Effects Of Exercise On Parkinson's Symptom Relief, Brooke Burnett
Effects Of Exercise On Parkinson's Symptom Relief, Brooke Burnett
The Eleanor Mann School of Nursing Undergraduate Honors Theses
In this review of twenty research articles, the effects of moderate exercise therapy on the symptoms of Parkinson’s Disease will be explored. Appropriate literature was located using the research question, “In older adults with a Parkinson’s Disease Diagnosis, how does moderate exercise influence the symptoms of this disease?” Twenty peer-reviewed research articles were examined for the impact of different forms of exercise on various symptoms associated with Parkinson’s. Nineteen of the articles reviewed provide substantial evidence in support of exercise therapy as a treatment option for people with Parkinson’s, and one of the articles found inconclusive evidence neither in support …
Influence Of Heating And Biological Sex On Vascular Dysfunction Associated With Long-Duration Sitting And Standing, Aaron Richard Caldwell
Influence Of Heating And Biological Sex On Vascular Dysfunction Associated With Long-Duration Sitting And Standing, Aaron Richard Caldwell
Graduate Theses and Dissertations
Purpose: The purpose of these studies was to determine if arterial angulations (through sitting or standing), shear stress (through local heating), or a combination of these factors affected vascular function. Moreover, this studied estimated the magnitude of the effect that biological sex has on these vascular responses. Methods: Twenty-six healthy, young (18-40 years old) males (n=13) and females (n=13) completed two experimental trials (2-h sitting and 2-h standing). In a randomized fashion, one leg was passively heated in order to increase shear rate. Following a 48-h washout, participants returned to the laboratory to complete the other trial. Flow-mediated dilation (FMD) …
In-Vitro Simulation Of Acute Ischemic Stroke, Paolo Garcia
In-Vitro Simulation Of Acute Ischemic Stroke, Paolo Garcia
Biomedical Engineering Undergraduate Honors Theses
Acute ischemic stroke (AIS) is a condition that involves the occlusion of a blood vessel within the brain, effectively preventing the passage of oxygen and nutrients. AIS is highly prevalent in the United States, where nearly 795,000 strokes happen per year and 87% of those are ischemic. From a medical standpoint, the obstructing clot can be removed with the use of a stroke retrieval device. However, a need arises for testing the aforementioned devices on a patient’s specific vascular geometries in order to increase the likelihood of a successful procedure. Outlined is a process for developing a physical simulation of …
The Use Of Cortisol And Hba1c As Biomarkers Of Stress In University Administrators, Jacilyn Marie Olson
The Use Of Cortisol And Hba1c As Biomarkers Of Stress In University Administrators, Jacilyn Marie Olson
Graduate Theses and Dissertations
PURPOSE: The purpose of this study was to explore the impact of perceived stress and cardiorespiratory fitness on cortisol and HbA1c, biomarkers of stress, in a group of select university administrators. The impact of gender on these relationships was of special concern. METHODS: University administrators with job titles of Chancellor, Provost, Vice Chancellors and Vice Provosts of the university, and Deans and Associate Deans at the college level were recruited. Twenty-five administrators (15 males and 10 females) agreed to participate and completed a battery of assessments that included completion of the University Administrative Concerns Questionnaire, a finger-stick blood test for …
Electrostatic Charge Polarity Effect On Respiratory Deposition In The Glass Bead Tracheobronchial Airways Model, Mohammed Ali, Malay K. Mazumder, Rama N. Reddy, Mariofanna Milanova, Jing Zhang, Alexandru S. Biris
Electrostatic Charge Polarity Effect On Respiratory Deposition In The Glass Bead Tracheobronchial Airways Model, Mohammed Ali, Malay K. Mazumder, Rama N. Reddy, Mariofanna Milanova, Jing Zhang, Alexandru S. Biris
Journal of the Arkansas Academy of Science
The effects of unipolar and bipolar electrostatic charges on the deposition efficiency of therapeutic aerosols in the physical model of human tracheobronchial (TB) airways have been investigated. Respirable size aerosol particles were generated by a commonly prescribed and commercially available nebulizer and charged by a corona charger and then their size and charge distributions were characterized by an Electronic Single Particle Aerodynamic Relaxation Time analyzer to study the drug aerosol particles' deposition pattern. The experiments were performed with a glass bead tracheobronchial model (GBTBM) (physical model) which was designed and developed based upon widely used and adopted dichotomous lung morphometric …

Effect Of Charge On The Deposition Of Electrostatically Charged Inhalable Aerosol In Lung Model, Divey Saini, C. U. Yurteri, N. Grable, Robert A. Sims, Malay K. Mazumder
Journal of the Arkansas Academy of Science
Inhalable drugs are widely used for treating lung diseases such as asthma, emphysema, and cystic fibrosis. The aerosol particles in these inhalable drugs may be charged electrostatically. The deposition of these inhaled therapeutic aerosol particles in the different regions of the lung depends on the particle aerodynamic diameter, electrostatic charge distribution, particulate number density, breathing rate, aerodynamics of the lung, ambient temperature, and relative humidity (RH). The primary mechanisms for lung deposition of inhaled particles are impaction, gravitational settling, diffusion, interception, and electrostatic attraction. To simulate lung deposition, electrostatically charged aerosol particles are introduced through a throat section into a …
