Triclosan, an antibacterial chemical widely used in hand soaps and other personal-care products, hinders muscle contractions at a cellular level, slows swimming in fish and reduces muscular strength in mice, according to researchers at the University of California, Davis, and the University of Colorado.

Eating cocoa flavanols daily may improve mild cognitive impairment, according to new research in the American Heart Association's journal Hypertension.

Newly published research led by Western's Dr. David Spence shows that eating egg yolks accelerates atherosclerosis in a manner similar to smoking cigarettes. Surveying more than 1200 patients, Spence found regular consumption of egg yolks is about two-thirds as bad as smoking when it comes to increased build-up of carotid plaque, a risk factor for stroke and heart attack. The research is published online in the journal Atherosclerosis.

Major depression or chronic stress can cause the loss of brain volume, a condition that contributes to both emotional and cognitive impairment. Now a team of researchers led by Yale scientists has discovered one reason why this occurs -- a single genetic switch that triggers loss of brain connections in humans and depression in animal models.

Tai Chi can be used as an effective form of exercise therapy for people with chronic obstructive pulmonary disease (COPD), according to new findings. The research, which was published online August 9, 2012 ahead of print in the European Respiratory Journal, suggests that this form of exercise can improve exercise capacity and quality of life in people with COPD and may be as beneficial as pulmonary rehabilitation.

Patients using cholesterol-lowering statin drugs may be at increased risk of developing age-related cataracts, according to a study -- "Age-related Cataract Is Associated with Type 2 Diabetes and Statin Use," in the August issue of Optometry and Vision Science, official journal of the American Academy of Optometry.

Corticosteroids, frequently prescribed to alleviate acute sinusitis, show no clinical benefit in treating the condition, according to a randomized controlled trial published in CMAJ (Canadian Medical Association Journal).

Men who do weight training regularly -- for example, for 30 minutes per day, five days per week -- may be able to reduce their risk of type 2 diabetes by up to 34%, according to a new study by Harvard School of Public Health (HSPH) and University of Southern Denmark researchers. And if they combine weight training and aerobic exercise, such as brisk walking or running, they may be able to reduce their risk even further -- up to 59%.

New research, to be published in the Journal of Clinical Psychiatry, finds that men who developed persistent sexual side effects while on finasteride (Propecia), a drug commonly used for male pattern hair loss, have a high prevalence of depressive symptoms and suicidal thoughts.

A picture tells a thousand words, so they say.
