Silencing the TLR4 gene can stop the process which may lead to cardiovascular disease in diabetic patients. Researchers writing in BioMed Central's open access Journal of Translational Medicine carried out a series of in vitro tests which demonstrated that TLR4 plays a critical role in hyperglycaemic cardiac apoptosis, and that silencing the gene using specific small interfering RNA (siRNA) can prevent it.

Doctors often ask kidney disease patients on dialysis to limit the amount of phosphate they consume in their diets, but this does not help prolong their lives, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). The results even suggest that prescribing low phosphate diets may increase dialysis patients' risk of premature death.
BOSTON, Mass. (December 9, 2010)—A team of researchers from Harvard Medical School, Brigham and Women's Hospital, and Massachusetts General Hospital, with others from the United States and Haiti, has determined that the strain of cholera erupting in Haiti matches bacterial samples from South Asia and not those from Latin America. The scientists conclude that the cholera bacterial strain introduced into Haiti probably came from an infected human, contaminated food or other item from outside of Latin America.
Menlo Park, Calif. – December 9, 2010 – Scientists from Pacific Biosciences of California, Inc. (NASDAQ: PACB) and Harvard Medical School have successfully employed single molecule, real-time (SMRT™) DNA sequencing technology to rapidly characterize the pathogen responsible for the recent deadly cholera epidemic in Haiti. Published Thursday in the New England Journal of Medicine, the results provide the first whole genome sequence analysis and most detailed genetic profile to date of the Haitian Vibrio cholerae outbreak strain.
Using a new gene sequencing method, a team of researchers led by scientists from Johns Hopkins and the National Institutes of Health has discovered a gene that appears to cause some instances of familial amyotrophic lateral sclerosis (ALS). The finding could lead to novel ways to treat the more common form of this fatal neurodegenerative disease, which kills the vast majority of the nearly 6,000 Americans diagnosed with ALS every year.
Whether in a hurricane, tornado, or bomb attack, a leading cause of injury and death is often fast-flying shards of glass. Explosions and high winds can cause windows in buildings to shatter-spewing jagged pieces of glass in every direction.
A Pentagon report on the 1996 Khobar Towers bombing in Saudi Arabia, for example, noted:
A collaborative, government-led effort to guide and standardize diagnosis, treatment and management of food allergies has resulted in the release of an official set of recommendations for physicians.
Using buprenorphine instead of methadone — the current standard of care — to treat opioid-dependent pregnant women may result in healthier babies, suggests new findings from an international team led by Johns Hopkins researchers and published in the Dec. 9 issue of the New England Journal of Medicine.
Johns Hopkins scientists have identified a previously unrecognized step in the activation of infection-fighting white blood cells, the main immunity troops in the body's war on bacteria, viruses and foreign proteins.
"It's as if we knew many of the generals, colonels and majors and now we have discovered a new officer that helps the troops carry out the right battle plan," says Joel Pomerantz, Ph.D., an assistant professor of Biological Chemistry in the Institute for Basic Biomedical Sciences and member of the Institute for Cell Engineering at Johns Hopkins.
OAK RIDGE, Tenn., Dec. 9, 2010 -- A quicker and cheaper technique to scan molecular databases developed at the Department of Energy's Oak Ridge National Laboratory could put scientists on the fast track to developing new drug treatments.
A team led by Jerome Baudry of the University of Tennessee-ORNL Center for Molecular Biophysics adapted a widely used existing software to allow supercomputers such as ORNL's Jaguar to sift through immense molecular databases and pinpoint chemical compounds as potential drug candidates.
Researchers at the Virginia Bioinformatics Institute at Virginia Tech have discovered how abscisic acid, a natural plant hormone with known beneficial properties for the treatment of disease, helps fight inflammation. The results (http://www.ncbi.nlm.nih.gov/pubmed/210882970), which are published in the November 2010 Journal of Biological Chemistry, reveal important new drug targets for the development of treatments for inflammatory and immune-mediated diseases.
Scientists at the Virginia Bioinformatics Institute at Virginia Tech have discovered some of the key molecular events in the immune system that contribute to inflammatory bowel disease. The results, which help researchers move one step further in their efforts to develop new drugs to treat inflammatory and immune-mediated diseases, are reported in the November 2010 edition (http://www.ncbi.nlm.nih.gov/pubmed/21068720) of the journal Mucosal Immunology from the Nature Publishing Group.
Scientists have sequenced the genome of a major fungal disease that affects barley and other cereal crops, a breakthrough that could lead to significant advances in our understanding of how plant diseases evolve. The research, published today in the journal Science, suggests that parasites within the genome of the fungus help the disease to adapt and overcome the plant's defences.
Norwich scientists are on the trail of some of the most economically damaging organisms that infect crops worldwide. Their latest targets are the parasitic water fungus that causes powdery mildew and the water molds that cause late blight in potatoes and tomatoes and downy mildew in cruciferous vegetables and other crops.
