Neuroprotective Effects Of Retinal Ganglion Cells By Specific Alpha 7 Nicotine Acetylcholine Receptor Agonists And An Acetylcholineesterase Inhibitor, Sara Kaliszak Dec 2014

Neuroprotective Effects Of Retinal Ganglion Cells By Specific Alpha 7 Nicotine Acetylcholine Receptor Agonists And An Acetylcholineesterase Inhibitor, Sara Kaliszak

Honors Theses

In previous studies from this lab, an alpha7 nACh receptor was found to successfully modulate retinal ganglion cell neuroprotection against glutamate assault when bound to nicotinic acetylcholine receptors, or if an alpha7 nicotinic acetylcholine agonist, such as PNU-282987 was used in in vitro models (Wehrwein et al., 2004; Iwamoto et al., 2013). These in vitro studies support the hypothesis that activation of alpha7 nicotinic ACh receptors triggers neuroprotection against loss of retinal ganglion cells normally induced by excessive glutamate insult. The results from these in vitro studies instigated an in vivo study in our lab using a rat glaucoma model. …


Visual Impairment And Eye Care Among Older Americans: Secondary Analysis Of The Behavioral Risk Factor Surveillance System (Brfss), Amy L. Freeland Apr 2009

Visual Impairment And Eye Care Among Older Americans: Secondary Analysis Of The Behavioral Risk Factor Surveillance System (Brfss), Amy L. Freeland

Dissertations

The aim of this three-paper format dissertation is to explore three topics relevant to public health and vision loss. The three papers are independent studies, yet build upon each other by first describing the population of people aged 40 years and older in the United States in terms of visual impairment, diagnosed eye disease/injury, and their use of eye care, and then next exploring the factors that influence eye care use for both the general population and the subpopulation of people with diagnosed diabetes. The first paper provides a state-level examination of the characteristics of people aged 40 years and …
