New Prostate Cancer Screening Test Shows Promise
Date: Aug-10-2012According to a new study published in the Journal of Urology researchers at NewYork-Presbyterian Hospital and Weill Cornell Medical Center have successfully developed and tested a new prostate cancer-screening test. The test is a combination of a novel drug therapy and PSA level changes over time in order to identify men with a high PSA who have a higher risk of developing aggressive prostate cancer even though they had negative biopsies...
Living In The Moment Is Not Possible According To Neuroscientists
Date: Aug-10-2012Neuroscientists have discovered that the universal saying of "living in the moment" may be impossible. A study published in the journal Neuron reveals that neuroscientists have identified an area in the brain, which is responsible for using past decisions and outcomes to guide future behavior. The study is the first of its kind to analyze signals linked to metacognition, known as a person's ability to monitor and control cognition, which researchers describe as "thinking about thinking...
Osteoarthritis Patients Benefit From Exercise And Weight Loss
Date: Aug-10-2012A $3 million grant, from the National Institute of Aging, has been given to the University of Illinois at Chicago to analyze the effects of two community-based promotion programs for older people struggling with osteoarthritis. Fit and Strong!, an evidence-based physical activity and health behavior change program, will be compared with Fit and Strong! Plus, a more traditional program with an added weight management/dietary component...
Circuits In The Brain Reveal Why Neurological Disorders Occur
Date: Aug-10-2012The human brain contains billions of neurons that are arranged in complex circuits, which enable people to function with regard to controlling movements, perceiving the world and making decisions. In order to understand how the brain works and what malfunctions occur in neurological disorders it is crucial to decipher these brain circuits...
Long-Term Alcohol Abuse Affects Men And Women Differently
Date: Aug-10-2012Researchers from Boston University School of Medicine (BUSM) and Veterans Affairs (VA) Boston Healthcare System have discovered that men and women recover differently from alcohol abuse. A new study, published online in the journal Alcoholism: Clinical and Experimental Research, shows that the impact of long-term alcohol abuse on white matter brain volume is different for men and women, which indicates that women recover their white matter brain volume faster than men with abstinence...
Teens In Substance Abuse Programs Use Medical Marijuana Belonging To Others
Date: Aug-10-2012According to a new study, teenagers in substance abuse treatment often use medical marijuana recommended to someone else - "diverted" medical marijuana. The study, conducted by Stacy Salomonsen-Sautel, Ph.D., a postdoctoral fellow in the University of Colorado School of Medicine's Department of Pharmacology and her colleagues in the Department of Psychiatry, examined 164 adolescent who were in one of two substance abuse treatment programs in the Denver metropolitan area. The researchers found that 73...
Longevity Protein Has Diabetes-Prevention Qualities
Date: Aug-10-2012According to a study published in the journal Cell Metabolism, researchers at MIT have discovered that a protein, which has been shown to slow aging in animals, also protects against the detrimental effects of a high-fat diet, including diabetes. More than ten years ago, Leonard Guarente, a biology professor at MIT, discovered that the protein SIRT1 had properties that boosted longevity. Since then Guarente has investigated how the protein works in several different body tissues...
Exposure To Staph Bacteria Could Lead To Lupus
Date: Aug-10-2012Mayo Clinic research shows that chronic exposure to even small amounts of Staphylococcus aureus (staph) bacteria, which is frequently found on the skin or in the nose, could present a risk factor for developing the chronic inflammatory disease lupus. The study is published online in the August edition of The Journal of Immunology. In an animal study, the researchers exposed mice to low doses of a protein found in staph and discovered that the mice developed a disease similar to lupus, with kidney disease and auto-antibodies comparable to those found lupus patients' blood...
Epilepsy Drug Can Reverse Memory Loss In Alzheimer's Patients
Date: Aug-10-2012According to a study published online in the Proceedings of the National Academy of Sciences, an FDA-approved anti-epileptic drug has been found to reverse memory loss in a mouse model of Alzheimer's disease . The study, conducted by researchers at the Gladstone Institutes, also found that the drug, called levetiracetam, alleviates other Alzheimer's related impairments by suppressing abnormal brain activity. Levetiracetam is often prescribed to individuals who suffer from epilepsy. At present, around 5...
Child's Allergy Risk Higher If Same Sex Parent Has It
Date: Aug-10-2012Researchers have discovered an interesting fact about the genetic basis of childhood allergic diseases: a child is more likely to have a particular allergy if his or her same-sex parent has it. So for example, a girl's chance of having asthma is higher if her mother has it, and a boy's is higher if his father has it. And the same appears to be true of eczema and other childhood allergies...
