Targeting The Cerebrovasculature In Sepsis: A Focus On The Brain Microvascular Endothelium, Divine C. Nwafor Jan 2021

Targeting The Cerebrovasculature In Sepsis: A Focus On The Brain Microvascular Endothelium, Divine C. Nwafor

Graduate Theses, Dissertations, and Problem Reports

The blood-brain barrier (BBB) is a critical interface between the systemic circulation and the brain. It is a specialized multicellular unit composed of brain microvascular endothelial cells (BMECs), pericytes, a basement membrane, and astrocytic end foot processes. BMECs are a principal component of the BBB that provide the structural framework needed for the stringent transport of molecules into the brain. BMEC dysfunction permits the trafficking of neurotoxins from systemic circulation into the brain, which ultimately exacerbates BBB dysfunction and neuroinflammation. Studies have shown that BBB dysfunction is a key determinant of cognitive decline in sepsis. However, there are critical knowledge …


Discrimination And Behavioral Responses To Communication Signals Compared Across Apteronotids., Danielle Leigh Dillon-Seeger Jan 2019

Discrimination And Behavioral Responses To Communication Signals Compared Across Apteronotids., Danielle Leigh Dillon-Seeger

Graduate Theses, Dissertations, and Problem Reports

Sensory systems are often uniquely tailored to encode behaviorally relevant signals and comparative studies across species can thus reveal how evolutionary changes shape sensory functions. The structure of communication signals varies widely between ghost knifefish species. Recent findings suggest that the nervous system co-adapted to the various signal structures observed across species to support different sensory behaviors. The aim for this thesis was to compare the sensory behavior of 3 species of ghost knifefish to contrast their behavioral performance with the known differences in neurophysiology. We hypothesize that for the different signal types and species, the ability to discriminate small …
