Thymic Peptide Modulates Glutathione Redox Cycle And Antioxidant Enzymes In Macrophages, Choon Sil Park

Loma Linda University Electronic Theses, Dissertations & Projects

The effect of a 6-kDa thymic peptide (TP) on the oxidative burst of a murine macrophage cell line J774 was determined. TP (12.5-200 μg/ml) was incubated with 5 x 10⁵ J774 cells at 37° C and 5% C0₂ for 18 h and oxidative burst was triggered by zymosan; chemiluminescence was amplified by luminol and measured in an automated luminometer. TP exhibited a concentration-dependent inhibition of oxidative burst. To study the mechanisms involved in TP’s inhibition of oxidative burst, its effect on the glutathione (GSH) redox cycle, GSH biosynthesis, and antioxidant enzymes was investigated. TP was shown to increase …

A Non-Human Primate Model For Evaluating A Fenestration Corticotomy Technique, Philip G. M. Khng

Loma Linda University Electronic Theses, Dissertations & Projects

A study model has been designed to evaluate the effectiveness of a new fenestration corticotomy procedure in two non-human primates Macaca fasicularis.

The objective of this study was to evaluate the efficacy of a new conservative corticotomy procedure to facilitate dental translation using fenestrations. This pilot study compared treatment and control quadrants of each individual animal's maxilla and mandible with both having the same retraction appliance and force on the 2nd premolar following extraction of the 1st molars. The null hypothesis stated that there was no significant statistical difference between the new conservative corticotomy procedure (fenestrations) when compared with …

The Effect Of Temperature On The Growth Of The Zebra Mussel, Dreissena Polymorpha (Pallas), Tamara K. Ross '93

Honors Projects

Dreissena polymorpha (Pallas), zebra mussels, are recent invaders of North American freshwater systems. They have a high reproductive rate and settle in high densities which can clog water intake valves and pipes. Many studies investigating the use of heat as a control measure have examined the effects of high temperatures on zebra mussel mortality. Much less is known about the effect of temperature on the actual growth rate and development of zebra mussels. This study examined the growth rates of zebra mussels at 10°C, 20°C, and 25°C over two four-week periods in the laboratory. Mussels were placed in culture dishes …

The Syringomycins: Finding Their Role In Nature, Jon Takemoto

Faculty Honor Lectures

About ten years ago, I began looking for a research problem in the field of plant-microbe interactions. As the name implies, this is the study of how plants and microorganisms associate-either for their mutual benefit or at the expense of one partner. An example is symbiotic nitrogen fixation between leguminous plants and root-colonizing bacteria. Both benefit-the plant gains nitrogen in a useful form and the bacteria gain nutrients and protection. A better understanding of a plant-microbe interaction system could be used to benefit agriculture. For example, boosting nitrogen fixation would mean less petroleum-derived nitrogen fertilizers. These interactive biological systems and …

A Study Of Factors Controlling Physical Properties Of Mozzarella Cheese And The Manufacture Of A Reduced Fat Mozzarella Cheese, Richard Kevin Merrill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Variables affecting the physical properties of Mozzarella cheese were investigated. The effects of various milk-clotting enzymes were examined. The type of milk coagulating enzyme used played a significant role in determining physical properties of direct acid Mozzarella cheese. Cook color was not affected by enzyme type, but melt and stretch were significantly affected.

Proteolytic nature of starter cultures was reviewed and recommendation s were give n. Cheese made with proteinase-deficient strains had more stretch after holding for 14 and 28 d than cheese made with non-deficient strains. Cheese made with pairs or single strains of L. helveticus had the same …

Effects Of Rumen-Protected Amino Acids On Production In Holstein Cows, David Paul Dawson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Six nonlactating Holstein cows fitted with rumen and duodenal cannula were used to determine the efficacy of pH sensitive fatty acid polymer encapsulation as a means protecting amino acids from rumen fermentation and as a post-ruminal amino acid delivery system. The cows were arranged in a 2 X 2 factorial in a Latin Square design. Treatments were 1) the basal ration, and 2) basal ration plus rumen-protected lysine, methionine, and threonine at 10 g each per day.

Rumen parameters measured were pH, ammonia, volatile fatty acids, protozoa, liquid, and dry matter rate of passage, total viable bacteria, and viable cellulolytic …

Influence Of The Ruminant Digestive Process On The Germinability Of Range Forage Species, Mohammed S. Al-Mashikhi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ingestion and dispersal of seeds of desirable species by domestic livestock is potentially important as a range improvement practice, but the passage of seed by livestock has only been studied in a fragmented way, particularly for species adapted to rangelands of western North America. The objectives of this research were to examine the effects of different periods of exposure to in vitro and in vivo digestion processes in cattle on the germinability of several grass species, and determine if the in vitro incubation technique is a good predictor of seed fate following passage through the ruminant digestive tract.

Seeds of …

Effect Of Salinity (Nacl) On Germination, Growth, Ion Accumulation, And Protein Synthesis In Alfalfa (Medicago Sativa L.), Thamir S. Al-Niemi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

To study the effect of NaCl stress on gene expression in alfalfa (Medicago sativa L.), greenhouse and laboratory experiments were conducted with 22 cultivars during germination and post-germination growth. The ability of alfalfa cultivars to germinate at the different NaCl concentrations was not related to their postgermination performance (salt tolerance) under those conditions.

Genetic effects were evident for Na and Cl ion uptake and accumulation in alfalfa shoots and roots. The strategies of alfalfa cultivars to cope with NaCl stress includes exclusion of Na from shoots and Cl from roots or from the whole plant depending on cultivar and …

Postbreeding Ecology Of Adult Male Northern Pintails And Cinnamon Teal Near Great Salt Lake, Utah, Robert R. Cox Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I studied nutrient reserves, digestive organs, molt intensity, diets, and seasonal changes in food resources available to postbreeding adult male Northern Pintails (Anas acuta) and Cinnamon Teal (Anas cyanoptera) in marshes near Great Salt Lake, Utah. Total lipid and protein reserves of Northern Pintails were lower during the flightless period than before or after. For Cinnamon Teal, total protein was lowest during the flightless period, and total lipid showed a similar trend. Total mineral did not differ among plumage classes in either species. Use of nutrient reserves in these species may be an endogenous rhythm in …

Formation Of Polycyclic Aromatic Hydrocarbons On The Surfaces Of Ultra-High Temperature Treated Meat, Michelle T. Foote

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect of ultra-high temperature (UHT) on production of polycyclic aromatic hydrocarbons (PAHs) on the surface of beef steaks was determined. Beef steaks were treated with five treatments, raw, UHT, UHT/grill marks, UHT/grill marks/microwave, and charcoal grilled. Four PAHs, benzo[a]pyrene, benz[a]anthracene, benzo[b]fluoranthene, and benzo[k]fluoranthene, were quantified. High performance liquid chromatography (HPLC) and gas chromatography (GC) were used to purify and analyze the PAH extracts, respectively. Levels of PAH found on charcoal-grilled steaks were higher than those observed in the literature. A balanced incomplete block design was used to analyze the data. There were no significant differences among the treatments in …

Anaerobic Treatment Of Whey Permeate Using Upflow Sludge Blanket Bioreactors, Seokhwan Hwang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Whey permeate was anaerobically digested in laboratory scale upflow anaerobic sludge blanket reactors. Nine hydraulic retention times between 5 and 0.2 days were examined with a fixed influent concentration of 10.6 ± 0.2 g COD/L.

Chemical oxygen demand removal efficiency ranged from 99.0 to 18.9% and maximum production rate of methane gas was 2.67 L/L/day at a hydraulic loading rate of 12.97 kg COD/m³/day. About 70% of the chemical oxygen demand removed was converted to methane.

Both the nonlinear least square method with 95% confidence interval and linear regression were used to evaluate kinetic coefficients. The maximum substrate …

Sensory And Functional Properties Of Wheat Stored Under Home Conditions, Marilyn M. Shumway

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Samples of wheat that had been stored in homes up to 48 years were collected with information about age and storage conditions. Germination, weight per bushel, protein, moisture, grade, and aroma were investigated. Volumes of gluten balls and bread made from ground whole wheat samples were measured. Sensory attributes of bread were evaluated by Quantitative Descriptive Analysis (QDA) for eight flavor and seven texture characteristics. Because of the tremendous variation in samples, generalizations on cause and effect are difficult to make. No one criterion was a perfect indicator of quality. A high percentage of germination was one of the better …

Treatment Of Low Quality Forages By Hydrogen Peroxide And(Or) Anhydrous Ammonia And Their Utilization In Ruminant Nutrition, Mohammed Diouri

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three experiments were conducted to evaluate low quality forages treatment by anhydrous ammonia (NH₃) and(or) hydrogen peroxide (H₂O₂).

In experiment I, a control and three treatments of barley straw were compared: NH₃, NH₃ after rehydration of the straw with water (NH₃+H₂O), and NH₃ after rehydration with a H₂O₂ solution (NH₃+H₂O₂). Forages were fed, with a supplement, at two levels of intake (ad libitum and 75% of ad lib.). Treatments were administered in a split-plot in a Latin …

Longitudinal Study Of Plasma And Erythrocyte Selenium Levels In Type I Diabetic Children During Development And Treatment Of Ketoacidosis, Pi-Hsia Fan

Chemistry & Biochemistry Theses & Dissertations

Most studies on the biological activity of selenium have focused on its role at the active site in the ubiquitous enzyme, glutathione peroxidase (GSH-Px) which catalyzes the removal of hydrogen peroxide and organic hydroperoxides (1). A connection between selenium deficiency and a wide range of diseases in animals and humans has been reviewed (2). Development of various forms of human cancer (3), failure of the immune system (4), as well as some cardiovascular diseases (5) have been reported or suspected to correlate with selenium deficiency. However, the physiological function of selenium in these different diseases is not fully understood, and …
