accessibility of the adsorbent pores. Still, the macroporous composite materials showed efficient adsorption of albuminbound
toxins related to liver failure as well as efficient binding of cytokines, combined with good blood compatibility. Thus, the incorporation of microparticles into macroporous polymer structures may provide an option for the development of adsorption modules for extracorporeal blood purification.

Depression and anxiety involve hippocampal dysfunction, but the specific relationship
between these mood disorders and adult hippocampal dentate gyrus neurogenesis remains unclear. In both humans with MDD and rodent models of depression, administration of antidepressants increases DG progenitor and granule cell number, yet rodents with induced ablation of DG neurogenesis typically do not demonstrate depressive- or anxiety-like behaviors. The conflicting data may be explained by the varied duration and degree to which adult neurogenesis is reduced in different rodent neurogenesis ablation models. In order to test this hypothesis we examined how a transient–rather than permanent–inducible reduction in neurogenesis would alter depressive- and anxiety-like behaviors. Transgenic Nestin-CreERT2/floxed diphtheria toxin fragment A (DTA) mice (Cre+DTA+) and littermates (Cre+DTA-; control) were given tamoxifen (TAM) to induce recombination and decrease nestin-expressing stem cells and their progeny. The decreased neurogenesis was transient: 12 days post-TAM Cre+DTA+ mice had fewer DG proliferating Ki67+ cells and fewer DCX+ neuroblasts/immature neurons relative to control, but 30 days post-TAM Cre+DTA+ mice had the same DCX+ cell number as control. This ability of DG neurogenesis to recover after partial ablation also correlated with changes in behavior. Relative to control, Cre+DTA+ mice tested between 12–30 days post-TAM displayed indices of a stress-induced anxiety phenotype–longer latency to consume highly palatable food in the unfamiliar cage in the novelty-induced hypophagia test, and a depression phenotype–longer time of immobility in
the tail suspension test, but Cre+DTA+ mice tested after 30 days post-TAM did not. These
findings suggest a functional association between adult neurogenesis and stress induced anxiety- and depressive-like behaviors, where induced reduction in DCX+ cells at the time
of behavioral testing is coupled with stress-induced anxiety and a depressive phenotype,
and recovery of DCX+ cell number corresponds to normalization of these behaviors.

PHP127 Development of Hta In Kazakhstan
Bektur, C
HTA was introduced in Kazakhstan in 2009 as a result of an agreement of Kazakhstani Government with World Bank. As a consequence of this project, an HTA unit was created as part of Republican Centre of Healthcare Development(RCHD). There is lack of evidence on HTA concept in Kazakhstan, therefore, this research aims to gather information on the current state of development, processes and resources used in HTA in the country.

Tuberculosis diagnosis

Summary Tuberculosis (TB) remains a major public health concern in most low-income countries. Hence, rapid and sensitive TB diagnostics play an important role in detecting and preventing the disease. In addition to established diagnostic methods, several new approaches have been reported. Some techniques are simple but time-consuming, while others require complex instrumentation. One prominent and readily available approach is to detect proteins that Mycobacterium tuberculosis secretes, such as Mpt64, the 6-kDa early secreted antigenic target (Esat6), the 10-kDa culture filtrate protein (Cfp10), and the antigen 85 (Ag85) complex. Although their functions are not fully understood, a growing body of molecular evidence implicates them in M. tuberculosis virulence. Currently these biomarkers are either being used or investigated for use in skin patch tests, biosensor analyses, and immunochromatographic, immunohistochemical, polymerase chain reaction-based, and enzyme-linked immunosorbent assays. This review provides a comprehensive discussion of the roles these immunodominant antigens play in M. tuberculosis pathogenesis and compares diagnostic methods based on the detection of these proteins with more established tests for TB.

Effect of azelnidipine on beta-amyloid peptide induced dysfunction of cerebral endothelial cells in vitro
Askarova, Sholpan
Tsoy, Andrey
Teng, Tao
Lee, James
Zhumadilov, Zhaxybay
There is evidence that the receptor for advanced glycation endproducts (RAGE) is a binding site for amyloid β peptide (Aβ). RAGE is a multiligand cell surface receptor which is normally expressed in brain endothelium and, at low levels, in microglia and neurons. However, in Alzheimer's disease (AD) brains RAGE expression is increased by several-fold in cerebral endothelial cells (CECs), astrocytes, microglia, and neurons. Recent studies have demonstrated that RAGE is an important therapeutic target in AD. Therefore, there is a need to investigate new promising Aβ/RAGE axis blockers. It has been shown that azelnidipine (a highly lipid-soluble dihydropyridine-based calcium channel blocker) had a strong positive effect in RAGE-associated blood vessel damage in nondiabetic patients with stage I or II chronic kidney disease. In this study, we examined the effects of azelnidipine on A β 42 -induced activation of NADPH oxidase and consequent reactive oxygen species (ROS) generation, activation of NF-κB, ERK1/2 phosphorylation in CECs, and expression of P-selectin on the surface of the cells.

Role of ros in ab42-mediated activation of cerebral endothelial cells
Tsoy, Andrey
Shalakhmetova, Tamara
Umbayev, Bauyrzhan
Askarova, Sholpan
There is evidence that the deposition of amyloid-beta peptide (Aβ) in brain parenchyma and brain vessels is the main cause of neuronal dysfunction in Alzheimer's disease (AD). Aβ exhibits multiple cytotoxic effects to neurons and causes dysfunction of the blood brain barrier (BBB). In the AD brains an increased deposition of Aβ in the cerebral vasculature is correlated with increased transmigration of blood-born inflammatory cells and neurovascular inflammation. However, regulatory mediators of these processes remain to be elucidated. In this study, we examined a role of ROS in actin polymerization and expression of adhesion molecules on the surface of the cerebral endothelial cells (CECs) that are activated by Aβ42.

Cerebral palsy, a syndrome of motor impairment resulting from a lesion in the developing brain, has a worldwide prevalence of 1·0–3·5 per 1000 livebirths.A life-course perspective needs to be adopted as more children live into their adolescence and adulthood. Individuals' participation in life and availability of family-centred services are very important and differ between countries. In low-income countries, most treatments are provided by families and multidisciplinary assessment is done in rural clinics.

CYP1A2 polymorphism does not modulate caffeine's effects on sprint performance or its metabolites during a soccer match simulation
Kingsley, M.
Devlin, B.
Belski, R.
Leveritt, M.
Chan, C.K.
The effectiveness of caffeine supplementation on exercise performance varies between individuals. Cytochrome P450 1A2 (CYP1A2) is an important enzyme that controls the primary catabolism of caffeine to paraxanthine, theobromine and theophylline, which are potent adenosine receptor antagonists. The cause of variation in responsiveness to caffeine might be associated with a (C/A) single nucleotide polymorphism of CYP1A2. This study assessed the influence of CYP1A2 polymorphism on caffeine metabolites and sprint performance during a soccer simulation protocol.

Tuberculosis-immune reconstitution inflammatory syndrome

IRIS
Immune reconstitution

Antiretrovirals
Abstract Tuberculosis-immune reconstitution inflammatory syndrome is an excessive immune response against Mycobacterium tuberculosis that may occur in either HIV-infected or uninfected patients, during or after completion of anti-TB therapy. In HIV-infected patients it occurs after initiation of antiretroviral therapy independently from an effective suppression of HIV viremia. There are two forms of IRIS: paradoxical or unmasking. Paradoxical IRIS is characterized by recurrent, new, or worsening symptoms of a treated case. Unmasking IRIS is an antiretroviral-associated inflammatory manifestation of a subclinical infection with a hastened presentation. The pathogenesis is incompletely understood and the epidemiology partially described. No specific tests can establish or rule out the diagnosis. Treatment is based on the use of anti-tuberculosis drugs sometime with adjunctive corticosteroids. Mortality is generally low.

Activated carbon (AC) has a long history of use for medical applications due to its very high adsorption capacity and ability to adsorb a large range of substances. Recent advances in carbon materials science have produced a new generation of ACs with improved mechanical properties and porous structure, in a range of forms and with a breadth of applications in oral medicine, hemoperfusion devices, and wound care beyond that of traditional usage. The history and progressive development of AC for these applications are described including more recent developments in synthetic resin-based materials with optimized porosity to bind high molecular-weight and protein-bound biological toxins poorly removed by current systems. These highly optimized materials open up a range of treatment strategies with great potential to reduce healthcare cost burden and target improved acute and chronic disease treatment regimes.

Abstract ObjectivesHuman papillomavirus is the main causative agent for cervical cancer. However, few data are available about HPV prevalence in Kazakhstan. The aims of this study were to genotype HPV DNA in Pap smear samples of women to determine prevalence of carcinogenic HPV types in Astana, Kazakhstan and to analyze the association between HPV positivity and the cytology results of patient samples. MethodsPap smear materials were obtained from 140 patients aged 18-59, who visited the outpatient gynecological clinic. Microscopic examination was done to detect dysplasia, and HPV genotyping was done using real-time multiplex PCR. ResultsHPV testing showed that among 61 HPV positive patients, the most prevalent types were 16 and 18. Microscopic examination showed that 79% of the samples had normal cytology, while 13% had CIN grade I, 5% had CIN grade II, and 3% had CIN grade III. The analysis revealed that 12% of the samples had CIN cytology and presence of HPV. Approximately 31% had HPV without cervical dysplasia, while 8% of samples were CIN positive without HPV infection. A statistically significant relationship between HPV 16 and HPV 33 positive samples and CIN grade II and III was found. ConclusionsOverall, this study will help to strengthen and guide health policy implementation of primary and secondary cervical cancer prevention strategies in Kazakhstan.

Food authentication is analytical process that validates label information about the food origin and production process. This review discusses emerging food authenticity indicators including rare earth elements, metabolic profiles, sensory profile evaluation, and microbial fingerprinting. A scientometric evaluation that highlights research trends and emerging approaches of this evolving field is presented. We analyzed and provided an insight into most commonly studied food types and drinks and highlighted the most promising authenticity markers for each major group. Finally, we discussed the data explosion that is emerging and discussed the developing trends in the field. The future of food authentication lies in Big Data since we are already collecting and analyzing huge amounts of data that converge from multiple sources. Big Data Analytics will include standardization of experiments, study design workflows, and of data reporting. Emerging data analytical tools will include integration of geographic information systems with climate information systems and metabolomics databases for precise spatio-temporal identification of food origin.

Resumen Introducción y objetivosLa variación en la relación presión/volumen telesistólica entre el reposo y el estrés máximo es un índice de contractilidad del ventrículo izquierdo independiente de la poscarga. Aún no está claro si depende del volumen telediastólico y hasta qué punto. El objetivo de este estudio es evaluar la dependencia de la variación de la relación presión/volumen telesistólica entre el reposo y estrés (Δ) y el volumen telediastólico en pacientes con ecocardiografía de estrés negativa y con todos los intervalos de función ventricular izquierda en reposo. MétodosAnalizamos los datos interpretables obtenidos de 891 pacientes (593 varones; 63 ± 12 años) con fracción de eyección del 47 ± 12%: 338 pacientes estaban sanos, prácticamente sanos o hipertensos; 229 tenían arteriopatía coronaria y 324, miocardiopatía dilatada isquémica o no isquémica. Se los estudió con ecocardiografía de estrés en ejercicio (n =172), dipiridamol (n = 482) o dobutamina (n = 237). La relación presión/volumen telesistólica se evaluó en reposo y en estrés máximo a partir de una medición bruta de la presión arterial sistólica mediante esfigmógrafo con manguito y el volumen telesistólico, por ecocardiografía bidimensional mediante el método de Simpson biplanar. ResultadosLos valores absolutos de la variación reposo-estrés en la relación presión/volumen telesistólica fueron más altos con ejercicio y dobutamina que con dipiridamol. En la población general, se observó relación inversa entre la relación presión/volumen telesistólica y el volumen telediastólico en reposo (r2 = 0,69; p < 0,001) y en estrés máximo (r2 = 0,56; p < 0,001), pero no se observó esta relación al considerar la variación reposo-estrés de la relación presión/volumen telesistólica (r2 = 0,13). ConclusionesEl volumen telediastólico ventricular izquierdo no afecta a la variación reposo-estrés de la relación presión/volumen telesistólica en ventrículos izquierdos normales o anómalos durante el estrés físico o farmacológico.

Abstract Introduction and objectivesThe variation between rest and peak stress end-systolic pressure-volume relation is an afterload-independent index of left ventricular contractility. Whether and to what extent it depends on end-diastolic volume remains unclear. The aim of this study was to assess the dependence of the delta rest-stress end-systolic pressure-volume relation on end-diastolic volume in patients with negative stress echo and all ranges of resting left ventricular function. MethodsWe analyzed interpretable data obtained in 891 patients (593 men, age 63 ± 12 years) with ejection fraction 47% ± 12%: 338 were normal or near-normal or hypertensive; 229 patients had coronary artery disease; and 324 patients had ischemic or nonischemic dilated cardiomyopathy. They were studied with exercise (n = 172), dipyridamole (n = 482) or dobutamine (n = 237) stress echocardiography. The end-systolic pressure-volume relation was evaluated at rest and peak stress from raw measurement of systolic arterial pressure by cuff sphygmomanometer and end-systolic volume by biplane Simpson rule 2-dimensional echocardiography. ResultsAbsolute values of delta rest-stress end-systolic pressure-volume relation were higher for exercise and dobutamine than for dipyridamole. In the overall population, an inverse relationship between end-systolic pressure-volume relation and end-diastolic volume was present at rest (r2 = 0.69, P < .001) and peak stress (r2 = 0.56, P < .001), but was absent if the delta rest-stress end-systolic pressure-volume relation was considered (r2 = 0.13). ConclusionsLeft ventricular end-diastolic volume does not affect the rest-stress changes in end-systolic pressure-volume relation in either normal or abnormal left ventricles during physical or pharmacological stress.

Summary The neocortex undergoes extensive developmental growth, but how its architecture adapts to expansion remains largely unknown. Here, we investigated how early born Cajal-Retzius (CR) neurons, which regulate the assembly of cortical circuits, maintain a dense superficial distribution in the growing neocortex. We found that CR cell density is sustained by an activity-dependent importation of olfactory CR cells, which migrate into the neocortex after they have acted as axonal guidepost cells in the olfactory system. Furthermore, using mouse genetics, we showed that CR cell density severely affects the architecture of layer 1, a key site of input integration for neocortical networks, leading to an excitation/inhibition ratio imbalance. Our study reveals that neurons reenter migration several days after their initial positioning, thereby performing sequential developmental roles in olfactory cortex and neocortex. This atypical process is essential to regulate CR cell density during growth, which in turn ensures the correct wiring of neocortical circuitry. Video Abstract

Gambling
college students
prevalence
associated problems
Background. The prevalence of probable pathological gamblers among college students worldwide doubled in 15 years. While gambling addiction causes financial and social losses, there is lack of studies on gambling involvement in Kazakhstan. Aims. The current research aims to find the prevalence of gambling, explore the link with sociodemographic and psychological variables among college and university students is Astana, Kazakhstan. The study also aims to evaluate the association between gambling and school satisfaction, which was not reported before. Methods. The analysis included questionnaires of 399 students from three universities and three colleges in Astana, using random sampling. The survey consisted of demographic questions, and scales on anxiety and depression, alcohol use, school satisfaction, family cohesion and suicide ideation. Results. From 399 questionnaires analyzed, 5.76% were classified as pathological gamblers according to the gambling scale used. The most popular gambling type was betting on sport events with bookmakers. 12.4% reported placing a bet through bookmakers at present time, and of them 91.5% were male, around half (46.8%) were categorized as some-problem gamblers, and one-third (36.1%) as pathological gamblers. Two-third of them (66%) did not reach legal age for gambling. Pathological gamblers in comparison with non-gamblers/non-problem gamblers are more likely to be male, aged older than 21, have alcohol use disorders, have lower family cohesion, more frequent suicide ideation, and their fathers have no after school education. Some-problem gamblers in comparison with non-gamblers/non-problem gamblers are more likely to be male, have lower school satisfaction, show symptoms of depression, and do not combine work and study. Conclusions. The study gives the first overview for gambling problem and associated problems among undergraduate students in Astana. Associates of problem gambling is consistent with the literature. Since every fourth male in the study places a bet with bookmakers, and majority had a gambling problem, there is need for developing interventions to increase awareness and prevent problem gambling and associated psychosocial problems.

Human papillomavirus (HPV)
Human Papilloma virus is one of the most common infections caused by a virus. Most importantly is the fact that this infection can lead to cervical cancer, which represents a great burden for Kazakhstani women. There is a vaccine to prevent cervical cancer. Kazakhstan has introduced human papilloma virus vaccination program. However, there are no published public health studies about behavioral perception towards HPV and HPV vaccination that could support and encourage such a vaccination program.

Obstacles and Opportunities of Pursuing a Career of a Surgeon for a Female Physician in Kazakhstan: A Qualitative Research Study
Zhumagali, Yenglik
gender discrimination
social stigma
Qualitative research methods
An important factor to consider the effectiveness of a healthcare workforce is a gender balance. A gender imbalance in an organizational structure can lead to poor performance of a health service organization. Determinants of women being underrepresented in a health service organization are discrimination, sexism, stereotyping, glass ceiling phenomenon, and inability to manage job and family. Though Kazakhstan is considered to be rated highly for human development, women are underrepresented in such medical specialties as surgery. To our knowledge, there have been no studies conducted on obstacles and opportunities for careers of women in medicine, specifically in surgery, in Kazakhstan.

Research Subject Categories::MEDICINE
Infertility is a global issue that affects millions (Sami,2006). According to the World Bank, the fertility rate has declining trend in Kazakhstan. Infertility does not have only medical consequences, it also leads to psychosocial and economic issues, thus has public health importance (Rouchou, 2013). Social consequences of infertility consist of stigma, marital instability, social health risks and domestic violence (Rouchou, 2013). This types of social aspects of infertility were detrimental in setting psychological issues in infertile people. The psychological problems included depression, anxiety and identity predicaments (Hasanpoor-Azghdy, 2014). Fertility has immense importance for infertile people. But infertility treatment is costly, thus can bring a financial burden to those who cannot afford it (White, 2005; Boivin, 2007). Knowledge of infertility risks and its treatment options can help to decrease the incidence of infertility by educating youth.

Glioma is considered to be a rare type of cancer of the central nervous system (CNS)
with the average age-adjusted incidence rate of 3.4 per 100, 000 population. Moreover,
gliomas are the most common type of malignant brain tumors among adult population. They account for about 80% of all diagnosed brain tumors originating from brain parenchyma. Despite achievements in medical treatment and technologies glioblastoma patients still have poor prognosis with 3-5% of surviving patients after 12-15 months following standard therapy. In addition, recent studies highlight importance of blood, and molecular markers in predicting presence of gliomas.

Antibiotic/antimicrobial resistance patterns of bacterial pathogens isolates from national research center for mother and child health in Astana, Kazakhstan

antimicrobial resistance
Escherichia coli
Klebsiella pneumoniae
The rapid emergence of drug resistant bacteria is occurring worldwide, endangering the efficacy of antibiotics, which have transformed medicine and saved millions of lives (1-6). Many decades after the first patients were treated with antibiotics, bacterial infections have again become a threat (7). The antibiotic resistance crisis has been attributed to the overuse and misuse of these medications, as well as a lack of new drug development by the pharmaceutical industry due to reduced economic incentives and challenging regulatory requirements.

Bullying
Bullying is one of the main negative phenomenon in children’s mental health development. Studies worldwide showed the association of bullying with different factors, such as gender, race, family and peer relationships, perceptions related to life, health etc. The situation of bullying is not yet explored in Kazakhstan due to absence of proper monitoring tools. The aim of this study was to (1) assess the prevalence of the bullying among school children aged 11-15 years old, and (2) examine patterns of the association between bullying and socio-demographic, mental and physical health characteristics among schoolchildren of Astana city, Kazakhstan.

Burnout of Medical Workers in Astana, Kazakhstan: Prevalence and Associated Factors.
Abdiorazova, Aigerim
Astana city
Burnout
Health problems
Burnout is a state of physical, mental, and emotional exhaustion that arises as a result of being involved in emotionally demanding work situations. It has been reported that burnout is associated with high employee turnover, absenteeism, and poor performance. Research suggests that medical workers are more susceptible to burnout due to the challenging nature of their work, compared to other occupations. Health problems, including incapacity to deal with stress and development of major diseases, shortage of medical workforce due to burnt out specialists leaving the field, reduced quality of care and increased risk of medical errors are the risks associated with burnout in medical workers. This cross-sectional study aimed to identify prevalence of burnout among medical workers in Astana, Kazakhstan using Copenhagen Burnout Inventory questionnaire, to determine associated factors, and to give recommendations based on the findings. The final sample of data collected from an online survey included 363 responses in total. Prevalence of high personal burnout showed to be 82.1% among Astana medical workers, high work-related burnout – 66.9%, and high patient-related burnout – 53.1%. Multiple logistic regression analysis showed that self-rated health status and overwork were the factors statistically significantly associated with personal burnout; age, self-rated health status and overwork were associated with work-related burnout; and overwork was associated with patient-related burnout. It is recommended that healthcare organizations promote healthy lifestyle among their workers, and trainings on burnout could be provided for staff as a measure of identifying and preventing burnout.

Factors associated with adult pulmonary TB treatment outcome: East Kazakhstan Region
Magzymova, Gulsim
Tuberculosis
treatment outcome
drug resistance
East-Kazakhstan region
Kazakhstan is in top 18 countries with the highest TB burden in European region [2, 9]. The tuberculosis burden for Kazakhstan is very high, annual years of healthy life lost per 100,000 people from tuberculosis in Kazakhstan has increased by 19.8% since 1990, an average of 0.9% a year. This research investigated factors associated with treatment outcome failure. The following factors has been examined: age, sex, residence, socio-economic status, year of admission, length of stay in the hospital, drug resistance, medical organization, hospital admission type. It has been found that following factors are associated with increased TB treatment outcome failure: being male by 17%; drug resistance by 206%; being emergency admitted to the hospital by 47%. Factors that are associated with decreased treatment outcome failure: being treated in Ust-Kamenogorsk TB center by 34%; being employed (as compared to being unemployed) by 36%; being student (as compared to being unemployed) by 65%; one additional day of stay by 1%. However, it should be admitted that obtained factors’ association are generalizable for East-Kazakhstan region only due to study design limitations.

internet addiction
In recent years, the Internet has become the most essential tool in both studying and entertainment, by giving the fast and easy access to all the information for students. However, uncontrolled excessive use of internet negatively influences a person’s life, leading him to “Internet addiction” (IA) or “Problematic Internet use”. Despite the fact, that more than half of Kazakhstani population (55.8 %), which is approximately 10 million, uses internet on a daily base, there is a lack of studies on internet addiction in Kazakhstan. Therefore, our study aims were: (1) to estimate the prevalence of IA among university and college students; (2) to explore the association of IA with various factors, related to socio-demographics, family relationships, mood and sleep disorders, self-esteem, physical and social activities, and academic performance of the students.

Suicide is the act of killing yourself. According to WHO about 800,000 people die by suicide annually and many more attempt it. The evidence shows that global burden of suicide lay heavily on low- and middle-income countries. In 2015, 78% of all known suicides occurred in these countries, and suicide accounted for 1.4% of all deaths worldwide, and ranked as 17th leading cause of death (WHO, 2013). Men are more likely to die of suicide than women, and this is more prominent in high-income countries with ratio of three men to every woman.

Measurement of patient satisfaction plays an important role in the health care practice to improve overall health care delivery of health care organizations, to do effective strategic decision making and monitoring of health care performance. There is a shortage of studies conducted about patient satisfaction with health system of former Soviet Union countries, as the range of patient satisfaction studies is limited mainly to countries of the USA and Europe (Footman et.al. 2013). Consequently, there is no standard scale which can be used for studies about patient satisfaction with physician-patient communication.
Aim. 1) to identify the level of patient satisfaction with physician – patient communication in outpatient care; 2) to explore factors associated with patients’ satisfaction with physician-patient communication.

Postpartum depression (PPD) is recognized as the major public psychological health issue that affects 13% of women at postnatal period worldwide (O’Hara and Swain, 1996). Currently, there is a lack of information about the state of PPD in Kazakhstan, Central Asian country with population of 17.8 million. To bridge this gap, PPD prevalence and risk factors among women in Astana, the capital of Kazakhstan, were evaluated.

The following study analyzed factors affecting profitability of medical state enterprises. The primary interest of the study was the effect of corporate governance on financial performance of oblast level hospitals and primary care clinics. It was found that the presence of a supervisory board for the hospital or clinic is associated with decreased probability of producing net positive income (37% less chance) in these organizations. Also it was found that characteristics of supervisory boards like number of people in the board and meetings held by supervisory boards are not associated with profitability of state medical enterprises. The profitability of state medical organizations also differed between regions of the country and between organizations located in cities and rural regions.

Nutritional and behavioral risk factors for gastritis in Kazakhstani population: preliminary results.
RAZBEKOVA, MADINA
Gastritis
chronic gastritis
gastric cancer
stomach cancer
Gastritis is characterized as inflammation in stomach, and it can be acute and chronic. Acute gastritis can go away in several days, while chronic gastritis can persist for years. The latter is implicated with increased risk for gastric cancer. Risk factors for gastritis include H.pylori infection, family history, psychological stress, use of drugs, and lifestyle habits. Since Kazakhstan holds the fifth place among the highest stomach cancer mortality rates worldwide, epidemiology of risk factors for gastric cancer and its potential precursors are needed to study. To address this issue, lifestyle habits and family history were studied for association with chronic non-atrophic gastritis. The survey on nutrition and behavioral habits was given to patients, who underwent gastroendoscopy in two hospitals of Astana, and then further analyzed with bivariate non-parametric and bivariate logistic regression tests. Data from total of 19 gastritis patients and 14 non-gastritis patients were obtained. Though no statistical significance was found during analysis, higher frequency of alcohol drinking, kazy/shuzhyk eating, drinking piped water, having family history of cancer, and hypertension were detected in gastritis patients comparing with controls. Kumys/shubat drinking, eating fresh fruits, and overweight and obesity was less present in gastritis group than in controls. These findings supported existing knowledge on risk factors for gastritis and gave more specific evidence for chronic non-atrophic gastritis. Moreover, more research is needed on larger sample size to elucidate role of food in risk of developing chronic gastritis in people living in Kazakhstan.

Health economics analysis of mammography screening program in the Republic of Kazakhstan
Salikhanov, Islam
Breast cancer
hormonal drugs
mammography-screening
Breast cancer (hereinafter - BC) is the most frequent type of cancer among women in the Republic of Kazakhstan, accounting for almost 12% of all cases of cancers in the country [1]. Kazakhstan has the highest rates of breast cancer in the Central Asian region. Local physicians associate it with lack of breastfeeding, use of hormonal drugs, and poor ecological conditions [2]. There were 3,400 new cases of BC in Kazakhstan in 2016 [3], while number of deaths in the same year reached 1,022 [4]. The age-adjusted death rate from BC is 21.50 per 100,000, which ranks Kazakhstan 35th in the world [32]. The prevalence of BC reached 22.7 per 100,000 in 2013, and it has been increasing constantly, affecting younger population aged 25-40. It also takes the first place in mortality rates among all cancers in the 45-50-year age group. Between 1990 and 2010 the annual years of healthy life lost from breast cancer in Kazakhstan has increased by 44.0% [5]. In 1990, BC led to 38,000 years of life lost (hereinafter - YLL) in Kazakhstan. In 2010, the prevalence rate of BC has raised by 17% leading to 44,000 YLL [6].

Practice, knowledge and attitudes of physicians towards shared decision- making in their healthcare practice in the National scientific center of oncology and transplantology CF “UMC” in Astana, Kazakhstan: Pilot study
Mukhamedyarova, Meruyet
physicians
healthcare practice
Despite the importance of shared decision-making in clinical practice, it is not widely implemented in health care systems in the world, including Kazakhstan. In order to develop an effective implementation strategy for shared decision-making to be practiced in hospitals in Kazakhstan, it is necessary to identify and understand physician’s knowledge, practices, attitudes and barriers towards shared decision-making.

Epidemiology of HPV Infection and HPV-Related Cancers in Kazakhstan: a Review
Aimagambetova, Gulzhanat
Azizan, Azliyati
Human papillomavirus (HPV)
cervical cancer
HPV epidemiology
related cancers
HPV vaccination
Background: Cancer is one of the most prevalent causes of mortality worldwide. In the cervix it is considered to be caused by different high-risk human papillomavirus (HPV) types. Although many studies have already been conducted worldwide on the epidemiology of HPV infection and their oncogenic properties, limited data are available on HPV prevalence, incidence and genotype specific dissemination in Kazakhstan. Methods: To review the distribution of HPV infection, electronic databases (e.g. PubMed, Web of Science and Google Scholar) were searched for peer reviewed articles in English. The study was performed during June-July 2017 with a review of 39 relevant articles, published up to July 31, 2017. The following inclusion criteria were applied: general population data, cytology results available, and use of polymerase chain reaction (PCR) and/or Hybrid Capture® 2, Digene Corp., USA for HPV detection. Results:
As reported in limited studies, the prevalence of HPV infection in Kazakhstan ranges from 43.8% to 55.8%. However, the scenario with regard to epidemiology of HPV related cancers in Kazakhstan is not very clear. One study reported a decline of laryngeal cancer observed during the recent years, whereas cervical cancer incidence has increased to about 3000 new cervical cancer cases, and about 1,000 cervical cancer deaths each year. Conclusion: The high incidence of cervical cancer with a significant mortality rate in Kazakhstan is evidence of HPV infection abundance despite an absence of HPV screening and low public awareness of the problem. Having a well-informed understanding of the role of HPV infection could enhance the public’s acceptance of screening and intervention programs to reduce morbidity and mortality in the country due to HPV infection. Thus, the purpose of this review article is to summarize the existing
data, identifying directions for future research on HPV epidemiology and HPV-related diseases in Kazakhstan.

Viderman, Dmitriy
Khamzina, Yekaterina
Kaligozhin, Zhannur
Khudaibergenova, Makhira
Zhumadilov, Agzam
Intensive care unit (ICU)
Hospital associated infections (HAI)
Surgical site infections (SSI)
Ventilator associated pneumonia (VAP)
Blood stream infections (BSI)
Urinary tract infections (UTI)
Background: Hospital Associated infections (HAI) are very common in Intensive Care Units (ICU) and are usually associated with use of invasive devices in the patients. This study was conducted to determine the prevalence and etiological agents of HAI in a Surgical ICU in Kazakhstan, and to assess the impact of these infections on ICU stay
and mortality. Objective: To assess the rate of device-associated infections and causative HAI etiological agents in an ICU at the National Research Center for Oncology and Transplantation (NRCOT) in Astana, Kazakhstan. Methods: This retrospective, observational study was conducted in a 12-bed ICU at the NRCOT, Astana, Kazakhstan.
We enrolled all patients who were admitted to the ICU from January, 2014 through November 2015, aged 18 to 90 years of age who developed an HAI. Results: The most common type of HAI was surgical site infection (SSI), followed by ventilator-associated
pneumonia (VAP), catheter-related blood stream infection (BSI) and catheter-associated urinary tract infection (UTI). The most common HAI was SSI with Pseudomonas aeruginosa as the most common etiological agent. The second most common HAI was VAP also with P. aeruginosa followed by BSI which was also associated
with P. aeruginosa (in 2014) and Enterococcus faecalis, and Klebsiella pneumoniae (in 2015) as the most common etiological agents causing these infections.
