Organochlorine compounds and aliphatic hydrocarbons in Pacific walrus blubber.

Blubber samples were collected from 8 male and 19 female Pacific walrus (Odobenus rosmarus divergens) taken during a 1991 joint USA/USSR cruise traveling widely through the Bering Sea. Dieldrin was found at a level similar to that reported 10 years earlier; oxychlordane was found at a slightly higher concentration than reported previously (Taylor et aL, 1989). Heptachlor epoxide was detected for the first time and found at a low concentration. An initial testing for alpha-, beta- and gamma-HCH detected concentrations similar to those in other Bering Sea pinnipeds. Mean summation of PCB was 0.45 microg g(-1) wet weight in males and 0.16 microg g(-1) in females; only one sample was > 1 microg g(-1). Traces of aliphatic hydrocarbons were detected in all sampled animals, only pristane (x = 0.48 microg g(-1)) was found in concentrations > 1 microg g(-1). Small sample sizes, a lack of samples from immature animals, and uniformly low concentrations of contaminants precluded meaningful analysis of age-related effects and regional differences.

The academic role of the vice president for health sciences: can a walrus become a unicorn?

The post of vice president for the health sciences was first developed in an attempt to interpret, modulate, and buffer the growing power of the medical school in the university and the different values that have existed there. The job has been greatly transformed over the past 10 years as a consequence of a variety of factors. Now a genuine creative effort applied to the design of the administration of health sciences centers and how they fit into universities is needed. The present modes of organization are not equal to the challenges that must be faced. New designs must be created which will recognize the special place of the health sciences in today's world and yet keep its function within the university frame.

Vibrios on the half shell: what the walrus and the carpenter didn't know.

At least nine Vibrio species have been associated with disease in the United States. Vibrio fluvialis, V. hollisae, V. mimicus, and V. parahaemolyticus cause diarrheal diseases, but may also be encountered in extraintestinal infections such as wound and ear infections, septicemia, and cholecystitis. Vibrio alginolyticus, V. damsela, V. metschnikovii, and V. vulnificus primarily cause extraintestinal disease. Toxigenic V. cholerae O1 is the cause of epidemic cholera, whereas nontoxigenic V. cholerae O1 and non-O1 V. cholerae have been associated with both diarrheal and extraintestinal diseases. Most reports of vibrio infections have come from states along the Atlantic Ocean and Gulf of Mexico and from Hawaii, and most of the infections have occurred during summer and fall. Wound and ear infections have occurred after exposure to salty or brackish water or to drippings from raw seafoods. Foodborne vibrio infections are almost all caused by seafoods, especially oysters eaten raw. Thorough cooking and careful handling will render seafoods safe for consumption.
