Neurology Faculty Publications

INTRODUCTION: Research-oriented autopsy cohorts provide critical insights into dementia pathobiology. However, different studies sometimes report disparate findings, partially because each study has its own recruitment biases. We hypothesized that a straightforward metric, related to the percentage of research volunteers cognitively normal at recruitment, would predict other inter-cohort differences.

METHODS: The National Alzheimer’s Coordinating Center (NACC) provided data on N = 7178 autopsied participants from 28 individual research centers. Research cohorts were grouped based on the proportion of participants with normal cognition at initial clinical visit.

RESULTS: Cohorts with more participants who were cognitively normal at recruitment contained more individuals who …

The Development And Evaluation Of A Method For Complete Collagenase I Digestion Of Bos Taurus Bone Samples, Reilly Price

Master of Science in Forensic Science Directed Research Projects

Current methods for processing aged forensic bone samples for DNA analysis involve pulverization and organic extraction, which further destroys already degraded DNA and uses large amounts of limited samples. Additionally, the success rates for this type of analysis vary widely as homogenization incorporates PCR inhibitors into the sample. Little research has explored how pulverization results in DNA damage in profiles obtained from skeletal remains. This study proposes an enzymatic digestion method to separate osteocytes from PCR inhibitors in the extracellular bone matrix to improve the quality and quantity of DNA isolated from aged bone samples. The technique described here used …

Opioid System's Potential Involvement In Ketamine's Cognitive And Antidepressant-Like Effects In Rats, Fan Zhang

Theses and Dissertations

Depression stands as one of the most pervasive mental health challenges worldwide, including the United States. Conventional antidepressants typically display a delayed onset of therapeutic action (4-8 weeks) and lack efficacy in a substantial portion of patients (over 40% of depressed patients are treatment-resistant). The dissociative anesthetic ketamine, which is a glutamatergic N-methyl-D-aspartate (NMDA) antagonist, has emerged as a promising novel treatment due to its rapid and prolonged antidepressant effects, and it is especially beneficial for treatment-resistant depression. Nevertheless, the precise neurochemical mechanisms underlying ketamine’s antidepressant properties remain elusive, hampering the development of safer and more efficacious treatments. The present …
