Effect Of Metabolic Rate On Mitochondrial Efficiency During Exercise In Human Skeletal Muscle In Vivo, Muhammet Enes Erol
Effect Of Metabolic Rate On Mitochondrial Efficiency During Exercise In Human Skeletal Muscle In Vivo, Muhammet Enes Erol
Masters Theses
Introduction: Recent evidence in isolated mitochondria and permeabilized muscle fibers in ex vivo using simultaneous measurements of O2 consumption and ATP production suggest that mitochondrial efficiency provides an additional mechanism to fine-tune oxidative phosphorylation rate to ATP demand in skeletal muscle. However, in the absence of a direct measurement of both VO2 and ATP synthesis from the same region of the contracting muscle, whether this mechanism plays a role in the skeletal muscle in vivo is still unknown. Purpose: Using a noninvasive approach combining phosphorus and proton magnetic resonance spectroscopy (31P/1H-MRS), the present study …
Unearthing Complexity: Tangible Histories Of Water And Earth, Alexis Violet
Unearthing Complexity: Tangible Histories Of Water And Earth, Alexis Violet
Masters Theses
Unearthing Complexity investigates conceptions of time and surface through geological stories of the water and earth. Building on theories of deep time, hydrofeminism, critical zones, and grounding, I hope to foster a deeper awareness of time scales other than our own and a more tangible understanding of the embodied experience of matter in the universe. Working toward a new literacy of the water and earth in which they are recognized as living, changing bodies to which we are inherently tied at a molecular level, the site of this multiscalar inquiry occurs in the coastal zones of the Narragansett Bay where …
Stretch Activation During Fatigue Improves Relative Force Production In Fast-Contracting Mouse Skeletal Muscle Fibers, Philip C. Woods
Stretch Activation During Fatigue Improves Relative Force Production In Fast-Contracting Mouse Skeletal Muscle Fibers, Philip C. Woods
Masters Theses
Stretch activation (FSA) is the delayed increase in fiber specific tension (force per cross-sectional area) following a rapid stretch and can improve muscle performance during repetitive cyclical contractions. Historically considered minimal in skeletal muscle, our recent work showed the ratio ofstretch- to calcium-activated specific tension (FSA/F0) increased from 10 to 40% with greater inorganic phosphate (Pi) levels in soleus muscle fibers (Straight et al., 2019). Given Pi increases with muscle fatigue, we hypothesize that FSA helps maintain force generation during fatigue. To test this, FSA, induced by a stretch of 0.5% …
Deciphering The Role Of Mitochondrial Physiology And Thermal Acclimation In Shaping Whole Organismal Performance Of An Invasive Forest Pest, Essa Alrashdi
Masters Theses
Environmental factors such as temperature are substantial determinants of the spongy moth, L. dispar, distribution, reproduction, and growth. Accumulating energy reserves at the larval stage is particularly important to L. dispar, since the larvae metamorphose into a fully-grown, non-feeding adult. As non-feeding adults, the energy balance of the pupae must be adequate, to ensure enough energy reserves for adult dispersal, egg maturation and overall persistence of the species in the region. At this stage, environmental temperature also determines daily metabolic demands, and the overall cost of sustaining ecologically relevant activities. Various hypotheses describing a mismatched growth and metabolic …
The Effect Of Bovine Endometrial Cell Conditioned Media On In Vitro Produced Bovine Embryo Development And Gene Expression, Mary A. Oliver
The Effect Of Bovine Endometrial Cell Conditioned Media On In Vitro Produced Bovine Embryo Development And Gene Expression, Mary A. Oliver
Masters Theses
In vitro produced (IVP) bovine embryos provide enhanced genetic value and a means for studying early embryonic development. However, IVP embryos are developmentally compromised and are lower quality compared to in vivo derived (IVD) embryos. Consequently, after transfer pregnancy rates from IVP embryos are consistently lower, as they exhibit the highest amounts of pregnancy failure during the early embryonic phase (prior to day 28). Progesterone (P4) has been shown to influence bovine endometrial epithelial (EPI) and stromal fibroblast (SF) cells to secrete developmentally important molecules that promote early embryo development and conceptus elongation. However, IVP embryos are not exposed to …
Does Epa Cause A Decrease In Inflammation Of Bend.3 Cells Through Ffar4?, Clay J. Weidenhamer
Does Epa Cause A Decrease In Inflammation Of Bend.3 Cells Through Ffar4?, Clay J. Weidenhamer
Masters Theses
Atherosclerosis is an inflammatory disease initiated by low and oscillatory shear stress on the endothelium. The inflammatory process recruits leukocytes to the vessel wall by expression of the adhesion molecule VCAM-1. Activation of the NF-κB inflammatory signaling pathway is responsible for the increase in VCM-1 expression. Omega 3 FAs, such as EPA, reduce the risk of atherosclerosis by decreasing this inflammatory response. The pathway by which omega 3 FAs is proposed to inhibit inflammation includes activating FFAR4 to decrease NF-κB activation thereby reducing expression of adhesion molecules. We hypothesized that treatment of endothelial cells with 30 μM EPA would decrease …
Link Between Muscle And Whole-Body Energetic Responses To Exercise, Christopher M.T. Hayden
Link Between Muscle And Whole-Body Energetic Responses To Exercise, Christopher M.T. Hayden
Masters Theses
Substantial evidence exists regarding how skeletal muscles use energy and how this affects muscular performance. What remains unclear is how characteristics of muscle energetics affect whole-body energetics during daily living, and what effects this may have on mobility. The goal of this study was to determine the associations between muscle and whole-body energetics including the relationships between: 1) muscle PCr depletion (∆PCr) in response to light intensity isotonic contractions and the oxygen deficit at the onset of a 30-min treadmill walk (30MTW), and, 2) muscle oxidative capacity and excess post-exercise oxygen consumption (EPOC; 30MTW), respiratory exchange ratio (RER; 30MTW), and …
Patterns And Mechanisms Of Intraspecific Trait Variation Across Thermal Gradients In A Marine Gastropod, Andrew R. Villeneuve
Patterns And Mechanisms Of Intraspecific Trait Variation Across Thermal Gradients In A Marine Gastropod, Andrew R. Villeneuve
Masters Theses
As the earth’s climate changes due to anthropogenic emissions, it has increasingly become an imperative within the ecological community to understand existing species adaptations to climate change. Much focus has been paid to how a species might react to climate change, but the role of locally adapted traits and responsible environmental mechanisms have received less attention. Quantifying how sublethal (e.g. growth rates) and lethal (e.g. thermal tolerance) trait performance vary between populations can thus improve our understanding of how populations, and the entire species, will react to climate change. Here, I quantified the spatial patterns of performance of several traits …
Effects Of Normobaric Hypoxia On Oculomotor Dynamics Of Aviator Students During A Simulated Flight Task, Carl Wesley Rider, Abby Mccarty, Anna Blackley, Austin Deshner, Josh Engberg, Kaela Ehrlich, Theodore Hu, Maja Jankovic, Moroni De Moors, Jared Hornsby, Mitchell Morrison, Brian Walsh
Effects Of Normobaric Hypoxia On Oculomotor Dynamics Of Aviator Students During A Simulated Flight Task, Carl Wesley Rider, Abby Mccarty, Anna Blackley, Austin Deshner, Josh Engberg, Kaela Ehrlich, Theodore Hu, Maja Jankovic, Moroni De Moors, Jared Hornsby, Mitchell Morrison, Brian Walsh
Masters Theses
Hypoxia occurs when the body's tissues are unable to obtain adequate oxygen supply and is the primary environmental factor present when pilots are exposed to increasing altitude levels. Hypoxia leads to impaired vision, cognition, and motor control function, which can negatively affect performance and become deadly if a pilot becomes incapacitated. Thus, objective identification of early-onset hypoxia is critical to increase the time of useful consciousness and prevent physiological episodes. Of the few studies utilizing eye-tracking, there is disagreement and mixed results concerning saccadic eye metrics as a means to measure and detect hypoxia. Therefore, the purpose of this study …
Seasonal Temperature Changes In Three Midwestern Wastewater Streams And The Effects On Fish Assemblages And Physiology, Ryan William Sparks
Seasonal Temperature Changes In Three Midwestern Wastewater Streams And The Effects On Fish Assemblages And Physiology, Ryan William Sparks
Masters Theses
Midwestern United States undergo extreme temperature and precipitation fluctuations throughout the year, which leads to changing habitats within Illinois river systems. Wastewater treatment facilities have long been used to treat sewage and reduce the organic products in sewage before releasing it into aquatic environments. Wastewater treatment facilities must maintain optimal conditions, especially temperature, for reproduction and growth of facilitated bacteria that break down organic materials in wastewater. The objectives for this study were to determine the thermal effects of wastewater treatment facilities on receiving waters; and secondly, to investigate the influence of these wastewater facilities on fish abundance and assemblages. …
Seasonal Variation In Mitochondrial Bioenergetics Of The Bluegill Sunfish, Lepomis Macrochirus, From A Shallow Midwest River, Derick Isaac Lamptey
Seasonal Variation In Mitochondrial Bioenergetics Of The Bluegill Sunfish, Lepomis Macrochirus, From A Shallow Midwest River, Derick Isaac Lamptey
Masters Theses
As average global temperature increase, the frequency and magnitude of extreme temperatures in shallow aquatic ecosystems are more ubiquitous. In order to understand how these changing thermal regimes affect aquatic ectotherms, it is essential to develop studies evaluating the response of ectotherms to seasonal fluctuating thermal regimes. Previous studies on fluctuating temperature regimes have reported an increased physiological stress leading to morphological, behavioral and biochemical adaptations. From the latter, the adaptive capacity and seasonal performance associated with optimal function of the oxidative phosphorylation system (OXPHOS) are key for species persistence. However, studies on this matter are scarce. This study explores …
Link Between Energy Investment In Biosynthesis And Cellular Resistance To Oxidative Insult: Test The Cost-Quality Hypothesis In Insects, Taiwo Bolanle Iromini
Link Between Energy Investment In Biosynthesis And Cellular Resistance To Oxidative Insult: Test The Cost-Quality Hypothesis In Insects, Taiwo Bolanle Iromini
Masters Theses
“The metabolic cost of growth is the amount of energy invested to fuel the anabolic biochemical reactions of biosynthesis. It has been implicated in the efficiency of farm animals and fishes, thus, increased economic profit. The metabolic cost of growth in the cockroach nymph was reported to be 20-fold higher than that of the painted lady butterfly caterpillar. The cost-quality hypothesis was proposed to explain the extremely low biosynthesis energy cost in painted lady caterpillar when physiological and ecological processes the metabolic growth cost was attributed to could not. In this study, the cost-quality hypothesis was tested.
Midgut cells were …
The Effects Of Acidosis On Calcium Dependent Binding Of A Single Crossbridge, Matthew Unger
The Effects Of Acidosis On Calcium Dependent Binding Of A Single Crossbridge, Matthew Unger
Masters Theses
Intracellular acidosis is a putative agent of skeletal muscle fatigue, in part, because acidosis depresses the calcium (Ca2+) sensitivity and force production of muscle (18, 50). However, the molecular mechanisms behind this depression in Ca2+ sensitivity and force production are unknown. This gap in knowledge poses a significant challenge in generating a complete understanding of the fatigue process. To close this gap, the ability of myosin to bind to a single actin filament was measured under acidic conditions, in a laser trap assay, with and without regulatory proteins. Decreasing pH from 7.4 to 6.5 reduced the frequency …
Mechanisms And Mitigation Of Skeletal Muscle Fatigue In Single Fibers From Older Adults, Aurora Foster
Mechanisms And Mitigation Of Skeletal Muscle Fatigue In Single Fibers From Older Adults, Aurora Foster
Masters Theses
Skeletal muscle fatigue is the contraction-induced decline in whole muscle force or power, and can be greater in older versus young adults. Fatigue primarily results from increased metabolism elevating phosphate (Pi) and hydrogen (H+), which alters myosin-actin interactions; however, which steps of the myosin-actin cross-bridge cycle are changed and their reversibility are unclear. PURPOSE: This study sought to: 1) Examine the effects of elevated Pi and H+ on molecular and cellular function, and 2) Test the ability of deoxyadenosine triphosphate (dATP), an alternative energy to adenosine triphosphate (ATP), to reverse the contractile changes induced …
Dental Topographic Analysis Of Maxillary And Mandibular Phyllostomid Bat Dentitions: Implications For Dietary Prediction In The Fossil Record, Colin Pellegrom
Dental Topographic Analysis Of Maxillary And Mandibular Phyllostomid Bat Dentitions: Implications For Dietary Prediction In The Fossil Record, Colin Pellegrom
Masters Theses
Mammalian dental anatomy has evolved in accordance with the physical properties of its diet, and multiple features on each tooth have specific functions related to the breakdown of food during mastication and ingestion. Tooth structure is under tight genetic control and much of the anatomical variation in dentition across species is related to adaptation to a specific dietary regime. This diet-dentition relationship can be exploited to reconstruct mammalian diets from fossil specimens through calculation of dental topographic metrics. To date, most studies of dietary reconstruction using dental topography have focused on mandibular molars; thus, this study seeks to test whether …
Developmental Exposure To Xenoestrogens: Effects On The Mouse Mammary Gland Development And Response To Estrogen, Durga Kolla
Developmental Exposure To Xenoestrogens: Effects On The Mouse Mammary Gland Development And Response To Estrogen, Durga Kolla
Masters Theses
Humans experience ubiquitous exposures to estrogenic environmental chemicals from food, personal care products, and other industrial and consumer goods. Bisphenol A (BPA), a well-studied xenoestrogen, is known to alter development of estrogen-sensitive organs including the brain, reproductive tract, and mammary gland. Bisphenol S (BPS), which has a similar chemical structure to BPA, is also used in many consumer products, but its effects on estrogen-sensitive organs in mammals has not been thoroughly examined. In our study, pregnant CD-1 mice were orally exposed to BPS or ethinyl estradiol (EE2, a positive control for estrogenicity) from gestational day 9 through postnatal day (PND) …
Effects Of Instability On Core Muscle Activation In A Side Bridge, Erin E. Kishman
Effects Of Instability On Core Muscle Activation In A Side Bridge, Erin E. Kishman
Masters Theses
Training the musculature of the core continues to be perceived as an essential component of conditioning and rehabilitation settings (11). A popular way to train the core is with the use of instability devices, such as Swiss ball or suspension trainer. However, there is limited research on the effects of these devices on core muscle activity. The purpose of this study was to examine core muscle activity during side bridge variations with and without instability devices (Floor, Swiss Ball, and TRX) through electromyography (EMG) of the rectus abdominis, external oblique, erector spinae, and latissimus dorsi. 39 participants performed three variations …
The Effects Of Two Different Sports Drinks On Rpe And Finishing Speed Of An Endurance Run In Highly Trained Distance Runners, Matthew J. Feldhake
The Effects Of Two Different Sports Drinks On Rpe And Finishing Speed Of An Endurance Run In Highly Trained Distance Runners, Matthew J. Feldhake
Masters Theses
The purpose of this study was to compare the effects of a protein-containing sport drink with a traditional non-protein sport drink has on ratings of perceived exertion (RPE) and finishing speed of an half marathon. Of the possible factors that would support including protein in a sport drink the primary one was its inhibitory effect on serotonin release in the brain. This could help attenuate perceived exertion, thus allowing individuals to compete at a higher level for longer durations (Davis, Alderson, & Welsh, 2000).
This study was conducted using nine members of the Eastern Illinois University Men's Cross Country team. …

Impact Of Temperature Increase On Freshwater Fish Species: Energetics And Muscle Mechanics Of Two Centrarchids, Israt Jahan
Masters Theses
Fishes have evolved physiologically to live within a specific range of environmental variation and existence outside of that range can be stressful or fatal. These ranges can coincide for fishes that evolved in similar habitats. This study investigates physiological processes limiting thermal tolerance, specifically how changes in water temperature affect the swimming energetics and muscle mechanics in largemouth bass (Micropterus salmoides) and bluegill (Lepomis macrochirus). I focused on the impact of temperature change at the muscle level in these two species and the capacity to adapt to rapid changes in the environment. Fish were housed at …
Botswana’S Elephant-Back Safari Industry – Stress-Response In Working African Elephants And Analysis Of Their Post-Release Movements, Tanya Lama
Masters Theses
Understanding how African elephants (Loxodonta africana) respond to human interactions in ecotourism operations is critical to safeguarding animal and human welfare and sustaining wildlife ecotourism activities. We investigated the stress response of elephants to a variety of tourist activities over a 15-month period at Abu Camp in northern Botswana. We compared fecal glucocorticoid metabolite (FGM) concentrations across three elephant groups, including: eight elephants in an elephant-tourism operation (Abu herd), three elephants previously reintroduced back into the wild from the Abu herd, and wild elephants. There were no differences in FGM concentrations between the three groups of elephants. The highest observed …
The Role Of Creg1 As A Master Regulator Of Liver Function, Abdulrahman Siran Aldaghmi
The Role Of Creg1 As A Master Regulator Of Liver Function, Abdulrahman Siran Aldaghmi
Masters Theses
The liver is known as the chemical factory of the body because it performs a wide range of biochemical functions required for life. Since the liver has such an important role in regulation of normal physiological processes, liver diseases cause a high rate of morbidity and mortality. Therefore, understanding the mechanisms of liver development will shed light on the causes of liver disease. In this study, a cell line model that utilizes rat hepatoma cells (Fg14) and hepatoma variant cells (H11) was used to identify master regulators of liver gene expression. Whole genome expression studies identified the gene CREG1 (Cellular …

Masters Theses
Fish natural habitats are increasingly contaminated with various estrogenic compounds, including 17β estradiol (E2). This compound causes adverse effects on the reproductive system of male fish; however, the effects of E2 on other aspects of fish metabolism, morphology and histopathological changes in internal organs are not well known. The objective of this study is to evaluate the effects of E2 exposure on the basal and stressed metabolic rate, morphological changes in body shapes, and histological changes in the liver tissues of sunfish species. Fish were held individually in ten gallon tanks under two treatments of 40 and 80 ng/L and …
Metabolic And Morphologic Shifts In Neuro2a Cells Cultured In Galactose Medium, Leah Welker
Metabolic And Morphologic Shifts In Neuro2a Cells Cultured In Galactose Medium, Leah Welker
Masters Theses
It has been observed that highly-proliferating cells, such as cancer cells, rely mainly on glycolysis for ATP production, regardless of presence of oxygen. This effect, however, can be reversed by changing the main energy substrate in the medium from glucose to galactose. The oxidation of galactose in glycolysis yields less net ATP, presumably forcing the cell into OXPHOS. This has been established in many cell lines, including HeLA, HepG2, and skeletal muscle cells. As of yet, this has not been reproduced in neuronal cells. Using Neuro2a, a murine neuroblastoma cell line, this study exposes neuronal cells to galactose medium, and …
The Effects Of Limb Dominance On Cross-Education In A Four Week Resistance Training Program, Caitlin Wend
The Effects Of Limb Dominance On Cross-Education In A Four Week Resistance Training Program, Caitlin Wend
Masters Theses
Cross-education is known as the phenomenon of strength transfer from the trained side of the body to the untrained side of the body by unilateral resistance training. Research has shown that limb dominance has an effect on the amount of strength that is gained on the untrained side. Studies have found that there is a greater cross over effect in strength from the dominant side of the body to the non-dominant side of the body than vice versa. The present study examined this effect by taking 12 college females and splitting them into three groups: dominant training, non-dominant training, and …
The Influence Of Different Pre-Exercise Routines On Sprint Performance, Rok Mravljak
The Influence Of Different Pre-Exercise Routines On Sprint Performance, Rok Mravljak
Masters Theses
Sprint performance can be enhanced by interventions for short-term (acute) purposes and/or long-term purposes. Acute neuromuscular responses are usually achieved by using different pre-exercise routines at the end of the warm-up period. Recently, there have been several studies examining the effects of various pre-exercise routines on sprint performance, yet there has not been a research study designed that compared the three most commonly used pre-exercise routines in professional and recreational sports (static stretching, dynamic stretching and foam-rolling). Therefore, this study investigated and compared the results of static stretching, dynamic stretching, self-myofascial release and the control group, in order to provide …
Follicular Dynamics In Insulin Resistant Mares, Julio Cesar Prado
Follicular Dynamics In Insulin Resistant Mares, Julio Cesar Prado
Masters Theses
Obesity and insulin resistance have been linked to prolonged interovulatory period, aberrations in the estrous cycle, and continuous reproductive activity during the non-breeding season. EMS has been determined to influence the intrafollicular environment of mare ovaries. In humans, insulin resistance has been linked to polycystic ovaries as part of Polycystic Ovarian Syndrome (PCOS). A study was conducted to determine 1) the impact of insulin resistance on follicle growth and size at ovulation, and 2) whether predicted ovulatory follicles respond to hCG administration in Insulin-resistant (IR) mares. Mares were selected for the study based on insulin sensitivity and separated into an …
Modifications Of Myofilament Structure And Function During Global Myocardial Ischemia, Mike K. Woodward
Modifications Of Myofilament Structure And Function During Global Myocardial Ischemia, Mike K. Woodward
Masters Theses
Cardiac arrest is a prevalent condition with a poor prognosis, attributable in part to persistent myocardial dysfunction following resuscitation. The molecular basis of this dysfunction remains unclear. We induced cardiac arrest in a porcine model of acute sudden death and assessed the impact of ischemia and reperfusion on the molecular function of isolated cardiac contractile proteins. Cardiac arrest was electrically induced, left untreated for 12 min, and followed by a resuscitation protocol. With successful resuscitations, the heart was reperfused for 2 h (IR2) and the muscle harvested. In failed resuscitations, tissue samples were taken following the failed efforts (IDNR). Actin …

The Effects Of Ovarian Hormones And Exercise On Gene Markers Of Cardiac Dysfunction, Anisha S. Patel
The Effects Of Ovarian Hormones And Exercise On Gene Markers Of Cardiac Dysfunction, Anisha S. Patel
Masters Theses
Heart disease is the leading cause of death in women in the United States. Premenopausal women appear to have better cardiac function and lower risk of heart disease compared to male postmenopausal female counterparts. Ovarian hormone loss influences blood pressure homeostasis and causes systemic inflammation, which may result in chronic stress on the heart. Two key physiological changes in cardiac dysfunction are reemergence of the fetal gene pattern and myocardial remodeling. Physical activity has been linked to improved cardiac function. The purpose of this study was to investigate the effects of ovariectomy on early markers of cardiac dysfunction and fibrosis …
D-Galactose Decreases Mitoneet Levels In Liver Cancer Cells: Impact On Cellular Bioenergetics, Sudip Paudel
D-Galactose Decreases Mitoneet Levels In Liver Cancer Cells: Impact On Cellular Bioenergetics, Sudip Paudel
Masters Theses
Galactose is a simple sugar that at supraphysiological concentrations accelerates aging and age-related complications, which lead to impaired mitochondrial functions. MitoNEET is a small mitochondrial membrane protein with a molecular mass of 12.2 kDa that functions in diabetes, iron metabolism, regulation of oxidative phosphorylation (OXPHOS) and reactive oxygen species (ROS) homeostasis. MitoNEET knockdown increases cellular respiration rates and ROS levels similar to galactose treatment. Pioglitazone, an antidiabetic drug, binds to mitoNEET and ameliorates galactose toxicity. Cellular mitoNEET levels, exposure of cells to galactose medium, and pioglitazone treatment directly influence cellular respiration. To elucidate the role of mitoNEET in galactose induced …
