Pancreatic Cancer Prevented By Bitter Melon Juice In Mouse Models
Date: Mar-15-2013A University of Colorado Cancer study published this week in the journal Carcinogenesis shows that bitter melon juice restricts the ability of pancreatic cancer cells to metabolize glucose, thus cutting the cells' energy source and eventually killing them. "Three years ago researchers showed the effect of bitter melon extract on breast cancer cells only in a Petri dish. This study goes much, much farther. We used the juice - people especially in Asian countries are already consuming it in quantity...
New Targets Identified For Treating Osteoarthritis
Date: Mar-15-2013Few things in life are inevitable - death, taxes, and, if you live long enough, osteoarthritis. No treatment will stop or significantly slow the disease, and joint replacement is the only definitive treatment. That may change, however, as researchers such as Dr. Brendan Lee, professor of molecular and human genetics at Baylor College of Medicine, and his colleagues unravel the effects of a naturally occurring protein called lubricin or Proteoglycans 4 that appears to protect against the age as well as post-injury related changes...
Mechanism Discovered That Regulates Production Of Energy-Burning Brown Fat
Date: Mar-15-2013Joslin scientists have discovered a mechanism that regulates the production of brown fat, a type of fat which plays an important role in heat production and energy metabolism. The findings, which appear in the upcoming issue of Nature, may lead to new therapies that increase BAT formation to treat obesity. Two types of fat tissue are present in humans and other mammals: white adipose tissue (WAT) or white fat, which stores fat; and brown adipose tissue (BAT) or brown fat, which burns fat to produce heat...
Postpartum Depression Affects One In Seven New Moms
Date: Mar-15-2013In a surprising outcome, a high number of women - one in seven - suffers from postpartum depression (post-natal depression), according to the largest study of its kind to date published in JAMA Psychiatry. The findings also suggest that among mothers followed for a year after giving birth, close to 22 percent had been depressed. The authors recommend all pregnant women and new moms be screened for depression...
Interventions To Reduce Dietary Salt Supported By Canadians
Date: Mar-15-2013Many Canadians are concerned about dietary sodium and welcome government intervention to reduce sodium intake through a variety of measures, including lowering sodium in food, and education and awareness, according to a national survey. The top barriers to limiting sodium intake are a lack of lower sodium packaged and processed foods and lower sodium restaurant menu options. "Canadians are supportive of government intervention to lower salt intake," says lead investigator Mary R...
Micro-Endoscope - As Thin As A Human Hair
Date: Mar-15-2013Engineers at Stanford have demonstrated a high-resolution endoscope that is as thin as a human hair with a resolution four times better than previous devices of similar design. The so-called micro-endoscope is a significant step forward in high-resolution, minimally invasive bio-imaging with potential applications in research and clinical practice. Micro-endoscopy could enable new methods in diverse fields ranging from study of the brain to early cancer detection...
Avoiding Re-Hospitalization By Monitoring Activity In The Elderly Post-Discharge
Date: Mar-15-2013A new study has found a link between the activity levels of elderly people who have just been released from the hospital and the risk that they will require readmission within 30 days. The investigation draws on data collected from 111 patients aged 65 and older, each of whom was fitted with a "step activity monitor" during his or her hospital stay. Worn on the patient's ankle, the pager-sized device counted every step the person took during hospitalization and for a week after discharge...
More Frequent Testing For HIV Recommended
Date: Mar-15-2013Early HIV treatment can save lives as well as have profound prevention benefits. But those infected with the virus first must be identified before they can be helped. In a new study, two Northwestern University researchers report that current Centers for Disease Control and Prevention (CDC) HIV screening guidelines are too conservative and that more frequent testing would be cost-effective in the long run for both high- and low-risk groups. The Northwestern team performed a mathematical modeling study to assess "optimal testing frequencies" for HIV screening in different risk groups...
Top 20% Of Burnt-Out Employees Have A Dramatically Increased Risk Of Heart Disease
Date: Mar-15-2013Americans work longer hours, take fewer vacation days, and retire later than employees in other industrialized countries around the globe. With such demanding careers, it's no surprise that many experience job burnout - physical, cognitive, and emotional exhaustion that results from stress at work. Researchers have found that burnout is also associated with obesity, insomnia, and anxiety. Now Dr. Sharon Toker of Tel Aviv University's Faculty of Management and her fellow researchers - Profs...
Device May Lead To Quicker, More Efficient Diagnostics
Date: Mar-15-2013A twist on thin-film technology may provide a way to optically detect and analyze multiple substances simultaneously, leading to quicker diagnostics in such industries as health care and homeland security, according to Penn State researchers. One current optical-sensing technology can launch and guide a single light wave, called a surface-plasmon-polariton wave -- SPP wave -- that travels along the flat interface of the sample to be analyzed and a metal film. The SPP wave is launched by sending a light beam through a prism to the other face of the metal film...
