BackgroundAttention deficit hyperactivity disorder (ADHD), is a multifactorial disorder and converging evidence has implicated abnormalities of dopamine neurotransmission. The aim of this study was to examine the association of -141 polymorphisms in DRD2 gene with ADHA among Iranian-Azeri population.Materials and Methods A case–control association study included 153 patients with attention defi...

promoter polymorphism of cytokine genes may lead to inter-individual differences in cytokine levels, therefore, polymorphisms may associate with susceptibility to infectious diseases. in this study, we investigated a possible association between interleukin-10 (il-10) -1082a⁄g (rs1800896) and interferon (ifn)-gamma +874t/a (rs2430561) promoter polymorphisms and tuberculosis (tb) in the azeri po...

abstract background and purpose: overweight and obesity are the health problem in adolescents and the main purpose of this study was to evaluate this problem and some socio-demographicrelated factors among two ethnic groups in iranian northern primary school children in 2010. materials and methods: this was a descriptive and cross-sectional study that performed on 4165 students (turkman = 2852a...

Genetically, every individual is unique; this may stem from inheritance, geographical locations, and/or environmental interactions. This study examined the possibility of developing a cheap and easy-to-use marker that can distinguish among the three ethnic groups in Nigeria using RAPD-PCR. Five RAPD primers, OPA1-3 and OPC1-2, were randomly selected and used to amplify DNA samples isolated from...

Background:Many case-control investigations have showed the correlation of TP53 gene polymorphisms with the risk of breast cancer. However, the findings are not consistent. It has been suggested that the investigation of P53 genotype combinations and haplotypes may be more helpful than the detection of single polymorphisms. In the present study, we investigate...
