Consumer attitudes and understanding of low sodium claims on food: An analysis of healthy and hypertensive individuals

submitted by: Christina.L.Wong
Background: Sodium-related claims on food labels should facilitate lower-sodium food choices; however, consumer attitudes and understanding of such claims are unknown. Objectives: We evaluated consumer attitudes and understanding of different types of sodium claims and the effect of having hypertension on responses to such claims. Design: Canadian consumers (n = 506), with and without hypertension, completed an online survey that contained a randomized mock package experiment, which...

Grape Powder Supplementation Prevents Oxidative Stress–Induced Anxiety-Like Behavior, Memory Impairment, and High Blood Pressure in Rats

submitted by: ssalim
We examined whether or not grape powder treatment ameliorates oxidative stress–induced anxiety-like behavior, memory impairment, and hypertension in rats. Oxidative stress in Sprague-Dawley rats was produced by using L-buthionine- (S,R)-sulfoximine (BSO). Four groups of rats were used: 1) control (C; injected with vehicle and provided with tap water), 2) grape powder–treated (GP; injected with vehicle and provided for 3 wk with 15 g/L grape powder dissolved in tap water), 3)...

Low folate status enhances pregnancy changes in plasma betaine and dimethylglycine concentrations and the association between betaine and homocysteine

submitted by: Michelle Murphy
ABSTRACT Background: Folate, choline, and betaine participate in homocysteine metabolism. It is not known whether they interact during pregnancy. Objective: The objective was to investigate how folate status affects choline, betaine, and dimethylglycine during pregnancy. Design: Fasting plasma folate, cobalamin, free choline, betaine, dimethylglycine, and total homocysteine (tHcy) were measured longitudinally at ,12, 15, 24–27, and 34 gestational weeks (GW); at labor (nonfasting);...

Functional reconstitution of NKT cells in HIV-1 infected individuals

submitted by: dzhoumda
A reduction in the generation of lung-homing TB-specific effector memory CD4 Th1 cells after HIV infection is a key factor in the increased risk of active TB disease. Natural killer T cells are an innate type of immune cells responsible for first line of anti-viral defense, which may “jump-start” the adaptive immune responses and regulate the Th1 versus Th2 differentiation of CD4 helper T cells, through their unique ability to activate antigen-presenting cells (e.g., DCs). The regulatory...
