Dietary Analysis For Hashimoto’S Thyroiditis: An Integrative Review, Evan Thompson, Alison Hultquist

Master of Science in Nursing Final Projects

Abstract

Hashimoto’s Thyroiditis (HT) is the leading cause of primary hypothyroidism in the United States. In HT, there is an infiltration by lymphocytes which leads to the production of autoantibodies against the thyroid gland. Throughout this integrative review, the aim was to evaluate the effectiveness of micronutrient supplementation and dietary management as adjunct treatments in HT. The purpose was to assist primary care providers in the development of a more holistic plan of care. Literature published within the past seven years was gathered and reviewed from PubMed, CINAHL, and Cochrane Library. Findings indicate that many patients with HT may benefit …

Reactive Chemistries For Protein Labeling, Degradation, And Stimuli Responsive Delivery, Myrat Kurbanov

Doctoral Dissertations

Reactive chemistries for protein chemical modification play an instrumental role in chemical biology, proteomics, and therapeutics. Depending on the application, the selectivity of these modifications can range from precise modification of an amino acid sequence by genetic manipulation of protein expression machinery to a stochastic modification of lysine residues on the protein surface. Ligand-Directed (LD) chemistry is one of the few methods for targeted modification of endogenous proteins without genetic engineering. However, current LD strategies are limited by stringent amino acid selectivity. To bridge this gap, this thesis focuses on the development of highly reactive LD Triggerable Michael Acceptors (LD-TMAcs) …

Alcohol use disorder (AUD) produces cognitive deficits, indicating a shift in prefrontal cortex (PFC) function. PFC glutamate neurotransmission is mostly mediated by α-amino-3‑hydroxy-5-methyl-4-isoxazolepropionic acid-type ionotropic receptors (AMPARs); however preclinical studies have mostly focused on other receptor subtypes. Here we examined the impact of early withdrawal from chronic ethanol on AMPAR function in the mouse medial PFC (mPFC). Dependent male C57BL/6J mice were generated using the chronic intermittent ethanol vapor-two bottle choice (CIE-2BC) paradigm. Non-dependent mice had access to water and ethanol bottles but did not receive ethanol vapor. Naïve mice had no ethanol exposure. We used patch-clamp electrophysiology to measure …

Background: Bivalent mRNA vaccines were recommended since September 2022. However, coverage with a recent vaccine dose has been limited, and there are few robust estimates of bivalent VE against symptomatic SARS-CoV-2 infection (COVID-19). We estimated VE of a bivalent mRNA vaccine dose against COVID-19 among eligible U.S. healthcare personnel who had previously received monovalent mRNA vaccine doses. Methods: We conducted a case-control study in 22 U.S. states, and enrolled healthcare personnel with COVID-19 (case-participants) or without COVID-19 (control-participants) during September 2022–May 2023. Participants were considered eligible for a bivalent mRNA dose if they had received 2–4 monovalent (ancestral-strain) mRNA vaccine …

Monitoring The Leaching Of Bisphenol-A From Feminine Hygiene Products Using Fluorescence Spectroscopy, Madison Easley

Honors Theses

Bisphenol-A (BPA) is a compound commonly used as a stabilizer in plastic products, including food storage containers and thermal paper receipts. Because BPA can bind to and activate estrogen receptors, it is linked to reduced fertility, altered development, and hormone-related cancers. A recent study at NYU Medical School confirmed the presence of BPA in pantyliners, pads, tampons, feminine washes and deodorants. This is concerning due to the high absorption capacity of the vulvar skin.

For the research performed in our lab this summer, the goal was to determine if fluorescence spectrophotometry could be used to determine the presence of BPA …

Determining The Ideal Concentrations Of Ethanol And Propylene Glycol In Ethosomes For Transdermal Delivery Of Vitamin D3, Rebecca Conner

Harrisburg University Research Symposium: Highlighting Research, Innovation, & Creativity

Vitamin D₃ is an important chemical in the human body, however, many Americans have low levels of this vitamin. There are plenty of oral supplementations for Vitamin D₃ deficiency, but those of older age and busy schedules may struggle to meet the minimum requirement. A recently developed ethosomal transmembrane delivery system (Touitou, 2000), similar to liposomes but also containing ethanol, allows users to apply a gel dermally and have the desired drug or active ingredient reach the bloodstream faster. However, there is considerable variation in the concentration of ethanol and permeation enhancers used. Using an affordable method to …

Ca2+-Regulated Expression Of High Affinity Methylaminoisobutryic Acid Transport In Hippocampal Neurons Inhibited By Riluzole And Novel Neuroprotective Aminothiazoles, Jeffrey D. Erickson, Thomas Kyllo, Heike Wulff

School of Medicine Faculty Publications

High affinity methylaminoisobutyric acid(MeAIB)/glutamine(Gln) transport activity regulated by neuronal firing occurs at the plasma membrane in mature rat hippocampal neuron-enriched cultures. Spontaneous Ca2+-regulated transport activity was similarly inhibited by riluzole, a benzothiazole anticonvulsant agent, and by novel naphthalenyl substituted aminothiazole derivatives such as SKA-378. Here, we report that spontaneous transport activity is stimulated by 4-aminopyridine (4-AP) and that phorbol-myristate acetate (PMA) increases high K+ stimulated transport activity that is inhibited by staurosporine. 4-AP-stimulated spontaneous and PMA-stimulated high K+-induced transport is not present at 7 days in vitro (DIV) and is maximal by DIV∼21. The relative affinity for MeAIB is similar …

Purification And Biochemical Characterization Of The Dna Binding Domain Of The Nitrogenase Transcriptional Activator Nifa From Gluconacetobacter Diazotrophicus, Heidi G. Standke, Lois Kim, Cedric P. Owens

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

NifA is a σ⁵⁴ activator that turns on bacterial nitrogen fixation under reducing conditions and when fixed cellular nitrogen levels are low. The redox sensing mechanism in NifA is poorly understood. In α- and β-proteobacteria, redox sensing involves two pairs of Cys residues within and immediately following the protein’s central AAA⁺ domain. In this work, we examine if an additional Cys pair that is part of a C(X)5 C motif and located immediately upstream of the DNA binding domain of NifA from the α-proteobacterium Gluconacetobacter diazotrophicus (Gd) is involved in redox sensing. We hypothesize that the …

Journal of Counselor Preparation and Supervision

The purpose of this study was to explore licensed counselors’ level of stigma toward individuals with substance use disorders (SUDs) and process/behavioral addictions (PBAs) and note any differences. A total of 138 licensed mental health counselors from one Midwestern state completed the SRTSS and the BRTSS to determine levels of stigma toward SUDs and PBAs, respectively. Participant scores from the SRTSS and BRTSS were normally distributed, and 15% to 32% of participants’ scores were reflective of stigma toward individuals with either SUDs or PBAs. A significant difference was not found between participants’ stigma toward individuals with SUDs or PBAs. Hypotheses …

Understanding An Inflammatory Pathway In Diabetic Retinopathy, Reanna R. Rodriguez

Research Symposium

Diabetic Retinopathy (DR) is the leading cause of blindness in the U.S. However, not much is known of its molecular pathway and how it attributes to increases in inflammatory response in the eye. One avenue we will investigate is the transforming growth factor beta (TGFB) signaling pathway and its effect of vascular endothelial growth factor (VEGF) secretion and cell viability. VEGF is the hallmark that exacerbates DR progression in prolonged diabetes. Some major concern that have arisen are the underlying effects of oxidants and antioxidants in elevating VEGF secretion in diabetes. In attempt to learn more, we evaluated how an …

Research Symposium

Los cánceres de pulmón, próstata e hígado se encuentran entre los más prevalentes en los hombres. El cáncer de mama, de cuello uterino y de tiroides se encuentran entre los más prevalentes en mujeres (OMS, 2019). El tratamiento del cáncer generalmente incluye quimioterapia y radioterapia; sin embargo, los medicamentos contra el cáncer disponibles tienen una selectividad baja y causan efectos adversos graves, como nefrotoxicidad, neurotoxicidad y mielosupresión (Matsuo et al., 2010). Por tanto, el diseño y desarrollo de compuestos como nuevos agentes anticancerígenos frente a los tipos de cáncer de mayor incidencia son de vital importancia en el campo de …

Characterization Of Epithelial Growth Factor Transcripts Identified In Crotalus Atrox Venom, Ivan Lopez, Ying Jia

Research Symposium

Epithelial Growth Factor (EGF) is the primary source in regeneration and stimulation of essential fibroblasts cells commonly found in epithelium. Studies have shown that snake venom components are becoming a growing factor in treating illnesses such as cancer, muscular dystrophy, chronic pain, blood pressure, blood clotting, etc. EGF in human cells contains a promising quaternary structure that can bind to snake venom metalloproteinases, proposing a means of activating biochemical responses through protein-protein interactions to regulate unwanted cellular functions. This supports promising research in achieving a greater understanding of regulation along cellular pathways through ligands, increasing the likelihood of targeting unwanted …

Mortaparibplus- A Novel Anticancer Small Molecule Abrogating Mortalin-P53 Interaction In Cancer Cells, Anissa N. Sari, Ahmed Elwakeel, Jaspreet K. Dhanjal, Vipul Kumar, Durai Sundar, Sunil C. Kaul, Renu Wadhwa

Research Symposium

Background. The cessation of tumor cell growth through cell cycle arrest and apoptosis is determined by p53, a tumor suppressor protein. However, the interaction between mortalin-p53 within cytoplasm/nucleus leads to the inactivation of p53 transcriptional activation function. The disruption of mortalin-p53 complex has been suggested as an approach for developing a potential anticancer drug.

Methods. A screening of a high-content chemical library was performed to determine a molecule with mortalin-p53-interaction disrupting characteristics. After four-rounds of visual assays, we discovered a triazole derivative (4-[(1E)-2-(2-phenylindol-3-yl)-1-azavinyl]-1,2,4-triazole, named Mortaparib^Plus) with a potential ability of disrupting mortalin-p53-complex. In this study, we recruited …
