Examining The Effects Of Npra Antagonist Anantin On Sci-Induced Ployuria., Lindsey Zipperer Dec 2022

Examining The Effects Of Npra Antagonist Anantin On Sci-Induced Ployuria., Lindsey Zipperer

Electronic Theses and Dissertations

Polyuria, or the over production of urine, is a prevalent condition that significantly impacts the quality of life in individuals suffering from a spinal cord injury (SCI). Post-SCI induced polyuria is thought to have been associated with altered levels of vasopressin (AVP), atrial natriuretic peptide (ANP), and natriuretic peptide receptor A (NPRA). In the present study, the function of NPRA was analyzed in the rat contusion model using anantin, an NPRA antagonist. A daily dose of either 100 µg of anantin or vehicle was administered intraperitoneally immediately following the SCI surgery and continued until termination, 4 weeks post injury (wpi). …


Role Of Meibum And Tear Phospholipids In The Evaporative Water Loss Associated With Dry Eye., Samiyyah M. Sledge Dec 2021

Role Of Meibum And Tear Phospholipids In The Evaporative Water Loss Associated With Dry Eye., Samiyyah M. Sledge

Electronic Theses and Dissertations

It is generally believed that the tear film lipid surface film inhibits the rate of evaporation (Revap) of the underlying tear aqueous. It is also generally believed that changes in the composition of the tear film lipid layer is responsible for an increase in Revap in patients with dry eye. Both of these ideas have never been proven. The purpose of the current studies was to test these ideas. Revap was measured in vitro gravimetrically. Lipid spreading was measured using Raman spectroscopy and microscopy. The influence of the following surface films on the Revap of the sub phase of physiologically …


Medical Schools Ignore The Nature Of Consciousness At Great Cost, Anoop Kumar Jul 2021

Medical Schools Ignore The Nature Of Consciousness At Great Cost, Anoop Kumar

Journal of Wellness

The essential question of the relationship between consciousness and matter is ignored in medical school curricula, leading to a machine-like view of the human being that contributes to physician burnout and intellectual dissatisfaction. The evidence suggesting that the brain may not be the seat of consciousness is generally ignored to preserve the worldview of the primacy of matter. By investigating new frameworks detailing the nature of consciousness at different levels of hierarchy, we can bring intellectual rigor to a once opaque subject that supports a fundamental reality about our experience: We are human beings, not only human bodies.


Examining Neuroanatomical Effects Of Prenatal Valproic Acid And Postnatal Testosterone In A Mouse Model Of Autism Spectrum Disorder, Bishakha Kumari, Elizabeth Ann Gordon, Cynthia Corbitt Jan 2021

Examining Neuroanatomical Effects Of Prenatal Valproic Acid And Postnatal Testosterone In A Mouse Model Of Autism Spectrum Disorder, Bishakha Kumari, Elizabeth Ann Gordon, Cynthia Corbitt

Undergraduate Arts and Research Showcase

Sex differences in Autism Spectrum Disorder (ASD) are well documented; males are diagnosed 4:1 over females. Testosterone (T) is one factor that differs by sex in humans and mice that could increase vulnerability to developing ASD in males. Valproic acid (VPA) is an anticonvulsant that has been found to increase the risk of autism in male offspring of pregnant women who take it to control seizures and is commonly used in mouse models of ASD. After prenatal VPA or vehicle on embryonic day 13, testosterone (T) or vehicle was administered to the mice on postnatal day 2 to investigate whether …


Seen In Science: Lgbtq+ Inclusivity In Anatomy & Physiology Texts, Harshini Sirvisetty, Kat Ray King, Linda Catherine Fuselier Jan 2020

Seen In Science: Lgbtq+ Inclusivity In Anatomy & Physiology Texts, Harshini Sirvisetty, Kat Ray King, Linda Catherine Fuselier

Undergraduate Arts and Research Showcase

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, …


Spinal Cord Injury Induced Cardiac Decline And The Limitations Of Exercise., Kathryn Michele Deveau May 2017

Spinal Cord Injury Induced Cardiac Decline And The Limitations Of Exercise., Kathryn Michele Deveau

Electronic Theses and Dissertations

There is a general consensus that the level and the severity of spinal cord injury (SCI) impacts chronic cardiac abnormalities such that high thoracic and cervical SCI are the most severely affected. Furthermore, the extreme degree of immobility/inactivity experienced by the persons with SCI has implications on cardiac decline. Yet it has been difficult to separate the relative contributions of the decentralized autonomic nervous system (ANS) and the immediate and profound inactivity to chronic cardiac abnormalities. As such, this body of work sought to characterize a contusion SCI that results in persistent CV dysfunction. Echocardiography, Dobutamine stress echocardiography and pressure …


Craniodental Anatomy Of A New Late Cretaceous Multituberculate Mammal From Udan Sayr, Mongolia., Amir Subhash Sheth Aug 2014

Craniodental Anatomy Of A New Late Cretaceous Multituberculate Mammal From Udan Sayr, Mongolia., Amir Subhash Sheth

Electronic Theses and Dissertations

Multituberculates were the longest-lived group of early mammals, with a nearly worldwide distribution, and a temporal range from the Middle Jurassic to the Late Eocene. Multituberculates are typically represented by isolated teeth and jaw fragments; however, several localities in Mongolia revealed abundant, well-preserved multituberculate skulls and partial skeletons from the Late Cretaceous. This study is centered on two specimens of a new multituberculate taxon from a locality in the Gobi desert, Udan Sayr. Included is a (1) bone-by-bone description of the cranial and mandibular elements, as well as the dental features of both specimens, PSS-MAE 141 (holotype) and PSS-MAE 142, …


Effects Of Passive Immobilization On Locomotor Recovery After Spinal Cord Injury In Adult Rats., Kelsey Lee Stipp Aug 2014

Effects Of Passive Immobilization On Locomotor Recovery After Spinal Cord Injury In Adult Rats., Kelsey Lee Stipp

Electronic Theses and Dissertations

Background: Spontaneous locomotor recovery in spinal rats has been attributed to animals moving freely in-cage. Environmental enrichment has been shown to increase in-cage movement and functional recovery subsequently. Anxiety has been shown to decrease overnight activity in rats. Methods: Rats were double-housed in medium cages (MC) or single-housed in tiny sized cages (TC). Slotted dividers allowed for partial isolation in TC. Overnight activity was monitored bi-weekly. The open field test and BBB’s were taken weekly. Gait analysis was performed at weeks six and eight. Results: MC showed higher overnight activity and improved gait overtime. No differences were found in BBB …
