Building Muscle Doesn’t Require Lifting Heavy Weights, Study Shows

Current gym dogma holds that to build muscle size you need to lift heavy weights. However, a new study conducted at McMaster University has shown that a similar degree of muscle building can be achieved by using lighter weights. The secret is to pump iron until you reach muscle fatigue.

A Université de Montréal Research Team Is Developing A Pill Composed...

"Mice deprived of leptin will not stop eating. They become so big they have trouble moving around," says Moïse Bendayan, a pathology professor at the Université de Montréal Faculty of Medicine who has studied the leptin protein extensively.

Older Age Does Not Cause Testosterone Levels To Decline In Healthy...

A decline in testosterone levels as men grow older is likely the result -- not the cause -- of deteriorating general health, say...

Reducing Risk of “Long COVID” Death by 51% With Common Steroids

Evidence is growing that continued negative health impacts months after apparent recovery from severe Covid-19 are an important risk for some patients. For example,...

Skeleton Is An Endocrine Organ, Crucial To Regulating Energy Metabolism

Bones are typically thought of as calcified, inert structures, but researchers at Columbia University Medical Center have now identified a surprising and critically important novel function of the skeleton. They've shown for the first time that the skeleton is an endocrine organ that helps control our sugar metabolism and weight and, as such, is a major determinant of the development of type 2 diabetes.

At Last, A Reason Why Stress Causes DNA Damage

For years, researchers have published papers that associate chronic stress with chromosomal damage. Now researchers at Duke University Medical Center have discovered a mechanism that helps to explain the stress response in terms of DNA damage.

Blueberries May Inhibit Development Of Fat Cells

The benefits of blueberry consumption have been demonstrated in several nutrition studies, more specifically the cardio-protective benefits derived from their high polyphenol content. Blueberries have shown potential to have a positive effect on everything from aging to metabolic syndrome. Recently, a researcher from Texas Woman's University (TWU) in Denton, TX, examined whether blueberries could play a role in reducing one of the world's greatest health challenges: obesity.

Tai Chi Appears To Benefit Quality Of Life For Patients With...

Tai chi exercise appears to be associated with improved quality of life, mood and exercise self-efficacy in patients with chronic heart failure, according to a report in the April 25 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

New Stroke Therapy Successful in Rats: Protein Completely Restores Motor Function

People with impaired mobility after a stroke soon may have a therapy that restores limb function long after the injury, if a supplemental protein works as well in humans as it does. Two new studies by UC Irvine biologists have found that a protein naturally occurring in humans restores...

Magnetic Attraction Of Stem Cells Creates More Potent Treatment For Heart...

Researchers at the Cedars-Sinai Heart Institute have found in animals that infusing cardiac-derived stem cells with micro-size particles of iron and then using a magnet to guide those stem cells to the area of the heart damaged in a heart attack boosts the heart's retention of...

Insulin Resistance May Be Associated With Stroke Risk

Insulin resistance, a condition in which insulin produced by the body becomes less effective in reducing blood glucose levels, appears to be associated with an increased risk of stroke in individuals without diabetes, according to a report in the October issue of Archives of Neurology, one of the JAMA/Archives journals.

Depression Linked With Accumulation Of Visceral Fat

Numerous studies have shown that depression is associated with an increased risk of heart disease, but exactly how has never been clear. Now, researchers at Rush University Medical Center have shown that depression is linked with the accumulation of visceral fat, the kind of fat packed between internal organs at the waistline, which has...
