Compensatory Mechanisms And T Cell Migration In Mouse Models Of Dopaminergic Loss, Kristi M. Anderson
Compensatory Mechanisms And T Cell Migration In Mouse Models Of Dopaminergic Loss, Kristi M. Anderson
Theses & Dissertations
Parkinson’s disease (PD) is the most common neurodegenerative movement disorder and second most common neurodegenerative disorder. PD is characterized by the selective loss of dopaminergic neurons and dopamine neurotransmitter within the substantia nigra and termini in the striatum. Progressive loss of dopaminergic neurons occurs over many years in PD, and by the time movement disorder symptoms manifest, up to 50-70% of dopaminergic neurons have been lost. Several aspects of PD pathology have been described in detail, but a better understanding of PD progression is needed to develop more efficient treatments.
Motor symptoms associated with PD do not manifest until significant …

Normal Glycolytic Enzyme Activity is Critical for Hypoxia Inducible Factor-1α Activity and Provides Novel Targets for Inhibiting Tumor Growth
By Geoffrey Grandjean
Advisory Professor: Garth Powis, D. Phil
Unique to proliferating cancer cells is the observation that their increased need for energy is provided by a high rate of glycolysis followed by lactic acid fermentation in a process known as the Warburg Effect, a process many times less efficient than oxidative phosphorylation employed by normal cells to satisfy a similar energy demand [1]. This high rate of glycolysis occurs regardless of the concentration of oxygen in the cell and …

An Analysis Of The Interaction Of Methylphenidate And Nicotine In Adolescent Rats: Effects On Bdnf, Elizabeth D. Freeman
An Analysis Of The Interaction Of Methylphenidate And Nicotine In Adolescent Rats: Effects On Bdnf, Elizabeth D. Freeman
Electronic Theses and Dissertations
This investigation was an analysis of the interaction of adolescent exposure to methylphenidate (MPH; trade name: Ritalin) on nicotine sensitization and conditioned place preference (CPP) in a rodent model and underlying mechanisms of this effect. Animals were treated IP with 1 mg/kg MPH or saline using a ―school day‖ regimen of five days on, two days off, from postnatal day (P) 28-50. During the final two weeks of MPH treatment, animals were either behaviorally sensitized to nicotine (0.5 mg/kg free base) or saline for 10 days, or conditioned to nicotine or saline using the CPP behavioral paradigm. In addition, three …
The Effect Of Red Maple Leaf Toxicosis On Reduced Glutathione Levels In Equine Erythrocytes In Vitro, Madeline A. Rohl
The Effect Of Red Maple Leaf Toxicosis On Reduced Glutathione Levels In Equine Erythrocytes In Vitro, Madeline A. Rohl
Undergraduate Honors Thesis Projects
Red maple leaf toxicosis is an equine blood disorder resulting from the consumption of wilted red maple (Acer rubrum L.) leaves by horses. Compounds within the leaves of red maple have oxidative effects on equine erythrocytes and can cause hemolysis of erythrocytes, the conversion of hemoglobin to methemoglobin, and the production of Heinz bodies. Reduced glutathione is important in the protection of equine erythrocytes from these oxidative events; however, in the presence of red maple toxin, glutathione is rapidly oxidized and is unavailable. The objective of this study is to determine whether the presence of vitamin C alters levels …
Microbial Communities Of The Providence River, Jacqueline Kratch
Microbial Communities Of The Providence River, Jacqueline Kratch
Honors Projects in Science and Technology
The Providence River has been industrialized for over one-hundred years. Industries such as oil storage and metal recycling facilities have left high levels of pollutant metals, including lead (Pb), in the soil and water. The elevated Pb concentrations in these environments influence the selection of Pb resistance mechanisms in the bacterial community1. One mechanism of heavy metal resistance is the Pb efflux pump, consisting of proteins in the cell membrane that aid in the transport of Pb out of the cell2. In this study we investigated the co-occurrence of Pb efflux pumps and antibiotic efflux pumps in bacteria from Pb …

Current antiretroviral treatments target multiple pathways important for human immunodeficiency virus (HIV) multiplication, including viral entry, synthesis and integration of the DNA provirus, and the processing of viral polyprotein precursors. However, HIV is becoming increasingly resistant to these "combination therapies." Recent findings show that inhibition of HIV Gag protein cleavage into its two structural proteins, matrix (MA) and capsid (CA), has a devastating effect on viral production, revealing a potential new target class for HIV treatment. Unlike the widely used HIV protease inhibitors, this new class of inhibitor would target the substrate, not the protease enzyme itself. This approach offers …
