Parasite Prevalence And Innate Immunity In Mud And Musk Turtles, Nicole Beckett
Honors Program Theses
Turtles are being infected by both ectoparasites (typically leeches) and endoparasites (typically blood parasites). It is unknown what the parasite intensity is of wild Central Floridian turtles is, and what effect this parasite load has on them. In order to determine these factors wild turtles (Sternotherus odoratus, Kinosternon baurii, and Kinosternon subrubrum) were caught from two locations, Mead Botanical Gardens, and Lake Virginia. Hoop traps were used to catch the turtles, which were then sampled and released. Captured turtles went through a series of measurements as well as a blood draw before release. Blood parasite levels were taken from the …

Crayfish Tube-Feeding Methodology, Phoenix Johnson
Williams Honors College, Honors Research Projects
The purpose of this paper was to use a tube feeding method on crayfish to expose them to substances through ingestion rather than the gill. This was done to mimic human ingestion of substance to aid in crayfish research involving substances that are normally ingestion. This was done by using a pipette to inject grains of sand into the mouth of the crayfish. To determine if the method worked and successfully went into the stomach the grains of sand were recovered and counted under a microscope after certain increments of time post injection.

Rift Valley fever virus (RVFV) is a negative-sense virus that was first described in 1930 when it was isolated from sheep during an outbreak. In the last 25 years there has been a spread in the geographical range into the Middle East. The most susceptible animals are cattle, goats, sheep, and camels. The most overt symptom of livestock infection is that infected pregnant animals experience spontaneous abortion. Humans are susceptible as well and symptoms range from mild febrile illness to liver necrosis, blindness, hemorrhagic fever, and death. An important player in the cellular innate response to RVFV infections is the …

Biodistribution Comparison Of Fentanyl And Morphine Following Acute And Repeated Expsoure, Rosamond M. Goodson
Theses and Dissertations
The ongoing opioid crisis constitutes a dire public health threat that has resulted in staggering loss of life. In 2021, opioids were implicated in over 75% of the approximately 107,000 deaths attributed to drug overdose (CDC), and synthetic opioids such as fentanyl and its analogues are key drivers of the surge in opioid fatalities in recent years. Although fentanyl is a μ opioid receptor agonist, it has several distinct attributes compared to other drugs in this category, such as morphine. These include enhanced lipophilicity, heightened potency to induce respiratory depression, more rapid entry into the central nervous system, reduced sensitivity …

Mild Traumatic Brain Injury In Yucatan Minipigs: Assessing Changes In Approachability And Mechanical Nociception Following Diffuse Central Fluid Percussion Injury, Mark D. Pavlichenko
Theses and Dissertations
Traumatic brain injury (TBI) is a major healthcare concern affecting millions. Symptoms of TBI include sensory sensitivity and social changes that may persist long-term. Due to similarities in cytoarchitecture, metabolism, and inflammation, higher order minipig models are advantageous for translational TBI research, however, there remains a shortage of information regarding their behavioral and sensory sequelae following injury. Therefore, in this study, we assessed changes in sociability and somatosensation in adult male and female Yucatan minipigs for up to one-week following a sham or central fluid percussion injury (cFPI). Specifically, the voluntary human approach task (VHAT) and the forced human approach …

Tim/Tam Receptors: A Potential Biomarker For Predicting Sensitivity To Zika Virus-Induced Oncolysis In Non-Small Cell Lung Cancers, Shankari Somasekar
Honors Undergraduate Theses
Non-small cell lung cancers (NSCLC) constitute 80-85% of lung cancers and are the leading cause of cancer-related deaths globally. The most common cause is prolonged smoking. Current treatment options for NSCLC include surgery, radiation, chemotherapy, targeted drug therapy, and immunotherapy. Although these medications are effective in the short term, patients often face issues of drug resistance and debilitating side effects with prolonged use. Currently, the use of Zika virus (ZIKV) is being researched as a possible alternative treatment for cancer, which minimizes side effects and the risk of drug resistance. TIM/TAM proteins are identified as the putative ZIKV receptors on …
Modulation Of Persistent Inward Currents With Changes In Posture And Cutaneous Sensory Input,

Modulation Of Persistent Inward Currents With Changes In Posture And Cutaneous Sensory Input, Ryan William Weller
Theses and Dissertations (Comprehensive)
Spinal motor neuron (MN) persistent inward currents (PIC) increase and sustain the MN output. PIC is amplified by descending monoamines and reduced by afferent inhibition. There is strong coupling between plantar cutaneous sensory input and lower limb MNs. Given that monoaminergic drive is altered with postures and motor tasks, our purpose was to assess posture-dependent plantar cutaneous sensory modulation of tibialis anterior (TA) MNs. We hypothesize that: 1) a supine position will suppress PIC, 2) removing the load from the bottom of the heel will inflate PIC, and 3) cutaneous stimulation of the plantar aspect of the heel will reduce …

Graduate Theses, Dissertations, and Problem Reports (ETD)
The neural mechanisms that control the onset of puberty are not completely understood. In livestock, the onset of puberty relies on an increase in gonadotropin releasing hormone (GnRH) and luteinizing hormone (LH). Kisspeptin, neurokinin B, and dynorphin neurons (KNDy) and their receptors, Kiss1r, NK3R, and KOR, respectively, are important regulators of puberty. Previous data from our laboratory has shown that KNDy neurons may be responding to other inputs, including the melanocortin system, that will affect the timing of puberty. Given this, we examined kisspeptin receptor (Kiss1r) mRNA expression in GnRH neurons as well as examining melanocortin 3 and 4 receptor …

The objective of this study is to fabricate solid-contact ion selective electrodes (SC-ISEs) that have long term stable potential. Various conducting polymers such as polyaniline and its derivatives have been successfully employed to improve the potential stability in SC-ISEs. Recently, the role of hydrophobicity at the interface between the conducting polymer solid contact and the ion sensing membrane has been investigated and figured out that the hydrophobic interfaces preclude water layer formation that deteriorate the SC-ISEs potential stability and reproducibility. In this work, a hydrophobic polyaniline derivative was fabricated on the surface of a glassy carbon electrode by electropolymerization of …
