Uptake And Localization Of Poly(2-Vinyl-4,4-Dimethyl Azlactone) Modified With Rhodamine- And Coumarin-Based Molecules In Human Embryonic Kidney (Hek293) Cells, Garrett Tassin May 2023

Uptake And Localization Of Poly(2-Vinyl-4,4-Dimethyl Azlactone) Modified With Rhodamine- And Coumarin-Based Molecules In Human Embryonic Kidney (Hek293) Cells, Garrett Tassin

Honors Theses

Fluorescence microscopy is a bioimaging technology that utilizes the excitation and emission of fluorophores to identify cellular structures, processes, and interactive events. Natural and synthetic organic dyes are frequently used in fluorescence microscopy techniques for imaging, therapeutic, and biomedical applications. It is also employed in the development of novel organic dyes for innovative methods of drug delivery and labelling. In this study, we investigate the behavior of an organic dye consisting of the post-polymerization modification of poly(2-vinyl-4,4-dimethyl azlactone) (PVDMA) with tetramethyl rhodamine cadaverine (TMR) and a coumarin-based molecule (DBAC). Using cultured HEK293 cells and fluorescence confocal microscopy, we show the …


Validity Of The Loadsol Pro Insole For Pedal Reaction Force Measurements During Stationary Cycling, Anabelle Vallecillo Bustos May 2023

Validity Of The Loadsol Pro Insole For Pedal Reaction Force Measurements During Stationary Cycling, Anabelle Vallecillo Bustos

Honors Theses

Advancements in wearable technology have allowed clinicians, coaches, and researchers the ability to observe and quantify human movement outside the laboratory. Instrumented insoles are an example of novel technology that can be worn in the shoes and measure vertical reaction force wirelessly. The use of such insoles will prove to be beneficial for athletes as they train, patients as they progress through rehabilitation, and researchers as they experiment in their respective fields. The Loadsol Pro (Novel Inc., St Paul., MN, USA) has been shown to produce accurate and reliable measures of ground reaction forces (GRF) in various dynamic activities including …


Pirna Expression In Regenerative Tissue Of Octopus Bimaculoides, Bailey Ervin May 2023

Pirna Expression In Regenerative Tissue Of Octopus Bimaculoides, Bailey Ervin

Honors Theses

Tissue regeneration is present in varying capacities across the animal kingdom. Animals such as Hydra and planarians have the capacity to regenerate entire bodies from extremely small sections of amputated tissue. Others, such as humans, have restricted capacities of regeneration, especially in terms of full appendages and specialized tissues such as cardiac and nervous tissue. One of the primary goals of studying regeneration in other organisms is to achieve the development of regenerative medicine. Interaction of P-element induced WImpy testis (PIWI) proteins and PIWI-interacting RNAs (piRNAs) have been implicated in germline genome maintenance, as well as transposable element silencing. Research …


Assessing Athletes’ Risk For Developing The Female Athlete Triad At Two Mississippi Universities, Laura G. Warren May 2023

Assessing Athletes’ Risk For Developing The Female Athlete Triad At Two Mississippi Universities, Laura G. Warren

Honors Theses

Despite the health benefits associated with regular exercise, some female athletes experience menstrual dysfunction and low bone mineral density associated with low energy availability as a result of a high volume of exercise and inadequate caloric intake; these three components characterize the female athlete triad (FAT). Prior research explored the severity of the FAT, pre-season screenings, and nutrition intervention methods; however, current research regarding the relationship between the risk for developing the FAT and access to nutrition resources is lacking. The purpose of this study was to assess the risk of female athletes at two Mississippi universities for developing the …


Pirna Expression In The Tube Feet Of Lytechinus Variegatus, Reagan Milliet May 2023

Pirna Expression In The Tube Feet Of Lytechinus Variegatus, Reagan Milliet

Honors Theses

Tissue regeneration is an area of research with implications for medicine and animal health. While nearly all living multi-cellular organisms are capable of regeneration, there are major differences in the animal kingdom. Some organisms are capable of regenerating virtually every cell in their bodies. In hopes of engineering tissue regeneration for medical applications, the mechanisms by which organisms regenerate are being widely investigated. To better understand regeneration, the role of P-element Induced WImpy testis (PIWI) proteins are being evaluated. In collaboration with PIWIinteracting RNAs (piRNAs), PIWI proteins have been proven instrumental to transposon silencing and maintenance of the genome in …


Development Of A Novel Environmental Dna (Edna) Tool For Monitoring Vulnerable Freckled Guitarfish, Pseudobatos Lentiginosus, In The Western Central Atlantic, Sarah Toepfer May 2023

Development Of A Novel Environmental Dna (Edna) Tool For Monitoring Vulnerable Freckled Guitarfish, Pseudobatos Lentiginosus, In The Western Central Atlantic, Sarah Toepfer

Honors Theses

Rhino-rays are the most threatened group of elasmobranchs, having experienced widespread declines due to mortalities in fisheries and habitat degradation. Within the Western Central Atlantic, there are two extant species of Rhino-rays, the Critically Endangered Smalltooth Sawfish, Pristis pectinata, and the Vulnerable Freckled Guitarfish, Pseudobatos lentiginosus. Although there is research committed to P. pectinata in this region, less is known about the distribution status of P. lentiginosus. Over the past 50 years, P. lentiginosus have undergone a presumed range contraction in U.S. waters; once found from North Carolina to Texas, and historically common in the north central …


Variations In Thermoregulation Strategies Of Northern And Southern Populations Of Mischocyttarus Mexicanus, Taylor Guild May 2023

Variations In Thermoregulation Strategies Of Northern And Southern Populations Of Mischocyttarus Mexicanus, Taylor Guild

Honors Theses

Mischocyttarus mexicanus is a species of eusocial paper wasp that is found across much of the Southeastern coastal region of the United States. Contrasting wintering strategies have been seen in northern versus southern populations. Anecdotally, northern populations overwinter by clustering on top of palmetto fronds, their preferred nesting substrate, in a sort of "taco" shape, while southern populations stand on their nests that hang on the underside of the palmetto frond throughout the year. I tested three hypotheses related to the adaptive value of northern over-frond clustering behavior: 1) Over-frond clustering is thermoregulation related, meaning it would be temperature driven. …


Impact Of Training Volume On Female Athlete Triad Risk For Female Collegiate D1 Track And Field Athletes, Sarah Parnell May 2023

Impact Of Training Volume On Female Athlete Triad Risk For Female Collegiate D1 Track And Field Athletes, Sarah Parnell

Honors Theses

iv ABSTRACT The Female Athlete Triad is the joint-presentation of three intertwined conditions (i.e., low energy availability (LEA), low bone mineral density (BMD), and menstrual dysfunction) that range in severity across affected individuals and have been known to affect the mental, emotional, and physical health of female athletes in a number of sports, especially those that are leanness-orientated and feature a high prevalence of disordered eating. The purpose of this study is to assess the potential relationship between increasing amounts of training volume and individual Triad risk factors in women’s collegiate track and field. Online Qualtrics surveys were administered to …
