Öğe Acute physiological changes in elite free-style wrestlers during a one-day tournament(Edizioni Minerva Medica, 2016) Kafkas, Muhammed E.; Taskiran, Celal; Kafkas, Armagan Sahin; Ozen, Gokmen; Taskapan, Cagatay; Ozyalin, Fatma; Skarpanska-Stejnborn, AnnaBACKGROUND: The purpose of this study was to examine tree radical production, muscle damage and inflammation responses of well-trained wrestlers to a simulated one-day tournament of free-style wrestling. METHODS: Twelve elite competitive wrestlers with mean age (+/- SD) of 24.09 +/- 6.20 years, body mass 74.09 +/- 11.50 kg, and body height 174.90 +/- 8.8 cm and who had competed for national teams completed five matches according to the official Olympic wrestling tournament regulations. Blood sampling was collected before and after fifth match. Baseline blood testing was measured at 16:00 a.m. and then matches started at 12:00. Each match was implemented within one hour. Also, the resting time was 45 minutes following each match. The measurements were analyzed by Wilcoxon Signed Ranks Test, which is used to test for significant differences between pre- and post-test. RESULTS: The post-match lactate dehydrogenase creatine kinase (CK), and interleukin (IL)-6 levels were significantly increased compared with the baseline status. However. baseline malondialdehyde levels were not found significantly different compared with post-match. CONCLUSIONS: The current study ensured that one-day Free-Style wrestling tournament brings about significantly increasing on CK, LDH of muscle damage markers. Also, inflammatory status showed a progressive worsening during the course of one-day tournament. The study showed enhanced muscle damage markers and inflammatory status after one-day Free-Style wrestling tournament. Therefore, it appears that one-day free-style wrestling tournament imposes significant physiological demands on wrestlers that may adversely affect their performance and inflammatory status, thereby putting the athletes in a greater risk for injury.Öğe Alteration in Bone Metabolism Markers Fallowing 3-Months Insulin Therapy in Patients with Type 2 Diabetes Mellitus: Analogues Vs. Human Insulins(Endocrine Soc, 2014) Sahin, Ibrahim; Karaca, Zuhal; Taskapan, Cagatay; Ozyalin, Fatma; Yologlu, Saim[Abstract Not Available]Öğe Association of folic acid receptor ? in maternal serum with neural tube defects(Informa Healthcare, 2014) Celik, Ebru; Karaer, Abdullah; Turkcuoglu, Ilgin; Turhan, Ugur; Gungoren, Arif; Taskapan, Cagatay; Ozyalin, FatmaObjective: To evaluate whether serum folic receptor alpha levels are changed in women whose previous pregnancies were complicated with neural tube defects (NTDs). Methods: This was a case-control study that included 41 women as the control group who had previously had at least one healthy pregnancy and 37 women as the study group who had a previous pregnancy complicated with NTDs. Blood samples were obtained from all of the participants six weeks after the termination of pregnancy or delivery of a baby. Serum folate receptor alpha concentrations were analyzed using a commercially available enzyme-linked immunosorbent assay (ELISA) kit. Results: The mean concentrations of serum folate receptor alpha were significantly lower in the NTD cases compared to those in the control group (p = 0.02). There was no significant difference in mean serum folate titers between the NTD cases and the control group (p = 0.07). Conclusion: Low serum folic acid receptor alpha levels in the current study did not appear to be a regulatory marker of maternal folate homeostasis per se but rather a factor that contributed to the development of NTDs.Öğe Diabetic muscle infraction: An unusual cause of muscle pain in a diabetic patient on hemodialysis(Springer, 2005) Sahin, Ibrahim; Taskapan, Cagatay; Taskapan, Hulya; Baysal, Tamer; Bentli, Recep; Tekes, Selda; Kosar, FeridunDiabetic muscle infarction (DMI) is a rare, painful and potentially serious complication in patients with poorly controlled diabetes mellitus and frequently misdiagnosed clinically as abscess, neoplasm, or myositis. A 36-year-old diabetic woman referred to our clinic with severe pain in the left anteromedial thigh. She had a 15-year history of Type 2 diabetes mellitus (DM). She was complicated by diabetic nephropathy and requiring hemodialysis. She had first noticed pain and swelling in her left thigh after a minimal trauma for 2 days prior to presentation. Clinical and laboratory evaluation, and muscle biopsy revealed the diagnosis of muscle infarctions. She did no respond to the conservative therapy. Pain and swelling in her thigh worsened progressively. She underwent surgical debridment and then, her clinical status improved. We describe the characteristic clinical and pathologic findings and the course of the illness with emphasis on the importance of recognition of the syndrome so that unnecessary investigation and overzealous therapy can be avoided.Öğe The effects of total parenteral nutrition on telomerase expression in rabbit(2018) Gurunluoglu, Kubilay; Bayrakci, Ercan; Gokce, Hasan; Kocbiyik, Alper; Taskapan, Cagatay; Tasci, Aytac; Aksungur, Zeynep; Arslan, Ahmet Kadir; Demircan, MehmetAbstract Aim: Total parenteral nutrition (TPN) is a technique which is use to give vitally mandatory substances in to the venous compartments whenever the gastrointestinal system cannot be used by the patients. Telomerase catalyzes DNA synthesis, which is necessary to maintain telomere length and stabilize the genome to allow continued cell proliferation. In this study, we explored the effects of TPN administration on telomerase reverse transcriptase (TERT) expression in various tissue and serum telomerase level. Material and Methods: In this study a number of 42 same-aged albino, equal number of male and female, new zealand rabbits were use, divided in to three groups. Group 1 rabbits received TPN for 10 days via a central venous catheter. Group 2 received 50 mL/ kg/day physiological saline via a central venous catheter. Group 3 served as the control group. The rabbits were sacrificed after 10 days, and serum telomerase levels were measured by enzyme-linked immunosorbent assay. TERT expression in gonadal, liver, jejunum, and skin tissues were determined immunohistochemically. Blood samples were obtained before and after TPN and saline administration in the TPN and serum saline groups, respectively, and at the end of the experiment in the control group. Results: Telomerase expression in liver, gonads and serum level of TPN group was significantly higher than control and serum saline groups. Conclusion: TPN may be a positive effect in liver and gonadal telomer kinetic. However, we think that TPN increases DNA damage throughout the body.Öğe Evaluation by N-terminal Prohormone of Brain Natriuretic Peptide Concentrations and Ross Scoring of the Efficacy of Digoxin in the Treatment of Heart Failure Secondary to Congenital Heart Disease With Left-to-Right Shunts(Springer, 2013) Elkiran, Ozlem; Sandikkaya, Ayse; Kocak, Gulendam; Karakurt, Cemsit; Taskapan, Cagatay; Yologlu, SaimThis study aimed to evaluate the effectiveness of digoxin in children with heart failure secondary to left-to-right shunt lesions and normal left ventricular systolic function. The study registered 37 such patients (ages 10 days to 24 months, groups 1 and 2) and used 20 healthy children as a control group (group 3). Left ventricular systolic function, as assessed by conventional echocardiography, was normal in all the subjects. Congestive heart failure was diagnosed by clinical evaluation and modified Ross scoring. Plasma N-terminal prohormone of brain natriuretic peptide (NT-proBNP) concentrations and complete blood counts were assessed in all the children. Group 1 was treated with digoxin, enalapril, and furosemide and group 2 with enalapril and furosemide. Approximately 1 month after starting treatment, the patients were reevaluated by physical and echocardiographic examinations, modified Ross scoring, plasma NT-proBNP concentrations, and complete blood counts. The pre- and posttreatment Ross scores of group 1 (p = 0.377) and group 2 (p = 0.616) did not differ significantly. The NT-proBNP values in both groups decreased after treatment (p = 0.0001). The pre- and posttreatment NT-proBNP values did not differ significantly in group 1 (p = 0.094)) and group 2 (p = 0.372). The pretreatment NT-proBNP values in groups 1 and 2 (p = 0.0001) were significantly higher than in the control group (p = 0.003). A smaller difference was observed between posttreatment NT-proBNP values in group 1 and the control group (p = 0.045). We found no significant difference between the posttreatment NT-proBNP values of group 2 and those of the control group (p = 0.271). The study showed that both treatments currently used to treat heart failure secondary to congenital heart disease with left-to-right shunts and preserved left ventricular systolic function are effective and do not differ significantly. Thus, digoxin does not provide any extra benefit in the treatment of such patients.Öğe An experimental rat model of electric shock injury with isolated electric shock and water conduction: the histopathological changes on the skin and internal organs and the effect on biochemical parameters(Springer, 2023) Dundar, Ahmet Sedat; Oruc, Mucahit; Celbis, Osman; Samdanci, Emine Turkmen; Akatli, Ayse Nur; Okumus, Hasan; Taskapan, CagatayIt is difficult to determine the cause of death in electric shock injuries when no trace can be determined on the skin, and this is accepted as a reason for negative autopsy. We aimed to determine useful parameters in the definition of the cause of deaths associated with electric shock and particularly those formed with water conduction. This study used a total of 42 rats, applied with fatal electric shock formed of isolated electric shock at 220 V and with water conduction. The serum NT-ProBNP and H-FABP levels were examined together with histopathological changes in the brain, cerebellum, brainstem, heart, liver and skin and the Bax, caspase-3 and HSP-60 antibody status in these tissues. A statistically significant difference was determined between the groups in respect of the serum H-FABP values and the immunohistochemical staining of the samples taken from the organs. In conclusion, this study is the first in literature with an experimental model of electric shock with water conduction. Using immunohistochemical and biochemical markers in deaths associated with isolated electric shock and electric shock with water conduction, the results of this study can contribute to the clarification of one of the reasons for negative autopsy in forensic medicine.Öğe Impact of Serum and Follicular Vitamin D Levels on Assisted Reproductive Techniques Outcome(Sci Printers & Publ Inc, 2018) Tuncay, Gorkem; Taskapan, CagatayOBJECTIVE: To compare vitamin D levels in the serum and follicular fluids of in vitro fertilization (IVF) patients with regard to their pregnancy outcomes. STUDY DESIGN: This study enrolled 170 female patients (20-44 years old) who underwent intracytoplasmic sperm injection (ICSI) cycles between February 2015 and February 2016. The serum vitamin D was isolated by centrifugation. The follicular fluid samples were centrifuged and the supernatant was evaluated after the oocyte puncture procedure. RESULTS: Fifty-six patients had clinical pregnancies and 106 did not, and we did not find any statistically significant differences between these 2 groups in their basic or cycle characteristics. The basal follicle-stimulating hormone level was significantly lower in the pregnant group (p=0.003). A significant difference was detected in the serum vitamin D, and the follicular vitamin D concentrations were higher in the pregnant group (p=0.01 and p=0.003, respectively). There was a significant linear correlation between the 25-hydroxy vitamin D levels in the serum and follicular fluid (r=0.77, p<0.001). CONCLUSION: High vitamin D levels can improve the implantation rate and IVF outcome. The serum vitamin D level should be determined prior to IVF/ICSI cycles and supplemented if an insufficiency is established.Öğe Independent predictors of cardiovascular risk in polycystic ovarian syndrome(Taylor & Francis Ltd, 2011) Turkcuoglu, Ilgin; Kafkasli, Ayse; Meydanli, Mehmet Mutlu; Ozyalin, Fatma; Taskapan, CagatayWe aimed to determine the independent predictors of cardiovascular risk in polycystic ovarian syndrome (PCOS). Ninety-one PCOS and 51 control patients were enrolled to our prospective cross sectional case-control study. In early follicular phase hormonal and lipid profile, fasting insulin and CRP (hs-CRP) levels and glucose levels on fasting and 2 h after the 75 g glucose intake were determined. Insulin resistance (IR) was evaluated with homeostasis model assessment and free testosterone was determined with free androgen index. PCOS was found to be associated with dyslipidemia, hyperandrogenism, IR and sub-clinical inflammation. The prevalence of overweight-obesity (41.8% vs. 25.5%, p = 0.038), IR (42.9% vs. 23.5%, p = 0.035) and glucose intolerance (15.38% vs. 1.96%, p = 0.043) were significantly higher in PCOS compared to control group. Independent predictors of the risk of elevated hs-CRP level were PCOS status (OR = 5, 95% CI: 1.55-16.14, p = 0.007) and high BMI (OR = 4.2, 95% CI: 1.2-14.2, p = 0.022) and high BMI (OR = 1.2, 95% CI: 1.05-1.4, p = 0.007) and of TC/HDL ratio was high BMI (OR = 1.21, 95% CI: 1.05-1.4, p = 0.009) and increasing age (OR = 1.11, 95% CI: 1.01-1.2, p = 0.04). The presence of PCOS, independent from obesity and IR, is the strongest predictor of elevated hs-CRP level. Obesity and advanced age further increases the cardiovascular risk in PCOS.Öğe The investigation of serum levels of ADAMTS 5 and 8 (the A disintegrin and metalloproteinase with thrombospondin motifs) in the etiology of endometrial cancer(Taylor & Francis Inc, 2020) Yilmaz, Ercan; Melekoglu, Rauf; Taskapan, Cagatay; Budak, Fatma Olmez; Toprak, SerhatThe aim of this study was to investigate the serum levels of the A disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) 5 and 8 in patients diagnosed with endometrial cancer. Our study included 41 patients diagnosed with endometrial cancer. The control group consisted of 41 patients diagnosed with benign endometrial pathology. The serum samples were centrifuged and stored at -80 degrees C. The serum levels of ADAMTS were significantly higher (p<.001), whereas the levels of ADAMTS 8 were significantly lower in patients diagnosed with cancer (p<.001). In addition to the presence of known factors in the aetiology of endometrial cancer, the effect of inflammatory factors and some new proteins has centred on the causes of tumourigenesis in recent years. In this sense, these proteins, called the ADAMTS, are the source of new studies.Impact Statement What is already known on this subject? When the recent studies about endometrial cancer are evaluated, it is seen that the effects of chronic inflammation and cytokines have gained importance in its aetiology. The A disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) gene family consist of 19 proteases that play essential role in the formation of the extracellular matrix (ECM) and interact with inflammatory cytokines. These proteases and their substrates provide a wide range of functions in different tissues, including ECM remodelling, angiogenesis, fibrosis and coagulation. What the results of this study add? ADAMTS 5, which causes the degradation of the ECM with Aggrecanase activity, was found to be significantly higher in patients diagnosed with cancer and ADAMTS 8 with anti-angiogenesis activity was significantly lower in patients diagnosed with endometrial cancer.Öğe Metabolic and carbohydrate characteristics of different phenotypes of polycystic ovary syndrome(Aves, 2016) Celik, Ebru; Turkcuoglu, Ilgin; Ata, Baris; Karaer, Abdullah; Kirici, Pinar; Eraslan, Sevil; Taskapan, CagatayObjective: To compare the prevalence of various metabolic and cardiovascular risk factors and insulin resistance between polycystic ovary syndrome (PCOS) patients with or without hyperandrogenism. Material and Methods: This is a retrospective cross-sectional study involving women with PCOS as diagnosed according to the Androgen Excess (AE) Society definition (n=504) and women with normoandrogenemic PCOS (n=183). Anthropometrics, lipid profile, glucose, insulin, oral glucose tolerance test (OGTT), and reproductive hormone levels were evaluated. Results: Women with PCOS diagnosed according to the AE Society had a significantly higher prevalence of metabolic syndrome compared with the normoandrogenemic PCOS phenotype: odds ratio (OR) 2.95 [95% confidence interval (CI) 1.21-7.21]. There was no significant difference in the prevalence glucose intolerance test between the groups [OR: 2.15, 95% CI 0.71-6.56]. The prevalence of low high density lipoprotein (HDL)-cholesterol in the group under the AE-PCOS Society criteria was higher than that of the normoandrogenemic PCOS group [OR: 2.82, 95% CI 1.29-3.36]. Conclusion: The risks of metabolic syndrome and cardiovascular disease may vary among the phenotypes of PCOS based on the Rotterdam criteria. This new data may be of reference in informing women with PCOS, although further prospective studies are needed to validate this proposition.Öğe The Second and Third Hemoglobin Kansas Cases in the Turkish Population(Galenos Yayincilik, 2017) Tanriverdi, Zeynep Kayra; Akyay, Arzu; Sen, Askin; Taskapan, Cagatay; Ozgen, Unsal[Abstract Not Available]Öğe Serum IL-1, IL-2, IL-4, IL-6, IL-10, TNF-?, and IFN-? levels in drug-free, comorbidity-free obsessive-compulsive disorder patients(Cumhuriyet Univ Tip Fak Psikiyatri Anabilim Dali, 2018) Erbay, Lale Gonenir; Akti Kavuran, Nursel; Taskapan, Cagatay; Ince, Lara Utku; Yologlu, Saim; Temelli, Husniye Gul; Unal, SuheylaObjective: Increasing evidence suggests that certain inflammatory factors, especially cytokines, can lead to neurochemical and behavioural changes via their role in the brain signalling system. Studies investigating cytokine abnormalities in obsessive-compulsive disorder (OCD) have yielded conflicting results thus far. The aim of this study was to investigate the serum IL-1, IL-4, IL-6, IL-10, TNF-alpha, and IFN-gamma levels in drug-free, comorbidity-free patients with OCD. Methods: Forty comorbidity-free, drug-free OCD patients and 40 age-and sex-matched healthy volunteers were included in the study. Clinical severity was assessed using the Yale-Brown Obsessive-Compulsive Evaluation Scale (YBOCES). Results: IL-1 levels were significantly higher and IL-2, IL-6, and TNF-alpha levels were significantly lower in patients than in controls. No differences were observed in IL-4, IL-10, and IFN-gamma levels. However, a negative relationship was found between IL-1 levels and compulsive symptoms (YBOCES) in OCD patients. Conclusions: Our findings suggest the possible role of cytokines in the pathogenesis of OCD. It is important to continue investigating the role of cytokines and other immunological markers in both the etiology and treatment of OCD.Öğe Serum Nickel and Titanium Levels after Transcatheter Closure of Atrial Septal Defects with Amplatzer Septal Occluder(Hindawi Ltd, 2019) Elkiran, Ozlem; Karakurt, Cemsit; Kocak, Gulendam; Taskapan, CagatayIntroduction. There is a concern about release of nickel and titanium after implantation of nitinol-containing devices. Objective. To evaluate serum nickel and titanium release after implantation of Amplatzer occluder. Materials and methods. In 38 pediatric patients with no history of nickel sensitivity, blood samples were drawn 24 hours before and 24 hours, 1, 3, 6, and 12 months after implantation. Nickel and titanium concentrations were measured by atomic absorption spectrophotometry. Results. The median serum nickel level which was 0.44ng/mL before the implantation increased to 1.01ng/mL 24 hours after implantation and 1.72ng/mL one month after implantation. The maximum level was detected 3 months after implantation, with a median level of 1.96ng/mL. During follow-up, the nickel levels decreased to those measured before implantation. Serum nickel levels at the 24th hour, 1st month, and 3rd month following implantation were found to have increased significantly. No patients showed a detectable serum titanium level. Discussion. This is the first study that evaluated both serum nickel and titanium release after implantation of the Amplatzer occluder. Our study shows that nickel is released from the device in the first few months after implantation. Therefore, in patients with nickel allergy, other devices may be considered.Öğe SERUM NT-PROBNP, ACYLGHRELIN, DESACYLGHRELIN, OBESTATIN, AND FATTY ACID BINDING PROTEIN 4 LEVELS IN HEMODIALYSIS PATIENT(Oxford Univ Press, 2017) Taskapan, Hulya; Taskapan, Cagatay; Ozyalin, Fatma; Dogan, Ali[Abstract Not Available]Öğe Serum Pentraxin 3 and hs-CRP Levels in Children with Severe Pulmonary Hypertension(Galenos Publ House, 2014) Karakurt, Cemsit; Baspinar, Osman; Celik, Fazli Serkan; Taskapan, Cagatay; Sahin, Aydin Derya; Yologlu, SaimBackground: Pulmonary arterial hypertension secondary to untreated left-to-right shunt defects leads to increased pulmonary blood flow, endothelial dysfunction, increased pulmonary vascular resistance, vascular remodelling, neointimal and plexiform lesions. Some recent studies have shown that inflammation has an important role in the pathophysiology of pulmonary arterial hypertension. Aims: The aim of this study is to evaluate serum pentraxin 3 and high sensitive (hs)-C reactive protein (hs-CRP) levels in children with severe pulmonary arterial hypertension (PAH) secondary to untreated congenital heart defects and evaluate the role of inflammation in pulmonary hypertension. Study Design: Cross sectional study. Methods: After ethics committee approval and receiving consent from parents, there were 31 children were selected for the study with severe PAH, mostly with a left-to-right shunt, who had been assessed by cardiac catheterisation and were taking specific pulmonary vasodilators. The control group consisted of 39 age and gender matched healthy children. After recording data about all the patients including age, gender, weight, haemodynamic studies and vasodilator testing, a physical examination was done for all subjects. Blood was taken from patients and the control group using peripheral veins to analyse serum Pentraxin 3, N-terminal pro-Brain Natriuretic Pep-tide (NT-ProBNP) and hs-CRP levels. Serum Pentraxin-3 levels were measured by enzyme linked immunosorbent assay (ELISA) and expressed as ng/mL. Serum hs-CRP levels were measured with an immunonephelometric method and expressed as mg/dL. The serum concentration of NT-proBNP was determined by a chemiluminescent immunumetric assay and expressed as pg/mL. Results: Serum Pentraxin-3 levels were determined to be 1.28 +/- 2.12 (0.12-11.43) in the PAH group (group 1) and 0.40 +/- 0.72 (0.07-3.45) in group 2. There was a statistically significant difference between the two groups (p<0.01). Serum hs-CRP levels were measured as 2.92 +/- 2.12 (0.32-14.7) mg/dL in group 1 and 0.35 +/- 0.16 (0.07-3.45) mg/dL in group 2. The hs-CRP level was increased in the PAH group to a significant degree (p<0.01). Conclusion: Our study showed that pentraxin 3 and hs-CRP levels were increased significantly in the PAH group. We consider that inflammation plays an important role in severe pulmonary hypertension and progressive pulmonary arterial hypertension in children with PAH.
