Deworming Drug Could Help Reduce Spread Of HIV In Africa, Study Finds
Providing girls in rural Africa with a deworming drug could help reduce the spread of HIV, according to a study recently published in PLoS Neglected Tropical Diseases, the New York Times reports. The drug, called praziquantel, costs about 32 cents per pediatric dose and prevents schistosomiasis, a worm disease that starts as a urinary tract infection. If untreated, schistosomiasis can lead to female genital sores that can facilitate HIV infection. Because the drug can kill the worms but cannot cure genital sores, girls should be protected before they reach sexual maturity, according to the Times. "For this relatively small investment, the reproductive health of young women would be improved," the authors from the Sabin Vaccine Institute, Imperial College London and Oslo University wrote, adding that "there is a reasonable chance that HIV/AIDS transmission can be reduced." There are about 207 million schistosomiasis cases worldwide, 90% of which occur in Africa, where humans are exposed usually through snail-infested water. According to a pilot program conducted in Burkina Faso, all 70 million cases among young children in Africa could be treated for $22 million, and repeating universal treatment every two years for 10 years would cost $112 million (McNeil, New York Times, 5/26).

Report On Contaminated Drinking Water At Camp Lejeune
Two chemicals - trichloroethylene (TCE) and tetrachloroethylene (PCE) - found to have contaminated drinking water at Marine Corps Base Camp Lejeune from the 1950s to 1985 have been linked to certain diseases and disorders, including various cancers. A new report from the National Research Council, Contaminated Water Supplies at Camp Lejeune - Assessing Potential Health Effects, reviews scientific evidence about the potential adverse health effects that could occur after exposure to TCE, PCE, and other contaminants; recommends the usefulness of conducting additional studies on former residents of the base; and identifies scientific considerations that could help the U.S. Department of the Navy, under which the Marine Corps operates, set priorities on future actions. The report will be released at a 90-minute public briefing.

Brain Neural Circuit Formation Requires Identification Of A Key Molecular Pathway

The research group of Dr. Frçİdçİric Charron, a researcher at the Institut de recherches cliniques de Montrçİal (IRCM), has made a discovery which could help treat spinal cord injuries and neurodegenerative diseases. This new finding has been published in the current issue of the prestigious scientific journal Neuron. Patricia T. Yam, Sçİbastien D. Langlois and Steves Morin, all at the IRCM, are listed as co-authors. The brain is composed of billions of interconnected neurons. To correctly form neuronal circuits, the developing axons (a long extension of a neuron) require attractive and repulsive molecules to lead them to their appropriate targets. One such molecule is Sonic Hedgehog (Shh). Five years ago, as a postdoctoral fellow in the laboratory of Dr. Marc Tessier-Lavigne at Stanford University, Frçİdçİric Charron discovered that Shh acted as an axonal attractant for brain and spinal cord neurons. "How exactly Shh elicited this effect has remained unknown so far," pointed out Dr. Charron. "The molecular pathway my team discovered provides part of an answer." Their recent work showed that Shh exerts its attractive effect through a group of molecules called Src family kinases (SFKs) that, until now, were not known to be linked to Shh function. Remarkably, these novel Shh effector molecules are absolutely required for the ability of Shh to guide axons. Connecting axons with an appropriate set of targets is very complex. Inappropriate wiring or damage to these neuronal connections leads to severe abnormalities of the nervous system. "Knowing the effectors of axon guidance molecules such as Shh", adds Dr. Charron, "helps us to understand the molecular mechanisms by which axons reach their target. It paves the way to new therapies to treat spinal cord injuries, neurodevelopmental disorders, and neurodegenerative diseases." This new discovery was made possible through the invention of a novel technique to control and observe the behavior of axons in response to guidance molecules. A patent application for this technique has been filed recently. This invention is expected to speed up the discovery of drugs that control axon pathfinding. "Dr. Charron is one of the country"s leading newly arrived neuroscientists. This research has important long-term implications for the repair of spinal cord injury: if we knew all of the molecules required to guide axons correctly during spinal cord healing, we would probably know how to heal spinal cord injuries," says Dr. Rod McInnes, Scientific Director of the Canadian Institutes of Health Research Institute of Genetics. "This is beautiful research that adds another major brick to our building a complete understanding of how the spinal cord is made, and how injury of it can be treated." This work was supported by grants from the Canadian Institutes of Health Research (CIHR), the Canadian Foundation for Innovation (CFI), the McGill Program in Neuroengineering, the Fonds de recherche en santçİ du Quçİbec (FRSQ) and the Peter Lougheed Medical Research Foundation.
