A Multiple Input Multiple Output Framework For The Automatic Optical Fractionator-Based Cell Counting In Z-Stacks Using Deep Learning, Palak Dave

USF Tampa Graduate Theses and Dissertations

Quantifying cells in a defined region of biological tissue is critical for many clinical and preclinical studies, especially in pathology, toxicology, cancer, and behavior. Unbiased stereology is the state-of-art method for quantification of the total number and other morphometric parameters of stained objects in a defined region of biological tissue. As part of a program to develop accurate, precise, and more efficient automatic approaches for quantifying morphometric changes in biological tissue, our group has shown that both deep learning-based and hand-crafted algorithms can estimate the total number of histologically stained cells at their maximal profile of focus in extended depth …

Possibilities Of Using Neuromarketing Tools In The Hospitality Industry, Serdar Bulbul

University of South Florida (USF) M3 Publishing

Usage of neurosciences in social sciences has emerged new perspectives and methods for marketing and tourism marketing. Neuro-marketing and Neuro-tourism are some of those concepts. In the hospitality industry, marketing is in a complex state because the decision-making processes of the guests are unpredictable. For this reason, hotel managements are unable to satisfy guest’s requests and demands with traditional methods. Therefore, Neuro-marketing has importance because this new way of marketing has a high chance to replace currently used methods. Usage of Neuro-marketing in the hospitality industry could satisfy the guest requests while generating new marketing perspectives on hotel management. This …

Reelin Supplementation For The Rescue Of Fragile X Syndrome., Nicole K. Morrill

USF Tampa Graduate Theses and Dissertations

Reelin is a large, extracellular matrix glycoprotein involved in neuronal migration during embryonic brain development and synaptic plasticity in the adult brain. Reelin consists of eight EGF-like repeats and undergoes natural cleavage at two sites, between repeats 2 and 3 and repeats 5 and 6, resulting in five naturally occurring fragments. The role of Reelin in the developing central nervous system has been extensively characterized, and loss of Reelin or disruption in the signaling cascade may contribute to the cognitive impairments seen in numerous neurodevelopmental or aging diseases such as schizophrenia, autism, depression, epilepsy, and Alzheimer’s disease. Reelin’s signaling potentiates …

Noninvasive In Vivo Optoacoustic Imaging Of Alcohol Use Disorder Using A Mouse Model Of Alcohol Use Disorder, Augustine Meombe Mbolle

USF Tampa Graduate Theses and Dissertations

This research has two parts. The first part focuses on the use of photoacoustic imaging (PAI) to study alcohol-induced effects in the cerebral vasculature of selectively bred alcohol-preferring mice. Part two extends the application of PAI by developing a novel Photoacoustic imaging guided system for repetitive low intensity focused ultrasound (PAI-LIFU) stimulation treatment for alcohol use disorder in crossed high alcohol preferring (cHAP) mice.

Photoacoustic imaging is an emerging hybrid non-invasive optical imaging modality which relies on optical absorption contrast to visualize deep tissue structures and function. It combines the high contrast associated with pure optical imaging and the high …

Small Heat Shock Protein 22 Preserves Neuronal Function In A Murine Model Of Tauopathy, Santiago Rodriguez Ospina

USF Tampa Graduate Theses and Dissertations

Proteinopathies is a family of diseases associated with the pathological aggregation of protein. There are a multitude of proteinopathies, like tauopathy and synucleinopathy that contribute to neurodegenerative diseases like Alzheimer’s disease (AD), Creutzfeldt-Jakob, Pick’s disease, Frontotemporal dementia, and Parkinson’s disease (PD). Currently, one focus of research in the field is mitigating aggregation-prone proteins contributing to disease state. One method of targeting aggregation is the use of chaperones. Chaperones are molecular machinery that help maintain homeostasis in the cells, through various roles and mechanisms, one of those methods is to regulate protein aggregation. Chaperones can achieve this by affecting protein-protein interactions, …

Impact Of Arginine Metabolism And Sensing In Mouse Models Of Alzheimer’S Disease, Chao Ma

USF Tampa Graduate Theses and Dissertations

Alzheimer’s disease (AD) remains the most common neurodegenerative disease in the central nervous system (CNS), with amyloidosis and tauopathy as their two main hallmarks. Typical AD pathologies include cerebral plaques deposited by amyloid-β, neurofibrillary tangles aggregated by tau, and neuroinflammation caused by activated brain myeloid cells. A critical theme is centered on impaired brain metabolism. Emerging evidence showed that impaired arginine metabolism was a novel biomarker pathway for AD. The manipulation of arginine metabolism by a critical enzyme arginase 1 (ARG1) in neurons indicated therapeutic benefits in alleviating tau pathology. Balanced cellular proteostasis was governed by the mechanistic target of …

Investigations Into The Improvement Of Angelman Syndrome Therapeutics, Austin W. Nenninger

USF Tampa Graduate Theses and Dissertations

Angelman syndrome (AS) is a rare genetic neurodevelopmental disease caused by interruption of the function of the ubiquitin ligase UBE3A gene. Patients experience an early life onset of symptoms which include pronounced intellectual disability, drastic speech impairmentor inability to speak, severe movement disorders, seizures, aggression, disruptive sleep impairment, and unusual personality traits. Estimates of prevalence show that approximately 1:15000 births are affected.

The disease is severe, and the burden can be devastating to the patients and the caregivers that they require for the duration of their relatively normal lifespan. Current treatments for the disease are lacking. Many are expensive and …
