A Proteomic Analysis Of Differentiation In The Mammary Epithelium, Laura Therese Strand

Master's Theses

While a great deal is known about the changing hormonal environment and the structural development of the mammary gland from pregnancy to lactation, very little is known about the molecular mechanisms governing differentiation of the mammary epithelium into a milk-secreting phenotype. It is important to acknowledge the diversity among the mammary glands of different species in order to better understand applications in human health and the dairy industry. In this study, we examined global protein expression during two states of differentiation in mammary epithelial cells from two species: in vitro proliferating and differentiated MAC-T cells (a bovine immortal cell-line), and …

Effects Of Ovariectomy, Seasonal Changes, And Anatomical Position On The Compact Bone Remodeling As Seen In The Adult Ovine Model, Erica Wong

Master's Theses

The purpose of this study is to characterize the compact bone remodeling of the ovariectomized ewe and its effectiveness as an animal model for studies of postmenopausal osteoporosis. The use of animal models is a beneficial way to evaluate the effectiveness of medical devices and therapeutic agents for treating diseases. The ovine model is an attractive option because of its large size and similar bone remodeling to humans. However, this species, like most animals, does not undergo a natural menopause, making an ovariectomy necessary for studies of estrogen depletion. The OVX (ovariectomized) sheep has been widely accepted as a model …

The Suitability Of Ground Date (Phoenix Dactylifera L.) Pits And Ghaf (Prosopis Cineraria L.) Pods As Horticultural Growth Media Or Soil Amendments, Saeed Khalifa Alshaali

Theses

The UAE and its neighboring countries are encountering scarcity of water resources and soil degradation due to salinization. The current over-exploitation of aquifers by the agricultural sector is a major concern for the government. Open field production of forage as a feed for camels, cows and small ruminants requires particularly high amounts of irrigation water. Greenhouse production of fodder might save water, but would require a suitable growth substrate that is readily available in the UAE, and ideally constitutes a palatable fodder itself. The objective of this study was to evaluate the suitability of ground D.pits and G.pods as growth …

Innovation For Inclusive Growth: Towards A Theoretical Framework And A Research Agenda, Gerard George, Anita M. Mcgahan, Jaideep Prabhu

Research Collection Lee Kong Chian School Of Business

Inclusive innovation, which we define as innovation that benefits the disenfranchised, is a process as well as a performance outcome. Consideration of inclusive innovation points to inequalities that may arise in the development and commercialization of innovations, and also acknowledges the inequalities that may occur as a result of value creation and capture. We outline opportunities for the development of theory and empirical research around this construct in the fields of entrepreneurship, strategy, and marketing. We aim for a synthesis in views of inclusive innovation and call for future research that deals directly with value creation and the distributional consequences …

Glutathione-Mediated Neuroprotection Against Methylmercury Neurotoxicity In Cortical Culture Is Dependent On Mrp1, Travis Rush, Xiaoqian Liu, Andrew B. Nowakowski, David H. Petering, Doug Lobner

Biomedical Sciences Faculty Research and Publications

Methylmercury (MeHg) exposure at high concentrations poses significant neurotoxic threat to humans worldwide. The present study investigated the mechanisms of glutathione-mediated attenuation of MeHg neurotoxicity in primary cortical culture. MeHg (5 μM) caused depletion of mono- and disulfide glutathione in neuronal, glial and mixed cultures. Supplementation with exogenous glutathione, specifically glutathione monoethyl ester (GSHME) protected against the MeHg induced neuronal death. MeHg caused increased reactive oxygen species (ROS) formation measured by dichlorodihydrofluorescein (DCF) fluorescence with an early increase at 30 min and a late increase at 6 h. This oxidative stress was prevented by the presence of either GSHME or …

Evidence On The Human Health Effects Of Low-Level Methylmercury Exposure, Margaret R. Karagas, Anna L. Choi, Emily Oken, Milena Horvat, Rita Schoeny, Elizabeth Kamai, Whitney Cowell, Philippe Grandjean, Susan Korrick

Dartmouth Scholarship

Background: Methylmercury (MeHg) is a known neuro-toxicant. Emerging evidence indicates it may have adverse effects on the neuro-logic and other body systems at common low levels of exposure. Impacts of MeHg exposure could vary by individual susceptibility or be confounded by bene-ficial nutrients in fish containing MeHg. Despite its global relevance, synthesis of the available literature on low-level MeHg exposure has been limited.

Objectives: We undertook a synthesis of the current knowledge on the human health effects of low-level MeHg exposure to provide a basis for future research efforts, risk assessment, and exposure remediation policies worldwide.

System Dynamics Implementation Of A Model Of Population And Resource Dynamics With Adaptation, Takuro Uehara, Yoko Nagase, Wayne Wakeland

Complex Systems Faculty Publications and Presentations

We build and analyze a dynamic ecological economic model that incorporates endogenous innovation on input substitutability. The use of the system dynamics method allows us to depart from conventional equilibrium thinking and conduct an out-of-equilibrium (adaptation) analysis. Simulation results show that while improvement in input substitutability will expand an economy, this change alone may not improve sustainability measured by indicators such as utility-per-capita and natural resource stock. It could, however, be possible that in combination with other technological progress, improvement in input substitutability will contribute to sustainable development. Sensitivity analysis also indicates a possible complication with the use of exogenous …

Identifying And Measuring Food Deserts In Rural Ohio, Francis Mulangu, Jill Clark

Journal of Extension

The purpose of our article is twofold. First, we introduce a framework for U.S. Extension educators to measure the extent of food access at any scale when information about food carried by retailers is limited. Second, we create a baseline for the Ohio Food Policy Council so that work to increase food access in rural areas will have a benchmark to measure success. Three broad aspects of food accessibility—physical, economic, and healthful—are considered. Lack of larger supermarkets, lack of competition, and high concentrations of nearby fast food alternatives are three issues that deserve attention in rural Ohio.

The JIA team (physical education teacher, classroom teacher, school nurse, and parent) work together to provide a supportive environment as students set goals to improve food choices and increase activity. Following the program, students demonstrated increased self efficacy and knowledge of health behaviors. Students also reported, 1) drinking less soda and sugar added drinks, 2) spending more time being physically active, and 3) consuming four servings of dairy products more frequently.

Extension Newsletters And Individual Counseling: Equally Effective In Changing Worksite Wellness Participants Dietary Intakes, Kristi Chipman, Ruth Litchfield

Journal of Extension

The Affordable Care Act provides impetus for Extension efforts in worksite wellness. The study reported here examined the influence of two worksite wellness interventions, newsletters and individual counseling. Surveys examined dietary and physical activity behaviors of participants pre- and post-intervention (N=157). Descriptive statistics, paired samples t-tests, and repeated measures ANOVA identified change in nutrient intakes; McNemar's Test evaluated physical activity participation. Both interventions significantly increased fruit/vegetable servings, vitamin C, potassium, magnesium, and dietary fiber while decreasing total fat, saturated fat, percent fat, and dietary cholesterol. There is opportunity for Extension in worksite wellness programming and research to strengthen evidence-based practice.

Extension Professionals' Strengths And Needs Related To Nutrition And Health Programs, Ninfa Pena-Purcell, Elaine Bowen, Virginie Zoumenou, Ellen R. Schuster

Journal of Extension

We report results of a Web-based nationwide survey of nutrition and health Extension specialists representing 42 states. Survey items (n = 36) assessed five areas: curriculum review, nutrition and physical activity, professional training, communication, and evaluation. An internal curriculum review was common, but few states shared their criteria or process on-line. The majority of respondents reported discussing physical activity, and over half lead physical activities. Most favored on-line professional development training and a one-stop website for sharing information and resources. Evaluation data were most commonly collected for food safety, healthy eating and physical activity, and food resource management.

The Need For Accurate Prediction Equations For The Carcass Lean Content Of Pigs, Allan P. Schinckel, Clinton P. Rusk

Journal of Extension

Prediction equations for pork carcass lean percentage are widely used in Extension, teaching, and research. Prediction equations using carcass or live animal measurements are used in carcass contests, live animal evaluation, and marketing. Fat–free lean gain is used to estimate the daily lysine requirements for pigs in swine nutrition guides. The use of inaccurate equations has substantial economic impact. Extension specialists must make the effort to confirm the accuracy of the equations they recommend for use. Standards of prediction accuracy and biases must be developed to assure that accurate equations are developed and recommended for industry use.

Tea Time: Raising Awareness And Support For Extension, Nancy K. Franz, Chris Fahey
