Background and purpose: Oral squamous cell carcinoma (OSCC) is the most common tumor of the head and neck. XRCC1 is a DNA repair gene and there are controversies about the association between XRCC1 gene polymorphism (RS1799782) in pathogenesis and susceptibility to OSCC. The purpose of this study was to investigate the association between XRCC1 (rs1799782) gene polymorphism and its dominant all...

Background and Objective: Alopecia Areata (AA) is a multifactorial disease characterized by hair loss especially from the scalp affecting approximately 5.3 million people. Since major histocompatibility complex (HLA) region is considered to be associated with AA susceptibility, the effect of HLA-DQB1*3 allele frequency was investigated in the present study in AA patients and their respective co...

Background: Adiponectin, an adipocyte-secreted hormone, is known to have anti-atherogenic, anti-inflammatory, and anti-diabetic properties. In the present study, the association between two common single nucleotide polymorphisms (SNPs) (+45T/G and +276G/T) of ADIOPQ gene and coronary artery disease (CAD) was assessed in the subjects with type 2 diabetes (T2DM). Methods: Genotypes of two SNPs we...
