Hough Receives AFLAC Award

Dr. Colleen Hough , of the National Institute on Aging has received an AFLAC Travel Scholarship Award for outstanding work in cancer research. She is one of 81 members of the American Association for Cancer Research who have received AACR-AFLAC Young Investigator Scholar Awards in the past year. AACR associate members are leading postdoctoral students, physicians-in-training and promising graduate students from around the world, all committed to careers in cancer research. Hough is a postdoctoral fellow at NIA, studying global gene expression patterns in ovarian cancer. She received her Ph.D. in 1997 from the University of California, Irvine, for work on Drosophila tumor suppressor genes.

Tropical Medicine Society Honors Two NIH'ers

NIAID's Dr. Franklin Neva (l) and Dr. Jose Ribeiro recently received awards from the American Society of Tropical Medicine and Hygiene. Neva is chief of the opportunistic parasitic diseases section of the Laboratory of Parasitic Diseases (LPD). He received the 1999 Donald Mackey Medal for outstanding research in tropical medicine. He was honored for his research on Chagas' disease in Brazil, Kala-azar in India, and cutaneous leishmaniasis in Honduras. Recently the main focus of his research has been the intestinal worm Strongyloides stercoralis. He and his colleagues have developed several diagnostic tests for human infections with this parasite. They are investigating the immunologic mechanism(s) for this opportunistic infection in patients with human T-cell lymphotropic virus type I. Ribeiro is chief of the medical entomology section in LPD and received the 1999 Bailey Ashford Medal for distinguished work in tropical medicine. Over the past 20 years his research career has focused on the discovery and characterization of anticlotting, antiplatelet, vasodilatory and immunomodulatory substances found in the saliva of bloodsucking insects and ticks. These molecules aid in the transmission of leishmaniaisis, Lyme disease and some arboviral diseases. These same molecules may be used as targets for vaccine development.
