Q-Griffithsin Interactions And Utility For The Prevention And Treatment Of Mucosal Infections., Henry Nabeta
Q-Griffithsin Interactions And Utility For The Prevention And Treatment Of Mucosal Infections., Henry Nabeta
Electronic Theses and Dissertations
Griffithsin (GRFT) is a carbohydrate binding agent (lectin) that was originally identified in the red alga Griffithsia sp. Q-Griffithsin (Q-GRFT) is an oxidation stable analog of GRFT. GRFT has demonstrated inhibitory activity against HIV-1, Coronaviruses, Hepatitis C, influenza and Ebola viruses. The broad-spectrum activity suggests the potential utility of this lectin in a wide range of viral infections. However, the lectin’s activity in mucosal infections has not been extensively studied. Using in vitro, ex vivo and in vivo assays, we have demonstrated that Q-GRFT maintains the ability to bind glycosylated ligands following incubation in murine, macaque and human rectal …

SARS-CoV-2, the virus that causes COVID-19 consists of several enzymes with essential functions within its proteome. Here, we focused on repurposing approved and investigational drugs/compounds. We targeted seven proteins with enzymatic activities known to be essential at different stages of the viral cycle including PLpro, 3CLpro, RdRP, Helicase, ExoN, NendoU, and 2′-O-MT. For virtual screening, energy minimization of a crystal structure of the modeled protein was carried out using the Protein Preparation Wizard (Schrodinger LLC 2020-1). Following active site selection based on data mining and COACH predictions, we performed a high-throughput virtual screen of drugs and investigational molecules (n = …

Obesity prevails worldwide to an increasing effect. For example, up to 42% of American adults are considered obese. Obese individuals are prone to a variety of complications of metabolic disorders including diabetes mellitus, hypertension, cardiovascular disease, and chronic kidney disease. Recent meta-analyses of clinical studies in patient cohorts in the ongoing coronavirus-disease 2019 (COVID-19) pandemic indicate that the presence of obesity and relevant disorders is linked to a more severe prognosis of COVID-19. Given the significance of obesity in COVID-19 progression, we provide a review of host metabolic and immune responses in the immunometabolic dysregulation exaggerated by obesity and the …

Coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), resulted in an unprecedented global crisis. Although primarily a respiratory illness, dysregulated immune responses may lead to multi-organ dysfunction. Prior data showed that the resident microbial communities of gastrointestinal and respiratory tracts act as modulators of local and systemic inflammatory activity (the gut-lung axis). Evolving evidence now signals an alteration in the gut microbiome, brought upon either by cytokines from the infected respiratory tract or from direct infection of the gut, or both. Dysbiosis leads to a "leaky gut". The intestinal permeability then allows access to …

COVID-19 vaccine allocation efforts have posed challenges and offered opportunities to alleviate the ongoing pandemic. Nations have employed varying approaches for COVID-19 vaccine distribution; in particular, Mongolia and India have differed in approaches to vaccine allocation efforts. As of June 2021, Mongolia has vaccinated more than 60% of its population, whereas India has only vaccinated about 7.5%. This disparity highlights the need for the present study, which utilizes a mixed-method approach to examine the two countries' vaccine distribution strategies and COVID-19 containment policies from January to July 2021. The study has three major components: 1) policy analysis to highlight core …

Medical Populism And Covid-19 Testing, Kristin Hedges, Gideon Lasco
Medical Populism And Covid-19 Testing, Kristin Hedges, Gideon Lasco
Development Studies Faculty Publications
This paper uses the lens of medical populism to analyze the impact of biocommunicability on COVID-19 testing through a case study approach. The political efficacy of testing is traced through two mini-case studies: the Philippines and the United States. The case studies follow the approach of populism scholars in drawing from various sources that ‘render the populist style visible’ from the tweets and press releases of government officials to media reportage. Using the framework of medical populism, the case studies pay attention to the ways in which coronavirus testing figured in (1) simplification of the pandemic; (2) spectacularization of the …

COVID-19 has plagued countries worldwide due to its infectious nature. Social distancing and the use of personal protective equipment (PPE) are two main strategies employed to prevent its spread. A SIR model with a time-dependent transmission rate is implemented to examine the effect of social distancing and PPE use in hospitals. These strategies’ effect on the size and timing of the peak number of infectious individuals are examined as well as the total number of individuals infected by the epidemic. The effect on the epidemic of when social distancing is relaxed is also examined. Overall, social distancing was shown to …

Disparities In Sars-Cov-2 Positivity Rates: Associations With Race And Ethnicity, Harvey W Kaufman, Justin K Niles, David B. Nash
College of Population Health Faculty Papers
Numerous reports indicate that African Americans and Latinos are being affected disproportionately by coronavirus disease 2019 (COVID-19). Positivity rates have not been analyzed on scale because only 4 states report race/ethnicity as part of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing. Previous studies also have had little ability to control for many known risk factors to better identify the effects of COVID-19 on racial and ethnic communities. Using test results from a large national reference laboratory database that included patients from all 50 states and the District of Columbia, this study compared positivity rates for SARS-CoV-2 nucleic acid amplification …

The current novel coronavirus disease (COVID-19) has spread globally within a matter of months. The virus establishes a success in balancing its deadliness and contagiousness, and causes substantial differences in susceptibility and disease progression in people of different ages, genders and pre-existing comorbidities. These host factors are subjected to epigenetic regulation; therefore, relevant analyses on some key genes underlying COVID-19 pathogenesis were performed to longitudinally decipher their epigenetic correlation to COVID-19 susceptibility. The genes of host angiotensin-converting enzyme 2 (ACE2, as the major virus receptor) and interleukin (IL)-6 (a key immuno-pathological factor triggering cytokine storm) were shown to evince active …

Computing For Numeracy: How Safe Is Your Covid-19 Social Bubble?, Charles Connor
Numeracy
The COVID-19 pandemic has led many people to form social bubbles. These social bubbles are small groups of people who interact with one another but restrict interactions with the outside world. The assumption in forming social bubbles is that risk of infection and severe outcomes, like hospitalization, are reduced. How effective are social bubbles? A Bayesian event tree is developed to calculate the probabilities of specific outcomes, like hospitalization, using example rates of infection in the greater community and example prior functions describing the effectiveness of isolation by members of the social bubble. The probabilities are solved for two contrasting …

Developing A Self-Sanitizing Mask To Combat The Spread Of Infectious Disease, Matthew Crawford
Developing A Self-Sanitizing Mask To Combat The Spread Of Infectious Disease, Matthew Crawford
Honors Undergraduate Theses
Masks have become an important part of everyday life, protecting both the wearer and individuals nearby from the spread of infectious diseases, most notably severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the coronavirus that causes coronavirus disease 2019 (COVID-19). However, these masks are easily contaminated, whether through continued use or by the wearer touching the mask fabric with contaminated hands, therefore reducing the efficacy and exposing the user to these contagions. When the mask becomes contaminated, it can be discarded, which produces large amounts of waste that will end up in a landfill, or it can be washed, which is …

Coronavirus disease 2019 (COVID-19) has poorer clinical outcomes in males than in females, and immune responses underlie these sex-related differences. Because immune responses are, in part, regulated by metabolites, we examined the serum metabolomes of COVID-19 patients. In male patients, kynurenic acid (KA) and a high KA–to–kynurenine (K) ratio (KA:K) positively correlated with age and with inflammatory cytokines and chemokines and negatively correlated with T cell responses. Males that clinically deteriorated had a higher KA:K than those that stabilized. KA inhibits glutamate release, and glutamate abundance was lower in patients that clinically deteriorated and correlated with immune responses. Analysis of …

Are Covid-19 Vaccine Boosters Needed? The Science Behind Boosters, Rachel M. Burckhardt, John J. Dennehy, Leo L. M. Poon, Linda J. Saif, Lynn W. Enquist
Publications and Research
Waning vaccine-induced immunity coupled with the emergence of SARS-CoV-2 variants has led to increases in breakthrough infections, prompting consideration for vaccine booster doses. Boosters have been reported to be safe and increase SARS-CoV-2-specific neutralizing antibody levels, but how these doses impact the trajectory of the global pandemic and herd immunity is unknown. Information on immunology, epidemiology and equitable vaccine distribution should be considered when deciding the timing and eligibility for COVID-19 vaccine boosters.

Covid-19 Employee Health Checks, Remote Work, And Disability Law, Elizabeth Pendo
All Faculty Scholarship
The Americans with Disabilities Act (ADA) prohibits discrimination against people with disabilities, about 61 million individuals in the U.S. The law’s protections in the workplace are especially important during COVID-19, which has worsened pre-existing disparities experienced by people with disabilities. The ADA also applies to new strategies to reduce the risk of COVID-19 infection in the workplace. This Chapter will focus on two strategies that impact individuals with and without disabilities – employee health screening, testing and vaccination policies, and new or expanded remote work programs.
