Responsiveness Of Cobb Mv × 700 Broilers To Dietary Amino Acid And Energy Density, Craig William Maynard

Graduate Theses and Dissertations

As new broiler crosses are introduced to the industry, it is of paramount importance to understand their nutritional digressions from previous and other modern broilers. In particular, amino acids (AA) and dietary energy have been identified as key drivers of live performance and carcass composition. In addition, increased nutrient density in broiler diets have been linked to an increase in breast muscle myopathies such as white striping and woody breast. Therefore, a series of trials were conducted to determine the responsiveness of live performance, carcass characteristics, and breast muscle myopathies of Cobb MV × 700 broilers to dietary AA and …

Comparison Of Calculated Energy Expenditure To Measured Energy Expenditure In Overweight And Obese Burn Patients In An Icu Setting: A Retrospective Study, Elle Maree Skinner, Deborah A. Cohen, Orrin B. Myers, Diana Gonzales-Pacheco

Individual, Family, and Community Education ETDs

Burns cause massive dermal wounds. Wound healing elicits a significant catabolic response and increase in energy expenditure, and thus, calorie needs. Overfeeding and/or underfeeding the overweight and obese critically ill patient can increase complications. Indirect Calorimetry (IC) is considered the ‘gold standard” for the measurement of Energy Expenditure (EE). Predictive equations are calculated to estimate EE instead. This study is a retrospective chart review. The difference between predictive energy expenditure (via Curreri formula) and measured IC were analyzed via non-parametric Wilcoxon signed rank match paired tests. Curreri equation prediction was analyzed on the ability to match IC (0% over or …

Flower Visitation In Relation To Pollen And Nectar Nutrition: Implications For Pollinator Habitat And Conservation, Megan E. Leach

Electronic Theses and Dissertations

Pollination of both wild and crop plants is at a crossroads; honey bee populations are experiencing losses at a higher rate than ever before, and some native bee species are declining in abundance to the point of being listed as endangered species. A few examples of these threats include pesticide exposure, habitat loss, and climate change. In response to bee population declines, conservation efforts have been initiated to increase habitat quality for bees by planting pollinator reservoirs or gardens. Plants provide nutrition to bees in the form of pollen and nectar. Several studies have shown links between higher nutritional quality …

The Effect Of Wild Blueberry Anthocyanins And Phenolic Acids On Innate Immunity: The Compliment System, Vasiliki Papakotsi

Electronic Theses and Dissertations

Ingestion of berries containing polyphenols is associated with lower risk of inflammatory, metabolic, cardiovascular and degenerative diseases. Diet has been shown to modulate the activation of the complement system, a set of over 50 proteins present in the circulation and tissues that reacts in response to damage or microbial encounter and is critical for the maintenance of homeostasis. Imbalanced activation is tightly correlated with inflammation and various pathologies. Wild blueberries are a rich source of anthocyanins and phenolic acids, which can be found in plasma shortly after consumption. Given the involvement of both complement and polyphenols in the modulation of …

Antiproliferative Activity Of Carotenoids, Phenolic Compounds, And Volatile Terpenoids In Carrots (Daucus Carota L.), Brittany Frederick

Graduate Theses and Dissertations

Epidemiological studies have shown an association between high carrot consumption and low prevalence of cancer. This observation has been thought to be attributed to carrot carotenoids. Despite this, various intervention trials have displayed no changes in incidence or increased incidence of cancer with carotenoid supplementation. It is possible that carrot phenolics are responsible for this association, though this has not been widely accepted. Volatile terpenoids from carrots have not been studied in this regard. Therefore, the primary objective of this study was to compare the antiproliferative effects of carotenoids, phenolics, and volatile terpenoids extracted from carrots on Caco-2 colon cancer …

Nutritional Virulence Of Legionella Pneumophila., Ashley M. Best

Electronic Theses and Dissertations

Legionella pneumophila is an environment organism that parasitizes a wide range of protozoa. Growth within the environmental host primes L. pneumophila for infection of human alveolar macrophages when contaminated aerosols are inhaled. Intracellular replication within either host requires the establishment a replicative niche, known as the Legionella-containing vacuole (LCV). Biogenesis of the LCV depends on the type IVb translocation system, the Dot/Icm, to translocation >320 effectors into the host cytosol. Effectors are responsible for preventing lysosome fusion to the LCV, recruitment of ER-derived vesicles to the LCV, and modulation of a plethora of host processes to promote the intracellular …

Food Insecurity And Age Of Menarche: Using A Biocultural Approach And Life History Theory To Assess Risks Of Food Insecurity Among Girls In Tampa Bay, Fl, Mecca Burris

USF Tampa Graduate Theses and Dissertations

Using life-history theory within a biocultural perspective, this research explores whether household food insecurity correlates with early or delayed menarche among adolescent females in Tampa Bay, Florida. Early onset of puberty and menstruation is connected with numerous health consequences including growth stunting, obesity, type-2 diabetes, adult-onset asthma, reproductive cancers, increased risk for depression, behavioral problems, and early sexual activity which increases the risk for STIs and ovarian cancer. Early menarche also seems to disproportionally impact disadvantaged and minority groups. While there are many known factors that influence age at menarche (e.g.: genetics, diet), little is understood regarding the effect of …

Pcb Disruption Of Gut And Host Health: Implications Of Prebiotic Nutritional Intervention, Jessie Baldwin Hoffman

Theses and Dissertations--Pharmacology and Nutritional Sciences

Exposure to environmental pollutants poses numerous risk factors for human health, including increasing incidence of cardiovascular disease and diabetes. Persistent organic pollutants, such as polychlorinated biphenyls (PCBs) have been strongly linked to the development of these chronic inflammatory diseases and the primary route of exposure is through consumption of contaminated food products. Thus, the gastrointestinal tract is susceptible to the greatest levels of these pollutants and is an important facet to study.

The first two hypotheses of this dissertation tested that exposure to PCBs disrupts gut microbiota directly (in vitro) and within a whole body system. PCB exposure …

Examining The Credentials Of Food Bloggers And The Online Environment Of Food Blogs, Jessica Coburn

Master's Theses and Doctoral Dissertations

This study evaluated characteristics of food blogs and food bloggers that potentially affect food choices. It was hypothesized that most food bloggers would not have a nutrition-related degree and food blog environments wouldn’t be supportive of health-conscious food choices. A cross-sectional study was conducted using a novel evaluation tool on 187 blogs, out of which 100 blogs met inclusion criteria. Because some blogs had multiple bloggers, two samples were investigated: 111 bloggers (n1 = 111) and 100 food blogs (n2 = 100). Data were gathered from a randomized list of blogs taken from americanfoodbloggers.com. Results showed that 6% of bloggers …

Exploring Lactate’S Role In Appetite Regulation Following High-Intensity Exercise, Luke W. Vanderheyden

Theses and Dissertations (Comprehensive)

Background: Intense-exercise has demonstrated an appetite suppressing effect post-exercise, however the involved mechanisms are not well understood. Lactate appears to be one viable mechanism as it has been found to bind to receptors on acylated ghrelin to inhibit release in cell culture. As sodium bicarbonate (NaHCO₃) can alter lactate accumulation post-exercise without manipulating exercise-intensity, it presents an intriguing means to investigate lactate’s potential role. Purpose: To examine the role of lactate on appetite using NaHCO₃ to alter blood lactate concentrations during high-intensity exercise. Methods: Eight recreationally active males completed two identical exercise sessions of low-volume high-intensity interval …

Nutritional Ecology Of Aphaenogaster Ants In Response To Climate Change, Katie A. Miller

Graduate College Dissertations and Theses

Climate change is predicted to impact organismal nutritional ecology. Increased temperatures can directly accelerate physiological rate processes, which in turn, impact nutritional requirements. Climate change can also impact organisms indirectly by altering the quality and quantity of nutritional resources, creating the potential for nutritional mismatch between what nutrients are available in the environment and what organisms require. Investigation of organismal stoichiometry, particularly the balance of carbon, nitrogen, and phosphorus content of organisms, can help illuminate the extent to which changes in climate may impact organism nutritional ecology. Ants represent an excellent system to examine stoichiometry because they occur across a …

Effects of enzymatically hydrolyzed yeast (EHY) and supplementation frequency (FREQ) on immune parameters among beef cows and calves was evaluated. Eighty multiparous (parity = 4.2 ± 0.3) cows were fed a common brome hay-based diet (CP = 8.0 ± 0.17%). Cows were blocked by expected calving date and stratified by body condition score (BCS) before random assignment of treatment. Beginning 88 ± 5 d prior to parturition, cows were provided 1 kg daily or 3 kg every 3 d of a soybean hull-based supplement (CP = 34.0, % of DM) that contained 0 or 3 g/kg EHY. The daily supplement …

Protein And Lipid Characterization Of Acheta Domesticus, Bombyx Mori, And Locusta Migratoria Dry Flours, Emily N. Brogan

Graduate Theses, Dissertations, and Problem Reports

Cricket (Acheta domesticus), silkworm pupae (Bombyx mori), and locust (Locusta migratoria) dry flours were obtained to examine the biochemical properties and composition of the flours. This study aimed to characterize the protein and lipid components of three insect species utilizing proximate composition analyses, amino acid composition analysis, protein solubility, SDS-PAGE, fatty acid composition analysis, and thin layer chromatography to determine lipid classes, and lipid extraction efficiency. Kjeldahl determined the cricket, locust, and silkworm flours contained 72.0%, 53.1%, and 71.2% protein, respectively. All proximate composition analyses were significantly (p<0.05) different between species. Amino acid composition analysis revealed that the flours contained 3.6-3.9% and 0.90-1.5% of lysine and methionine, respectively. Many countries have cereal grains and legumes as a staple in their diet that contain these limiting amino acids. Essential amino acids were 22% of total amino acids. Protein solubility revealed that the three species studied were most soluble in alkaline environments with highest protein solubility occurring at pH 13 at 66% solubility in silkworm. Lowest solubility occurred in more acidic conditions between pH 4-5. SDS-PAGE revealed five major protein fractions with estimated molecular weights of 27 (cuticle proteins), 41 (arginine kinase), which has been identified as an allergen in shrimp, 42 (actin), 71 (hemocyanin), and 220 myosin) kDa. Soxhlet extraction determined cricket, silkworm, and locust flours contained 15.4%, 33.3%, and 11.4% lipid, respectively. The only omega-3 fatty acid found in the flours was α-linolenic acid. Silkworm flour contained the most α-linolenic acid at 33.3% of total fatty acids, followed by locust (13.7%), and cricket (0.6%). TLC resolved lipids for typical lipid classes. The four major lipid classes noted were triacylglycerol, free fatty acid, cholesterol, and phospholipid. Lipid extraction efficiency found that the organic solvents chloroform and methanol had the highest lipid extraction yield in both cricket (69.3%) and locust (93.0%). Methyl-tertiary-butyl ether (MTBE) extracted lipids most efficiently in the silkworm. Proteins and lipids found in insects need to be isolated to further or commercial use.
