Attention Baby Boomers: Get Screened for Hepatitis C Posted: 26 Apr 2013 06:11 PM PDT People born during 1945 through 1965 are five times more likely than other adults to be infected with hepatitis C. If you were born during these years, talk to your doctor about getting tested.

Physicists, biologists unite to expose how cancer spreads Posted: 26 Apr 2013 12:25 PM PDT A multi-institutional study has found that cancer cells that can break out of a tumor and invade other organs are more aggressive and nimble than nonmalignant cells.

New drug stimulates immune system to kill infected cells in animal model of hepatitis B infection Posted: 26 Apr 2013 12:25 PM PDT A novel drug developed and tested in an animal model suppresses hepatitis B virus infection by stimulating the immune system and inducing loss of infected cells.

Challenges faced by adolescent and young adult cancer survivors Posted: 26 Apr 2013 12:25 PM PDT New research focuses on the difficulties of transitioning to adulthood while dealing with the long-term and late effects of cancer and its treatment.

Hitting 'reset' in protein synthesis restores myelination: Suggests new treatment for misfolded protein diseases such as Alzheimer's Posted: 26 Apr 2013 10:50 AM PDT Neuroscientists show how turning down synthesis of a protein improves nerve, muscle function in a common neuropathy. A potential new treatment strategy for patients with Charcot-Marie-Tooth disease is on the horizon. This research may also have relevance for other diseases that result from misfolded proteins, including Alzheimer's disease, Parkinson's, multiple sclerosis, Type 1 diabetes, cancer and mad cow disease.

Battery of tests on cancer cells shows them as 'squishy,' yet tactically strong Posted: 26 Apr 2013 10:50 AM PDT A team of student researchers and their professors from 20 laboratories around the country have gotten a new view of cancer cells. The work could shed light on the transforming physical properties of these cells as they metastasize.

Guide on new oral anticoagulant drugs Posted: 26 Apr 2013 10:48 AM PDT A practical guide on the use of the new oral anticoagulants (NOACs) has been produced. A guide was needed to summarize existing information on different drugs, to answer clinical questions that fall outside what drug companies can legally answer, and to make distinctions between the different drugs.

Weight loss programs via virtual reality Posted: 26 Apr 2013 08:56 AM PDT There are many barriers that can interfere with weight loss. For those attending face-to-face weight loss programs, barriers can include travel, conflict with work and home, need for childcare, and loss of anonymity. In a new study investigators continue to explore alternative weight management delivery methods to eliminate some of these barriers. The solution they are investigating -- virtual reality for weight loss and weight maintenance.

National survey highlights perceived importance of dietary protein to prevent weight gain Posted: 26 Apr 2013 08:56 AM PDT Atkins Diet, Zone Diet, South Beach Diet, etc., etc., etc. Chances are you have known someone who has tried a high protein diet. In a new study, researchers found a relatively high proportion of women who reported using the practice of "eating more protein" to prevent weight gain, which was associated with reported weight loss.

Using mobile phone apps in weight-loss programs Posted: 26 Apr 2013 08:55 AM PDT Mobile phones using text messaging and monitoring have been shown to be useful additions to health programs.

Intermittent fasting may help those with diabetes and cardiovascular disease, study suggests Posted: 26 Apr 2013 08:54 AM PDT Intermittent fasting is all the rage, but scientific evidence showing how such regimes affect human health is not always clear cut. Now a scientific review suggests that fasting diets may help those with diabetes and cardiovascular disease, alongside established weight loss claims.

Protein shaped like a spider: Immune protein C4BP is potentially suitable as a transporter for drugs Posted: 26 Apr 2013 08:54 AM PDT The protein C4BP is similar to a spider in its spatial form with eight "arms." This leads the scientists to unconventional ideas -- the protein is possibly suitable as a scaffold for the transport of active pharmaceutical substances, particularly biomolecules.

Flu and bacteria: Better prognosis for this potentially fatal combination Posted: 26 Apr 2013 08:54 AM PDT Scientists have provided insights into how much harm bacteria can cause to the lung of people having the flu. The results could prompt the development of alternative treatments for flu-related bacterial infections, to improve patient outcome and prevent permanent lung damage.

Scientists discover new way protein degradation is regulated Posted: 26 Apr 2013 08:46 AM PDT Researchers have identified the mechanism by which the cell's proteasome ramps up its activity to take care of unwanted and potentially toxic proteins. The finding has implications for treating muscle wasting and neurodegeneration, and suggests that small molecule inhibitors of this mechanism may be clinically useful in treating multiple myeloma.

U.S. health insurance survey: 84 million people were uninsured for a time or underinsured in 2012 Posted: 26 Apr 2013 04:38 AM PDT 84 million people -- nearly half of working-age US adults -- went without health insurance for a time last year or had out-of-pocket costs that were so high relative to income they were considered underinsured.

Cardio could hold key to cancer cure Posted: 26 Apr 2013 04:38 AM PDT Regular exercise has been proven to reduce the chance of developing liver cancer in a world-first mice study that carries hope for patients at risk from hepatocellular carcinoma.

Researchers 'capture' replication of human genome for first time Posted: 25 Apr 2013 10:28 AM PDT Scientists have for the first time obtained a panoramic photo of the proteins that take part in human DNA division, a process known as replication.

Suppressing protein may stem Alzheimer's disease process Posted: 25 Apr 2013 10:26 AM PDT Scientists have discovered a potential strategy for developing treatments to stem the disease process in Alzheimer's disease. It's based on unclogging removal of toxic debris that accumulates in patients' brains, by blocking activity of a little-known regulator protein called CD33. Too much CD33 activity may promote late-onset Alzheimer's by preventing support cells from clearing out toxic plaques. Future medications that impede CD33 activity might help prevent or treat the disorder.

Potential diabetes breakthrough: Hormone spurs beta cell production Posted: 25 Apr 2013 10:26 AM PDT Researchers have discovered a new hormone that holds promise for a dramatically more effective treatment of type 2 diabetes, a metabolic illness afflicting an estimated 26 million Americans. The researchers believe the hormone might also have a role in treating type 1, or juvenile, diabetes.

Gene networks in brains of deceased patients reveal potential therapy for Alzheimer's disease Posted: 25 Apr 2013 10:26 AM PDT Most information about the cause of Alzheimer's is based on studies from animal models. Now, a study examines the brain tissue of deceased human patients and sheds light on dysfunctions in molecular networks in the brain that are at the root of Alzheimer's. By showing that the TYROBP gene plays a key role in disrupting immune system pathways in the brains of Alzheimer's patients, the study reveals a potential therapeutic target for preventing brain damage.

Psychological vulnerable older adults are more susceptible to fraud Posted: 25 Apr 2013 10:24 AM PDT Financial exploitation, particularly thefts and scams, are increasing at an alarming rate, particularly in older adults. This study examined this population and their vulnerability for experiencing fraud.

Reviving a foe of cancer Posted: 25 Apr 2013 10:23 AM PDT Cancer cells are a problem for the body because they multiply recklessly, refuse to die and blithely metastasize to set up shop in places where they don't belong. One protein that keeps healthy cells from behaving this way is a tumor suppressor named p53. This protein stops potentially precancerous cells from dividing and induces suicide in those that are damaged beyond repair. Not surprisingly, p53's critical function is disrupted in most cancers.

Sexually explicit material affects behavior in young people less than thought Posted: 25 Apr 2013 06:15 AM PDT Viewing sexually explicit material through media such as the Internet, videos, and magazines may be directly linked with the sexual behavior of adolescents and young adults, but only to a very small extent. The findings suggest that the practice is just one of many factors that may influence the sexual behaviors of young people.

Influence of the family on back pain sufferers Posted: 25 Apr 2013 06:13 AM PDT Researchers have published a research paper that focuses on the social factors involved in back pain sufferers returning to work, to give a wider context to the medical factors that are often considered.
