Thermal inactivation studies on some enzymes from Vibrio marinus, an obligately psychrophilic marine bacterium

Creator:: Mathemeier, Paul Fredrick
Abstract:: Some enzymes of the citric acid cycle and glycolytic pathway in cell-free extracts of Vibrio marinus MP-1 were compared for thermal lability. After one hour of moderate temperature exposure, enzymes of both pathways rapidly lost catalytic activity. For all but one enzyme, 50 percent remaining activity occurred near an averaged...

Concerted actions of ovarian steroids and prostaglandin F₂a on smooth muscle contractility of ovine and bovine uterine arteries

Creator:: Ford, Stephen Paul
Abstract:: The role of estradiol- 17β, progesterone and prostaglandin F₂α (PGF₂α) in altering contractility of uterine vascular smooth muscle was investigated. A segment of uterine artery (3. 5 cm) supplying each uterine horn of ewes and heifers were removed at necropsy and perfused with oxygenated Krebs Henseleit Solution prior to initiating...

An examination of the form and variability of manganese oxide in Columbia River suspended material

Creator:: Covert, Paul Allister
Abstract:: Suspended particulate matter (SPM) in the Columbia River is a mixture of particles of several origins having varying physical and biogeochemical properties. The relative abundances of these freshwater particles changes with season and apparently also with tide. Prior investigation has quantified seasonal variation of organic material in both the Columbia...

Population biology of rare mariposa lilies (Calochortus: Liliaceae) endemic to serpentine soils in southwestern Oregon

Creator:: Fredricks, Nancy Ann
Abstract:: Population dynamics, plant communities, and abiotic environments of three narrowly endemic, allopatric mariposa lilies (Calochortus Pursh) are described and compared. All were restricted to ultramafic soils in southwestern Oregon with high concentrations of nickel, zinc, and chromium, and low calcium to magnesium ratios. Soils inhabited by the three species differed...

Nongenomic action of progesterone inhibits oxytocin signaling through the ovine oxytocin receptor

Creator:: Bishop, Cecily V.
Abstract:: Experiments were conducted to characterize the nongenomic effects of progesterone (P4) on binding of oxytocin (OT) to the ovine oxytocin receptor (OTR) and signal transduction. The dose-response relationship of P4 to OT binding to the OTR in endometrium was examined. Progesterone interfered with the binding of OT to the OTR...

The reaction between O-ions and F centers

Creator:: Staible, Thomas Fredrick
Abstract:: The photochemical reaction between O⁻ ions and F centers was investigated. The activation energy was determined by the Arrhenius law to be 0.10 + 0.04 eV for temperature below 180°K. The diffusion of alpha centers towards the oxide ion was eliminated as the rate limiting step and the low trapping...

The interaction of polylysine with DNA as studied by polarization of flurescence

Creator:: Evett, Jay Fredrick
Abstract:: A fluorescent dye, 1-dimethylaminonaphthalene-5-sulfonyl chloride (dansyl chloride), was covalently bonded to polylysine. The dansyl tagged polylysine was complexed to DNA by gradient dialysis. The polarization and intensity of fluorescence of the dansyl and the turbidity of the complex were measured as a function of salt concentration for a variety of...
