Blubber Transcriptome And Proteome Responses To Repeated Adrenocorticotropic Hormone Administration In A Marine Mammal, Jared Deyarmin
University of the Pacific Theses and Dissertations
Chronic physiological stress impacts animal fitness by catabolizing metabolic stores and suppressing reproduction and immunity. This can be especially deleterious for capital breeding carnivores, such as marine mammals, which rely on lipid stores accrued during intensive foraging to sustain prolonged periods of fasting associated with reproduction. Therefore, chronic stress may cause a decrease in fitness in these animals, leading to population declines and potentially detrimental shifts in food web dynamics as a result. However, the impacts and indicators of chronic stress in animals are currently poorly understood. To identify downstream mediators of repeated stress responses in marine mammals, adrenocorticotropic hormone …
Eye Movement Related Single-Unit Recording In The Nucleus Reticularis Tegmenti Pontis In The Alert Monkey, William Franklin Crandall Jr.
Eye Movement Related Single-Unit Recording In The Nucleus Reticularis Tegmenti Pontis In The Alert Monkey, William Franklin Crandall Jr.
University of the Pacific Theses and Dissertations
Nucleus Reticularis Tegmenti Pontis (NRTP) is a structure which lies in the mid-brain ventral to the oculomotor complex. Anatomical studies strongly implicate it in oculomotor function as most of its inputs and outputs are to systems previously shown to be intimately involved in eye movement generation--superior colliculus (SC) and cerebellum. These reports show an integrative structure with inputs and outputs distributed in a way well suited for performing relay and feedback tasks. Physiological data in the alert, trained monkey has been gathered in an attempt to characterize these neurons and to classify them in functional terms. Three monkeys were trained …

The Functional Development Of The Adrenal-Sympathetic Nervous System In Neonatal And Adolescent Swine, Sidney Koon Hung Woo

The development of the animal after birth is marked by complex changes. Certain periods are particularly important and have been defined as "critical periods" (Krecek, 1971). Two processes are important to the survival of the animals during these times. The process of "adaptation" involves the maturation of specific physiological systems according to the needs of the neonatal animal, and is dictated by the external environment. The process of "tolerance" renders the neonate relatively unresponsive to a stressor as compared to the adult and protects the animals from over-responding the depleting vital resources until it is physiologically mature. An example of …
Solubilization Of Acetylcholinestrerae From Subcellular Components Of Mammalian Brain Tissue, John E. Taylor
Solubilization Of Acetylcholinestrerae From Subcellular Components Of Mammalian Brain Tissue, John E. Taylor
University of the Pacific Theses and Dissertations
Since all chemical and electrical input into the cell / occurs via its plasma membrane, many pharmacological agents and hormones initiate their effects by interacting with receptor sites on the plasma membrane or by passing through the cell membrane and interacting with other membranes within the cell. Generally, the precise mechanisms by which these events occur remain relatively unclear. It was thought for many years that the cell membrane was a relatively static structure which allowed molecules to enter the cell at a rate dependent upon their degree of lipid solubility. However, more recently an increasing body of evidence suggests …
