Aim: Non-alcoholic steatohepatitis is one of the most common causes of chronic liver disease and the incidence in the population varies from %10–24. TGF- β –1 is the most important TGF- β isoform responsible for fibrosis and its effect on hepatic fibrosis was demonstrated in-vitro and in chronic viral hepatitis. Besides TGF- β is an immunsuppresive cytokine and it is known that low TGF- β activity can trigger autoimmune diseases and inflammation.<...

Introduction: Although the etiology of osteoporosis is different between men and women, the underlying pathophysiologic mechanism is similar, namely an absolute or relative increase in bone resorption, leading to progressive bone loss. Transforming growth factor (TGF) beta-1 is a growth factor in human bone, which is produced by osteoblasts and inhibits osteoclast proliferation and activity and stimulates proliferation and differentiation of preosteoblasts.<p class="abstex...

The kisspeptins are KiSS-1 gene-derived peptides which signal through the G protein coupled receptor 54 (GPR54), and have recently been shown to be critical regulators of reproduction. Acute intracerebroventricular (ICV) or peripheral administration of kisspeptin to rodents and primates, and peripheral administration to humans, stimulates the hypothalamic-pituitary gonadal (HPG) axis. This effect is thought to be mediated via the hypothalamic gonadotrophin-releasing hormone (G...

Recently, we have reported a few cases of acute liver damage in patients with Graves’ ophthalmopathy (GO), during or following high dose intravenous (iv) glucocorticoid (GC) pulse therapy. In the present study we analyzed retrospectively liver enzymes (LE) in 294 consecutive patients with GO who underwent ivGC. LE were measured before or during ivGC, and in 91 patients also within 6 months after ivGC. An asymptomatic increase in LE (AST peak: 67–88 U/L, ALT peak: 75&...

Alpha melanocyte stimulating hormone (alpha-MSH) is an agonist at the melanocortin 3 receptor (MC3-R) and MC4-R and stimulates corticosterone release from rat and human adrenal cells. Patients with Cushing's syndrome have elevated levels of serum alpha-MSH. Agouti related protein (AgRP) is an endogenous antagonist at the MC3-R and MC4-R and is expressed in the rat adrenal cortex. AgRP antagonises alpha-MSH-induced corticosterone release from rat and bovine adrenal cells. This ...

Objectives: To investigate whether there is a sex difference in serum leptin concentration in Chinese Type 2 diabetic patients with and without nephropathy.Methods: Early morning fasting serum leptin concentrations were measured in 34 Type 2 diabetic patients (mean age 62.1) with nephropathy (creatinine 120-450micromol/l and spot urinary albumin creatinine ratio (ACR) > 25 mg/mmol), 12 newly diagnosed diabetic subjects (mean age 62.5) with normoalbumi...

Background: The complex involvement of multiple metabolic defects in the pathogenesis of type 2 diabetes mellitus (T2DM) makes difficult the treatment in monotherapy, therefore, the use of different antidiabetic drugs with different and complementary mechanisms of action could result in better glycemic control with favorable metabolic changes.Objective: To determine the effectiveness and safety of the addition of a sodium-glucose co-transporter type 2 in...

Background: Cross-sex hormone therapy (CHT) is known to lead to alterations in cardiovascular risk factor(CVRF).Objective: To assess changes in lipid profile and other CVRF in transsexual subjects receiving CHT.Materials and methods: Retrospective longitudinal study. We evaluated individuals with gender identity disorder following CHT, assisted in the Gender Identity Unit from 2015 to 2017. Primary endpoint was lipid profile change...

BackgroundTo date, available animal models have failed to replicate the complex pathophysiology of chronic diabetic wounds. In a recent study we administered a regimen of antioxidant enzyme inhibitors (AIE) to develop a reliable and effective murine model. Here we use this model to test the efficacy of an amniotic membrane (AM) scaffold.Methods30 db/db mice received a pre-established AIE regimen and a 1 &#215...

Fc Receptor-like (FCRL) genes play a role in the immune system by encoding proteins that function as receptors on the surface of immune cells. Peripheral blood B cells, which are positive for FCRL3 and FCRL4, are rarely found in healthy individuals. In previous studies overexpression of FCRL4 was observed in patients with Graves’ disease (GD) but without association with thyroid peroxidase (TPOAb) or thyroglobulin (TgAb) antibodies. Nonetheless, the clinical significance ...
