Health Promoting Self-Care: Evaluating The Impact Of Food And Fitness Challenge On The Physical And Psychological Health Of Healthcare Workers, Giancarlo Lyle-Edrosolo, Gena Oppenheim, Emily Enos, Marlon G Saria
2022 Southern California Nursing Research Conference
Background: The unprecedented rates of burnout, stress, and turnover amongst healthcare workers following the COVID-19 pandemic highlighted the importance of prioritizing caregiver physical and mental health. Despite a direct correlation between nurses with multiple health problems and turnover intention, literature searched over the last two decades yielded minimal results using terms such as, nurses and diet, fitness or exercise therapy. A recent study, which focused on female nurses, found an improvement in psychological health by addressing diet, while another found a decrease in occupational stress with an aerobics program. There is even less data to support the use of a …

Pathophysiology of Aortic Stenosis
Proper evaluation of co-morbidities is imperative for patient safety and successful outcomes for patients undergoing anesthesia. Aortic stenosis (AS) is one of the most complex diseases encountered in anesthesia, affecting five percent of older adults and ten percent of the 80-89-year-old-cohort (Joseph et al., 2017). The pathophysiological development of AS is the end result of an inflammatory process caused by endothelial damage from mechanical stress, …

Introduction
Thyroid crisis is a rare and life-threatening endocrine emergency characterized by exaggerated clinical manifestations of hyperthyroidism with cardiovascular manifestations being the most severe. Rhythm disturbances, sinus tachycardia and atrial fibrillation, are the commonest cardiac manifestations of severe thyrotoxicosis; however, asystole remains a very atypical and uncommon presentation. We present a case of thyrotoxicosis due to Grave’s disease complicated by multiple episodes of asystole.
Case Presentation
A 65-year-old female recently diagnosed with Grave’s disease presented to the hospital with recurrent episodes of syncope. Her hospital course was significant for atrial fibrillation with subsequent progression to sinus pauses and asystole spontaneously …

Medical Student Research Symposium
During tumor progression, lysosome function is often maladaptively upregulated to match the high energy demand required for cancer cell hyper-proliferation and invasion. Here, we report that mucolipin TRP channel 1 (TRPML1), a lysosomal Ca2+ and Zn2+ release channel that regulates multiple aspects of lysosome function, is dramatically upregulated in metastatic melanoma cells compared with normal cells. TRPML-specific synthetic agonists (ML-SAs) are sufficient to induce rapid (within hours) lysosomal Zn2+-dependent necrotic cell death in metastatic melanoma cells while completely sparing normal cells. ML-SA-caused mitochondria swelling and dysfunction lead to cellular ATP depletion. While pharmacological inhibition or genetic silencing of TRPML1 in …

Cardiac resident macrophages facilitate electrical conduction by interacting with cardiomyocytes via connexin-43 (Cx43) hemichannels. Cx43 is critical for impulse propagation and coordination between muscle contractions. Cardiomyocyte electrophysiology can be altered when coupled with noncardiomyocyte cell types such as M2c tissue-resident macrophages. Using cocultures of murine HL-1 cardiomyocytes and RAW 264.7 macrophages, we examined the hypothesis that cytokine signals, TGF-β1 and IL-10, upregulate Cx43 expression at points of contact between the two cell types. These cytokine signals maintain the macrophages in an M2c anti-inflammatory phenotype, mimicking cardiac resident macrophages. The electrophysiology of cardiomyocytes was examined using di-8-ANEPPS potentiometric dye, which reflects …

Modulating Cardiac Remodeling After Myocardial Infarction, Upendra Chalise
Theses & Dissertations
Cardiac remodeling after myocardial infarction (MI) is indicated by infarct wall thinning, reduced ejection fraction, and dilation of the left ventricle (LV). Inflammation presides in the early days of MI as a key event in cardiac wound healing. Infiltration of inflammatory cells, predominantly neutrophils and macrophages, is stimulated by ischemic cardiomyocytes that secrete inflammatory cues. This dissertation focused on identifying factors that influence cardiac remodeling after MI. S100A9 is a neutrophil-derived factor identified that exacerbated infarct wall thinning and cardiac dilation by increasing neutrophil and macrophage infiltration. Similarly, murinoglobulin 1 (Mug1) and galectin (Lgals)3 were macrophage-derived factors identified that regulate …

Introduction: Exercise is well known for its many benefits on the body and most notably the heart. Recent emphasis, and significant resources, have been dedicated to elucidating the molecular mechanisms through which exercise exerts its pluripotent beneficial effects on health and the prevention of disease. A continuous evolution in this field has sought to modulate and optimize exercise in various ways to maximize the benefits. In recent years, a growing appreciation for the impact of circadian rhythms has gained traction and their influence on many essential biological functions have been integrated into exercise physiology (i.e. - chrono-exercise), as well as …

A Neurophysiological Investigation Of Listening Effort In Normal Hearing Adults Using Fnirs And Pupillometry, Jessica Defenderfer
Theses and Dissertations (ETD)
Real-world conversations are often accompanied by some sort of interference that challenges the clarity of the speaker’s message, causing listeners to exert more effort to understand speech. Previous research has demonstrated that when listening to speech becomes difficult, various regions of the brain are recruited beyond those which engage during optimal listening conditions. However, the neural correlates that underly listening effort are not fully understood. Importantly, the pupillary response can be used to index listening effort, such that pupil size increases with increasing cognitive demand. I proposed that pupillometry can be used to characterize the cortical response, such that changes …

In the world of medicine and disease interventions, exercise is too often underlooked as a viable form of treatment or complementary treatment to medication. This is especially true with Parkinson’s Disease, a disease that attacks the basal ganglia of the brain and impairs neuromuscular function. In my analysis, I read a perspective from a PD patient, Gerry Hill, who has struggled with the disease himself and how he used physical activity to aid in his battle with the disease for both physical and psychological aid. Additionally, I performed research to understand how exercise benefits function within the brain. Aerobic exercise, …

The Pathology And Treatment Of Osteoporosis, Shea Munnikhuysen
Senior Honors Theses
Osteoporosis is a disease that causes bone fragility and decreased bone mass. Osteocytes and signaling molecules regulate the function of osteoclasts and osteoblasts. The RANK pathway is a key regulator in osteoclastogenesis. When the osteoclastic function is greater than osteoblastic function, bone integrity decreases. Causes of osteoporosis include hormones, medications, and diet. Treatments for osteoporosis are hormonal, medicinal, and lifestyle changes. More research needs to be done to find more effective medications with fewer negative side effects to improve the overall quality of life for patients. Currently, lab trials are being done on potential new medications to treat osteoporosis.

The mechanistic basis for the formation of aortic aneurysms and dissection needs to be elucidated to facilitate the development of effective medications. β-Aminopropionitrile administration in mice has been used frequently to study the pathologic features and mechanisms of aortic aneurysm and dissection. This mouse model mimics several facets of the pathology of human aortic aneurysms and dissection, although many variables exist in the experimental design and protocols that must be resolved to determine its application to the human disease. In the present brief review, we have introduced the development of this mouse model and provided insights into understanding its pathologic …

Center for Muscle Biology Faculty Publications
Introduction: Despite rigorous rehabilitation aimed at restoring muscle health, anterior cruciate ligament (ACL) injury is often hallmarked by significant long-term quadriceps muscle weakness. Derangements in mitochondrial function are a common feature of various atrophying conditions, yet it is unclear to what extent mitochondria are involved in the detrimental sequela of quadriceps dysfunction after ACL injury. Using a preclinical, non-invasive ACL injury rodent model, our objective was to explore the direct effect of an isolated ACL injury on mitochondrial function, muscle atrophy, and muscle phenotypic transitions.
Methods: A total of 40 male and female, Long Evans rats (16-week-old) were exposed to …

Posttraumatic stress disorder (PTSD) is a debilitating psychiatric disorder which results in deleterious changes to psychological and physical health. Patients with PTSD are especially susceptible to life-threatening co-morbid inflammation-driven pathologies, such as autoimmunity, while also demonstrating increased T-helper 17 (TH17) lymphocyte-driven inflammation. While the exact mechanism of this increased inflammation is unknown, overactivity of the sympathetic nervous system is a hallmark of PTSD. Neurotransmitters of the sympathetic nervous system (i.e., catecholamines) can alter T-lymphocyte function, which we have previously demonstrated to be partially mitochondrial redox-mediated. Furthermore, we have previously elucidated that T-lymphocytes generate their own catecholamines, and strong …
Strong Inferences About Pain In Invertebrates Require Stronger Evidence,

Strong Inferences About Pain In Invertebrates Require Stronger Evidence, Edgar T. Walters
Animal Sentience
Evidence for sentience in animals distantly related to humans is often sought in observations of behavioral and neural responses to noxious stimuli that would be painful in humans. Most proposed criteria for painful sentience in “lower” animals such as decapod crustaceans have no necessary links to the affective (“suffering”) component of pain. The best evidence for painful affect in animals is learned aversion to stimuli associated with noxious experience, and conditioned preference for contexts associated with relief from aversive consequences of noxious experience, as expressed in voluntary behavior. Such evidence is currently lacking for any invertebrate except octopus.
