South America's vast pantanal wetland may become next everglades, UNU experts warn

...anal is the world's largest freshwater wetland, of active interest to U.S. scientists for insights into the lost biodiversity of Florida's famed Everglades, altered by drainage projects starting in the 1940s to make way for development and agriculture. In a message to mark World Water Day, March 22, UNU sa...

Rush Physicians Using Gene Therapy For Heart Patients With Moderate To Severe Chest Pains Who Do Not Benefit From Other Treatments

...placebo. For every three patients that receive the active gene, one will receive a placebo. Following treatment, patients enrolled in the study will be examined for chest pain at one month, three months and six months. A total of 404 patients will be enrolled in the study at the 20 study sites across the co...

Protein offers way to stop microscopic parasites in their tracks

...parasite used at least four of those genes to make active proteases. When they looked at where and when Toxoplasma made the proteases, they found that only one, TgROM5, consistently showed up at the back end of the parasite, where it would be ideally positioned to snip off the adhesive protein spots. Cell ...

Scientists discuss improved biopesticides for locust control in West Africa

...ocust biopesticides may be used. Vaughan has been active in locust control since 1997, when he assumed coordination of the USAID-funded project at Virginia Tech, "Development of Biopesticides for Grasshopper and Locust Control in Sub-Saharan Africa," which wrapped up in June 2004. Agblevor participated in ...

Hirsute Or Hairless? Two Proteins May Spell The Difference

...ons diminishes. By identifying which molecules are active in specific cell types at specific developmental stages, this study lays the foundation for dissecting the mechanisms that connect two key processes—intercellular remodeling and proliferation—in epithelial development. And since the consequences of T...

More than 1,000 products from multinational and local companies were considered for this recognition. The judging panel commented, "Chemical fibe...

Antiretroviral therapy may prevent excess risk of some cancers in people with HIV

...ed with human immunodeficiency virus (HIV), highly active antiretroviral therapy (HAART) may prevent most excess cases of Kaposi sarcoma and non-Hodgkin lymphoma, according to a new study in the March 16 issue of the Journal of the National Cancer Institute. Studies of people with acquired immunodeficiency...

Viral protein influences key cell-signaling pathway

...lar genes out of 33,000 become either more or less active due to the p12 protein. The researchers found that p12 altered the activity of a variety of genes linked to chemical pathways that control cell signaling, proliferation and death. The p300 gene stood out as one showing increased activity. Taken over...

Insight into natural cholesterol control suggests novel cholesterol-lowering therapy

...tase activity, contributing to a major increase in active reductase that becomes progressively harder to control, according to the researchers. The new findings suggest that drugs that mimic lanosterol--given along with statins--may improve the drugs' long-term ability to lower cholesterol by stimulating re...

Discovery may lead to better Candidiasis drug

...esults showed that histatin was significantly less active when the suspect target was missing. Further research indicated that histatin binding to the target protein killed the fungal cells by preventing it from regulating its ions, the positive and negative charged molecules that move into, and out of, ce...

Defenseless plants arm themselves with metals
