Genes that establish the circadian clock have differential expression with respect to solar time in central and peripheral tissues. Here, we find circadian-time-induced differential expression in a large number of genes not associated with circadian rhythms in two brain regions lacking overt circadian function: the dorsal vagal complex (DVC) and the central nucleus of the amygdala (CeA). These regions primarily engage in autonomic, homeostatic, and emotional regulation. However, we find striking diurnal shifts in gene expression in these regions of male Sprague Dawley rats with no obvious patterns that could be attributed to function or region. These findings have implications …

Sleep-Wake Disturbances In Mild Traumatic Brain Injury: Meta Analysis Of Literature And Modeling Of Cerebral Tissue Vulnerability, Xiangfu Zhang, Subhendra Sarkar, Mary A. Browne
Publications and Research
Sleep disturbance is a frequent complaint for patients with mild traumatic brain injury (mTBI), it can prolong recovery, and the oxidative stress from lack of sleep could worsen other secondary damages of mTBI. The common types of sleep disturbance of mTBI include insomnia, daytime sleepiness, and obstructive sleep apnea. Conventional imaging often fails to detect any abnormalities in mTBI, and the etiology of sleep disturbance is still unclear. Based on the analysis of current published neurobiological and imaging literature, multiple factors could play a role leading to sleep disturbance in mTBI, however, we have focused on the diencephalon, melatonin and …
Catabolic Degradation Of Endothelial Vegfa Via Autophagy, 2020 Thomas Jefferson University
Catabolic Degradation Of Endothelial Vegfa Via Autophagy, Thomas Neill, Carolyn Chen, Simone Buraschi, Renato V. Iozzo
Department of Pathology, Anatomy, and Cell Biology Faculty Papers
Extracellular matrix-evoked angiostasis and autophagy within the tumor microenvironment represent two critical, but unconnected, functions of the small leucine-rich proteoglycan, decorin. Acting as a partial agonist of vascular endothelial growth factor 2 (VEGFR2), soluble decorin signals via the energy sensing protein, AMP-activated protein kinase (AMPK), in the autophagic degradation of intracellular vascular endothelial growth factor A (VEGFA). Here, we discovered that soluble decorin evokes intracellular catabolism of endothelial VEGFA that is mechanistically independent of mTOR, but requires an autophagic regulator, paternally expressed gene 3 (PEG3). We found that administration of autophagic inhibitors such as chloroquine or bafilomycin A1, or depletion …
Gut Pathophysiology In Mouse Models Of Social Behavior Deficits, 2020 East Tennessee State University
Gut Pathophysiology In Mouse Models Of Social Behavior Deficits, Kyla Scott
Undergraduate Honors Theses
Autism spectrum disorders (ASD) encompass neurodevelopment disorders characterized by atypical patterns of development that impact multiple areas of functioning beginning in early childhood. The etiology of ASD is unknown and there are currently no preventative treatment options. Gastrointestinal symptoms are commonly associated comorbidities. The microbiota-gut-brain axis is a multidirectional communication chain that connects the central and enteric nervous system that relates brain function to peripheral intestinal functions. Changes within this axis have been postulated in ASD. For example, the “leaky gut theory” proposes that chronic inflammation is linked to alterations in the bacterial profiles of the gut microbiome and subsequent …

Biology is unique from other science disciplines in that concepts taught in core classes can inform our student’s understanding of sex and gender. A biology major encounters lessons on sex determination, sexual reproduction, and sex characteristics in their courses. The language used in these units matters. It is imperative that educators consider how the language, examples, and content that we use in classrooms drive (or not) inclusivity for gender- and sexuality-diverse (GSD) (aka LGBTQ+) individuals. We chose to analyze four college-level human anatomy/physiology (AP) textbooks for GSD population inclusivity. We adopted a queer theory framework to critically examine how sex, …

The Quantified Elf, Umico Niwa
Theses and Dissertations
The Quantified Elf is an ongoing collection of scientific, medical, archaeological articles and excerpts from my personal journal. It is a way by which I explore the various ways Western notions of personhood subsume human life into constructs of sexuality and gender, overlooking the various other modes of unbridled existence: plant, microbial. fungal, animal, celestial bodies. The speculative medical papers propose novel forms of body modification to combat gender dysphoria.

Whereas the diagnosis of moderate and severe traumatic brain injury (TBI) is readily visible on current medical imaging paradigms (magnetic resonance imaging [MRI] and computed tomography [CT] scanning), a far greater challenge is associated with the diagnosis and subsequent management of mild TBI (mTBI), especially concussion which, by definition, is characterized by a normal CT. To investigate whether the integrity of the blood-brain barrier (BBB) is altered in a high-risk population for concussions, we studied professional mixed martial arts (MMA) fighters and adolescent rugby players. Additionally, we performed the linear regression between the BBB disruption defined by increased gadolinium contrast …

BACKGROUND: Medulloblastoma (MB) is one of the most common malignant cancers in children. MB is primarily classified into four subgroups based on molecular and clinical characteristics as (1) WNT (2) Sonic-hedgehog (SHH) (3) Group 3 (4) Group 4. Molecular characteristics used for MB classification are based on genomic and mRNAs profiles. MB subgroups share genomic and mRNA profiles and require multiple molecular markers for differentiation from each other. Long non-coding RNAs (lncRNAs) are more than 200 nucleotide long RNAs and primarily involve in gene regulation at epigenetic and post-transcriptional levels. LncRNAs have been recognized as diagnostic and prognostic markers in …
Combination Of Investigational Cell-Based Therapy And Deep Brain Stimulation To Alter The Progression Of Parkinson’S Disease, 2020 University of Kentucky
Combination Of Investigational Cell-Based Therapy And Deep Brain Stimulation To Alter The Progression Of Parkinson’S Disease, Nader El Seblani
Theses and Dissertations--Pharmacy
Parkinson’s disease (PD) is the second most common neurodegenerative disorder and the motor symptoms are caused by progressive loss of midbrain dopamine neurons. There is no current treatment that can slow or reverse PD. Our current “DBS-Plus” clinical trial (NCT02369003) features the implantation in vivo of autologous Schwann cells (SCs) derived from a patient’s sural nerve into the substantia nigra pars compacta (SNpc) in combination with Deep Brain Stimulation (DBS) therapy for treating patients with advanced PD.
The central hypothesis of our research is that transdifferentiated SCs within conditioned nerve tissue will deliver pro-regenerative factors to enhance the survival of …

Corpus Cavernosum Abscess Secondary To Traumatic Perforation Of Urethral Diverticulum, Thomas C. Gore, Anna Schepcoff, Domenick Sorresso
West Florida Division Virtual Research Day 2020
A corpus cavernosum abscess is a rare condition. Usual etiologies include penile injection of erectile dysfunction medications or illicit drugs, priapism, sexually transmitted infections, and trauma; however, there have been reported cases of idiopathic etiology. The most common causative organisms include Staphylococcus aureus, Streptococci, and Bacteroides [1]. Diagnosis is typically made clinically and through imaging (computed tomography [CT] and ultrasound). The first-line treatment is the use of intravenous (IV) antibiotics and surgical drainage. More conservative treatment, however, includes aspiration in conjunction with IV antibiotics [2-3]. Urethral diverticulum (UD) is the formation of a saccular outpouching of the urethral lumen. Symptoms …

ABSTRACT
Introduction: Anterior Cruciate Ligament (ACL) injuries are an upsetting setback for many athletes that require a long and costly recovery process. The injury rates are four times greater in women than men. Preventative measures that help to prevent ACL injuries are limited to stretching and strengthening. Therefore, this review aims to investigate if oral contraceptive [I] usage provides a possible new avenue for prevention of ACL injury [O] in young female athletes (ages 18-30) [P] compared to those that do not take oral contraceptives [C].
Methods: A literature review was performed though PubMed, Google Scholar, SCOPUS Database, and ClinicalKey …

Peer Reviewed Articles
Brown adipose tissue undergoes a dynamic, heterogeneous response to cold exposure that can include the simultaneous synthesis, uptake, and oxidation of fatty acids. The purpose of this work was to quantify these changes in brown adipose tissue lipid content (fat-signal fraction (FSF)) using fat-water magnetic resonance imaging during individualized cooling to 3 °C above a participant’s shiver threshold. Eight healthy men completed familiarization, perception-based cooling, and MRI-cooling visits. FSF maps of the supraclavicular region were acquired in thermoneutrality and during cooling (59.5 ± 6.5 min). Brown adipose tissue regions of interest were defined, and voxels were grouped into FSF decades …

While GM1 may interact with α-synuclein in vitro to inhibit aggregation, the ability of GM1 to protect against α-synuclein toxicity in vivo has not been investigated. We used targeted adeno-associated viral vector (AAV) overexpression of human mutant α-synuclein (A53T) in the rat substantia nigra (SN) to produce degeneration of SN dopamine neurons, loss of striatal dopamine levels, and behavioral impairment. Some animals received daily GM1 ganglioside administration for 6 weeks, beginning 24 hours after AAV-A53T administration or delayed start GM1 administration for 5 weeks beginning 3 weeks after AAV-A53T administration. Both types of GM1 administration protected against loss of SN …

Decomposition Of Pig Carcasses At Varying Room Temperature, Jacqueline Abad Santos
Themis: Research Journal of Justice Studies and Forensic Science
The goal of this study is to assess the qualitative scoring of decomposition scales with statistical analysis while also determining which indoor environment will decompose the fastest. When comparing the three indoor environments, water decomposition appears to be the fastest, but the method of analysis for this study determines that using decomposition scales to analyze such environments may produce statistically insignificant results. For this study, piglets were put in a dry steel tub, a water filled steel tub, and a suitcase. These were recorded using photographs for 25 days and then scored using decomposition scales. The total score was divided …

Our work aims to connect and model multiple small, inter-related tissue injuries as a consequence of mild traumatic brain injuries (mTBI). It has been shown that frontal and temporal lobes are vulnerable regions for brain traumatic injury. A brain injury from a blow or high-speed impact can cause undersurface of the frontal and temporal lobes to deform against the anterior and cranial fossae. This deformation can often trigger damage to the cerebral vasculature, which is ill-understood and can result in chronic damage to larger vessels over time. These physiological injuries can be manifested psychologically; such as patients’ sleep-wake disturbances. The …
