Cancer Patients Want Genetic Testing To Predict Metastasis Risk
If you had cancer and a genetic test could predict the risk of the tumor spreading aggressively, would you want to know - even if no treatments existed to help you?

Nonstick And Laser-safe Gold Aids Laser Trapping Of Biomolecules
Biophysicists long for an ideal material - something more structured and less sticky than a standard glass surface - to anchor and position individual biomolecules. Gold is an alluring possibility, with its simple chemistry and the ease with which it can be patterned. Unfortunately, gold also tends to be sticky and can be melted by lasers. Now, biophysicists at JILA have made gold more precious than ever - at least as a research tool - by creating nonstick gold surfaces and laser-safe gold nanoposts, a potential boon to laser trapping of biomolecules.

Phase III Study Showed Lucentis Improved Vision In Patients With Branch Retinal Vein Occlusion
Genentech, Inc. announced today that the Phase III study BRAVO showed Lucentis® (ranibizumab injection) improved vision, as measured by the primary endpoint of mean change from baseline in best-corrected visual acuity at six months, in patients with macular edema due to branch retinal vein occlusion. The safety profile of Lucentis was consistent with previous experience and no new adverse events related to Lucentis were observed in the study. Retinal vein occlusion (RVO) is a common cause of vision loss that occurs when blood flow through a retinal vein becomes blocked, such as by a blood clot.

Boost Your Mood At Least Half The Day With Physical Activity

The mood-enhancing effects of exercise are well documented, but a study presented at the American College of Sports Medicine"s 56th Annual Meeting in Seattle suggests the benefits may last much longer than previously thought. The study enrolled healthy men and women to complete a survey about their mood states at one-, two-, four-, eight-, 12- and 24-hour intervals following either exercise or rest. Although previous studies have found enhanced mood for up to an hour after exercise, this study found benefits for up to 12 hours following activity, compared to the resting group. "These positive effects on mood occurred in all types of participants, regardless of age, gender, or fitness level," said Jeremy Sibold, Ed.D., ATC, lead author. "In some cases, exercise may be able to complement other standard therapies as a cost-effective alternative in the treatment of mental health issues." Test subjects performed exercise at 60 percent of aerobic capacity, indicating that moderate-intensity exercise - like walking or light cycling - is enough to boost mood. Because the mood-enhancing effects of exercise fade after more than 12 hours post-exercise, Sibold says it"s important to make physical activity a daily habit. ACSM guidelines support the 2008 Physical Activity Guidelines for Americans, which recommend that adults participate in at least 150 minutes of moderate-intensity physical activity, which can be achieved in 30-minute segments five days a week.
