New Findings Help Pinpoint Autism’s Genetic Roots May 3, 2006
By deleting a gene in certain parts of the brain, researchers at UT Southwestern Medical Center have created mice that show deficits in social interaction that are reminiscent of humans with autism spectrum disorders.
Early Use Of Statins After Coronary Syndromes Does Not Reduce Risk Of Heart Attack, Stroke Or Death
Beginning use of statins within 14 days of acute coronary syndromes (such as heart attack or unstable angina) does not decrease the risk of death, heart attack, or stroke, for up to 4 months, based on a meta-analysis of previously published studies, according to an article in the May 3 issue of JAMA.
In Túngara Frogs, Female Choice For Complex Calls Led To Evolution Of Unusual Male …
Male tropical túngara frogs have evolved masses on their vocal cords that help them woo females with complex calls, show scientists working at the Smithsonian Tropical Research Institute (STRI) in Panama.
Could A Popular HIV Drug Benefit Hepatitis B Patients?
Saint Louis University School of Medicine researchers are studying the effectiveness of a drug for patients with chronic hepatitis B that is currently used to treat HIV.
Salk Scientists Untangle Steroid Hormone Signaling In Plants
When given extra shots of the plant steroid brassinolide, plants "pump up" like major league baseball players do on steroids. Tracing brassinolide’s signal deep into the cell’s nucleus, researchers at the Salk Institute for Biological Studies have unraveled how the growth-boosting hormone accomplishes its job at the molecular level.
Should Older Men Be Screened For Prostate Cancer?
Although guidelines suggest men 75 years or older may not benefit from prostate cancer screening, surveys continue to show high rates of screening in this population. A population-based cohort study published in the May issue of The American Journal of Medicine, researchers followed men 75 to 84 who had been diagnosed with clinically localized prostate cancer. Results reinforce concerns that men 75 years and older may not benefit from prostate cancer screening because of adverse outcomes from aggressive treatment.
Hubble Snaps Baby Pictures Of Jupiter’s ‘Red Spot Jr.’
NASA’s Hubble Space Telescope is giving astronomers their most detailed view yet of a second red spot emerging on Jupiter. For the first time in history, astronomers have witnessed the birth of a new red spot on the giant planet, which is located half a billion miles away. The storm is roughly one-half the diameter of its bigger and legendary cousin, the Great Red Spot.
New Treatment Allow Patients To Return To Pre-injury Activity
Ultrasound-guided, intra-tendonous injection of a dextrose solution is a very effective treatment for certain chronic tendonoses in the leg, reported radiologists from the department of radiology at St. Paul’s Hospital and the Department of Family Practice at the University of British Columbia both in Vancouver, BC.
Key Root-development Pathway Mapped Using Advanced Genomic Technique
Biologists have vastly expanded understanding of the biological machinery controlling the intricate process by which plant roots burgeon from single cells into complex tissues. A Duke-led team’s discovery of new components of the root-development pathway in the mustard plant, Arabidopsis thaliana, represents both a scientific and technical achievement, the scientists said.
Study Shows Newborns With Jaundice At No Greater Risk
Newborn babies who are diagnosed with and treated for jaundice are no more likely than other babies to suffer long-term developmental problems, according to a study published in the New England Journal of Medicine.
