Identification And Characterization Of The Expression Profile Of Oligodendrocyte-Derived And Associated Proteins Via Unilateral X-Irradation Of The Rat Optic Nerve, Nicholas Greco
Theses and Dissertations
Recent studies examining cell-cell interactions during CNS development and following disease or trauma have highlighted our limited understanding of the in vivo functions of the myelinating cell of the CNS, the oligodendrocyte. With this in mind, our laboratory has developed techniques by which a profile of proteins derived from or regulated by oligodendrocytes can be elucidated. Specifically, we have demonstrated that oligodendrocytes can be selectively eliminated from one optic nerve of a rat by treating the animal with a unilateral exposure of X-irradiation at the time of birth. Consequently, this approach allowed us to experimentally create, within the same animal, …

Magic Mountain, Diana Al-Hadid
Magic Mountain, Diana Al-Hadid
Theses and Dissertations
My installations are propositions for an imaginary world that relies on its own internal logic, a world of believability without recognition. While the work references landscape it also emphasizes its contrivance, as it is automatically estranged in an "unnatural" gallery setting. I subvert or de-familiarize the materials and processes that I use in the service of creating a fictitious environment. My places are impossible places. They are irregular, illogical, and unstable. Our imagination can be one of most dangerous things to psychological stability as it is an inventory of all things possible, no matter how irrational or improbable. The irrational …

Long-Term Cardioprotection With Phosphodiesterase-5 Inhibition Against Ischemia-Reperfusion Injury: Role Of Nitric Oxide., Vladimir Paul Daoud
Theses and Dissertations
Recent studies have shown that the potent phosphodiesterase-5 (PDE-5) inhibitor, sildenafil citrate, induces a powerful cardioprotective effect against ischemia-reperfusion (I/R) injury in rabbit and mouse hearts. However, the effect of this drug in inducing long-term protection against I/R injury remains unknown. The goal of this study was to identify the duration of the protective window of sildenafil citrate as well as vardenafil, a more potent PDE-5 inhibitor. Rabbits were treated with sildenafil (0.7 mg/kg, iv), vardenafil (0.143 mg/kg), or an equivalent volume of saline. After 24 hrs, 48 hrs, 96 hrs, or 7 days of sildenafil treatment, the hearts were …

Novel Strategies In Cardioprotection Against Ischemia/Reperfusion Injury, Fadi N. Salloum
Theses and Dissertations
Cell damage represents a major pathomechanism in many diseases of high clinical interest, such as myocardial infarction (MI), where it plays an important role in ischemia-reperfusion (I/R) injury. Considerable progress has been made towards identifying physiological and pharmacological agents that play a key role in myocardial preconditioning against I/R injury and also elucidating the molecular changes leading to such protection.Second messengers in cellular signaling pathways, such as cGMP have been well implicated as key players in ischemic and pharmacological preconditioning (PC) of the heart. Phosphodiesterase type 5 (PDE-5) is an enzyme that specifically hydrolyzes cGMP thereby decreasing its tissue concentration. …
