Influences Of Environmental Education Programs On The Participant's Affinity For Nature, Justin Alan Schmillen
Master's Theses
This study was conducted to determine the change, and the factors influencing the change, in the participant’s affinity for nature resulting from an environmental education experience. In addition, this study also examined the change and factors of change in aspects of the participant’s affinity for nature that directly relate to marine and coastal resources and environments. An adapted version of the Affinity for Nature scale, an outcome measuring instrument used by the American Camp Association was used to collect data from participants (n=529) at Rancho El Chorro Outdoor School and Camp Ocean Pines, whose experience included an overnight component and …
Effects Of Nitrogen And Potassium Fertilizer On Willamette Spider Mite (Eotetranychus Willamettei) (Acari: Tetranychidae), Whitney Ann Geddes
Effects Of Nitrogen And Potassium Fertilizer On Willamette Spider Mite (Eotetranychus Willamettei) (Acari: Tetranychidae), Whitney Ann Geddes
Master's Theses
The spider mite family (Tetranychidae) is a well known pest group in agriculture. Within this family, Willamette spider mite (Eotetranychus willamettei) causes physical harm and potential damage to grapevines (Vitis vinifera) along the central and north coast of California as well as Washington and Oregon. Willamette spider mite prefers cooler climates and feeds by puncturing the plant leaf tissue; therefore removing plant nutrients in the early stages of plant growth. Amending soils with fertilizer is a common cultural practice used in commercial vineyards, but no study has documented the interaction between the effects fertilizer concentrations have on Willamette spider mite. …
Growth Hormone Alters Components Related To Differentiation, Metabolism And Milk Synthesis And Secretion In Mac-T Cells, Tasha Lynn Johnson
Growth Hormone Alters Components Related To Differentiation, Metabolism And Milk Synthesis And Secretion In Mac-T Cells, Tasha Lynn Johnson
Master's Theses
The mammary alveolar cell-T (MAC-T) cell line is able to uniformly differentiate and secrete casein proteins in response to dexamethasone, insulin and prolactin and is extensively used to study bovine mammary epithelial cell function. Growth hormone (GH) has been shown to increase milk protein synthesis both in vivo and in mammary cell models, and induce cytoskeletal rearrangement in 3T3 fibroblast cell line and a Chinese hamster ovary (CHO) cell line. Few studies have focused on identifying the mechanisms involved in differentiated MAC-T cells’ response to GH. We tested the hypothesis that MAC-T cells would respond directly to GH and that …

Platform Effects On Optical Variability And Prediction Of Underwater Visibility, Grace Chang, Michael S. Twardowski, Yu You, Mark A. Moline, Peng-Wang Zhai, Scott Freeman, Matthew Slivkoff, Francesco Nencioli, George W. Kattawar
Biological Sciences
We present hydrographic and optical data collected concurrently from two different platforms, the R/P FLoating Instrument Platform and the R/V Kilo Moana, located about 2km apart in the Santa Barbara Channel in California. We show that optical variability between the two platforms was due primarily to platform effects, specifically the breakdown of stratification from mixing by the hull of R/P FLIP. Modeled underwater radiance distribution differed by as much as 50% between the two platforms during stratified conditions. We determine that the observed optical variability resulted in up to 57% differences in predicted horizontal visibility of a black target.

Growth Hormone Alters Lipid Composition And Increases The Abundance Of Casein And Lactalbumin Mrna In The Mac-T Cell Line, Tasha L. Johnson, Brent A. S. Fujimoto, Rafael Jiménez-Flores, Daniel G. Peterson
Growth Hormone Alters Lipid Composition And Increases The Abundance Of Casein And Lactalbumin Mrna In The Mac-T Cell Line, Tasha L. Johnson, Brent A. S. Fujimoto, Rafael Jiménez-Flores, Daniel G. Peterson
Dairy Science
The MAC-T cell line has been used extensively to investigate bovine mammary epithelial cell function. A lactogenic phenotype is generally induced in this cell line by a combination of dexamethasone, insulin and prolactin and has typically been assessed by milk protein production. Few studies have focused on identifying other factors that may affect milk protein synthesis in the MAC-T cell line, and none have considered the lipid class distribution of MAC-T cells as a component of the lactogenic phenotype. Growth hormone (GH) has been shown to increase milk protein synthesis both in vivo and in mammary cell models, and has …
Lipid Rafts In The Bovine Milk Fat Globule Membrane Revealed By The Lateral Segregation Of Phospholipids And Heterogeneous Distribution Of Glycoproteins, Christelle Lopez, Marie-Noëlle Madec, Rafael Jiménez-Flores
Lipid Rafts In The Bovine Milk Fat Globule Membrane Revealed By The Lateral Segregation Of Phospholipids And Heterogeneous Distribution Of Glycoproteins, Christelle Lopez, Marie-Noëlle Madec, Rafael Jiménez-Flores
Dairy Science
This study reveals the lateral organisation of the milk fat globule membrane (MFGM). Using confocal laser scanning microscopy (CLSM) and a lipid soluble molecule, an exogenous phospholipid and two lectins as fluorescent probes we located triacylglycerols in the core of fat globules and investigated the organisation of the polar lipids and glycoproteins of the MFGM, in situ in milk. Lipid rafts corresponding to the lateral segregation of sphingolipids in liquid-ordered phases surrounded by liquid-disordered domains composed by the glycerophospholipids were observed in the MFGM. These lipid rafts which correspond to rigid sphingolipid-rich domains have a circular shape at room temperature. …
Investigation Of High Salt Intake And Adipogenesis In Rats, May Yong
Investigation Of High Salt Intake And Adipogenesis In Rats, May Yong
Biological Sciences
Sodium chloride has been scrutinized of late, not only for its liberal use as a food preservative but for its contribution to disease states. The causal role of habitual high salt intake in increasing blood pressure and exacerbating hypertension has been established. A growing body of evidence strongly suggests that hypertension contributes to other conditions such as cardiovascular disease, obesity, stroke, and type II diabetes. Rates of hypertension are significantly higher in obese individuals. These comorbidities have been positively associated with the modern Western diet. Worldwide, many government and health organizations have called for public policy measures to mandate sodium …
Overexpression And Partial Purification Of Recombinant Human Serine Hydroxymethyltransferase: A Potential Anticancer Target, Suprit Singh Deol
Overexpression And Partial Purification Of Recombinant Human Serine Hydroxymethyltransferase: A Potential Anticancer Target, Suprit Singh Deol
Chemistry and Biochemistry
Serine Hydroxymethyltransferase (SHMT) is a member of the thymidylate synthase cycle that provides pyrimidine nucleotides to actively dividing cells, including cancer cells. The other two enzymes involved in this cycle have been targets for clinical anticancer drugs, suggesting that inhibitors of SHMT may also be used as clinical anticancer drugs. In order to test potential inhibitors against SHMT, human SHMT has been overexpressed in E. coli and partially purified by selective ammonium sulfate fractionation followed by anion-exchange fast protein liquid chromatography. A coupled assay using L-allo-threonine and alcohol dehydrogenase was used to identify active fractions, which were analyzed …
Correlated Evolution Of Defensive And Nutritional Traits In Native And Non-Native Plants, Nicole Molinari, Charles A. Knight
Correlated Evolution Of Defensive And Nutritional Traits In Native And Non-Native Plants, Nicole Molinari, Charles A. Knight
Biological Sciences
We performed a comparative analysis of defensive and nutritional plant traits responsible for differential herbivory in a series of experimental feeding trials with generalist herbivores. We measured three defensive traits (leaf strength, leaf mass per unit area and endophytic fungal infection) and two nutritional traits (foliar nitrogen and water) for 26 native and eight non-native plant species from coastal California shrublands. Our feeding trials involved three species of generalist herbivore (beet armyworm, cabbage looper and the garden snail) in two types of laboratory feeding trial (single plant species and preference tests). All traits were significantly related to the amount of …
The Relationship Between Plasma Steroid Hormone Concentrations And The Reproductive Cycle In The Northern Pacific Rattlesnake, Crotalus Oreganus, Craig M. Lind, Jerry F. Husak, Cas Eikenaar, Ignacio T. Moore, Emily N. Taylor
The Relationship Between Plasma Steroid Hormone Concentrations And The Reproductive Cycle In The Northern Pacific Rattlesnake, Crotalus Oreganus, Craig M. Lind, Jerry F. Husak, Cas Eikenaar, Ignacio T. Moore, Emily N. Taylor
Biological Sciences
We describe the reproductive cycle of Northern Pacific rattlesnakes (Crotalus oreganus) by quantifying steroid hormone concentrations and observing reproductive behaviors in free-ranging individuals. Additionally, we examined reproductive tissues from museum specimens. Plasma steroid hormone concentrations were quantified for both male and female snakes throughout the active season (March–October). We measured testosterone (T), 5α-dihydrotestosterone (DHT), and corticosterone (B) concentrations in both sexes and 17β-estradiol (E2) and progesterone (P) in females only. We observed reproductive behaviors (e.g., consortship, courtship, and copulation) in the field and measured testis and follicle size in male and female snakes from museum collections to relate …

Development Of A Novel Plasmid-Based Gene Integration System For Lactobacillus Reuteri For The Persistent Treatment Of Celiac Disease, Jeremy Keith Labarge
Development Of A Novel Plasmid-Based Gene Integration System For Lactobacillus Reuteri For The Persistent Treatment Of Celiac Disease, Jeremy Keith Labarge
Master's Theses
Celiac disease (CD) is an autoimmune disorder that affects approximately 1% of the population [55]. CD is characterized by intestinal villus atrophy after consumption of gluten from wheat, barley, or rye. Patients with CD often experience abdominal pain, diarrhea, malnutrition, fatigue, and a failure to thrive. There is currently no treatment for CD. Patients must live on a strict lifelong exclusion of dietary gluten. Due to the high content of gluten in western diets and poor labeling of gluten content, adherence to a gluten free diet (GFD) is difficult [15].Nearly all the enzymes that can digest the gluten peptide are …

The Effect Of Recombinant Human Bone Morphogenetic Protein-2 On The Osseointegration Of Temporary Anchorage Devices, Eden E. Cruz
The Effect Of Recombinant Human Bone Morphogenetic Protein-2 On The Osseointegration Of Temporary Anchorage Devices, Eden E. Cruz
Master's Theses
Titanium has been widely used for dental implants, and in particular, roughened titanium surfaces have provided a means for increasing bone apposition and strengthening the implant-to-bone interface. Finding a way to further increase osseointegration is important because there is a significant clinical benefit to patients if a stable anchor can be established instead of anchoring orthodontic hardware to the molars. In this study, the effect of recombinant human bone morphogenetic protein-2 (rhBMP-2) on the ability of temporary anchorage devices (TADs) to osseointegrate was investigated. The temporary anchorage devices (TADs) used in this study were manufactured from commercially pure titanium and …
