The development of Phytophthora cactorum as a model system for the study of sterol metabolism

Creator:: Gonzales, Robert A.
Abstract:: Phytophthora cactorum lacks sterol synthesis capability. Nevertheless, it exhibits vegetative growth in the total absence of sterol. Supplementation of the growth medium with sterol, however, resulted in a three-fold increase in cell yield. This increase was shown by whole cell and cell free experiments to be the consequence of altered...

Physiological, biochemical, and genetic studies on the [delta]²⁴ sterol methyltransferase of Saccharomyces cerevisiae

Creator:: McCammon, Mark Thomas
Abstract:: The role of the yeast S-adenosylmethionine: Δ²⁴-sterol-C-methyltransferase (SCMT) in sterol metabolism was investigated. Structural analogs of S-adenosylhomocysteine were tested for inhibition of the SCMT enzyme. A wide inhibitory range by these compounds was observed, indicating which structural features of the parent compound are important for binding to the enzyme. The...

Sterol assimilation by Saccharomyces cerevisiae

Creator:: Lewis, Thomas A.
Abstract:: Sterols of the yeast Saccharomyces cerevisiae are found in membranes with a free C-3,β hydroxyl group or stored in lipid droplets as esters of long-chain fatty acids. We have examined the distribution of cholesterol into free sterol and steryl ester pools of a sterol auxotrophic strain of Saccharomyces cerevisiae. Varying...

Hepatotoxicity of monochlorobenzene in rats and rainbow trout

Creator:: Dalich, George M.
Abstract:: The hepatotoxicity of CB was studied in the Sprague-Dawley rat and rainbow trout. In rats, an ip dosage of 9.8 mmol/kg CB (~̲ LD10) produced evidence of liver toxicity over a 72 hr time course. Sulfobromophthalein (BSP) retention maximized 3-16 hr post treatment and normalized after 72 hr whereas plasma...

Measuring and modeling solids movement in a large, cold fluidized-bed test facility

Creator:: Daous, Muhammad A.
Abstract:: Solids movement in large-particle fluidized beds was studied in an 18 in x 18 in (46 cm x 46 cm) tube-filled, cold fluidized bed test facility. Direct measurement of local solid mass flux in two dimensions at various locations inside the bed was made possible by a new instrument developed...

Ecology of harlequin ducks in Prince William Sound, Alaska, during summer

Creator:: Dzinbal, Kenneth A.
Abstract:: Harlequin ducks (Histrionicus histrionicus) were observed during the summers of 1979 and 1980 in Sawmill Bay, northeast Prince William Sound, Alaska. Harlequins were associated with a short, medium gradient, non-glacial stream (Stellar Creek) also used by salmon. Although harlequins nested along Stellar Creek, they apparently did not establish home ranges...

The Development of Astronomy in the United States Prior to 1900

Creator:: Harburg, William A.
Abstract:: From the earliest English colonization to the present day, there has been interest in astronomy in this country. The purpose of this thesis is to show how the science of astronomy developed in America from the earliest observations by educated colonists using imported instruments and publishing in European journals, to...

Small mammal micro- and macrohabitat selection in streamside ecosystems

Creator:: Doyle, Arlene T.
Abstract:: During summer and fall of 1981 to 1983, mark-recapture was conducted in riparian and upland habitats within old-growth and mature forests in the Cascade Range of Oregon. Number of individuals and species richness were greater in riparian than upland habitat. For most species, the mean adult weights and the percentages...
