How Humans Could Benefit From Unusual Antibodies Discovered In Cows
Date: Jun-11-2013Humans have been raising cows for their meat, hides and milk for millennia. Now it appears that the cow immune system also has something to offer. A new study led by scientists from The Scripps Research Institute (TSRI) focusing on an extraordinary family of cow antibodies points to new ways to make human medicines. "These antibodies' structure and their mechanism for creating diversity haven't been seen before in other animals' antibodies," said Vaughn V...
Under-Use Of Genetic Testing Puts Health Of Entire Families At Risk
Date: Jun-11-2013A new study of the use of genetic testing for cancer-causing mutations in affected families in France has found that its take-up is very low...
Vegetable Fats Reduce Prostate Cancer Death Risk
Date: Jun-11-2013Prostate cancer patients who replace animal fats and some carbohydrates with vegetable fats have a lower risk of premature death, researchers from the University of California reported in JAMA Internal Medicine. In the United States alone, nearly 2.5 million men currently live with prostate cancer. Not much is known about how diet may influence prostate cancer progression and death rates, the authors wrote as background information. Erin L. Richman, Sc.D...
Study Sheds Light On Origin Of Wide Range Of Brain Disorders
Date: Jun-11-2013Researchers at Weill Cornell Medical College have uncovered a mechanism that guides the exquisite wiring of neural circuits in a developing brain -- gaining unprecedented insight into the faulty circuits that may lead to brain disorders ranging from autism to mental retardation. In the journal Cell, the researchers describe, for the first time, that faulty wiring occurs when RNA molecules embedded in a growing axon are not degraded after they give instructions that help steer the nerve cell...
Social Media Analysis Tool Making Sense Of Patterns In The Twitterverse
Date: Jun-11-2013If you think keeping up with what's happening via Twitter, Facebook and other social media is like drinking from a fire hose, multiply that by 7 billion - and you'll have a sense of what Court Corley wakes up to every morning. Corley, a data scientist at the Department of Energy's Pacific Northwest National Laboratory, has created a powerful digital system capable of analyzing billions of tweets and other social media messages in just seconds, in an effort to discover patterns and make sense of all the information...
CT Scans Associated With Increased Cancer Risk
Date: Jun-11-2013An analysis of seven healthcare systems in the U.S. has found that pediatric radiation exposure from CT scans can potentially double the risk of cancer caused by radiation. The study, published in the journal JAMA Pediatrics, revealed that the number of CT scans among young children has more than doubled from 1996 to 2005. Scans rose from about 330,000 in 1995 to 1.65 million in 2008, a five-fold increase, indicating that over the past several years the use of CT scans in pediatrics has shot up. CT scanning produces multiple images or pictures of the inside of the body...
Doctors Increasingly Unclog Heart Arteries Via The Wrist
Date: Jun-11-2013Doctors from around the world are unclogging blocked arteries in the heart by entering through blood vessels in the wrist instead of the groin, and U.S. doctors are slowly following suit, a new study reveals. The study, published in the journal Circulation, suggests that entering the radial artery in the wrist is associated with fewer bleeding complications than the traditional way through the femoral artery in the groin. Lead author Dr...
FDA Approves Sanofi's 4-Strain Influenza Vaccine
Date: Jun-11-2013The U.S. Food and Drug Administration has just announced the approval of the first and only 4-strain influenza vaccine for children as young as 6 months. Sanofi Pasteur, the vaccines division of the French drugmaker Sanofi, said its Fluzone Quadrivalent vaccine provides better protection from flu compared to the older three-strain vaccines. The vaccine will be one the first of its kind available in this year's upcoming flu season, along with GlaxoSmithKline's four-strain seasonal flu vaccine, called Fluarix Quadrivalent...
Concerns About 'Designated Drivers'
Date: Jun-11-2013Maybe better call that cab, after all: A new University of Florida study found that 35 percent of designated drivers had quaffed alcohol and most had blood-alcohol levels high enough to impair their driving. Adam Barry, an assistant professor of health education and behavior at UF, and his team interviewed and breath-tested more than 1,000 bar patrons in the downtown restaurant and bar district of a major university town in the Southeast. Of the designated drivers who had consumed alcohol, half recorded a blood-alcohol level higher than ...
Older Fathers More Likely To Pass On Genetic Mutation To Their Children
Date: Jun-11-2013Genetic mutation of a testis stem cell actually gives the disease an edge, making older fathers more likely to pass it along to their children Scientists at USC have unlocked the mystery of why new cases of the genetic disease Noonan Syndrome are so common: a mutation that causes the disease disproportionately increases a normal father's production of sperm carrying the disease trait. When this Noonan syndrome mutation arises in a normal sperm stem cell it makes that cell more likely to reproduce itself than stem cells lacking the mutation...
