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...

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...

Metabolism of ergot alkaloids by sheep

Creator:: De Lorme, Marthah J. M.
Abstract:: The digestion responses and degradation of ergovaline and production of lysergic acid in the rumen of sheep offered Neotyphodium coenophialum-infected tall fescue straw at two ergovaline levels was investigated. Six crossbred wethers (56 +1- 3 kg BW) were randomly assigned to one of two treatment groups in a cross-over design....

Pre-pliocene structural geology and structural evolution of the northern Los Angeles Basin, southern California

Creator:: Schneider, Craig L.
Abstract:: Detailed subsurface structure contour maps and cross sections have shown the northern Los Angeles basin to be underlain by a south facing monocline that is complicated by secondary faults and folds. The monocline forms a structural shelf that marks the northern boundary of the Los Angeles central trough. The monocline...

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...

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...

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...

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...
