In Pathological Gambling, Problems Differ With Age
Date: Mar-18-2013To successfully treat pathological gambling, you need to intervene at an early stage, according to Susana Jimenez-Murcia from the University Hospital of Bellvitge in Spain and colleagues. Their study shows that a patient's age influences how severe the psychopathology and clinical aspects of pathological gambling are. Their work is published online in Springer's Journal of Gambling Studies. These days, access to 24-hour, uncontrolled gambling is straightforward thanks largely to the internet...
Key Step In The Manufacture Of Red Blood Cells Decoded
Date: Mar-18-2013A healthy adult must generate as many as one hundred billion new red blood cells each day, to maintain the numbers circulating in his blood. A team of EPFL researchers has identified a key step in the process by which red blood cells are born. The discovery could not only shed light on the causes of blood disorders such as anaemia, it could also bring closer the medics' dream of being able to manufacture red blood cells in the lab - thus providing a potentially inexhaustible supply of an essential component of blood for transfusion...
Enlisting Two Suboptimal Vaccine Approaches Could Lead To A Universal Shot Against The Flu
Date: Mar-18-2013Seasonal epidemics of influenza result in nearly 36,000 deaths annually in the United States, according to the Centers for Disease Control. Current vaccines against the influenza virus elicit an antibody response specific for proteins on the outside of the virus, specifically the hemagglutinin (HA) protein. Yearly vaccines are made by growing the flu virus in eggs. The viral envelope proteins, including HA, are cleaved off and used as the vaccine, but vary from year to year, depending on what flu strains are prevalent...
Promising New Cancer Diagnostic Technique
Date: Mar-18-2013Cancer cells break down sugars and produce the metabolic acid lactate at a much higher rate than normal cells. This phenomenon provides a telltale sign that cancer is present, via diagnostics such as PET scans, and possibly offers an avenue for novel cancer therapies. Now a team of Chilean researchers at The Centro de Estudios CientÃficos (CECs), with the collaboration of Carnegie's Wolf Frommer, has devised a molecular sensor that can detect levels of lactate in individual cells in real time...
Herpes Simplex Virus Vector Offers Novel Treatment Approach For Bladder Pain
Date: Mar-18-2013Severe chronic pain associated with conditions such as bladder pain syndrome/interstitial cystitis often require the use of opioid medication, with the risk of dependency and serious adverse reactions. An alternative treatment strategy increases the levels of a naturally occurring painkiller in and around the nerves that deliver pain signals to the bladder. This new therapeutic approach is described in an article in Human Gene Therapy, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available on the Human Gene Therapy website...
Terahertz Pulses That Destroy Skin Tissue, Increase Tumor-Suppressing Proteins At The Same Time
Date: Mar-18-2013Terahertz (THz) radiation, a slice of the electromagnetic spectrum that occupies the middle ground between microwaves and infrared light, is rapidly finding important uses in medical diagnostics, security, and scientific research. As scientists and engineers find evermore practical uses for this form of radiation, questions persist about its potential human health risks. New research performed on lab-grown human skin suggests that short but powerful bursts of THz radiation may both cause DNA damage and increase the production of proteins that help the body fight cancer...
Breast Cancer Patients Should Avoid High-Fat Dairy Products
Date: Mar-18-2013Patients who have suffered from breast cancer should avoid consuming high-fat dairy products in order to improve their long-term survival. The study, carried out by Kaiser Permanente researchers and published in the Journal of the National Cancer Institute, is one of the first of its kind to identify a link between high fat dairy consumption and poorer breast cancer survival. Other studies have found associations between certain eating habits and breast cancer risk...
Marijuana Use May Raise Nicotine Dependence
Date: Mar-18-2013People who have used marijuana may be more susceptible to the addictive properties of nicotine, researchers from the National Institute on Drug Abuse reported in the journal Neuropsychopharmacology. More specifically, it is the consumption of the main psychoactive ingredient in marijuana - tetrahydrocannabinol (TCH) - that is linked to stronger nicotine addiction among laboratory rats. THC has been of great interest to scientists, doctors and patients with chronic pain...
Kinase Inhibitors Could Keep Cancer Patients Alive For Much Longer
Date: Mar-18-2013Kinase inhibitors, a class of cutting-edge cancer medications, could keep patients alive for far longer than is currently possible after scientists from the University of Sussex and The Institute of Cancer Research, England, discovered how they attack tumors. In what they describe as an "unexpected and exciting finding"- discovering the mechanism of action of these drugs - the researchers believe they can unlock the true potential of kinase inhibitors by altering the way they are used...
Study Opens Promising New Direction In Autism Research
Date: Mar-18-2013Autism Speaks, the world's leading autism science and advocacy organization, has announced a study supported by one of Autism Speaks' first Suzanne and Bob Wright Trailblazer Awards, presents a new theory that autism may result from chronic danger signaling by mitochondria, cell structures that supply our cells with energy. This study by Trailblazer researcher and mitochondrial medicine specialist Robert Naviaux, M.D., Ph.D., of the University of California, San Diego published in the journal PLOS-ONE supports a novel theory about the cause and potential treatment of autism...
