School of Medical and Biological Sciences Faculty Publications and Presentations

Upon sulfonation, carcinogenic hydroxyarylamines such as N-hydroxy-2-acetylaminofluorene (N-OH-2AAF) can be further activated to form ultimate carcinogens in vivo. Previous studies have shown that a SULT1C1 sulfotransferase is primarily responsible for the sulfonation of N-OH-2AAF in rat liver. In the present study, two novel human sulfotransferases shown to be members of the SULT1C sulfotransferase subfamily based on sequence analysis have been cloned, expressed, and characterized. Comparisons of the deduced amino acid sequence encoded by the human SULT1C sulfotransferase cDNA 1 reveal 63.7, 61.6, and 85.1% identity to the amino acid sequences of rat SULT1C1 sulfotransferase, mouse SULT1C1 sulfotransferase, and rabbit SULT1C …

How Pigs' Blood Could Save Lives: Canadian Study Could End Need For Human Donations, Allison Hanes, Randy Boswell

Data and Test Instruments

Dr. [Vivian McAlister] agrees that the risk of inter-species infection remains a key obstacle to producing safe pigblood products for people: "The most important thing is that the safety of this sort of thing has to be thoroughly assessed before any implementation. We're dealing more with the immunological barriers, not the infectious disease," he says of his research. "However, if the infectious risks were overcome, or they were understood, an animal source for blood donation" could revolutionize blood-supply services around the world, he says. Currently mired in a depressed pork market that is threatening to put many producers out of …


Regeneration Of Hair Cell Epithelia In The Chick And Salamander, Kenneth Detwiler Dec 1998

Regeneration Of Hair Cell Epithelia In The Chick And Salamander, Kenneth Detwiler

Masters Theses & Specialist Projects

The acousticolateralis sensory system is characterized by a specific receptor cell type called the sensory hair cell and is found in all vertebrates. There are two types of hair cell sensory epithelia based on location: those of the inner ear, such as the organs for hearing and balance, and the lateral line system located within the epidermis. In mammals, including humans, loss or damage of the hair cells of the auditorysystem results in permanent hearing loss. However, this is not the case with birds and amphibians. Amphibians, with a lateral line system, are capable of replacing lost or damaged hair …

Morphine-Conditioned Changes In Locomotor Activity: Role Of The Conditioned Stimulus, Rick A. Bevins, Michael T. Bardo Dec 1998

Morphine-Conditioned Changes In Locomotor Activity: Role Of The Conditioned Stimulus, Rick A. Bevins, Michael T. Bardo

Department of Psychology: Faculty Publications

When a multisensory environment was reliably paired with morphine (2 mg/kg) in rats, that environment, in a drug-free test, evoked a hyperactive conditioned response (CR). When an olfactory cue (banana odor) was the only stimulus element reliably paired with morphine, it also elicited a hyperactive CR. However, a gustatory cue (saccharin solution) evoked a hypoactive CR. This taste-elicited decrease in activity was dose dependent; morphine at 2 and 4 mg/kg conditioned hypoactivity, whereas a higher dose (8 mg/kg) did not. A robust conditioned saccharin aversion occurred only at the highest dose of morphine, suggesting disassociation between the hypoactive CR and …
