Location Of The Fibronectin Binding Domain On The Fibronectin Attachment Protein Of Mycobacterium Avium Subsp. Paratuberculosis, Chrissy Rose Hattery

All Graduate Theses, Dissertations, and Other Capstone Projects

Mycobacterium avium paratuberculosis (MAP) is an acid-fast bacillus that causes a fatal granulomatous ileocolitis called Johne’s Disease that affects primarily ruminants. The impact of MAP infection in the US dairy industry is particularly severe, with up to 70.4% of the herds being infected and annual losses as high as $1.5 billion. MAP is capable of persisting for months in the livestock environment and surviving the pasteurization process. While several vaccines are available, none can prevent infection and treatment with antimycobacterial chemotherapy does not result in a cure. Management and control of MAP infection requires characterization of host-pathogen interaction at the …

Modifiable Health Disparities And Cardiovascular Disease Risk Factors In Latino Migrant Seasonal Farmworkers: A Meta-Analysis, Cindy Mendez

Kamal, Rasha A. Radwan, Basma A. Abdelrahman, Olfat A. Hammam, Mohey M. Elmazar, Aiman S. El-Khatib, Yasmeen M. Attia

Pharmacy

Experimental and clinical evidence implicate disrupted gut barrier integrity in provoking innate immune responses, specifically macrophages, towards the progression of non-alcoholic steatohepatitis (NASH). Peroxisome proliferator-activated receptors (PPARs), a subset of the nuclear receptor superfamily, act to fine-tune several metabolic and inflammatory processes implicated in NASH. As such, the current study was carried out to decipher the potential role of dual PPAR α/δ activation using elafibranor (ELA) on ileal macrophage polarization (MP) and its likely impact on the liver in a NASH setting. To achieve this aim, an in vitro NASH model using fat-laden HepG2 cells was first used to validate …

The Shortfalls Of Vulnerability Indexes For Public Health Decision-Making In The Face Of Emergent Crises: The Case Of Covid-19 Vaccine Uptake In Virginia, Lydia Cleveland Sa, Erika Frydenlund

VMASC Publications

Equitable and effective vaccine uptake is a key issue in addressing COVID-19. To achieve this, we must comprehensively characterize the context-specific socio-behavioral and structural determinants of vaccine uptake. However, to quickly focus public health interventions, state agencies and planners often rely on already existing indexes of "vulnerability." Many such "vulnerability indexes" exist and become benchmarks for targeting interventions in wide ranging scenarios, but they vary considerably in the factors and themes that they cover. Some are even uncritical of the use of the word "vulnerable," which should take on different meanings in different contexts. The objective of this study is …

Diabetic Retinopathy And The Role Of Vegf, Aishwarya Gatiganti, Laura Valdez, Andrew Tsin Ph.D.

School of Medicine Publications

Diabetic retinopathy (DR) is the leading cause of blindness in the working-age population. It works by disrupting the neural and vascular components in the retina and leads to loss of neural interaction/function, vascular permeability, and angiogenesis. It can be classified into two general stages: non-proliferative diabetic retinopathy (NPDR) and proliferative diabetic retinopathy (PDR). DR can also lead to vascular leakage and cause diabetic macular edema (DME), the most common cause of vision loss in DR (Duh, Sun et al. 2017). There are currently a wide range of therapies, but they are limited in their efficacy and side effects. None of …

Development Of Sensors For Bacteria And Wound Environment Monitoring, Pannawich Thirabowonkitphithan

Chulalongkorn University Theses and Dissertations (Chula ETD)

Diabetes mellitus (DM) is a leading cause of death and reduces life expectancy. Complications from diabetes have wreaked havoc not only on patients' quality of life, but also on the global burdens of public health and socioeconomic development. The most frequent complication among patients with diabetes mellitus is diabetic wounds, particularly diabetic foot ulcers because of the damage to sensory nerves and blood vessel issues brought on by elevated blood glucose levels. As a result, chronic wounds eventually develop and are prone to infection. In this study, several novel analytical devices for the detection of wound infections and the wound …

Publications and Research

Previous studies show increased sensitivity of older mice (28–29 months) compared with young adult mice (3 months, possessing a mature immune system) to radiation-induced GI lethality. Age-dependent lethality was associated with higher levels of apoptotic stem cells in small intestinal crypts that correlated with sphingomyelinase activity, a source of pro-apoptotic ceramide. The objective of this study is to determine whether the cycling crypt base columnar cells (CBCs) in aging animals are specifically more sensitive to radiation effects than the CBCs in young adult mice, and to identify factors that contribute to increased radiosensitivity. Mortality induced by subtotal body radiation was …

Distinctions Between Choroidal Neovascularization And Age Macular Degeneration In Ocular Disease Predictions Via Multi-Size Kernels Ξcho-Weighted Median Patterns, Alex Liew, Sos Agaian, Samir Benbelkacem

Publications and Research

Age-related macular degeneration is a visual disorder caused by abnormalities in a part of the eye’s retina and is a leading source of blindness. The correct detection, precise location, classification, and diagnosis of choroidal neovascularization (CNV) may be challenging if the lesion is small or if Optical Coherence Tomography (OCT) images are degraded by projection and motion. This paper aims to develop an automated quantification and classification system for CNV in neovascular age-related macular degeneration using OCT angiography images. OCT angiography is a non-invasive imaging tool that visualizes retinal and choroidal physiological and pathological vascularization. The presented system is based …

Characterizing Cellular Injury And Inflammation With Aldob-/-Mouse Model Of Mafld, Andy Rashid

All Master's Theses

Metabolic-associated fatty liver disease (MAFLD) affects 1 in 3 people in the US and is a healthcare burden on the order of billions of dollars. MAFLD is characterized by pathological lipid accumulation in the liver, excess production of triglycerides and cholesterol, and export of LDL particles that raise serum lipid levels. These metabolic perturbations can lead to the development of liver fibrosis, chronic inflammation, and insulin resistance. Diagnosing MAFLD prior to fibrosis is crucial for successful intervention and prevention of advanced liver disease and other metabolic complications. Fructose-1Phospahte (F1P) accumulation from fructose overconsumption can drive hepatic lipogenesis and MAFLD progression. …

Generation Of Chimeric Rhinoviruses Presenting Sars-Cov-2 Broadly Neutralizing Epitopes And Their Antigenicity Characterization, Danish Ansari

Biotechnology Theses

The global COVID pandemic is not yet fully under control as there were over 21 million new cases of SARS-CoV-2 infections and over 50,000 deaths globally as of January of 2022. A heavily mutated variant of concern, Omicron is responsible for most of these cases which demands an urgency for a new vaccine. NIH reports over 180 vaccine candidates that use various strategies currently in development. However, a recurring concern with these vaccines is that the continuous viral mutations decrease the efficacy of vaccines. Therefore, we proposed to construct a human rhinovirus (HRV) based chimeric virus containing highly conserved, broadly …

Lung-function impairment underlies chronic obstructive pulmonary disease (COPD) and predicts mortality. In the largest multi-ancestry genome-wide association meta-analysis of lung function to date, comprising 580,869 participants, we identified 1,020 independent association signals implicating 559 genes supported by ≥2 criteria from a systematic variant-to-gene mapping framework. These genes were enriched in 29 pathways. Individual variants showed heterogeneity across ancestries, age and smoking groups, and collectively as a genetic risk score showed strong association with COPD across ancestry groups. We undertook phenome-wide association studies for selected associated variants as well as trait and pathway-specific genetic risk scores to infer possible consequences of …

The aim of this study is to examine the association between prevalence of schistosomiasis and livestock cattle index in Nigeria. The study's data came from three sources: the demographic and health survey (DHS), the malaria indicators survey (MIS), and the expanded special project for the eradication of neglected tropical diseases (ESPEN). Analysis of variance, correlation, and logistic regression were used to evaluate the mean difference in schistosomiasis prevalence across geopolitical zones, the relationship between schistosomiasis prevalence and livestock cattle, …

Estimating The Distribution Of Oryzomys Palustris, A Potential Key Host In Expanding Rickettsial Tick-Borne Disease Risk, Catherine A. Lippi, Samuel Canfield, Christina Espada, Holly D. Gaff, Sadie J. Ryan

Biological Sciences Faculty Publications

Increasingly, geographic approaches to assessing the risk of tick-borne diseases are being used to inform public health decision-making and surveillance efforts. The distributions of key tick species of medical importance are often modeled as a function of environmental factors, using niche modeling approaches to capture habitat suitability. However, this is often disconnected from the potential distribution of key host species, which may play an important role in the actual transmission cycle and risk potential in expanding tick-borne disease risk. Using species distribution modeling, we explore the potential geographic range of Oryzomys palustris, the marsh rice rat, which has been …

Considerations In The Management Of Juvenile Absence Epilepsy In Pregnancy And In Females Of Childbearing Age, Casey Brew

Capstone Showcase

JAE is an epilepsy syndrome that typically requires lifelong AED treatment, and valproic acid or lamotrigine is considered first line to manage the spectrum of associated seizures. In females with JAE who become pregnant, there exist risks both from having uncontrolled seizures and from taking AEDs during the pregnancy. Valproic acid carries the highest risks to the fetus but is the most effective in controlling the seizure types seen with JAE. Folic acid supplementation has shown to mitigate some but not all of the fetal risks from valproic acid. Limited guidance from professional organizations exists for management of females of …

Non-Pharmaceutical Symptom Management In Patients With Pcos, Allison Stern

Capstone Showcase

Polycystic Ovarian Syndrome (PCOS) is a relatively common diagnosis among biological females. There are many variations of presentations among patients with PCOS that require an individualized and tailored treatment plan for symptom management. Although there are pharmaceutical medications that can be used for PCOS symptoms, some patients’ symptoms might not be fully managed, or they might prefer to focus on non-pharmaceutical options for their symptoms instead. Therefore, it is important for clinicians to be familiar with alternatives to the mainstay of pharmaceutical treatment.

Acute Otitis Media: Management And Recurrence In The Pediatric Population, Sydney Klaiman

Autoimmune Thyroiditis (AIT) is a prevalent autoimmune disease affecting approximately 2% of the population. Characterized by the gradual loss of thyroid function through an autoimmune attack on the thyroid gland, the disease manifests symptoms that negatively affect one’s quality of life. The mechanisms behind the disease’s pathophysiology are not fully understood; however, researchers are examining the involvement of the NLRP3 inflammasome in the disease. This thesis will address the question of whether Vitamin D can act as an inhibitor of the NLRP3 inflammasome and attenuate the progression of AIT in mouse model. Current investigations explore the effects of NLRP3 inhibition …

High Energy Blue Light Induces Oxidative Stress And Retinal Cell Apoptosis, Jessica Malinsky

Capstone Showcase

Blue light (BL) is a high energy, short wavelength spanning 400 to 500 nm. Found in technological and environmental forms, BL has been shown to induce photochemical damage of the retina by reactive oxygen species (ROS) production. Excess ROS leads to oxidative stress, which disrupts retinal mitochondrial structure and function. As mitochondria amply occupy photoreceptors, they also contribute to oxidative stress due to their selectively significant absorption of BL at 400 to 500 nm. ROS generation that induces oxidative stress subsequently promotes retinal mitochondrial apoptosis. BL filtering and preventative mechanisms have been suggested to improve or repair BL-induced retinal damage, …
