A systematic review of research into the use of nutritional supplements for the treatment of anxiety disorders has found strong evidence for the use of extracts of passionflower or kava and combinations of L-lysine and L-arginine.

Fish oil -- long encouraged by doctors as a supplement to support heart and joint health, among other benefits -- induced severe colitis and colon cancer in mice in research led by Michigan State University and published this month in the journal Cancer Research.

The most toxic free radical appears responsible for much of the lung damage that can result from oxygen therapy in the critically ill or injured, Medical College of Georgia researchers report. Within just a few days, ventilators and oxygen chambers used to significantly increase oxygen levels can also dramatically increase levels of peroxynitrite, an oxidant powerful enough to break down DNA and cause proteins to malfunction, said Dr. Yunchao Su, pharmacologist in the MCG Schools of Medicine and Graduate Studies.

A new research study published in The FASEB Journal may change how sports injuries involving muscle tissue are treated, as well as how much patient monitoring is necessary when potent anti-inflammatory drugs are prescribed for a long time. That's because the study shows for the first time that inflammation actually helps to heal damaged muscle tissue, turning conventional wisdom on its head that inflammation must be largely controlled to encourage healing.

When mice are given drinking water laced with a special concoction of amino acids, they live longer than your average mouse, according to a new report in the October issue of Cell Metabolism, a Cell Press publication. The key ingredients in the supplemental mixture are so-called branched-chain amino acids, which account for 3 of the 20 amino acids (specifically leucine, isoleucine, and valine) that are the building blocks of proteins.

Wrist fractures have an important personal and public health impact and may play a role in the development of disability in older people, according to a new study published online in the British Medical Journal.

An elderly person's risk of falling is too often overlooked when trying to prevent them from getting serious fractures, for instance of the hip or wrist, according to an article published in the British Medical Journal.

Home-based exercises followed by voluntary home training seem to be associated with long-term effects on balance and gait (manner of walking), and may help protect high-risk, elderly women from hip fractures, according to a report in the September 27 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Ragweed allergy season can be even more miserable for those with dog, cat or dust mite allergies, according to new research. These year-round allergies appear to "pre-prime" the immune system so symptoms hit harder, according to a study recently published in the Annals of Allergy, Asthma & Immunology, the scientific journal of the American College of Allergy, Asthma and Immunology (ACAAI).
