Distribution And Morphology Of Catecholaminergic Axons And Terminals In Flat-Mounts Of The Whole Left Ventricles Of Rats: Tracing, Digitization And 3d Scaffold, Emily Liu
Honors Undergraduate Theses
Cardiac sympathetic innervation plays a vital role in regulating various heart functions, and its remodeling has been linked to a range of cardiovascular diseases. To understand cardiac sympathetic innervation and remodeling, it is important to elucidate the topographical distribution and morphology of sympathetic axons in the whole left ventricle. However, immunohistochemistry (IHC) on whole heart tissues presents challenges due to their thickness, as conventional methods label only small sections. This disrupts tissue integrity and neural connections. To overcome this, we developed a whole flat-mount technique to process the rat heart (ventricle thickness: 3 mm). We performed cardiac sympathetic nerve imaging …
Comparative Analysis Of Left Ventricular Sympathetic Axons In Shr And Wky Rats, Parker R. Tyson
Comparative Analysis Of Left Ventricular Sympathetic Axons In Shr And Wky Rats, Parker R. Tyson
Honors Undergraduate Theses
Hypertension is a leading cause of cardiovascular morbidity and mortality and is strongly associated with dysregulation of the sympathetic nervous system, which plays a central role in controlling heart rate, vascular tone, and blood pressure. Although increased sympathetic activity has been widely documented in hypertensive disease, the precise structural organization of sympathetic innervation within the hypertensive heart remains incompletely characterized. This study investigates whether chronic hypertension is associated with structural remodeling of sympathetic axons in the left ventricle by comparing autonomic innervation patterns between spontaneously hypertensive rats (SHR) and normotensive Wistar Kyoto rats (WKY). Hearts were collected following transcardial perfusion …
"Star Sign" Of Subarachnoid Hemorrhage, Shivani Ruf
"Star Sign" Of Subarachnoid Hemorrhage, Shivani Ruf
Florida Journal of Emergency Medicine (FJEM)
A 60-year-old female who was brought to the emergency department after a syncopal episode. She was found to have a subarachnoid hemorrhage (SAH) from a ruptured anterior communicating artery aneurysm. Her CT showed the classic "star sign" of SAH.
Health-Outcomes Related To Smartphone Use In The College Student Population: A Scoping Review, Gregory Deglomine
Health-Outcomes Related To Smartphone Use In The College Student Population: A Scoping Review, Gregory Deglomine
Honors Undergraduate Theses
Objective: A scoping review was employed to consolidate what is currently being studied and reported on concerning interactions with smartphone devices and correlated negative health-outcomes, specifically within the college student population. We are specifically concerned with this population due to the unique demands of technology use coupled with free time use of smartphone devices. Information such as study focus, study design, and summarized results are be provided within this compilation of available data. Results: The existing data findings are heavily skewed in favor of a positive correlation between smartphone use and negative health-outcomes. Sampling 17,069 total participants across 41 studies, …
Promotion Of Neuronal Regeneration: Upregulation Of Intrinsic Neuronal Growth Capacity Versus Microtubule Stabilization, Cathy Le
Honors Undergraduate Theses
Central Nervous System (CNS) injury may lead to irreversible damage to cognitive and motor abilities when injured. This is due to the inability of axons to regenerate. This thesis focuses on two methods of promoting axonal regeneration: microtubule stabilization and upregulation of the intrinsic growth capacity of the neuron via the mechanistic target of rapamycin (mTOR) pathway. Both have shown promising results in potentially being a therapeutic treatment for CNS trauma. This research seeks to (1) test a combinatorial method of axonal regeneration utilizing both methods simultaneously and (2) compare microtubule stabilization and upregulation of the mTOR pathway as neuronal …
The Effects Of Matrix Metalloproteinase-9 On Cx3cl1 Shedding And Axon Retraction, Lauren A. Dobrie
The Effects Of Matrix Metalloproteinase-9 On Cx3cl1 Shedding And Axon Retraction, Lauren A. Dobrie
Honors Undergraduate Theses
Spinal cord injury (SCI) often leads to irreversible damage, and permanent paralysis inferior to the injury is common (Leibinger et al., 2013). Injury to the spinal cord occurs in two phases. In the first phase, components of the spinal cord are subject to mechanical trauma causing direct damage. In the second phase, damage spreads from the area of injury through molecular processes. Several studies have linked M1 "pro-inflammatory" macrophages to exacerbation of damage by inducing dieback of dystrophic axons, but not healthy axons, through direct cellular contact. Several studies have identified the presence of macrophage subtypes at specific time. A …
Microscopic Analysis Of Sympathetic And Parasympathetic Distribution, Terminal Morphology, And Interaction In Whole-Mount Atria, Scott Harden
Electronic Theses and Dissertations
The sympathetic (SNS) and parasympathetic (PSNS) branches of the autonomic nervous system (ANS) innervate the heart, exerting excitatory and inhibitory influences (respectively) over cardiac functions (heart rate, AV conduction velocity, and contractility). However, the distribution and structure of SNS and PSNS innervation has not yet been well studied. Detailed characterization of the distributional organization and structural morphology of the SNS and PSNS in normal states is essential to the study of pathological autonomic remodeling. The present study utilized double immunohistochemical labeling techniques to examine tyrosine hydroxylase (TH) immunoreactive (IR) SNS and vesicular acetylcholine transporter (VAChT) IR PSNS axons and terminal …
