Success Rates Of Second Semester Anatomy Students In Online And On-Ground Classes At A Community College In East Tennessee, William Sproat

Electronic Theses and Dissertations

Educators expect the number of institutions offering online courses and the number of students enrolling in these courses to increase as many students, particularly nontraditional students, discover the advantages of online content delivery. Online courses require new methods of communication between students and faculty as well as discovering new ways to build relationships, earn student trust, conduct appropriate assessment, and deliver useful course content. Many institutions—public, private, and for-profit—offer a wide variety of online coursework but faculty, employers, and the public have expressed concerns about the quality of online course content. In particular, online delivery of coursework in ...


The Effects Of Heart Medication On The Heart Rates Of Drosophila Melanogaster, Felicia A. Baer 2018 Olivet Nazarene University

The Effects Of Heart Medication On The Heart Rates Of Drosophila Melanogaster, Felicia A. Baer

Scholar Week 2016 - present

Background

Current models of human cardiac disease may be similar in anatomy and physiology, but are often expensive and tedious to work with. The current need is for a model organism that is more efficient to work with in lab while still an accurate model of human cardiac disease, of which Drosophila melanogaster (D. mel) is a candidate as it is a more efficient organism to work with in lab. To test whether D. mel could be used as a model for human cardiac disease, the medications atropine and propranolol hydrochloride were used. I hypothesized that atropine and propranolol hydrochloride ...


Immunodeficient R2g2 Mouse Strain Yields Spleens With Unusual Cytoarchitecture And Sympathetic Innervation, Nicholas Mason Britt, Madeleine Kate Miller, Donald B. Hoover Ph.D., John B. Schweitzer M.D. 2018 East Tennessee State University

Immunodeficient R2g2 Mouse Strain Yields Spleens With Unusual Cytoarchitecture And Sympathetic Innervation, Nicholas Mason Britt, Madeleine Kate Miller, Donald B. Hoover Ph.D., John B. Schweitzer M.D.

Appalachian Student Research Forum

The nervous system and immune system contact one another through two-way communication in order to establish and preserve homeostasis. The sympathetic neurotransmitter norepinephrine has an impact on how the immune system responds by affecting regional blood flow and activation of adrenergic receptors on leukocytes. Former studies showed that immune cells are capable of releasing nerve growth factor allowing for the establishment and continuation of sympathetic nerves in targeted tissues. From this gathered information, it was hypothesized that sympathetic nerves would prove to be less frequent in spleens from the immunodeficient R2G2 mouse strain (Envigo) when compared to 129P3/J (129 ...

Anatomy and Regenerative Biology Faculty Publications

Dry Eye disease causes discomfort and pain in millions of patients. Using a mouse acute desiccating stress (DS) model we show that DS induces a reduction in intraepithelial corneal nerve (ICN) density, corneal sensitivity, and apical extension of the intraepithelial nerve terminals (INTs) that branch from the subbasal nerves (SBNs). Topical application of 0.02% Mitomycin C (MMC) or vehicle alone has no impact on the overall loss of axon density due to acute DS. Chronic dry eye, which develops progressively as C57BL/6 mice age, is accompanied by significant loss of the ICNs and corneal sensitivity between 2 and ...


Mechanisms Of Fatigue With Aging: Evidence From The Whole-Limb To The Single Cell In Humans, Christopher W. Sundberg 2018 Marquette University

Mechanisms Of Fatigue With Aging: Evidence From The Whole-Limb To The Single Cell In Humans, Christopher W. Sundberg

Dissertations (2009 -)

Aging is accompanied by a loss of muscle mass and increased fatigability of limb muscles making it difficult for old adults to generate the force and power necessary to perform daily activities, such as ascending a flight of stairs. The mechanisms for the age-related increase in fatigability in old and very old adults (≥80 yrs) and whether there are differences between men and women are unknown. The purpose of this dissertation was to determine the mechanisms for the age-related increase in fatigability in men and women by studying fatigue at the level of the whole-limb and within the muscle cells ...


Comparing Cardiac Dynamics Between Neonatal And Adult Rats, Luther Swift, Rafael Jaimes, Morgan Burke, J Hiebert, Nikki G. Posnack 2018 George Washington University

Comparing Cardiac Dynamics Between Neonatal And Adult Rats, Luther Swift, Rafael Jaimes, Morgan Burke, J Hiebert, Nikki G. Posnack

GW Research Days 2016 - Present

Background:

Cardiovascular physiology studies have been largely limited to adult models; yet, significant developmental differences exist between the immature and adult heart. The field of pediatric research has largely been limited to immortalized cardiomyocyte cell lines, which lack physiologically relevant action potentials, and primary neonatal myocytes that have a limited life span and lack physiologically relevant automaticity. As a result, our understanding of developmental changes in ion channel expression, t-tubule development, and excitation-contraction coupling have been deduced from 2D simplified cell models. To fully understand cardiac development from neonate to adult, a physiologically-relevant 3D whole heart model is needed to ...

Mandatory Multidisciplinary Approach For The Evaluation Of The Lymph Node Status In Rectal Cancer, Marian Diaconescu, Cosmin V. Obleaga, Cecil S. Mirea, Mihai C. Ciorbagiu, Emil Moraru, Ionica D. Vilcea

Journal of Mind and Medical Sciences

Colorectal cancer is the third most frequently reported malignancy and also the third leading cancer-related cause of death worldwide. Lymph node evaluation, both preoperatively and postoperatively, represents an important aspect of the diagnosis and therapeutic strategy in colorectal cancer, such that an accurate preoperative staging is required for a correct therapeutic strategy. Treatment of rectal cancer with positive lymph nodes, a very important predictive prognostic parameter, is currently based on neoadjuvant chemoradiotherapy followed by total/ surgical mesorectal excision and adjuvant regimen.

Preoperative evaluation of the lymph node status in rectal cancer is based on endoscopic ultrasound and magnetic resonance imaging ...

How asymmetries in motor behavior become established normally or atypically in mammals remains unclear. An established model for motor asymmetry that is conserved across mammals can be obtained by experimentally inducing asymmetric striatal dopamine activity. However, the factors that can cause motor asymmetries in the absence of experimental manipulations to the brain remain unknown. Here, we show that mice with inner ear dysfunction display a robust left or right rotational preference, and this motor preference reflects an atypical asymmetry in cortico-striatal neurotransmission. By unilaterally targeting striatal activity with an antagonist of extracellular signal-regulated kinase (ERK), a downstream integrator of striatal ...


Cam Impingement In A Collegiate Male Soccer Player With Bilateral Arthroscopic Labral Repair, Nayun Ahn 2018 University of Nebraska at Omaha

Cam Impingement In A Collegiate Male Soccer Player With Bilateral Arthroscopic Labral Repair, Nayun Ahn

Student Research and Creative Activity Fair

Cam impingement in a collegiate male soccer player with the bilateral arthroscopic labral repair.

To demonstrate cam impingement and recurrent cam deformity caused by femoroacetabular impingement after bilateral arthroscopic labral repair in a collegiate male soccer player. Cam impingement is caused by deformities of the femoral head. The deformity is generated due to overuse and high shear stress on the femoral head leading to restricted hip ROM by grinding the articular cartilage. It is typically detected in young, active male populations playing high-impact sports. In this case, one NCAA Division 1 soccer midfielder reported the recurrent cam impingement after he ...

During neural development, epigenetic modulation of chromatin acetylation is part of a dynamic, sequential and critical process to steer the fate of multipotent neural progenitors toward a specific lineage. Pan-HDAC inhibitors (HDCis) trigger neuronal differentiation by generating an "acetylation" signature and promoting the expression of neurogenic bHLH transcription factors. Our studies and others have revealed a link between neuronal differentiation and increase of mitochondrial mass. However, the neuronal regulation of mitochondrial biogenesis has remained largely unexplored. Here, we show that the HDACi, sodium butyrate (NaBt), promotes mitochondrial biogenesis via the NRF-1/Tfam axis in embryonic hippocampal progenitor cells and neuroprogenitor-like ...

Sandhoff disease, one of the GM2 gangliosidoses, is a lysosomal storage disorder characterized by the absence of beta-hexosaminidase A and B activity and the concomitant lysosomal accumulation of its substrate, GM2 ganglioside. It features catastrophic neurodegeneration and death in early childhood. How the lysosomal accumulation of ganglioside might affect the early development of the nervous system is not understood. Recently, cerebral organoids derived from induced pluripotent stem (iPS) cells have illuminated early developmental events altered by disease processes. To develop an early neurodevelopmental model of Sandhoff disease, we first generated iPS cells from the fibroblasts of an infantile Sandhoff disease ...


Enucleated Cells Reveal Differential Roles Of The Nucleus In Cell Migration, Polarity, And Mechanotransduction, Gunes Uzer 2018 Boise State University

Enucleated Cells Reveal Differential Roles Of The Nucleus In Cell Migration, Polarity, And Mechanotransduction, Gunes Uzer

Mechanical and Biomedical Engineering Faculty Publications and Presentations

The nucleus has long been postulated to play a critical physical role during cell polarization and migration, but that role has not been defined or rigorously tested. Here, we enucleated cells to test the physical necessity of the nucleus during cell polarization and directed migration. Using enucleated mammalian cells (cytoplasts), we found that polarity establishment and cell migration in one dimension (1D) and two dimensions (2D) occur without the nucleus. Cytoplasts directionally migrate toward soluble (chemotaxis) and surface-bound (haptotaxis) extracellular cues and migrate collectively in scratch-wound assays. Consistent with previous studies, migration in 3D environments was dependent on the nucleus ...

A 36 -year old woman IV drug abuser admitted with Right-Sided Infective Endocarditis (RSIE) as demonstrated by transthoracic echocardiogram. Patient was admitted 8 weeks later with recurrence of symptoms, moreover signs of systemic embolization were noted. Transthoracic and Transesophageal Echocardiograms revealed tricuspid valve vegetation, severe tricuspid regurgitation, left atrial mass, Patent Foramen Ovale (PFO), severely dilated right atrium and prominent Chiari's network. Systemic embolization included brain and Left iliacus abscesses. Patent Foramen ovale is the proposed mechanism leading to extensive systemic embolization in the present case.

3D scaffold-based in vitro cell culturing is a recent technological advancement in cancer research bridging the gap between conventional 2D culture and in vivo tumours. The main challenge in treating neuroblastoma, a paediatric cancer of the sympathetic nervous system, is to combat tumour metastasis and resistance to multiple chemotherapeutic drugs. The aim of this study was to establish a physiologically relevant 3D neuroblastoma tissue-engineered system and explore its therapeutic relevance. Two neuroblastoma cell lines, chemotherapeutic sensitive Kelly and chemotherapeutic resistant KellyCis83 were cultured in a 3D in vitro model on two collagen-based scaffolds containing either glycosaminoglycan (Coll-GAG) or nanohydroxyapatite (Coll-nHA ...

Human Induced Rotation And Reorganization Of The Brain Of Domestic Dogs, Taryn Roberts, Paul McGreevy, Michael Valenzuela 2018 University of Sydney

Human Induced Rotation And Reorganization Of The Brain Of Domestic Dogs, Taryn Roberts, Paul Mcgreevy, Michael Valenzuela

Paul McGreevy, Ph.D.

Domestic dogs exhibit an extraordinary degree of morphological diversity. Such breed-to-breed variability applies equally to the canine skull, however little is known about whether this translates to systematic differences in cerebral organization. By looking at the paramedian sagittal magnetic resonance image slice of canine brains across a range of animals with different skull shapes (N = 13), we found that the relative reduction in skull length compared to width (measured by Cephalic Index) was significantly correlated to a progressive ventral pitching of the primary longitudinal brain axis (r = 0.83), as well as with a ventral shift in the position of ...
