Preparation Of Proteins And Peptides From Heat-Stabilized Defatted Rice Bran Via Solid State Fermentation And Investigating For Skin Health, Ali A. Bisly
Graduate Theses and Dissertations
Heat-stabilized defatted rice bran (HDRB) is an abundant and inexpensive agro-industrial by-product of rice milling and rice oil extraction process. Furthermore, HDRB is a potential source of proteins. However, the direct protein extraction has low yield of protein due to the impact of heat stabilization and oil extraction process which made the HDRB proteins bound and interact with other components. This research is based on using solid-state fermentation (SSF), which is a natural and cost-effective approach to facilitate protein extraction from HDRB using Bacillus subtilis (natto) Takahashi as a microorganism.

Investigation On Bacterial Signaling Through Generation Of A Ppgpp Biosensor, Andrew Robinson
Investigation On Bacterial Signaling Through Generation Of A Ppgpp Biosensor, Andrew Robinson
Undergraduate Honors Theses
Guanosine tetraphosphate (ppGpp) is a bacterial signaling molecule involved in activating the stringent response, a cellular reaction to environmental stress that downregulates cell division and metabolism processes to conserve nutrients. The stringent response is implicated in some instances of antibiotic persistence, so broadening the current understanding of ppGpp signaling is useful. This thesis seeks to generate a ppGpp biosensor that will bind ppGpp and emit fluorescent light in its presence, which will allow for improved research into the pathways and functions of the signaling molecule. To generate a novel ppGpp biosensor, I converted a biosensor previously used to detect cyclic …
Evaluating Methods To Determine The Maximum Oxygen Consumption By The Gulf Killifish, Fundulus Grandis, Sylvia Mullen
Evaluating Methods To Determine The Maximum Oxygen Consumption By The Gulf Killifish, Fundulus Grandis, Sylvia Mullen
Senior Honors Theses
Metabolic rate is an essential feature of animal physiology and ecology. The rate of aerobic metabolism, as determined by oxygen consumption rate (MO2), is influenced by a variety of factors, including body size, temperature, and activity levels. Maximum aerobic metabolic rate (MMR) reflects the physiological capacity of an animal for oxygen extraction and utilization. As such, MMR is argued to be an important feature of an animal’s life history. For fish, MMR is frequently estimated as the peak MO2 immediately following an exhaustive chase, although several studies indicate that this value may underestimate MMR. Rather, MMR may be attained during …

Effects Of Providing Novel Feedstuffs To Livestock On Production And Skeletal Muscle Growth, Laura A. Motsinger
Effects Of Providing Novel Feedstuffs To Livestock On Production And Skeletal Muscle Growth, Laura A. Motsinger
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
As the population increases and available land for food production decreases, it is necessary for livestock producers to continually work towards increasing livestock production efficiency. In livestock operations, feed accounts for the majority of input costs associated with raising livestock. As such, it is necessary to improve growth and production of livestock animals, while also optimizing feed utilization. Different feedstuffs can be included in the diet of livestock animals to maximize growth and production. However, the effects of some of these novel feedstuffs on growth and production of livestock animals has not been elucidated. As such, we investigated the effects …

Electronic Theses and Dissertations
ABSTRACT
Social-emotional learning targets the development of positive interpersonal relationships, empathy, emotional regulation, healthy identities, personal/collective goal orientation, and responsibility in the decision-making process (CASEL Organization, 2021). Schools, however, have the main objective of ensuring that academic measures are met. Linking social-emotional learning and skills to the school system’s principal goal, academic results, can facilitate the greater implementation of such programs within the school setting. This systematic literature review examined the relationship between social-emotional learning programs in schools and academic outcomes, such as grades, test scores, or grade point averages. Secondly, it explored the relationship between students’ social-emotional skills and …
Macronutrient Availability Shapes Host Response To Infection And Feeding Behavior, Weston Gerald Perrine
Macronutrient Availability Shapes Host Response To Infection And Feeding Behavior, Weston Gerald Perrine
Graduate Theses and Dissertations
Macronutrients in the diet are vital to the physiological processes necessary for an organism to effectively clear a pathogen. Diet can be important to a host’s susceptibility to infection and severity of pathology, though results can vary across host-pathogen systems (Sen et al. 2016). Manipulating the ratio of specific macronutrients in the diet is an effective method to begin understanding how individual macronutrients, rather than food types, have on immune responses. Using an avian host-pathogen system, I explored the effects of dietary macronutrient composition, specifically lipid and protein content, on disease pathology and behavior of canaries (Serinus canaria) infected with …
Targeting Inflammation In Heat-Stressed Wethers Improves Growth And Efficiency And Alters Body Composition: A Brief Exploration And Application Of Extension Principles, Micah Samuel Most
Targeting Inflammation In Heat-Stressed Wethers Improves Growth And Efficiency And Alters Body Composition: A Brief Exploration And Application Of Extension Principles, Micah Samuel Most
Department of Animal Science: Dissertations, Theses, and Student Research
The objective of our first study was to determine how administering anti-inflammatory dexamethasone and ω-3 polyunsaturated fatty acid (PUFA)-rich fish oil affects growth efficiency and body composition in heat-stressed finishing lambs. Commercial wethers were randomly assigned to be fed under heat stress (35-40 ℃) or thermoneutral (19 ℃, n = 10) conditions for 30 d, and controls were pair-fed to eliminate differential feed intake. Heat-stressed wethers were randomly assigned to receive clinical-dose dexamethasone IM injections every 72 h, twice daily fish oil capsule oral boluses, or placebos. Heat stress decreased (P < 0.05) growth and efficiency, but dexamethasone and fish oil supplementation recovered these performance measures. Heat stress also decreased (P < 0.05) predictive body composition metrics that were at least partially improved by administration of dexamethasone and fish oil. Proximate analyses of muscles showed that heat stress decreased (P < 0.05) percentage of protein and increased (P < 0.05) percentage of intramuscular fat, neither of which was improved by dexamethasone or fish oil. Immunohistochemistry revealed that heat stress decreased (P < 0.05) myoblast differentiation and muscle fiber size, but anti-inflammatory supplementation recovered differentiation only. Plasma IGF-1 concentrations were not different among groups throughout the study. These findings demonstrate how heat stress-induced inflammation contributes to impaired growth, efficiency, and body composition observed in heat-stressed feeder lambs. However, targeting inflammation with dexamethasone or fish oil recovers many of these deficits.
