Relationships Between Vertical Ground Reaction Forces And Clubhead Velocity In Ncaa Division I Female Golfers, Jared Bush
Honors Theses
Golf biomechanics research has focused on clubhead velocity (CHV) for over a decade with the intent of discovering the physical attributes that contribute the most to CHV. Previous research has displayed the significant correlations of strength and power attributes to CHV, giving evidence for practitioners to integrate training to improve these attributes. Recent studies have referenced vertical ground reaction forces (vGRF) and how they affect CHV. In this study, vGRFs are tested for their correlations to CHV in NCAA Division I female golfers. Clubs of various lengths were used to determine correlations between each club and vGRFs. Correlations between CHV …
Analysis Of Ecological Tradeoffs Between Congeneric Shrimp In Coastal Mississippi Waters, Baylor K. Lynch
Analysis Of Ecological Tradeoffs Between Congeneric Shrimp In Coastal Mississippi Waters, Baylor K. Lynch
Honors Theses
Palaemonidae is an ecologically important and abundant family of shrimp that link the benthos to many estuarine food webs. Palaemon pugio and Palaemon vulgaris regularly co-occur along estuarine edge habitats despite previous studies suggesting different preferred sediment types and salinity regimes. The objective was to determine if competition is occurring between the congeners by comparing their relative abundance and assessing isotope niche space along an estuarine gradient. I seasonally sampled various edge habitats at four sites throughout Biloxi Bay, MS, using fyke nets fished over a tidal cycle from November 2020 to November 2021. Collected organisms were identified to the …
Invasion Properties Of Listeria Monocytogenes In Aged Cells, Mina Lane Chasteen Burton
Invasion Properties Of Listeria Monocytogenes In Aged Cells, Mina Lane Chasteen Burton
Honors Theses
Listeriosis is a bacterial infection caused by the gram-positive pathogen Listeria monocytogenes. When compared to other foodborne illnesses, listeriosis has a higher death rate due to an increased incidence of complications such as meningitis, hydrocephalus, and sepsis in immunocompromised populations. Elderly individuals experience a condition known as immunosenescence, which is a gradual compromisation of the immune system brought on by natural aging. Hutchinson-Gilford progeria syndrome (HGPS) is a rare genetic disorder causing premature aging, which allows HGPS cell lines to be used as models to further research in the field of biogerontology. This study utilizes the F2365 strain of …
Reproductive Timing In Percina Aurora And Other Percina Species In The Pascagoula River Watershed, Malia Davidson
Reproductive Timing In Percina Aurora And Other Percina Species In The Pascagoula River Watershed, Malia Davidson
Honors Theses
The Southeastern United States is home to high levels of aquatic biodiversity and was recently named one of the Earth’s biodiversity hotspots. Within this region, growing human populations continue to place pressure on aquatic ecosystems and the resident species. Darters (Percidae: Percina) represent a large proportion of the freshwater fish diversity in the region. However, for some species the fundamentals of age, growth, reproductive timing and effort, and ecology remain poorly understood. That said, understanding the timing, duration, and effort allocated to reproduction is vital to successful management of any species. The pearl darter, Percina aurora, has been …
Comparing The Reproductive Fitness Of Fundulus Hybrids And Their Parental Species (Fundulus Olivaceus And Fundulus Notatus) Within Mississippi Freshwater Contact Zones, Sarah Stovall
Honors Theses
Hybridization of closely related taxonomic groups within the Animal Kingdom has led to complex species interactions that are not well understood. Pre-zygotic or post-zygotic barriers complicate hybridization as a means to diversify; however, diverging hybrids may speciate and expedite evolution of involved taxa. This study pursues understanding of these intricate interactions using topminnow Fundulus notatus, Fundulus olivaceus, and their hybrids from the Fundulus notatus species complex. Persisting hybrids within riverine contact zones were hypothesized to experience barriers of hybrid breakdown from lower fitness in comparison to the pure species. Specimens were collected within four contact zones: Spring River, …
Oligomerization Of Amyloid-Β Peptide In The Presence Of Gangliosides–Implications For Alzheimer Disease, Sydney Boyd
Oligomerization Of Amyloid-Β Peptide In The Presence Of Gangliosides–Implications For Alzheimer Disease, Sydney Boyd
Honors Theses
Alzheimer disease (AD) is a neurodegenerative disorder that leads to memory impairment and cognitive dysfunction in elderly populations worldwide. A key characteristic of AD is the formation of neuritic plaques composed of extracellularly deposited aggregates of amyloid-β (Aβ), an intrinsically disordered protein. Although Aβ fibrils were once thought to be the prime initiators of the disease, research has since been shifted to consider soluble, low molecular weight Aβ oligomers as the driving force behind AD toxicity. Due to its origin as a cleavage product of amyloid precursor protein (APP), an integral membrane protein, Aβ is known to perpetually interact with …
Expression And Purification Of The Bacterial Protein Curli Csga And Its Cross-Interactions With Amyloid-B, Leah Grace Cantrell
Expression And Purification Of The Bacterial Protein Curli Csga And Its Cross-Interactions With Amyloid-B, Leah Grace Cantrell
Honors Theses
One of the main causes of neurodegenerative diseases is aggregation of amyloid proteins that are toxic to the neurons. Proteins like amyloid-β (Aβ) and α-syneuclein (α-syn) form hallmark aggregate lesions that contribute to pathological processes in the brain in Alzheimer and Parkinson’s patients, respectively. Recent ground-breaking studies have suggested a link between the microbiota of the gut and neurodegenerative diseases, called the “gut-brain axis.” It has been long known that the protein, CsgA found in many enteric bacteria, forms amyloid fibers of its own called Curli. Curli fibrils are a structural component of bacterial colonies and maintain the integrity of …
Retrospective Reports Of Parental Feeding Practices And Current Emotional Eating Behaviors Among College Students, Mercedes Babin
Retrospective Reports Of Parental Feeding Practices And Current Emotional Eating Behaviors Among College Students, Mercedes Babin
Honors Theses
Emotional eating is a commonly reported eating behavior among United States adults; however, previous literature has indicated that the development of emotional eating is abnormal with regard to the body’s typical physiologic functioning. Although several studies have shown parental feeding practices correlate to the development of emotional eating in children, little research has been done to explore the association between parental feeding practices experienced in childhood and eating behaviors present in adulthood. The purpose of this study was to explore the relationship between parental feeding practices in childhood (i.e., food as a reward, monitoring, restriction, and pressure to eat) and …
Habitat Preference Of F. Notatus And F. Olivaceus From A Reversed Hybrid Zone, Elizabeth Hart Williams
Habitat Preference Of F. Notatus And F. Olivaceus From A Reversed Hybrid Zone, Elizabeth Hart Williams
Honors Theses
Understanding the mechanisms driving habitat preference throughout an organism’s life opens doors to the further understanding of the origins of diversity. Two species of minnow, Fundulus notatus and Fundulus olivaceus, are ideal for ecological research on habitat preference. Ordinarily, F. notatus and F. olivaceus display habitat preferences of downstream and upstream, respectively, with minimal coexistence at confluences. However, in some drainages, these preferences are flipped, like those in the Tombigbee River basin. Members of both species were collected from the Tombigbee River, tagged with species and sex specific colored elastomer marks, and placed in either a homogeneous control or …
