Peritoneal dialysis fluid biocompatibility impact on human peritoneal membrane permeability.

Background: We have compared the effects of conventional lactate-based peritoneal dialysis fluid (CPDF) with respect to bicarbonate/lactate-based fluid on peritoneal ultrafiltration (UF) and peritoneal permeability, and on variations on gene expression in cells isolated from effluents of patients' peritoneal bags.

Methods: This was a non-randomized sequential prospective study including all incident peritoneal dialysis (PD) patients ( = 40) recruited in our centre. Peritoneal equilibration tests (PETs) were performed using CPDF or BPDF both containing 2.

Paraoxonase 1 and 2 gene variants and the ischemic stroke risk in Gran Canaria population: an association study and meta-analysis.

Purpose Of The Study: The present study aims to evaluate the relationship between rs662 (Gln(Q)192Arg(R)) and rs854560 (L55M) and the rs7493 (S311C) in the paraoxonase genes and ischemic stroke (IS) in the population of Gran Canaria (Canary Islands). The association with stroke was also evaluated using systematic review and meta-analysis.

Methods: A total of 129 IS patients and 176 age and gender matched controls were enrolled.

[Update on the genetics of stroke].

Stroke is a disease with significant morbidity, mortality, and economic and social impacts. It is a complex entity whose pathogenesis involves multiple environmental and genetic factors, with the latter having a role in up to 50% of strokes. The objective of the review is to analyze the available methods for the genetic diagnosis including linkage studies of variation in copy number, gene - candidate approximations, or whole genome (GWAS) and polymorphisms associated with its pathogenesis.

Homocysteinylated protein levels in internal mammary artery (IMA) fragments and its genotype-dependence. S-homocysteine-induced methylation modifications in IMA and aortic fragments.

The resistance of internal mammary artery (IMA) toward atherosclerosis is not well understood. In plasma, homocysteine (Hcy) occurs in reduced, oxidized, homocysteine thiolactone and a component of proteins as a result of N- or S-homocysteinylation. We evaluated S/N-homocysteinylated protein levels in IMA fragments of patients undergoing coronary artery bypass grafting, and whether they were affected by genetic common variants.

Telmisartan-induced eNOS gene expression is partially independent of its PPAR-gamma agonist property.

Purpose: Telmisartan, an angiotensin II receptor blocker (ARB), also acts as an activator of peroxisome proliferator-activated receptor-gamma (PPAR-gamma; PPAR-γ). Several studies have explored the PPAR-γ-endothelial nitric oxide synthase (eNOS) pathway associated with improvement of endothelial function by telmisartan. The ability of telmisartan to induce gene expression and protein level of eNOS and PPARγ in adipocytes was investigated.

Replication of Relevant SNPs Associated with Cardiovascular Disease Susceptibility Obtained from GWAs in a Case-Control Study in a Canarian Population.

Recent genome-wide single nucleotide polymorphism (SNP) association studies (GWAS) have identified a number of SNPs that were significantly associated with coronary artery disease (CAD) and myocardial infarction (MI). We tested for replication of the previously described association with CAD in our case-control datasets of SNPs variants located at 1p13.1, 2q33.
