Effects Of Feed Additive Strategies For Commercial Broiler Production And Gut Health, Courtney Elizabeth Ennis

Theses and Dissertations

The total removal of antibiotic growth promoters (AGP) from poultry feed is underway in the United States. Feed additive strategies will be utilized to maintain the efficient growth, health, and economic value found with current commercial broiler production. Experiment 1 investigated the effects of feeding an encapsulated butyric acid and zinc product (EBAZ) at 3 inclusions on d 0- 49 Ross x Ross 708 male and female broiler performance, blood chemistry, and cecal short-chain fatty acid content. These data suggest that EBAZ can be safely included at 0.5 g/kg and at 2.5 g/kg into diets for Ross x Ross 708 …

Efficacy Of Bentonite And Calcium Montmorillonite Clays At Reducing Aflatoxin M1 Transfer In Lactating Holsteins, Sarah Caitlin Allen

Theses and Dissertations

Aflatoxins are naturally occurring carcinogens found on grains, particularly in warmer climates. Because of their carcinogenic properties, they are strictly regulated and are only allowed in minimal amounts. Aflatoxin B1, the most potent naturally occurring carcinogen known, is metabolized in the liver to form aflatoxin M1, which is present in the milk of lactating animals. If aflatoxin concentrations are elevated above legal limits, the milk cannot be used for human consumption. Because of this, research has been conducted to evaluate ways to mitigate its absorption in the animal and prevent transfer to the milk. One such way is through the …

Body Fat Determination Of Stock-Type Horses In Varying Body Condition By Carcass Dissection, Rump Fat Thickness, And Deuterium Oxide Dilution And Fatty Acid Composition Of Adipose Tissues, Emily Nicole Ferjak

Theses and Dissertations

The primary objectives of the study were to compare 2 body fat (%, BF) prediction methods for stock-type horses by rump fat thickness (RFT) and D2O dilution with actual tissue fat analysis by near-infrared spectroscopy (NIR) and to identify the relationships among BF, BCS, and physical measurements. Secondary objectives were to determine the fatty acid (FA) composition of mesenteric (MS), cardiac (CD), subcutaneous (SC), intermuscular (IM), and leaf fat (LF) and to identify relationships between of FA composition and BCS in horses. Results indicated that D2O dilution is an accurate predictor of BF, and RFT alone does not accurately predict …

Incidence Of Salmonella Spp. In Farming Environments And Food Facilities By Improved Detection, Lurdes G. Siberio-Perez

Theses and Dissertations

Environmental samples from food processing facilities and production (farms) were taken and analyzed for the presence of indicator organisms and Salmonella spp. on food contact (FC) and nonood contact (NFC) surfaces. Salmonella was isolated from both FC and NFC surfaces of a fruit and catfish-processing plant environment, but not from a dairy processing plant or from produce packaging facility environments. Scatter plots did not show a relationship between indicator organisms and the presence of Salmonella in processing environments, regardless of the facility/environment. Salmonella ser. Gaminara and Salmonella ser. Give were prevalent in the fruit processing environment. Persistence could not be …

Management Of Plant-Parasitic Nematodes Using Gene Manipulation And Biological Nematicides Biological Nematicides, Weasam Adnan Radhi Aljaafri

Theses and Dissertations

Soybean cyst nematode (H. glycines), reniform nematode (R. reniformis), and Root-Knot nematode (M. incognita) are three damaging plant-parasitic nematodes on soybean. Syntaxin proteins are involved in the process of membrane fusion. T wo G. max syntaxin genes (Gm-SYP22-1, and Gm-SYP22-2) that were similar in amino acid composition have been found to contribute to the ability of Glycine max to defend itself from infection by the plant parasitic nematode Heterodera glycines. Syntaxin genes SYP22-1 and SYP22-2 were identified to be expressed specifically in syncytia undergoing a resistant reaction to H. glycines parasitism. The Gm-SYP22-1 and Gm-SYP22-2 genes were isolated by molecular …

Impact Of Nanotechnology-Based Semen Purification On Reproduction Of Gilts And Developmental Performance Of Offspring, Casey Lynn Durfey

Theses and Dissertations

Semen contain a heterogeneous population of viable and non-viable (damaged) spermatozoa. Proportions of non-viable spermatozoa interfere with male fertility, with available techniques unable to selectively remove prior to breeding. Nanobiotechnology may allow removal, enriching semen with high quality spermatozoa for improved productivity. Here, we applied double nanopurification with boar semen using functionalized magnetic nanoparticles. Non-viable and viable spermatozoa were magnetically separated and verified through various microscopy imaging. Viable (nanopurified) spermatozoa showed no additional damages. Nanopurification did not interfere with sperm motility and viability, with beneficial effects on motion parameters. Nanopurified spermatozoa maintained fertility following insemination, with resulting offspring indicating no …

A Privacy Calculus Model For Personal Mobile Devices, Gregory J. Bott

Theses and Dissertations

Personal mobile devices (PMDs) initiated a multi-dimensional paradigmatic shift in personal computing and personal information collection fueled by the indispensability of the Internet and the increasing functionality of the devices. From 2005 to 2016, the perceived necessity of conducting transactions on the Internet moved from optional to indispensable. The context of these transactions changes from traditional desktop and laptop computers, to the inclusion of smartphones and tablets (PMDs). However, the traditional privacy calculus published by (Dinev and Hart 2006) was conceived before this technological and contextual change, and several core assumptions of that model must be re-examined and possibly adapted …

Exploratory Study On The Role Of Phycotoxins In Dinoflagellates, Entesar B. A. E. S. Alrubaiaan

Open Access Theses

Phycotoxins are secondary metabolites produced by dinoflagellates and other algae. Despite their notorious role in neurotoxicity to higher trophic level species, it is still unknown why algae produce phycotoxins. This study reviewed the available literature, that forms our current knowledge on the potential ecological roles of phycotoxins. It also experimentally examined three untested hypotheses. First, the role of phycotoxins in chemical defense against bacteria was tested. The second hypothesis examined the role of toxins in dissipating excess energy from intense light. Lastly, the role of toxins in alleviating copper toxicity was tested. Two bloom-forming toxic dinoflagellates (Alexandrium catenella a …

Abl Kinase Regulation By Braf/Erk And Cooperation With Akt In Melanoma, Aditi Jain, Rakshamani Tripathi, Courtney P. Turpin, Chi Wang, Rina Plattner

Pharmacology and Nutritional Sciences Faculty Publications

The melanoma incidence continues to increase, and the disease remains incurable for many due to its metastatic nature and high rate of therapeutic resistance. In particular, melanomas harboring BRAF^V600E and PTEN mutations often are resistant to current therapies, including BRAF inhibitors (BRAFi) and immune checkpoint inhibitors. Abl kinases (Abl/Arg) are activated in melanomas and drive progression; however, their mechanism of activation has not been established. Here we elucidate a novel link between BRAF^V600E/ERK signaling and Abl kinases. We demonstrate that BRAF^V600E/ERK play a critical role in binding, phosphorylating and regulating Abl localization and Abl/Arg activation …

The Role Of Affective Forecasting And The Impact Bias In Nutritional Health Behaviors, Matthew D. Fallon

Masters Theses

Previous literature on affective forecasting has studied its role in health decisions, but there is little research investigating affective forecasting in diet choices and eating behaviors. The present study collected affective forecasts from 43 college participants before eating an indulgent snack and then observed emotions immediately after eating the snack. We predicted that emotion predictions would be significantly stronger than observed emotions, in support of previous literature on the impact bias. We also predicted that optimism would predict a stronger impact bias and that extraversion and neuroticism would have a role in forecasts and observed emotions. Contrary to our hypothesis, …

Effect Of Static Stretching Or Foam Rolling On Hamstrings Range Of Motion And Strength, Grant Wiseman

Research Papers

The purpose of this study was to examine the acute effects of foam rolling and static stretching on the hamstrings isokinetic force production as well as knee joint range of motion. Eleven healthy, moderately experienced, male college students participated in the study. It was hypothesized that foam rolling and static stretching would both see significant improvements in range of motion. Static stretching was also believed to have decreases in force production while foam rolling would stay relatively the same. Two treatments, static stretching and foam rolling, were established for within participants pretests and posttests. Both treatments were 5 minutes. Results …

Cardio-Metabolic Benefits Of Plant-Based Diets., Hana Kahleova, Susan Levin, Neal Barnard

Medicine Faculty Publications

Cardio-metabolic disease, namely ischemic heart disease, stroke, obesity, and type 2 diabetes, represent substantial health and economic burdens. Almost one half of cardio-metabolic deaths in the U.S. might be prevented through proper nutrition. Plant-based (vegetarian and vegan) diets are an effective strategy for improving nutrient intake. At the same time, they are associated with decreased all-cause mortality and decreased risk of obesity, type 2 diabetes, and coronary heart disease. Evidence suggests that plant-based diets may reduce the risk of coronary heart disease events by an estimated 40% and the risk of cerebral vascular disease events by 29%. These diets also …

Saha Cardiovascular Research Center Faculty Publications

Objective

The upregulated expression of heparin binding EGF-like growth factor (HB-EGF) in the vessel and circulation is associated with risk of cardiovascular disease. In this study, we tested the effects of HB-EGF targeting using HB-EGF-specific antisense oligonucleotide (ASO) on the development of aortic aneurysm in a mouse aneurysm model.

Approach and results

Low-density lipoprotein receptor (LDLR) deficient mice (male, 16 weeks of age) were injected with control and HB-EGF ASOs for 10 weeks. To induce aneurysm, the mice were fed a high fat diet (22% fat, 0.2% cholesterol; w/w) at 5 week point of ASO administration and infused with angiotensin …

Combating Stress With Yoga: A Theoretical Model Of Self-Regulation, Sierra K. Wait

LSU New Orleans Theses and Dissertations

Exposure to environmental stressors may challenge children’s developing self-regulatory abilities and increase their risk of developing emotional and behavior problems. Interventions aimed at improving children’s self-regulatory skills, specifically emotion regulation and attentional control, may reduce children’s risk for adjustment problems. The present study proposed a novel theoretical model which describes how participation in yoga may increase children’s self-regulatory skills and increase children’s mindfulness, or the ability to focus attention on the present moment. Both self-regulation and mindfulness were expected to be associated with fewer anxiety problems. Components of the theoretical model were evaluated using a very small sample of at-risk, …

Compression and cold therapy used separately have shown to reduce negative effects of tissue damage. The combining compression and cold therapy (cryocompression) as a single recovery modality has yet to be fully examined. To examine the effects of cryocompression on recovery following a bout of heavy resistance exercise, recreationally resistance trained men (n =16) were recruited, matched, and randomly assigned to either a cryocompression group (CRC) or control group (CON). Testing was performed before and then immediately after exercise, 60 minutes, 24 hours, and 48 hours after a heavy resistance exercise workout (barbell back squats for 4 sets of 6 …
