Recent studies have demonstrated that perturbations of
intracellular thiol and calcium homeostasis may be important events
in the early development of cell injury by toxic chemicals.
Incubation of isolated rat hepatocytes in a calcium free
medium, severely depleted intracellular Ca²⁺ levels and resulted in
the loss of both cytosolic and...
Real ear measurements are being used to predict
and validate hearing aid fittings. The purpose of
this study was to investigate the relationship between
the hearing aid response as measured by real ear
measurements to pure tone hearing thresholds and ear
canal resonance. In order to test this hypothesis
clinically,...
Lipid peroxidation is believed to be an important
process in the development of cellular injury. In
addition to the degradation of biological membranes,
increasing evidence indicates that lipid peroxidation can
alter the structure and function of DMA.
The present study examines the peroxidation of
nuclear membranes and the capacity of...
Metabolic and performance parameters of beef calves were
compared between Se supplemented (Se) and control (C) dam
treatment groups from known Se deficient cattle. Four
trials were conducted at three locations involving 50,
36, 25 and 39 experimental dam/calf pairs. Se
supplementation was either two 30 gram oral boluses (90%...
The objective of this study was to determine the effects of processing on sodium - potassium and calcium - phosphorus ratios in tuna canned in oil and in water, peanut butter, white and whole wheat flours. Mineral levels were determined by atomic absorption spectrophotometry in food samples at various stages...
PART I. The concentration of nickel in some soils may be
insufficient to meet the requirements of enzymes such as
urease in soybeans and hydrogenase in Rhizobium. Nickel
availability in soils was examined by measuring microbial
urease activity in soils which were treated with glucose
and urea. Supplemental nickel was...
Perturbed angular correlation (PAC) spectroscopy of dilute zirconia alloys
and YBa₂Cu₃0₇₋x, ceramic superconductors at elevated temperature have been
measured using ¹¹¹Cd as the probe.
The oxygen vacancy concentration in the zirconia samples was controlled by
doping with yttrium or indium, which introduce vacancies, or with niobium, which
removes vacancies. A...
