JUPITER, FL, November 9, 2010 – For Immediate Release – Scientists from the Florida campus of The Scripps Research Institute have identified for the first time a novel mechanism that regulates circadian rhythm, the master clock that controls the body's natural 24-hour physiological cycle. These new findings could provide a new target not only for jet lag, shift work, and sleep disturbances, but also for disorders that result from circadian rhythm disruption, including diabetes and obesity as well as some types of cancer.
MAYWOOD, Ill. -- Alcohol does much more harm to the body than just damaging the liver. Drinking also can weaken the immune system, slow healing, impair bone formation, increase the risk of HIV transmission and hinder recovery from burns, trauma, bleeding and surgery.
Researchers released the latest findings on such negative effects of alcohol during a meeting Nov. 19 of the Alcohol and Immunology Research Interest Group, held at Loyola University Medical Center.
Both the bully and the victim's individual characteristics, rather than the wider social environment, explain why bullying occurs, according to Swedish teenagers. The new study, by Dr. Robert Thornberg and Sven Knutsen from Linköping University in Sweden, also shows that 42 percent of teenagers blamed the victim for the bullying. The study is published online in Springer's journal, Child & Youth Care Forum.
After four years of conducting intensive calculations in the supercomputer MareNostrum at the Barcelona Supercomputing Center, scientists headed by Modesto Orozco at the Institute for Research in Biomedicine (IRB Barcelona) have presented the world's largest data base on protein motions. Called MoDEL, this new database holds more than 1,700 proteins and is partially accessible through Internet to researchers worldwide. MoDEL has been developed to study the basic biology of proteins and to accelerate and facilitate the design of new pharmaceutical agents.
Millions will escape hunger and poverty in a widening campaign to achieve global food security and deliver major environmental gains within 25 years
Can a heart implanted micro robot operate permanently? Can cell phones and tiny robots implanted in the heart operate permanently without having their batteries charged?
It might sound like science fiction, but these things seem to be possible in the near future.
A new study finds that an FDA-approved drug to treat the rare autoimmune disorder immune thromobocytopenia (ITP) is more effective than earlier medical therapies in helping patients avoid surgical treatment and significantly improving their quality of life. The paper in the Nov. 11 New England Journal of Medicine reports that treatment with romiplostim, which mimics the effects of a growth factor that regulates platelet production, was more than three times more successful than standard therapy with steroids or immunosuppressive drugs.
Decoding the DNA of a woman who died of acute myeloid leukemia (AML) has led researchers at Washington University School of Medicine in St. Louis to a gene that they found to be commonly altered in many patients who died quickly of the disease.
Researchers have discovered mutations in a particular gene that affects the treatment prognosis for some patients with acute myeloid leukemia (AML), an aggressive blood cancer that kills 9,000 Americans annually. The scientists report their results in the Nov. 11, 2010, on-line issue of The New England Journal of Medicine.
ST. PAUL, Minn. – Contrary to earlier research, a new, long-term study suggests that cholesterol level in mid-life may not be linked to later development of Alzheimer's disease, according to a study published in the November 10, 2010, online issue of Neurology®, the medical journal of the American Academy of Neurology. However, the results suggest that large decreases in cholesterol levels in old age could be a better predictor of developing the memory-robbing disease.
Men taking androgen deprivation therapy (ADT) for prostate cancer may have an increased risk of colorectal cancer, according to a study published online November 10 in The Journal of the National Cancer Institute.
Androgen deprivation therapy is a widely-prescribed treatment in men with prostate cancer, although its usage for low-risk disease remains controversial, given the adverse side effects, including osteoporosis, cardiovascular disease, diabetes and obesity; the last two are risk factors for colorectal cancer.
The Halpin Foundation and the American Society of Nephrology (ASN) proudly highlight the research advances in membranous nephropathy made possible by The Halpin Foundation-ASN Research Grant, created to help young faculty develop independent research careers. This award provides recipients transition funding toward successful application for an NIH RO1 grant.
WHAT:Newly published research by scientists at the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, sheds light on a poorly understood, acute illness called Immune Reconstitution Inflammatory Syndrome (IRIS) that develops in some HIV-infected individuals soon after they begin antiretroviral therapy.
