Inositol And Rhizopine Metabolism - Key Pathways For Competitive Host Nodulation In Sinorhizobium Meliloti, Petra R. A. Kohler

Dissertations

"The rhizopine concept suggests that rhizopines, which are inositol derivatives, function as nutritional mediators and play an important role in host-bacteria interactions. This thesis analyzes the hypothesis that not only rhizopines but also naturally occurring inositol isomers, such as myo-, D-chiro-, and scyllo -inositol, function as nutritional mediators in the Sinorhizobium meliloti - alfalfa nitrogenfixing symbiosis. The idhA-encoded myoinositol dehydrogenase is responsible for the first step in the degradation of myo- and D-c/z/ra-inositol. A different dehydrogenase, IolY, was found to be essential for growth with scyllo-'mositol. The iolA and iolCDEB genes were required for the further degradation of myo-, D-chiroand …

Glucosamine-Induced Insulin Resistance In Primary Rat Hepatocytes And The Role Of Selenium As An Insulin Mimetic, Sandhya N. Adiyodi Veetil

Dissertations

Type 2 diabetes is mediated by insulin resistance, the inability of insulin to elicit a normal biological response in insulin responsive tissues. Several cellular models have been utilized to determine the mechanism of induction of insulin resistance but questions remain unanswered. One model, implicates the products of the Hexosamine Biosynthetic Pathway (HBP) in the induction of insulin resistance under hyperglycemia. The major end product of HBP, UDP-GlcNAc, is the substrate for O-GlcNAc transferase, an enzyme that catalyzes the O-GlcNAcylation of numerous proteins. This modification may play a role in induction of insulin resistance and thus needs to be evaluated in …

Abstention To Consumption: The Development Of American Vegetarianism, 1817-1917, Adam Daniel Shprintzen

Dissertations

The history of vegetarianism in the United States has long been shrouded in myth, assumption and obfuscation. Vegetarianism as a vital ideological and political movement has often been presented--even by its proponents--as a product of twentieth century modernism, reflecting a rise in ethical consumer awareness. The historical record of the nineteenth century, however, tells a very different story. The notion that dietary choices could be connected with larger social and political goals was formulated during, and changed dramatically in the nineteenth century. This dissertation charts the rise and evolution of vegetarianism in the United States from 1817 until 1917.

Avian Developmental Endocrinology: The Effects And Role Of Yolk Hormones, Sibling Dynamics, And Life-History, Corinne Patricia Kozlowski

Dissertations

Inter-specific variation of the endocrine system is an underlying component for variation in avian life-history. Females deposit hormones into the yolks of their eggs, and embryonic exposure affects nestling phenotype. Hormones are also produced endogenously by developing nestlings, further influencing their behavior and physiology. This dissertation examines the role of the endocrine system in development by focusing on several different avian taxa. Yolk hormone concentrations often vary across the laying order and may mediate hatching asynchrony. These patterns were characterized in two species that lay asynchronously hatching clutches: Eastern screech owls (Megascops asio) and cockatiels (Nymphicus hollandicus). The patterns described …

Individual-Based Modeling Of White-Tailed Deer (Odocoileus Virginianus) Movements And Epizootiology, Lene Jung Kjaer

Dissertations

White-tailed deer (Odocoileus virginianus) are important game mammals and potential reservoirs of diseases of domestic livestock, so diseases of deer are of great concern to wildlife managers. In many situations, models can be useful for integrating existing data, understanding disease transmission patterns, and predicting effects on host populations. Individual-based modeling (IBM) has become more commonplace in ecology as a tool to link individual behavior to population dynamics and community interactions, especially for gauging the effects of management actions. Spatially explicit IBMs are especially useful when ecological processes, such as disease transmission, are affected by the spatial composition of the environment. …
