Prevalence Of Snake Fungal Disease Caused By Ophidiomyces Ophiodiicola In East Texas, Alan Lizarraga

Biology Theses

Fungal pathogens and resultant disease are credited with the decline of many species across all branches of the tree of life. Fungal diseases such as Snake Fungal Disease (SFD), primarily caused by the fungus Ophidiomyces ophiodiicola (Oo), have been strongly associated with the cause of the decrease/disappearance of many snake populations in North America. To date SFD in the wild has been described as far southwest as central Louisiana. Due to similar conditions and the proximity of East Texas to central Louisiana, a survey of local snake populations provided crucial information about the spread and presence of this emerging pathogen. …

Immune Activation Induces Telomeric Dna Damage, Reduces Memory Precursors, And Promotes Short-Lived Effector T Cell Differentiation In Chronic Hcv Infection, Lam Nguyen

Electronic Theses and Dissertations

Chronic hepatitis C virus (HCV) infection exhibits persistent high viral load, inducing T cells differentiation and dysfunction in chronically infected individuals. Recent longitude studies in both HCV specific- and bulk T cells reveal that chronic immune stimulation is the driving force for the impaired T cell functions, however, the underlying mechanisms remain elusive. Here, we show that peripheral CD4⁺ T cells from chronically HCV-infected patients exhibit lymphopenia with the reduction of naïve population and expansion of effector memory T cells. CD4⁺ T cells from HCV patient also display elevated activation markers. including HLA-DR, GLUT1, Granzyme B, and short-lived …

A correlational analysis of the biochemical parameters of these individuals with HBV and HCV infection was carried out and the results indicated a positive correlation of HBV with Alkaline Phosphatase (ALP), HCV with Total Bilirubin (TBil) and both …

Coronavirus Food Assistance Program For Livestock Producers, Bradley Lubben

Extension Farm and Ranch Management News

United States Congress and the President have approved multiple phases of COVID-19 assistance to date including the $2.3 trillion CARES (Coronavirus Aid, Relief, and Economic Security) Act passed in March that provides financial support for agricultural producers as a small part of the overall relief.

While agricultural producers and agribusinesses are eligible for two programs administered through the Small Business Administration, including the Paycheck Protection Program (PPP) and Economic Injury Disaster Loans (EIDLs), the primary support for agriculture is coming from USDA through the Coronavirus Food Assistance Program (CFAP). The CARES Act provided $9.5 billion directly to the Secretary of …

Design And Synthesis Of Novel Analogs As Potential Antitubercular Agents, Peggy Mccluggage

Honors Theses

Tuberculosis (TB) is an infectious, airborne disease which primarily infects the lungs. One-third of the world’s population is currently estimated to be infected with Mycobacterium tuberculosis (Mtb), the causative agent for TB [1]. Current treatment for this disease requires at least six months of taking multiple antibiotics with undesirable side effects [2]. Difficulty in complying to this regimen as well as the prevalence of HIV/AIDS has led to antimicrobial resistance seen in Mtb. In order to combat the Multi-Drug Resistant and Extensively-Drug Resistant strains of the disease-causing bacteria, preventative care and novel antibiotics are urgently needed [3]. The purpose for …

Has Covid-19 Impacted Price-Weight Relationships And Value Of Gain?, Elliott James Dennis

Extension Farm and Ranch Management News

First paragraph:

In the beginning of COVID-19, much of the attention was focused on managing the redirection of meat product from food service to retail stores. This past month has keenly focused on packing plant closures due to COVID-19 cases among workers and how to manage the supply of fat cattle already ready for slaughter. Fat cattle available for slaughter either cannot get bids or bids are significantly below breakeven prices leaving feedlots with decisions to be made about marketing and placements. The April 2020 Cattle on Feed report (https://usda.library.cornell.edu/concern/publications/m326m174z) revealed March placement decisions. Placements were down about …

Live Cattle Basis Due To Covid-19: Deviations And Convergence, Elliott James Dennis

Extension Farm and Ranch Management News

A Fundamental Review on Basis

Basis is defined as the cash minus futures. Cash market reflects today's supply conditions and price. Futures market reflects upcoming supply and demand conditions. If it is anticipated that there will be a period of increasing supplies, futures prices will decline to reflect that information. Likewise, periods of time with expected decreasing supplies, future prices are expected to increase.

Since cash and futures prices can move simultaneously, basis will fluctuate through time. In periods where basis becomes more positive (i.e. basis is said to be strengthening/narrowing) it implies that cash prices are increasing more relative …

Pre Covid-19 Market Conditions Persist & The Stocker Industry Can Dampen The Damage, Elliott James Dennis

Extension Farm and Ranch Management News

First paragraph:

The effects of COVID-19 on the livestock market are well known and felt. Some effects include depressed futures and cash prices, unusual basis patterns, decreased packer bids and sale barn volume, packing plant closures, consumer hording of meat products, and shifting food service products for retail consumption. All these effects occurred as market participants grappled with everchanging government and industry policy which reduced consumer demand and resulted in bottlenecks and increasing supply gluts upstream. Simultaneously reducing demand and increasing supply always cause prices to plummet, and in the case of COVID-19 very rapidly. Some segments of the market …

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 …

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 …

Virulence Of Drosophila C Virus Increased After A Host Shift And Serial Passage In Drosophila Hosts, Katie A. Johnson

EWU Masters Thesis Collection

The outcomes of novel host-pathogen interactions are unpredictable but can result in epidemics or pandemics. Exploring the initial encounter between a pathogen and a novel host species can elucidate why some pathogens successfully infect and adapt on a novel host when others fail. Much of our understanding of host virulence after host shifts was developed using serial passage experiments (SPEs) in bacteria. Three accepted SPE generalities have emerged: virulence increases on the novel host, the evolved pathogen will become less able to infect its native host, and the pathogen experiences convergent evolution. This study tests the first two generalities using …

Elephants And Pandemics, Adrian Treves

Animal Sentience

Baker & Winkler’s critique of Asian elephant tourism and conservation in Thailand has convinced me that this was “an industry with too many victims.” Yet I fear that B&W’s proposed remedy of returning to past elephant husbandry by Karen hill-peoples has little likelihood of improving the lives of the elephants for long. Who can predict whether the Karen will live up to this hope? B&W advocate for the Karen, but not for “an abolitionist stance on elephant-human relationships.” In my view, whether we discuss elephants or the wild mammals that carry SARS-CoV-2, abolition of many human uses of animals is …

Lps, A Tlr-4 Agonist And Viper A Tlr-4 Inhibitor Upregulate Phagocytosis Of Zymosan In Bv2 Cells, Sherouk Alzeory

Dissertations and Theses

Microglia cells are the first line of innate immunity defense in the central nervous system (CNS). They play a critical role in maintaining CNS homeostasis by having an active but yet balanced phagocytic activity. However, in various CNS related diseases, microglia cells have been shown to malfunction. In Alzheimer's Disease (AD), hyperactive microglia with impaired phagocytic activity is the main hallmark of this disease, along with the accumulation of amyloid-beta aggregates. Additionally, emerging new studies have suggested a fungal infection etiology to AD, specifically in relation to Candida albicans (C.albicans). Thus, understanding the mechanism of fungal clearance in the …

Identification Of Imiquimod As A Potential Combination For Anti-Cd47 Antibodies In Cancer Therapy, Nicole Brittaney Pang

Scripps Senior Theses

The avenues of targeted immunotherapy offers a promise of less toxic treatment options for those battling different forms of cancer. Specifically, the process of hijacking a patient’s own immune system to fight cancer from within versus using external treatments like chemotherapy which is extremely damaging to the patient. One such avenue includes the usage of monoclonal antibodies as an effective modality for immunotherapy. Cluster of Differentiation 47 (CD47), also known as the ‘don’t eat me signal’, aids in cell proliferation and evasion of phagocytosis and has been found to be a target for stopping tumorigenesis. Previous research has been successful …

Immunotherapy: Therapy Vs. Enhancement, Mariah Daly

Honors Program Theses

The battle against cancer is a long-standing struggle that has resulted in new information and the development of novel medical technologies. Current research aims to figure out a way to reprogram cells and bodily mechanisms to eliminate those cells that are cancerous without destroying healthy cells in the process. Methods which use the body’s own mechanisms, such as immunotherapy, have shown and continue to show potential for specifically targeting cancer cells. Adoptive T cell therapy is one form of immunotherapy that has gained significant attention and focus in the field. Therapies improve conditions up to the normal state of being, …

Why The Government Shouldn't Pay People To Get Vaccinated Against Covid-19, Ana Santos Rutschman

All Faculty Scholarship

As several pharmaceutical companies approach the Food and Drug Administration (FDA) seeking authorization to bring COVID-19 vaccines to market, concerns about vaccine mistrust cloud the prospects of imminent vaccination efforts across the globe. These concerns have prompted some commentators to suggest that governments may nudge vaccine uptake by paying people to get vaccinated against COVID-19. This post argues that, even if potentially viable, this idea is undesirable against the backdrop of a pandemic marked by the intertwined phenomena of health misinformation and mistrust in public health authorities. Even beyond the context of COVID-19, paying for vaccination is likely to remain …
