In 2012, the legalization of recreational cannabis began; as of 2022, 19 states have legalized the recreational use of marijuana (NCSL, 2022). This project aimed to optimize care for patients using cannabis by increasing anesthesia provider knowledge about cannabis. The project's aim was accomplished through a thorough review of the current medical literature and implementation of education to anesthesia providers about the physiological effects and anesthesia implications of cannabis. Thirteen CRNAs took a pre- and post-quiz …


Sex Differences In The Effects Of Cortisol On Muscle Characteristics: A Meta-Analysis, Natalie Bitetti Jan 2024

Sex Differences In The Effects Of Cortisol On Muscle Characteristics: A Meta-Analysis, Natalie Bitetti

CMC Senior Theses

Background: Cortisol plays a central role in both muscle breakdown and growth. These effects are highly dependent on dose and interactions with other hormones. It is known that men and women show considerable differences in their muscle structure and physiology, which are largely driven by hormonal differences. Cortisol release patterns may also vary between the sexes, with current research showing considerable disagreement. The interplay between cortisol and muscle, two highly variable and sexually dimorphic factors, may prove to have different effects in males versus females.

Objective: This meta-analysis integrates existing research on sex differences in cortisol-muscle physiology with existing research …


Impacts Of Environmental Stressors On Native South Dakota Amphibian Physiology And Survival, Danielle Jean Galvin Dec 2023

Impacts Of Environmental Stressors On Native South Dakota Amphibian Physiology And Survival, Danielle Jean Galvin

Dissertations and Theses

Amphibian populations around the world are declining, with some of the most likely drivers behind these declines including emerging infectious diseases and environmental contaminants. To address major gaps in the current literature, I sought to evaluate the effect of two major environmental stressors on various aspects of amphibian physiology: emerging infectious diseases and environmental contaminants. Emerging infectious diseases of amphibians include fungal, viral, and parasitic pathogens which have expanded in host range, either geographically or in competent host species. Environmental contaminants include chemicals which may be naturally occurring in the environment, or which may be introduced to the environment, often …


Identification And Assessment Of Fixed Versus Growth Mindsets In Human And Anatomy Physiology Undergraduate Students, Jayanti Shukla May 2023

Identification And Assessment Of Fixed Versus Growth Mindsets In Human And Anatomy Physiology Undergraduate Students, Jayanti Shukla

Honors Theses

Fixed mindsets and growth mindsets are present in individual’s attitudes, affecting their motivations to complete responsibilities or overcome challenges. In this study, we aim to identify and assess the mindsets of undergraduate students partaking in the Human Anatomy and Physiology (HAP) undergraduate course at the University of Mississippi, the gateway course being well-known for its difficulty and being described as “daunting” to many allied-health majors. By utilizing Carol Dweck’s growth mindset model, we are interested in determining whether students possess a “fixed” mindset versus a “growth” mindset, in conjunction to assessing their classroom performance correlating with that demonstrated mindset. An …


Eco-Interoception: What Plants, Fungi And Protista Have Taught My Body, Sara Riley Dotterer May 2023

Eco-Interoception: What Plants, Fungi And Protista Have Taught My Body, Sara Riley Dotterer

Art Theses and Dissertations

To me, ecology is the relational, full-body awareness that I am made up of and deeply connected to everything around me; and for better or worse, this is reciprocal. I form ecotones, an ecological transitional zone between two ecosystems, with the world around me. I use this ecotonal lens to blur binaries and dissolve boundaries between me and the world “outside my body.” During my Masters of Fine Arts at Southern Methodist University, I have continuously explored and represented the lives of various more-than-human species outside of my body, including plants, fungi and protista through an ecotonal lens. Although these …

Impacts Of Dietary Restriction On A Drosophila Model Of Werner Syndrome, Eileen Sember May 2023

Impacts Of Dietary Restriction On A Drosophila Model Of Werner Syndrome, Eileen Sember

College of Arts & Sciences Senior Honors Theses

Werner syndrome (WS) is an autosomal recessive disorder that results in premature aging and occurs in 1 in 1,000,0000 to 1 in 10,000,000 people. In humans, WS is the result of mutations that render the WRN gene, that contains a helicase and an exonuclease domain, non-functional. Currently, there is no cure for WS in humans, making dietary and lifestyle interventions attractive for increasing the quality and longevity of lives. Diet restriction (DR) has been shown to extend the lifespan of several model organisms, including Drosophila melanogaster, making it a strong candidate for WS treatment. In this thesis, mutant flies …

Chronic Circadian Disruption Increases Risk For Cardiovascular Disease, Jazmine I Benjamin Jan 2023

Chronic Circadian Disruption Increases Risk For Cardiovascular Disease, Jazmine I Benjamin

All ETDs from UAB

Circadian disruption is a disturbance in biological timing which can occur within or between different organizational levels, ranging from molecular rhythms within specific cells to misalignment of behavioral and environmental cycles. Previous work has shown that changing the timing of food availability is sufficient to lower blood pressure and improve insulin sensitivity in prediabetic males, demonstrating the importance of timing of food intake for cardiovascular health. Findings from our group demonstrated that less than one week of mistimed feeding is sufficient to invert diurnal blood pressure rhythms, although kidney excretory rhythms and kidney function remained aligned with the light-dark cycle. …


An Examination Of Kinanthropometric And Physical Injury Risk Factors In Elite Australian Football, Callum J. Mccaskie Jan 2023

An Examination Of Kinanthropometric And Physical Injury Risk Factors In Elite Australian Football, Callum J. Mccaskie

Theses: Doctorates and Masters

Kinanthropometric assessment is an integral part of understanding an athlete’s physical profile and readiness for competition. This typically includes a variety of different assessments which serve to quantify body shape, proportion, and composition in a bid to understand human physiology. Common assessments include stature, body mass, limb ratios, body circumferences, body mass index, skinfold testing, body composition testing, and musculoskeletal morphological evaluations. Specifically, kinanthropometric evaluations have involved the characterisation of athletes according to sport, sex, competition level and playing position. While this has provided researchers and practitioners with greater insight into athletic phenotypes, more purposeful kinanthropometric assessments which focus on …

Ulcerative Colitis, Randy Kinietz Jan 2021

Ulcerative Colitis, Randy Kinietz

Nursing Student Class Projects (Formerly MSN)

This poster briefly covers the most important concepts of ulcerative colitis (UC). UC is a complex disease process and the exact etiology is not yet known. Many researchers are currently looking to find the cause of the disease and treatment options that can target the exact pathophysiological process. Nurses are instrumental in the care of UC, especially in an outpatient setting. Education on medications and proper follow-up appointments are the key to maintaining remission, reducing flare-ups, and cancer screening. Although UC is a complex disease, a multidisciplinary approach will reduce complications and prolong remission.


Physiological Stability During Oral Feeding In Preterm Infants: Associations With Feeding Behaviors And Cues, Cindy M. Lund Jan 2021

Physiological Stability During Oral Feeding In Preterm Infants: Associations With Feeding Behaviors And Cues, Cindy M. Lund

Graduate Research Theses & Dissertations

The purpose of this study was to examine the relationship between measures of physiological stability/instability during feeding. An additional aim was to determine if behaviors associated with physiological stability were also perceived as readiness or stress cues. Participants included 5 preterm infants (<37 weeks gestation) with no craniofacial anomalies. Infants were videotaped when they were taking at least 90% of prescribed volume. This study analyzed the common behaviors seen in preterm infants during bottle feeding to determine if there were associations with measures of physiological stability. Behaviors were also analyzed to determine which were perceived as indicating stress or readiness to feed by novice observers. Coding was conducted offline using Noldus Observer software.

Results revealed a statistically significant relationship between behaviors classified as stress cues and HR instability. There was not a significant association between stress cues and RR or SPO2. Binomial testing identified specific preterm infant feeding behaviors that were more often classified as stress cues, with significance noted in audible swallow and vocalization. Several of the specific preterm …


Impact Of 17-Beta Estradiol And Moderate-Intensity Exercise On Mesenteric Arterial Function Of Uc Davis Type-2 Diabetes Mellitus Rats, Md Rahatullah Razan Jan 2021

Impact Of 17-Beta Estradiol And Moderate-Intensity Exercise On Mesenteric Arterial Function Of Uc Davis Type-2 Diabetes Mellitus Rats, Md Rahatullah Razan

University of the Pacific Theses and Dissertations

The studies in this dissertation were designed to investigate the impacts of estrogen (17-β estradiol/E2) and moderate-intensity exercise (MIE) on the mesenteric arterial (MA) function of the University of California Davis type-2 diabetes mellitus (UCD-T2DM) Rat model. Our recent report suggests that diabetes impairs MA vasorelaxation in both sexes of the UCD-T2DM model. Particularly, we reported that MA from prediabetic male rats showed a greater impairment compared to that in prediabetic females. However, when females become diabetic, they exhibit a greater vascular dysfunction than males. Therefore, the aim of the first study was to investigate whether female sex hormone, specifically …

Viability Of Physiologically Timed Relaxation Interventions In Children With Asd, Nicholas Mendez Jan 2021

Viability Of Physiologically Timed Relaxation Interventions In Children With Asd, Nicholas Mendez

CMC Senior Theses

Autism Spectrum Disorder (ASD) is an increasingly common developmental disorder that changes how people experience the world and affects individuals’ social interactions and often leads to many adverse behaviors. Current literature dictates that a primary contributor to these adverse behaviors is that those with ASD have difficulty determining their own emotional states and determining the physiological signals that their body sends them. A study by Dr. Sarabadani et al. determined that it was possible to monitor the physiology of an individual with ASD and correlate certain signals to emotions, such as stress. These findings indicate the feasibility of establishing a …


Plasma Resuscitation Attenuates Intestinal Barrier Disturbance Following Hemorrhagic Shock., Jessica E. Schucht Dec 2020

Plasma Resuscitation Attenuates Intestinal Barrier Disturbance Following Hemorrhagic Shock., Jessica E. Schucht

Electronic Theses and Dissertations

Background: Intestinal ischemia-reperfusion injury (IIRI) following resuscitated hemorrhagic shock (HS/RES) leads to endothelial damage, microcirculatory dysfunction and intestinal barrier breakdown, increasing intestinal permeability. This pathologic process contributes pathophysiology of multiple organ dysfunction syndrome (MODS) in some trauma patients. Although vascular smooth muscle machinery remains intact, microvascular vasoconstriction occurs secondary to endothelial cell damage, resulting in further ischemia and organ injury. Used separately, resuscitation with Fresh Frozen Plasma (FFP) or Direct Peritoneal Resuscitation (DPR) improves the intestinal microcirculation and alleviates organ injury. Further examination of these effects individually or combined could aid in the resuscitation of hemorrhagic shock. Methods: Sprague Dawley …

Influence Of Heating And Biological Sex On Vascular Dysfunction Associated With Long-Duration Sitting And Standing, Aaron Richard Caldwell Aug 2019

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) …


Integration Of Cone Photoreceptor Signals In Macaque Lgn Neurons, Paul B. Brown Jan 2019

Integration Of Cone Photoreceptor Signals In Macaque Lgn Neurons, Paul B. Brown

All ETDs from UAB

Despite advances in the understanding of the primate visual system, much is yet to be learned about the way light signals sum to create our perception of the world. This is especially true at the simplest level of visual processing—the summation of two individual cone photoreceptor signals. How such signals combine to create visual perception has not been assessed in vivo. We used an adaptive optics scanning laser ophthalmoscope (AOSLO) to deliver binarized noise movies to identified groups of cones within the receptive fields of neurons in the macaque lateral geniculate nucleus (LGN). Recordings of neural action potentials within the …


The Manifestations Of Fatigue In Amateur Boxing Performance, Emily C. Dunn Jan 2019

The Manifestations Of Fatigue In Amateur Boxing Performance, Emily C. Dunn

Theses: Doctorates and Masters

A subjective method of judgment, the “Ten Point Must-System” (TPMS), was introduced into amateur boxing in 2013. To be successful, boxers must deliver forceful punches and exert dominance over an opponent. There has been limited research examining the strategies used by boxers to win fights under the TPMS and whether these strategies induce fatigue that is sufficient to significantly affect punch force. The overall objective of the five studies contained in this thesis was to describe, in relation to fatigue, the performance characteristics of male amateur boxers under the TPMS, and improve our understanding of the physical characteristics associated with …


Improving Techniques To Study Equine Cervical Mucociliary Clearance, Melissa A. Hawkes May 2018

Improving Techniques To Study Equine Cervical Mucociliary Clearance, Melissa A. Hawkes

Electronic Theses and Dissertations

Bacterial uterine infections inflict major losses on the equine breeding industry. These infections usually arise from bacteria introduced at breeding. Micro-currents propelled by ciliated cells between the folds of the uterus and cervix have been proposed as a means by which contaminants are expelled. Previous data have shown possible ciliary micro-currents propelling carbon particles, occasionally rotating, through cervical folds. However, adherence to the epithelium may have interfered with movement of carbon in these studies. Therefore, we tested potentially non-adherent substances to reveal ciliary micro-currents on the equine cervix under high magnification video-endoscopy. We hypothesized that polyethylene green microspheres 1 - …


Allergen Specific Immunotherapy And The Effect On Allergy Induced Asthma, Cord Tanner Landrum Jan 2018

Allergen Specific Immunotherapy And The Effect On Allergy Induced Asthma, Cord Tanner Landrum

Physician Assistant Scholarly Project Papers

Allergies are a major public health problem affecting over 300 million people worldwide (Asamoah et. al). An allergic response can occur when a harmless substance, such as tree pollen, is inhaled into the body and mistakenly identified as a harmful substance. Antibodies then bind to the allergen causing a release of chemicals that leads to symptoms such as nasal congestion, runny nose, itchy eyes or skin reactions. For some people, this reaction can also affect the lungs and airways leading to asthma symptoms.

This review analyzes articles from PubMed, Cochran, Clinical Key and references found from UpToDate articles to assess …

Gait Changes During Exhaustive Running, Nathaniel I. Smith Mar 2016

Gait Changes During Exhaustive Running, Nathaniel I. Smith

Masters Theses

Runners adopt altered gait patterns as they fatigue which may increase energy expenditure and susceptibility to certain overuse injuries. Previous investigations have described changes in muscle performance and kinematic gait variables resulting from running fatigue. The purpose of this investigation was to characterize changes in joint moment patterns that develop as runners fatigue in order to better understand the kinetic bases for kinematic fatigue effects. It was hypothesized that when fatigued, runners would demonstrate increases in stance time, peak stance phase knee flexion angle, peak knee extension moment, peak swing phase hip flexion moment, and hip extension and plantarflexion angular …


The Effects Of The Menstrual Cycle On Agility, Kheniser G. Karim Jan 2016

The Effects Of The Menstrual Cycle On Agility, Kheniser G. Karim

ETD Archive

It has long been speculated that the menstrual cycle affects athletic performance. Whether athletic performance is impacted by menstrual cycle phase is dependent upon an array of factors: the type of activity (i.e., aerobic or anaerobic); oral contraceptive (OC) use; and, possibly, if mental processing is required during the execution of the task. Prior research has indicated that alterations in estradiol (E2) affects cognitive performance. However, there is a paucity of information about whether E2 modulates the speed of cognitive processing in a sports setting, which may cause alterations in sport performance throughout the menstrual cycle. Additionally, variations in E2 …
