Genetic Over-Expression Of Cytokeratin 18 In Bovine Luteal Cells: Effects On Intermediate Filament Formation And Fas Ligand-Induced Apoptosis, Jennifer J. Forcina

Master's Theses and Capstones

The receptor Fas and its ligand, FasL, are implicated in apoptosis of luteal cells during regression of the corpus luteum (CL). In some cell types, cytokeratin (CK) 8/18 filaments impair FasL-induced apoptosis. Here, we determined if genetic over-expression of CK18 filaments in luteal cells similarly prevents FasL-induced apoptosis. Luteal cell cultures were prepared from early and late stage bovine CL (day 5 and days 16-18 post-ovulation, respectively). The cells were transduced with media, mock vector containing GFP, or a CK18-containing vector, and then exposed to a cytokine cocktail containing FasL for 24 hours. Transduction of luteal cells with CK18 vector …

Evaluation Of Competition Between Turfgrass And Trees In The Landscape, Christopher A. Hendrickson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Population growth in regions of the Intermountain West has resulted in rapid growth of residential neighborhoods. In Utah, the landscapes associated with these expanding neighborhoods consume vast quantities of treated water. This is a concern in all states of the Intermountain West, as water becomes increasingly scarce. Traditionally used turfgrasses, trees and other plants in Intermountain West landscapes require significant amounts of supplemental water considering the intense sunlight, dry winds and sparse rainfall typical of the region. Characterizing the interactions between turfgrass and tree species in these landscapes can aid in the identification of candidate species that consume less nutritional …

Synthesis And Characterization Of Lactose-Amines With Respect To Oil-In-Water Emulsion Stability, Nidhi Garg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fatty amines (hexadecyl-amine) can be esterified to lactose via Schiff-base formation at temperatures of 60° C. Extending the time of the reaction results in a darker colored product due to the Maillard reaction. Due to the amphiphilic properties of the lactose-amines, the emulsion stabilization characteristics were investigated.

In this study, synthesis of lactose-amines was done at four different heating and cooling cycles from 4 to 24 hours. Lactose-amines processed for 24 hours and 12 hours of constant heating and cooling cycles are named as 24H and 12H, respectively. Lactose-amines 4H and 8H were processed for 4 and 8 hours of …

Self-Medicative Behavior Of Sheep Experiencing Gastrointestinal Nematode Infections And The Postingestive Effects Of Tannin, Larry D. Lisonbee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Diet selection and self-medication are fundamental to the survival of all species. The abilities to choose healthy foods in response to past consequences are basic elements of evolution. This study explores self-medication regarding tannins both as a medication and as a dietary challenge. In the first study, sheep with natural parasite infections were offered a low quality supplement containing a dose of tannins considered to be therapeutic (medicine), while the control infected lambs received the same supplement without tannins (placebo). This study included a group of parasite-free lambs. The parasitized lambs ate more of the tannin containing supplement than non-parasitized …

Influence Of Supplemental Legumes That Contain Tannins And Saponins On Intake And Diet Digestibility In Sheep Fed Grasses That Contain Alkaloids, Jacob Michael Owens

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

My objectives were to determine if nutritional benefits occur when animals are offered foods with compounds -- alkaloids, saponins, and tannins - that are potentially complementary. I hypothesized that food intake and digestibility increase when lambs consume plants such as alfalfa ALF that contain saponins or birdsfoot trefoil (BFT) that contain tannins when the basal diet is endophyte-infected tall fescue (TF) or reed canarygrass (RCG) both of which contain alkaloids. I predicted that the nutritional status of lambs would be enhanced if basal diets of alkaloid-containing grasses were supplemented with ALF or BFT.

Lambs fed a basal diet of either …

Enhancing The Proportions Of Healthy Fatty Acids In Milk From Dairy Cows, Korie A.S. Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Twenty cows were used in a repeated measures, block design experiment for 9 wk to determine the effects of feeding partially ruminally inert calcium salts (Ca-salts) of fish oil (FO) and a general fatty acid (FA) supplement (EnerGII) at varying levels. The effects on cow health, milk components, composition of milk FA, and sensory evaluation of milk were evaluated. Cows in the 4 treatments were fed either a control diet of 57% forage and 43% concentrate mix with EnerGII fat supplement at 1.65% of diet DM (CTL) or EnerGII in basal diet was partially replaced with (a) 0.21% …

Mechanisms Of Nutrition Bar Hardening: Effect Of Hydrolyzed Whey Protein And Carbohydrate Source, Shaun P. Adams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The influence of increasing hydrolyzed protein content on the microstructure and hardness of high protein nutrition bars was investigated to determine the mechanism of hardening during storage. Bars with various hydrolyzed protein levels were manufactured using differing ratios of 0, 25, 50, 75, 100% (wt. /wt.) of partially hydrolyzed whey protein isolate (HWPI) to an intact (non-hydrolyzed) whey protein isolate (WPI) which made up approximately 38% of the total bar composition. High fructose corn syrup (HFCS) (42%) and vegetable shortening (20%) constituted the rest of the ingredients. Accelerated aging was performed by storing bars at 32 ^oC for 36 …

Agroforestry Practice Adoption Among Solomon Island Women On The Island Of Malaita, Etta K. Sechrest

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The goal of agricultural training is the adoption and diffusion of introduced agriculture techniques. New subsistence agricultural techniques have been introduced mainly to the male population in many developing countries, even though most subsistence farmers are women. Therefore, an understanding of how new subsistence agricultural techniques can be introduced and adopted by women would be important to achieve. This study focuses on women's adoption of agricultural techniques. It takes place on the island of Malaita, in the Solomon Islands. The study looks at the adoption of agroforestry and several other subsistence techniques that were introduced under a joint program by …

Agriculture And Ecosystem Services: Strategies For State And Local Governments, J.B. Ruhl

Vanderbilt Law School Faculty Publications

Agriculture has long been the Rubik's Cube of environmental policy. Although agriculture is a leading cause of pollution and other environmental harms, it has been resistant to regulation and remarkably successful at requiring payment to do the right thing. This article focuses on hints of movement in a new direction for agriculture, arising out of a merger between the age-old practice of paying farmers to do what is right, the fear of losing agricultural lands to suburban development, the rising fiscal burdens to state and local jurisdictions presented by new suburban development, and the new understanding that farms may hold …

Focused on improving the markets and economic stability of farmers, while also improving the quality of foods available to students, the project implemented the first annual “Massachusetts Harvest for Students Week” during the week of September 24, 2007. As part of Harvest Week, selected schools in Massachusetts purchased and served foods grown and made by local farmers. Marketing materials were used in the participating school cafeterias, and classroom education regarding local agriculture, nutrition, and sustainability was provided. Harvest Week had the potential to improve …

Disestablishing "The Last Plantation": The Need For Accountability In The United States Department Of Agriculture, Seth L. Ellis

Journal of Food Law & Policy

The United States Department of Agriculture (USDA) was signed into law by President Abraham Lincoln in 1862. At the signing ceremony, President Lincoln declared the Department of Agriculture to be the "people's Department" because he said it governed an industry "in which [citizens felt] more directly concerned than in any other. .. ." Today, many American citizens do not share Abraham Lincoln's view of the USDA as being the "people's Department"; rather, they identify it as being "the last plantation" due to its long history of open discrimination against African-American farmers. While this discrimination has occurred throughout America's history, perhaps …

Origins Of The Y Genome In Elymus, Pungu Okito

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Triticeae tribe DUMORTER in the grass family (Poaceae) includes the most important cereal crops such as wheat, barley, and rye. They are also economically important forage grasses. Elymus is the largest and most complex genus with approximately 150 species occurring worldwide. Asia is an important centre for the origin and diversity of perennial species in the Triticeae tribe, and more than half of the Elymus are known to occur in the Asia. Cytologically, Elymus species have a genomic formula of StH, StP, StY, StStY, StHY, StPY, and StWY. About 40% of Elymus …

Granivores And Restoration: Implications Of Invasion And Considerations Of Context-Dependent Seed Removal, Steven M. Ostoja

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Granivores are important components of sagebrush communities in western North America. These same regions are being altered by the invasion of the exotic annual Bromus tectorum (cheatgrass) that alters physical and biological dynamics in ways that appear to promote its persistence. This research directly relates to the restoration of B. tectorum-dominated systems in two inter-related ways. First, because these landscapes have large quantities of seeds applied during restoration, it is important to determine the major granivore communities in intact sagebrush communities and in nearby cheatgrass-dominated communities. Second, it is important to develop an understanding of patterns of seed harvest …

Simulated Browsing Impacts On Aspen Suckers' Density, Growth, And Nutritional Responses, Koketso Tshireletso

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Heavy and repeated ungulate browsing on reproductive suckers has limited trembling aspen (Populus tremuloides Michx.) regeneration on many Western landscapes. However, little is known about the specific effects of season and intensity of browsing. My objectives were to determine the effects of season and intensity of clipping (simulated browsing) on suckers’ (1) density and growth characteristics, and (2) nutritional quality and quantity.

Three randomly selected stands were clear-felled in mid-July, 2005, and fenced. Simulated browsing treatments of 0%, 20%, 40%, and 60% removal of current year’s growth were randomly applied in early, mid-, and late summers of 2006 and …

Ponderosa Pine Mortality And Bark Beetle-Host Dynamics Following Prescribed And Wildland Fires In The Northern Rocky Mountains, Usa, Ryan Stephen Davis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ponderosa pine delayed mortality, and bark beetle attacks and emergence were monitored on 459 trees for 3 years following one prescribed fire in Idaho and one wildland fire in Montana. Resin flow volume (ml) was measured on 145 fire-injured ponderosa pine 2 and 3 years post-fire. Logistic regression was used to construct two predictive ponderosa pine mortality models, and two predictive bark beetle-attack models. Post-fire delayed tree mortality was greater with the presence of primary bark beetles independent of diameter at breast height (DBH) (cm), and was greater in smaller diameter trees most likely due to direct effects of fire-caused …

Livestock Foraging Behavior In Response To Interactions Among Alkaloids, Tannins, And Saponins, Tiffanny Lyman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plant secondary compounds abound in every plant mother nature has to offer. From common garden vegetables to poisonous plants, there are secondary compounds in every plant any animal, as well as we, chooses to eat. In the past, secondary compounds were mostly considered waste products of plant metabolism, but over the last several decades research has shown that these compounds play an active role in plant and animal behavior, health, and productivity. Though often seen only in terms of their negative impacts on intake and production, we are becoming increasingly aware of their beneficial roles in plant, animal, and human …

Development Theory And Domestic Agriculture In The Caribbean: Recurring Crises And Missed Opportunities, Benjamin F. Timms

Social Sciences

Caribbean development theory has long advanced a break from economic reliance on single crop exports through the promotion of domestic agriculture. Yet today the domestic agriculture sector in much of the Caribbean is underdeveloped, as the rising food import bill attests. This paper examines the historical views on domestic agriculture by development theorists with a focus on how recurring economic crises have created opportunities to advance domestic agricultural production. While internal and external forces have thwarted many of these efforts, the current global food crises may provide a sustained incentive to overcome the structural legacy of the plantation economy through …

Roman Dietetics, Monika K. Urbanski

Digitized Theses

Various sectors of Roman society ate differently. Wealthy men were virtually unrestrained in making food selections, choosing freely from all of the foods around the Mediterranean. The available array thus enabled the elite to meet and surpass the nutritional guidelines of today's World Health Organization to the extent that they may have even been subject to problems of overnutrition. The lower classes are typically assumed to have been malnourished. On the contrary, the abundance of cereals and legumes they consumed would have provided them with most essential nutrients. Lower classes would also have deliberately sought out meat and fish products …

"It's The Right Thing To Do": Why The Animal Agriculture Industry Should Not Oppose Science-Based Regulations Protecting The Welfare Of Animals Raised For Food, Angela J. Geiman

Michigan Law Review First Impressions

Since the beginning of history, people have used farm animals to assist with their work and to provide a source of food. These agricultural pursuits were not questioned; rather, they were a widely-accepted way of life. In fact, many people still say that the very purpose of livestock on this Earth is to provide these resources for mankind. As for the proper way to treat our livestock, we commonly hear farmers and livestock producers make comments like, “If we take care of the animals, they will take care of us,” and, “We treat our animals well because that’s just good …

Evaluation Of In Vitro Methods To Estimate Digestibility Of Amino Acids In The Rumen Undegraded Protein Fraction Of Feedstuffs, Sarah Boucher

Doctoral Dissertations

Soybean meal, SoyPlusRTM, dried distillers grains with solubles (DDGS), and fish meal samples were used in the evaluation of the modified three-step, the immobilized digestive enzyme assay ( IDEA), the guanidination, and the furosine in vitro procedures to estimate intestinal digestibility of amino acids in rumen undegraded protein ( RUP-AA). Identifying an in vitro method to estimate RUP-AA digestibility will allow for routine analysis of feeds for this parameter, which can lead to more accurate formulation of dairy rations. To determine the adequacy of these procedures, in vivo RUP-AA digestibility estimates were obtained using the precision-fed cecectomized rooster assay. Rumen …

The Development Of A Modular Integrated Recirculating Aquaculture System Using Porphyra (Nori) For The Bioremediation Of Marine Finfish Effluent, Jennifer Pauline Day

Doctoral Dissertations

It is crucial for the development of the fish aquaculture industry to be managed in a way that provides a reliable, long term source of products without negatively impacting the environment. The simplest form of integrated multi-tropic aquaculture (IMTA) uses a fed component (e.g. finfish) and an extractive component (e.g. seaweed) to remove the inorganic metabolites from finfish aquaculture effluent. In IMTA systems metabolic wastes become nutrients for the other cultured organisms and are incorporated into potentially valuable biomass. A demonstration-scale Modular Integrated Recirculating Aquaculture Systems (MIRAS) was constructed in a greenhouse adjacent to Great Bay Aquaculture, LLC (GBA), Newington, …

The Effects Of Using Prescribed Fire Or Mowing To Maintain Early Successional Wildlife Habitat, Kathleen M. Barrett

Master's Theses and Capstones

This study involves a comparison and results between prescribed burns and mowing in order to maintain openings in early successional stages at Great Bay National Wildlife Refuge, Newington, NH. The prescribed fire was conducted by a US Fish and Wildlife fire crew on 19 September 2001. The mowing was completed during the third week of October 2001 by staff and volunteers.

Special attention was given to non-native invasive species, with some species tending to increase with a fall burn. The mowed study sites did not seem to have a significant increase in growth or spread of invasive species.

Factors Affecting Insulin-Stimulated In Vitro Glucose Oxidation In Rat Epididymal Adipocytes, Lisa C. Merrill

Master's Theses and Capstones

Since Martin Rodbell published his collagenase method for isolating rat adipocytes from their stromal-vascular matrix in 1964, researchers have modified the procedure in an attempt to maximize results. These modifications are also purported to decrease the interlaboratory variability observed by researchers who utilize this procedure. Strict adherence to these modifications does not, however, necessarily result in robust, repeatable in vitro insulin-stimulated glucose oxidation. The purpose of this study was to optimize Rodbell's procedure for measuring in vitro glucose oxidation in rat adipocytes, and to measure the effect of meal feeding on this process.

Adipocytes from rats in 26 optimization experiments …

A Prairie Perspective On Global Warming And Climate Change: The Use Of Law, Technology, And Economics To Establish Private Sector Markets To Compliment Kyoto, Ronald C. Griffin

Journal Publications

We are in the midst of an environmental calamity that few perceive as grave. The climate is changing. Civilization is suffering. One person can do little to cope with these problems on a global scale. But farmers can do something about their farming operations to contribute less to climate change.

Today, two percent of the population feeds us. With mechanical advancements, new farm machinery, innovative practices, products, commodities, securities, and markets folk can do something to reward farmers for their efforts to slow the pace of climate change.

Investigation Of The Sex Determination Mechanisms In Summer Flounder (Paralichthys Dentatus) And Black Sea Bass (Centropristis Striata), Heidi R. Colburn

Master's Theses and Capstones

In many cultured finfish species, sexually dimorphic growth is observed, therefore, understanding the mechanisms of differentiation in fishes is necessary for successful aquaculture. Summer flounder (Paralichthys dentatus ) and black sea bass (Centropristis striata) are good candidate species for aquaculture because they easily adapt to culture conditions and have high market value. The production of monosex populations is advantageous in species exhibiting sexually dimorphic growth rates. The purpose of this research was to gain an understanding of the mechanisms involved in sex differentiation of summer flounder and black sea bass. In summer flounder, monosex female culture is beneficial because females …
