Influenza Vaccination Coverage In Pediatric Patients With Inflammatory Bowel Disease, Kelly Brown

Senior Theses

Background: Children with chronic health conditions, including inflammatory bowel disease (IBD), are at especially high risk for influenza infection and complications. The Crohn’s & Colitis Foundation and American College of Gastroenterology recommend that IBD patients should receive annual influenza vaccination. The aims of this study were to evaluate influenza vaccination coverage over time and identify predictors of flu vaccination in pediatric IBD and non-IBD patients.

Methods: We utilized longitudinal data (2000 to 2016) from South Carolina Medicaid to conduct a matched cohort study. The primary exposure of interest was IBD diagnosis based upon ICD-9/10 diagnosis codes. Children with IBD were …

Understanding The Role Of Cereblon In Hematopoiesis Through Structural And Functional Analyses, Afua Adutwumwa Akuffo

USF Tampa Graduate Theses and Dissertations

The discovery and implementation of immunomodulatory drugs (IMiD®s) has revolutionized the treatment of many hematological malignancies due to the plethora of IMiD®-induced clinical responses that include anti-angiogenesis, anti-inflammation, and anti-tumor effects, as well as enhanced erythropoiesis, immune modulation and improved metabolism. More ground-breaking was the identification of cereblon as the target of IMiD®s. Upon binding to thalidomide and other immunomodulatory drugs, the E3 ligase substrate receptor cereblon (CRBN) promotes proteosomal destruction of neo-substrates by engaging the DDB1-CUL4A-Roc1-RBX1 E3-ubiquitin ligase in human cells but not in mouse cells suggesting that sequence variations in CRBN may cause its inactivation. Therapeutically, CRBN engagers …

Parásitos Gastrointestinales De Tierra Del Fuego, Argentina, Sarah Martínez

Independent Study Project (ISP) Collection

Este trabajo intentó encontrar helmintos comunes, especialmente compartidos, en cuatro carnívoros patagónicos del sur con distribuciones geográficas superpuestas y dos carnívoros patagónicos del norte, y esbozar el análisis fecal y los métodos de identificación morfológica para futuros investigadores. El estudiante encontró solo un parásito helminto compartido entre cualquier otra especie y la nutria nativa del sur del río, a pesar de una superposición en el hábitat con el visón americano invasivo, pero esto puede deberse a un bajo recuento de estudios regionales previos de helmintos en cualquiera de las especies. Se encontraron múltiples parásitos en las cuatro especies hospederas de …

Role Of Ixodes Scapularis Sphingomyelinase-Like Protein (Issmase) In Tick Pathogen Interactions, Pravesh Regmi

Biological Sciences Theses & Dissertations

Arthropod-borne diseases are one of the major concerns throughout the world. Ixodes scapularis (hard tick) is one of the major vectors that is involved in arthropod-borne disease transmission. Langat virus (LGTV) is a model pathogen that is very similar to other medically important flaviviruses such as Tick-Borne Encephalitis virus (TBEV) and Powassan virus (POWV). Sphingomyelinase-like protein (IsSMase, a Sphingomyelinase D or SMase D, a venomous protein ortholog of spiders) is an enzyme present in ticks that helps to catalyze the hydrolysis of the sphingomyelin (cell membrane lipid) into phosphocholine and ceramide. The objective of our study is to delineate the …

Introduction

On 30 January 2020, the World Health Organization (WHO) declared a Global Health Emergency of international concern attendant to the emergence and spread of SARS-CoV-2, nearly two months after the first reported emergence of human cases in Wuhan, China. In the subsequent two months, global, national and local health personnel and infrastructures have been overwhelmed, leading to suffering and death for infected people, and the threat of socio-economic instability and potential collapse for humanity as a whole. This shows that our current and traditional mode of coping, anchored in responses after the fact, is not capable of dealing with …

Investigating Mechanisms Of Immune Suppression Secondary To An Inflammatory Microenvironment, Wendy Michelle Kandell

USF Tampa Graduate Theses and Dissertations

The immune system plays a dynamic role in cancer progression. The theory of immunoediting suggests that the relationship between the tumor cell and the immune cell is one that is in flux: initially highly active and responsive to tumor antigen to one that has escaped immune responsiveness. Once the tumor has formed and effectively “escaped”, there are multiple mechanisms that work against a conventional immune response. The tumor cell clones that have escaped the elimination phase are those that are less immunogenic. These clones downregulate MHC, have increased apoptosis through DAMP-driven mechanisms, and suppressive cell phenotypes are driven through cytokine-driven …

Perplexing Role Of P-Glycoprotein In Tumor Microenvironment, Kianna Robinson, Venkataswarup Tiriveedhi

Biology Faculty Research

Development of multidrug resistance (MDR) still remains a major obstacle to the long-term success of cancer therapy. P-glycoprotein (P-gp) is a well-identified membrane transporter with capability to efflux drug molecules out of the cancer cell leading to reduced efficiency of chemotherapy. Cancer cells upregulate P-gp expression as an adaptive response to evade chemotherapy mediated cell death. While several P-gp inhibitors have been discovered by in silico and pre-clinical studies, very few have successfully passed all phases of the clinical trials. Studies show that application of P-gp inhibitors in cancer therapy regimen following development of MDR achieved limited beneficial outcomes. While, …

Defining Parental Resistance: The Social Determinants Of Measles Vaccine Hesitancy, Michael C. Goates, M. Lelinneth B. Novilla, Mallory Showalter, L. Kirsten Novilla, Russell Doria, Michael Dang, Tyler Leffler, Katelyn Aldridge

Faculty Publications

The increase in vaccine-preventable disease (VPD) outbreaks has caused great alarm to the public health community. In recent years, VPD outbreaks have occurred across the globe in both developed and developing countries. Particularly troubling has been the resurgence of diseases formerly eradicated through years of concerted vaccination and other public health campaigns. Higher vaccination exemption rates have been implicated in the resurgence of VPDs. This is particularly evident in the United States where measles outbreaks reached 1,250 individual cases in 2019 alone, the most confirmed cases since 1992. Central to the discussion about measles resurgence is a better understanding of …

Cysteine Dioxygenase Enzyme Activity And Gene Expression In The Dimorphic Pathogenic Fungus Histoplasma Capsulatum Is In Both The Mold And Yeast Morphotypes And Exhibits Substantial Strain Variation, Melissa Adams, Glen Shearer

Faculty Publications

In the dimorphism (mold/yeast) Histoplasma capsulatum (Hc) literature are reports that yeast (the so-called pathogenic form) uniquely expresses a cysteine dioxygenase (CDO, approx. 10,500 dal) activity which the mold morphotype (the so-called saprophytic soil form) does not express (C.F., Kumar et al., Biochem 22, 762, 1983). This yeast-specific CDO activity is postulated to play a critical role in the mold-to-yeast shift. A number of years ago, our lab isolated the gene encoding the Hc cysteine dioxygenase (CDO1, Genbank accession AY804144) and noted significant expression in the mold morphotype of several Histoplasma strains and also determined that the predicted protein would …

Checklist Of The Hard Tick (Acari: Ixodidae) Fauna Of Hungary With Emphasis On Host‑Associations And The Emergence Of Rhipicephalus Sanguineus, Sándor Hornok, Dávid Kováts, Gábor Horváth, Jenő Kontschán, Róbert Farkas

Harold W. Manter Laboratory of Parasitology: Library Materials

Hungary is situated in the southern part of Central Europe, next to the northern boundary of the Mediterranean region. This geographical position may allow the northward expansion of Mediterranean ixodid tick species into Hungary, particularly in the era of warming climate. During the past 14 years numerous surveys have been published on the species and activity of hard ticks occurring in the country. However, it was 60 years ago that the last comprehensive review of ixodid ticks of Hungary was published, and only in Hungarian language. The purpose of the present checklist is to provide a comprehensive and complete overview …

Mutational Analysis And Domain Characterization Of The Apolipoprotein L-1 Ion Channel, Charles M. Schaub

Dissertations, Theses, and Capstone Projects

The human innate immunity factor Apolipoprotein L-1 (APOL1) protects against Trypanosoma brucei brucei infection. Recent studies have shown recombinant APOL1 (rAPOL1) inserts into planar lipid bilayers at an acidic pH 5.6 and forms a cation-selective channel, which opens upon subsequent neutralization, pH 7.2. This corresponds with the pH changes APOL1 would encounter during endosome recycling, suggesting that APOL1 forms a pH-gated ion channel in the plasma membrane of the parasite, leading to uncontrolled ion flux and osmotic imbalance. However, structural and domain characteristics of the APOL1 channel are poorly understood, despite potential similarities to diphtheria and colicin toxins. Utilizing E. …

Phylogenetic Afficity Of Genolopa (Digenea: Monorchiidae) With Descriptions Of Two New Species, Apryle J. Panyi, Stephen S. Curran, Robin M. Overstreet

Faculty Publications

The validity of Genolopa Linton, 1910 has been controversial because the observation of presently recognized critical diagnostic morphological features (spines in the genital atrium and a bipartite, anteriorly spined terminal organ) were omitted from the original diagnosis, and these features were not universally appreciated as important diagnostic features until 2008. Modern taxonomists have been further challenged by inappropriate fixation techniques that have resulted in various interpretations of morphological features. Consequently, named species in the genus have fluctuated among other monorchiid genera depending on various interpretations by taxonomists, and a modern consensus on classifying these species is lacking. This study …

Predicting The Potential Distribution Of Amblyomma Americanum (Acari: Ixodidae) Infestation In New Zealand, Using Maximum Entropy‑Based Ecological Niche Modelling, R. K. Raghavan, A. C.G. Heath, K. E. Lawrence, R. R. Ganta, A. T. Peterson, W. E. Pomroy

Harold W. Manter Laboratory of Parasitology: Library Materials

Although currently exotic to New Zealand, the potential geographic distribution of Amblyomma americanum (L.), the lone star tick, was modelled using maximum entropy (Max- Ent). The MaxEnt model was calibrated across the native range of A. americanum in North America using present-day climatic conditions and occurrence data from museum collections. The resulting model was then projected onto New Zealand using both present-day and future climates modelled under two greenhouse gas emission scenarios, representative concentration pathways (RCP) 4.5 (low) and RCP 8.5 (high). Three sets of WorldClim bioclimatic variables were chosen using the jackknife method and tested in MaxEnt using different …
