Genetic variation associated with lower risk of sudden cardiac arrest:Study

Physician-scientists at the Cedars-Sinai Heart Institute have found that a genetic variation is associated with lower risk of sudden cardiac arrest, a disorder that gives little warning and is fatal in about 95 percent of cases. Findings will be published tomorrow by the Public Library of Science (PloS One).

Prior knowledge of impending distraction does not improve memory performance in older adults

One of the most common complaints among healthy older adults relates to a decline in memory performance. This decline has been linked to an inability to ignore irrelevant information when forming memories.

Study on zebrafish regenerate tissues links human heart implications

In a paper published in the March 25, 2010 issue of Nature, researchers working at the Salk Institute for Biological Studies and the Center of Regenerative Medicine in Barcelona (CMRB) identified a fish heart cell population that is the source of this astonishing healing feat, a finding that could provide insight into how mammalian hearts might be coaxed into repairing themselves after injury brought on by heart attack.

Campylobacter cells can survive with biofilm protection

In research published in the journal Applied and Environmental Microbiology, IFR researchers have found that Campylobacter will readily form a biofilm under laboratory conditions, and that, when the bacteria were left in air, they respond to these stressful conditions by more rapidly forming this biofilm.

Bariatric surgery may delay onset of type 2 diabetes, says study

A team of researchers, led by a UC Davis veterinary endocrinologist, has shown for the first time that a surgical procedure in rats that is similar to bariatric surgery in humans can delay the onset of type 2 diabetes.

Study offers new insight on how human brain makes moral judgments

A new study from MIT neuroscientists suggests that our ability to respond appropriately to intended harms - that is, with outrage toward the perpetrator - is seated in a brain region associated with regulating emotions.

Special medicated contact lenses can help treat common eye disorders

The popular dietary supplement vitamin E, loaded into special medicated contact lenses, can keep glaucoma medicine near the eye - where it can treat that common disease- almost 100 times longer than possible with current commercial lenses, scientists reported here today.

Study: MetAP inhibitors prevent TB growth in test tubes

Suspecting that a particular protein in tuberculosis was likely to be vital to the bacteria's survival, Johns Hopkins scientists screened 175,000 small chemical compounds and identified a potent class of compounds that selectively slows down this protein's activity and, in a test tube, blocks TB growth, demonstrating that the protein is indeed a vulnerable target.

Protein deficiency in Down syndrome patients could contribute to cognitive impairment and congenital heart defects

Conventional wisdom among scientists for years has suggested that because individuals with Down syndrome have an extra chromosome, the disorder most likely results from the presence of too many genes or proteins contained in that additional structure.

Breathing diesel exhaust during pregnancy linked with sluggishness in offspring

Breathing diesel exhaust during pregnancy is associated with sluggishness in offspring. Researchers writing in BioMed Central's open access journal Particle and Fibre Toxicology studied the effects of pollution exposure in mice, finding that the offspring of mothers who breathed diesel fumes while pregnant were less likely to show spontaneous movement.
