Methods: The study included 70 pregnant women and their neonates.

Effect of renal failure on N-terminal Pro-Brain natriuretic peptide in patients admitted to emergency department with acute dyspnea.

Objective: Preexisting renal failure diminishes the excretion of N-Terminal Pro-Brain Natriuretic Peptide (NT-proBNP), therefore limits the diagnostic value of this peptide for concomitant heart failure. The aim of this study was to evaluate the association between NT-proBNP and the stages of renal dysfunction in a typical population attended to emergency department with acute dyspnea.

Methods: In this cross-sectional study, all consecutive patients with acute dyspnea underwent clinical evaluation, laboratory assessment of NT-proBNP, and echocardiographic examinations.

Postload hyperglycemia is associated with increased subclinical inflammation in patients with prediabetes.

Background/aims: In this present study, we aimed: (i) To clarify if prediabetes is associated with subclinical inflammation independent of underlying obesity, and (ii) to evaluate the effect of postload glucose concentration on subclinical inflammation markers in a group of patients with elevated fasting glucose.

Material And Methods: In a cohort of 165 patients with newly detected fasting hyperglycemia, according to 75 g oral glucose tolerance test (OGTT), subjects were classified either as newly diagnosed type 2 diabetes (diabetes group, n = 40), impaired fasting glucose (IFG) plus impaired glucose tolerance (IGT) (IFG/IGT group, n = 42) or IFG only (IFG group, n = 83). A control group (n = 47) consisted of age- and body mass index (BMI)-matched healthy subjects with a normal OGTT.

Vitamin D deficiency in pregnant women and their neonates in spring time in western Turkey.

Although Turkey is located in a sunny region, vitamin D deficiency is still a serious health problem in pregnant women and their infants, especially among the low socio-economic status Turkish population. This study was carried out in order to measure serum 25-hydroxyvitamin D3 [25(OH)D] concentrations of the pregnant women in the last trimester and in their neonates at delivery and to determine the factors associated with maternal serum 25(OH)D concentrations. Among the patients visiting the Ege Obstetrics and Gynecology Hospital in the period March to May 2008, 258 healthy pregnant women ≥37 weeks of gestation were included in this study.

The study included 127 AS patients (100M/27F) and 38 (27M/11F) controls. Spinal mobility was assessed by the bath ankylosing spondylitis metrology index (BASMI).

Quantifying the expression of VEGF using qRT-PCR, evaluation of MVD and their correlation with clinicopathological factors in laryngeal squamous cell carcinoma.

Objectives: In this study we quantified the expression of vascular endothelial growth factor (VEGF) using quantitative real-time polymerase chain reaction in laryngeal squamous cell carcinoma (LSCC) tissues and evaluated the correlation between the level of VEGF and microvessel density (MVD), and clinicopathological factors.

Patients And Methods: Twenty-seven patients with LSCC undergoing total or partial laryngectomy at the Ear, Nose, and Throat and Head and Neck Surgery Department of the Izmir Tepecik Training and Research Hospital between September 2006 and July 2008. There was no VEGF expression in two patients that were excluded from the study.

Evaluation of various endothelial biomarkers in ankylosing spondylitis.

Atherosclerosis has been shown to be increased in chronic inflammatory diseases including ankylosing spondylitis (AS). Impaired endothelial function, the first step in atherosclerosis, may be reflected by changes in various endothelial biomarkers of hemostasis and the release of several cellular adhesion molecules or cytokines. In this study, we investigated changes in the levels of various possible markers with regard to disease activity and treatment regimen with/without anti-TNF-α drugs.

Maternal and cord blood homocysteine and folic acid levels in smoking and nonsmoking pregnant women.

Introduction: The homocysteine level in blood is affected by gender, diet, smoking, folic acid and B-complex vitamins. It is known that higher than normal homocysteine levels in plasma may cause vascular endothelium dysfunction, resulting in the promotion of thrombus formation. In our study, we aimed to assess the effects of smoking during pregnancy on the homocysteine and folic acid levels of the mother and baby.

The role of heme in hemolysis-induced acute pancreatitis.

Background: The aim was to reveal the mechanism of hemolysis-induced acute pancreatitis and to evaluate the role of heme and heme oxygenase activity in inducing pancreatic inflammation in an experimental hemolysis model.

Material/methods: Hemolytic anemia was induced in rats by intraperitoneal injection of 60 mg/kg acetylphenylhydrazine (APH). To evaluate the toxic effect of free heme after hemolysis, heme oxygenase inhibitor (HOI) was used to inhibit the enzyme which decreases the free heme concentration after hemolysis.

The influence of marginal zinc deficient diet on post-vaccination immune response against hepatitis B in rats.

Aim: To evaluate in vitro T lymphocyte proliferation and specific antibody response to hepatitis B vaccination in two groups of rats fed with normal and marginal zinc content.

Methods: Twenty-two Wistar-Albino rats were randomly assigned into two groups and were fed with constant diet. Zinc was suplemented 10mg/kg dry weight in group I (marginal zinc content) (n=14) and 30mg/kg dry weight in group II (n=8).

Effects of common anti-epileptic drug monotherapy on serum levels of homocysteine, vitamin B12, folic acid and vitamin B6.

There is emerging evidence to support the unfavorable effects of some anti-epileptic drugs on the plasma homocysteine concentrations. Elevated homocysteine levels induced by anti-epileptic drug administration can theoretically increase not only the risk of vascular occlusive diseases, but also the risk of resistance to anti-epileptics and development of refractory epilepsy. To investigate the effect of common anti-epileptic drugs on the homocysteine metabolism, a total of 75 epileptic patients receiving phenytoin (n=16), carbamazepine (n=19), or valproic acid (n=22) and no anti-epileptic drug (n=18) were enrolled.

HLA genotypes in Turkish patients with myasthenia gravis: comparison with multiple sclerosis patients on the basis of clinical subtypes and demographic features.

The nature and intensity of the association of myasthenia gravis (MG) with distinct human leukocyte antigens (HLA) haplotypes differ between ethnic populations. The aims of the present study were to examine the relationship between HLA class I and II haplotypes and MG; to show the HLA associations with various MG subsets; and to investigate the association between MG and clinical subgroups of multiple sclerosis (MS) regarding HLA haplotypes. A total of 66 patients with MG were enrolled onto the study.

Free carnitine levels in children with steroid-sensitive nephrotic syndrome.

Background: Carnitine transports long-chain fatty acids across the inner mitochondrial membrane. Carnitine metabolism is disturbed in some renal diseases, such as chronic renal failure. Previous studies have shown that children had normal serum free carnitine (FC) and total carnitine levels in idiopathic nephrotic syndrome, IgA nephropathy, non-IgA nephropathy and focal segmental glomerulosclerosis.

Effect of hemodialysis on carnitine levels in children with chronic renal failure.

Background: Impaired structural and metabolic integrity of the kidney in chronic renal failure (CRF) effects carnitine metabolism by means of many factors. Depletion due to hemodialysis (HD) is one of the major concerns. The aim of the study was to investigate the effects of chronic renal failure and HD on plasma free carnitine (FC) concentrations in children.

Myocardial and hepatic free carnitine concentrations in pups of diabetic female rats.

Background/aims: Adequate carnitine levels are required for normal fatty acid and energy metabolism in heart muscle. It is well known that streptozotocin-induced diabetic rats develop myocardial carnitine deficiency and that carnitine therapy may be beneficial to the diabetic heart. Infants of diabetic mothers (IDM) are known to be at risk for developing a hypertrophic type of cardiomyopathy.
