The location of the translational termination codon for the transmembrane protein (TMP) varies in three infectious molecular clones of simian immunodeficiency virus from macaques (SIVmac). The SIVmac251 and SIVmac142 infectious clones have premature stop signals that differ in location by one codon; transfection of these DNAs into human HUT-78 cells yielded virus with a truncated TMP (28 to 30 kilodaltons [kDa]). The SIVmac239 infectious clone does not have a premature stop codon in its TMP-coding region. Transfection of HUT-78 cells with this clone initially yielded virus with a full-length TMP (41 kDa). …
Psychophysiological Assessment Of Panic Disorder, Kent A. Koehn
Psychophysiological Assessment Of Panic Disorder, Kent A. Koehn
Masters Theses
This study compared physiological and psychological measures between 9 subjects meeting the DSM-III-R criteria for panic disorder (PD) and 9 control subjects to identify psychophysiological differences that might be relevant to the etiology and maintenance of panic attacks. The subjects were assessed through a number of self-report measures and across three laboratory sessions involving five experimental conditions: baseline, role play, relaxation, mental arithmetic, and cold pressor. We measured electrodermal (EDG) and electro-myographic activity (EMG), heart rate (HR), and blood volume pulse (BVP) in terms of absolute values, reactivity, and habituation. Both groups were also assessed in their ability to accurately …

K transport across guinea pig (Cavia porcellus) distal colon was measured in vitro using isotopically determined unidirectional fluxes. Aldosterone stimulated electrogenic Na absorption, as measured by amiloride-sensitive short-circuit current (Isc), and reduced net K absorption from +2.5 ± 0.2 µEq/cm2 per hr to +0.8 ± 0.3 µEq/cm2 per hr (mean ± SEM). Amiloride addition to the mucosal solution did not enhance net K absorption, as expected if inhibiting active Na absorption would reduce active K secretion as in the distal nephron. The amiloride-insensitive Isc was -1.0 ± 0.2 µEq/cm2 per hr (mean ± SEM) …
