Blocking the nerve receptor EP1 in mouse models reduces brain damage caused by stroke

...ing holds promise for the development of effective alternatives to anti-inflammatory drugs called COX inhibitors, which have potentially lethal side effects that limit their use, says Sylvain Doré, Ph.D., an associate professor in the departments of Anesthesiology and Critical Care Medicine and Neuroscience at Th...

Amphetamines reverse Parkinson's disease symptoms in mice

...ith similar chemical attributes might offer useful alternatives to current therapies, the researchers said. The new study also shows that amphetamines -- normally thought to act by increasing dopamine concentrations in the brain ? correct the behavioral abnormalities associated with Parkinson's in mice devoid of...

Millennium Ecosystem Assessment: Many of 2 billion dryland dwellers at risk as land degrades

...on practices. Finally, creating viable livelihood alternatives for drylands populations should become part of national strategies to combat desertification and poverty reduction. The greatest vulnerability is ascribed to sub-Saharan and Central Asian drylands. For example, in three key regions of Africa--the Sa...

Scalpel-free surgery could reduce risk of HIV and hepatitis exposure for health care workers

...ry-a surgical technique which uses high-technology alternatives to needles and knives. We advocate using these techniques whenever possible in high-risk settings to further protect health care workers from accidental transmission," added Makary. Sharpless surgical techniques include laparoscopy, electrocautery t...

Green catalyst destroys pesticides and munitions toxins, finds Carnegie Mellon University

...ve suite of these catalysts to provide clean, safe alternatives to existing industrial practices, as well as ways to remediate other pressing problems that currently lack solutions. "Fe-TAMLs are much easier to use in destroying nitrophenols because they work at ambient temperatures and neutral pH," said Collin...

Engineers improve plastic's potential for use in implants by linking it to biological material

...hat attaches to polypyrrole from among the billion alternatives initially analyzed. These unique peptides were displayed on the outer surface of a harmless type of virus called a bacteriophage that was purchased commercially. To hunt for the plastic-preferring peptide, Sanghvi and Miller added a solution contain...
