Donor Age Effects On The Proliferative And Chondrogenic/Osteogenic Differentiation Performance Of Equine Bone Marrow- And Adipose Tissue Derived Mesenchymal Stem Cells In Culture, Jasmin Bagge

Theses and Dissertations--Veterinary Science

Orthopedic injuries are a major cause of lameness and morbidity in horses. Bone marrow (BM)- and adipose tissue (AT) derived mesenchymal stem cells (MSCs) have shown potential to facilitate the repair of orthopedic injuries and are being used increasingly in veterinary clinics. Presently, the use of MSCs as a therapy for equine patients is most commonly applied as autologous transplants, using BM- and AT-MSCs harvested from the patient shortly after the time of injury. Cell-based therapies are therefore delayed to enable primary cell numbers to be expanded in culture. Of concern, however, are human and rodent studies that have shown …

Host-Parasite Interaction In Horses: Mucosal Responses To Naturally Acquired Cyathostomin Infections And Anthelmintic Treatment, Ashley Elaine Steuer

Theses and Dissertations--Veterinary Science

Cyathostomins are ubiquitous parasites in equids. In rare cases, cyathostomins lead to a generalized typhlocolitis and death. In healthy horses, local reactions are noted to the mucosal larvae; however, the mechanisms and importance of these reactions have not been elucidated. It has been hypothesized that anthelmintics can alter these reactions. Currently, three drug classes are approved for use in horses against cyathostomins; while all products target the adults, only two products are labeled as larvicidal. Adulticidal therapy is implicated in triggering the typhlocolitis, however, current evidence is contradictory. There is also conjecture that the larvicidal drugs can increase the risk …

Comparative Chondrogenesis Of Interzone And Anlagen Cells In Equine Skeletal Development, Chanhee Mok

Theses and Dissertations--Veterinary Science

At the presumptive sites of future synovial joints during mammalian skeletogenesis, articular cartilage develops from interzone located between the cartilaginous anlagen of bones. Thus, two types of cartilaginous tissues differentiate in close proximity. While anlagen cartilage is transient, progressing through endochondral ossification to form bones, articular cartilage is stable and functions throughout life to facilitate both low friction movement and load distribution. Despite important life-long functional properties, articular cartilage has a very limited intrinsic ability to repair structural defects. On the other hand, structural lesions in bones generally heal well by forming a cartilaginous callus and recapitulating endochondral ossification to …

Stress And Cancer Treatment: How A Family’S Adaptability And Cohesion Affects Financial Stress, Emily Marie Johnson

Theses and Dissertations--Family Sciences

According to the American Cancer Society (2019), it is estimated that 1,762,450 new cancer diagnoses occurred in 2019 in the United States. Currently, cancer remains one of the leading causes of death worldwide (American Cancer Society, 2019). As cancer affects the family, roles within the family will shift (e.g., transitioning to a caregiving relationship), causing each family member to adapt. With the costs of cancer steadily increasing, this potentially leaves a devastating impact on the family. When considering family function in terms of Family Systems, John Rolland created the Family Systems Illness Model to explain how families adapt to an …

Risk factors, including exposure to environmental pollutants, poor dietary and overall health outcomes, and low environmental health literacy (EHL), place the rural Appalachian youth population at increased risk for chronic diseases. Implementation of nutrition and pollution curriculum into two week-long summer day camps for youth ages 5-12 years that focus around healthy lifestyles and environmental stewardship has the potential to increase health protective action in this community. This research utilized qualitative interviews of 30 Kids on the Creek Camp attendees to determine the efficacy of the implementation of an active learning lesson to increase EHL by explaining the link between …

Appetite-Regulating Hormones In Energy Compensation With Exercise, Jack Moreland

Theses and Dissertations--Nutrition and Food Systems

Background: The appetite-regulating hormones may influence compensatory increases in energy intake with exercise, although this causal relationship has been difficult to prove in a longitudinal trial.

Methods: 37 participants (29 female) aged 18 to 40 years performed aerobic exercise 6 days (6d), 2 days (2d), or 0 days per week for 12-weeks. Concentrations of ghrelin, leptin, glucagon-like peptide 1 (GLP-1), and insulin were assessed before (fasting, minute 0) and after a standardized meal at minute 15, 30, 45, 60, 90, 120, 150, and 180. Linear mixed-effects models were used to model the relationships between time point (12 weeks vs. baseline) …

Cardiac Effects Of Obesity During Pregnancy In C57bl/6j Mice, Kayla Lynn Dudick

Theses and Dissertations--Nutrition and Food Systems

Objective: Pregnancy requires profound cardiac and metabolic adaptation. Left ventricular (LV) mass is increased in response to pregnancy, but is not associated with cardiac damage. In contrast, obesity-mediated cardiac hypertrophy is pathological. Data from animal studies indicate dietary fatty acid composition may have a protective effect during states of extreme cardiac physiological adaptation. In contrast, aberrant cardiac metabolism is a hallmark of disease. Over a third of reproductive-age women in the United States are obese, but there is a paucity of data describing the effect of obesity on maternal cardiac adaptation to pregnancy. The objective of this study was to …

Is Postural Control During Unstable Sitting A Proxy Measure For Determinants Associated With Lumbar Stability?, Christian Larivière, Richard Preuss, Daniel Ludvig, Sharon M. Henry

Études primaires

Abstract

The aim of this study was to test whether determinants associated with lumbar stability can predict performance during unstable sitting (trunk postural control - TPC). If confirmed, unstable sitting could be viewed as a proxy measure for these determinants. Wobbling chair motion was measured in 58 subjects with an inertial sensor, and six outcomes were computed (mean frequency and velocity, frequency dispersion, two variables from the sway density analysis and Lyapunov exponent - short interval) to represent TPC performance. Subjects also performed five other trunk neuromuscular tests to quantify the thickness of back and abdominal muscles and …

Theoretical Investigation Of The Low Frequency Fundamental Mechanism Of The Objective Occlusion Effect Induced By Bone-Conducted Stimulation, Kevin Carillo, Olivier Doutres, Franck Sgard

Études primaires

The objective occlusion effect induced by bone-conducted stimulation refers to the low frequency acoustic pressure increase that results from occluding the ear canal opening. This phenomenon is commonly interpreted as follows: the bone-conducted sound “leaks” through the earcanal opening and is “trapped” by the occlusion device. This instinctive interpretation misrepresents the fundamental mechanism of the occlusion effect related to the earcanal impedance increase and already highlighted by existing electro-acoustic models. However, these models simplify the earcanal wall vibration (i.e., the origin of the phenomenon) to a volume velocity source which, in the authors' opinion, (i) hinders an exhaustive comprehension of …

Physiological Effects During Aerobatic Flights On Science Astronaut Candidates, Pedro Llanos, Diego M. Garcia

Publications

Spaceflight is considered the last frontier in terms of science, technology, and engineering. But it is also the next frontier in terms of human physiology and performance. After more than 200,000 years humans have evolved under earth’s gravity and atmospheric conditions, spaceflight poses environmental stresses for which human physiology is not adapted. Hypoxia, accelerations, and radiation are among such stressors, our research involves suborbital flights aiming to develop effective countermeasures in order to assure sustainable human space presence. The physiologic baseline of spaceflight participants is subject to great variability driven by age, gender, fitness, and metabolic reserve. The objective of …

Main contribution: Inconsistent correlations were found between objective and subjective outcome measures. The strongest outcome measure …

Promoting A Culture Of Civility Among Oncology Nurses In The Ambulatory Care Setting To Improve Patient Safety And Nurse Retention, Sheila Evans

DNP Scholarly Projects

INTRODUCTION: Nurse incivility is a well-documented phenomenon discussed in the literature and woven into the nursing lexicon. Nurse incivility results in negative consequences for nurses, patients and organizations. Adding to its complexity is the fact that nurses may be unable to identify and address covert uncivil behaviors and lack an effective tactic to mitigate situations.

AVAILABLE KNOWLEDGE: The nursing literature describes the existence of nurse-to-nurse incivility and its correlation with negative outcomes. Regulatory bodies such as The Joint Commission (TJC) also recognize the adverse outcomes resulting from civility and issued two alerts addressing workplace behavior. Additionally, the American Nurses Association …

Using The Bedside Care Conference To Improve The Patient Experience, Eileen Keefe

DNP Scholarly Projects

Abstract

Improving the patient experience of hospital care is a priority for nursing leaders. The terms patient satisfaction and patient experience have been used interchangeably to define the patient’s unique perspective on care quality and the impact of patient engagement on health outcomes. Patients and families experience suffering when their expectations are not congruent with their care in the hospital setting, and there are significant cost and financial implications for organizations that do not reach performance thresholds. Communication with nurses is highly correlated to overall patientsatisfaction in the Center for Medicare and Medicaid (CMS) Hospital Consumer Assessment of Providers and …
