Background: We sought to explore the interplay of multiple serum biomarkers of fibrosis and extracellular matrix remodeling with the results of liver histology in patients with nonalcoholic fatty liver disease (NAFLD)., Patients and Methods: Venous blood samples were collected from 80 patients with biopsy-proven NAFLD and 59 age-matched and sex-matched healthy controls. Serum levels of transforming growth factor (TGF)-β1, TGF-β2, matrix metalloproteinases (MMP)-1, MMP-2, MMP-7, MMP-9, MMP-10, tissue inhibitors of metalloproteinase (TIMP)-1, and TIMP-2 were determined by using the Luminex MagPix technology on a MAGPIX analyzer., Results: We documented significant differences in the levels of TGF-β1, TGF-β2, MMP-2, MMP-7, MMP-9, TIMP-1, and TIMP-2 between NAFLD patients and controls. However, none of these biomarkers was able to distinguish between nonalcoholic steatohepatitis and nonalcoholic fatty liver. TIMP-1 levels were significantly higher in patients with significant fibrosis (fibrosis stage ≥2; 2624±1261 pg/ml) than in those without (fibrosis stage 0-1; 2096±906 pg/ml; P=0.03). Moreover, serum levels of TIMP-1 were identified as the only independent predictor of histological fibrosis (β=0.298, t=2.7, P=0.007)., Conclusion: Our study provides insights into the association of multiple serum biomarkers of fibrosis and extracellular matrix remodeling with NAFLD histology. Notably, serum levels of TIMP-1 were identified as a clinically useful marker for distinguishing NAFLD patients with and without significant fibrosis.

Anaplastic thyroid carcinoma is a highly lethal malignancy. Previously, only five cases of a noninvasive form of anaplastic thyroid carcinoma with excellent prognosis were reported. We report a case of a 68-year-old man who presented with a 3.8 cm thyroid nodule diagnosed by fine needle aspiration biopsy as poorly differentiated spindled and epithelial malignant cells. Lobectomy and isthmusectomy were performed, and the final diagnosis was microinvasive anaplastic thyroid carcinoma arising in a poorly differentiated carcinoma. The patient remains disease-free after six years, even after hemithyroidectomy and radiation treatment. Noninvasive/microinvasive anaplastic thyroid carcinoma appears to be a different disease entity from classical anaplastic thyroid carcinoma, with favorable prognosis and long disease-free survival.

The 2015 Dietary Guidelines for Americans recommend limiting the intake of saturated fatty acids (SFAs) to <10% of energy/d and replacing dietary SFAs with unsaturated fatty acids. A Presidential Advisory from the American Heart Association recently released its evaluation of the relation between dietary fats and cardiovascular disease (CVD), and also recommended a shift from SFAs to unsaturated fatty acids, especially polyunsaturated fatty acids (PUFAs), in conjunction with a healthy dietary pattern. However, the suggestion to increase the intake of PUFAs in general, and omega-6 (n-6) PUFAs in particular, continues to be controversial. This review was undertaken to provide an overview of the evidence and controversies regarding the effects of ω-6 PUFAs on cardiometabolic health, with emphasis on risks and risk factors for CVD (coronary heart disease and stroke) and type 2 diabetes mellitus (T2D). Results from observational studies show that higher intake of ω-6 PUFAs, when compared with SFAs or carbohydrate, is associated with lower risks for CVD events (10-30%), CVD and total mortality (10-40%), and T2D (20-50%). Findings from intervention studies on cardiometabolic risk factors suggest that ω-6 PUFAs reduce concentrations of LDL cholesterol and non-HDL cholesterol in a dose-dependent manner compared with dietary carbohydrate, and have a neutral effect on blood pressure. Despite the concern that ω-6 fatty acids increase inflammation, current evidence from studies in humans does not support this view. In conclusion, these findings support current recommendations to emphasize consumption of ω-6 PUFAs as a replacement of SFAs; additional randomized controlled trials with cardiometabolic disease outcomes will help to more clearly define the benefits and risks of this policy.

Background: Few trials have examined the effects of coconut oil consumption in comparison with polyunsaturated fatty acid-rich oils such as corn oil., Objective: This trial assessed the effects of consuming foods made with corn oil compared with coconut oil on lipids, glucose homeostasis, and inflammation., Methods: This was a preliminary randomized crossover study of men (n = 12) and women (n = 13) with a mean age of 45.2 y, mean body mass index (in kg/m2) of 27.7, fasting LDL cholesterol ≥115 mg/dL and <190 mg/dL, and triglycerides (TGs) ≤375 mg/dL. Subjects consumed muffins and rolls providing 4 tablespoons (∼54 g) per day of corn oil or coconut oil as part of their habitual diets for 4 wk, with a 3-wk washout between conditions. Fasting plasma lipids and high-sensitivity C-reactive protein (hs-CRP) and glucose metabolism were assessed via an intravenous glucose tolerance test at baseline and 15 and 29 d of treatment. Responses were compared between treatments by ANCOVA., Results: Median baseline concentrations of LDL cholesterol, non-HDL cholesterol, total cholesterol (total-C), HDL cholesterol, total-C:HDL cholesterol, and TGs were 123, 144, 188, 46.0, 4.21, and 92.5 mg/dL, respectively. Changes from baseline for corn oil and coconut oil conditions, respectively, were: LDL cholesterol (primary outcome; -2.7% compared with +4.6%), non-HDL cholesterol (-3.0% compared with +5.8%), total-C (-0.5% compared with +7.1%), HDL cholesterol (+5.4% compared with +6.5%), total-C:HDL cholesterol (-4.3% compared with -3.3%), and TGs (-2.1% compared with +6.0%). Non-HDL cholesterol responses were significantly different between corn and coconut oil conditions (P = 0.034); differences between conditions in total-C and LDL cholesterol approached significance (both P = 0.06). Responses for hs-CRP and carbohydrate homeostasis parameters did not differ significantly between diet conditions., Conclusions: When incorporated into the habitual diet, consumption of foods providing ∼54 g of corn oil/d produced a more favorable plasma lipid profile than did coconut oil in adults with elevated cholesterol. This trial was registered at clinicaltrials.gov as NCT03202654.

Introduction: To compare the quality of life, areas of social, emotional, behavioural and mental problems and family functionality of gifted children and children of normal intelligence., Methods: The study included 49 gifted children aged 9-18 years and 56 age and gender-matched healthy children of normal intelligence. The Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL), and the Children's Depression Rating Scale were applied to all the cases. The Quality of Life Scale for Children, the Depression Scale for Children, the Trait-State Anxiety Inventory, and the Strengths and Difficulties Questionnaire- Adolescent Form were completed by all the participants. All the parents completed the Family Evaluation Scale, the Strengths and Difficulties Questionnaire- Parents Form and the Parents Form of the Quality of Life Scale for Children., Results: Compared to children of normal intelligence, gifted children described themselves as more inattentive and lively, social functionality was reported to be low and they had a worse perception of their physical health status. Gifted boys were determined to have more depressive symptoms than gifted girls. The parents of boys of normal intelligence reported lower academic performance than the parents of giftedboys. This difference was not determined for girls between the cases and comparative groups., Conclusion: All the findings obtained in this study suggest that gifted children are at risk in respect of mental health. Therefore, to be able to become healthy adults in a biopsychosocial aspect, it is important for the future of gifted children that this status can be identified at an early age, that they can receive appropriate education, that support and counselling are provided for emotional needs and that parents and teachers are fully informed., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors.

Objective: To compare the effects of high-intensity laser therapy (HILT) and a combination of transcutaneous nerve stimulation (TENS) with ultrasound (US) therapy on pain and functionality in patients with chronic lumbar radiculopathy., Methods: This prospective randomized comparative study was conducted in Department of physical medicine and rehabilitation, Turgut Ozal Medicine Center, Malatya, Turkey from April 2016 to September 2016. A total of 54 patients with chronic lumbar radiculopathy were enrolled in this study. The patients were randomly divided into two groups: Group 1 (n:27) received 10 sessions of a combination of hot pack, TENS, US and exercise, and Group 2 (n:27) received hot pack, HILT and exercise. The outcomes measured were low back with unilateral leg pain level measured by visual analog scale (VAS) and functionality measured with the Oswestry Disability Index (ODI) at the end of the therapy and four weeks later. p-value less than 0.05 considered statistically significant., Results: In two groups, VAS (low back with unilateral leg pain) and ODI scores showed significant changes. At the end of the 2 weeks intervention, participants in Group-1 showed a significantly greater decrease in pain than participants in Group-2. Statistically significant differences in pain variation and functionality (VAS and ODI) were observed four weeks after treatment sessions for participants in the TENS+US therapy group compared with participants in the HILT group., Conclusion: HILT and TENS+US combined with exercise were effective treatment modalities in decreasing the VAS and ODI scores. TENS+US combined with exercises were more effective than HILT combined with exercise., Competing Interests: Conflict of Interests: None

Purpose: The aim of this study was to determine plasma thiol-disulphide homoeostasis in patients with age-related cataract (ARC) and compare the results of the patients with healthy subjects. Plasma malondialdehyde (MDA) levels and catalase (CAT) activity were also investigated., Methods: The study included 53 cataract patients and 52 healthy volunteers. Native thiol-disulphide exchanges were determined using a novel and automated method. CAT activity was determined using the method described by Aebi, and MDA levels were calculated using the thiobarbituric acid method., Result: Native thiol and total thiol levels were significantly lower in the cataract patients compared with the controls (p < 0.001, p = 0.002, respectively). The disulphide levels of the cataract patients were significantly higher than the controls (p = 0.002). The ratios of disulphide/native thiol and disulphide/total thiol were statistically higher in the cataract patients compared with the control group (p < 0.001, p < 0.001, respectively). Furthermore, CAT activity was significantly lower in the cataract patient group compared with the control group (p < 0.001), and MDA levels were insignificantly higher in the patient group (p = 0.581)., Conclusions: Our study showed that dynamic thiol-disulphide homoeostasis has shifted towards disulphide formation, as a result of thiol oxidation in ARC patients. The present study is the first to measure thiol-disulphide homoeostasis in ARC patients with a novel automated assay. This study supports the hypothesis that cataract is an oxidative disorder. Further studies are required in order to examine the relationship between oxidative stress and the development of cataract formation.

Background and Purpose: Epilepsy with photosensitivity (PSE) is one of the reflex epilepsy types with pathophysiology still unexplained. In our study we aimed to evaluate the clinical, electroencephalogram (EEG) and prognosis of patients with PSE diagnosis., Methods: A total of 44 patients with PSE diagnosis according to international classification were included in this retrospective and cross-sectional study. The age, gender, syndrome, clinical and EEG characteristics of patients, and treatment response were investigated., Results: The mean age was 22.09±6.49 years for 28 females and 16 males included in the study. Of patients, 17 had idiopathic photosensitive occipital lobe epilepsy (IPOLE), 11 had juvenile myoclonic epilepsy (JME), 11 had other PSE and 5 had juvenile absence epilepsy (JAE), with the most common visual trigger factors television and sunlight. In terms of seizure type, the most common was generalized tonic clonic seizure (GTCS), with myoclonus, absence and other seizure types observed. There was family history present in 17 patients and valproic acid was most commonly used for treatment., Conclusion: As noted in the literature, our data show that PSE has defined age group and clinical presentation, good prognosis but requires correct choice of medication for treatment. It is thought that good description of these epilepsy types will reduce misdiagnosis and mistreatment rates.

This paper presents a proof-of-concept optical detector array sensor system to be used in Unmanned Underwater Vehicle (UUV) navigation. The performance of the developed optical detector array was evaluated for its capability to estimate the position, orientation and forward velocity of UUVs with respect to a light source fixed in underwater. The evaluations were conducted through Monte Carlo simulations and empirical tests under a variety of motion configurations. Monte Carlo simulations also evaluated the system total propagated uncertainty (TPU) by taking into account variations in the water column turbidity, temperature and hardware noise that may degrade the system performance. Empirical tests were conducted to estimate UUV position and velocity during its navigation to a light beacon. Monte Carlo simulation and empirical results support the use of the detector array system for optics based position feedback for UUV positioning applications., Competing Interests: The authors declare no conflict of interest.

Background/aim: The pedicled transverse rectus abdominis myocutaneous (TRAM) flap remains widely used as a breast reconstruction technique. The bipedicled TRAM flap is not as preferable as it was formerly, mainly because of its donor site complications. However, in a number of situations, a bipedicled TRAM flap may be the only alternative. Therefore, a three-layer primary closure technique used with bipedicled TRAM flap breast reconstructions that can avoid donor site complications without using a mesh is presented., Materials and Methods: A retrospective study was performed that included patients who underwent bipedicled TRAM flap breast reconstruction with the three-layer primary closure technique. Between 2000 and 2015, 124 breast reconstruction patients were reviewed for donor site morbidity., Results: During the 15-year study period, 106 patients had conventional bipedicled TRAM flaps and 18 had bipedicled TRAM flaps with a surgical delay procedure. For all groups, none of the patients developed abdominal wall hernia, but three patients had bulging. Partial flap loss was the most common flap complication, present in 6 flaps (4.8%)., Conclusion: The suturing technique studied provided abdominal wall closure without the use of a mesh even when utilizing a bilateral pedicle with very low complication rates.

Aim of the Study: To investigate the effects of dosevolume parameters of brain parenchyma, optic nerves (ONs) and cribriform plate (CP), which were determined on central nervous system (CNS) control in pediatric leukemia patients who have undergone prophylactic cranial irradiation (PCI) at our department., Patients and Methods: In the current study, the records of 14 patients were examined retrospectively. Along with the minimum and maximum doses for brain and CP, D95% (minimal dose received by the 95% volume of a structure) and V95% (percent volume of target receiving 95% of prescribed dose) could be obtained from the dose-volume histogram. Statistical analyses were conducted using the Mann Whitney test in SPSS-15., Results: ALL/AML ratio was 9/5. CNS relapse was observed only in 2 patients. The minimum dose was 1249 (1100-1782) cGy, 1036 (547-1651) cGy, 856 (308-1460) cGy and 1234 (922-1727) cGy for brain parenchyma, right ON, left ON and CP, respectively. The value of D95%/D was 1.01 (1-1.06) and 0.99 (0.92- 1.06) for brain parenchyma and CP, respectively. V95% was 99.8 % (98.6%-100%) and 98.1% (80.5%-100%) for brain parenchyma and CP, respectively. The analyses revealed that none of the target tissue dose-volume parameters for PCI affected CNS relapse (p>0.05)., Conclusion: In our study; it was found that the dosevolume parameters of the brain, CP and ONs did not have any effect on CNS relapse. Along with the other clinical factors, the scarce number of patients included in the study might have concealed the effects of parameters related to RT.

Introduction: Growing evidence suggests that multiple factors, such as insulin resistance, nutritional factors, gut microbiota, and hormones released from the adipose tissue, act together on genetically predisposed individuals. We aimed to investigate whether various single-nucleotide polymorphisms (SNPs) play a role in the development of nonalcoholic fatty liver disease (NAFLD) and severity of liver damage in the Anatolian population., Methods: Two hundred and sixteen patients with biopsy-proven NAFLD and 150 control participants, aged 18-70 years, were consecutively enrolled in this multicenter study. Blood samples were genotyped for the PNPLA3 (rs738409), IL28B (rs12979860, rs12980275, rs8099917), PPAR-α 227 ALA, PPAR-γ pro 12 ALA, SOD2 C47T, and LOX-1 IVS4-14 polymorphisms using the custom-made LightSNiP assays on a LightCycler 480 II instrument., Results: Genotypic distributions of PNPLA3 rs738409 SNPs were different between NAFLD and control participants, but not for other SNPs. The PNPLA3 rs738409 GG polymorphism was associated with a 27-fold increased risk of development of NAFLD (odds ratio=27.8, 95% confidence interval: 3.5-218.4; P=0.002). Patients with the PNPLA3 GG genotype had higher nonalcoholic fatty liver disease activity score levels compared with patients with the PNPLA3 CC genotype (P<0.005). NAFLD patients without fibrosis had a higher frequency of IL28B rs12979860 TT and rs12980275 GG genotypes compared with NAFLD patients with fibrosis (P<0.005)., Conclusion: The present study proposes that polymorphisms in the PNPLA3 gene have highly predictive value in the development of NAFLD and are independently associated with the severity of liver histology in patients with NAFLD. The results of this study suggest that IL28B rs12979860 TT or rs12980275 GG may play an important protective role against the development of advanced fibrosis and even cirrhosis.

Despite having the second highest mortality associated with cancer, currently Sorafenib is the only FDA-approved chemotherapeutic agent available for liver cancer patients which can only improve survival for few months. In this study, various pyrazolic chalcone analogous compounds were synthesized and evaluated as potential chemotherapeutic agents for the treatment of hepatocellular carcinoma (HCC). Modifying the central pyrazole ring at the C(3)-position with different heteroaryl rings and substituting the C(4)-position of pyrazole with differently substituted chalcone moiety produced fouthy two variant compounds. For all these compounds, cytotoxicity was evaluated using sulforhodamine B assay and real time cell growth tracking, respectively. Based on 50% inhibitory concentration (IC 50 ) values, compounds 39, 42, 49, and 52 were shown to exhibit potent cytotoxic activity against all the cancer cell lines tested, and had better cytotoxic activities than the well-known chemotherapeutic drug 5-FU. Therefore, these compounds were chosen to be further evaluated in a panel of HCC cell lines. Flow cytometric analysis of HCC cells treated with compounds 39, 42, 49, and 52 demonstrated that these compounds caused cell cycle arrest at G2/M phase followed by the apoptotic cell death and impaired cell growth as shown by real-time cell growth surveillance. Consistent with these results, western blotting of HCC cells treated with the compounds resulted in molecular changes for cell cycle proteins, where p21 levels were increased independent of p53 and the levels of the key initiators of mitosis Cyclin B1 and CDK1 were shown to decrease upon treatment. In conclusion, chalcone derivatives 42 and 52 show potent bioactivities by modulating the expression of cell-cycle related proteins and resulting in cell-cycle arrest in the HCC cell lines tested here, indicating that the compounds can be considered as preclinical candidates., (Copyright © 2017 Elsevier Masson SAS.

Introduction: The aim of the present study was to evaluate the neuropsychological outcomes of patients with medically intractable unilateral mesial temporal lobe epilepsy (MTLE) due to hippocampal sclerosis (HS) treated either by anterior temporal lobectomy (ATL) or selective amygdalohippocampectomy (SAH)., Methods: This was a retrospective study where 67 patients who had undergone surgery for MTLE were evaluated. Thirty-two patients underwent ATL and 35 underwent SAH. All patients underwent a detailed neuropsychological evaluation before and 1 year after surgery., Results: The verbal memory outcome was unchanged after left-sided surgery, whereas learning capacity increased after right-sided surgery (p=0.038). The visual memory outcome improved after right-sided surgery. Improvement of executive functions, particularly in the resistance of interference pattern in the Stroop Test, shortened 5th card time (p=0.000), and decreased corrections (p=0.003), after right-sided surgery and increased attention (p=0.027) after left-sided surgery were observed. After both surgery types, although statistically insignificant, there was a marked decrease in incorrect answers in the Stroop Test, which also showed an improvement in the resistance of interference pattern. Moreover, there was a significant decrease in switching errors with word pairs in the Verbal Fluency Test (p=0.008) after right-sided surgery. When the two sides were compared, we observed that the recall phase of the verbal memory worsened (p=0.018); however, the recognition phase improved (p=0.015) after left-sided surgery. Additionally, the short-term visual memory was better for both sides (p=0.035)., Conclusion: Our results showed that patients with left MTLE were not worsened in verbal memory, but despite improved recognition, they have some problems in recalling information and only a minor improvement in attention. Patients with right MTLE improved in their verbal learning capacity, visual memory, and resistance of interference pattern 1 year after surgery. It was thus shown that while epilepsy surgery is associated with some negative cognitive changes, it may also improve some cognitive functions., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors.

Background: Radiographic severity of ankylosing spondylitis (AS) shows such great variance that some patients never develop syndesmophytes throughout the entire disease span, whereas some develop bamboo spine relatively early., Objective: To study the association between ERAP1 , IL23R and PTGER4 single nucleotide polymorphisms (SNPs) and radiographic severity in AS patients., Methods: rs27044 and rs30187 ( ERAP1 ), rs11209032 ( IL23R ) and rs10440635 ( PTGER4 ) SNPs were genotyped in 235 AS patients fulfilling the modified New York criteria. Patients were classified as mild- and severe-AS according to modified Stoke AS spinal score (mSASSS). Mild-AS is defined as having mSASSS of "0" following at least 10 years of disease duration. Severe-AS is defined as having mSASSS of >20 (patients with mild vertebral changes ( i.e. squaring or erosions) were omitted for clear stratification) regardless of disease duration., Results: The genotype distributions and allele frequencies of ERAP1 rs27044 and rs30187, IL23R rs11209032 and PTGER4 rs10440635 SNPs were similar in mild- (n=171, mSASSS=0, 55.6% HLA-B27 positive) and severe-AS patients (n=64, mSASSS=48.5±17.8, 73.4% HLA-B27 positive). After adjustment for clinical differences between groups (gender, disease duration, HLA-B27 and smoking status) by logistic regression analysis, none of the alleles in the investigated SNPs were found to be associated with radiographic severity of AS., Conclusion: In radiographically well-categorized AS patients, ERAP1 rs27044 and rs30187, IL23R rs11209032 and PTGER4 rs10440635 SNPs are not found to be associated with radiographic severity of AS.

Objective: There is no other screening program close to the success rate of PAP test. Cervical cytology constitutes a large workload so that quality control in cervical cytology is important for the quality assurance of pathology laboratories., Material and Method: In this study, we collected the cervical cytology results from all over Turkey and discussed the parameters influencing the quality of the PAP test. The study was conducted with Turkish gynaecopathology working group and 38 centers (totally 45 hospitals) agreed to contribute from 24 different cities. The study was designed to cover the cervical cytology results during 2013. The results were evaluated from the data based on an online questionnaire., Results: The total number of Epithelial Cell Abnormality was 18,020 and the global Epithelial Cell Abnormality rate was 5.08% in the total 354,725 smears and ranging between 0.3% to 16.64% among centers. The Atypical squamous cells /Squamous intraepithelial lesion ratios changed within the range of 0.21-13.94 with an average of 2.61. When the centers were asked whether they performed quality assurance studies, only 14 out of 28 centers, which shared the information, had such a control study and some quality parameters were better in these centers., Conclusion: There is an increase in the global Epithelial Cell Abnormality rate and there are great differences among centers. Quality control studies including the Atypical squamous cells/Squamous intraepithelial lesion ratio are important. Corrective and preventive action according to quality control parameters is a must. A cervical cytology subspecialist in every center can be utopic but a dedicated pathologist in the center is certainly needed.

Objective: Inter-observer differences in the diagnosis of HPV related cervical lesions are problematic and response of gynecologists to these diagnostic entities is non-standardized. This study evaluated the diagnostic reproducibility of "cervical intraepithelial neoplasia" (CIN) and "squamous intraepithelial lesion" (SIL) diagnoses., Material and Method: 19 pathologists evaluated 66 cases once using H&E slides and once with immunohistochemical studies (p16, Ki-67 and Pro-ExC). Management response to diagnoses was evaluated amongst 12 gynecologists. Pathologists and gynecologists were also given a questionnaire about how additional information like smear results and age modify diagnosis and management., Results: We show moderate interobserver diagnostic reproducibility amongst pathologists. The overall kappa value was 0.50 and 0.59 using the CIN and SIL classifications respectively. Impact of immunohistochemical evaluation on interpretation of cases differed and there was lack of statistically significant improvement of interobserver diagnostic reproducibility with the addition of immunohistochemistry. We saw that choice of treatment methods amongst gynecologists varied and overall concordance was only fair to moderate. The CIN2 diagnostic category was seen to have the lowest percentage agreement amongst both pathologists and gynecologists. We showed that pathologists had diagnostic "styles" and gynecologists had management "styles"., Conclusion: In summary each pathologist had different diagnostic tendencies which were affected not only by histopathology and marker studies, but also by the patient management tendencies of the gynecologist that the pathologist worked with. The two-tiered modified Bethesda system improved diagnostic agreement. We concluded that immunohistochemistry should be used only to resolve problems in select cases and not for every case.

Peripheral nerve gaps exceeding 1 cm require a bridging repair strategy. Clinical feasibility of autogenous nerve grafting is limited by donor site comorbidity. In this study we investigated neuroregenerative efficacy of autogenous vein grafts implanted with tissue fragments from distal nerve in combination with vascular endothelial growth factor (VEGF) or mesenchymal stem cells (MSCs) in repair of rat peripheral nerve defects. Six-groups of Sprague-Dawley rats (n = 8 each) were evaluated in the autogenous setting using a 1.6 cm long peroneal nerve defect: Empty vein graft (group 1), Nerve graft (group 2), Vein graft and nerve fragments (group 3), Vein graft and nerve fragments and blank microspheres (group 4), Vein graft and nerve fragments and VEGF microspheres (group 5), Vein graft and nerve fragments and MSCs (group 6). Nerve fragments were derived from distal segment. Walking track analysis, electrophysiology and nerve histomorphometry were performed for assessment. Peroneal function indices (PFI), electrophysiology (amplitude) and axon count results for group 2 were -9.12 ± 3.07, 12.81 ± 2.46 mV, and 1697.88 ± 166.18, whereas the results for group 5 were -9.35 ± 2.55, 12.68 ± 1.78, and 1566 ± 131.44, respectively. The assessment results did not reveal statistical difference between groups 2 and 5 (P > 0.05). The best outcomes were seen in group 2 and 5 followed by group 6. Compared to other groups, poorest outcomes were seen in group 1 (P ≤ 0.05). PFI, electrophysiology (amplitude) and axon count results for group 1 were -208.82 ± 110.69, 0.86 ± 0.52, and 444.50 ± 274.03, respectively. Vein conduits implanted with distal nerve-derived nerve fragments improved axonal regeneration. VEGF was superior to MSCs in facilitating nerve regeneration. © 2015 Wiley Periodicals, Inc.

The aim of this study was to investigate thiol/disulfide homeostasis in asphalt workers who are exposed to polycyclic aromatic hydrocarbons occupationally. The study was carried out in 34 nonsmoker asphalt workers. Additionally, 35 healthy nonsmoker volunteers were recruited as control group. Thiol and disulfide concentrations were determined using the novel automated measurement method. Levels of urinary 1-OH-pyrene were analyzed by liquid chromatography. Disulfide/thiol ratio was significantly higher in exposed group (p = .034). Also, a positive correlation was detected between disulfide/thiol ratio and 1-OH-pyrene values (r = .249, p = .036). Thiol/disulfide homeostasis was found to be disturbed in asphalt workers. The novel test used in this study may be useful for evaluating the oxidative status in polycyclic aromatic hydrocarbon (PAH) exposure.

Objective: To determine the role of a disintegrin and metalloproteinase with thrombospondin type 1 motif (ADAMTS1) and fragmented versican in the myocardial infarction (MI) process in humans and to evaluate the diagnostic efficacy of ADAMTS1 for postmortem diagnosis of MI., Methods: Thirty autopsied individuals were allocated into 2 groups, namely, a study group of individuals who died of myocardial infarction (n = 20), and a control group who died of trauma (n = 10). We performed standard immunohistochemical staining on myocardial tissue specimens, studying anti-ADAMTS1, anti-versican, and anti-versican C terminal peptide sequence (DPEAAE) fragments., Results: Strong, diffuse staining was observed throughout myocardial tissue for ADAMTS1 in the 2 groups. However, in the study group, we observed no expression for ADAMTS1 around fibrotic areas but detected slight staining in coagulative and necrotic zones., Conclusion: Similar localizations of ADAMTS and fragmented versican in human heart tissue indicate that versican presumably is cleaved by ADAMTS1. Hence, ADAMTS1 can be regarded as a new marker for postmortem differential diagnosis of MI., (© American Society for Clinical Pathology, 2016. All rights reserved.

Objective: To assess thiol/disulphide homeostasis and lipid accumulation product index, and to determine whether they are associated with increased cardiovascular disease (CVD) risk or not in overweight adolescents with polycystic ovary syndrome (PCOS)., Design: Case-control study., Setting: Education and Research Hospital., Patients: Group 1: 43 overweight+PCOS, Group 2: 45 normal weight+PCOS, Group 3: 27 overweight adolescents and Group 4: 96 age-matched, normal weight healthy controls., Interventions: Serum lipid profiles, hormonal parameters and thiol/disulphide homeostasis were measured. Lipid accumulation index (LAP index) and homeostasis model assessment (HOMA-IR) were calculated., Main Outcome Measures: The relation between thiol/disulphide homeostasis and LAP index, and increased CVD risk were evaluated in overweight adolescents with PCOS., Results: Native and total thiol levels were significantly lower in overweight+PCOS adolescents when compared with both normal weight PCOS and control adolescents (P = 0·002). LAP index values were significantly higher in Group 1 when compared separately with the rest of the three groups (P < 0·001). Multivariable logistic regression analysis revealed serum total thiol levels of lower than 405·45 μmol/l were independently associated with increased risk of CVD in overweight PCOS adolescents (OR: 1·019, 95% CI: 1·001-1·036). In addition, a LAP index greater than 21·54 was also associated with increased CVD risk in overweight PCOS adolescents (OR: 1·270, 95% CI: 1·174-1·374)., Conclusion: In conclusion, we suggest that increased LAP index and decreased total thiol levels may contribute to the increased CVD risk in overweight adolescents with PCOS., (© 2015 John Wiley & Sons Ltd.)

Presented case was a 36-year-old deceased man with a sequel of poliomyelitis who was reportedly found death at home. On external examination at autopsy, deformity of the lower extremity secondary to polimyelitis, and an obliquely coursing scar tissue 5 cm in length at the same level with the costal arch on the right axillary line were seen. On internal examination at autopsy, diaphragmatic eventration caused by bilateral elevation of the diaphragm towards thoracic cavity was detected. On the left side, stomach, spleen, and small intestines, and on the right side liver were pushed into the thoracic cavity. Cause of death was reported as heart failure of the patient with bilateral diaphragmatic eventration. We aimed to discuss rarely encountered diaphragmatic eventration in autopsy practice from a perspective of forensic medicine.

Reported case was 63 years old forester died suddenly in the village. Autopsy examination revealed massive coagulated haemorrhage filling the right hemithorax, neither free fluid nor blood were observed in the abdominal cavity. Abdominal aortic aneurysm 20x15x15 cm in size was examined. We aimed to report the rare case of abdominal aortic aneurysm presented with transdiafragmatic rupture and bleeding in the right hemithorax.

Because of the way of life Greek philosopher Diogenes lived, in the medical literature some older individuals characterized with collection of symptoms and the psychopathology associated with the lack of concern about a person's living conditions were called as Diogenes Syndrome. In this study we presented a case in terms of Diogenes Syndrome. We aimed to discuss by using the recent medical literature. Our case was a 62 year old male living alone and there were a variety of diseases he had. Diogenes Syndrome was previously identified in 30 elderly patients for the first time in 1975. As well as the typical clinical features of Diogenes Syndrome were defined, for being of potential forensic value, case characteristics belonging to the crime scene, and also probable changes that may be encountered at autopsy were discussed.

Caustic chemicals cause destruction in tissues even long after the initial exposure. This study reported a case of recurrent graft lysis encountered throughout the treatment of a sodium hydroxide burn. A caustic burn on the ankle of a patient was reconstructed with split thickness skin grafts thrice in a period of four months. The burn site healed uneventfully after each skin grafting. However, weeks after each successful graft take, even though the patient did not experience any trauma at his operated ankle, an eczematous blistering at the skin graft site was observed. Thereafter, skin grafts almost totally sloughed over time even after each successful graft take. Six months after the initial burn and recurrent skin graft lysis, the defect site was reconstructed with medial plantar flap. At the postoperative ninth month follow-up, there was no sign of the blistering or skin loss at the burn area after definitive flap surgery. Recurrent graft lysis, in a few weeks after total skin graft take is an unusual complication for most of the burn cases. Caustic burns may have a deceptively superficial appearance concealing the chemical reactions that further damage the tissue. Therefore, early surgical interventions such as deep debridement and graft surgery should be kept in mind as primary treatment options.

69-year-old male was found dead at the roadside in October month, death was declared suspicious by local prosecutor and autopsy was mandated. At autopsy, a large number of dark brown colored, ovalshaped lesions ranging from 1-15 mm under the mucosa defined as Wischnewsky spots, when stomach was dissected were observed. For the formation mechanism of Wischnewsky spots, there has no definite conclusions; more studies are needed on a case series.

Background/aims: Inflammatory bowel disease, a chronic inflammatory disease with unknown etiology, affects the small and large bowel at different levels. It is increasingly considered that innate immune system may have a central position in the pathogenesis of the disease. As a part of the innate immune system, bactericidal permeability increasing protein has an important role in the recognition and neutralization of gram-negative bacteria. The aim of our study was to investigate the involvement of bactericidal permeability increasing protein gene polymorphism (bactericidal permeability increasing protein Lys216Glu) in inflammatory bowel disease in a large group of Turkish patients., Patients and Methods: The present study included 528 inflammatory bowel disease patients, 224 with Crohn's disease and 304 with ulcerative colitis, and 339 healthy controls., Results: Bactericidal permeability increasing protein Lys216Glu polymorphism was found to be associated with both Crohn's disease and ulcerative colitis (P = 0.0001). The frequency of the Glu/Glu genotype was significantly lower in patients using steroids and in those with steroid dependence (P = 0.012, OR, 0.80; 95% confidence interval [CI]: 0.68-0.94; P = 0.0286, OR, 0.75; 95% CI: 0.66-0.86, respectively). There was no other association between bactericidal permeability increasing protein gene polymorphism and phenotypes of inflammatory bowel disease., Conclusions: Bactericidal permeability increasing protein Lys216Glu polymorphism is associated with both Crohn's disease and ulcerative colitis. This is the first study reporting the association of bactericidal permeability increasing protein gene polymorphism with steroid use and dependence in Crohn's disease.

Aim: The aim of the study was to investigate the effectiveness of zofenopril in an experimental model of ovarian torsion in rats with histologic and biochemical assessments., Material and Methods: Experimental procedures were performed on 35 female rats (Wistar albino). Rats were randomly divided into five groups as: sham (sham operated, n = 7); vehicle group 1 (torsion-detorsion, n = 7) with 2 h ischemia and 2 h reperfusion; vehicle group 2 (torsion-detorsion, n = 7) with 2 h ischemia and 5 days' reperfusion; zofenopril group 1 (torsion-detorsion, n = 7) with 2 h ischemia, 2 h reperfusion and a signal dose of oral 15 mg/kg zofenopril; and zofenopril group 2 (torsion-detorsion, n = 7) with 2 h ischemia, 5 days' reperfusion and 5 days' oral 15 mg/kg zofenopril. A scoring of histopathologic evaluation was performed on the ovaries according to congestion, bleeding, edema, and cellular degeneration. Biochemical assessments included catalase, tissue malondialdehyde and protein carbonyl., Results: Compared with the vehicle groups, histopathologic scores, tissue malondialdehyde and protein carbonyl levels, which reflect oxidative stress markers, were significantly lower in the zofenopril groups. Furthermore, catalase levels were significantly increased in the zofenopril group., Conclusion: Our study results revealed that zofenopril attenuates injury induced by ischemia-reperfusion on rat ovary., (© 2014 The Authors.

The principal aim of skin expansion is to provide additional donor tissue without extra donor-site morbidity. Most of the reports about tissue expansion are focused on the properties of expander. Donor-site decision is usually underestimated. Here, we offer to use the defect area and surrounding healthy tissue as the donor site.In 4 cases, expanders were placed just under the defect in a fashion to extend 1 to 2 cm more laterally toward the encircling healthy tissue. The expanded tissue was not mobilized for longer distances; thus, there was no loss in flap gain. The resulting final scar was linear or crescentic. In the Alagoz technique, tissue gain similar in size to the defect is sufficient for reconstruction. The simpler the flap, the best the resulting scar.

Myocardial bridging is a congenital coronary pathology described as a segment of coronary artery which courses through the myocardial wall beneath the muscle bridge. Although the myocardial bridging prognosis is benign, have been also reported sudden death in medical literature. ¬A 30-year-old married woman was found dead at her home. After local prosecutors' investigation the death was declared as suspicious and forensic autopsy was obliged. The left anterior descending coronary artery was detected embedded deeply in the myocardium 2 cm from its coronary ostial origin. There were no other pathology to explain death. We analyzed sudden death case occurred because of myocardial bridging and the pathophysiological mechanisms in the light of medico-legal literature.

Background: Transient elastography (TE) has recently emerged as an accurate noninvasive imaging method for the diagnosis of liver fibrosis in nonalcoholic fatty liver disease (NAFLD). Here, we tested whether adding serum measures of serum procollagen-III peptide (PIIIP) and caspase-cleaved cytokeratin 18 fragment (M30) to TE could improve its diagnostic accuracy in patients with biopsy-proven NAFLD., Patients and Methods: TE was performed in 87 patients with NAFLD. Serum PIIIP and M30 levels were determined by enzyme-linked immunosorbent assay. Liver histology was considered the gold standard. The diagnostic accuracies were assessed by measuring the area under the receiver operating curve., Results: At histopathological examination, 34 patients (39.1%) had significant fibrosis (F2-F4) and 19 patients (21.8%) had advanced fibrosis (F3-F4). Both TE and serum M30 levels were independent predictors of fibrosis, whereas no association was found with PIIIP. No significant differences in terms of sensitivity and specificity for both significant and advanced fibrosis were evident for TE, serum M30, or their combination. Moreover, the area under the receiver operating curves of serum M30 combined with TE did not differ significantly from those of either test alone., Conclusion: Both TE and serum M30 levels are accurate for the noninvasive diagnosis of fibrosis in NAFLD. However, their combination did not improve the overall diagnostic accuracy.

Liposarcoma is very rare mesenchymal tumor that occurs in deep soft tissue and mostly seen in limbs and retroperitoneum, accounts for 24% of extremity and 45% of retroperitoneal soft tissue sarcomas. Retroperitoneal liposarcomas are typically present with advanced disease and often carry a poor prognosis. Retroperitoneal liposarcomas grow slowly in the very expandable retroperitoneal space in the deeply hidden and clinically silent therefore diagnosis is usually made late. Liposarcomas have five histological subtypes; well-differentiated liposarcoma (WDLS), dedifferentiated liposarcoma (DDLS), pleomorphic, myxoid and round cell liposarcoma. Our case is 81-year-old male who was found dead in the village homeless shelter. This was classified as a suspicious death and transferred to our service for autopsy. The external examination revealed rectal prolapse, abdominal distension and scrotal swelling. The internal autopsy showed green membrane on the peritoneum, brown smelly contents in the abdominal space, a perforation area 1.5x1 cm in size that in the first part of the duodenum and the dimension of tumor was 48x30x6 cm in the retroperitoneal space. The pathological report was dedifferentiated liposarcoma. We present a rare case of a dedifferentiated retroperitoneal liposarcoma with duodenal ulcer perforation.

Objective: The aim of the present study is to investigate the efficiency of colchicine in the experimental rat ovarian torsion model in the light of histological and biochemical data., Study Design: A total of 35 Wistar albino female rats were randomly divided into 5 groups, group 1: (control-sham operated, n = 7); group 2: (torsion/detorsion, n = 7) 2 hours of ischemia and 2 hours of reperfusion; group 3: (torsion/detorsion, n = 7), 2 hours of ischemia and 5 days of reperfusion; group 4: (torsion/detorsion, n = 7) 2 hours of ischemia and 2 hours of reperfusion and a signal dose of oral 1 mL/kg colchicine; and group 5: (torsion/detorsion, n = 7), 2 hours of ischemia and 5 days of reperfusion and 5 days of oral 1 mg/kg colchicine. Histopathologic evaluation was performed by a scoring that assesses congestion, bleeding, edema, and cellular degeneration in the ovarian tissue. Catalase, tissue malondialdehyde (MDA), and protein carbonyl levels were calculated., Results: The histopathologic scores, MDA, and protein carbonyl levels in the control and colchicine groups were significantly lower than groups 2 and 3 (P < .001). Catalase activities were significantly higher in the control and colchicine groups than in groups 2 and 3 (P < .001). The results of the histopathologic parameters and biochemical markers showed that protective effects of colchicine treatment persisted up to 5 days., Conclusion: Our study results revealed that colchicine reduced ovarian ischemia-reperfusion injury in experimental rat ovarian torsion model. As the ovarian detorsion is the first choice of the treatment modality in the early phase, antioxidant and anti-inflammatory treatment modalities like colchicine might be used to reduce ovarian ischemia-reperfusion injury., (© The Author(s) 2014.)

Elevated triglycerides (TG) or low high density lipoprotein cholesterol (HDL-C) levels are common cardiometabolic risk factors in children. From a systems genetics standpoint, Visualization of Statistical Epistasis Networks (ViSEN) is a nonparametric entropy-based method that can characterize the global structure of interacting genetic factors. We identified a novel set of connected genetic and cardiometabolic risk factors with strong and significant interaction effects on two important dyslipidemia phenotypes (low HDL-C and high TG) in children and adolescents. Study participants were recruited from five schools in Istanbul, Turkey (n=360; 170 boys, 190 girls). Participants with TG levels≥75th and HDL-C levels≤25th percentile were defined as 'high TG' and 'low HDL-C', respectively. We genotyped participants for six single nucleotide polymorphisms (SNPs) in five genes with known associations to lipid levels (rs328 in LPL, rs708272 in CETP, rs1800588 in LIPC, rs1800977 in ABCA1, rs1799941 and rs6257 in SHBG gene). ViSEN was used to identify associations with dyslipidemia phenotypes. There were 71 (50 males, 21 females) and 93 (60 males and 33 females) subjects with low HDL-C and high TG, respectively. Biological variables including age, gender, and BMI were significantly associated with both phenotypes (p<0.001). Importantly, a single SNP, rs708272, was associated with low HDL-C (IG=2.24%, p=0.026). Pairwise and higher order interaction analyses in the full dataset for low HDL-C and high TG revealed the largest effects in the models containing rs1800977, rs708272, age (IG=6.20%, p=0.046) and rs1800588, age, BMI (IG, 3.06%, p=0.022), respectively. In conclusion, the present study brings us a step closer to a systems genetic approach in understanding lipid phenotypes in children. Further efforts can integrate population and laboratory-based studies, hence accelerate the preventive medicine efforts.

The functional role of IGFBP5 in breast cancer is complicated. Experimental and bioinformatics studies have shown that IGFBP5 is targeted by miR-140-5p and miR-193b, although this has not yet been proven in clinical samples. The aim of this study was to evaluate the expression of miR-140-5p and miR-193b in breast cancer and adjacent normal tissue and assess its correlation with IGFBP5 and the clinicopathological characteristics of the tumors. IGFBP5 protein expression was analyzed immunohistochemically and IGFBP5, miR-140 and miR-193b mRNA expression levels were analyzed with real-time RT-PCR. Tumor tissue had higher miR-140-5p expression than adjacent normal tissue (p = 0.015). Samples with no immunohistochemical staining for IGFBP5 showed increased miR-140-5p expression (p = 0.009). miR-140-5p expression was elevated in invasive ductal carcinomas (p = 0.002), whereas basal-like tumors had decreased expression of miR-140-5p compared to other tumors (p = 0.008). Lymph node-positive samples showed an approximately 13-fold increase in miR-140-5p expression compared to lymph node-negative tissue (p = 0.049). These findings suggest that miR-140-5p, but not miR-193b, could be an important determinant of IGFBP5 expression and clinical phenotype in breast cancer patients. Further studies are needed to clarify the expressional regulation of IGFBP5 by miR-140-5p.

The aim of this paper was to report a rare cause of radionecrosis and its long-term results. Iridium-192 ((192)Ir) is commonly used for radiography as a gamma ray source to locate flaws in welds and metal components in gas and oil industry. A 38-year-old man was subjected to radiation unintentionally. One month after the exposure wounds were appeared on the second and third fingers, and they were treated by conventional wound care and hyperbaric oxygen therapy. However wounds were relapsed one year later that brought the patient to us. The wounds were treated by wound care and hyperbaric oxygen therapy. When the patient was brought to us one year later the result was interesting. The third finger's pulp (there was not any wound one year before) was contracted and one third of the distal phalanx was exposed., (Copyright © 2014 Elsevier Ltd and ISBI. All rights reserved.)

Background: Metabolic syndrome (MetS) is a complex disorder characterized by coexistence of several cardiometabolic (CM) factors, i.e. hyperlipidemia, obesity, high blood pressure and insulin resistance. The presence of MetS is strongly associated with increased risk of cardiovascular disease (CVD). The syndrome was originally defined as an adult disorder, but MetS has become increasingly recognized in children and adolescents., Methods: Genetic variants influence biological components common to the CM factors that comprise MetS. We investigated single locus associations between six single nucleotide polymorphisms (SNPs), previously shown to modulate lipid or sex hormone binding globulin (SHBG) levels, with MetS in a Turkish pediatric cohort (37 cases, 323 controls)., Results: Logistic regression analysis revealed a significant association between rs1799941, located in SHBG, and MetS (OR = 3.09, p-value = 0.006). The association with MetS remained after sequential adjustment for each CM factor included in the syndrome definition, indicating that the identified association is not being driven by any single trait. A relationship between rs1799941 and SHBG levels, was also discovered, but it was dependent on MetS status. In control subjects, the A allele of rs1799941 associated with a significant increase in SHBG levels (p = 0.012), while in cases there was no association between rs1799941 and SHBG levels (p = 0.963)., Conclusions: The significant association between rs1799941 and MetS in children is not contingent on any single CM trait. Additionally, the presence of MetS may abrogate effect of rs1799941 polymorphism on SHBG levels in children.

RNA interference (RNAi) holds considerable promise as a novel therapeutic strategy in the silencing of disease-causing genes. The development of effective delivery systems is important for the use of small interfering RNA (siRNA) as therapy. In the present study, we investigated the effect on breast cancer cell lines and the co-delivery of liposomes containing siHIF1-α and siVEGF. In order to achieve the co-delivery of siHIF1-α and siVEGF and to obtain lower cytotoxicity, higher transfection and silencing efficiency, in this study, we used chitosan-coated liposomal formulation as the siRNA delivery system. The obtained particle size and zeta potential values show that the chitosan coating process is an effective parameter for particle size and the zeta potential of liposomes. The liposome formulations loaded with siHIF1-α and siVEGF showed good stability and protected siRNA from serum degradation after 24-h of incubation. The expression level of VEGF mRNA was markedly suppressed in MCF-7 and MDA-MB435 cells transfected with chitosan-coated liposomes containing HIF1-α and VEGF siRNA, respectively (95% and 94%). In vitro co-delivery of siVEGF and siHIF1-α using chitosan-coated liposome significantly inhibited VEGF (89%) and the HIF1-α (62%) protein expression when compared to other liposome formulations in the MDA-MB435 cell. The co-delivery of siVEGF and siHIF1-α was greatly enhanced in the vitro gene silencing efficiency. In addition, chitosan-coated liposomes showed 96% cell viability. Considering the role of VEGF and HIF1-α in breast cancer, siRNA-based therapies with chitosan coated liposomes may have some promises in cancer therapy., (Copyright © 2014.

Coronary artery anomalies rarely detected in autopsy series and angiograms can be a component of complex malformations, besides, can be also associated with sudden cardiac death. Presented case was 22-year-old male, who had suddenly fainted during a football match played on artificial turf, he was transferred into the hospital, however had died during intensive care therapy. He had been evaluated by local prosecutor, and sent to our center for autopsy. At autopsy, internal macroscopic examination revealed absence of the right coronary artery. A total of two coronary artery ostia were observed. One of them originated from the left aortic sinus, and the other one stemmed from 8 mm above the sinotubular line. Besides, Chiari network formation was seen in the right atrium. This case with coronary artery anomaly associated with formation of Chiari network was discussed from the perspective of forensic medicine in the light of the literature information.

Unlabelled: Presented case was a 2-year-old baby girl who had been treated for nearly one year with the indication of multifocal epileptiform anomaly. She was found dead in her bed in morning hours, autopsy was planned after prosecutors investigation. On internal autopsy examination, shrinkage of gyral structures in the frontal, and parietal lobes of the left hemisphere, markedly enlarged sulci, and a hypoplastic appearance were noted. Histopathological examination revealed evidence of pneumonia, brain exposed microgyral formations, disordered cortical stratification, hypercellularity, dysmorphic neuronal structures, balloon cells with diagnosis of cortical dysplasia. Pneumonia was reported as a cause of death. We aimed to discuss in the light of the literature a case with cerebral hypoplasia which is rarely seen at forensic autopsies., Keywords: cerebral hypoplasia/dysplasia - autopsy - congenital malformation - sudden death.

Background/aims: The endocannabinoid system can exert beneficial effects on gastrointestinal inflammation, and cannabinoid receptor-2 (CB2) agonists may represent a new therapeutic approach in inflammatory bowel disease (IBD). A functional CB2 Q63R polymorphism (rs35761398) in the CNR2 gene has been shown to affect the immunomodulating properties of the CB2 receptor. We sought to investigate whether the functional CB2 Q63R polymorphism (rs35761398) is associated with IBD susceptibility in a Turkish clinical sample., Materials and Methods: A total of 202 IBD patients, comprising 101 Crohn's disease (CD) patients and 101 ulcerative colitis (UC) patients, and 101 healthy controls were included in the study. The CB2 Q63R polymorphism was genotyped using real-time PCR., Results: There were no significant differences in the genotype frequencies of the three study groups. The odds ratio of the minor Q allele for CD relative to the common R allele was not significant (OR =1.02, 95% CI =0.67-1.56, p=0.99). Similarly, the odds ratio of the minor Q allele for UC relative to the common R allele did not reach statistical significance (OR =1.10, 95% CI =0.72-1.68, p=0.75). Moreover, the genotype frequencies did not show any significant association with the disease extent in either CD (p= 0.71) or UC patients (p=0.59)., Conclusion: These pilot findings suggest that CB2 Q63R polymorphism does not play a major role in genetic susceptibility to IBD or in its disease phenotypes among Turkish subjects.
