Background: To determine the role of E-selectin gene S128R polymorphism on the enlargement of renal cysts in patients with polycystic kidney disease (PKD).

Minor variant of AHSG gene 767C>G polymorphism may decrease the risk of gestational diabetes mellitus.

Insulin resistance plays a central role in the development of gestational diabetes mellitus (GDM). The fetuin A molecule, of which serum level increases during pregnancy, is an inhibitor of insulin receptor tyrosine kinase and it is associated with insulin resistance. The aim of this study is to research the relationship of -843A>T (rs2248690) and 767C>G (rs4918) polymorphisms in the alpha-2-Heremans Schmid glycoprotein (AHSG) gene which is responsible for the synthesis of fetuin A and its association with (GDM).

The Possible Role of XRCC1 Gene Polymorphisms with Idiopathic Non-obstructive Azoospermia in Southeast Turkey.

Purpose: X-ray repair cross-complementing group 1 (XRCC1) plays a role in repairing DNA damage during spermatogenesis. We examined the effects the possible role of two single nucleotide polymorphisms of XRCC1 Arg194Trp and Arg399Gln in DNA repair gene XRCC1 with risk of idiopathic non-obstructive azoospermia (INOA) in a south-east Turkey population.

Materials And Methods: The genotype and allele frequencies of two observed polymorphisms of XRCC1 Arg194Trp and Arg399Gln were examined by polymerase chain reaction-restriction fragment length polymorphism in 102 infertile men with INOA and 102 fertile controls.

Cytogenetic screening in couples with Habitual Abortions.

Objective: Habitual abortion (HA) is defined at least three consecutive pregnancy losses. One of the etiologic causes is parental chromosomal anomalies. In this study, we aimed to that investigate the effect of parental chromosomal abnormalities on HA.

miRNA-mediated apoptosis activation through TMEM 48 inhibition in A549 cell line.

Lung has critic function in gas exchange, supplying oxygen to all cells. Rapid metastasis and the high rate of mortality characterises lung cancer. There are two types of this disease, small cell and non-small cell, which differs from each other according to histopathologic features.

Serum ICAM-1 level and ICAM-1 gene 1462A>G (K469E) polimorphism on microalbuminuria in nondiabetic, nonhypertensive and normolipidemic obese patients: Genetical background of microalbuminuria in obesity.

Background: A growing body of evidence suggest that obese individuals are under risk of renal parenchymal disorders when compared to nonobese counterparts. Microalbuminuria is the early marker of renal involvement. Although most of obese patients carries multiple risk factors for microalbuminuria, some obese individuals without risk factor may progress to microalbuminuria.

Prevalence of thromogenic gene mutations in women with recurrent miscarriage: A retrospective study of 1,507 patients.

Objective: Thromogenic gene mutations has been thought to be associated with recurrent pregnancy loss in women in Turkey. The aim of this study was to investigate the prevalence of thromogenic gene mutations such as factor V Leiden (FVL, G1691T), prothrombin (G20210A), and the methylene tetrahydrofolate reductase (MTHFR, C677T) mutation in women with recurrent pregnancy loss.

Methods: This descriptive study was carried out in the Department of Obstetrics and Gynaecology, Harran University School of Medicine, and included a total of 1,507 women with histories of recurrent pregnancy loss between January 2010 and June 2013.

Lack of Association between PTPN22 Gene +1858 C>T Polymorphism and Susceptibility to Generalized Vitiligo in a Turkish Population.

Background: Vitiligo is an autoimmune polygenic disorder characterized by loss of pigmentation due to melanocyte destruction. The PTPN22 gene +1858 C>T single nucleotide polymorphism (rs2476601) has been shown to be associated with various autoimmune disorders.

Objective: The aim of this study was to investigate whether the PTPN22 gene +1858 C>T single nucleotide polymorphism is associated with susceptibility to generalized vitiligo in a Turkish population.

Prenatal diagnosis of 4p and 4q subtelomeric microdeletion in de novo ring chromosome 4.

Ring chromosomes are unusual abnormalities that are observed in prenatal diagnosis. A 23-year-old patient (gravida 1, para 0) referred for amniocentesis due to abnormal maternal serum screening result in the 16th week of second pregnancy. Cytogenetic analysis of cultured amniyotic fluid cells revealed out ring chromosome 4.

The association of endothelial nitric oxide synthase gene G894T polymorphism and serum nitric oxide concentration with microalbuminuria in patients with gestational diabetes.

Aim: Gestational diabetes mellitus (GDM) is a glucose intolerant condition that affects 14% of all pregnancies. Diabetes mellitus (DM) occurs in 30 - 70% of patients with GDM after delivery. DM and GDM are associated with structural and functional deterioration of the renovascular system.

A case of complete tetraploidy in amniocentesis with normal karyotype in subsequent cordocentesis.

We report a case of complete tetraploidy in amniotic fluid culture obtained at 17 wk of pregnancy. Amniocentesis was performed in this pregnancy because of a high-risk maternal serum screening result and abnormal ultrasound findings. Amniotic fluid was cultured in two flasks.

Tuberous sclerosis presented with polycystic kidney disease and acute renal failure.

Tuberous sclerosis complex (TSC) is an autosomal dominant disorder characterized by hamartomatous involvement of multiple organs such as the skin, central nervous system, kidneys, lungs, and heart. A linkage has been found with a locus on the long arm of chromosome 9 (9q34) and with a locus on the short arm of chromosome 16 (16p13). TSC has a birth incidence of 1/6000.

Parental decisions regarding a prenatally detected fetal chromosomal abnormality and the impact of genetic counseling: an analysis of 38 cases with aneuploidy in Southeast Turkey.

Between 2004 and 2007, 1068 amniocentesis tests were performed in the Medical Biology and Genetic Department Laboratory at Dicle University. Aneuploidy was found in 38 cases (3.

Phospholipid and triacylglycerol fatty acid composition of major life stages of sunn pest, Eurygaster integriceps (Heteroptera: Scutelleridae).

Phospholipid and triacylglycerol fatty acid compositions of whole animals from all life stages of Eurygaster integriceps, including eggs, nymphs, pre-diapausing adults and diapausing adults, were determined. The fatty acid composition of total lipids of their food, wheat, was also determined. The major components of the insects and their food were the expected C16 and C18 saturated and unsaturated fatty acids.
