Moderate physical activity is associated with a greater than 50 percent reduction in cardiovascular death in over-65s, according to research presented at ESC Congress 2016 today. The 12-year study in nearly 2,500 adults aged 65 to 74 years found that moderate physical activity reduced the risk of an acute cardiovascular event by more than 30 percent. High levels of physical activity led to greater risk reductions.
A novel activity tracker has been developed that uses heart rate data to personalize the amount of exercise needed to reduce the risk of death from cardiovascular disease. The science behind the tracker is presented for the first time today at ESC Congress 2016.
A study evaluated the influence of nitrogen fertility levels on biomass and concentrations of nutritionally important carotenoid and chlorophyll pigments in purslane. Two purslane cultivars were grown in nutrient solution culture under four nitrogen concentrations. Results showed no influence of nitrogen treatment concentration on purslane shoot tissue fresh weight accumulation. Nitrogen treatment significantly influenced purslane shoot tissue beta-carotene, lutein, neoxanthin, total carotenoids, chlorophyll a, chlorophyll b, total chlorophyll, and the chlorophyll a to b ratio.
For those who need to lose weight, taking off a few pounds by dieting, exercising or both is powerful protection against cardiovascular disease.
Simple changes in how we cook could go a long way towards preventing diabetes, say researchers at the Icahn School of Medicine at Mount Sinai.
Nutritional stress is a normal part of life; going hungry on a short-term basis generally does not impair important functions. The brain coordinates the response to nutritional stress but how it does this was, until now, not well understood. Researchers from the National Centre for Biological Sciences, Bangalore, have discovered a brain circuit that allows fruit flies to take a major developmental step in their lives despite nutritional stress.
Scientists have found that fish oil supplements can reverse the effects of a high fat diet according to a study published in The Journal of Physiology.
Too much manganese early in development causes lasting attention deficits and other impairments in rats. Studies of children and adolescents have associated excess manganese in the diet with attention deficits, but confounding factors in those studies have made it impossible to show a cause and effect relationship. The new study is the first to establish a causal link between exposure to elevated manganese in the diet and attentional dysfunction in an animal model.
Multivariate analysis of cognitive tests in Alzheimer's disease identifies five distinct groups of Alzheimer's disease patients, and suggests that multivitamins might slow progression only in certain groups.
A landmark study, set to publish tomorrow in the American Journal of Public Health, has found that standing desks lower the BMI trajectory in elementary-aged children over a two-year span--by an average of 5.24 percentile points.
