For more than 30 years, researchers have investigated the effects of whole body vibration (WBV) platforms on athletic performance. WBV is a modality in which an individual stands on a vibrating platform to obtain performance effects. Frequency and amplitude of the vibration are the commonly adjusted parameters. The use of...
Studies were undertaken to determine the extent and rate of
binding of Hg-203 labeled phenylmercuric acetate and mercuric ace
tate in rat kidney and liver slices and their subcellular fractions
after 37°C incubation of the slices in Krebs-Ringer -phosphate solutions
containing the mercurials at 10⁻⁴ molar. A fast and parallel...
Noise induced hearing loss is a subject of growing
concern. Over the past 15 years, several well-documented
studies have been completed which express the relationships
between industrial noise exposure and damage to normal and
pathological ears. This research has provided knowledge of
considerable importance to developing successful hearing
conservation programs....
Forced vital capacity lung expiration examinations of nonsmoking
and cigarette-smoking male sample populations were compared to
determine if the 75 to 85 percent segment was a more sensitive test
of early lung dysfunction. The nonsmoking population was composed
of 240 men who were tested for values of forced vital capacity...
Quantity variations in pigments and lipid classes were determined
following γ-irradiation of Micrococcus radiodurans, Sarcina
lutea, and Pseudomonas aeruginosa.
Pigmentation was determined by extraction with organic solvents
and measured as optical density at 475 mμ for M. radiodurans
and S. lutea, and 410 mμ for Ps. E aetuginosa. Pigments of...
In three separate trials rats were fed either a basal diet deficient
in selenium and vitamin E or the same diet supplemented with
one or both of these factors. In addition to these treatments in two
of the trials, ethoxyquin was included to provide adequate lipid antioxidant
protection and to...
The DNA repair capabilities of rainbow trout (Salmo gairdneri)
were studied vising the method of autoradiography. Trout were fed a
semi-purified control diet containing 0 ppm, 50 ppm, or 300 ppm
cyclopropenoid fatty acids (CPFA) for 6-9 weeks. Liver slices were
prepared and exposed in vitro to a control treatment,...
The purpose of the study was to compare the visual-motor performance
of college students who reported ingestion of certain drugs with
those college students who reported no drug ingestion. The study
drugs included the following drugs or groups of drugs: tobacco,
alcohol, marijuana, LSD, mescaline, barbiturates, and amphetamines.
A total...
The effect of concentration, vehicle and surfactant on the
absorption of benzocaine -³H across the rat's rectal mucosa was
investigated. Blood radioactivity levels were determined after the
application of benzociane -³H containing suppositories and ointments.
A wet oxidation method was used for sample digestion. Since the
radioactivity counted is the...
