Earlier bites by uninfected mosquitoes boost West Nile deaths in lab mice

There's one more reason to try to avoid being bitten by mosquitoes, scientists have discovered: bites from mosquitoes that aren't infected by the West Nile virus may make the disease worse in people who acquire it later from West Nile-infected mosquitoes.

   Few things sting like a mosquito's bite -- especially if that bite carries a disease such as malaria, yellow fever, Dengue fever or West Nile virus. But if a team of University of Arizona researchers has its way, one day mosquito bites may prove deadly to the mosquitoes.

3. Sharks' 'bite force' researched by University of Tampa biologist
   08-23-2007 · EurekAlert!
   Dan Huber, University of Tampa assistant professor of biology, is analyzing the "bite force" and feeding mechanics of great white sharks. Earlier this summer Huber traveled to Australia to dissect a rare 8-foot great white shark, and help create the first high-res 3-D computer model of its bite. Huber's research may lead to advances in protective swimwear, shark-proofing equipment and a better understanding of flexible cartilage -- which forms the sharks' whole skeletons.

5. Compound in broccoli could boost immune system, says new study
   08-20-2007 · EurekAlert!
   A compound found in broccoli and related vegetables may help boost the immune system, according to a new UC-Berkeley-led study. Researchers found that mice fed mice a solution of the compound, 3,3'-diindolylmethane, had increased blood levels of cytokines -- proteins which help regulate the cells of the immune system -- and were better able to clear reoviruses from their intestines.

   New data from UF and the Florida Department of Law Enforcement show that since 2000 cocaine has increasingly been cited as the cause of death in coroner's reports, and that the number of cocaine deaths per 100,000 people in the state has nearly doubled in the past five years, from 150 in 2000 to nearly 300 in 2005.

7. Gene therapy a possibility for metachromatic leukodystrophy?
   11-01-2006 · EurekAlert!
   There are currently no therapies for metachromatic leukodystrophy, which causes progressively more severe neurological defects that result in death early in life. Individuals with MLD lack the protein ARSA. A new study shows that the neurological defects in mice lacking ARSA can be corrected by treatment with hematopoietic stem progenitor cells genetically modified to express ARSA, leading to the suggestion that HSPC gene therapy might be efficacious for the treatment of MLD.

10. Inflammation may cause preterm labor and fetal deaths
    08-08-2007 · EurekAlert!
    Inflammation from bacterial infections is linked to preterm births and deaths, according to researchers from Case Western Reserve University's School of Dental Medicine and the Case School of Medicine. They found if receptors responding to the presence of dead or living bacteria in the placentas of mice can be blocked, the number of preterm deaths will decline by nearly half.
