Tulane Receives $7.07 Million NIH Grant To Develop Hemorrhagic Fever Virus Detection Kits
Researchers at Tulane University, in collaboration with Corgenix Medical Corporation, a worldwide developer and marketer of diagnostic test kits, have received a five-year $7,073,538 grant from the National Institutes of Health (NIH) for continued development of detection kits for Lassa viral hemorrhagic fever, a serious disease spread by contact with infected rodents. Viral hemorrhagic fevers are characterized by fever and bleeding disorders and can progress to high fever and shock. Lassa fever is estimated to infect 300,000 to 500,000 people per year across West Africa, resulting in approximately 5,000 deaths.

Segregation Decreases Access To Surgical Care For Minorities, Study Finds
New research published in the June issue of the Journal of the American College of Surgeons reveals that in counties with the highest levels of segregation, an increase in the African-American or Hispanic population was associated with a decrease in the availability and use of surgical services and an increase in the number of emergency room visits. This research supports prior studies that have shown that minority groups in the United States have comparatively poorer access to a range of health care services, often resulting in late diagnosis of illness and delayed treatment.

Advance In Detecting Melamine-adulterated Food

Researchers in Indiana are reporting an advance toward faster, more sensitive tests for detecting melamine, the substance that killed at least 6 children and sickened 300,000 children in China who drank milk and infant formula adulterated with the substance. The improved tests may ease global concerns about food safety, the researchers say. Their report is scheduled for the May 27 issue of ACS" Journal of Agricultural and Food Chemistry, a bi-weekly publication. In the new study, Lisa Mauer and colleagues note that tests already exist for melamine, which is widely used in plastics. Certain food manufacturers, however, have added melamine to food products marketed for humans and domestic pets to boost apparent protein content. Conventional tests, however, tend to be too slow, insensitive, and too complex for large-scale food screening applications. Researchers say that better detection tests are needed, particularly in the wake of new U.S. Food and Drug Administration (FDA) guidelines limiting melamine in dairy products to 1 part per million (ppm) or less. The scientists describe a trio of promising detection methods based on near- and mid-infrared spectroscopy, analytical techniques that identify a substance based on its chemical fingerprint when exposed to specific kinds of light. In laboratory studies, the scientists used these tests to screen infant formula spiked with different concentrations of melamine. They found that these methods accurately detected the substance at levels as low as 1 ppm, meeting the new FDA detection guidelines. The techniques take as little as 5 minutes to detect melamine and are relatively simple to use, requiring little or no sample preparation. American Chemical Society
