Vitamin E may delay decline in mild-to-moderate Alzheimer’s disease

Posted: 31 Dec 2013 01:37 PM PST

Vitamin E has just been shown to slow functional decline of Alzheimer's patients and reduce burdens on caregivers.

How emotions are mapped in the body

Posted: 31 Dec 2013 06:43 AM PST

Researchers found that the most common emotions trigger strong bodily sensations, and the bodily maps of these sensations were topographically different for different emotions. The sensation patterns were, however, consistent across different West European and East Asian cultures, highlighting that emotions and their corresponding bodily sensation patterns have a biological basis.

Most clinical studies on vitamins flawed by poor methodology

Posted: 30 Dec 2013 10:51 AM PST

Most large, clinical trials of vitamin supplements, including some that have concluded they are of no value or even harmful, have a flawed methodology that renders them largely useless in determining the real value of these micronutrients, a new analysis suggests. These flawed findings will persist until the approach to studying micronutrients is changed.

Toward molecular explanation for schizophrenia

Posted: 30 Dec 2013 10:50 AM PST

Schizophrenia was only recognized as a medical condition in the past few decades, and its exact causes remain unclear. Now a researcher has discovered that an important cell-maintenance process called autophagy is reduced in the brains of schizophrenic patients. The findings advance the understanding of schizophrenia and could enable the development of new diagnostic tests and drug treatments for the disease.

Potential new strategy to improve corneal transplant acceptance

Posted: 30 Dec 2013 10:49 AM PST

For the estimated 10 percent of patients whose bodies reject a corneal transplant, the odds of a second transplant succeeding are poor. All that could change, however, based on a study that has found a way to boost the corneal transplant acceptance rate.

Secret to fewer doctor office visits after 70: Play high school sports

Posted: 30 Dec 2013 07:15 AM PST

Seventy year olds who don't frequently visit the doctor have something unexpected in common -- most played high school sports. They were active on a team over 50 years ago and are more likely to be active into their late 70s.

Rheumatoid arthritis research shows potential of large-scale genetic studies for drug discovery

Posted: 26 Dec 2013 08:52 AM PST

The results of the largest international study to date into the genetic basis of rheumatoid arthritis have shed light on the biology of the disease and provide evidence that large-scale genetic studies can assist in the identification of new drugs for complex disorders such as rheumatoid arthritis.

Rock and rho: Proteins that help cancer cells groove

Posted: 26 Dec 2013 08:52 AM PST

Biologists have discovered that low oxygen conditions, which often persist inside tumors, are sufficient to initiate a molecular chain of events that transforms breast cancer cells from being rigid and stationery to mobile and invasive. Their evidence underlines the importance of hypoxia-inducible factors in promoting breast cancer metastasis.

Greater dietary fiber intake associated with lower risk of heart disease

Greater dietary fiber intake is associated with a lower risk of both cardiovascular disease and coronary heart disease.

Saving fertility not priority at most cancer centers, study shows

Posted: 19 Dec 2013 05:00 PM PST

Infertility is one of the most distressing long-term side effects of cancer treatment for adolescents and young adults. Yet the leading cancer centers -- which should be leaders in fertility preservation -- aren't doing an adequate job of helping patients protect their fertility. Most of these centers do not have policies to consistently identify which patients may be at risk for fertility loss, inform patients of this risk or refer them to fertility specialists.
