Abstract
OBJECTIVE Obesity is an increasingly prevalent global health problem, which is generally caused by the increase in body fat mass above normal and observed in all societies. If the blood glucose level is higher than normal but not high enough to diagnose diabetes, this condition is defined as prediabetes. Adiponectin increases fatty acid oxidation and insulin sensitivity and is closely associated with obesity. One of the nuclear receptor superfamily member peroxisome proliferator-activated receptors is shown to have an important role in various metabolic reactions. This study aimed to investigate the serum levels of adiponectin and peroxisome proliferator-activated receptors-gamma parameters, which are closely related to adipose tissue, energy metabolism, and insulin sensitivity, in obese patients with and without prediabetes. METHODS For this purpose, 52 obese patients with prediabetes, 48 obese patients with non-prediabetes, and 76 healthy individuals were included in this study. Serum adiponectin and peroxisome proliferator-activated receptors-γ levels were analyzed by ELISA. RESULTS Serum adiponectin levels were significantly higher in obese patients with prediabetes (18.15±15.99) compared with the control group (15.17±15.67; p=0.42). No significant difference was observed in both adiponectin and peroxisome proliferator-activated receptors-γ levels in the obese patients with the non-prediabetes group compared with the control group. However, no significant difference was observed in the obese patients with prediabetes group and obese patients with non-prediabetes group. CONCLUSION Our results suggest that adiponectin may serve as an indicator of prediabetes. This implies that examining adiponectin levels in individuals diagnosed with prediabetes may enhance our understanding of the metabolic processes closely linked to prediabetes and related conditions.

Abstract
The course of coronavirus disease-2019 (COVID-19) differs from person to person. The relationship between the genetic variations of the host and the course of COVID-19 has been a matter of interest. In this study, we investigated whether Angiotensin-Converting Enzyme (ACE) ID, Methylenetetrahydrofolate Reductase (MTHFR) C677T, and Macrophage Migration Inhibitory Factor (MIF)-173GC variants are risk factors for the clinical course of COVID-19 disease in Turkish patients. One hundred COVID-19 patients were included in the study. The diagnosis of COVID-19 was made using Reverse Transcription Polymerase Chain Reaction (RT-PCR) and Chest Computed Tomography (CT). The patients were evaluated in 3 groups: intensive care, service, and outpatient treatment. ACE ID, MTHFR C677T, and MIF-173GC variants were genotyped by PCR-Restriction Fragment Length Polymorphism (RFLP) methods. When the genotype distribution between the groups was examined, it was found that the frequency of the ACE DD genotype and the D allele was higher in the intensive care group compared to the hospitalized and outpatient groups. MTHFR C677T CT genotype T allele and MIF-173GC, CC genotype C allele were more prevalent in the intensive care group compared to other groups. Patients with PCR-positive results had a higher MTHFR C677T C/C genotype and C allele. In CT-positive patients, the MTHFR C677T CT genotype and the MIF-173GC, G allele were more common. It is predicted that genetic predisposition may contribute to COVID-19 morbidity and mortality. Our results show that ACE ID, MTHFR C677T, and MIF-173GC variants affect the course of COVID-19 disease in the Turkish population.

Abstract
Diabetes mellitus (DM) is a serious and common in the world health problem that leads to different complications. Changes in oxidative stress and antioxidant capacity play an important role in the pathogenesis of DM. The purpose of this study was to investigate ellagic acid (EA) treatment in diabetes induced testicular damage. In our study, 24 male Sprague Dawley rats were divided into four groups. Group 1: Control (n = 6), Group 2: EA (n = 6), Group 3: Diabet (n = 6), Group 4: Diabet + EA (n = 6). Diabetes was induced by intraperitoneal injection of streptozocin (STZ) (55 mg/kg) to group 3 and 4. EA was given 100 mg/kg/day group 2 and 4 for 35 days by oral gavage. We used that Hematoxylen-Eosin (H&E) and Johnsen's scoring to determine histological change. The terminal-deoxynucleoitidyl-transferase mediated nick end-labeling assay (TUNEL) was used for apoptosis. Oxidative stress markers were determined by qRT-PCR and immunexpression of Nrf2 was evaluated in testicular tissue. In conclusion, EA administration on the diabetes model has changed the histopathological features, apopotosis and oxidative stress marker genes in the testis and may have an effect on the reduction of diabetes induced testicular damage.

Abstract
BACKGROUND Ankylosing spondylitis (AS) is a chronic inflammatory disease mainly affecting the spine and sacroiliac joints. Macrophage migration inhibitory (MIF) factor is a regulatory cytokine that inhibits random immune cell migration. MIF gene promoter polymorphisms play a role in the progression of several inflammatory disorders. AIMS To investigate the relationship between the MIF gene -173 G/C single-nucleotide polymorphism (SNP) and AS. STUDY DESIGN Cross-sectional study. METHODS In this study, a total of 161 AS and 194 normal controls were recruited. The MIF gene -173 G/C SNP was analyzed by polymerase chain reaction using the restriction fragment length polymorphism method. RESULTS There was no significant difference between groups in terms of genotype distribution (p>0.05). When wild-type G/G and G/C+C/C genotypes are compared in terms of clinical characteristics, there is a significant difference between the average age and the duration of disease in AS patients (p<0.05). CONCLUSION No significant relationship between AS disease and MIF -173 G/C polymorphism was found. MIF -173 G/C polymorphism (C allele) may affect the time of onset and the duration of disease in AS patients.

Abstract
PURPOSE Ankylosing Spondylitis (AS) is a chronic inflammatory rheumatic disease that characteristically affects the sacroiliac joints and the spine. The exact pathogenesis of AS remains poorly understood, but genetic factors play a key role in disease development. Several genes have been consistently associated with susceptibility to AS. This study was conducted in Turkish AS patients to determine the frequency of the methylenetetrahydrofolate reductase (MTHFR) gene C677T and interleukin-4 (IL-4) gene 70 bp variable number of tandem repeats (VNTR) variants, as well as their association with clinical characteristics. METHODS Genomic DNA obtained from 272 persons (122 AS patients and 150 healthy controls) was used in this study. Genomic DNA was isolated and genotyped using a polymerase chain reaction (PCR)-based restriction fragment length polymorphism (RFLP) assay for the MTHFR C677T and IL-4 70 bp VNTR gene variants, which were determined using specific PCR primers. RESULTS There was statistically significant difference between the groups with respect to MTHFR genotype distribution (p = 0.02) and allele frequencies (p < 0.001). When we examined MTHFR and IL-4 genotype frequencies according to clinical characteristics, we found an association between the homozygous MTHFR TT genotype and ocular involvement, although this did not reach statistical significance (p = 0.02). However, we did not find any difference between the groups with respect to IL-4 genotype distribution or allele frequencies and clinical characteristics (p > 0.05). CONCLUSION Our findings suggest that there is an association of the MTHFR gene C677T polymorphism with the susceptibility of a person for development of AS. However, the IL-4 gene is not associated with AS within the same population.

Abstract
CGG repeat expansion in the FMR1 gene is associated with fragile X syndrome, fragile X-associated tremor/ ataxia syndrome and fragile X-associated primary ovarian insufficiency. In this study, FMR1 gene mutation screening was carried out in 50 patients. Among them, 12 (%24) were POF and 19 (%38) were Fragile-X. We also examined the parents of the Fragile-X patients. DNA was extracted from blood with kit procedure. To examine expansion of the fragile-X CGG repeat, TP-PCR assay was performed and all amplicons were evaluated on an ABI3130XL Genetic Analyzer System by Fragman analysis. The data were analyzed by Gene Mapper Program. As a result of this study, the patients were identified with the fragile-X whose FMR1 gene CGG alleles have been observed in normal range. However, in patients who were referred with premature ovarian failure, pre-mutation frequency was observed as 6.6%. Only limited study in Turkish population reported frequency of pre-mutation carrier in POF and Fragile-X. Detection of pre-mutation carrier is important for next generation to have healthy siblings. We emphasize that TP-PCR technique is clear, reliable, sensitive, easy and fast method to detect pre-mutation. However, full mutations have to be examined by the technique of Southern blot in the diagnosis of fragile-X.

Abstract
Familial Mediterranean fever (FMF) is characterized by recurrent attacks of fever and inflammation in the peritoneum, synovium, or pleura, accompanied by pain. It is an autosomal recessive disease caused by mutations in the MEFV (MEditerranean FeVer) gene. Patients with similar genotypes exhibit phenotypic diversity. As a result, the variations in different genes could be responsible for the clinical findings of this disease. In previous studies genes encoding Angiotensin-Converting Enzyme (ACE) and IL-4 (Interleukin-4) were found to be associated with rheumatologic and autoimmune diseases. In the present study we hypothesized whether ACE I/D or IL-4 70 bp variable tandem repeats (VNTR) genes are associated with FMF and its clinical findings in Turkish patients. Genomic DNA obtained from 670 persons (339 patients with FMF and 331 healthy controls) was used in the study. Genotypes for an ACE gene I/D polymorphism and IL-4 gene 70 bp VNTR were determined by polymerase chain reaction with specific primers. To our knowledge, this is the first study examining ACE gene I/D polymorphism and IL-4 gene 70 bp VNTR polymorphism in FMF patients. As a result, there was a statistically significant difference between the groups with respect to genotype distribution (p<0.001). According to our results, ACE gene DD genotype was associated with an increased risk in FMF [p<0.001; OR (95%): 7.715 (4.503-13.22)]. When we examined ACE genotype frequencies according to the clinical characteristics, we found a statistically significant association between DD+ID genotype and fever (p=0.04). In addition IL-4 gene P1P1 genotype was associated with FMF (p<0.001). We propose that D allele or DD genotype of ACE gene and P1 allele or P1P1 genotype of IL-4 gene may be important molecular markers for susceptibility of FMF.

Abstract
Rheumatoid arthritis (RA) is a chronic, systemic inflammatory disease that mainly affects the joints. Polymorphic variations of the cytokine genes and MTHFR gene have received attention as potential markers of susceptibility, severity, and/or protection in RA. The aim of this study was to investigate the MTHFR C677T and IL-4 70bp VNTR variation in Turkish patients with RA and evaluate if there was an association with clinical features, especially ocular involvement, in RA patients. The study included 297 persons (147 patients with RA and 150 healthy controls). Genomic DNA was isolated and genotyped using PCR assay for the MTHFR gene C677T and IL-4 gene 70bp VNTR polymorphisms. Our results show that there was statistically significant difference between the groups with respect to IL-4 genotype (p=0.01) and allele frequencies (p<0.002). There was no statistical significant difference in the genotype frequencies MTHFR gene, but allele frequencies showed statistically significant association (p=0.01). When we examined MTHFR and IL-4 genotype frequencies according to the clinical characteristics, we found that there was a difference between MTHFR genotypes and ocular involvement but it is not to a statistical significant degree (p=0.09). In the combined genotype analysis, MTHFR/IL-4 CCP2P2 combine genotype was estimated to have protective effect against RA, CTP1P2 combine genotype was found to be risk for RA. Our findings suggest that there is an association of IL-4 gene 70bp VNTR polymorphism and MTHFR C677T polymorphism with susceptibility of a person for development of RA.

Abstract
OBJECTIVE The primary purpose of this study was to establish the frequency of abnormal eating attitudes and behaviours, as measured by the Eating Attitude Test (EAT 40) in a sample of Turkish university students and to examine the relationship of such abnormalities to socio economic status, social and individual variables. METHOD The EAT 40, two other questionnaires and a personal data sheet were administered to a sample of 253 female undergraduates at Bogazici and Marmara Universities in Istanbul, Turkey. RESULTS Using the EAT 40 cut-off score of 30 established by (16) 7.9% of subjects were classified as having abnormal eating attitudes and behaviours. This subgroup of subjects was then compared with the remainder on all the other measures. No group differences were found for any of the SES variables. However, both social and individual variables were found to distinguish between groups in the predicted directions. DISCUSSION Abnormal eating attitudes and behaviours are now as common in Turkish students as they are in many other comparable western and, increasingly, non-western societies. In the current student sample these attitudes and behaviours were found to be related to social factors such as the perceived traditionality of parents as well as to individual risk factors such as negative perfectionism.

Abstract
OBJECTIVE The primary purpose of this study was to compare the factor structure of the Eating Attitudes Test (EAT) in a sample of Turkish university students with both that of the original Canadian study and that of a Turkish study conducted ten years earlier. METHOD The EAT 40 was administered to a sample of 270 female undergraduates at the Bogazici and Marmara universities in Istanbul, Turkey. RESULTS The factor structure produced more closely resembled the original than did that of the study conducted ten years ago. Of particular note was the presence of a bulimia factor which had not emerged in the previous Turkish study, together with a new factor labelled "Ambivalence about Eating". DISCUSSION Comparison of the two Turkish studies highlights the emergence of a bulimia factor not present ten years ago. This reflects clinical experience. Moreover the new Ambivalence about Eating factor is discussed in terms of the transitional nature of Turkish society and the role of a culture clash between traditional and westernized attitudes towards food. It is therefore predicted that the prevalence of eating disorders in Turkish culture will dramatically increase in the foreseeable future.
