The Roles of Dietary Nitrate in Bone and the Gut in an Ovarian Hormone-deficient Rodent Model

Creator:: Conley, Melissa N.
Abstract:: Osteoporosis is a common metabolic bone disease, affecting a third of women and a fifth of men over age 65. In the US, annual health care costs associated with osteoporosis are estimated to be over $20 billion. Osteoporosis is associated with increased fracture risk, which has been demonstrated to predict...

Student, teaching assistant, and faculty learning during innovation in an introductory biology course

Creator:: Blair, Lesley
Abstract:: This study examined the dynamics of student, teaching assistant (TA), and faculty learning in relationship to implementation of a genetic technologies project in a university introductory biology course. Research focused on the types of learning that occurred and the various factors impacting that learning. Study participants included 25 undergraduate non-science...

Middle school science teachers' personal growth and professional development : what do they mean?

Creator:: Holmes, Frank L.
Abstract:: A teacher may say, "I have twenty years of experience," but just what does it mean? This study suggests explanations for the meaning of "Experience," not by looking at the number of years in a classroom, but at what teachers did in those years that could make the teaching experience...

Decision support systems for forest biodiversity management : a review of tools and an analytical-deliberative framework for understanding their successful application

Creator:: Gordon, Sean N.
Abstract:: The complexity of forest management has increased with the scope of resources of concern and the level of scrutiny from stakeholders. The design and use of specialized computer software, often referred to as “decision support systems” (DSS), is one method for helping managers deal with this complexity. DSS have proven...

Partnerships between secondary/elementary science teachers and laboratory-based scientists : delineating best practices

Creator:: Henderson, Sandra
Abstract:: Given the high probability of national and federal research laboratories continuing to sponsor science education partnerships between their staff and classroom science teachers and the dearth of research in this area, this study set out to delineate best practices associated with such partnerships for the purpose of increasing the effectiveness...

Conceptions of the nature of science and worldviews of preservice elementary science teachers in Taiwan

Creator:: Liu, Shiang-Yao
Abstract:: This exploratory investigation aimed to identify preservice science teachers' conceptions of the nature of science (NOS), and worldviews that represent their culturally dependent beliefs about the world, in the context of Taiwan. The interrelationships between the responses elicited from both the assessments of NOS understandings and worldviews were examined. Participants...

From pesticide degradation products to legacy toxicants and emerging contaminants : novel analytical methods, approaches, and modeling

Creator:: Forsberg, Norman D.
Abstract:: Environmental toxicologists and public health officials are responsible for assisting in the identification, management, and mitigation of public health hazards. As a result, there is a continued need for robust analytical tools that can aid in the rapid quantification and characterization of chemical exposure. In the first research phase, we...

Morphological variability and seed dormancy of Amelanchier (Rosaceae) grown in Oaxaca, Mexico

Creator:: Cruz-Cruz, Efrain
Abstract:: The purpose of this research was to determine whether hybridization between Amelanchier denticulata. (H.B.K.) Koch and Amelanchier nervosa (Decaisne) StandL occurs in Oaxaca, Mexico, and to evaluate components of yield and germination characteristics and seed dormancy of Amelanchier denticulata. Amelanchier nervosa and Amelanchier denticulata samples and morphological characters were used...

The role of the plasminogen activator system in the etiology of ovarian follicular cysts in dairy cattle

Creator:: McNeel, Anthony Kent
Abstract:: Cystic ovarian disease (COD) is an anovulatory condition in cattle that afflicts between 6-18% of all dairy cows in the US. Ovulation is dependent on the plasminogen activator (PA) family of proteases and protease inhibitor for proteolysis, culminating in follicular rupture. Failure of the follicle to ovulate suggests an aberration...

The role of leptin in normal and pathological bone resorption

Creator:: Philbrick, Kenneth Alan
Abstract:: Particles generated from wear of prosthesis joint bearing surfaces induce inflammation and promote pathological periprosthetic osteoclast-mediated bone resorption (osteolysis). Obesity increases the risk of prosthesis failure. However, despite being morbidly obese, leptin-deficient ob/ob mice are resistant to osteolysis. These findings suggest that leptin exerts effects that act to increase particle-induced...
