The Effect Of Soleus Fatigue During Sidestep Cutting Maneuvers: Implications For The Acl, Michael William Ciesa

Browse all Theses and Dissertations

The soleus muscle is a monoarticular plantarflexor composed slow-twitch fatigue-resistant muscle fibers. Through its attachment to the proximal tibia, contraction of the soleus muscle in a closed kinetic chain (when the foot is planted) produces a posterior pulling force on the posterior proximal tibia. The anterior cruciate ligament (ACL) is responsible for preventing anterior displacement of the tibia relative to the femur. Through the production of a posterior pulling force on the tibia, soleus muscle contraction in a closed kinetic chain could help reduce strain on the ACL. Fatigue is a neuromuscular phenomenon that can alter biomechanical strategies during athletics …

Wnt Secretion Proteins Modulate Rankl-Induced Expression Of Aire In Thymic Epithelial Cells, Daniel Pollack

Dissertations and Theses

Thymic epithelial cells (TEC) are essential for a proper adaptive immune response by regulating thymocyte development and establishing central tolerance. In the thymus, TECs differentially express Wnt proteins, which activate canonical and non-canonical Wnt signaling pathways. Wnt signaling is thought to regulate cell survival, proliferation, and development although the direct molecular mechanisms in TECs have yet to be elucidated. The inducible inhibition of canonical Wnt signaling with Dkk1 leads to a rapid loss of TEC progenitors as well as a decline in mature Aire-expressing mTECs. Therefore, we explore the role of Wnt ligands potentially responsible for stimulating and/or regulating Wnt …

A Bronchiolitis Study: The Overuse Of Bronchiolitis Therapies In Children Admitted Into The Hospital, Jocelyn S. Canedo

Theses and Dissertations

Bronchiolitis is prevalent among infants of 0 to 12 months, and usually caused by a variation of viruses. Signs and symptoms consist of coughing, rapid breathing, and an occasional fever in some infants. Bronchiolitis is not treated with antibiotics, but rather with proper medical examination and other procedures. Chest radiographs, steroids, and certain bronchodilators are considered ineffective treatments. This study identified the amount of ineffective procedures being used in infants admitted into the pediatric emergency room, and the effect it had on the patient’s average hospital stay. Past medical records were used in this clinical study. Statistical analyses and graphs …

Ccl11 As A Biomarker For The In Vivo Diagnosis Of Chronic Traumatic Encephalopathy, Robert Weissenfels

CMC Senior Theses

Chronic traumatic encephalopathy is the neurodegenerative disease that is ascribed to the long term development of cognitive, behavioral, emotional, and motor deficits as a result of the exposure to high amounts of sub concussive traumatic brain injuries. The disease has gained recent popularity in the media for its prevalence in American football as a response to recent research that has suggested the prominence of the disease in nearly every NFL player that is examined post mortem. This has produced a growing concern for the consequences of head impact and participation in contact sports. Despite media attention, little is currently known …

Radial And Longitudinal Motion Of The Arterial Wall: Their Relation To Pulsatile Pressure And Flow In The Artery, Dan Wang, Linda Vahala, Zhili Hao

Mechanical & Aerospace Engineering Faculty Publications

The aim of this paper is to analyze the radial and longitudinal motion of the arterial wall in the context of pulsatile pressure and flow, and to understand their physiological implications for the cardiovascular system. A reexamination of the well-established one-dimensional governing equations for axial blood flow in the artery and the constitutive equation for the radial dilation of the arterial wall shows that two waves—a pulsatile pressure wave in the artery and a radial displacement wave in the arterial wall—propagate simultaneously along the arterial tree with the same propagation velocity, explaining why this velocity combines the physical properties and …

Exploring Gender Differences Throughout Normal Rat Aging - A Role For Estrogen Signaling In The Brain, Christopher Mark Evola

Browse all Theses and Dissertations

Females are more protected than males from neurodegenerative diseases until they go through menopause when this protection drops dramatically. It has been hypothesized that this neuroprotection is hormone-dependent. The current study characterized cell signaling molecules downstream of estrogen receptor beta that are known to play a role in memory, PKC, ERK, and connexin-43, in regions of the brain associated with memory decline in an attempt to elucidate significant changes that occur post-estrus. Total whole cell lysates were compared to isolated mitochondrial protein because mitochondrial function is known to be altered during aging. As hypothesized, protein concentrations differed depending on age, …

Regulation Of Extra-Pituitary Prolactin In Monocytes And Macrophages, Richard Barrett

Electronic Theses and Dissertations

Recently it has been shown that leukocytes are capable of producing prolactin (PRL). Evidence of extra-pituitary PRL (ePRL) production is so far been limited to primates and is not shared across other mammal species such as mice and rats. While ePRL is characterized as an identical protein to traditional pituitary PRL, it is controlled under an alternative promoter and is thus regulated differently from pituitary PRL. Little is known about what regulates ePRL or its direct role in human physiology, but given that PRL has well over 300 described functions, it is likely that the autocrine and paracrine effects of …

Journal Articles

Postural control and joint position sense are essential for safely undertaking leisure and professional activities, particularly at high altitude. We tested whether exposure to a 12-day trek with a gradual ascent to high altitude impairs postural control and joint position sense. This was a repeated measures observational study of 12 military service personnel (28±4 years). Postural control (sway velocity measured by a portable force platform) during standing balance, a Sharpened Romberg Test and knee joint position sense were measured, in England (113m elevation) and at 3 research camps (3619m, 4600m and 5140m) on a 12-day high altitude trek in the …

Mechanotransduction Signaling In Podocytes From Fluid Flow Shear Stress., Tarak Srivastava, Hongying Dai, Daniel P. Heruth, Uri S. Alon, Robert E. Garola, Jianping Zhou, R Scott Duncan, Ashraf El-Meanawy, Ellen T. Mccarthy, Ram Sharma, Mark L. Johnson, Virginia J. Savin, Mukut Sharma

Manuscripts, Articles, Book Chapters and Other Papers

Recently, we and others have found that hyperfiltration-associated increase in biomechanical forces, namely, tensile stress and fluid flow shear stress (FFSS), can directly and distinctly alter podocyte structure and function. The ultrafiltrate flow over the major processes and cell body generates FFSS to podocytes. Our previous work suggests that the cyclooxygenase-2 (COX-2)-PGE2-PGE2 receptor 2 (EP2) axis plays an important role in mechanoperception of FFSS in podocytes. To address mechanotransduction of the perceived stimulus through EP2, cultured podocytes were exposed to FFSS (2 dyn/cm2) for 2 h. Total RNA from cells at the end of FFSS treatment, 2-h post-FFSS, and 24-h …

UNF Graduate Theses and Dissertations

ABSTRACT

Purpose: The purpose of this study was to examine the relationship between self-reported sedentary time (ST) and the cumulative risk of preserved ejection fraction heart failure (HFpEF) and reduced ejection fraction heart failure (HFrEF) using a diverse cohort of U.S. adults 45-84 years of age.

Methods: Using data from the Multi-Ethnic Study of Atherosclerosis (MESA), we identified 6,814 subjects (52.9% female). All were free of baseline cardiovascular disease. Cox regression was used to calculate the hazard ratios (HR) associated with baseline ST and risk of overall heart failure (HF), HFpEF, and HFrEF. Weekly self-reported ST was dichotomized …

The Role Of A Type Lamins In Regulating Myelination, Jacqueline M. Deloyht

Theses and Dissertations

Multiple sclerosis (MS), a demyelinating disorder of the central nervous system (CNS), affects approximately 400,000 individuals in the United States, and 2.5 million people worldwide. It is a leading cause of disability in young adults. Current treatments for MS target the inflammatory aspects of the disease, but do not aid in remyelination. To address remyelination as a therapeutic strategy, it is imperative to identify mechanisms that regulate myelin formation, including epigenetic targets. In this study, we investigate the role of the LMNA, a gene encoding Lamins A and C, intermediate filaments of the nuclear lamina, in regulating oligodendrocyte development and …

Non-Canonicaly Recruited Tcrαβcd8Αα Iels Recognize Microbial Antigens, Lukasz Wojciech, Edyta Szurek, Michal Kuczma, Anna Cebula, Wessam R. Elhefnawy, Maciej Pietrzak, Grzegorz Rempala, Leszek Ignatowicz

Computer Science Faculty Publications

In the gut, various subsets of intraepithelial T cells (IELs) respond to self or non-self-antigens derived from the body, diet, commensal and pathogenic microbiota. Dominant subset of IELs in the small intestine are TCRαβCD8αα⁺ cells, which are derived from immature thymocytes that express self-reactive TCRs. Although most of TCRαβCD8αα⁺ IELs are thymus-derived, their repertoire adapts to microbial flora. Here, using high throughput TCR sequencing we examined how clonal diversity of TCRαβCD8αα⁺ IELs changes upon exposure to commensal-derived antigens. We found that fraction of CD8αα⁺ IELs and CD4⁺ T cells express identical …

Charecterization Of The Innate Immune Response In The Rat Intervertebral Disc At The Tissue And Cellular Level, Matthew Guerreiro

Theses and Dissertations (Comprehensive)

Low back pain (LBP) affects up to 80% of the global population at some point during their life. The costs associated with LBP are estimated at $100 billion per year, putting significant strains on our healthcare system. As intervertebral disc (IVD) herniation is one of the major causes of LBP we decided to focus on herniation facilitated inflammatory responses, where damage caused by herniation triggers an innate immune response which likely results in pain, inflammation, and recruitment of specialized innate immune cells like macrophages to the affected area. Since the role of the inflammatory response is relatively uncharacterized in the …

Photodermatoses In Children, Siti Nurani Fauziah, Wresti Indriatmi, Lili Legiawati

Journal of General - Procedural Dermatology and Venereology Indonesia

Photodermatoses cover the skin’s abnormal reactions to sunlight, usually to its ultraviolet (UV) component or visible light. Etiologically, photodermatoses can be classified into 4 categories:  (1) immunologically mediated photodermatoses (idiopathic photodermatoses); (2) drug- or chemical-induced photosensitivity; (3) hereditary photodermatoses; and (4) photoaggravated dermatoses. The incidence of photodermatoses in the pediatric population is much lower than in adults, Polymorphous light eruption (PMLE) is the most common form of photodermatoses in children, followed by erythropoietic protoporphyria. Early diagnosis and investigations should be performed to avoid long-term complications. Photoprotection is the mainstay of photodermatoses management, including use of physical protection and sunscreen.

Efficacy Of Topical Estradiol Compared To Topical Glycolic Acid For Skin Aging Treatment In Postmenopausal Women, Shannaz Nada Yusharyahya, Marsha Bianti

Journal of General - Procedural Dermatology and Venereology Indonesia

Skin aging is a complex biological process in human being, as a result from intrinsic factors (genetic, hormonal, metabolism) and extrinsic factors (UV exposure, pollution, smoking, life style). In postmenopausal women, physiologically, the amount of estrogen are decreased, causing deterioration of their skin’s appearance.

Along with the changes that occur, skin care require more attention. A holistic approach can increase epidermal thickness, therefore, reducing the depth of wrinkles, as well as improving skin texture and moisture. There are various treatments available to improve skin appearance due to aging.

This EBCR is aimed to compare the efficacy of topical estradiol and …

Neurofeedback With Fmri: A Critical Systematic Review, Robert T. Thibault, Amanda Macpherson, Michael Lifshitz, Raquel R. Roth, Amir Raz

Psychology Faculty Articles and Research

Neurofeedback relying on functional magnetic resonance imaging (fMRI-nf) heralds new prospects for self-regulating brain and behavior. Here we provide the first comprehensive review of the fMRI-nf literature and the first systematic database of fMRI-nf findings. We synthesize information from 99 fMRI-nf experiments—the bulk of currently available data. The vast majority of fMRI-nf findings suggest that self-regulation of specific brain signatures seems viable; however, replication of concomitant behavioral outcomes remains sparse. To disentangle placebo influences and establish the specific effects of neurofeedback, we highlight the need for double-blind placebo-controlled studies alongside rigorous and standardized statistical analyses. Before fMRI-nf can join the …

Urologist Burnout: Frequency, Causes, And Potential Solutions To An Unspoken Entity, Julie Franc-Guimond, Brian Mcneil, Steven M. Schlossberg, Amanda C. North, Alp Sener

Anatomy and Cell Biology Publications

Physician burnout has been linked to decreased job performance, increased medical errors, interpersonal conflicts, and depression. Recent multispecialty studies suggest that urologists have higher rates (up to 63.6%) of burnout compared to physicians in other specialties; however, these reports were limited by low sample sizes.1 We aimed to evaluate the prevalence of urologist burnout, verify risk factors, and recommend preventative measures and solutions for colleagues at risk or suffering from burnout. Urologist burnout is a true entity that transcends level of training and nationality. Its roots appear to be deep-seated in our tireless efforts to strive for excellence in care …

Acute Resistance Exercise Induces Sestrin2 Phosphorylation And P62 Dephosphorylation In Human Skeletal Muscle, Nina Zeng, Randall F. D'Souza, Vandre C. Figueiredo, James F. Markworth, Llion A. Roberts, Jonathan M. Peake, Cameron J. Mitchell, David Cameron-Smith

Center for Muscle Biology Faculty Publications

Sestrins (1, 2, 3) are a family of stress-inducible proteins capable of attenuating oxidative stress, regulating metabolism, and stimulating autophagy. Sequestosome1 (p62) is also a stress-inducible multifunctional protein acting as a signaling hub for oxidative stress and selective autophagy. It is unclear whether Sestrin and p62^Ser403 are regulated acutely or chronically by resistance exercise (RE) or training (RT) in human skeletal muscle. Therefore, the acute and chronic effects of RE on Sestrin and p62 in human skeletal muscle were examined through two studies. In Study 1, nine active men (22.1 ± 2.2 years) performed a bout of single-leg strength …

Tattoo For Life And Afterlife, Kimberly Chin

Capstones

Man has searched for ways to live forever from time immemorial. But a curious group of tattoo enthusiasts developed a way to preserve one’s tattoo skin (at the least) post-mortem. Here’s a cultural exploration of a small albeit growing trend in which people’s perception of tattoos, burial rites and how to commemorate loved ones is examined and re-examined.

Association Between Left Ventricular Mechanics And Diffuse Myocardial Fibrosis In Patients With Repaired Tetralogy Of Fallot: A Cross-Sectional Study, Christopher M. Haggerty, Jonathan D. Suever, Arichanah Pulenthiran, Abba Mejia-Spiegeler, Gregory J. Wehner, Linyuan Jing, Richard J. Charnigo, Brandon K. Fornwalt, Mark A. Fogel

Biomedical Engineering Faculty Publications

Background: Patients with repaired tetralogy of Fallot (TOF) have progressive, adverse biventricular remodeling, leading to abnormal contractile mechanics. Defining the mechanisms underlying this dysfunction, such as diffuse myocardial fibrosis, may provide insights into poor long-term outcomes. We hypothesized that left ventricular (LV) diffuse fibrosis is related to impaired LV mechanics.

Methods: Patients with TOF were evaluated with cardiac magnetic resonance in which modified Look-Locker (MOLLI) T1-mapping and spiral cine Displacement encoding (DENSE) sequences were acquired at three LV short-axis positions. Linear mixed modeling was used to define the association between regional LV mechanics from DENSE based on regional T1-derived diffuse …
