Systematically Controlling For The Influence Of Age, Sex, Hertz And Time Post-Whole-Body Vibration Exposure On Four Measures Of Physical Performance In Community-Dwelling Older Adults: A Randomized Cross-Over Study, Harold L. Merriman, C. Jayne Brahler, Kurt Jackson

Physical Therapy Faculty Publications

Though popular, there is little agreement on what whole-body vibration (WBV) parameters will optimize performance. This study aimed to clarify the effects of age, sex, hertz, and time on four physical function indicators in community-dwelling older adults (N = 32). Participants were exposed to 2 minutes WBV per session at either 2 Hz or 26 Hz, and outcome measures were recorded at 2-, 20-, and 40-minute post-WBV. Timed get-up-and-go and chair sit-and-reach performances improved post-WBV for both sexes, were significantly different between 2 Hz and 26 Hz treatments (P ≤ 0.05), and showed statistically significant interactions between age and gender …

Chelation Therapy As A Treatment For Autism, Cassandra Baty, Rachel Terharr

Festival of Communities: UG Symposium (Posters)

As medical advances continue to be made, there has yet to be an effectively consistent cure to the commonly known condition, Autism. Some researchers and physicians state that by using chelation therapy, it could help cure mercury poisoning in autistic individuals who were affected by vaccines or other sources. Because of the lack of research and knowledge of chelation therapy, there has been some controversy as to the ethics of providing chelation therapy to autistic children. The families that are put through these trials are faced with high costs, and no guarantee that their child could be cured. But to …

The purpose of this study was to discover the role of traditional Senegalese music used in therapeutic contexts. Specifically, I sought to discover its uses and understand the ideologies and cultural significance behind its usage. I collected data using participant observation, interviewing, and archival research in Dakar and Ngoundiame, a Serrere village, Senegal. I found that music was used for cathartic and healing purposes in two primary schools in Dakar and in the traditional ndepp ceremony, respectively. These usages of music reflected larger themes in Senegalese culture. In conclusion, I recommended that music be integrated into mental health treatment through …

Unifying The Mathematical Modeling Of In Vivo And In Vitro Microdialysis, Peter M. Bungay, Rachita K. Sumbria, Ulrich Bickel

Pharmacy Faculty Articles and Research

A unifying approach is presented for developing mathematical models of microdialysis that are applicable to both in vitro and in vivo situations. Previous models for cylindrical probes have been limited by accommodating analyte diffusion through the surrounding medium in the radial direction only, i.e., perpendicular to the probe axis, or by incomplete incorporation of diffusion in the axial direction. Both radial and axial diffusion are included in the present work by employing two-dimensional finite element analysis. As in previous models, the nondimensional clearance modulus (Θ) represents the degree to which analyte clearance from the external medium influences diffusion through the …

Dietary Interventions Against Mammary Glands And Prostate Cancers, Juliana Adedayo Akinsete

Theses, Dissertations and Capstones

Dietary components modulate normal cellular functions and, in cancer cells, alter processes that lead to cancer and/or its progression. The change in the patterns of human food production and consumption over time has contributed to increasing risk for diseases including cancer. Omega-3 and omega-6 fatty acids are classes of essential polyunsaturated fatty acids in the human diet and are required for normal growth and development. Omega-3 and omega-6 fats are thought to be required in the ratio of 1:1 to 1:4 on which humans are thought to have evolved. However, the Western diet has greatly shifted from this ratio. The …

Knee Range Of Motion: Reliability And Agreement Of 3 Measurement Methods, Paul G. Peters, Michael A. Herbenick, Philip A. Anloague, Ronald J. Markert, L. Joseph Rubino

Physical Therapy Faculty Publications

We conducted a study to compare 3 methods of measuring knee range of motion: visual estimation by physicians, hand goniometry by physical therapists, and radiographic goniometry. We hypothesized that reliability would be high within and across all techniques. We found intrarater and interrater reliability to be satisfactory for visual estimation, hand goniometry, and radiographic goniometry. Interrater reliability across methods did not agree satisfactorily. Between-methods differences in estimating knee range of motion may result from variations in technique among physicians and physical therapists.

Alteplase: The Clot Buster, Mayer Goldberg

The Science Journal of the Lander College of Arts and Sciences

The following is an excerpt from the introduction of this article: The human body is defined by many complex and inconsistent characteristics. For example, the body forms blood clots in traumatic events, but blood clots are likewise associated with hazardous or fatal conditions. Platelets are small cells, derived from the precursor megakaryocytes, which are responsible for blood clotting to prevent bleeding from a ruptured blood vessel. Platelets fasten to each other and release a coagulation factor that solidifies around the ruptured area to prevent blood loss. A subordinate quantity of platelets can result in excessive bleeding. However, high platelet numbers …

Small Intestine Submucosa Effects On Long Term Viability Of Transplanted Pancreatic Cells, Joshua P. Pregnar

PCOM Biomedical Studies Student Scholarship

The biologic functions carried out by the pancreas are, without a doubt, essential to life. This can be demonstrated by the fact that some diabetics require insulin supplementation and those suffering from other diseases of the pancreas, such as pancreatitis, or who have undergone pancreatectomy require supplementation with exocrine enzymes. As would be expected, we are constantly searching for more longterm, patient oriented solutions to chronic health conditions. As such, there has been a gradual transition from daily insulin injections to insulin pumps which allow for easier and more closely controlled glucose levels. Work has also been done regarding various …

A Comparison Of Pharmacist Travel-Health Specialists' Versus Primary Care Providers' Recommendations For Travel-Related Medications, Vaccinations, And Patient Compliance In A College Health Setting, Melissa J. Durham, Jeffery A. Goad, Lawrence S. Neinstein, Mimi Lou

Pharmacy Faculty Articles and Research

Background. Pretravel medication and vaccination recommendations and receipt were compared between primary care providers (PCPs) without special training and clinical pharmacists specializing in pretravel health.

Methods. A retrospective chart review of patients seen for pretravel health services in a pharmacist-run travel clinic (PTC) compared to PCPs at a University Student Health Center. Vaccine/medication recommendations were assessed for consistency with national/international guidelines. Medical/pharmacy records were queried to determine the receipt of medications/vaccinations.

Results. The PTC recommended antibiotics for travelers' diarrhea were given more often when indicated (96% vs 50%, p < 0.0001), and patients seen in the PTC received their medications more often (75% vs 63%, p = 0.04). PCPs prescribed more antibiotics for travelers' diarrhea that were inconsistent with guidelines (not ordered when indicated 49% vs 6%, p < 0.0001 and ordered when not indicated 21% vs 3%, p < 0.0001). The PTC prescribed antimalarials more often when indicated (98% vs 81%, p < 0.0001), while PCPs prescribed more antimalarials that were inconsistent with guidelines (not ordered when indicated 15% vs 1%, p < 0.0001 and ordered when not indicated 19% vs 2%, p < 0.0001). The PTC ordered more vaccines per patient when indicated (mean = 2.77 vs 2.31, p = 0.0012). PTC patients were more likely to receive vaccines when ordered (mean = 2.38 vs 1.95, p = 0.0039). PCPs recommended more vaccines per patient that were inconsistent with guidelines (not ordered when indicated: mean = 0.78 vs 0.12, p < 0.0001, ordered when not indicated: mean 0.18 vs 0.025, p < 0.0001).

Conclusions. A pharmacist-run pretravel health clinic can …

A Comparative Study Of Embedded And Anesthetized Zebrafish In Vivo On Myocardiac Calcium Oscillation And Heart Muscle Contraction, Brian S. Muntean, Christine M. Horvat, James H. Behler, Wissam A. Aboualaiwi, Andromeda M. Nauli, Frederick E. Williams, Surya M. Nauli

Pharmacy Faculty Articles and Research

The zebrafish (Danio rerio) has been used as a model for studying vertebrate development in the cardiovascular system. In order to monitor heart contraction and cytosolic calcium oscillations, fish were either embedded in methylcellulose or anesthetized with tricaine. Using high-resolution differential interference contrast and calcium imaging microscopy, we here show that dopamine and verapamil alter calcium signaling and muscle contraction in anesthetized zebrafish, but not in embedded zebrafish. In anesthetized fish, dopamine increases the amplitude of cytosolic calcium oscillation with a subsequent increase in heart contraction, whereas verapamil decreases the frequency of calcium oscillation and heart rate. Interestingly, verapamil also …

The objective of our study was to compare the effect of two surgical fixation techniques on the motion and biomechanics of the talonavicular joint in a human cadaveric foot model.

Materials and Methods: Thirteen human cadaveric foot specimens were prepared, mounted in a multi-axis programmable robot, and loaded using four loading scenarios. Each of the four loading scenarios consisted of a constant Achilles tendon load of 350N followed by either internal or …

Ruthenium Complexes As Dna Photonucleases In Treatment Of Malignant Skin Carcinoma, Devi Kalyan Karumanchi

All Capstone Projects

A variety of Ruthenium complexes possessing terpyridine complexes as ligands in their coordination sphere have been investigated extensively as DNA photo nucleases in vitro. This work has led to the realization that compounds of Ruthenium bind to DNA purines and that the interactions are of an unprecedented bridging variety. Owing to the molar absorptivity of these complexes in the visible region, direct cleavage of duplex DNA by these complexes requires irradiation in the range of 400-500 nm.

Although the observation of DNA photo cleavage in vitro makes these systems good candidates for further investigation, it does not provide any information …

Boise State University Theses and Dissertations

Introduction: In the last two decades, there has been strong evidence supporting the use of noninvasive ventilation (NIV) in COPD cases. While there are advocates in favor of the use of NIV in patients presented with acute hypoxemic respiratory failure (AHRF) non-related to COPD nor chest trauma, efficacy of NIV in these cases is still heatedly debated in the medical research field.

Objective: To critically assess the existing scientific evidence regarding efficacy of NIV as an adjunct therapy, the endotracheal intubation rate, intensive care and hospital length of stay, fatal complications, and mortality rate in patients presented with AHRF in …

Effect Of Acute Administration Of Angiopoietin-1 In Experimental Traumatic Spinal Cord Injury: Magnetic Resonance Imaging And Neurobehavioral Studies, Chirag B. Patel

Dissertations and Theses (Open Access)

Spinal cord injury (SCI) is a devastating condition that affects people in the prime of their lives. A myriad of vascular events occur after SCI, each of which contributes to the evolving pathology. The primary trauma causes mechanical damage to blood vessels, resulting in hemorrhage. The blood-spinal cord barrier (BSCB), a neurovascular unit that limits passage of most agents from systemic circulation to the central nervous system, breaks down, resulting in inflammation, scar formation, and other sequelae. Protracted BSCB disruption may exacerbate cellular injury and hinder neurobehavioral recovery in SCI.

In these studies, angiopoietin-1 (Ang1), an agent known to reduce …

Mechanism-Based Strategies To Enhance The Actions Of A, Fabiola C. Gomez

Dissertations and Theses (Open Access)

Heat shock protein 90 (HSP90) is an abundant molecular chaperone that regulates the functional stability of client oncoproteins, such as STAT3, Raf-1 and Akt, which play a role in the survival of malignant cells. The chaperone function of HSP90 is driven by the binding and hydrolysis of ATP. The geldanamycin analog, 17-AAG, binds to the ATP pocket of HSP90 leading to the degradation of client proteins. However, treatment with 17-AAG results in the elevation of the levels of antiapoptotic proteins HSP70 and HSP27, which may lead to cell death resistance. The increase in HSP70 and HSP27 protein levels is due …

Characterization And Optimization Of Antigen-Specific T Cell Responses During Ex Vivo Expansion Of Melanoma Tumor-Infiltrating Lymphocytes, Yufeng Li

Dissertations and Theses (Open Access)

Treatment of metastatic melanoma with tumor reactive T cells (adoptive T cell therapy, ACT) is a promising approach associated with a high clinical response rate. However, further optimization of this treatment modality is required to increase the clinical response after this therapy. ACT in melanoma involves an initial phase (pre-REP) of tumor-infiltrating lymphocyte (TIL) expansion ex vivo from tumor isolates followed by a second phase, “rapid expansion protocol” (REP) generating the billions of cells used as the TIL infusion product. The main question addressed in this thesis was how the currently used REP affected the responsiveness of the CD8+ T …

The Use Of Preclinical Models To Improve The Treatment Of Retinoblastoma, Katie Marie Nemeth

Theses and Dissertations (ETD)

Rodent models play an essential role in the development of new chemotherapeutics and dosing regimes. It is often difficult to carryout a clinical study for pediatric cancers due to the small patient population. Retinoblastoma, a pediatric cancer of the eye, is one example of a pediatric cancer that can benefit from preclinical studies. Over the years various retinoblastoma rodent models have been developed used to test various combination of broad-spectrum systemic chemotherapy. It was found form these studies that the combination of topotecan and carboplatin was effective. However both drugs cause myelosuppression and therefore administrating both of these drugs systemically …

Preosteoblast Behavior On A Synthetic Calcium Phosphate Scaffold Coated With Cell Derived Matrix, Daniel A. Young

Theses and Dissertations (ETD)

Bone grafts are commonly used for the treatment of large bone defects. Biodegradable, synthetic bone grafts combined with cells and growth factors as a tissue engineered construct can provide benefits over the common autografts and allografts currently used. Calcium phosphate (CaP) materials offer high biocompatibility and chemical similarity to natural bone tissue. Biodegradable beta-tricalcium phosphate (β-TCP) scaffolds with an interconnected porous network have been created to promote tissue ingrowth and regeneration in vitro and in vivo. Extracellular matrix (ECM) coated on titanium and polymer scaffolds has been shown to improve cell response to those material surfaces. Here, we attempted …

The Effects Of Cellular Theta Breathing Meditation On Cell Mediated Immune Response: A Controlled, Randomized Investigation Of Altered Consciousness And Health, Marjorie D. Hardgrave

UNLV Theses, Dissertations, Professional Papers, and Capstones

Medical anthropology is well positioned to make contributions to consciousness research based on biocultural approaches that integrate methodologies from the biological, behavioral and social sciences to explore aspects of human health. The ubiquity and perseverance of health related activities involving altered states of consciousness (ASC) across cultures past and present suggest that these potentials are deeply rooted in human sociocultural evolution. Analyzing the relationship between immune function and meditative ASC represents an effort to empirically investigate the adaptive value of these human potentials.

A controlled, randomized investigation of two meditation practices was conducted at the University of Nevada, Las Vegas …

Optimization Algorithms For Functional Deimmunization Of Therapeutic Proteins, Andrew S. Parker, Wei Zheng, Karl E. Griswold, Chris Bailey-Kellogg

Dartmouth Scholarship

To develop protein therapeutics from exogenous sources, it is necessary to mitigate the risks of eliciting an anti-biotherapeutic immune response. A key aspect of the response is the recognition and surface display by antigen-presenting cells of epitopes, short peptide fragments derived from the foreign protein. Thus, developing minimal-epitope variants represents a powerful approach to deimmunizing protein therapeutics. Critically, mutations selected to reduce immunogenicity must not interfere with the protein's therapeutic activity.

The Power Of Empowerment: An Icf-Based Model To Improve Self-Efficacy And Upper Extremity Function Of Survivors Of Breast Cancer, Mary Insana Fisher, Dana Howell

Physical Therapy Faculty Publications

Breast cancer is one of the most frequently diagnosed cancers among women. Breast cancer treatments often negatively impact the function of the arm, and quality of life and upper extremity function does not always return to a prediagnosis level. Survivors of breast cancer may also experience feelings of diminished self-efficacy related to functional deficits resulting from their physical limitations. The International Classification of Functioning (ICF) provides a framework for rehabilitation practitioners to address physical and psychological impairments, activity limitations, and participation restrictions. Patient outcomes may be improved by fostering self-efficacy through empowerment. This paper explores how the ICF model and …
