A Monte Carlo Simulation Of A Protein (Cove) In A Matrix Of Random Barriers, R. B. Pandey

Faculty Publications

Monte Carlo simulations are performed to study structure and dynamics of a protein CoVE in random media generated by a random distribution of barriers at concentration c with a coarse-grained model in its native (low temperature) and denatured (high temperature) phase. The stochastic dynamics of the protein is diffusive in denature phase at low c, it slows down on increasing c and stops moving beyond a threshold (c_th ≈ 0.10). In native phase, the protein moves extremely slow at low c but speeds up on further increasing c in a characteristic range (c =0.10–0.20) before …

The inclusion of infants in the SARS-CoV-2 vaccine rollout is important to prevent severe complications of pediatric SARS-CoV-2 infections and to limit transmission and could possibly be implemented via the global pediatric vaccine schedule. However, age-dependent differences in immune function require careful evaluation of novel vaccines in the pediatric population. Toward this goal, we assessed the safety and immunogenicity of two SARSCoV- 2 vaccines. Two groups of eight infant rhesus macaques (RMs) were immunized intramuscularly at weeks 0 and 4 with stabilized prefusion SARS-CoV-2 S-2P spike (S) protein encoded by mRNA encapsulated in lipid nanoparticles (mRNA-LNP) or the purified S …

Contagion And Crisis: Narrating Egypt’S 1947 Epidemic In Literature And Film, Nada Maurice Ibrahim

Theses and Dissertations

In 1947, cholera struck Egypt causing around 10,277 deaths from a total of 20,804 cases within a few months. What does the cholera outbreak reveal about Egyptian society at the time? How did different writers and filmmakers respond to it? Although several studies have tackled epidemics and the emergence of medical and public health practice in Egypt from an historical perspective, virtually none to date have seriously examined Egypt’s 1947 cholera epidemic from a literary standpoint. This thesis, by analysing the epidemic through works produced about or during the time of the epidemic, offers a deeper insight into the event …

Formulation Of Coffee Extract As Polymeric Nanoparticles And Studying Their Potential Biological Activities, Nouran Sharaf

Theses and Dissertations

Coffee extract was prepared and optimized (by solvent extraction) and subsequently entrapped into PLGA nanoparticles using single emulsion-solvent evaporation method (using Design Expert software).

Deacylated Trna Accumulation Is A Trigger For Bacterial Antibiotic Persistence Independent Of The Stringent Response, Whitney N. Wood, Kyle Mohler, Jesse Rinehart, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Bacterial antibiotic persistence occurs when bacteria are treated with an antibiotic and the majority of the population rapidly dies off, but a small subpopulation enters into a dormant, persistent state and evades death. Diverse pathways leading to nucleoside triphosphate (NTP) depletion and restricted translation have been implicated in persistence, suggesting alternative redundant routes may exist to initiate persister formation. To investigate the molecular mechanism of one such pathway, functional variants of an essential component of translation (phenylalanyltRNA synthetase [PheRS]) were used to study the effects of quality control on antibiotic persistence. Upon amino acid limitation, elevated PheRS quality control led …

Coagulopathy In Covid-19: A Review, Shannon Ginty

International Undergraduate Journal of Health Sciences

Recent data has demonstrated that the pathophysiology of severe COVID-19 infection is associated with a significant pulmonary coagulopathy. Thrombotic complications have been reported in approximately 35-45% of patients with severe COVID-19. Entry of SARS-CoV-2 into the host cells leads to dysregulation in inflammatory signalling pathways, disrupting the normal coagulation mechanism. The hypercoagulability with abnormal clot formation is attributed to the inappropriately elevated immune response, culminating in a ‘cytokine storm’ with high levels of pro-inflammatory cytokines and subsequent thrombosis. The coagulopathy in COVID-19 affects many coagulation parameters such as D-dimer levels, fibrinogen levels, platelet count and prothrombin time. Coagulation parameters must …

Coxsackievirus B3 (CVB3), is commonly implicated in myocarditis, which can lead to dilated cardiomyopathy, in addition to causing acute pancreatitis and meningitis. Yet, no vaccines are currently available to prevent this infection. Here, we describe the derivation of a live attenuated vaccine virus, termed mutant (Mt) 10, encoding a single amino acid substitution H790A within the viral protein 1, that prevents CVB3 infection in mice and protects from both myocarditis and pancreatitis in challenge studies. We noted that animals vaccinated with Mt 10 developed virus neutralizing antibodies, predominantly containing IgG2a and IgG2b, and to a lesser extent IgG3 and IgG1. …

Adapting An Agent-Based Model Of Infectious Disease Spread In An Irish County To Covid-19, Elizabeth Hunter, John D. Kelleher

Articles

The dynamics that lead to the spread of an infectious disease through a population can be characterized as a complex system. One way to model such a system, in order to improve preparedness, and learn more about how an infectious disease, such as COVID-19, might spread through a population, is agent-based epidemiological modelling. When a pandemic is caused by an emerging disease, it takes time to develop a completely new model that captures the complexity of the system. In this paper, we discuss adapting an existing agent-based model for the spread of measles in Ireland to simulate the spread of …

Phycobilins As Potent Food Bioactive Broad-Spectrum Inhibitors Against Proteases Of Sars-Cov-2 And Other Coronaviruses: A Preliminary Study, Brahmaiah Pendyala, Ankit Patras, Chandravanu Dash

Agricultural and Environmental Sciences Faculty Research

In the 21st century, we have witnessed three coronavirus outbreaks: SARS in 2003, MERS in 2012, and the ongoing pandemic coronavirus disease 2019 (COVID-19). The search for efficient vaccines and development and repurposing of therapeutic drugs are the major approaches in the COVID-19 pandemic research area. There are concerns about the evolution of mutant strains (e.g., VUI – 202012/01, a mutant coronavirus in the United Kingdom), which can potentially reduce the impact of the current vaccine and therapeutic drug development trials. One promising approach to counter the mutant strains is the “development of effective broad-spectrum antiviral drugs” against coronaviruses. This …
