Cloning And Characterization Of A Novel Oocyte-Specific Gene Fbos Encoding An F-Box Protein In Rainbow Trout (Oncorhynchus Mykiss), Lei Wang
Graduate Theses, Dissertations, and Problem Reports (ETD)
Oocyte-specific genes play critical roles in oogenesis, folliculogenesis and early embryonic development. Through analysis of expressed sequence tags (ESTs) from a rainbow trout oocyte cDNA library, we identified a novel transcript which is represented by multiple ESTs derived only from the oocyte cDNA library. Analysis of tissue distribution of the novel Fbos gene by reverse transcription polymerase chain reaction revealed that the novel gene is only expressed in unfertilized oocytes but not in 10 somatic tissues examined. Northern blot analysis showed the transcript size is approximately 2.1 kb. The full-length cDNA sequence for the novel gene Fbos was obtained by …

Properties Of A Dehydroalanine Analog Of Glutathione: A Reactive Electrophilic Busulfan Metabolite, Cody J. Peer
Graduate Theses, Dissertations, and Problem Reports (ETD)
Gamma-Glutamyldehydroalanylglycine (EdAG) is a dethiolated, electrophilic metabolite of glutathione (GSH) derived from the Phase II conjugation of GSH with busulfan catalyzed by glutathione S-transferase (GST). It was demonstrated in this dissertation that EdAG could be successfully synthesized and shown to be a metabolite of busulfan from in vitro metabolism by enzymes in human liver cytosol. The electrophilic EdAG was reactive toward the cellular thiols cysteine and glutathione (GSH), and toward cysteine residues in reduced bovine insulin B-chain and bovine serum albumin in vitro , as well. EdAG was demonstrated to be a reversible noncompetitive inhibitor of GSTs, specifically GSTA1-1 at …
The Evaluation Of A Nutrition Education And Fitness Program With A Contest Component Among College Students Using The Re-Aim Framework, Michelle L. Bartlett
The Evaluation Of A Nutrition Education And Fitness Program With A Contest Component Among College Students Using The Re-Aim Framework, Michelle L. Bartlett
Graduate Theses, Dissertations, and Problem Reports (ETD)
Only recently have practitioners and researchers targeted the population of college students in studying interventions aimed at increasing health behaviors. There is evidence that a proportion of college students are making attempts on their own to remedy weight gain and poor physical fitness with little or no guidance, which is reflected in consistently rising obesity rates in this population. Thus, the need for organized and effective interventions is illustrated. The impact of an intervention can be determined through evaluation research. Although the RE-AIM model has not yet been used to evaluate single-site, university-sponsored, college-student weight-loss/fitness programs, it provided a useful …
Mechanism By Which Dietary Polyunsaturated Fat Regulates Lipogenic Gene Expression, Alison Bloom Kohan
Mechanism By Which Dietary Polyunsaturated Fat Regulates Lipogenic Gene Expression, Alison Bloom Kohan
Graduate Theses, Dissertations, and Problem Reports (ETD)
Primary hepatocytes treated with non-esterified polyunsaturated fatty acids have been used as a model for describing the inhibitory effects of dietary polyunsaturated fats on lipogenic gene expression. This model resembles starvation or uncontrolled diabetes but not dietary fat ingestion, which is delivered to liver via chylomicron remnants. Chylomicron remnants enriched with polyunsaturated fatty acids stimulate a unique pattern of intracellular signaling. These remnants enhance p38 mitogen activated protein kinase (MAPK) activity but do not inhibit insulin signaling or induce extracellular-signal related kinase (ERK) or AMP-activated protein kinase (AMPK) activation as do non-esterified polyunsaturated fatty acids. Polyunsaturated fatty acids-enriched remnants and …

Coconut Oil Enhancement Of Conjugated Linoleic Acid Induced Body Fat Loss And Lipolysis In Mice, Siri Manasa Ippagunta
Graduate Theses, Dissertations, and Problem Reports (ETD)
Dietary conjugated linoleic acid (CLA) causes a body fat loss that is enhanced when mice are fed coconut oil (CO) compared to soy oil (SO). The objectives were to determine if CLA feeding altered proteins involved in lipolysis. Male mice (n = 80; 3 wk old) were fed 7% SO or CO diets for 6 wk then 0 or 0.5% CLA for 12d. A body fat index was calculated: (retroperitoneal (RP) + epididymal (EPI) fat pads)*100/body weight. Lipolysis was determined by non-esterified fatty acid (NEFA) and glycerol release from EPI & RP explants. The relative expression of perilipin, phosphorylated perilipin …
Variation In, And Contributing Factors Of Placental Efficiency In Swine, Tiffany Ann Wilmoth
Variation In, And Contributing Factors Of Placental Efficiency In Swine, Tiffany Ann Wilmoth
Graduate Theses, Dissertations, and Problem Reports (ETD)
Placental efficiency, defined as fetal weight divided by placental weight, has been shown to be involved in litter size. Breeds that are more prolific (12-13 pigs per litter) have feto-placental units with higher placental efficiencies. However, domestic commercial breeds have much smaller litters of about 9.5 pigs per litter. Placental size is vastly different, such that high placental efficiency pigs have smaller, more vascularized placentae. Even within an individual litter two piglets with similar body weights may be grown on placentae that are different in size. The placenta of the least efficient feto-placental unit may be up to 50% bigger …
Effects Of Delayed Fat Supplementation On Post-Prandial Rumen Metabolism, Lamb Quality And Fatty Acid Composition Of Rumen Effluent, Quinn Stephan Baptiste
Effects Of Delayed Fat Supplementation On Post-Prandial Rumen Metabolism, Lamb Quality And Fatty Acid Composition Of Rumen Effluent, Quinn Stephan Baptiste
Graduate Theses, Dissertations, and Problem Reports (ETD)
Sheep farmers have an option to incorporate fat supplements into the ration of grazing ruminants. Farmers choosing this option will have to select a time for offering that supplement. It might be practical to feed the supplement in the morning or evening. However, the time at which that supplement is fed should not compromise nutrient digestion or the enhancement of ruminant product fatty acid composition. Consequently, the effects of feeding a fat enriched supplement, at a delayed time on rumen metabolism, lamb quality, and fatty acid composition of effluent digesta were investigated in three experiments. In experiment 1, treatment (time …

Graduate Theses, Dissertations, and Problem Reports (ETD)
Experiments were conducted to improve the physical and nutritional quality of pelleted feed. One experiment focused specifically on improvement of pellet quality using functional muscle proteins. A second experiment examined the effects of increasing mixer-added fat (MAF) on feed manufacture variables, broiler performance variables and carcass composition. In experiment 1, muscle proteins (myofibrillar and sarcoplasmic) were recovered using isoelectric/solubilization precipitation, and a functional paste (TPP) was formed by mixing recovered proteins with typical surimi additives. Trout protein paste was included in broiler diets at 0, 2.5 or 5%. A tap water treatment (3.9%) was included to match the moisture added …
The Effects Of Omega-3 Polyunsaturated Fatty Acids On Ampk Activation And Lipid Metabolism In Skeletal Muscle, Myra Ellen Woodworth-Hobbs
The Effects Of Omega-3 Polyunsaturated Fatty Acids On Ampk Activation And Lipid Metabolism In Skeletal Muscle, Myra Ellen Woodworth-Hobbs
Graduate Theses, Dissertations, and Problem Reports (ETD)
Intramyocellular lipid accumulation and low lipid oxidative capacity contribute to the formation of insulin resistance, but omega-3 polyunsaturated fatty acids (n-3 PUFA) are shown to attenuate insulin resistance caused by high levels of saturated fats. The AMP-activated protein kinase (AMPK) promotes lipid oxidation and oxidative gene expression, highlighting its possible role in promoting insulin sensitivity by reducing lipid content and improving oxidative capacity. This study evaluated the effects of n-3 PUFA on the AMPK pathway and alterations to lipid content, oxidative markers, and insulin signaling proteins in a muscle cell culture model, with the hypothesis that n-3 PUFA would attenuate …

A Daily Process Analysis Of Short -Term Physical Activity Goal Pursuits In Midlife: Changes In Goal Processes, Physical Activity, And Subjective Well -Being, Eric A. Goedereis
Graduate Theses, Dissertations, and Problem Reports (ETD)
The prevalence of obesity in the United States increases with age, with the highest rates corresponding to midlife. Midlife health behaviors may play a contributing role in many of the health problems commonly associated with advanced age. Health psychologists who have embraced a life-span developmental perspective argue that it is important to consider the individual developmental trajectories of health and successful aging. Goal-setting has been shown to account for significant variance in physical activity, which has a variety of health-promoting benefits. In order to investigate individual variability in the daily processes of physical activity goal pursuit within a sample of …

Role Of Endothelin 1 In Follicular And Luteal Function In The Sheep, Fernando P. Perea-Ganchou
Graduate Theses, Dissertations, and Problem Reports (ETD)
Three experiments were carried out in order to examine the role of endothelin in follicular steroid secretion in vitro and in spontaneous and PGF2alpha-induced luteolysis in sheep.;In experiment 1, it was hypothesized that endothelin 1 (END1) acting through its receptors ENDRA and/or ENDRB, on granulosal cells of ovine preovulatory follicles would inhibit steroid production, and therefore, prevent the premature luteinization of granulosal cells of those follicles. Data from estrogen-inactive 20 follicles collected from 13 ewes were analyzed. Accumulation of E 2 and P4 by cultured granulosal cells was not affected by either LH or END1 or the END receptor blockers. …
