Among patients with advanced colon cancer receiving treatment that includes chemotherapy, a family history of colorectal cancer is associated with a significant reduction in cancer recurrence and death, with the risk reduced further by having an increasing number of affected first-degree relatives, according to a new study.

A higher-protein diet that emphasizes lean meats and low-fat dairy foods as sources of protein and calcium can mean weight loss without bone loss -- and the evidence is in bone scans taken throughout a new study.

New research provides evidence that a cure for Parkinson's disease could lie just inside the nose of patients themselves. Adult stem cells harvested from the noses of Parkinson's patients gave rise to dopamine-producing brain cells when transplanted into the brain of a rat.

Many healthy infants and toddlers may have low levels of vitamin D, and about one-third of those appear to have some evidence of reduced bone mineral content on X-rays, according to a new article.

Topical applications of a naturally occurring fat molecule have the potential to slow down skin aging, whether through natural causes or damage. Through both the normal aging process and external factors like UV damage, smooth, young skin inevitably becomes coarse and wrinkled. The basis of this wrinkling is that time and damage both lower the production of new collagen while increasing the levels of enzymes called MMPs that chew up existing collagen.

Exposure-based therapy, in which recent trauma survivors are instructed to relive the troubling event, may be effective in preventing the progression from acute stress disorder to post-traumatic stress disorder, according to a report in the June issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

A new study found that sugar-sweetened beverages (SSBs) are an increasingly large part of children and teens' diets. Teens who consume these SSBs drink an average of 356 calories per day, a significant increase from 10 years earlier.

People who are obese may be more likely to become depressed because they experience themselves as in poor health and are dissatisfied with their appearance.

New research into the toxins, virulence, spread and prevention of the superbug Clostridium difficile is reported in the Journal of Medical Microbiology. These findings will play a crucial role in providing us with ammunition in the fight against a sometimes deadly pathogen.

Researchers have genetically engineered a laboratory mouse in which pancreatic beta cells can regenerate after being induced to die. The new animal model's regenerative ability may provide future insights into improved treatments of diabetes, which affects millions of Americans.
