Washington, March 17: While moderate physical activity is known to be beneficial to health, researchers are now suggesting people to walk 150 minutes a week, which is equivalent to 30 minutes each day 5 times a week.
Researchers at the School of Exercise and Nutritional Sciences, San Diego State University, point out that pedometers widely used as a physical activity monitoring tool are unable to measure activity intensity.
They have determined that a rate of at least 100 steps per minute achieves moderate intensity activity.
London, Mar 17: A vegetarian diet could help protect against cancer, new research suggests.
Writing in the American Journal of Clinical Nutrition, researchers, who analyzed 52,700 men and women, found that those who did not eat meat had significantly fewer cancers overall than those who did.
However, surprisingly, scientists also found a higher rate of colorectal cancer - a disease linked with eating red meat
- among the vegetarians.
Washington, Mar 17: British researchers claim that hormone kisspeptin shows promise as a potential new treatment for infertility.
The study, led by Dr Waljit Dhillo from Imperial College London, has shown that giving kisspeptin to women with infertility can activate the release of sex hormones, which control the menstrual cycle.
According to researchers, the study could lead to a new fertility therapy for women with low sex hormone levels.
Washington. Mar 16: A new study has revealed that people who have lost cells in the hippocampus area of the brain are more likely to develop dementia.
For the study, researchers involved 64 people with Alzheimer''s disease, 44 people with mild cognitive impairment, which is the stage of memory problems that precedes Alzheimer''s disease, and 34 people with no memory or thinking problems.
They performed MRI scans on all of the participants at the beginning of the study and again an average of a year and a half later.
Washington, Mar 17: Researchers from Thomas Jefferson University have identified a novel signalling pathway that can be a potential target for heart failure therapy.
The pathway plays a significant role in the production of aldosterone, a hormone that promotes heart failure after a myocardial infarction.
Aldosterone production is mediated by a protein called beta-arrestin-1. Aldosterone is secreted by the adrenal cortex and its levels are elevated in chronic heart failure.
