Discrimination gut check

AIM: There are growing evidences linking chronic apical periodontitis (CAP) to atherosclerosis. Gut microbiota is found to be involved in the development of atherosclerosis. Recent studies have shown that CAP could change the diversity and composition of the gut microbiota. It was therefore, we hypothesized that gut microbiota and its metabolites could mediate the impact of CAP on atherosclerosis. METHODOLOGY: Twenty-four 5-week-old lipoprotein E knockout (apoE-/- ) mice were randomly divided into four groups: the CAP group, Con group, Co-CAP (cohoused with CAP), and Co-Con (cohoused with Con) group...

Objectives: Red meat consumption can promote atherosclerosis since the gut microbiota can metabolize L-carnitine from meat into trimethylamine N-oxide (TMAO) which is a causative risk for cardiovascular disease. Garlic has long been associated with health benefits. Allicin is a major bioactive compound typically found in blend fresh garlic. It possesses the antibacterial, anti-oxidant, and cholesterol-lowering effects. The aim of this study is to investigate the effect allicin on the gut microbiota and its metabolites on cardiovascular disease by using the long-term carnitine treatment ApoE (-/-) mice model...

AIM: Chronic stress increases disease vulnerability factors including inflammation, a pathological characteristic potentially regulated by the gut microbiota. We checked the association between the gut microbiome and psychosocial stress in children/adolescents and investigated which stress parameter (negative versus positive emotion, self-report versus parental report, events versus emotions, biomarker cortisol versus parasympathetic activity) is the most relevant indicator herein. METHODS: Gut microbiome sequencing was completed in fecal samples from 93 Belgian 8-16y olds...

The nutrient intakes of mammalian herbivores depend on the amount and the nutrient content of the plant species and plant parts which they eat. We review the merits of oesophageal-fistulated (OF) animals, microhistological procedures, stable C-isotope discrimination and plant cuticular-wax markers as methods for estimating diet composition and intake in both ruminant and non-ruminant herbivores. We also briefly discuss methods based on grazing behaviour measurements or on H2O or Na turnover, and methods for estimating supplement or soil intake...
