Genetic Screening During Pregnancy Shows Promise
Date: Jun-08-2012According to a study published in Science Translational Medicine, researchers at the University of Washington have successfully reconstructed the whole genome sequence of a human fetus by analyzing blood samples from the mother and saliva samples from the father. The researchers findings open up the possibility of assessing a fetus non-invasively for all single-gene disorders. Approximately 1% of newborns are born with disorders that are caused by a defect in a single gene. These "Mendelian" disorders include cystic fibrosis, Huntington's disease, and Tay-Sachs disease...
Can TV Undermine Self-Esteem In Children? Sometimes

Girls With Anxiety Have Harder Working Brains
Date: Jun-08-2012Researchers at Michigan State University have found that brains of anxious girls work significantly harder than brains of boys when put in stressful situations. The study is published in the International Journal of Psychophysiology. The researchers enrolled 79 female students and 70 male students to participate in the study in order to measure the correlation between worrying and error-related brain responses. Study participants were asked to figure out the middle letter in a group of five letters while their brain activity was measured by an electrode cap...
Scientists Say They Found A Stem Cell That Causes Heart Disease
Date: Jun-08-2012UC Berkeley scientists published a report this week in the journal Nature Communications saying that they have isolated a type of stem cell that causes heart disease in later life. The research is profound because it contradicts much of the generally accepted theories of what causes arterial hardening, and the concept may also relate to many other diseases could the associated stem cells be pinpointed...
Too Much Exercise Not As Beneficial As Moderate Training
Date: Jun-08-2012Although regular moderate exercise improves longevity, cardiovascular health and is effective at preventing many common chronic diseases, extreme endurance exercise may lead to myocardial injury, say researchers. The study, published in the June issue of Mayo Clinic Proceedings, found that training for, and competing in marathons, very long distance bicycle rides, and iron man distance triathlons, may result in structural changes to the heart and large arteries, leading to myocardial injury. Micah True a 58 year-old legendary ultra-marathoner, would run as far as 100 miles in a day...
Zytiga - New Prostate Cancer Drug
Date: Jun-08-2012Results from a phase III trial reveal that men with advanced prostate cancer can significantly benefit from a new medication, abiraterone acetate, called Zytiga. The researchers found that the drug maintained patients' quality of life, slowed down the spread of cancer, and delayed the development of pain and deterioration of the patients' overall condition. During the trial, individuals assigned to placebo were allowed to switch to zytiga because of the favorable results...
Drug Use In Depressed Adolescents May Be Prevented With Prozac
Date: Jun-08-2012Adolescents who receive prozac for the treatment of major depression are significantly less likely to abuse drugs in the future, say researchers. However, the medication did not reduce the chances of alcohol abuse. The 5-year study, conducted by John Curry, a professor of psychology and neuroscience at Duke University, involved nearly 200 adolescents at 11 sites across the United States. The researchers found that of the 192 teenagers whose depression receded after 12 weeks of treatment, only 10% abused drugs later on vs. 25% of adolescents who didn't respond to treatment...
Hospital Safety - US Hospitals Graded From A To F
Date: Jun-08-2012The Leapfrog Group has issued a ratings list of 2,652 hospitals in the USA, with "A" being the safest and "F" meaning the worst score. The authors of the report explained that hospital errors cause the death of about 400 patients each day in the United States; the equivalent of a large jet plane full of passengers crashing every day. The Leapfrog Group, a non-profit, independent organization run by purchasers and employers of health benefits, created the Hospital Safety Score, which is based on patient safety. The organization says its league table is the first of its kind...
The Power Of Suggestion
Date: Jun-08-2012A lucky rabbit foot. A glass of wine. A pill. What do these things all have in common? Their effects - whether we do well on a test, whether we mingle at the cocktail party, whether we feel better - all depend on the power of suggestion. In a new article, psychological scientists Maryanne Garry and Robert Michael of Victoria University of Wellington, along with Irving Kirsch of Harvard Medical School and Plymouth University, delve into the phenomenon of suggestion, exploring the intriguing relationship between suggestion, cognition, and behavior...
New Drug Effective In Treating Skin Cancer
Date: Jun-08-2012A new drug has been shown to be effective in treating and preventing the most common cancer in the United States: basal cell carcinoma skin cancer, according to a new study in the New England Journal of Medicine. The drug, vismodegib (trade name: Erivedge), was tested in a clinical trial in patients with Gorlin syndrome, a rare disease in which individuals have tens to hundreds of disfiguring basal cell carcinoma tumors...
