Senecio jacobaea (tansy ragwort) is a common weed in the
Pacific Northwest that contains toxic pyrrolizidine alkaloids
(PAs). Jacobine, the major PA in Senecio jacobaea, was incubated
with rat liver microsomes and metabolites were isolated by high
performance liquid chromatography (HPLC) and identified by mass
spectrometric analysis. Metabolites included a...
Whole blood selenium levels were measured in 207 horses, representing 41 ranches and 11 regions throughout Oregon. Age, sex,
diet, and history of disease were recorded. Diet was divided into
three categories; local feed only, commercial feed, and Se supplemented feed. Region (p<.01), diet type (p<.01), and a region x...
The purpose of this study was to monitor coronary responses
occurring in the S-T segment of an electrocardiogram before, during
and after exercise following a "standard" carbohydrate-loading schedule with varied vitamin B-6 supplementation. The study was conducted
using four college-aged males who had been training a minimum of two
years...
Cytokinin oxidase activity in callus tissues of
Phaseolus vulgaris L. cv. Great Northern has been examined
using an assay based on the oxidation of radioactively
labeled N⁶ -(Δ² -isopentenyl) adenine (i⁶Ade) to adenine
(Ade). Conditions for the quantitative extraction and
assay of the enzyme have been established. The substrate
specificity...
A kinetics-based enzyme-linked immunosorbent assay (KELA) for detection of serum IgG antibody against bovine respiratory syncytial virus (BRSV) was developed and optimized. Optimization factors tested included brand of microELISA plate, length of incubation periods at various temperatures, type of conjugate, purified versus precipitated antigen preparations, type of dilution buffer as...
Right cerebral hemispheric lateralization for spatial
perception has been reported by using visual and tactile
spatial tasks in brain-damaged patients, split-brain
patients, and normal subjects. The main purpose of the
present study was to investigate whether or not kinesthetic
spatial perception was dominantly processed with the right
cerebral hemisphere as...
The purpose of this study was to determine the
effect of immediate prior meditation (transcendental
meditation) and relaxation upon the pattern of physiological
response and performance of a fine motor and
gross motor task. A second purpose of this study was
to determine whether the long term regular practice of...
