Researchers report new pro-inflammatory role for anti-inflammatory enzyme

...ne system's pro-inflammatory response to bacterial invasion is to increase nitric oxide levels with an enzyme called inducible nitric oxide synthase. In a study published in the Journal of Biological Chemistry, scientists report that the predominantly anti-inflammatory enzyme, endothelial nitric oxide synthas...

Light therapy may combat fungal infections, new evidence suggests

...ngs suggest that changes in light following fungal invasion of the human body may be an important and previously overlooked cue that sparks infection, the researchers said. The discovery in the human pathogen Cryptococcus neoformans further suggests that light therapy, in combination with anti-fungal drug tr...

Scientists discuss improved biopesticides for locust control in West Africa

...es developed at Virginia Tech during the secondary invasion of locusts that is expected in 2005. Agblevor discussed long-term formulation research that could expand the circumstances under which locust biopesticides may be used. Vaughan has been active in locust control since 1997, when he assumed coordinati...

Protein offers way to stop microscopic parasites in their tracks
