Neurochemical Effects Of Amyloid-Beta Oligomers In Rats, John J. Panos Dec 2010

Neurochemical Effects Of Amyloid-Beta Oligomers In Rats, John J. Panos

Dissertations

Alzheimer’s disease is a progressive neurodegenerative disease characterized by memory loss and cognitive decline. Although the symptomology of Alzheimer’s disease is well defined, its precise etiology remains elusive. Animal models are invaluable for understanding the pathogenesis of this devastating disease. Knowledge of the neurochemical actions of amyloid-β oligomers in specific brain structures is essential for validating animal models of Alzheimer’s disease and for determining the most appropriate behavioral assays of memory. The specific aim of this project was to investigate the neurochemical effects of direct intracerebral infusion of amyloid-β oligomers in the rat. Experiment 1 investigated direct infusions of synthetic …


Effects Of Yellow Rectangular Rapid-Flashing Beacons And Novel Lane Markings On Motorists’ Yielding, Speed, And Headway At Multilane Uncontrolled Crosswalks, Jimmy Wayne Shurbutt Dec 2010

Effects Of Yellow Rectangular Rapid-Flashing Beacons And Novel Lane Markings On Motorists’ Yielding, Speed, And Headway At Multilane Uncontrolled Crosswalks, Jimmy Wayne Shurbutt

Dissertations

Several methods have been examined to increase motorists’ yielding to pedestrians and the distance at which they yield on multilane crosswalks at uncontrolled locations with relatively high average daily traffic (ADT). A series of 5 experiments were conducted to evaluate the efficacy of rectangular rapid-flashing beacons (RRFBs) as effective pedestrian crossing aides. The first experiment found that the RRFBs produced a significant increase in yielding behavior at all 26 sites located in 3 cities in the United States. Data collected over a 2-year follow-up period at 22 of these sites plus 14-month follow-up at an additional 4 sites documented the …


Testing The Efficacy Of A Computerized Behavioral Activation Treatment Of Depressive Disorders, Alyssa H. Kalata Aug 2010

Testing The Efficacy Of A Computerized Behavioral Activation Treatment Of Depressive Disorders, Alyssa H. Kalata

Dissertations

The present study sought to examine the feasibility and preliminary efficacy of a computerized behavioral activation treatment for depressive disorders (IMMBA), while also investigating potential mechanisms of action involved in the treatment of depression through the use of behavioral activation. Nine adults who met criteria for either Major Depressive Disorder or Dysthymic Disorder were recruited from Kalamazoo, Portage, and surrounding areas in Southwestern Michigan. All participants received ten sessions of IMM-BA treatment. Symptoms of depression and related information were assessed at pretreatment and one-week, onemonth, three-month, and six-month follow-up through the use of the Beck Depression Inventory - II (BDI-II), …
