The Role Of Adaptive Immunity In Chronic Hypoxia-Induced Pulmonary Hypertension, Levi David Maston
The Role Of Adaptive Immunity In Chronic Hypoxia-Induced Pulmonary Hypertension, Levi David Maston
Biomedical Sciences ETDs
Inflammation is a prominent pathologic feature in pulmonary arterial hypertension as demonstrated by pulmonary vascular infiltration of inflammatory cells, including T and B lymphocytes. However, the contribution of the adaptive immune system is not well characterized in pulmonary hypertension (PH) caused by chronic hypoxia (CH). Inflammatory cells, through various mechanisms, have the capability to increase pulmonary vascular resistance in various disease states. CD4+T cells have the potential to play a significant role in the disease process initiated by hypoxia. CD4+T cells are largely responsible for orchestrating downstream immune processes and are critical in focusing and amplifying …

International Journal of Exercise Science
International Journal of Exercise Science 12(5): 1254-1264, 2019. Evidence suggests that high intensity exercise aided by musicrenders positive results in health related fitness components. However, less is known about the influence synchronous and asynchronous music may have on outcomes in overweight and obese women.A twelve-week, randomized-controlled trial was conducted using premenopausal overweight/obese (BMI > 24.9 kg/m2) adult Singapore women (n = 92) divided into three groups (exercise with synchronous, asynchronous, and no music, respectively). Pre-post clinical examinations, anthropometric, and fitness evaluations were conducted. Statistical analyses revealed that physical activity was effective in all groups with music or non-music.

Experimental Investigation Examining The Effects Of Acute Exercise On Implicit Memory Function, Paul D. Loprinzi, Morgan Gilbert, Gina Robinson, Briahna Dickerson
Experimental Investigation Examining The Effects Of Acute Exercise On Implicit Memory Function, Paul D. Loprinzi, Morgan Gilbert, Gina Robinson, Briahna Dickerson
Faculty and Student Publications
© 2019, PsychOpen. All rights reserved. Emerging work suggests that acute exercise can enhance explicit memory function. Minimal research, however, has examined whether acute exercise is associated with implicit memory, which was the purpose of this study. Three separate experimental studies were computed (N = 120; Mean age = 21). In Experiment 1, participants were randomly assigned to either a moderate-intensity bout of acute exercise (15-minute) or engaged in a seated control task (15-minute), followed by the completion of a word-fragmentation implicit memory task. Experiment 2 replicated Experiment 1, but instead employed a higher-intensity exercise protocol. For Experiment 3, participants …

Neurology Faculty Publications
BACKGROUND: Disparate research sites using identical or near-identical magnetic resonance imaging (MRI) acquisition techniques often produce results that demonstrate significant variability regarding volumetric quantification of white matter hyperintensities (WMH) in the aging population. The sources of such variability have not previously been fully explored.
NEW METHOD: 3D FLAIR sequences from a group of randomly selected aged subjects were analyzed to identify sources-of-variability in post-acquisition processing that can be problematic when comparing WMH volumetric data across disparate sites. The methods developed focused on standardizing post-acquisition protocol processing methods to develop a protocol with less than 0.5% inter-rater variance.
RESULTS: A series …
Effects Of Intertidal Position On Metabolism And Behavior In The Acorn Barnacle, Balanus Glandula, Kali Horn
Effects Of Intertidal Position On Metabolism And Behavior In The Acorn Barnacle, Balanus Glandula, Kali Horn
Master's Theses
The intertidal zone is characterized by persistent, tidally-driven fluctuations in both abiotic (e.g., temperature, [O2], salinity) and biotic (e.g., food availability, predation) conditions, which makes this a very physiologically challenging habitat for resident organisms. The magnitude and degree of variability of these environmental stressors differs between intertidal zones, with the most extreme physiological stress often being experienced by organisms in the high intertidal. Given that many of the fluctuating conditions in this environment are primary drivers of metabolic rate (e.g., temperature, [O2], food availability), we hypothesized that sessile conspecifics residing in different tidal zones would exhibit …

Mayhew, Alex Silva Ribeiro, Edilson Serpeloni Cyrino
International Journal of Exercise Science
International Journal of Exercise Science 12(4): 1187-1197, 2019.The aim of this study was to compare the acute effects of four resistance-training (RT) exercise orders on rate of perceived exertion (RPE) and RT variables with exercise load properly adjusted according to its position within the sequence in older women. That is, the load was adjusted so that it was possible that the sets were performed within the repetition-zone established. Fifteen trained older women (67.4 ± 5.3 years) participated in a crossover-design, combining single-joint (SJ) and multi-joint (MJ) exercises for upper- (UB) and lower-body (LB) in the following exercise orders: SEQA …

Metabolic And Cardiovascular Responses On A Novel, Whole Body Exercise Device Compared To A Cycle Ergometer, Melody A. Gary, Brian K. Mcfarlin
International Journal of Exercise Science
International Journal of Exercise Science 12(2): 1206-1215, 2019. The purpose of this study was to compare the metabolic effects during a similar bout of exercise on a novel, whole body exercise device (Fish and Kangaroo Machine; FKM) and a cycle ergometer. Recreationally active men and women (n =13) completed two exercise sessions. The exercise protocol included intervals alternating between exercise (3-min) and rest (3-min) for a total duration of 39-min. The exercise intensity between the two modes was matched based on heart rate response. Heart rate, cardiac output, and stroke volume were measured using a wireless telemetry technique (Physioflow …

International Journal of Exercise Science
International Journal of Exercise Science 12(2): 1198-1205, 2019. The physical demands of soccer combined with the rigor of the competitive season may have a substantial impact on autonomic modulation in field soccer athletes. The number of sudden death cases associated with soccer may be related to the physical training required to maintain performance and fitness, minimal time for recovery, and recurrent game participation. It is possible to identify individuals at risk of cardiovascular events by measuring heart rate variability (HRV), which is an indirect method for assessing autonomic activity. Therefore, the objective of this study was to analyze HRV before …
Action Potential Subpopulations In Human Muscle Sympathetic Nerve Activity: Discharge Properties And Governing Mechanisms, Stephen A. Klassen
Action Potential Subpopulations In Human Muscle Sympathetic Nerve Activity: Discharge Properties And Governing Mechanisms, Stephen A. Klassen
Electronic Thesis and Dissertation Repository
What discharge properties are expressed by varying-sized sympathetic action potential (AP) subpopulations active under baseline conditions in humans and what are the governing mechanisms? To address this overall question the microneurographic approach was employed to record multi-unit muscle sympathetic nerve activity (MSNA), after which a continuous wavelet transform exposed APs in the recorded neurogram. Study One examined the role of the paravertebral ganglia on sympathetic neural discharge patterns. Through trimethaphan infusion under baseline conditions, this study revealed ordered de-recruitment of larger to smaller AP clusters, suggesting that the paravertebral ganglia contribute to the distribution of firing probabilities expressed by differently-sized …

Mechanisms That Limit Oxidative Phosphorylation During High-Intensity Muscle Contractions In Vivo, Miles F. Bartlett
Doctoral Dissertations
Skeletal muscle oxidative capacity plays a critical role in human health and disease. Although current models of oxidative phosphorylation sufficiently describe skeletal muscle energetics during moderate-intensity contractions, much is still unknown about the mechanisms that control and limit oxidative phosphorylation during high-intensity contractions. In particular, the oxygen cost of force generation is augmented during exercise at workloads above the lactate threshold. Presently, it is unclear whether this augmentation in muscle oxygen consumption is driven by increased rates of oxidative ATP synthesis (ATPOX) or by decreases in the efficiency of ATPOX due to mitochondrial uncoupling. To address this …
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 …

Tracing Nutrient Sources To Lipid Production In Birds And Insects Using Stable Isotope (Δ13c, Δ2h) Tracers: Implications For Nutritional Physiology Of Migratory Species, Libesha Anparasan
Electronic Thesis and Dissertation Repository
Using stable isotope measurements of inert tissues to determine origins and migratory patterns is well established. However, isotopically determining nutritional origins of lipids, the primary fuel of migration, has not been attempted. I explored isotopic links between diet and stored lipids in captive White-throated Sparrows (Zonotrichia albicollis) and true armyworm moths (Mythimna unipuncta) using δ13C and δ2H measurements. Isotopic discrimination between body lipids and diet was established as linear calibration functions. Isotopic uptake following a diet switch in moths was used to trace lipid accumulation over time. Isotopic correlations between breath metabolic …

Electronic Thesis and Dissertation Repository
Rising CO2 may warm northern latitudes up to 10 °C by the end of the century. However, responses of plant physiological processes (such as photosynthesis and respiration) and growth to climate change remain uncertain. Seedlings and mature trees of tamarack (a deciduous species) and black spruce (an evergreen species), North America dominant conifers, were exposed to combined warming (up to +9 ˚C) and elevated CO2 (up to +300 ppm). In seedlings, stomatal conductance (gs) tended to increase with warming in tamarack seedlings, while gsdeclined with warming in spruce. In both species, CO2 had …

International Journal of Exercise Science
International Journal of Exercise Science 12(5): 1179-1186, 2019. Approximately 51% of American adults do not meet weekly physical activity (PA) recommendations. Pokémon Go (PoGo) popularity and its required PA participation shows potential for improved daily PA. The primary aim of this study was to objectively measure daily energy expenditure (DEE) of PoGo players and identify whether DEE differs from non-players. A secondary aim was to assess potential motivational factors to play PoGo. Local Middle Tennessee participants (n= 25) were identified as "players" or "non-players" based on current PoGo usage from August till November 2016. Participants donned a SenseWear …

Assessing Physical Activity Levels And Motivation In An Urban Midwest Private Liberal Arts College, Michael A. Kantor, Ana Freire Ribeiro
International Journal of Exercise Science
International Journal of Exercise Science 12(4): 1169-1178, 2019. Recent research indicates that over one third of U.S. adults are obese and 51.6% of adults meet the recommended 2008 physical activity (PA) guidelines. In this context, understanding what makes people engage or not in PA becomes of key importance when attempting to prevent obesity and its related comorbidities. The objective is to assess the PA and motivation levels of students, faculty, and staff in an urban Midwest Private College. Participants completed an anonymous online survey (n=119) on PA and Exercise Motivation. Fitness levels were tested and obtained from wellness assessments (n=74). …
