OBJECTIVE This study aimed to evaluate the effect of vitamin D3 megadose supplementation and influence of BsmI polymorphism in the VDR gene on the inflammatory profile and oxidative stress in elderly women with vitamin D deficiency. METHODS A double blind, randomized, placebo-controlled trial was conducted with 40 elderly women (aged 68±6 years) diagnosed(More)
The role of the Ntr system in Herbaspirillum seropedicae was determined via ntrB and ntrC mutants. Three phenotypes were identified in these mutants: Nif(-), deficiency in growth using nitrate, and low glutamine synthetase (GS) activity. All phenotypes were restored by the plasmid pKRT1 containing the intact glnA, ntrB and ntrC genes of H. seropedicae. The(More)
BACKGROUND Epidemiological studies have indicated a higher incidence of breast and gastric cancer in patients with nonsyndromic cleft lip with or without cleft palate (NSCL ± P) and their relatives, which can be based on similar genetic triggers segregated within family with NSCL ± P. METHODS This multicenter study evaluated the association of 9 single(More)
This study aimed to evaluate the relationship between the cardiometabolic profile, vitamin D status and BsmI polymorphism of the VDR gene in non-institutionalized elderly subjects. A cross-sectional study was conducted with a random and representative sample of 142 elderly subjects selected by cluster and recruited from a municipal assistance program.(More)
DNA methylation is mediated by DNA methyltransferases (DNMTs) that add a methyl group to the 5'-carbon of cytosine. The enzyme methylenetetrahydrofolate reductase (MTHFR) catalyzes the reduction of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate in the rate-limiting step of the cycle involving the methyl donor S-adenosyl-L-methionine (SAM). The(More)
