Metabolism is the sum of chemical changes involved in the function of nutrition. There are two phases: anabolism (constructive or assimilative changes) and catabolism (destructive or retrograde changes).
Longer measured sleep is associated with lower calcification incidence independent of examined potential mediators and confounders. – Participants in a study who slept on average an hour longer per night than other participants had an associated lower incidence of coronary artery calcification, which is thought to be a predictor of future heart disease, according to a study in the December 24/31 issue of JAMA.
Breathing life into injured lungs: World-first technique will expand lung donor organ pool – For the first time in the world, transplant surgeons at Toronto General Hospital, University Health Network used a new technique to repair an injured donor lung that was unsuitable for transplant, and then successfully transplanted it into a patient.
Sleep disordered breathing severity is associated with REE – Resting Energy Expenditure. – Individuals with sleep-related breathing disorders appear to burn more calories when resting as their conditions become more severe, according to a report in the December issue of Archives of Otolaryngology?Head & Neck Surgery, one of the JAMA/Archives journals.
New research suggests that genes that predispose people to obesity act in the brain and that perhaps some people are simply hardwired to overeat. – A genetic study of more than 90,000 people has identified six new genetic variants that are associated with increased Body Mass Index (BMI), the most commonly used measure of obesity. Five of the genes are known to be active in the brain, suggesting that many genetic variants implicated in obesity might affect behaviour, rather than the chemical processes of energy or fat metabolism.
High-dose vitamin B supplementation for patients with mild to moderate Alzheimer disease did not slow the rate of cognitive decline. – A clinical trial led by Paul S. Aisen, M.D., professor of neurosciences at the University of California, San Diego School of Medicine, showed that high-dose vitamin B supplements did not slow the rate of cognitive decline in patients with mild to moderate Alzheimer disease.
University of Wisconsin-Madison Research team discovers brain pathway responsible for obesity. – University of Wisconsin-Madison researchers, for the first time, have found a messaging system in the brain that directly affects food intake and body weight.
A new testing device may give doctors early warning of eye disease, especially vision trouble linked to diabetes. – A new vision screening device, already shown to give an early warning of eye disease, could give doctors and patients a head start on treating diabetes and its vision complications, a new study shows.
Scientists have found that the compound resveratrol slows age-related deterioration and functional decline, but does not increase longevity. – Large doses of a red wine ingredient can ward off many of the vagaries of aging in mice who begin taking it at midlife, according to a new report published online on July 3rd in Cell Metabolism, a Cell Press publication. Those health improvements of the chemical known as resveratrol-including cardiovascular benefits, greater motor coordination, reduced cataracts and better bone density-come without necessarily extending the animals’ lifespan.
Weight loss bariatric surgery for morbid obesity also prevents cancer, revealed by McGill/MUHC researchers. – The latest study by Dr. Nicolas Christou of the McGill University Health Centre (MUHC) and McGill University shows that Weight loss bariatric surgery decreases the risk of developing cancer by up to 80 percent.
Breakfast really could be the most important meal of the day when it comes to losing weight. Healthy breakfast everyday and the bigger the bowl, the better the result. – Researchers revealed a possible way to overcome the common problem of dieters eventually abandoning their diet and regaining the weight they lost. Eat a big breakfast packed with carbohydrates (“carbs”) and protein, then follow a low-carb, low-calorie diet the rest of the day.
New genetic variants found that influence fat mass, weight and risk of obesity, revealed by UK reasearchers. – A study of 90,000 people has uncovered new genetic variants that influence fat mass, weight and risk of obesity. The variants act in addition to the recently described variants of the FTO gene: on average, adults carrying variants in both genes are 3.8 kg (or 8.5 lb) heavier.
Scientists have discovered a way to aid weight loss and reduce the likelihood of developing diabetes by manipulating fat cells to increase the body?s metabolism. – Scientists from Melbourne’s Howard Florey Institute have discovered a way to aid weight loss and reduce the likelihood of developing diabetes by manipulating fat cells to increase the body’s metabolism. As well as metabolising fat, fat cells help regulate blood pressure and blood volume through the renin-angiotensin system.
