There are several hormones that impact how many ingested calories are stored as body fat. If any of these hormones are out of balance, a person can gain weight even though they may eat less food. One hormone that exerts a significant effect on hunger and fat storage is insulin.
Researchers orally fed the flavonoid apigenin to mice two weeks before implanting a prostate tumor, then continuing the feedings for eight weeks. In a second protocol, apigenin was fed to mice two weeks after tumor implantation. The first protocol mimicked prevention regimens, while the second followed therapeutic regimens for cancer.In both cases, the apigenin slowed tumor growth and did not appear to cause any adverse side effects.
The National Geographic looks at the prospects for enhancing human longevity through science in this article. The contents are mainstream and nothing new, but it's good to see the concepts of healthy life extension spreading in a somewhat more positive context than was prevalent a few years ago: "When asked about the most plausible methods for prolonging human life, Rose said, 'First drugs and then organs cultured using stem cells from your own tissues. It's just like cars are better now than t
WebMD takes a look at a recent study on the biochemistry of calorie restriction: "The results showed that mice that were fed 30% to 40% fewer calories produced more nitric oxide than those who followed an unrestricted diet. Calorie restriction also caused the mice to increase production of another chemical messenger that stimulated production of new mitochondria (the main energy source in cells) and increased oxygen consumption and expression of a protein previously shown to play a role in calo
Americans are eating themselves to death - soon poor diet and physical inactivity may overtake tobacco as the leading cause of death, according to a US government study.
About half of all deaths in the US can be attributed to preventable behaviours, shows the study by researchers at the Centers of Disease Control and Prevention in Atlanta, US, and led by Ali Mokdad.
A breakthrough in gene technology holds out the prospect of a more effective anti-ageing treatment.
It may also lead to new treatments to fight cancer.
Scientists from Newcastle University have found a way to enhance the body's natural repair mechanism.
NEW YORK (Reuters Health) - Men who gain weight rapidly between the ages of 25 and 40 are twice as likely to experience a recurrence of prostate cancer after surgery as men who keep the pounds off, research suggests. Men who are obese at age 40 and at the time of prostate cancer diagnosis also have a higher risk of recurrence.
Various U.S. and U.N. agencies and the Council on Foreign Relations are spreading the word that the Avian Influenza, if it breaks out this fall or winter, could be as severe as the worldwide Spanish Influenza epidemic of 1918, and they are predicting hundreds of millions of deaths worldwide. This influenza, currently isolated in China, is a hemorrhagic illness. It kills half of its victims by rapidly depleting ascorbate (vitamin C) stores in the body, inducing scurvy and collapse of the arterial
