Aim: The aim of this study was to evaluate transsphenoidal surgery results in acromegalic patients which were performed not by a single surgeon but by different surgeons. Methods: The study included 30 (M/F: 13/17) patients whose follow-up data were available. Basal or nadir postglucose growth hormone levels of less than 2 ng/ml were accepted as cure(More)
Fibrous dysplasia is a developmental disorder caused by abnormal proliferation and maturation of fibroblasts resulting in replacement of mature bone by structurally weak, immature woven bone. Clival involvement in monostotic fibrous dysplasia is extremely unusual, and has rarely been reported previously. We report a case of monostotic fibrous dysplasia of(More)
BACKGROUND Monocyte chemoattractant protein (MCP)-1 is suggested to be implicated in the pathogenesis of diabetic nephropathy by activating and recruiting monocytes to the glomerulus via regulation of adhesion molecule expressions. The aim of this study was to test potential associations between serum concentrations of MCP-1, monocyte expression of Mac-1(More)
BACKGROUND Gestational diabetes mellitus (GDM) is defined as glucose intolerance that has begun during pregnancy. Recent studies have proven that development of atherosclerosis may be established in this population even without presence of type 2 diabetes. For assessment of atherosclerosis, epicardial fat thickness (EFT) is recently being used as a(More)
Oxidative stress is thought to be one of the underlying mechanisms of diabetic microvascular complications such as diabetic nephropathy and diabetic retinopathy (DRP). Asymmetric dimethylarginine (ADMA) is an endogenous nitric oxide (NO) synthase inhibitor and increased by oxidative stress. Apelin is an endogenous ligand for human orphan G-protein-coupled(More)
Insulin resistance (IR) is one of the common features of the polycystic ovary syndrome (PCOS), and recent studies indicate the possible role of vitamin D in the pathogenesis of IR and glucose metabolism. Aim of this study was aimed to determine the effect of vitamin D replacement therapy on glucose metabolism, insulin, and androgen levels in obese,(More)
The aim of the study was to evaluate the effect of metformin on markers of endothelial function, vascular inflammation and factors of thrombosis in obese type 2 diabetic patients. Twenty-four type 2 diabetic patients (15 female, 9 male) previously under medical nutrition treatment (MNT)+regular exercise programme (REP) without chronic micro or macrovascular(More)
The aim of the study was to evaluate the long-term effect of rosiglitazone and metformin monotherapy with medical nutrition treatment (MNT) and of MNT alone on arterial stiffness, serum monocyte chemoattractant protein (MCP)-1 and matrix metalloproteinase (MMP)-9 in drug naive patients with type 2 diabetes mellitus. Fifty type 2 diabetic patients were(More)
Apart from fasting blood glucose (FBG) and insulin (FBI), oral glucose tolerance test (OGTT) is also used in calculating insulin sensitivity. During OGTT, insulin secretion may not reflect normal physiological insulin secretion. Based on this idea, hepatic and whole body insulin sensitivity rates were tested during OGTT and mixed meal test (MMT) in obese(More)
The tissue-irritating effect of anodyne medicaments was studied via enzyme histochemical evaluation of muscle tissue (screening test) and pulp tissue (usage test). Of the medicaments tested, formocresol was the most irritating, followed by Cresatin, eugenol, and oil of pimenta leaf. The effects of Cresatin, eugenol, and oil of pimenta leaf were not(More)
