Expression of serotonin, chromogranin-A, serotonin receptor-2B, tryptophan hydroxylase-1, and serotonin reuptake transporter in the small intestine of dogs with inflammatory bowel disease

Creator:: Bailey, Candice
Abstract:: The neuroendocrine system of the gut plays a significant role in regulating intestinal motor and sensory functions, as well as modulating inflammation in the intestine. The intestinal mucosa is the dominant site of serotonin (5HT) synthesis in mammals, with more than 95% of the intestinal 5HT being present in 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...

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...

Conserving avian diversity in agricultural systems : the role of isolated Oregon white oak legacy trees

Creator:: DeMars, Craig A.
Abstract:: Over one third of the earth’s land surface has been modified to some extent for agricultural purposes. The large global footprint of agriculture, combined with the knowledge that existing reserve networks are likely insufficient for long-term conservation of native biodiversity, has necessitated that agricultural systems contribute to conservation of native...

The influence of environmental and physical factors on the thermal patterns of headwater streams

Creator:: Carr, Craig A.
Abstract:: A case study was performed in 2000 and 2001 to characterize the thermal pattern of four morphologically similar eastern Oregon streams and to identify the physical and environmental factors that expressed significant and functionally viable relationships with stream temperature (daily maximum, daily minimum and daily rate of heating). Stream and...

Forests on the Move: Forest Inventories and Wood Anatomy from the Fragmented Forests of Guairá, Paraguarí, and Central, Paraguay

Creator:: Cervantes, Andrew G.
Abstract:: Forest composition in Paraguay has been in a state of change for the past half century due to land management practices, forest fragmentation, and deforestation for agriculture. How these factors affect dendrological diversity and wood anatomy in Paraguay is not well understood. This thesis documents Paraguayan forest composition on the...

Much Ado About Weak Measurement

Creator:: Bauml, Benjamin Noë
Abstract:: I had to write again. My research lay in science, and it was a science of three parts. The first part made a careful, introductory chapter, begged for by things that were lacking. It summarizes the von Neumann measurement model, derived from the Stern-Gerlach experiment, and it explains how weak...

Correlation of fecal ergovaline, lolitrem B, and their metabolites in steers fed endophyte infected perennial ryegrass straw

Creator:: Murty, Lia D.
Abstract:: Perennial ryegrass (PRG, Lolium perenne) is a hardy cool-season grass that is infected with the endophytic fungus Neotyphodium lolii, which enables the plant to be insect repellant and drought resistant, lowering the use of insecticides and fertilizers. However, this fungus produces the compound lolitrem B (LB, m/z 686.4) which causes...

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...
