Filter by:To evaluate differences in specific SNPs and intestinal microflora between patients with gout and hyperuricemia and healthy controls.
The project was aimed to explore the associations of single nucleotide polymorphisms (SNPs) of vitamin D receptor gene with specific circulating lipids in adult Chinese. The circulating 25-hydroxyvitamin D concentration was also tested to explore its interactions with SNPs in the associations.
Obstructive Sleep Apnea (OSA) is associated with increased oxidative stress. The major sources of Reactive Oxygen Species (ROS) in the vasculature are the NADPH oxidases. Several polymorphisms related to NADPH oxidase expression or NADPH oxidase activity has been identified. The investigators are going to compare the distribution of the allelic frequencies of A-930G and C242T polymorphisms and their possible relationship with the levels of 8-isoprostanes as a marker of oxidative stress in patients with OSA and in a control group without OSA.
This pilot study is designed to investigate differences in folate-related genes (single nucleotide polymorphisms) and their relationship to the species of folate present on red blood cells.
NFKB1 -94ins/del polymorphism has been reported to be associated with reduced promoter activity of NFKB1 and several clinical diseases, but the clinical results cannot always be replicated. Besides, mutate allele is associated with alleviated inflammation in ulcerative colitis and some tumors, but aggravated inflammation in ARDS. The clinical value of this polymorphism remains controversial. This study was performed to investigate the association of NFKB1 -94ins/delATTG polymorphism with lung and/or kidney injury after cardiac surgery with CPB.
Background: Infertility affects up to 15% of married couples. About half are attributable to female factors, among which anovulation is the leading cause. Some 5% of all women of reproductive age are anovulatory due to the polycystic ovarian syndrome (PCOS). PCOS causes also major health and cosmetic problems and significantly affects quality of life. PCOS is associated with cardiovascular morbidity and Type 2 diabetes mellitus, but it is unclear whether these are caused by the ovarian dysfunction or result from a common denominator. Working hypothesis and aims: Whole genome analysis of multigenerational families in which at least one woman is affected by PCOS may significantly reduce the numbers needed to verify the specific genes, involved in the causation of PCOS. Methods: Registration of multigenerational families and production of personal files with full workup for the presence of PCOS or its absence (in the women participants). Drawing of blood, extraction and preservation of DNA. Analysis of all informative SNPs in the genomes of the participants on a specific microarray chip. Statistical analysis of the results. Expected results: Verification of the loci and putative genes, associated with the appearance of PCOS. Importance: Elucidation of the specific genes underlying the pathology of PCOS. Probable implications to Medicine: Paving the way for targeted treatment of the problems, associated with PCOS, based on the clear knowledge of its underlying cause(s).
The 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors, also known as statins, played an important role in lipid-lowering therapy and reduction of cardiovascular risks. However, it has been observed that the response to statin therapy varies from patient to patient, and gene polymorphism could have contributed to the variation.
