Two experiments were conducted to assess the effects of paralysis and oligohydramnios on the development of the rat fetus. Behavior was suppressed in utero by subcutaneous injections of curare or puncture of the amniotic membrane leading to oligohydramnios. In Experiment 1, fetuses were treated with curare, oligohydramnios, both, or a...
A sucrose density-gradient ultracentrifugation technique for
obtaining microsomes has been developed. This technique has
advantages over the classic differential centrifugation technique, in
that it is faster, is better suited to work with small quantities of
tissue, and offers the opportunity to work with a defined microsomal
sub-cellular fraction, rather than...
The induction of drug-metabolizing enzymes is a
complex biochemical process manifested not only by
increases in various cytochrome P-450 isozymes and
related activities, but also by alterations in
endoplasmic reticulum membranes. Little work has been
done to examine how cytochrome P-450 inducing agents
influence other cellular processes, such as
phospholipid...
Cheddar cheese making from ultrafiltered (UF) concentrated milk
potentially increases yield, saves raw materials, cuts transportation costs,
minimizes waste pollution, and stream-lines production. However, the resulting
UF-cheese has been found to differ from conventionally made cheese (CM-cheese)
in its casein matrix and ripening process.
UF and CM Cheddar cheeses were...
Commercially bottled, vitamin C-fortified, cranberry
juice cocktail and cranberry-apple (cranapple) juice
drinks were stored at 5°C under simulated home-use
conditions. Ascorbic acid (AA) and dehydroascorbic acid
(DHA) levels were evaluated over a period of seven days by
high performance liquid chromatography (HPLC). Total
vitamin C content was also determined by...
DNA polymerase gamma has been purified over 67,500-fold from human trophoblast tissue. Purification was achieved through successive chromatographies on phosphocellulose, DEAE-cellulose, DNA-cellulose, and high pressure gel exclusion through Fractogel TSK HW55. This preparation yielded a specific activity of 81 units/mg of protein using the preferred template-primer, poly (A)-oligo (dT)₁₂₋₁₃. Analysis...
The purposes of this study were to construct a Likert scale to
measure the attitudes of individuals toward their personal health, then
to establish the reliability and validity of the scale.
A 22 item scale was developed from computer part whole analysis
of 100 random items written and edited by...
Purpose: The general problem was to determine the relationship between biorhythms and injuries to college football participants representing Oregon State University. Procedures: The population consisted of one hundred and ninty two football players representing Oregon State University who participated in the intercollegiate football seasons of 1981 and 1982. Injury data...
Paraquat (1,11-dimethy1-4,4'-bipyridinium ion) and glyphosate [N (phosphonomethyl)glycine] are herbicides utilized for chemical seedbed preparation in the establishment of grass and legume seed crops. When these herbicides are applied after seeding the crop, seeds which are not protected by a layer of soil could be exposed to the herbicide. Effects of...
