Study finds mercury prevalent in many western fish

...ds, such as rainbow and cutthroat trout, which had lower levels of mercury. Results of the study were published earlier this month in the journal Environmental Science and Technology. The researchers say the risk for humans who may occasionally eat fish from the streams is fairly low and they compare...

Protein therapy may reduce infarct size in heart attack patients

...y be associated with less myocardial necrosis with lower CK-MB AUC values at all dose levels. Furthermore, improved tissue perfusion (measured during coronary angiography after stent implantation and by continuous electrocardiogram recordings) and reduced infarct size (measured 14 days after the heart atta...

Anti-fungal drug stops blood vessel growth

...growing, because related antifungal drugs had much lower inhibitory effect. “Our screening test did show that cholesterol-lowering statins also appear to stop blood vessel growth,?Liu says, “so there is likely some important connection between cholesterol and angiogenesis.? While the researchers sti...

Stem cell therapy shows promise in regenerating damaged muscle in heart attack patients

...s adult stem cell therapy, Provacel? experienced a lower number of adverse events, such as cardiac arrhythmias, and had significant improvements in heart, lung and global function compared to those who received a placebo, according to six-month Phase I study data presented at the American College of Cardio...

Minuscule molecules pack a powerful punch

... bacteria than mice with normal miR-155, producing lower levels of antibody and a reduced response by T-cells. They also develop changes to lung tissue, with scarring that is similar to some human systemic autoimmune disorders. To uncover how miR-155 might cause such widespread disruption of the immune ...

Magic Beans -- Anti-obesity soya could help prevent diabetes

...ich in black soya beans could help control weight, lower fat and cholesterol levels, and aid in the prevention of diabetes, reports Lisa Richards in Chemistry & Industry, the magazine of the SCI. Yellow soya has already been hailed for its cholesterol lowering capabilities; this is one of the reasons ...

Opening windows may be the best way of preventing transmission of airborne infection

...ilation and that the risk of airborne contagion is lower than with mechanical ventilation systems. Old-fashioned clinical areas with high ceilings and large windows provided the greatest protection. In a related perspective article Peter Wilson, from University College London, concludes that although “n...

Brain tissue reveals possible genetic trigger for schizophrenia

Scientists identify a candidate gene for osteoporosis

...e DARC -knockout mice exhibited increased BMD and lower bone resorption compared to mice with the DARC gene, supporting the predicted role of DARC in hastening bone resorption. They also showed that antibodies to the DARC protein, which effectively blocked the action of DARC , inhibited the format...

Novel laboratory technique nudges genes into activity

...rned off, but rather, the levels of expression are lower than they should be," she said. As a result, there is an inadequate amount of a particular protein in the body. "If we can bring the level up a few notches, we might actually treat or cure the disease," Dr. Janowski said. For example, some genes a...

'Exercise pill' switches on gene that tells cells to burn fat

New approach could lower antibiotic requirements by 50 times

... for treating cases of food poisoning, because the lower doses of antibiotic needed would not disrupt the friendly bacteria in the gut - a big problem with conventional antibiotic treatments. 'The prospect of using such treatments to prolong the life of existing agents and delay the onset of widespread r...

Overfishing large sharks impacts entire marine ecosystem, shrinks shellfish supply

"Despite the difficulty of piecing together ecosystem impacts of overfishing," co-author Travis Shepherd of Dalhousie emphasizes, "the real challenge will be to move beyond retrospective analyses and instead prevent ecosystem-wide...

Pharmaceutical compounds found in nation's fresh water

...ions in one liter of ground water are usually much lower than a typical human therapeutic dose," says lead author Emily Godfrey. While such low concentrations do not appear to pose a threat to human health, this research may help frame policy on the disposal of expired or unused compounds. ...

Investment level in HIV prevention programs related to HIV incidence in the United States

...d HIV incidence since the mid-1980s. If we want to lower infections further in the U.S., these analyses suggest we should consider increasing our national investment. Yes, that may seem expensive, but HIV medical care easily tops $20,000 per patient per year. Therefore, funding of effective, scientifically...
