Background: Repeated implantation failure (RIF) is the main problem after using assisted reproductive techniques (ART). The main causes of RIF as a multifactorial problem including decrease in endometrial receptivity, defects of embryo or combinational. Successful embryo implantation depends on trophoblast proliferation, migration and invasion to the endometrium, all of which are associated wit...

BACKGROUND 5-lipoxygenase protein (ALOX5AP) has been recognized as a susceptibility gene for stroke and coronary artery diseases. The present study was to explore the role of this gene in the eastern Chinese patients with ischemic stroke. METHODS Using a case-control design, we studied 658 patients with ischemic stroke and 704 unrelated population-based controls who were age- and sex-matched....

Hardy-Weinberg equilibrium (HWE) holds when, in a closed population with random mating and without mutation and natural selection, genotype frequencies at any locus is a simple function of allele frequencies. Testing for HWE is now a common practice in population genetics and genetic association studies of non-communicable diseases; however, it is less-regarded, or sometimes miss-interpreted, i...

OBJECTIVE Hypertension (HTN) is the most common cardiovascular disease and is assuming epidemic proportions in developing countries. Genetic and environmental factors play important role in the development of hypertension.The objective of this study was to investigate the possible association of ACE, FABP2, PPARG2, GST, FTO and CYP46A1 genes polymorphism and susceptibility of individuals to HTN...

Estimation of short tandem repeat (STR) multilocus genotype frequencies for the identification of individuals and estimation of allele frequencies for parentage assignment both depend on (a) testing a lot of loci, (b) high levels of polymorphism at each locus tested, and (c) independence among alleles. Independence is critical, because the estimation of multilocus genotype and gamete frequencie...

It is well known that aspirin-exacerbated respiratory disease (AERD) is more common in women than in men, however, whether gene polymorphisms of the thromboxane A2 receptor (TBXA2R) and chemoattractant receptor-homologous molecules expressed on Th2 cells (CRTH2) are associated with the susceptibility of AERD remains unknown. In this study, we examined the gene polymorphisms in a Japanese popula...

BACKGROUND To investigate the relationship of five TP53 polymorphisms (p.P47S, p.R72P, PIN3 ins16bp, p.R213R and r.13494g>a) with the esophageal cancer (EC) risk in North Indians. MATERIALS AND METHODS Genotyping of p.P47S, p.R72P, PIN3 ins16bp, p.R213R and r.13494g>a polymorphisms of TP53 in 136 sporadic EC patients and 136 controls using polymerase chain reaction and PCR-RFLP. RESULTS The...

osteoporosis is a metabolic bone disease affecting mostly elderly women. as metabolizing enzymes, the roles of few cytochromes have been studied in osteoporosis development. the aim of this study was to assess for the first time the association of cyp2e1 and cyp1a1 polymorphisms and osteoporosis in postmenopausal women. 112 postmenopausal women presenting osteoporosis and 93 age and sex matched...
