We have studied the ability of quercetin (a bioflavonoid) in tackling oxidative stress to alleviate the symptoms during ammonium chloride-induced hyperammonemia. Hyperammonemia was induced by the treatment of ammonium chloride (AC) 100 mg/kg b.w for 56 days. Hyperammonemic rats exhibited reduced urea (in plasma) and increased ammonia (in blood), uric acid (in plasma), creatinine (in serum), oxidative stress markers (thiobarbituric acid reactive substances (TBARS) and hydroperoxides (HP) and decreased levels of antioxidants (enzymatic and non-enzymatic) superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), reduced glutathione (GSH) in plasma and tissues (liver and brain) vitamins E and C (in plasma))...

Background: An elevated circulating cystathionine concentration, which arises in part from insufficiencies of vitamin B-6, B-12, or folate, has been shown to be associated with cardiovascular disease (CVD) risk. Hydrogen sulfide (H2S) is a gasotransmitter involved in vasodilation, neuromodulation, and inflammation. Most endogenously produced H2S is formed by pyridoxal phosphate (PLP)-dependent enzymes by noncanonical reactions of the transsulfuration pathway that yield H2S concurrently form lanthionine and homolanthionine...

The objective of this study was to compare the effects of ground corn or liquid molasses fed as the sole supplemental nonstructural carbohydrate (NSC) source on production performance, milk fatty acid (FA) profile, grazing behavior, and N metabolism in grazing dairy cows. A strip-grazing management system was used, with cows offered a new strip of fresh herbage after each milking, resulting in approximately 16 h of access to pasture daily. Animals were fed a diet formulated to yield an 86:14 forage-to-concentrate ratio consisting [dry matter (DM) basis] of 74% mixed grass-legume herbage, 12% mixed-mostly legume baleage, 12% NSC source, and 2% mineral-vitamin premix...

BACKGROUND AND AIMS: Apolipoproteins B (apoB) and A1 (apoA1) are major protein constituents of low-density and high-density lipoproteins, respectively, and serum concentrations of these apolipoproteins are associated with risk of atherosclerosis. Vitamin A (VA) has been implicated in lipoprotein metabolism. We evaluated the associations of serum apoB, apoA1 and their ratio (apoBAR) with risk of incident acute myocardial infarction (AMI) and the possible modification by serum VA. METHODS: Risk associations were assessed by Cox regression, and presented as hazard ratios (HRs) per standard deviation (SD) increment in log-transformed values of the lipid parameters, among 4117 patients with suspected stable angina pectoris, located in Western Norway...
