Morphological Variation Of Lingual Glands In Wild American Alligator (Alligator Mississippiensis) Populations, Benjamin Angalet

Master's Theses

American alligators (Alligator mississippiensis) inhabit diverse aquatic ecosystems including freshwater wetlands, swamps, and estuarine rivers. As apex predators, their physiological resilience has implications for ecosystem stability and long-term conservation. With projected sea-level rise and increasing saltwater intrusion into coastal freshwater habitats, understanding the osmoregulatory capacity of alligators is increasingly important. Unlike marine-tolerant crocodilians such as the saltwater crocodile (Crocodylus porosus), which possess specialized salt-secreting lingual glands in addition to renal and cloacal mechanisms, the morphology and physiological significance of lingual glands in wild American alligators remain poorly understood. This study examined lingual gland morphology and plasma …

The Impact Of Growth Hormone-Releasing Hormone Antagonist On Human Adipose-Derived Stem Cells, Jeanne Michelle Dugas

Master's Theses

Obesity is a condition that affects over 40% of American adults and contributes to numerous preventable health issues. This condition is caused by increased adipose tissue, which forms when stem cells transform into adipocytes. Mesenchymal stem cells, including human adipose-derived stem cells (hASC), are multipotent with the ability to differentiate into adipocytes, osteocytes, or chondrocytes. Many factors affect this transformation, including the peptide growth hormone-releasing hormone (GHRH). The main role of GHRH is to trigger the release of growth hormone, but it has also been found to play an important role in adipocyte metabolism. We expect that if the differentiation …

The Antioxidant Potential Of Rosemary Leaf-Derived Nanovesicles, Shani Akila Griffin

Master's Theses

Human dermal fibroblasts are essential for maintaining skin homeostasis. However, exposure to exogenous and endogenous stressors can lead to fibroblast instability, extracellular matrix degradation, and excessive reactive oxygen species (ROS) production. These factors contribute to skin aging and ROS-induced skin disorders leading to hair loss. Adverse effects from synthetic treatments have driven interest in natural alternatives like plant extracts for skin therapy. However, the polyphenols in these treatments require an effective delivery system to ensure their stability and targeted application. Plant derived nanovesicles (PDNVs) are emerging as a promising natural alternative for therapeutic applications. Their biocompatibility, stability, and encapsulated compounds …

Does Limb Specialization In Track And Field Introduce Asymmetry In Dynamic Stability?, Aaron X. Jones

Master's Theses

Time to stabilization (TTS) represents the time it takes for a person to become still after a hop landing. Lower times suggest greater dynamic stability. Whereas leg dominance (preference) does not seem to have a significant impact on TTS performance in the general healthy populations, limb specialization in sport may introduce asymmetry. This study compares TTS following forward hops in healthy male controls (N = 19) to varsity DIII Track & Field athletes (N = 20). Groups were equal for height, but the athlete group’s average limb length (106.7 ± 5.5 cm) was greater than the control group (101.5 ± …

Impacts Of Temperature Acclimation On Swimming Performance And Metabolic Dynamics Of The Amargosa River Pupfish, Cyprinodon Nevadensis Amargosae, Teresa E. Guerre

Master's Theses

Climate change is leading to warmer atmospheric temperatures in many regions of the world, which in turn is raising the temperatures of aquatic habitats and simultaneously shifting the frequency and severity of extreme precipitation events. In fishes, metabolic demands are higher under warmer conditions, while dissolved oxygen levels typically decline in warmer water. This mismatch may limit the ability of fishes to cope with high water flow events like floods that can occur following extreme rainfall. A few species of pupfishes (genus Cyprinodon) in the Death Valley region of California and Nevada, USA, occupy stream or river habitats with …

This study lays the groundwork for …

The Effects Of Conditional Loss Of Myosin Binding Protein H-Like On Cardiac Function, Hope Victoria Burnham

Master's Theses

Dilated cardiomyopathy (DCM) is a common cause of heart failure with a strong hereditary component. Mutations in the myosin-binding protein H-like (MYBPHL) gene are linked to hereditary DCM, atrial fibrillation, and atrioventricular arrhythmias. MyBP-HL is a sarcomeric protein that is highly expressed in the atria with only scarce, distinct clusters of MyBP-HL positive cells in the ventricles, mostly in or surrounding the ventricular conduction system (VCS). Constitutive knock-out of MyBP-HL in mice causes atrial dilation, ventricular dysfunction, arrhythmia, and DCM. Whether MyBP-HL plays a developmental role, or if knock-down in adulthood will recapitulate a similar phenotype has yet to be …

Patterns And Potential Mechanisms Of Phenotypic Changes In Urban Small Mammals, Leslie Lopez

Master's Theses

Urbanization is an example of human induced rapid environmental change that can have wide-reaching ecological effects, including habitat destruction, fragmentation, and alteration of local climates. Effects of urbanization have been shown to impact wildlife, as disturbances resulting from urbanization can create novel environments and selective pressures that could lead to changes in morphology, physiology, or both. Small mammals such as rodents are an ecologically important set of wildlife species because they are a key prey item for several predators, hold strong influence over plants as a primary consumer, and some species carry and transmit major human and animal diseases. Previous …

The Role Of B Cell Activation State And Sex In Aryl Hydrocarbon Receptor Mediated Induction Of Chemokine Receptor 9 And Alpha4beta7 Expression In Vitro, Logan Bauerle

Master's Theses

Defense of mucosal tissues from microbial infection and allergy is reliant on continual production of antibodies. The aryl hydrocarbon receptor (AhR) is known to regulate B cell development and is associated with suppression of systemic humoral immunity. Recent attention has been paid to the role of the AhR in altering expression of cell adhesion molecules (CAMs). B cells express CAMs and chemokine receptors to migrate around the body for localized secretion of antibodies. AhR agonists promote B cell migration to the small intestine through upregulation of chemokine receptor 9 (CCR9) and integrin α₄β₇. Both the AhR …

Characterization And Estimation Of Musculoskeletal Pain Using Machine Learning, Boluwatife Faremi

Master's Theses

Traditional scales utilized for recording pain are known to be highly subjective and biased due to inaccuracies in recollecting actual pain intensities. As a result, machine learning (ML) models that are trained using these scores as ground truth are reported to have low performance for objective pain classification because of the huge disparity between what was felt in moments of pain and the scores recorded afterward.

In the present study, two devices were designed for gathering real-time, continuous in-session subjective pain scores and the recording of the autonomic nervous system (ANS) altered endodermal (EDA) activity. 24 participants were recruited to …

Southern Sea Otter (Enhydra Lutris Nereis) Fur Morphology, Thermal Function, And Buoyancy Across Ontogeny, Kate Riordan

Master's Theses

Sea otters (Enhydra lutris) have the densest fur of any animal, and the hairs function to trap a layer of air that is used for insulation. When a sea otter is born, it has a natal pelage (baby fur), and sea otters eventually molt that fur and replace it with a pelt resembling the adult fur. Sea otter fur is composed of 3 types of hairs: underhairs, intermediate hairs, and guard hairs. Sea otters are more susceptible to the negative effects of oiling from oil spills compared to other marine mammal species because they solely rely on fur …

Hydric Physiology Of Lizards, Savannah Weaver

Master's Theses

Chapter 1: Animals can respond to extreme climate by behaviorally avoiding it, or by physiologically coping with it. We understand behavioral thermoregulation and physiological thermal tolerances, but water balance has largely been neglected. Climate change includes both global warming and changes in precipitation regimes, so improving our understanding of organismal water balance is increasingly urgent. We assessed the hydric physiology of endangered Blunt-nosed Leopard Lizards (Gambelia sila) by measuring cutaneous evaporative water loss (CEWL), plasma osmolality, body mass, and body condition throughout their active season. On average, G. sila had low CEWL that is likely desert-adaptive, and high …

Effects Of Intertidal Position On The Response To Oxygen And Desiccation Stress In The Common Acorn Barnacle, Balanus Glandula, Megan M. Dotterweich

Master's Theses

Sessile invertebrates in the rocky intertidal experience intermittent periods of air exposure due to tidal flux, presenting risks of temperature extremes, hypoxia, nutrient limitation, and most dangerously, desiccation. Microscale variation in severity and frequency of these risks is widely dependent on vertical position within the intertidal zone. Common acorn barnacles (Balanus glandula) have a wide vertical distribution in the intertidal, creating large differences in microhabitat between the highest and lowest individuals in the population. This study set out to explore whether tidal position dependent differences exist in the response to oxygen and desiccation stress in B. glandula. …

A Proof Of Concept For Detection Of Palato-Lingual Contact Without Intraoral Electrodes In A Human Participant, Amitava Biswas

Master's Theses

The author of this thesis conceived and investigated an unexpected electrical signal that may not be noticed during regular electroglottography (EGG) when electrodes are conventionally placed on the anterior surface of the throat. It appears that there is a measurable electrical signal from the EGG equipment when electrodes are placed over the frontal cheek (belly of zygomatic muscle), and the tongue is elevated to contact the hard palate, or the tongue is lowered to break the contact. Therefore, this phenomenon is designated as unconventional electroglottography (UEGG, Dr. Steven Cloud, private communication, July 17, 2022).

Two distinctive patterns of waveforms were …

Ankle Dorsiflexion Range Of Motion, Dynamic Balance, And Static Balance In Division Iii Collegiate Gymnasts, Emily Sabo

Master's Theses

Introduction: Artistic gymnastics is a demanding sport composed of high intensity activities. Decreased range of motion can increase the risk of lower extremity injury due to the inability to disperse forces properly upon landing. Landing from a height demands dynamic balance, which may be influenced by ankle range of motion. Due to the complexity of the sport, identifying potential deficits at the ankle could lead to the development of injury prevention programs. Purpose: The purpose of this study is to investigate if correlations exist between active ankle dorsiflexion range of motion (AROM) and static balance and/or AROM and dynamic balance …

The Effects Of A Loaded Pre-Competition Activity Using Tethered Swimming On 25-Yard Swim Sprint Performance 2021, Jacob Burchfield

Master's Theses

Warmup is a standard practice for swim competitions, but there is minimal scientific evidence regarding the effectiveness of pre-competition activities (PCA) after the swim warmup. This study examined whether a loaded PCA using tethered swimming while attached to a power rack improves performance in a 25-yard swim sprint. Post activation performance enhancement (PAPE) may be the proposed mechanism for improvement resulting from a loaded PCA. To determine if PAPE existed following the loaded PCA, varsity swimmers from SUNY Cortland performed a 25-yard sprint a loaded PCA and after an unloaded PCA (control). All participants performed a standard meet warmup (1600-yards) …

An Investigation Of Stress-Related Factors And Injury Occurrence In Division Iii Ice Hockey Athletes 2020., Christian Kiesel

Master's Theses

Many variables can factor into a student athlete sustaining an injury, but one of the most interesting is stress. The Stress and Injury Model is excellent in explaining how exactly history of stressors, personality, and coping mechanisms play a pivotal role in the stress response. If these three factors cause a negative stress response, then that will lead to an athlete becoming more likely to become injured. This study used 40 ice hockey players from a Division III NCAA institution. Each participant completed the Inventory of College Students’ Recent Life Experiences (ICSRLE) and Pittsburgh Sleep Quality Index (PSQI) every month …

Balance and postural control exercises are often a part of exercise programs. During exercise programs, movement practitioners can provide instructions to facilitate performance and learning. Instructions can be used to direct attentional focus, which has been found to affect the performance and learning of motor skills, including balance and postural control tasks. However, no known studies to date have investigated the effect of both internal and external attentional focus instructions on static single leg balance performance. The purpose of this study was to investigate the effect of attentional focus instructions on static single leg balance performance as reflected by the …

A Comparison Of Power Variables For Two Loading Methods In Weighted Vertical Jumps 2020, Jonathan Tanguay

Master's Theses

Training exercises to develop muscular strength and power, such as the weighted jump squat, commonly utilize barbells and dumbbells to increase resistance. Strength coaches often measure improvements in peak force, peak power, and rate of force development to determine effectiveness of a training program. The purpose of this study was to determine if equipment selection (barbells vs. dumbbells) affects peak force, peak power, and/or rate of force development in weighted jump squats. Thirteen physically active, college-aged males (age: 21.6 ± 2.0 years, height: 182.8 ± 9.7 cm, body mass: 87.2 ± 9.0 kg, lean mass: 72.3 ± 8.1 kg) performed …

Behavioral Ecology And Physiological Health Of Managed Populations Of Juvenile Blanding's Turtles (Emydoidea Blandingii) In Urban Wetlands, Armand Andre' Cann

Master's Theses

Substantial threats to reptile species biodiversity have become apparent in the last few decades. This is partly caused by significant losses in grasslands and their associate prairie-wetland ecosystems. One Midwestern prairie-wetland species, Blanding's Turtles (Emydoidea blandingii), are at risk of extirpation due to habitat loss, fragmentation, and increased predator populations. Consequently, significant head-starting efforts, a form of reintroduction conservation using captive-reared and then released turtles, have been conducted to recover populations of E. blandingii in northeastern Illinois. However, the success of these programs both locally and range-wide have not been fully quantified. Unfortunately, many approaches to guaging success involve long-term …

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 …

The Proteomic Response Of Northern Elephant Seal (Mirounga Angustirostris) Pups To Physiological Stress During Development, Melissa P. Voisinet

Master's Theses

Background: Northern elephant seals transition from terrestrial nursing pups to pelagic foraging juveniles in a short period of just 8-12 weeks. During the post-weaning period, pups rely solely on the energy reserves gained during nursing for their caloric demands and water supply. The prolonged absence of food after weaning is the first of many fasts for which the seals have evolved adaptations such as decreased urine production and increased blubber reserves. The stressors experienced from learning to dive for the first time are also stressors that they will experience frequently as an adult and for which they have evolved adaptations. …

The Effects Of Salinity On Zootechnical Performance Of Spotted Seatrout (Cynoscion Nebulosus) In Recirculating Aquaculture Systems, Eric Gigli

Master's Theses

The spotted seatrout (Cynoscion nebulosus) is a euryhaline finfish candidate for marine aquaculture in the northern Gulf of Mexico. Aquaculture of this species currently uses salinities of 25 psu or greater making production challenging in areas where high salinity water is not available. This study aimed to document the effects of salinity on zootechnical performance of spotted seatrout embryos, early larvae, and juveniles in recirculating aquaculture systems to assist with the development of protocols for low salinity culture.

Embryos obtained from a volitional spawn at 29 psu were incubated at three salinities (12.5, 18.75, or 25 psu) until …
