Growth rate effects during starvation-survival of a marine psychrophilic vibrio

Creator:: Moyer, Craig Lee
Abstract:: Cell populations of the marine bacterium ANT-300, from either batch culture or continuous culture with dilution rates ranging from D = 0.170 h⁻¹ (fast) to D = 0.015 h⁻¹ (slow) were monitored for 98 days under starvation. Viability (CFU), acridine orange direct counts (AODC), and optical density were measured. DNA,...

Zooarchaeologjcal and Taphonomic Investigations of Site 35JA42, Upper Applegate River, Southwestern Oregon

Creator:: Schmitt, Dave N.
Abstract:: Site 35JA42 represents the first protohistoric village complex excavated in Southwest Oregon. Analyses of animal bones recovered from the site offer the first significant insights into human subsistence behaviors in this region. Although the faunal assemblage is extremely fragmented, detailed zooarchaeological analysis indicates that deer were the primary meat resource...

The effect of Blastocystis sp. ST1 on the expression of serotonin transporter,tryptophan hydroxylase, toll-like receptor 2, and toll-like receptor 4 in CACO-2 cellculture

Creator:: Lawrence, Yuri Alexander, 1980-
Abstract:: Blastocystis spp. is a common intestinal parasite in humans and animals that has been associated with acute or chronic digestive disorders such as irritable bowel syndrome. Serotonin mediates intestinal motility, sensation, and secretory function in the normal intestinal tract. Serotonin (5-HT) signaling is decreased in animal models of colitis, as...

Path Sums and Proper Times in Causal Sets

Creator:: Shuman, Samuel A.
Abstract:: In this thesis, we explore a general method for constructing path sums in a discrete spacetime using a jump amplitude matrix. This is accomplished by deriving a composition law that relates jump amplitudes to the propagator. Then properties of causal sets are used to average this relationship over sprinklings. This...

Biotransformation of 2,4,6-trinitrotoluene by ruminal organisms

Creator:: De Lorme, Marthah J. M.
Abstract:: 2,4,6-Trinitrotoluene (TNT) has been the common munitions used in the world and is an environmental contaminant that is amendable to reductive transformation reactions. The rumen is an extremely reductive environment containing diverse microbial populations. There are 21 pure culture ruminal bacteria species in culture collection, these were tested for the...

Bacterial 16S ribosomal DNA analysis of pyrrolizidine alkaloid detoxifying enrichments from the ovine rumen

Creator:: Gray, Diane R.
Abstract:: Bacterial cultures enriched from sheep rumen fluid have demonstrated the ability to detoxify pyrrolizidine alkaloids (seneciphylline and jacobine) in tansy ragwort (Senecio jacobaea). The microbes are difficult to isolate using classical anaerobic techniques, therefore, microbes from two different enrichment cultures demonstrating similar degradation activity were identified using their 16S ribosomal...

Metabolism of toxic plant alkaloids in livestock : comparative studies on the hepatic metabolism of pyrrolizidine alkaloids in sheep and cattle and of ergot alkaloids in an endophyte-resistant mouse model

Creator:: Duringer, Jennifer Marie
Abstract:: The pyrrolizidine alkaloids (PAs) and ergot alkaloids are known natural toxicants found in livestock forage. These alkaloids contribute to large economic losses in livestock throughout the world. An understanding of the mechanisms of toxicity and development of better diagnostic tools for better management practices was investigated. Variability exists in the...

Molecular characterization of bacterial populations implicated inthe anaerobic metabolism of toxic plant alkaloids from two different experimental and environmental sources

Creator:: Rattray, Rogan MacKay
Abstract:: There have been many studies that describe the protective degradation or metabolism of potentially harmful plant toxins, such as, mimosine from Leucaena leuconcephala, pyrrolizidine alkaloids from tansy ragwort (Senecio jacobaea), oxalate and some mycotoxins by rumen microbes. There are many cases of plant-related toxicoses suffered by ruminant animals where there...

Ruminal Biodegradation of Heterocyclic Toxic Compounds

Creator:: Tanaree, Dan D.
Abstract:: Cyclic nitramines are a class of compounds that include most of the commonly used explosives today. These are among the most common toxicants released into the environment as a result of human activity, generated on military ranges, battlefields, and production sites. Of these, hexahydro-1,3,5-trinitro-1,3,5- triazine (RDX) is of particular interest,...

A modeling study on downslope windstorms

Creator:: Smith, Craig M.
Abstract:: The generation mechanism for downslope windstorms was shown to vary according to inversion height and strength using a series of numerical experiments. Strong low level inversions were dominated by interfacial waves on the inversion, while high level inversion and cases without an inversion were dominated by internal gravity wave (IGW)...
