Analysis Of Structure And Function Of The Serotonin Type-3 Receptor Using Site Directed Mutagenesis, Structure Activity Relationship And Chimeric Constructs, Asha Suryanarayanan May 2005

Analysis Of Structure And Function Of The Serotonin Type-3 Receptor Using Site Directed Mutagenesis, Structure Activity Relationship And Chimeric Constructs, Asha Suryanarayanan

Chemistry and Biochemistry

The serotonin type-3 receptor (5-HT₃R) is a cation conducting ligand gated ion channel that mediates fast synaptic transmission. The 5-HT₃R belongs to the Cys loop superfamily of ligand gated ion channels that also includes the nicotinic acetylcholine, glycine and GABAa receptors. The 5-HT₃R has been implicated in several processes such as emesis, gastrointestinal motility, drug abuse, alcoholism and nociception. Studies involving the ligand-binding domain will thus aid in development of new drugs that modulate these physiological and pathophysiological processes. The ligand-binding site of this receptor is comprised of six putative loops, viz. loop A-F. The focus of this thesis was …

Vascular Endothelial Growth Factor's Angiogenic Role In Tumor Growth And Metastasis, Scott W. Kemp May 2005

Vascular Endothelial Growth Factor's Angiogenic Role In Tumor Growth And Metastasis, Scott W. Kemp

Chemistry and Biochemistry

Angiogenesis and vasculogenesis are two very important processes in the development and maintenance of mammalian health. All structures of the body (human or animal) need certain essential elements in order to live thrive and maintain. The angiogenic role is to supply and support tissue with ample vasculature, thus providing a route of access for the transportation of essential nutrients and the removal of waste in a sustained fashion. Just like normal tissue, tumorogenic tissue is no exception; neoplastic tissue has the same nutritional requirements which must be supported via vascularization. Vascular endothelial growth factor (VEGF) has been shown to be …

Investigation Of Novel Secondary Metabolites Of Colophospermum Mopane, Brian Michael Englund May 2005

Investigation Of Novel Secondary Metabolites Of Colophospermum Mopane, Brian Michael Englund

Chemistry and Biochemistry

Labdanes are a large and important class of diterpenes. Colophospermum mopane seems to be a source of 'primitive' 9, 13-epoxylabdanes. The structures of these compounds are 'missing links' in the biogenesis of 9, 13-epoxylabdanes. This research reports a new compound extracted from the seeds of C. mopane. The structures of this compound has been completely elucidated by NMR spectroscopy, and the stereochemistry of the compound supports predictions based on biosynthetic arguments. Furthermore, this thesis also corrects NMR assignments previously reported by another group.

Economic Impact Of Reindeer-Caribou Interactions On The Seward Peninsula, Stefanie Moreland Carlson May 2005

Economic Impact Of Reindeer-Caribou Interactions On The Seward Peninsula, Stefanie Moreland Carlson

Economics

The reindeer industry has persisted on the Seward Peninsula in western Alaska for more than 100 years. Since the mid 1990's the industry has been increasingly threatened by changes in Western Arctic Caribou Herd (WACH) migration paths and winter range. Free-range reindeer (Rangifer tarandus tarandus) intermingle with caribou (Rangifer tarandus granti) and migrate off designated reindeer ranges. As of spring 2003, eleven of fourteen Seward Peninsula reindeer operations were no longer commercially viable as a result of caribou induced reindeer losses. This loss is significant to an economically depressed region with few development opportunities. An economic input-output model was constructed …

Rereading Identity: The Uncanny In Janet Frame's "The Carpathians", Nancy Elizabeth Slagle May 2005

Rereading Identity: The Uncanny In Janet Frame's "The Carpathians", Nancy Elizabeth Slagle

English

Janet Frame's ultimate novel, The Carpathians, joins the New Zealand tradition of literature of the uncanny, which has addressed the problem of post-colonial identity, though the novel's metafictional and psychological complexity are uniquely Framian. The work gains richness from a psychoanalytic reading with attention to the character John Henry Brecon, who claims authorship of the novel on its final page. As ekphratic author, he employs the uncanny mode, developing motifs and themes of heimlich and unheimlich set forth by Sigmund Freud's 1919 essay, 'The Uncanny.' John Henry's novel evokes uncanny sentiments through suppression and release of his subconscious and through …

Fence-Line Interactions Among Farmed And Free-Ranging Cervids: Preliminary Results, Kurt C. Vercauteren, Justin W. Fischer, Robert Pooler, Michael J. Lavelle, Greg Phillips

United States Department of Agriculture Wildlife Services: Staff Publications

Occurrences of disease outbreaks within and near captive cervid (mule deer (Odocoileus hemionus), white-tailed deer (Odocoileus virginianus), and Rocky Mountain elk (Cervus elaphus nelsoni)) farms have recently drawn attention to these facilities. Some state wildlife and agricultural agencies have pondered making double fencing mandatory or otherwise increasing regulation of captive operations. Diseases such as Chronic Wasting Disease (CWD) and Bovine Tuberculosis (bovine TB) are a threat to captive and free-ranging cervid populations. Concerns over these and other diseases being transmitted from captive to wild cervids, and vice versa, have increased. In most cases, captive …

Wintering Strategies Of An Arctic-Nesting Goose: Costs Of Migration And Over-Wintering For Pacific Black Brant, Danielle D. Mather May 2005

Wintering Strategies Of An Arctic-Nesting Goose: Costs Of Migration And Over-Wintering For Pacific Black Brant, Danielle D. Mather

Biological Sciences

Birds wintering in different climates may have different strategies for storing and using energy. We documented changes in body morphology and composition of Pacific Black Brant (Branta bernicla nigricans) wintering in Alaska and Baja California and modeled the energetic costs of wintering at each location. We compared costs associated with two different wintering strategies: 1) to remain in an unstable and harsh environment but close to breeding grounds, or 2) to migrate long distances to a mild environment, but distant from breeding grounds. Despite dramatic differences in the timing and magnitude of energetic costs between sites, Brant stored similar amounts …

Effects Of Simulated Climate Change On The Reproductive Phenology Of Tussock Cottongrass: Implications For Growth And Reproduction Of Reindeer On The Seward Peninsula, Alaska, Merben Rellen Cebrian May 2005

Effects Of Simulated Climate Change On The Reproductive Phenology Of Tussock Cottongrass: Implications For Growth And Reproduction Of Reindeer On The Seward Peninsula, Alaska, Merben Rellen Cebrian

Biological Sciences

I investigated the experimental effects of manipulations of snowmelt on the flowering phenology and forage chemistry (digestibility and nitrogen concentration) of tussock cottongrass on the Seward Peninsula, Alaska. The early snowmelt treatment (1) accelerated reproductive phenology by 11 days, and (2) resulted in higher floral digestibility but is associated with decreased nitrogen concentration in flowers. Therefore, changes in climate that lead to changes in the timing of snowmelt can alter the timing of flowering of E. vaginatum and, consequently, its value as reindeer and caribou forage. I then used relationships between forage chemistry and body weight gain of caribou derived …

Summer Movements Of Female Moose At High Density, Kalin A. Kellie May 2005

Summer Movements Of Female Moose At High Density, Kalin A. Kellie

Biological Sciences

I examined factors influencing the summer movements of adult female moose (Alces alces gigas) at high density in interior Alaska, USA from 1996 to 2003. First, I tested how the distance moved from 4 to 0 days pre-partum was related to migration, change in cover use, reproductive maturity and individual behavior. Second, I evaluated whether long movements prior to parturition were related to predation on previous neonates. Third, I measured the scale of spatial fidelity exhibited by individuals to areas used in early spring (13 to 15 May) and areas used for parturition. Lastly, I compared summer movements of adult …

Linking Local Knowledge And Fisheries Science: The Case With Humpback Whitefish (Coregonus Pidschian) In Interior Alaska, Melissa Anne Robinson May 2005

Linking Local Knowledge And Fisheries Science: The Case With Humpback Whitefish (Coregonus Pidschian) In Interior Alaska, Melissa Anne Robinson

Biological Sciences

Humpback whitefish (Coregonus pidschian) are the main subsistence fish for the residents of the Athabascan village of Northway. Local residents' concerns over whitefish and gaps in knowledge in the scientific community about whitefish basic ecology provided a basis for collaboration between fisheries scientists, social scientists, and Northway Village. Through semi-directed interviews and participant observation, I documented and linked local and scientific knowledge about whitefish. Trust, formed in part by my engagement with the community, was essential to meaningful collaboration between local and scientific experts. Through collaboration, insights emerged about the long-distance migrations of whitefish (up to 230 km), their small-scale …

Assessment Of The Oyster Market Distribution Chain And Its Implications For Cooperative Formation In The Alaska Mariculture Industry, Erin D. Harrington May 2005

Assessment Of The Oyster Market Distribution Chain And Its Implications For Cooperative Formation In The Alaska Mariculture Industry, Erin D. Harrington

Fisheries

Market preference for attributes of Alaska-produced Pacific oysters (Crassostreas gigas) is studied using survey techniques. Oyster buyers in the continental United States are surveyed to determine the relative importance of intrinsic and extrinsic product attributes, ranging from oyster size to seasonal availability patterns. Implications of market preferences for the development of mariculture cooperatives are then considered. Extrinsic product characteristics such as a good business reputation, frequency and seasonality of product availability, and product price were relatively important to respondents when compared to intrinsic product characteristics such as size, shape, or presence of grit in the oyster.

Alien Birds In North America - Challenges For Wildlife Managers, Michael L. Avery, Eric A. Tillman May 2005

Alien Birds In North America - Challenges For Wildlife Managers, Michael L. Avery, Eric A. Tillman

Wildlife Damage Management Conference

In Executive Order 13112 "Invasive Species", an alien species is defined as one "that is not native" to a particular ecosystem. In North America today, there are nearly 100 alien bird species with self-sustaining populations. These include numerous game birds (primarily gallinaceous birds) and escaped pet birds (primarily psittacine species). Others, such as house sparrows (Passer domesticus), European starlings (Sturnus vulgaris), and mute swan (Cygnus olor), were originally introduced for aesthetic reasons or to control agricultural insect pests. The establishment of alien bird populations through purposeful or accidental introductions has resulted in numerous problems …

Overview Of Impacts Of Feral And Introduced Ungulates On The Environment In The Eastern United States And Caribbean, Martin S. Lowney, Paul Schoenfeld, William Haglan, Gary W. Witmer May 2005

Overview Of Impacts Of Feral And Introduced Ungulates On The Environment In The Eastern United States And Caribbean, Martin S. Lowney, Paul Schoenfeld, William Haglan, Gary W. Witmer

Wildlife Damage Management Conference

Non-native wild and feral ungulates have been introduced throughout the world for many centuries. Often the reasons for introductions were narrow in scope and benefits or the ungulates escaped or were released. Justifications for some introductions have included providing hunting opportunity, meeting cultural and dietary needs of people, fund raising, and aesthetics. Evaluations about the impacts to the environment, native wildlife, livestock, and people were most likely looked at in a narrow prism or not fully evaluated. Ungulates commonly introduced in the Eastern United States and Caribbean islands over the last 150 years included white-tailed deer, sika deer, hogs, horses, …

Feral And Introduced Carnivores: Issues And Challenges, Gary Witmer, Bernice U. Constantin, Frank Boyd May 2005

Feral And Introduced Carnivores: Issues And Challenges, Gary Witmer, Bernice U. Constantin, Frank Boyd

Wildlife Damage Management Conference

Feral and invasive carnivores have been intentionally or unintentionally introduced to many parts of the world for a variety of reasons. Once established, they have often caused significant impacts to endemic species because of their predatory nature and, in numerous cases, have altered ecosystem structure and function in important conservation areas. They can also cause competition for native predators, hybridization with native species, losses to livestock and companion animals, and disease hazards. We provide examples of the extent of introductions, resulting impacts, and efforts to control or eradicate these populations. Working with introduced or feral carnivores presents many challenges to …
