Paratransgenic Control Of Vibriosis In Shrimp Aquaculture, Bobban Subhadra

Biomedical Sciences ETDs

Infectious diseases are an increasing threat to shrimp farming industries worldwide and account for nearly $3 billion of annual economic loss. The need to devise novel approaches against these infectious agents is pressing, as traditional methods are insufficient to ward off infections. The main aim of this study was to apply paratransgenesis to control infectious agents mediating shrimp diseases. As proof-of-concept we showed that Artemia, a food source in shrimp aquaculture, internalized bacteria expressing recombinant proteins. Stable expression and retention of these marker molecules up to 10 hours after feeding with the transgenic bacteria were evident within the gut of …

Purpose

To carry out pattern analyses of dietary and lifestyle factors in relation to risk of esophageal and gastric cancers.

Methods

We evaluated risk factors for esophageal adenocarcinoma (EA),esophageal squamous cell carcinoma(ESCC), gastric cardia adenocarcinoma (GCA), and other gastric cancers (OGA) using data from a population-based case-control study conducted in Connecticut, New Jersey, and western Washington state. Dietary/lifestyle patterns were created using principal component analysis (PCA). The impact of the resultant scores on cancer risk was estimated through logistic regression.

Results

PCA identified six patterns: meat/nitrite, fruit/vegetable, smoking/alcohol, legume/meat alternate, GERD/BMI, and fish/vitamin C. Risk of each cancer under study …

The Evolutionary Ecology Of Human Infancy, Amanda Veile

Anthropology ETDs

Infancy is a time of profound energetic trade-offs, and in many South American native groups, infant growth is stunted and mortality by infectious disease is high. The goal of this dissertation was to explore the nature of human infancy from a life history theoretical perspective. Specifically, I investigated infant growth, feeding patterns, and thymic development in two South American native populations, the Tsimane of Bolivia and the Pumé of Venezuela. This broad goal is addressed through four specific goals: 1) to model the weaning transition using behavioral data collected in Tsimane communities where infants experience varying mortality rates, 2) to …

Evaluation Of Algorithm Thresholds For Crop Canopy Sensor-Based In-Season Nitrogen Application In Corn, Brian Theodore Krienke

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Nitrogen fertilizer is frequently the most limiting nutrient in corn production. Typically most nitrogen is applied before planting. Since nitrogen can leave the soil system fairly easily, the result can be an inefficient use of nitrogen fertilizer. Previous research has shown increased efficiency with no reduction in yield by applying nitrogen later in the season when the crop is actively growing, with rates regulated spatially through the use of active crop canopy sensors. This study evaluated the potential for N cutoff thresholds using a sufficiency index as the threshold value for areas with poor stand or an unrecoverable N deficiency. …

A Study Of The Factors That Influence Early Stages Technology Investment By Food Enterprises, Grainne Kavanagh

Masters

To promote industry sustainability and to catalyze links between publicly-funded knowledge providers and companies, the Irish government has invested significantly in food-orientated research and development. This project aims to facilitate a greater understanding of the motivations and barriers influencing the decision by small and medium-sized food enterprises (SME) to invest in technological innovation, emanating from research conducted in publicly-funded organisations. A critical review of the literature was used to develop a framework for investigating the uptake of technological innovations from sources external to the company. In order to ground this framework within the specific context of the Irish food industry, …

Natural Resource Management Faculty Publications

Increases in global aquaculture production, compounded with limited availabilities of fish meal for fish feed, has created the need for alternative protein sources. Twinscrew extrusion studies were performed to investigate the production of nutritionally balanced feeds for juvenile yellow perch (Perca flavescens). Five isocaloric (~3.06 kcal/g) ingredient blends, adjusted to a target protein content of 36.7% db, were formulated with 0%, 10%, 20%, 30%, and 40% distillers dried grains with solubles (DDGS) at an initial moisture content of 5–7%db, with appropriate amounts of fish meal, fish oil, whole wheat flour, corn gluten meal, and vitamin and mineral premixes. …

Effects Of Dietary Distillers Dried Grains With Solubles And Soybean Meal On Extruded Pellet Characteristics And Growth Responses Of Juvenile Yellow Perch, Travis W. Schaeffer, Michael L. Brown, Kurt A. Rosentrater

Natural Resource Management Faculty Publications

A 126-d feeding trial was performed to investigate graded combinations of distillers dried grains with solubles (DDGS) and soybean meal (SBM) in diets formulated for yellow perch Perca flavescens. Six experimental diets contained DDGS and SBM at 0 and 31.5% (dry matter basis), respectively (0/31.5 diet), 10 and 26% (10/26), 20 and 20.5% (20/20.5), 30 and 15% (30/15), 40 and 9.5% (40/9.5), and 50 and 4% (50/4) to obtain similar levels of crude protein (mean ± SE = 30.1 ± 0.2%), crude lipid (16.7 ± 0.7%), and digestible energy (13.5 ± 0.2 kJ/g). Fourteen fish (initial individual weight = 19.1 …

Multiple Levels Of Synergistic Collaboration In Termite Lignocellulose Digestion., Michael E. Scharf, Zachary J. Karl, Amit Sethi, Drion G. Boucias

Department of Entomology Faculty Publications

In addition to evolving eusocial lifestyles, two equally fascinating aspects of termite biology are their mutualistic relationships with gut symbionts and their use of lignocellulose as a primary nutrition source. Termites are also considered excellent model systems for studying the production of bioethanol and renewable bioenergy from 2nd generation (non-food) feedstocks. While the idea that gut symbionts are the sole contributors to termite lignocellulose digestion has remained popular and compelling, in recent years host contributions to the digestion process have become increasingly apparent. However, the degree to which host and symbiont, and host enzymes, collaborate in lignocellulose digestion remain poorly …

Effects Of Xenobiotics And Phytotoxins On Reproduction In Food Animals, Kip E. Panter, Bryan L. Stegelmeier

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The influence of natural toxicants and anthropogenic compounds on reproduction in food animals is significant in its economic impact, and the subject requires more research and further experimental substantiation. Confounding factors such as stress, nutritional status, season of the year, animal species involved, genetic variability, disease conditions, management factors, and so forth exacerbate the difficulty of making an accurate diagnosis and thereby may impede progress to improve reproductive performance on an individual operation. The interaction between the reproductive system and xenobiotics (reproductive toxicology) is a relatively new area of study and a subject of increasing interest, especially in the area …

Asynchronous And Synchronous Teaching And Learning In High-School Distance Education, Elizabeth Murphy, Maria A. Rodríguez-Manzanares, Michael K. Barbour

Education Faculty Publications

This paper presents the results of an inductive, interpretive analysis of the perspectives of 42 Canadian high school distance education (DE) teachers on asynchronous and synchronous online teaching. The paper includes a conceptual overview of the affordances and constraints of each form of teaching. Findings provided insight into the following aspects of asynchronous and synchronous online teaching: degree of use; the tools used; the contexts in which each occur; students’ preferences; and limitations. Pedagogy emerged as more important than media for both asynchronous and synchronous online teaching. Synchronous online teaching relied on teacher- rather than student-centred approaches. Asynchronous online teaching …

Comparison Of Soil Chemistry And Microbial Communities That Inhabit The Rhizosphere Of Native And Non-Native Grasses Of The Lower Rio Grande Valley, Jacqueline Valencia

Theses and Dissertations - UTB/UTPA

Non-native grasses can modify the soils they invade. This study investigated microbial variation among native and non-native grasses in the Lower Rio Grande Valley. We hypothesized that rhizospheres of non-native grasses would support a higher density of microorganisms; therefore microbial communities of invasive plants would exploit more carbon sources than those of native plants. A second hypothesis stated that Streptomyces bacteria from the rhizosphere of non-native grasses would be better competitors. Samples of grasses, and soil from their respective rhizospheres were obtained in Arroyo City, TX. Results indicated a higher bacterial colony density, total activity and number of substrates utilized …

Aquaculture Of Octopus Species: Present Status, Problems And Perspectives, Elisabeth Berger

The Plymouth Student Scientist

The aquaculture of Octopus species is currently an active field of research around the world, but economic viability is not yet achieved. Here, the current state of knowledge with respect to Octopus water quality and nutritional requirements, reproduction, juvenile and adult stages in culture systems, which comes mainly from just one species, Octopus vulgaris (Cuvier, 1797), is reviewed. Some critical considerations are addressed and new research lines are proposed.

What Do We Know About The Causes And Consequences Of Salmonid Social Hierarchies From Laboratory Experiments?, Lewis Eaton

The Plymouth Student Scientist

The main focus of this review will be to examine the current understanding of the causes and consequences of salmonid hierarchies as well as the implications to wild populations and aquaculture. Salmonid dominance hierarchies readily form under laboratory conditions, this has allowed extensive research into social structures. There is limited research into the causes of social status, however, the cause is likely to be a combination of standard metabolic rate, body size and prior competitive experience. A wide range of research outlines the consequences of social status from behavioural changes in aggression and submission to physiological changes in disease resistance, …

Asian Medical Journal and Alternative Medicine

Diabetes Mellitus is a chronic disease which can cause many complications seriously affecting quality of life and longevity. Good management of blood sugar level reduces and avoids complications. Dietary management is one of very important factors to control blood sugar level. Since the difference regulations from people about proper time for a monk consumption, i.e. not eating before 6.00 AM and not after noon and taking food from the donor presenting to the hand or in the bowl, it may affect the control normal blood sugar level. In this study, we developed and evaluated the diabetic mellitus diet-counseling pattern in …

A “Principled Resolution”: The Fulcrum For Bioethics Mediation, Nancy Neveloff Dubler

Law and Contemporary Problems

The concept of a "principled resolution" is the foundation for bioethics mediation. Dubler presents the core bioethical principles that support the creation of principled resolutions as fulcrums for resolving disagreements in the healthcare setting. These disputes may arise among medical providers, between medical providers and patients, or among members of a patient's family and can be managed or resolved by bioethics mediation using the conceptual tool of a principled resolution.

Phytosterol Stearate Esters Elicit Similar Responses On Plasma Lipids And Cholesterol Absorption But Different Responses On Fecal Neutral Sterol Excretion And Hepatic Free Cholesterol In Male Syrian Hamsters, Mark M. Ash, Jiliang Hang, Patrick Dussault, Timothy P. Carr

Patrick Dussault Publications

The dietary impact of specific phytosterols incorporated into phytosterol fatty acid esters has not been elucidated. Therefore, we tested the hypothesis that phytosterol esters containing different sterol moieties (sitosterol, sitostanol, or stigmasterol) but the same fatty acid moiety (stearic acid) produce different effects on cholesterol metabolism. Male Syrian hamsters were fed sitosterol, sitostanol, and stigmasterol stearate esters (25 g/kg diet) in an atherogenic diet containing cholesterol (1.2 g/kg) and coconut oil (80 g/kg). The phytosterol stearates produced no decrease in cholesterol absorption or plasma non–high-density lipoprotein cholesterol despite a reduction in liver free cholesterol in hamsters fed both sitosterol and …

Multistate Mark-Recapture Analysis Reveals No Effect Of Blood Sampling On Survival And Recapture Of Eastern Kingbirds (Tyrannus Tyrannus), Lucas J. Redmond, Michael T. Murphy

Biology Faculty Publications and Presentations

The experimentally supported and prevailing opinion is that blood sampling has few to no long-term effects on survival of birds when conducted properly, and blood sampling has become a vital addition to the toolbox of many ornithologists. However, many of the studies that concluded that blood sampling had negligible effects on birds used approaches that did not account for temporary emigration and probability of capture. To date, the only study to have done so found that blood sampling had a strong negative effect on survival. We conducted a mark–recapture analysis of 8 years of banding and bleeding data on Eastern …

Serum Igf-1 Concentrations Change With Soy And Seaweed Supplements In Healthy Postmenopausal American Women, Jane Teas, Mohammad R. Irhimeh, Susan Druker, Thomas G. Hurley, James R. Hébert, Todd M. Savarese, Mindy S. Kurzer

Faculty Publications

Insulin-like growth factor 1 (IGF-1) is an anabolic hormone important for growth and development. However, high-circulating serum concentrations in adults are associated with increased risk of postmenopausal breast cancer. Nutritional status and specific foods influence serum IGF-1 concentrations. Breast cancer incidence is typically low in Asian countries where soy is commonly consumed. Paradoxically, soy supplement trials in American women have reported significant increases in IGF-1. Seaweed also is consumed regularly in Asian countries where breast cancer risk is low. We investigated the possibility that seaweed could modify soy-associated increases in IGF-1 in American women. Thirty healthy postmenopausal women (mean age …

Outcomes Assessment Of Role-Play Scenarios For Teaching Responsible Conduct Of Research, Stephanie N. Seiler, Bradley J. Brummel, Kerri L. Anderson, Kyoung Jin Kim, Serena G. Wee, C. K. Gunsalus, Michael C. Loui

Research Collection School of Social Sciences

We describe the summative assessment of role-play scenarios that we previously developed to teach central topics in the responsible conduct of research (RCR) to graduate students in science and engineering. Interviews with role-play participants, with participants in a case discussion training session, and with untrained students suggested that role-playing might promote a deeper appreciation of RCR by shifting the focus away from wanting to simply “know the rules.“ We also present the results of a think-aloud case analysis study and describe the development of a behaviorally-anchored rating scale (BARS) to assess participants' case analysis performance.
