BACKGROUND/AIMS Cholestasis is associated with naloxone reversible antinociception and opiate receptor antagonists are used clinically to treat pruritus. Pain and pruritus are closely interrelated and opioids modulate both sensations. Therefore, we undertook a series of experiments to characterize opioid-mediated antinociception in cholestasis and determine(More)
Pseudomonas aeruginosa frequently acts as an opportunistic pathogen of mucosal surfaces; yet, despite causing aggressive prostatitis in some men, its role as a pathogen in the prostate has not been investigated. Consequently, we developed a Ps. aeruginosa infection model in the rat prostate by instilling wild-type (WT) Ps. aeruginosa strain PAO1 into the(More)
The least significant change (LSC) represents the smallest difference between successive measurements of bone mineral density (BMD) that can be considered to be a real change and not attributable to chance. The LSC is derived from same-day in vivo BMD precision measurements. Our first objective was to determine if the LSC differs between technologists. Our(More)
A new tissue slice preparation of the cuttlefish eye is described that permits patch-clamp recordings to be acquired from intact photoreceptors during stimulation of the retina with controlled light flashes. Whole-cell recordings using this preparation, from the retinas of very young Sepia officinalis demonstrated that the magnitude, latency, and kinetics(More)
Pseudomonas aeruginosa has long been known to produce phenotypic variants during chronic mucosal surface infections. These variants are thought to be generated to ensure bacterial survival against the diverse challenges in the mucosal environment. Studies have begun to elucidate the mechanisms by which these variants emerge in vitro; however, too little(More)
BACKGROUND Nonbacterial prostatitis has no established etiology. We hypothesized that proteinase-activated receptor-1 (PAR1) can play a role in prostatitis. We therefore investigated the effects of PAR1 stimulation in the context of a new model of murine nonbacterial prostatitis. METHODS Using a hapten (ethanol-dinitrobenzene sulfonic acid- (DNBS-))(More)
Electron paramagnetic resonance spectra obtained with a 5-Nitroxylstearate spin label indicate that inhomogeneous lipid domains exist naturally in the bulk lipid matrix of cat synaptic plasma membranes at physiological temperatures, associated with non-cooperative phase transitions spanning broad temperature intervals between about 10 degrees C and 40(More)
Name: Lisa Nelson Title: An Investigation of the Phototransduction Cascade and Temporal Characteristics of the Retina of tlie Cuttlefish, Sepia Officina/is Cephalopods have extremely well developed visual systems which are of particular interest due to the well known morphological similarity of the cephalopod eye to the vertebrate eye. This similarity ends(More)
