The microbiome plays a major role in polyphenol metabolism, producing metabolites that are bioavailable and potentially more bioactive than the compounds from which they are derived. However, the microbiome can vary among individuals, and especially for those with co-morbidities, such as ulcerative colitis. In subjects with ulcerative colitis, the consequence of a 'dysbiotic' microbiome is characterized by decreased diversity of microbiota that may impact their capability to metabolize polyphenols into bioavailable metabolites.

However, the performance of qRT-PCR depends on the efficiency of virus concentration methods. In this study, the effect of Concanavalin A (Con A)-immobilized on polyacrylate beads (Con A-PAB) on the qRT-PCR performance, in terms of sensitivity and specificity to detect foodborne viruses in human fecal specimens was compared with commercial viral RNA extraction kit (VRNA).

Scope: Micronutrients are in small amounts in foods, act in concert, and require variable amounts of time to see changes in health and risk for disease. These first principles are incorporated into an intervention study designed to develop new experimental strategies for setting target recommendations for food bioactives for populations and individuals.
Methods And Results: A 6-week multivitamin/mineral intervention is conducted in 9-13 year olds.
Erythrosine B (ErB) is a cherry pink food colorant and is widely used in foods, drugs, and cosmetics. Quinoline yellow (QY) is a chinophthalon derivative used in cosmetic compositions for application to the skin, lips, and/or body surface. Previously, ErB and QY synthetic dyes were found to induce DNA damage in HepG2 cells.

The increasing production of silver nanoparticles (AgNPs) and titanium dioxide nanoparticles (TiONPs) has resulted in their elevated concentrations in the environment. This study was, therefore, aimed at determining the distribution, redox parameters, and genotoxic effects in male Wistar rats that were treated with either AgNP or TiONP individually, as well as under a co-exposure scenario. Animals were exposed via oral gavage to either sodium citrate buffer (vehicle), 0.

Some important environmental factors that influence the development of cardiovascular diseases (CVD) include tobacco, excess alcohol, and unhealthy diet. Methionine obtained from the diet participates in the synthesis of DNA, proteins, lipids and affects homocysteine levels, which is associated with the elevated risk for CVD development. Therefore, the aim of this study was to investigate the manner in which dietary methionine might affect cellular mechanisms underlying CVD occurrence.

Phomoxanthone A (PhoA) is a compound isolated from the endophytic fungus Phomopsis longicolla, associated with marine algae Bostrychia radicans. Although this metabolite was previously described regarding its high biological potential, there are no reports concerning the effects of this compound on DNA integrity. This study aimed to evaluate, in lymphocytes and promyelocytic leukemia HL60 cells, the cytotoxicity of this compound through MTT and neutral red (NR) assays, as well as its genotoxicity and mutagenicity by alkaline comet assay and cytokinesis-block micronucleus cytome assay (CBMN-Cyt), respectively.

Vitamin D3 deficiency affects 25-50% of the human population and has been associated with increased risk for development of hypertension. DNA damage induced by reactive oxygen species (ROS) occurs more often in hypertensive than in normotensive individuals, and vitamin D3 status can influence this relationship.

However, the molecular mechanisms underlying these neurological changes are not well understood. Thus, we aimed at evaluating which components of those neurotransmitter metabolism and signaling pathways can be modulated by maternal vitamin B6 -deficient or B6 -supplementated diets in the hippocampus of rat dams and their offspring.
