Analgesia Followed By Long-Term Hyperalgesia Generated By Disinhibition Of The Basolateral Amygdala, Derek Atchley
Analgesia Followed By Long-Term Hyperalgesia Generated By Disinhibition Of The Basolateral Amygdala, Derek Atchley
Wayne State University Theses
Stress produces bimodal effects on pain peception. During exposure to a stressor pain responses are inibited (i.e. stress-induced analgesia). However, following long-term exposure to a stressor increases in responsiveness to painful stimuli may develop (i.e. stress-induced hyperalgesia). Here I evaluated how a key component of the subcortical defense circuit and target of stress hormones contributes to the development of both stress-induced analgesia and hyperalgesia. Bicuculline methiodide, a GABAA antagonist, injected into the basolateral amygdala was used to mimic the neural effects of a stressor or threat exposure. Immediately following injection pain responsiveness was decreased as measured by vocalizations after discharge …
Histological Evidence Of The Effect Of Oil Palm Phenolics In Atherogenic Diet Induced Rat Model Of Alzheimer’S Disease, Kenechukwu Monplaisir Monplaisir
Histological Evidence Of The Effect Of Oil Palm Phenolics In Atherogenic Diet Induced Rat Model Of Alzheimer’S Disease, Kenechukwu Monplaisir Monplaisir
Wayne State University Theses
BACKGROUND: Alzheimer’s disease (AD) is a neurodegenerative disease with the clinical presentation of memory loss and cognitive impairment. Alzheimer's disease pathology is the accumulation of beta amyloid plaques and neurofibrillary tangles.
METHOD: In this study atherogenic diet was used to induce AD in aged Brown Norway rats. The rats were assigned to the following four groups fed isocaloric diets; control group (C ),high cholesterol diet (H), high cholesterol + oil palm phenolics group (HP), high cholesterol + curcumin group (HC). The impact of oil palm phenolics (OPP) on neuronal health and its effect on amyloid deposition was evaluated using histology …
Development Of A Financial Decision-Making Self-Efficacy Measure For Older Adults, Evan Gross
Development Of A Financial Decision-Making Self-Efficacy Measure For Older Adults, Evan Gross
Wayne State University Theses
Financial decision-making is important for older adults, and many are at increased risk for elder financial exploitation due to a combination of biological, social, and psychological factors. The role of self-efficacy for financial decision-making in this population has received little attention from researchers, but evidence suggests it may be a critical aspect in motivating positive decisions and avoiding exploitation. This study developed the Financial Decision-Making Self-Efficacy Scale (FDMSES) for older adults. Participants (N = 200, mean age = 71.5) completed the Lichtenberg Financial Decision-Making Rating Scale (LFDRS) and a neuropsychological test battery. Items from the LFDRS related to financial decision-making …
Higher Statistical Uncertainty With Small Pixel Sizes Gives Higher Pass Rates., Kurt William Van Delinder
Higher Statistical Uncertainty With Small Pixel Sizes Gives Higher Pass Rates., Kurt William Van Delinder
Wayne State University Theses
Monte Carlo (MC) based dose calculation methods trade-off accuracy at the expense of computational time, which is, correlated to the user input values of statistical uncertainty and pixel spacing (1). It was first hinted by low et. al. that noise generated within either the calculated or measured plan distributions can affect the result of the plan verification by method of ‘Gamma Index Analysis’(GI) (2). The purpose of this research experiment is to investigate a possible correlation between added noise from increasing MC statistical uncertainty and increasing the odds of a plan passing the GI verification criteria. For this research experiment, …
