Production Of Monoclonal Antibodies Specific For The Gamonts Of Eimeria Tenella, Nancy Carol Larsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cecal coccidiosis, caused by the protozoan Eimeria tenella, may manifest as a devastating disease in young chickens and result in substantial economic loss for producers. The parasite progresses through a complex life cycle, exhibiting both asexual and sexual (gamont) stages of development. The purpose of this study was to produce a panel of monoclonal antibodies (MoAbs) against epitopes contained on surface antigens (Ags) of the gamonts of E. tenella with the intent of blocking the fertilization process. Gamonts were harvested from infected ceca, partially purified by differential centrifugation throught a discontinuous 5050% Percoll density gradient and used as a …

Factors Affecting The Long-Term Market And Profit Potential Of The Utah Apple Industry, Jodie R. Harris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Utah apple industry is a small competitor in a major market. Efforts were made to analyze the long-term market and profitability potential of the industry. This study consisted of two parts, whole farm simulations and a consumer preference survey.

A whole-farm simulation model (FLIPSIM) was used to evaluate and test variations in price, debt load and sizes of Utah apple production units. These variations examined the effects of various possible market and financial conditions that producers could face given the current situation of the apple industry. FLIPSIM was used to demonstrate the stochastic nature of prices and yields of …

Utilization Of Poultry Waste (Composted Caged-Layer) As A Supplement For Sheep Fed Straw During Late Pregnancy, Raul Meneses R.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The utilization of composed caged-layer waste (CCLW) in diets for pregnant ewes fed cereal straw was evaluated. Five sheep were assigned to five diets containing, 0, 5.72, 11.37, 23.80, and 32.69% CCLW in a 5x5 Latin square design. Water intake, feed intake and feces output were measured. Feed and feces were analyzed for dry matter, crude protein, acid detergent fiber (ADF), neutral detergent fiber (NDF), organic matter, hemicellulose and minerals. Thus, nutrient digestibility and nitrogen balance could be calculated. Forty dry, pregnant ewes in the last third of generation were assigned to four dietary treatments contained 0, 11.25, 22.08 and …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Obesity is a prevalent and refractory disorder. This study consisted of a meta-analysis of research focusing on diet and exercise treatments and their impact on obesity related measures. Only studies that report data for periods of 6 months or more after treatment onset were included. Forty-four studies were analyzed. These were drawn from 16 previous reviews of the literature as well as several computer data bases.

Following are some of the tentative conclusions drawn: (a) diets consisting of improved nutritional quality yield superior results to restricted calorie diets; (b) flexible, self-directed exercise yields better results than more regimented exercise; (c) …

Reducing Stress Of Inservice Teachers, Jeffrey R. Curley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A prototype treatment developed to significantly reduce symptoms of stress among inservice teachers was tested in this experiment. Thirty participants selected for high stress levels were randomly assigned to treatment and control groups. They were assessed on environmental, personality, and emotional variables, using self-report and expert-judge measures, both pre- and posttreatment. The experimental treatment was holistic, incorporating all processes previously found to be related to reducing teacher stress. At posttreatment, the treatment group averaged 1.02 standard deviations lower on the stress measures than the control group. Significant differences in the posttest means, favoring the experimental group, were found for 23 …

Morphological Effects Of Lonidamine On Two Human-Tumor Cell Culture Lines, Joseph G. Szekely, Anya U. Lobreau, Sabine Delaney, G. Peter Raaphorst, Mark Feeley

Scanning Microscopy

Lonidamine, 1-(2-4-dichlorobenzyl)-1-H-indazol-3-carboxylic acid. is an anticancer drug that has its primary action on cellular metabolism rather than cell division. Since lonidamine is not effective in all tumor cells, we have tested it in two human-tumor cell culture lines: MOLT-4, a T-leukemia and U-87 MG. a glioma. Lonidamine exposure of MOLT-4 cells at 50 μg/mL and pH 6.7 disrupted the mitochondria within 1 h of treatment. The mitochondria were swollen and the cristae were disrupted. When the treated cells were re-incubated in fresh medium at pH 7.4 the mitochondria rapidly returned to their normal morphology. The U-87 MG glioma cells did …

Salinity Tolerance In Plantago Species: An Ultrastructural And X-Ray Microanalytical Investigation Of Differences In Ion Transport In The Roots, Diana M. R. Harvey

Scanning Microscopy

Root ultrastructure and elemental distributions in regions 3-4 mm behind the apex were examined by transmission electron microscopy and x-ray microanalysis in Plantago maritima ( grown ± 200 mM NaCl) and Plantago media (grown± 20 mM NaCl). In Plantago media vacuolation was incomplete in the cortical and xylem parenchyma cells. Epidermal transfer cells were observed in plants grown in the presence of NaCl. In Plantago maritima grown in the presence of NaCl, vacuolation was complete. In the xylem parenchyma cells of Plantago maritima controls the mitochondria were clustered adjacent to the vessels, rather than evenly distributed throughout the cytoplasm. X-ray …

Soluble And Insoluble Dietary Fiber In Cooked Common Bean (Phaseolus Vulgaris) Seeds, Joe S. Hughes, Barry G. Swanson

Food Structure

The common bean (Phaseolus vulgaris) requires cooking for extended periods of time prior to consumption. In this investigation both quantitative and microstructural changes in common bean dietary fiber as a result of cooking were examined. Cooking resulted in a slight decrease in soluble dietary fiber and a marked increase in insoluble dietary fiber. The increase in insoluble dietary fiber was responsible for a 15 -30 percent increase in total dietary fiber.

Scanning electron microscopy was used to examine the microstructure of uncooked and cooked bean flours and the insoluble and soluble dietary fiber fractions of these two fl ours. In …

An Electron Microscopic Study Of The Adherence Of Lactobacillus Acidophilus To Human Intestinal Cells In Vitro, S. K. Hood, E. A. Zottola

Food Structure

In this study, transmission electron microscopy was used to visualize the adherence of Lactobacillus acidophilus to human intestinal tissue cells (HITC) in vitro. There appeared to be a layer of electron dense material on the bacterial cell and on the intestinal cell which may mediate adherence. When L. acidophilus attached to intestinal tissue cells after a short contact period, it did not appear to disrupt the integrity of the intestinal cell. Treatment of the bacterium with sodium periodate and concanavalin A reduced the adherence to HITC, suggesting that a carbohydrate was involved. Electron micrographs of periodate-treated cells revealed that the …

Cereal Structure And Its Relationship To Nutritional Quality, S. H. Yiu

Food Structure

Factors that determine the digestibility of carbohydrates and minerals in cereals are examined . Most carbohydrates and minerals in cereals are structurally bound, either surrounded by or associated with cell wall components not easily digested by non-ruminant animals and humans. Treatments such as mechanical grinding and heat improve the digestibility of nutrient s . Further processing and cooking result in structural and physeochemical changes of cereal starch, phytate, and dietary fiber. Such changes greatly Influence the physiological and metabolic effects in animals and humans. The digestive breakdown of most nutrient components is also dependent on the activities of enzymes in …

Effects Of Protein Concentration In Ultrafiltration Milk Retentates And The Type Of Protease Used For Coagulation On The Microstructure Of Resulting Gels, Dragoljub D.J. Gavaric, Marijana Caric, Miloslav Kalab

Food Structure

Milk retentates (35~ total solids, 13~ protein) obtained by ultrafiltration were diluted with the permeate to 3 . 2, 5.0, 6.5, 10.0, and 13.0% protein and coagulated using conrnerc1al proteases. Rennet or one of microbial proteases isolated from Bacillus potymlxa , Endothla parasfttca, Mucor mtehel, or Mucor pusfllus were used . Coagulation times were decreased with the Mucor proteases as the protein concentrations in the retentates were increased but the coagulation times were increased with B. potymlxa and f. parasltlca proteases under similar conditions . Firmness was higher in gels made from homogenized retentates than from nonhomogenized retentates of the …

Fluorescence Microscopy Studies On (1,3) - B-D-Glucan In Barley Endosperm, A. W. Macgregor, G. M. Ballance, L. Dushnicky

Food Structure

Development of (1,3;1,4)-B-D-glucan and (1,3)-B-D-glucan in kernels of Himalaya and Bonanza barley has been followed by fluorescence microscopy using calcofluor and aniline blue fluorochromes. Specific enzymes were used to confirm the identity of these two polysaccharides in sections of endosperm tissue. All barley lines tested contained both types of B-glucan but (1,3;1,4)-B-glucan was synthesized at an earlier stage of development than was (1,3)-BGlucan. Small bead-like deposits of (1,3)-B-glucan were detected in all cultivars examined. These deposits were present throughout the endosperm and appeared to be associated with the inner walls of endosperm cells. After treatment of sections with (1,3)-B-glucanase, these …
