New Paradigms In The Treatment Of Acute Complicated And Uncomplicated Type B Aortic Dissection, Eric S. Weiss

Aurora Heart Failure / Transplant Faculty

The treatment of acute type B aortic dissection is a rapidly evolving field, due in a large part to the advent of thoracic endovascular aortic repair (TEVAR). This review will summarize the current literature on the management of both complicated and uncomplicated type B dissections, with special attention paid to emerging evidence supporting earlier aggressive treatment.

Microgravity Exerts An Age-Dependent Effect On Cardiovascular Progenitor Cell Development, Jonathan Baio

Loma Linda University Electronic Theses, Dissertations & Projects

The heart and its cellular components are profoundly altered by missions to space and injury on Earth. Increasing evidence has identified that one such alteration induced by spaceflight is the promotion of the efficacious use of stem cells in therapies on Earth. For this reason, neonatal and adult human cardiovascular progenitor cells (CPCs) were cultured aboard the International Space Station (ISS). Subsequently, we assessed the effects of mechanical unloading on developmental properties and signaling. Spaceflight induced the expression of genes that are typically associated with an earlier state of cardiovascular development. In particular, in neonatal CPCs, we measured increased expression …

Spinal Cord Trauma: An Overview Of Normal Structure And Function, Primary And Secondary Mechanisms Of Injury, And Emerging Treatment Modalities, Daniel Morin

Senior Honors Theses

The structures of the spinal cord and vertebral column are designed to provide flexibility, while still providing ample protection for the spinal cord deep within. While it does offer remarkable protection against most routine trauma, the spinal cord is still vulnerable to high-force etiologies of trauma and may become damaged as a result. These events are referred to as primary injury. Following the initial injury, the body’s own physiological responses cause a cascade of deleterious effects, known as secondary injury. Secondary injury is a major therapeutic target in mitigating the effects of spinal cord injury (SCI), and much research is …

Thalamocortical Processing Of Temporal Cues In Sounds, Kasey Smith

Honors Scholar Theses

The ability of the brain to extract meaningful information from complex sounds is what allows mammals to understand species-specific communication as well as important environmental cues such as the sound of water or of potential predators or prey. The auditory cortex of humans and other mammals contains multiple cortical regions that unique sensitivities to both spectral and temporal sound cues. This discourse will explore three main factors proposed to determine these distinct processing capabilities in regard to temporal sound cues; the distribution of glutamate transporters in the thalamus, the architecture of afferent pathways between the thalamus and auditory cortex, and …

Functional Anatomy Of Palmar Musculature, Colin W. Moore

Electronic Thesis and Dissertation Repository

The palmaris longus (PL) and palmaris brevis (PB) are upper limb muscles considered atavistic remnants of those found in animal species. Despite their use in surgical grafting and tendon transfer procedures, the functional role of the PL and PB have not been investigated comprehensively in vivo. Using a multi-modal experimental approach consisting of indwelling fine wire electromyography (EMG), ultrasonography and immunohistochemical muscle staining techniques, the function of the PL and PB in the hand was evaluated both in in vivo and in situ.

The purpose of Study 1 was to determine whether the PL provides synergistic contributions to …

Effects Of Load Carriage And Surface Inclination On Linear And Non-Linear Postural Variability, Rahul Soangra, Hema Bhatt, Ehsan Rashedi

Physical Therapy Faculty Articles and Research

Understanding of inclined-work-related risk of falls and developing novel practical engineering controls for reducing this risk of falls among hilly working population remains in high demand. Standing on sloped surfaces provides a unique environment for examining the biomechanics and neural control of standing. The present investigation examined the variability of postural signals when standing on inclined surfaces and with load carriages by linear and nonlinear analysis. The purpose of this study was to determine if the sloped surface deteriorated in postural stability among healthy individuals with two distinctive kinds of load carriage methods head versus posterior load carriage. We also …

A Comparison Of Hamstring Injury Recovery Rates In Male And Female Athletes, Amanda Hall

Undergraduate Honors Theses

Excerpt from Introduction

Hamstring injuries are among the most common muscular injuries sustained by athletes across multiple levels of various sports (Askling et al). Most hamstring injuries occur during similar movements and under similar conditions, where the muscle is required to be explosive. Thus, athletes that participate in sports where “sprinting, kicking, or high-speed skilled movements” are required, experience an increased likelihood of suffering a hamstring injury (Erickson and Sherry). After injury, athletes are then subjected to different methods of rehabilitation to heal and strengthen the afflicted area. However, some athletes take longer than others to return and impatience may …
