| Biomarker predicts risk of breast cancer recurrence after tamoxifen treatment Posted: 29 Jun 2013 01:47 PM PDT A biomarker reflecting expression levels of two genes in tumor tissue may be able to predict which women treated for estrogen-receptor-positive breast cancer should receive a second estrogen-blocking medication after completing tamoxifen treatment.  |
| Getting a good night's sleep is a nightmare for many Americans Posted: 29 Jun 2013 01:46 PM PDT Summer means more hours of daylight and for many, it contributes to trouble falling asleep. More than 40 million Americans suffer from chronic sleep disorders, resulting in $18 billion in cost to employers due to sleep loss issues.  |
| 'First bionic eye' retinal chip for blind Posted: 29 Jun 2013 01:46 PM PDT A new bionic eye works by converting video images captured by a miniature camera, housed in the patient's glasses, into a series of small electrical pulses that are transmitted wirelessly to an array of electrodes on the surface of the retina. These pulses are intended to stimulate the retina's remaining cells resulting in the corresponding perception of patterns of light in the brain. Patients then learn to interpret these visual patterns thereby regaining some visual function.  |
| Eating right, exercise may help prostate cancer patients reduce risk of aggressive tumors Posted: 29 Jun 2013 01:46 PM PDT A new study finds that following well-known cancer-prevention recommendations may also benefit those already diagnosed with the disease.  |
| Late bedtimes and less sleep may lead to weight gain in healthy adults Posted: 28 Jun 2013 01:08 PM PDT A new study suggests that healthy adults with late bedtimes and chronic sleep restriction may be more susceptible to weight gain due to the increased consumption of calories during late-night hours.  |
| Pre-existing insomnia linked to PTSD and other mental disorders after military deployment Posted: 28 Jun 2013 01:08 PM PDT New research found military service members who have trouble sleeping prior to deployments may be at greater risk of developing post-traumatic stress disorder (PTSD), depression and anxiety once they return home. The study found that pre-existing insomnia symptoms conferred almost as a large of a risk for those mental disorders as combat exposure.  |
| Study links gene to lymphatic abnormalities Posted: 28 Jun 2013 06:17 AM PDT The often forgotten lymphatic circulatory system may be intimately involved in vascular disorders, according to a study by researchers.  |
