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 …

Landscape-Based Mutational Sensitivity Cartography And Network Community Analysis Of The Sars-Cov-2 Spike Protein Structures: Quantifying Functional Effects Of The Circulating D614g Variant, Gennady M. Verkhivker, Steve Agajanian, Deniz Yasar Oztas, Grace Gupta

Mathematics, Physics, and Computer Science Faculty Articles and Research

We developed and applied a computational approach to simulate functional effects of the global circulating mutation D614G of the SARS-CoV-2 spike protein. All-atom molecular dynamics simulations are combined with deep mutational scanning and analysis of the residue interaction networks to investigate conformational landscapes and energetics of the SARS-CoV-2 spike proteins in different functional states of the D614G mutant. The results of conformational dynamics and analysis of collective motions demonstrated that the D614 site plays a key regulatory role in governing functional transitions between open and closed states. Using mutational scanning and sensitivity analysis of protein residues, we identified the stability …

Reflections Of An Earliest Established Screening And Testing Facility For Covid-19 In The Largest Metropolis, Pakistan, Fatima Kanwal, Karishma Kanhya Lal, Asra Qureshi

Department of Family Medicine

As the world struggles to deal with the COVID-19 pandemic, this article talks about the experience and findings of the first COVID-19 screening facility in a tertiary care hospital in Karachi, Pakistan. Department of Family Medicine at Aga Khan University (AKU) took initiative where COVID-19 screening of stable patients first began in a dedicated area. Since testing kits were limited and community spread had not started, nurses would screen every walk-in patient based on the presence of fever, cough, travel history and exposure to COVID-19 positive patient in the last 14 days, and advise swab testing if indicated. Out of …

Combating Hiv-1 By Targeting Drug Efflux Transporters On The Macrophage Reservoir, Ying Mu

Theses and Dissertations (ETD)

Introduction. HIV-1 eradication has not been achieved so far due to the existence of the cellular reservoir in which the virus can reside and replicate even under antiretroviral drug therapy (ART). Infected macrophages, which represent a long-term viral reservoir have been shown to lead to viral rebound independently. In response to the environmental stimuli, macrophages can be polarized into different phenotypes: the pro-inflammatory M1 and the anti-inflammatory M2. Tobacco smoking and alcohol drinking, which are prevalent among people who are living with HIV-1, have been shown to promote HIV-1 progression and decrease the efficacy of antiretroviral drugs. A commonly …

Mathematics, Physics, and Computer Science Faculty Articles and Research

In this study, we used an integrative computational approach to examine molecular mechanisms underlying functional effects of the D614G mutation by exploring atomistic modeling of the SARS-CoV-2 spike proteins as allosteric regulatory machines. We combined coarse-grained simulations, protein stability and dynamic fluctuation communication analysis with network-based community analysis to examine structures of the native and mutant SARS-CoV-2 spike proteins in different functional states. Through distance fluctuations communication analysis, we probed stability and allosteric communication propensities of protein residues in the native and mutant SARS-CoV-2 spike proteins, providing evidence that the D614G mutation can enhance long-range signaling of the allosteric spike …

A Guide To Vaccine Policy Change At A National Level, Janelle Bird

Doctor of Nursing Practice Final Manuscripts

Abstract

Health policy is in a near constant state of improvement. In order to solidify those improvements, health policy requires assistance from the upcoming generations of healthcare workers to push for those changes. Due to the outdated vaccination policy in the American Nurses Association (ANA), many states continued to issue exemptions based upon unsupported religious preferences. This helped to worsen the outbreak of measles in 2018-2019. The Previous ANA Policy on Vaccinations as of July 21, 2015 stated the ANA supports immunization exemptions only for the following reasons: Medical contraindications and Religious beliefs. Educate and train future health care professionals …

A Case Series Of Hyperglycemic Hyperosmolar State During The Global Covid-19 Pandemic, Benjamin Hoag

Research Days

Background: Hyperglycemic hyperosmolar state (HHS) is rare in pediatrics, particularly in patients with antibody positive diabetes mellitus (DM). Recent literature has implicated COVID-19 in the reported increase in new onset DM cases, as well as mixed diabetic ketoacidosis (DKA) and HHS cases; however, a rise in HHS cases alone has not been well reported [1,2]. We noted an anecdotal increase in the frequency of HHS cases in our pediatric tertiary care center following the onset of the global COVID-19 pandemic.

Objectives/Goal: To investigate further, a retrospective chart review evaluating all patients with DM admitted in the first 6 months of …
