Item Metadata only 5 Patient specific in situ 3D printing(Woodhead Publishing, 2017-01-01) Akilbekova, Dana; Mektepbayeva, Damel; Dana, AkilbekovaAbstract In this chapter, we will focus on how 3D printer technology is transforming traditional medicine into a personalized approach, giving an overview of the technology advancement and its clinical applications. First, we will discuss why personalization in medicine is required, its benefits for the patients and how 3D printing technology can address this need for the patient specific treatment solutions. Basic capabilities of 3D printers and the three most common 3D printing technologies used in medical applications will be covered as well. The second section focuses on current and potential medical applications of 3D printing. The main medical applications can be arranged into three categories: (1) 3D bioprinting of organs and tissues; (2) patient specific medical devices: prosthetics and implants; and (3) 3D models for surgical preparation. Here, we will discuss 3D printing of living cells, in situ 3D bioprinting directly to the defect site, some successful cases of the implantation of various 3D constructs and the production of precise anatomical models for surgical trainings. Lastly, we will highlight challenges and emerging technology developments for the printing of functional organ constructs and medical devices.Item Open Access Accumulated substancies and calorific capacity in adipose tissue: Physical and chemical clinical trial(BBA Clinical, 2017-05-30) Oshakbayev, Kuat; Dukenbayeva, Bibazhar; Togizbayeva, Gulnar; Gazaliyeva, Meruyert; Syzdykova, Alma; Daurenbekov, Kanat; Issa, PernekulAim: To study physical and chemical structures and properties including calorific value of human adipose tissue in different anatomical location in autopsy-assigned clinical trial. Methods: A pilot physical and chemical descriptive randomized autopsy-assigned trial. Adipose tissue 252 sampled from 36 individuals at autopsy who between 36 and 63 years old died from road accidents. Interventions: Chemical functional groups and calorific value were studied using infrared and atomic adsorptive spectrometries, elemental chemical analysis and differential scanning calorimetry. Adipose tissue was sampled from the 7 various anatomical locations. Results: The highest levels of the analysed chemical substancies were found in dense atherosclerotic plaque. Dense atherosclerotic plaque contains the most of metabolic products, organic and inorganic elements. Dense atherosclerotic plaque has the most of calorific value. The lowest calorific capacity has a pararenal fat. Conclusions: Human body lipids serve as a harbor for various organic substances, they may absorb different metabolic products, and they have different calorific capacity depending on their location and forms. Atherosclerotic plaque contains the most of organic and inorganic elements, and brings the highest energy potential.Item Open Access Accumulated substancies and calorific capacity in adipose tissue: Physical and chemical clinical trial(2017-12-01) Oshakbayev, Kuat; Dukenbayeva, Bibazhar; Togizbayeva, Gulnar; Gazaliyeva, Meruyert; Syzdykova, Alma; Daurenbekov, Kanat; Issa, Pernekul; Kuat, OshakbayevAbstract AimTo study physical and chemical structures and properties including calorific value of human adipose tissue in different anatomical location in autopsy-assigned clinical trial.

Since July 2014, a Clinical Department with 69 beds was arranged, and National Research Center for Oncology and Transplantation SC was arranged. From 2010 to 2016, the modalities of hematopoietic stem cell transplantation have been advanced, from autologous BMT to allogeneic hematopoietic stem cell transplants (HSCT) from matched donors (33%), and haploidentical HSCTs (43% in 2016), a total of 186 transpants. Bone marrow was used as a source of stem cells in 71 cases (71 donors for allo-HSCT in 69 recipients), whereas peripheral stem cells were harvested in 73 cases (15 donors for 15 recipients of allo-BMT, and 58 marrow harvests for autologous BMT).Item Open Access BASOPHILS AND SYSTEMIC LUPUS ERYTHEMATOSUS IN MURINE MODELS AND HUMAN PATIENTS(Biology, 2020-09-23) Dossybayeva, Kuanysh; Abdukhakimova, Diyora; Poddighe, DimitriBasophils are the rarest cell population in the blood. Even though basophils are known to participate in some allergic reactions and immune responses to parasitic infections, their immunological role is still largely elusive. Recent evidence has suggested that in some murine models of systemic lupus erythematosus and lupus-like nephritis, basophils may also be implicated in autoimmunity processes by promoting autoantibody production and tissue injury. We conducted a systematic search to collect the available evidence on basophils’ potential immunomodulatory role in autoimmunity and, particularly, systemic lupus erythematosus. We identified several articles investigating basophils’ role in murine models of lupus (n = 3) and in patients affected with systemic lupus erythematosus (n = 8). Even though the alteration of the “adaptive” immune response is considered the main immunopathological event in systemic lupus erythematosus, the contribution from the mechanisms of “innate” immunity and, particularly, basophils may be relevant as well, by modulating the activation, polarization, and survival of lymphocytesItem Open Access Cравнительный анализ особенностей развития вторых опухолей после лучевой терапии и химиолучевой терапии первой опухоли(2015) Важенин, А.В.; Шаназаров, Н.А.; Шунько, Е.Л.В настоящее время индуцированные лечением первично-множественные злокачественные новообразования являются одной из основных причин смертности онкологических больных после проведенного лучевого и химиолучевого лечения. Целью нашего исследования является сравнительный анализ особенностей развития первично-множественных метахронных опухолей после лучевой и химиолучевой терапии первой опухоли. Мы выделили группу из 232 больных, у которых впоследствии после лучевой терапии первой опухоли возникли первично-множественные метахронные опухоли (1 группа) и группу из 42 больных, у которых впоследствии после химиолучевой терапии первой опухоли возникли первично-множественные метахронные опухоли (2 группа). Для больных, пролеченных лучевой терапией, характерны: более старший возраст, более длительные интервалы времени от появления первой опухоли до появления второй опухоли, от начала терапии первой опухоли до появления второй опухоли и от начала лучевой терапии первой опухоли до появления второй опухоли. Аналогичная тенденция сохраняется и при соответствующем сравнении подгрупп больных 1 и 2 группы (с мультицентрическими метахронными множественными опухолями в одном органе, с системными опухолями и опухолями парных органов, несистемными множественными опухолями различных органов).Item Open Access The effect of intraumbilical fetal nutrition via a subcutaneously implanted port system on amino acid concentration by severe IUGR human fetuses(J Perinat Med., 2017) Tchirikov, Michael; Zhumadilov, Zhaxybay; Bapayeva, Gauri; Bergner, Michael; Entezami, MichaelObjective: To determine if intrauterine intraumbilical supplementation with amino acids (AA) and glucose can improve neonatal outcome of severe growth restricted human fetuses (IUGR). Methods: Prospective pilot study of intrauterine treatment of severe IUGR fetuses [n = 14, 27 weeks of gestation (range 23–31)] with erebroplacental ratio < 1, with longterm intraumbilical AA and glucose supplementation (10% of feto-placental blood volume/day) using a perinatal port system alone (n = 5) or combined with hyperbaric oxygenation (n = 1, HBO) vs. control group (n = 8).Item Open Access Embolization of the prostatic arteries in BPH patients is relatively safe and effective treatment and an alternative for surgical treatment in patients with high operating and anesthetic risk.(UMC “National Scientific center for Oncology and transplantation”, 2018) Tabymbaev, N.B; Baizhanuly, K.B.; Zhumagazin, ZH.D.Benign prostatic hyperplasia (BPH) is one of the most common diseases in older men age. In the course of the trial treatment of such pathology is impossible due to a number of objective reasons, such as age and severe concomitant diseases impossible surgical methods of treatment.Item Open Access Evaluation of the modified HTK solution in pancreas transplantationdAn experimental model(Asian Journal of Surgery, 2016) Esmaeilzadeh, Majid; Fonouni, Hamidreza; Golriz, Mohammad; Majlesara, Ali; Kuttymuratov, Gani; Bergmann, Frank; Jarahian, Parvin; Khazaeipour, Zahra; Faridar, Alireza; Tahmasbi, Morva; Longerich, Thomas; Gebhard, Marta M.; Mehrabi, ArianebOne of the great challenges in pancreas transplantation is the ischemia reperfusion injury. It is mentioned that free oxygen and/or nitrogen radicals play a prominent role in this phase. To minimize this problem, a modified histidineetryptophan eketoglutarate (HTK) solution that contains modified antioxidants has been developed. Our aim was to evaluate this solution in improving the viability of the pancreas in comparison with standard HTK and University of Wisconsin (UW) solutions in a porcine model of pancreas transplantation.Item Open Access The expanding Therapeutic Perspective of CCR5 Blockade(Frontiers in Immunology, 2018-01-12) Vangelista, Luca; Vento, SandroCCR5 and its interaction with chemokine ligands have been crucial for understanding and tackling HIV-1 entry into target cells. However, over time, CCR5 has witnessed an impressive transition from being considered rather unimportant in physiology and pathology to becoming central in a growing number of pathophysiological conditions. It now turns out that the massive efforts devoted to combat HIV-1 entry by interfering with CCR5, and the subsequent production of chemokine ligand variants, small chemical compounds, and other molecular entities and strategies, may set the therapeutic standards for a wealth of different pathologies. Expressed on various cell types, CCR5 plays a vital role in the inflammatory response by directing cells to sites of inflammation. Aside HIV-1, CCR5 has been implicated in other infectious diseases and non-infectious diseases such as cancer, atherosclerosis, and inflammatory bowel disease. Individuals carrying the CCR5Δ32 mutation live a normal life and are warranted a natural barrier to HIV-1 infection. Therefore, CCR5 antagonism and gene-edited knockout of the receptor gained growing interest for the therapeutic role that CCR5 blockade may play in the attenuation of the severity or progression of numerous diseases.Item Open Access Fast detection of deletion breakpoints using quantitative PCR(Genetics and Molecular Biology, 2016) Abildinova, Gulshara; Abdrakhmanova, Zhanara; Tuchinsky, Helena; Nesher, Elimelech; Pinhasov, Albert; Raskin, LeonThe routine detection of large and medium copy number variants (CNVs) is well established. Hemizygotic deletions or duplications in the large Duchenne muscular dystrophyDMD gene responsible for Duchenne and Becker muscular dystrophies are routinely identified using multiple ligation probe amplification and array-based comparative genomic hybridization. These methods only map deleted or duplicated exons, without providing the exact location of breakpoints. Commonly used methods for the detection of CNV breakpoints include long-range PCR and primer walking, their success being limited by the deletion size, GC content and presence of DNA repeats. Here, we present a strategy for detecting the breakpoints of medium and large CNVs regardless of their size. The hemizygous deletion of exons 45-50 in the DMD gene and the large autosomal heterozygous PARK2 deletion were used to demonstrate the workflow that relies on real-time quantitative PCR to narrow down the deletion region and Sanger sequencing for breakpoint confirmation. The strategy is fast, reliable and cost-efficient, making it amenable to widespread use in genetic laboratories.Item Open Access FERTILITY PRESERVATION IN ENDOMETRIAL CANCER PATIENTS: OPTIONS, CHALLENGES AND PERSPECTIVES(Ecancermedicalscience, 2020-05) Terzic, Milan; Norton, Melanie; Terzic, Sanja; Bapayeva, Gauri; Aimagambetova, GulzhanatSeveral different approaches have been designed by physicians in order to preserve fertility in younger patients with endometrial carcinoma. There are various options offering different advantages, but hysteroscopic resection of pathologic endometrial tissue with placement of a Levonorgestrel Intrauterine Device has proven to be the most successful in allowing patients to conceive and give birth afterwards. However, conservative treatments should only be considered in patients with low-grade and low-stage endometrial tumours. There are many published studies which have sought out a preferable approach to treating endometrial cancer whilst preserving fertility. However, more research on this matter is needed to allow a better understanding as to which techniques/approaches are optimal. In this review, we will summarise the current available treatment options for endometrial cancer in patients of reproductive age.Item Open Access Five-year analysis of the treatment of varicose transformation of the great saphenous vein(UMC. National Research Center for Oncology, 2018-10) Sultanaliev, T. A.; Sagandykov, I .N.; Parmanov, A. T.; Chinaliyev, A. M.The widely used treatment options for varicose transformation of the great saphenous vein in Kazakhstan are: cross-surgery (Troyanova-Trendelenburg surgery), safenectomy, endovenous thermal ablation (EVTA), foam sclerotherapy. In this article, based on extensive experience, we reviewed the results of early and late postoperative complications in patients with varicose pathology of the great saphenous vein who were hospitalized in our clinic.Item Open Access Gastric greater curvature plication combined with Nissen fundoplication in the treatment of gastroesophageal reflux disease and obesity(Medicina, 2016) Ospanov, Oral; Maleckas, Almantas; Orekeshova, AkzhunusBackground and aim: Established anti-reflux procedures such as fundoplications are less efficient in obese patients. The aim of this study was to investigate clinical effectiveness of the fundoplication combined with gastric greater curvature plication in the treatment of gastroesophageal reflux disease (GERD) in obese patients. Materials and methods: During the period from June 2010 to September 2014, patients operated for GERD with BMI from 30 to 39.9 kg/m2 were included into the prospective study. Laparoscopic Nissen fundoplication (LNF, n = 58) was performed until February 2013 and later laparoscopic Nissen fundoplication was combined with gastric greater curvature plication (LNFGP, n = 56). The groups were compared according to the control of GERD and weight loss. Results: In LNF group there were significantly more males, patients had lower BMI and longer duration of GERD symptoms. Duration of surgery was significantly longer in LNFGP group, 96.5 (17.3) min vs. 59.8 (16.1) min (P < 0.0001). Postoperative morbidity was similar, 3.6% and 3.4% in LNFGP and LNF groups, respectively (P = 0.9539). The average percentage of excess BMI loss after 12 months was 45.3 (5.8) in LNFGP group as compared to 18.4 (4.6) in LNF group (P < 0.0001). Significantly more patients experienced remission or improvement of type 2 diabetes mellitus (P = 0.03) and hypercholesterolemia (P = 0.0001) in LNFGP group. No significant differences between the groups in postoperative DeMeester score, GERD-HRQL mean score, overall satisfaction and healing of esophagitis were observed.Item Open Access Hyperbaric oxygenation and glucose/amino acids substitution in human severe placental insufficiency(Wiley Open Access, 2018-03-13) Tchirikov, Michael; Saling, Erich; Bapayeva, Gauri; Bucher, Michael; Thews, Oliver; Seliger, GregorIn the first case, the AA and glucose were infused through a perinatal port system into the umbilical vein at 30 weeks' gestation due to severe IUGR. The patient received daily hyperbaric oxygenation (HBO, 100% O2) with 1.4 atmospheres absolute for 50 min for 7 days. At 31+4 weeks' gestation, the patient gave birth spontaneously to a newborn weighing 1378 g, pH 7.33, APGAR score 4/6/intubation. In follow‐up examinations at 5 years of age, the boy was doing well without any neurological disturbance or developmental delay. In the second case, the patient presented at 25/5 weeks' gestation suffering from severe IUGR received HBO and maternal AA infusions. The cardiotocography was monitored continuously during HBO treatment. The short‐time variations improved during HBO from 2.9 to 9 msec. The patient developed pathologic CTG and uterine contractions 1 day later and gave birth to a hypotrophic newborn weighing 420 g. After initial adequate stabilization, the extremely preterm newborn unfortunately died 6 days later. Fetal nutrition combined with HBO is technically possible and may allow the prolongation of the pregnancy. Fetal‐specific amino‐acid composition would facilitate the treatment options of IUGR fetuses and extremely preterm newborn.Item Open Access Infantile Osteopetrosis in a Kazakh Boy(IMAJ, 2017) Cainelli, Francesca; Tastanbekova, Venera; Nurgaliev, Dair; Lim, Natalya; Vento, SandroItem Open Access Influence of a modified preservation solution in kidney transplantation: A comparative experimental study in a porcine model(Asian Journal of Surgery, 2015) Golriz, Mohammad; Fonouni, Hamidreza; Kuttymuratov, Gani; Esmaeilzadeh, Majid; Jarahian, Parvin; Longerich, Thomas; Tahmasbi, Morva; Faridar, Alireza; Abbasi, Sepehr; Mehrabi, Arianeb; Gebhard, Marta M.Currently, due to lack of optimal donors, more marginal organs are transplanted. Therefore, there is a high interest to ameliorate preischemic organ preservation, especially for critical donor organs. In this regard, a new histidinetryptophane ketoglutarate (HTK-N) solution has been designed and its protective efficacy was compared with the standard preservation solutionsdUniversity of Wisconsin solution and standard HTK or Custodiol (Bretschneider’s solution). Methods: Seventy-two landrace pigs were included into the study, as donors and recipients. The donor kidneys were perfused during explantation with cold University of Wisconsin solution (n Z 12), standard HTK (n Z 12), or HTK-N solutions (n Z 12), kept in the respective preservation solution at 4 C for 30 hours, implanted in the recipient pigs, and reperfused. The pigs survived in daily control for 7 days. The serum creatinine and blood urea nitrogen were assessed in pre- and postreperfusion phase on the 3rd day and 7th day posttransplantation. Additionally, tissue samples were taken to analyze the histopathological degree of tubular injury and regeneration before and after reperfusion.Item Open Access Niemann-Pick disease type C initially misdiagnosed as gaucher disease in a 6 year old kazakh girl(IMAJ, 2017) Jaxybayeva, Altynshash; Kenzhegulova, Raushan; Baygazyieva, Lyazzat; Cainelli, FrancescaItem Open Access A Rare Case of a Hydatid Cyst of the Neck in a Kazakh Boy(IMAJ, 2017-05) Suleimenova, Ardak; Utebaliyeva, Ruslan; Jenalayev, Damir; Bilal, Ruslan; Isabekova, Altynay; Vento, SandroItem Open Access Successful treatment with verapamil and oxygen for hemodialysis-related headache in a 15 year old girl(IMAJ, 2016) Khvan, Marina; Vento, Sandro
