Inhibition Of Bruton Tyrosine Kinase Reduces Neuroimmune Cascade And Promotes Recovery After Spinal Cord Injury, Chen Guang Yu, Vimala Bondada, Hina Iqbal, Kate L. Moore, John C. Gensel, Subbarao Bondada, James W. Geddes
Physiology Faculty Publications
Microglia/astrocyte and B cell neuroimmune responses are major contributors to the neurological deficits after traumatic spinal cord injury (SCI). Bruton tyrosine kinase (BTK) activation mechanistically links these neuroimmune mechanisms. Our objective is to use Ibrutinib, an FDA-approved BTK inhibitor, to inhibit the neuroimmune cascade thereby improving locomotor recovery after SCI. Rat models of contusive SCI, Western blot, immunofluorescence staining imaging, flow cytometry analysis, histological staining, and behavioral assessment were used to evaluate BTK activity, neuroimmune cascades, and functional outcomes. Both BTK expression and phosphorylation were increased at the lesion site at 2, 7, 14, and 28 days after SCI. Ibrutinib …

There are functional benefits to exercise in muscle, even when performed late in life, but the contributions of epigenetic factors to late-life exercise adaptation are poorly defined. Using reduced representation bisulfite sequencing (RRBS), ribosomal DNA (rDNA) and mitochondrial-specific examination of methylation, targeted high-resolution methylation analysis, and DNAge™ epigenetic aging clock analysis with a translatable model of voluntary murine endurance/resistance exercise training (progressive weighted wheel running, PoWeR), we provide evidence that exercise may mitigate epigenetic aging in skeletal muscle. Late-life PoWeR from 22–24 months of age modestly but significantly attenuates an age-associated shift toward promoter hypermethylation. The epigenetic age of muscle …

The purpose of this study is to determine Doctor of Pharmacy students’ emotional responses and coping precipitated by the COVID-19 pandemic, and the influence of media use, working status, and participation in hobbies. …
The Role Of Neuronal Atp-Sensitive Potassium Channels In Learning And Memory, Shaul Vladimir Yahil
The Role Of Neuronal Atp-Sensitive Potassium Channels In Learning And Memory, Shaul Vladimir Yahil
Arts & Sciences Electronic Theses and Dissertations
ATP-sensitive potassium (KATP) channels link cellular metabolism and membrane excitability in many tissues, including brain and pancreas. Gain-of-function (GOF) mutations to KATP channels cause neonatal diabetes, with some patients exhibiting developmental delay, epilepsy, and neonatal diabetes (DEND) syndrome. Diabetic symptoms have been attributed to loss of membrane excitability and insulin secretion in pancreatic β-cells, though the origin of neurological deficits and the effects of neuronal KATP-GOF mutations more generally remain elusive. In this dissertation, I will present evidence that mice expressing KATP-GOF mutations pan-neuronally (nKATP-GOF) demonstrated sensorimotor and cognitive deficits, whereas hippocampus-specific hKATP-GOF mice exhibited predominantly learning and memory deficits. …

Many of the molecular and cellular mechanisms discovered to regulate skeletal muscle hypertrophy were first identified using the rodent synergist ablation model. This model reveals the intrinsic capability and necessary pathways of skeletal muscle growth in response to mechanical overload (MOV). Reminiscent of the rapid cellular growth observed with cancer, we hypothesized that in response to MOV, skeletal muscle would undergo metabolic programming to sustain increased demands to support hypertrophy. To test this hypothesis, we analyzed the gene expression of specific metabolic pathways taken from transcriptomic microarray data of a MOV time course. We found an upregulation of genes involved …
Ketone Body Metabolism In The Ischemic Heart, Stephen C. Kolwicz Jr.
Ketone Body Metabolism In The Ischemic Heart, Stephen C. Kolwicz Jr.
Health and Exercise Physiology Faculty Publications
Ketone bodies have been identified as an important, alternative fuel source in heart failure. In addition, the use of ketone bodies as a fuel source has been suggested to be a potential ergogenic aid for endurance exercise performance. These findings have certainly renewed interest in the use of ketogenic diets and exogenous supplementation in an effort to improve overall health and disease. However, given the prevalence of ischemic heart disease and myocardial infarctions, these strategies may not be ideal for individuals with coronary artery disease. Although research studies have clearly defined changes in fatty acid and glucose metabolism during ischemia …

Role Of Ataxia Telangiectasia Mutated Kinase In Western-Type Diet-Induced Cardiac Outcomes Under Basal And Ischemic Conditions, Mary Wingard
Role Of Ataxia Telangiectasia Mutated Kinase In Western-Type Diet-Induced Cardiac Outcomes Under Basal And Ischemic Conditions, Mary Wingard
Electronic Theses and Dissertations
Ataxia-telangiectasia mutated kinase (ATM), a serine/threonine kinase, plays a role in DNA damage repair, redox sensing, and metabolism. In the heart, ATM contributes significantly in the myocardial infarction (MI)-induced cardiac remodeling with effects on fibrosis, hypertrophy, apoptosis and inflammation. This study investigates the role of ATM deficiency in 14 weeks Western-type diet (WD)-induced cardiac outcomes prior to and 1-day post-MI in a sex-specific manner using wild-type (WT) and ATM heterozygous knockout (hKO) mice. In male mice, ATM deficiency induced rapid body weight gain and preload-associated dysfunction, while WT mice displayed afterload-associated dysfunction 14 weeks post-WD. Myocyte apoptosis and hypertrophy were …
Role Of Meibum And Tear Phospholipids In The Evaporative Water Loss Associated With Dry Eye., Samiyyah M. Sledge
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 …

Acute Consumption Of A Sugar-Sweetened Beverage Impairs Microvascular Function In Midwestern Hispanic Males, Emma Hirshman, Anne R. Crecelius
Health and Sport Science Faculty Publications
Hispanic males are at risk for cardiovascular disease and consume high levels of sugar-sweetened beverages (SSB); yet, their acute vascular response to SSBs is unknown. Ten healthy Hispanic men (18-45 years old) consumed a SSB and reactive hyperemia was performed prior to, immediately following, and 1-hr post-consumption. Both peak and total (area under the curve) forearm blood flow were attenuated immediately following consumption but returned to at or above pre-consumption levels at the 1-hr test.

Complex tissue regeneration is extremely rare among adult mammals. An exception, however, is the superior tissue healing of multiple organs in spiny mice (Acomys). While Acomys species exhibit the remarkable ability to heal complex tissue with minimal scarring, little is known about their cardiac structure and response to cardiac injury. In this study, we first examined baseline Acomys cardiac anatomy and function in comparison with commonly used inbred and outbred laboratory Mus strains (C57BL6 and CFW). While our results demonstrated comparable cardiac anatomy and function between Acomys and Mus, Acomys exhibited a higher percentage of cardiomyocytes displaying …

Moving In Fluid: Exploring How Fishes Manipulate Water To Swim Efficiently, Nils B. Tack
Moving In Fluid: Exploring How Fishes Manipulate Water To Swim Efficiently, Nils B. Tack
USF Tampa Graduate Theses and Dissertations
Moving through a dense fluid such as water presents some unique challenges to minimizing energy use and maximizing performance (i.e., speed). Due to animal-fluid interactions during swimming (drag and thrust production) fish have evolved a variety of morphological structures and locomotor mechanisms. For instance, fish rely on body bending and/or fins to interact with the surrounding water such that energy can be transferred to generate thrust. Typically, this synergy promotes morphologies and behaviors aimed at enhancing propulsive efficiency and/or minimizing metabolic activity to lessen the cost of transport (COT). This work focuses on quantifying the energetic and hydromechanical benefits of …

Fibroblast Growth Factor 19 Increases The Excitability Of Pre-Motor Glutamatergic Dorsal Vagal Complex Neurons From Hyperglycemic Mice, Jordan B. Wean, Bret N. Smith
Physiology Faculty Publications
Intracerebroventricular administration of the protein hormone fibroblast growth factor 19 (FGF19) to the hindbrain produces potent antidiabetic effects in hyperglycemic mice that are likely mediated through a vagal parasympathetic mechanism. FGF19 increases the synaptic excitability of parasympathetic motor neurons in the dorsal motor nucleus of the vagus (DMV) from hyperglycemic, but not normoglycemic, mice but the source of this synaptic input is unknown. Neurons in the area postrema (AP) and nucleus tractus solitarius (NTS) express high levels of FGF receptors and exert glutamatergic control over the DMV. This study tested the hypothesis that FGF19 increases glutamate release in the DMV …

Creating Reel Designs: Reflecting On Arthrogryposis Multiplex Congenita In The Community, Iris Layadi
Purdue Journal of Service-Learning and International Engagement
Because of its extreme rarity, the genetic disease arthrogryposis multiplex congenita (AMC) and the needs of individuals with the diagnosis are often overlooked. AMC refers to the development of nonprogressive contractures in disparate areas of the body and is characterized by decreased flexibility in joints, muscle atrophy, and developmental delays. Colton Darst, a seven-year-old boy from Indianapolis, Indiana, was born with the disorder, and since then, he has undergone numerous surgical interventions and continues to receive orthopedic therapy to reduce his physical limitations. His parents, Michael and Amber Darst, have hopes for him to regain his limbic motion and are …

Body Composition Assessment In Masters Level Swimmers, Megan E. Larson, Amy Morgan, Jessica Kiss, Mary-Jon Ludy
International Journal of Aquatic Research and Education
Body composition of collegiate swimmers has been extensively studied; however, there are limited reports of body composition among Masters swimmers. This study compared the accuracy of air displacement plethysmography (ADP) and bioelectrical impedance (BIA) to the gold standard method of underwater weighing (UWW) in Masters level swimmers. The relationship between percent body fat (%BF) and body mass index (BMI) was also assessed. Recruitment (n = 6 females, 11 males) occurred at two Masters swim clubs. Pearson correlation coefficients revealed no significant differences between ADP, BIA, and UWW (p > 0.05). For both female and male Masters swimmers, the mean %BF …

It is a highly prevalent disease worldwide with approximately 915,000 individuals living with it in Ireland. Support is vital and it is important that individuals in college have a good understanding of disabilities. Previous studies found that there is a lack of knowledge and awareness about rheumatic diseases amongst the general public, however, no studies focused on the student population.
Aim: To investigate students’ knowledge and perception of arthritis and to determine whether education and more awareness about arthritis is needed amongst students.
Methods: This was …
A Literature Review On The Development Of Upper Limbs In Humans, Anh T. Phan
A Literature Review On The Development Of Upper Limbs In Humans, Anh T. Phan
The Cardinal Edge
The development of tetrapod upper limbs shares an evolutionary origin and has been adapted and specialized for different functions for different species, such as flight in birds, swimming and balance in sea mammals, and coordination and grabbing objects in humans. The basis of tetrapod limb development has common developmental patterns, starting with the formation of the limb bud via Sonic hedgehog (Shh) signaling, where later developmental steps are modified for specialized functions. This review covers the basic developmental patterns of mammalian tetrapod development seen in humans, beginning with the formation of the limb bud, to the axis development of the …

Do Water Safety Lessons Improve Water Safety Knowledge?, Michael J. Tipton, Joseph Muller, Cristian Abelairas Gomez, Jo Corbett
International Journal of Aquatic Research and Education
A person, usually a child or young adult, dies by drowning every 90 seconds around the planet. Most drowning prevention initiatives do not assess the efficacy of the intervention. In this study, thirteen- to fourteen-year-olds had their level of water safety knowledge (covering cold shock, rips and tides) assessed before, just after, and 3-6 months after one, 25-minute water safety lesson on these topics. We evaluated the knowledge gained and retained on water safety “awareness” (i.e., knowledge of risks) and “confidence” in terms of knowing what to do in an emergency. The results demonstrated that the lesson significantly increased water …
