Infection With Roundworm Quells Obesity And Related Metabolic Disorders
Date: Apr-29-2013Researchers at the University of Maryland School of Medicine, Baltimore, have shown in a mouse model that infection with nematodes (also known as roundworms) can not only combat obesity but ameliorate related metabolic disorders. Their research is published ahead of print online in the journal Infection and Immunity. Gastrointestinal nematodes infect approximately 2 billion people worldwide, and some researchers believe up until the 20th century almost everyone had worms...
Connection Between Chemoresponse Assays And Improved Ovarian Cancer Survival Rates
Date: Apr-29-2013This spring, a team of researchers has released results from an eight-year study that shows improved survival rates for women diagnosed with ovarian cancer who undergo cancer tumor testing to determine the best treatment. Part of the team was Richard G. Moore, MD, director of the Center for Biomarkers and Emerging Technologies and a gynecologic oncologist with the Program in Women's Oncology at Women & Infants Hospital of Rhode Island...
Non-Alcoholic Fatty Liver Disease Increases Risk Of Early Atherosclerotic Lesions
Date: Apr-29-2013A study presented at the International Liver CongressTM 2013 - which evaluated the relationship between non-alcoholic fatty liver disease (NAFLD), early predictors of atherosclerosis and the 10-year Framingham risk score (FRS) - showed that NAFLD increases the risk of early atherosclerotic lesions independent of established cardiovascular (CV) risk factors. NAFLD is one of the most common causes of chronic liver disease. Patients with NAFLD have an excess prevalence of CV events and typically have an increase frequency of risk factors already known to be directly related to atherosclerosis...
Nanoparticles In Action
Date: Apr-29-2013The macroscopic effects of certain nanoparticles on human health have long been clear to the naked eye. What scientists have lacked is the ability to see the detailed movements of individual particles that give rise to those effects. In a recently published study, scientists at the Virginia Tech Carilion Research Institute invented a technique for imaging nanoparticle dynamics with atomic resolution as these dynamics occur in a liquid environment. The results will allow, for the first time, the imaging of nanoscale processes, such as the engulfment of nanoparticles into cells...
Cellular Secrets May Be Revealed By New Imaging Technology
Date: Apr-29-2013Researchers have married two biological imaging technologies, creating a new way to learn how good cells go bad. "Let's say you have a large population of cells," said Corey Neu, an assistant professor in Purdue University's Weldon School of Biomedical Engineering. "Just one of them might metastasize or proliferate, forming a cancerous tumor. We need to understand what it is that gives rise to that one bad cell...
Vitamin D Therapy Could Be A Powerful Weapon In The Fight Against Liver Fibrosis
Date: Apr-29-2013Liver fibrosis results from an excessive accumulation of tough, fibrous scar tissue and occurs in most types of chronic liver diseases. In industrialized countries, the main causes of liver injury leading to fibrosis include chronic hepatitis virus infection, excess alcohol consumption and, increasingly, nonalcoholic steatohepatitis (NASH)...
Anxiety And Stress Benefits From Exercise, Even When Forced
Date: Apr-29-2013Being forced to exercise may still help reduce anxiety and depression just as exercising voluntarily does, according to a new study by researchers at the University of Colorado Boulder. Past studies have shown that people who exercise are more protected against stress-related disorders. And scientists know that the perception of control can benefit a person's mental health. But it has been an open question whether a person who feels forced to exercise, eliminating the perception of control, would still reap the anxiety-fighting benefits of the exercise...
Potential New Way To Detect Colorectal And Other Cancers
Date: Apr-29-2013A unique new study led by University of Kentucky Markey Cancer Center researchers Guo-Min Li and Libya Gu, in collaboration with Dr. Wei Yang at National Institutes of Health, reveals a novel mechanism explaining the previously unknown root cause of some forms of colorectal cancers. The study, published in Cell, discovers that an abnormal histone protein modification impairs a DNA repair machinery that controls cancer development, yielding a potential new way of detecting these types of colorectal cancers...
Hormone Levels And Sexual Motivation Among Young Women
Date: Apr-29-2013Feeling frisky? If so, chances are greater your estrogen level - and, perhaps, fertility - are hitting their monthly peak. If not, you're more likely experiencing a profusion of desire-deadening progesterone, and the less fertile time in your cycle. Oh, the power of hormones. Researchers have long suspected a correlation between hormone levels and libido, but now scientists at UC Santa Barbara, led by James Roney, a professor in the Department of Psychological and Brain Sciences, have actually demonstrated hormonal predictors for sexual desire...
Putting A Price On Life-Saving Helicopter Transport Of Trauma Victims
Date: Apr-29-2013Researchers at the Stanford University School of Medicine have for the first time determined how often emergency medical helicopters need to help save the lives of seriously injured people to be considered cost-effective compared with ground ambulances. The researchers found that if an additional 1.6 percent of seriously injured patients survive after being transported by helicopter from the scene of injury to a level-1 or level-2 trauma center, then such transport should be considered cost-effective...
