Abstract
Ankylosing spondylitis (AS) is a chronic inflammatory disease. In many inflammatory diseases, increased production of pro-inflammatory cytokines is associated with an increase in oxidative stress mediators. Thiol/disulfide homeostasis is a marker for oxidative stress. The aim of this study was to examine the dynamic thiol/disulfide homeostasis in AS. Sixty-nine patients with AS and 60 age- and sex-matched controls were included in the study. The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and visual analogue scale (VAS) were used to determine the disease activity. Native thiol, total thiol, and disulfide levels were measured with a novel automated method recently described by Erel and Neselioglu. The aforementioned method is also optionally manual spectrophotometric assay. The total thiol levels were significantly lower in the AS group compared with the control group (p = 0.03). When the patients were divided into active (n = 35) and inactive (n = 34) subgroups using BASDAI scores, the native plasma thiol and total thiol levels were significantly lower in the active AS patients compared to the inactive AS patients (p = 0.02, p = 0.03 respectively). There was a negative correlation between the plasma native thiol levels and VAS, BASDAI scores. Thiol/disulfide homeostasis may be used for elucidating the effects of oxidative stress in AS. Understanding the role of thiol/disulfide homeostasis in AS might provide new therapeutic intervention strategies for patients.

Abstract
There have been few studies concerning the cytokine profiles in gastric mucosa of Helicobacter pylori-infected patients with normal mucosa, chronic gastritis, and gastric carcinoma (GAC).In the present study, we aimed to elucidate the genomic expression levels and immune pathological roles of cytokines-interferon (IFN)-γ, tumor necrosis factor (TNF)-α, interleukin (IL)-4, IL-6, IL-10, transforming growth factor (TGF)-β, IL-17A, IL-32-in H pylori-infected patients with normal gastric mucosa (NGM; control), chronic active gastritis (CAG), and GAC. Genomic expression levels of these cytokines were assayed by real-time PCR analysis in gastric biopsy specimens obtained from 93 patients.We found that the genomic expression levels of IFN-γ, TNF-α, IL-6, IL-10, IL-17A mRNA were increased in the CAG group and those of TNF-α, IL-6, IL-10, IL-17A, TGF-β mRNA were increased in the GAC group with reference to H pylori-infected NGM group.This study is on the interest of cytokine profiles in gastric mucosa among individuals with normal, gastritis, or GAC. Our findings suggest that the immune response of gastric mucosa to infection of H pylori differs from patient to patient. For individual therapy, levels of genomic expression of IL-6 or other cytokines may be tracked in patients.

Abstract
BACKGROUND AND PURPOSE A number of recent studies have described malformations of cortical development with mutations of components of microtubules and microtubule-associated proteins. Despite examinations of a large number of MRIs, good phenotype-genotype correlations have been elusive. Additionally, most of these studies focused exclusively on cerebral cortical findings. The purpose of this study was to characterize imaging findings associated with disorders of microtubule function. MATERIALS AND METHODS MRIs from 18 patients with confirmed tubulin mutations (8 TUBA1A, 5 TUBB2B, and 5 TUBB3) and 15 patients with known mutations of the genes encoding microtubule-associated proteins (5 LIS1, 4 DCX, and 6 DYNC1H1) were carefully visually analyzed and compared. Specific note was made of the cortical gyral pattern, basal ganglia, and white matter to assess internal capsular size, cortical thickness, ventricular and cisternal size, and the size and contours of the brain stem, cerebellar hemispheres and vermis, and the corpus callosum of patients with tubulin and microtubule-associated protein gene mutations. Results were determined by unanimous consensus of the authors. RESULTS All patients had abnormal findings on MR imaging. A large number of patients with tubulin gene mutations were found to have multiple cortical and subcortical abnormalities, including microcephaly, ventriculomegaly, abnormal gyral and sulcal patterns (termed "dysgyria"), a small or absent corpus callosum, and a small pons. All patients with microtubule-associated protein mutations also had abnormal cerebral cortices (predominantly pachygyria and agyria), but fewer subcortical abnormalities were noted. CONCLUSIONS Comparison of MRIs from patients with known mutations of tubulin genes and microtubule-associated proteins allows the establishment of some early correlations of phenotype with genotype and may assist in identification and diagnosis of these rare disorders.

Abstract
Objective.To assess the performance of the new 2012 provisional European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) polymyalgia rheumatica (PMR) clinical classification criteria in discriminating PMR from other mimicking conditions compared with the previous 5 diagnostic criteria in a multicenter prospective study.Methods.Patients older than 50 years, presenting with new-onset bilateral shoulder pain with elevated acute-phase reactants (APR), were assessed for the fulfillment of the new and old classification/diagnostic criteria sets for PMR. At the end of the 1-year followup, 133 patients were diagnosed with PMR (expert opinion) and 142 with non-PMR conditions [69 rheumatoid arthritis (RA)]. Discriminating capacity, sensitivity, and specificity of the criteria sets were estimated.Results.Discriminating capacity of the new clinical criteria for PMR from non-PMR conditions and RA as estimated by area under the curve (AUC) were good with AUC of 0.736 and 0.781, respectively. The new criteria had a sensitivity of 89.5% and a specificity of 57.7% when tested against all non-PMR cases. When tested against all RA, seropositive RA, seronegative RA, and non-RA control patients, specificity changed to 66.7%, 100%, 20.7%, and 49.3%, respectively. Except for the Bird criteria, the 4 previous criteria had lower sensitivity and higher specificity (ranging from 83%–93%) compared with the new clinical criteria in discriminating PMR from all other controls.Conclusion.The new 2012 EULAR/ACR clinical classification criteria for PMR is highly sensitive; however, its ability to discriminate PMR from other inflammatory/noninflammatory shoulder conditions, especially from seronegative RA, is not adequate. Imaging and other modifications such as cutoff values for APR might increase the specificity of the criteria.

Abstract
Arenaviruses such as Lassa virus (LASV) can cause severe hemorrhagic fever in humans. As a major impediment to vaccine development, delayed and weak neutralizing antibody (nAb) responses represent a unifying characteristic of both natural infection and all vaccine candidates tested to date. To investigate the mechanisms underlying arenavirus nAb evasion we engineered several arenavirus envelope-chimeric viruses and glycan-deficient variants thereof. We performed neutralization tests with sera from experimentally infected mice and from LASV-convalescent human patients. NAb response kinetics in mice correlated inversely with the N-linked glycan density in the arenavirus envelope protein’s globular head. Additionally and most intriguingly, infection with fully glycosylated viruses elicited antibodies, which neutralized predominantly their glycan-deficient variants, both in mice and humans. Binding studies with monoclonal antibodies indicated that envelope glycans reduced nAb on-rate, occupancy and thereby counteracted virus neutralization. In infected mice, the envelope glycan shield promoted protracted viral infection by preventing its timely elimination by the ensuing antibody response. Thus, arenavirus envelope glycosylation impairs the protective efficacy rather than the induction of nAbs, and thereby prevents efficient antibody-mediated virus control. This immune evasion mechanism imposes limitations on antibody-based vaccination and convalescent serum therapy. Neutralizing antibodies (nAbs) represent a key principle of antiviral immunity. Protective vaccines aim at inducing nAbs to prevent viral infection, and infusion of nAbs in convalescent patient serum can offer a potent antiviral therapy. Certain viruses, however, have found ways to evade nAb control. Amongst them are high-risk pathogens of the arenavirus family such as Lassa virus (LASV), which is a frequent cause of hemorrhagic fever in West Africa. Here we unveil the molecular strategy by which arenaviruses escape antibody neutralization and avoid efficient immune control. We show that their surface is decorated with sugar moieties, serving to shield the virus against the neutralizing effect of the host’s antibodies. This immune evasion strategy differs from those described for other viruses, in which sugars impair primarily the induction of antibodies or allow for viral mutational escape. The arenavirus sugar coat renders the host nAb response inefficient and as a consequence thereof, the host fails to promptly control the infection. Our results offer a compelling explanation for the long history of failures in trying to make a nAb-based vaccine against LASV or in using convalescent serum for therapy. These mechanistic insights will support vaccine development efforts against arenaviruses such as LASV.

Abstract
Inflammatory myopathies are a heterogeneous group of diseases with unknown etiology characterized by inflammation of the skeletal muscles and proximal muscle weakness. Dermatomyositis (DM) is an idiopathic inflammatory myopathy with characteristic cutaneous findings such as heliotrope rash, Gottron's sign, Gottron's papules, shawl sign and machinist hand. Amyopathic dermatomyositis (ADM) is a rare but well-recognized clinical subtype of DM, constituting aproximately 10-20% of patients with this disease. It generally manifests only pathognomonic skin findings without clinical and laboratory evidence of muscle involvement. In this report, we present a rare case of ADM associated with interstitial pulmonary disease.

Abstract
BACKGROUND There is growing consensus in the literature that inflammation plays a central role in the pathophysiology of obesity and type 2 diabetes mellitus (T2DM) and cardiovascular complications. Neutrophil-to-lymphocyte ratio (NLR) provides a simple method for assessment of inflammatory status and it is a new, inexpensive marker. The aim of the present study was to investigate the predictive value of preprocedural (before the OGTT) NLR on development of type 2 diabetes (T2DM) in morbid obesity patients (MOP). METHODS 306 MOP (body mass index ≥ 40 kg/m(2)) and 95 normal weight patients with normal OGTT [fasting plasma glucose (FPG)<100mg/dL. Two-hour glucose during OGTT<140 mg/dL] were evaluated in this study. RESULTS The mean ± SD NLR of MOP was significantly higher than that of patients with normal weight healthy patients (3.67 ± 0.95 vs. 1.82 ± 1.02, P<0.001, respectively). In receiver operating characteristics curve analysis, NLR>3.12 had 79.2% sensitivity and 64.9% specificity in predicting T2DM. Logistic regression analysis showed that elevated NLR (OR: 2.577, 95% CI: 1.363-4.872, P=0.004) was an independent variable for predicting T2DM in MOP. CONCLUSIONS MOP have higher NLR than healthy controls. High NLR is a powerful and independent predictor of T2DM in MOP. Elevated NLR levels are usually considered as an inflammatory marker. The results of this study suggested that inflammation plays a role in the pathogenesis of T2DM with MOP.

Abstract
OBJECTIVE The criterium defining the threshold size of adrenal incidentaloma (AI) is a size greater than 1 cm diameter. However, data concerning AI≤1 cm in diameter is scant. The aim of this study was to evaluate the function of adrenal masses≤1 cm and to compare them with adrenal masses>1 cm. MATERIALS AND METHODS The study included 130 consecutive patients with AI (38 and 92 AI at ≤ 1 cm and > 1 cm, respectively). The patients were evaluated according to demographic and hormonal characteristics. RESULTS The prevalence of SCS was 5.3 and 12% in AI≤1 cm and > 1 cm diameter, respectively. Hyperaldosteronism was found only in patients with > 1 cm AI. Pheochromocytoma were not found in either group. Patients with > 1 cm AI had a higher prevalence of SCS and primary hyperaldosteronism than patients with ≤ 1 cm AI, but the difference was not significant. The prevalence of diabetes and hypertension was high both in non-functional AI with ≤ 1 cm and > 1 cm patients and showed no significant difference between the 2 groups. CONCLUSION Our study is the first to focus on the clinical and hormonal characteristics of patients with ≤ 1 cm AI. Those with AI≤1 cm harboured SCS, as was the case for AI>1 cm. Similar to AI>1 cm, non-functional AI≤1 cm also had a higher prevalence of diabetes and hypertension.

Abstract
AIM Nesfatin-1 was recently discovered anorexigenic peptide in the brain which is derived from nucleobindin-2. Central and peripheral administration of nesfatin-1, inhibits food intake, dose-dependently. Hyperthyroid patients have increased appetite and food intake with a craving for carbohydrate-rich food, at the beginning of disease, but the physiological mechanisms underlying this behavior is not known exactly. In this study, we investigated whether nesfatin-1 is involved in the regulation of appetite and body weight in hyperthyroidism, or not. METHODS A total of 70 patients with subclinical (35) and overt hyperthyroidism (35) compared with 35 control patients. Serum nesfatin-1 level was measured from all samples by commercial ELISA kit. RESULTS Serum nesfatin-1 levels were similar between three groups (P=0.293). After adjusting for age and body mass index, nesfatin-1 levels in control group was not different from subclinical and overt hyperthyroid group, respectively (P=0.567 and P=0.519). CONCLUSION These data showed that serum nesfatin-1 levels do not significant change in overt and subclinical hyperthyroidism.

Abstract
AIM We evaluated the prognostic significance of preoperative serum albumin value and metastatic lymph node ratio for gastric cancer patients. METHODS We studied patients diagnosed with gastric carcinoma in the first Department of Surgery, Bezmialem Vakif Gureba Training and Research Hospital between January 2004 and December 2010; the patients were studied retrospectively. RESULTS A total of 67 patients with a mean age of 58.7 ± 11.4 years were included in the study. The majority of patients were male (N.=53 male; N.=14 female). Most patients were in an advanced stage of the disease (stage III-IV) on admission (67.2%). We classified patients according to albumin value as "normal" Group 1 (83%) and "hypoalbuminemic" Group 2 (17%). With albumin, age, resection type, perineural invasion, and ratio of metastatic lymph nodes, T and TNM stages were significant predictors of cancer-specific survival. CONCLUSION As a result, irrespective of mechanism, pre-operative evaluations of albumin and metastatic lymph node ratio should be performed to stratify the patients for risk analysis and prognosis. A level less than 3.5 g/dL is a negative prognostic factor for resectable gastric cancers.

Abstract
OBJECTIVE Contrast-induced acute kidney injury (CI-AKI) is a common complication in patients with acute ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). The Mehran risk score was defined originally in elective PCI and may be predictive of CI-AKI. The aim of the present study was to investigate whether the Zwolle score predicts CI-AKI in patients with acute STEMI undergoing primary PCI. PATIENTS AND METHODS We analyzed the data of 314 consecutive patients (mean age 56.3 ± 11.4 years) with acute STEMI undergoing primary PCI. The study population was divided into two groups according to CI-AKI development. The Mehran score, Zwolle score, baseline characteristics, and in-hospital outcomes were recorded. RESULTS Patients with CI-AKI had higher Mehran and Zwolle scores. In a receiver operating characteristic (ROC) curve analysis, high area under the curve (AUC) values were determined for Zwolle and Mehran scores (0.85 and 0.79, respectively) for CI-AKI development. A Zwolle score greater than 2 predicted CI-AKI with a sensitivity of 76.3 % and a specificity of 75.4 %. A Mehran score greater than 5 predicted CI-AKI with a sensitivity of 71.1 % and a specificity of 73.6 %. CONCLUSION Zwolle score predicts CI-AKI slightly better than the Mehran score in patients with STEMI undergoing primary PCI. This simple score can be used at the catheterization laboratory for risk stratification for the development of CI-AKI.
