More cheese, please! News study shows dairy is good for your metabolic health

More cheese, please! News study shows dairy is good for your metabolic health

Dairy is considered part of a healthy diet and dietary guidelines recommend the daily consumption of 2-4 portions of milk-based products such as milk, yogurt, cheese, cream and butter. It’s well known that dairy products contain calcium and minerals good for bones, but new research has shown that dairy consumption may also have beneficial effects on metabolic health and can reduce risk of metabolic diseases such as obesity and type 2 diabetes.

EEG study findings reveal how fear is processed in the brain

EEG study findings reveal how fear is processed in the brain

An estimated 8% of Americans will suffer from post traumatic stress disorder (PTSD) at some point during their lifetime. Brought on by an overwhelming or stressful event or events, PTSD is the result of altered chemistry and physiology of the brain Continue reading

Even small stressors may be harmful to men’s health, new research shows

Even small stressors may be harmful to men’s health, new research shows

Older men who lead high-stress lives, either from chronic everyday hassles or because of a series of significant life events, are likely to die earlier than the average for their peers, new research from Oregon State University shows. “We’re looking at long-term patterns of stress — if your stress level is chronically high, it could impact your mortality, or if you have a series of stressful life events, that could affect your mortality,” said Carolyn Aldwin, director of the Center for Healthy Aging Research in the College of Public Health and Human Sciences at OSU Continue reading

Biologists delay the aging process by ‘remote control’

Biologists delay the aging process by ‘remote control’

UCLA biologists have identified a gene that can slow the aging process throughout the entire body when activated remotely in key organ systems. Working with fruit flies, the life scientists activated a gene called AMPK that is a key energy sensor in cells; it gets activated when cellular energy levels are low Continue reading

Sex hormone levels in blood linked to risk of sudden cardiac arrest

Sex hormone levels in blood linked to risk of sudden cardiac arrest

Measuring the levels of sex hormones in patients’ blood may identify patients likely to suffer a sudden cardiac arrest, a heart rhythm disorder that is fatal in 95 percent of patients. A new study, published online by the peer-reviewed journal Heart Rhythm , shows that lower levels of testosterone, the predominant male sex hormone, were found in men who had a sudden cardiac arrest. Higher levels of estradiol, the major female sex hormone, were strongly associated with greater chances of having a sudden cardiac arrest in both men and women Continue reading

Taking a stand: Balancing the benefits, risks of physical activity in children

Taking a stand: Balancing the benefits, risks of physical activity in children

Today the Canadian Society of Exercise Physiology took a stand on the promotion of childhood physical activity and published their position and recommendations in the journal Applied Physiology, Nutrition, and Metabolism (APNM). This position stand provides an important overview of knowledge in the area of risk of physical activity for children and suggests both practical guidelines and a research agenda. Uniquely, this position stand addresses both benefits and risks of physical activity for children Continue reading

Taking pulse of aging of the brain

Taking pulse of aging of the brain

Researchers at the Beckman Institute at the University of Illinois at Urbana-Champaign have developed a new technique that can noninvasively image the pulse pressure and elasticity of the arteries of the brain, revealing correlations between arterial health and aging. Brain artery support, which makes up the cerebrovascular system, is crucial for healthy brain aging and preventing diseases like Alzheimer’s and other forms of dementia. Continue reading

Pigs’ hearts transplanted into baboon hosts remain viable more than a year

Pigs’ hearts transplanted into baboon hosts remain viable more than a year

Investigators from the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health (NIH) have successfully transplanted hearts from genetically engineered piglets into baboons’ abdomens and had the hearts survive for more than one year, twice as long as previously reported. This was achieved by using genetically engineered porcine donors and a more focused immunosuppression regimen in the baboon recipients, according to a study published in The Journal of Thoracic and Cardiovascular Surgery , an official publication of the American Association for Thoracic Surgery. Cardiac transplantation is the treatment of choice for end stage heart failure. Continue reading
