Influence of lipids (arachidonic acid and cholesterol) on calcium signalling in rodent pancreatic beta cells
DownloadFall 2010
Ca2+ is an important mediator of stimulus-secretion coupling in beta cells of the pancreatic islets, which secrete insulin in response to elevation in plasma glucose concentration. I studied the actions of two lipids, arachidonic acid (AA) and cholesterol, on enzymatically-dissociated single...

Investigating the Influence of Therapeutic Hypothermia on Stroke-Induced Intracranial Pressure in a Rat Model of Intracerebral Hemorrhage
DownloadSpring 2016
Elevated intracranial pressure (ICP) is a potentially life threatening complication after intracerebral hemorrhagic stroke (ICH). Animal and clinical studies suggest that mild (~33ºC) therapeutic hypothermia (TH) reduces ICP after ischemic stroke and traumatic brain injury (TBI). Since TH has...

Method, degree and lineage of prenatal maternal stress: effects on inflammatory and stress marker profiles of reproductive tissues and pregnancy outcomes
DownloadSpring 2023
Lopes, Nayara Gabriela Antunes
Prenatal maternal stress (PNMS) is any type of stress that pregnant women and animals experience. It was reported that over 70% of pregnant women experience low to moderate stress, while 6% experience high stress. Growing evidence indicates that PNMS influences maternal and offspring health...

Numbers, reproduction and growth of Clethrionomys rutilus (Mammalia: Cricetidae) from islands in the upper Mackenzie River and adjacent mainland
Download1976
Masters thesis. Populations of the northern redbacked vole, Clethrionomys rutilus, were studied on seven islands in the upper Mackenzie River, and at two sites on adjacent mainland.

Fall 2014
With well over 3,400 described species, snakes undoubtedly represent one of the most successful groups of reptiles. Much has been written about their ecology, behavior, anatomy, relationships and evolution. However, despite the debate about the origin of this taxonomic group dating back to the...

Fall 2018
A full understanding of the evolution of novel forms requires inference about their origins through the study of variation in extant taxa and clues from the fossil record. However, the origins of morphological diversity in many groups are obscured by the scarcity of transitional fossils or...

Osteology, Taxonomy, Phylogeny, and Body Shape Changes of Eocene Catostomid and Problematic Catostomid Fishes
DownloadFall 2016
Extant catostomid fishes occupy diverse aquatic ecosystems and niches in North America (NA). Less than 3% of catostomid taxonomic richness, or two species, are found outside of NA in Asia. Such adjunct and unbalanced distribution pattern has been established since the late Oligocene, when...

Palaeoenvironment and palaeoecology of three Cretaceous snakes: Pachyophis, Pachyrhachis, and Dinilysia
Download2001
Caldwell, M. W., Albino, A. M.
The palaeoecology of three Late Cretaceous snakes is evaluated. Pachyophis woodwardi Nopcsa, 1923 and Pachyrhachis problematicus Haas, 1979, are Cenomanian in age and are found in carbonate rocks deposited in marine inter-reef basin environments of the European and African Tethys Sea. Dinilysia...

Fall 2017
Leafrollers moths are one of the most ecologically and economically important groups of herbivorous insects. These Lepidoptera are an ideal model for exploring the drivers that modulate the processes of diversification over time. This thesis analyzes the evolution of Choristoneura Lederer, a well...
