Psychological Impact Of Novel Coronavirus Covid-19 Across The Globe-A Review, Sadaf Shaheen, Iram Asim, Rida Zainab, Humaira Yasmeen
Journal of Bioresource Management
The recent outbreaks of novel coronavirus disease have unprecedent impact on mental health of patients, front-line healthcare workers and local population. However, the impact is not fully documented. This review explores stress-driven factors, stress-vulnerable groups and stress management interventions. Repetitive exposure to mass media and inappropriate health protective measures has heightened stress responses. Fear of not getting recovered from COVID-19 and disaffection has profound impact of infected individuals and their families. They may experience fear, anxiety, anger, sleep deprives and anorexia which may weakens their immune system thus making them vulnerable to COVID-19. The COVID-19 pandemic has underscored potential gaps ...

Investigating The Sars-Cov-2 Orf 8 Accessory Protein: Expression, Purification, And Structural Determination, 2021 Kennesaw State University
Investigating The Sars-Cov-2 Orf 8 Accessory Protein: Expression, Purification, And Structural Determination, Laney Hedgeman, Caroline Salha
Symposium of Student Scholars
In order to provide insight into potential therapeutic breakthroughs for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), more research must be done to understand the structure and function of its proteins. The open reading frame 8 (ORF 8) accessory protein is particularly unstable on its own outside of the viral envelope but can be stabilized when bound to the small ubiquitin-related modifier (SUMO) protein. The stable ORF 8-SUMO protein complex can be expressed and purified using familiar techniques and later characterized with nuclear magnetic resonance (NMR) spectroscopy, thus allowing us to gain knowledge about the role it plays ...

Proteomic Analysis Of Mycobacteriophage Crimd, 2021 William & Mary
Proteomic Analysis Of Mycobacteriophage Crimd, William Moeller
Undergraduate Honors Theses
Bacteriophages represent a large portion of the biomatter on our planet, and many of them have yet to be fully characterized. Here we discuss the proteomic analysis of a particular Bacteriophage, Mycobacteriophage CrimD. This phage was discovered on the Campus of William & Mary and has had its genome characterized. We took the next logical step of proteomic analysis.
In our analyses we made use high pressure liquid chromatography paired with linear ion trap mass spectrometry to analyze the proteome of CrimD at specific time points after the infection of its host, Mycobacterium smegmatis. Additionally, we used nanospray ionization with in-house ...
Sodium Pyruvate Ameliorates Influenza A Virus Infection In Vitro And In Vivo, 2021 Missouri State University
Sodium Pyruvate Ameliorates Influenza A Virus Infection In Vitro And In Vivo, Jessica M. Reel
MSU Graduate Theses
Pyruvate is produced in duplicate at the end of glycolysis in addition to ATP and NADH. Pyruvate is the metabolite of choice in most cells, whether obtained exogenously or endogenously. Recently we found that the addition of pyruvate’s conjugate base, sodium pyruvate, to cell culture media dampened the immune response to influenza A virus (IAV) infection in cultured innate immune cells. Thus, I decided to investigate the mechanism and potential for treatment of IAV. In vitro using bone marrow derived macrophages that were infected with IAV we found that adding sodium pyruvate to the media decreased immune signaling pathways ...
Hiv-1 Drug Resistance To Integrase Strand Transfer Inhibitors In Hiv-1 Non-B Subtypes, 2021 The University of Western Ontario
Hiv-1 Drug Resistance To Integrase Strand Transfer Inhibitors In Hiv-1 Non-B Subtypes, Emmanuel Ndashimye
Electronic Thesis and Dissertation Repository
Human immunodeficiency syndrome (HIV-1) has infected over 75 million people and over 35 million have succumbed to virus related illnesses. Despite access to a variety of antiretroviral therapy (ART) options, ART programs have been disproportionally spread in the world with low-and middle-income countries (LMICs) facing challenges to access the most potent ART options. With less potent ART remaining in use in LMICs, HIV-1 drug resistance (HIVDR) presents a growing challenge in LMICs. Since approval of the first-generation integrase strand transfer inhibitor (INSTIs), Raltegravir (RAL) in 2007, INSTIs remain the best choice as a backbone of ART. Access to second generation ...

B16: Chikungunya Virus Time Course Infection Of Human Macrophages, Madison Gray, Israel Guerrero-Arguero, Antonio Solis Leal, Richard Robison, Brad Burges, Brett Pickett
Annual Research Symposium
Chikungunya virus (CHIKV) is an Alphavirus spread by Aedes spp. mosquitoes and is responsible for infecting 1.1 million people per year worldwide, including a large epidemic in the western hemisphere in 2014-2015. During the body’s immune response to CHIKV, human macrophages become infected after phagocytosis of CHIKV and undergo induced apoptosis, catalyzing the virus spread in the body. It is presently unclear what macrophage genes, functions, and intracellular signaling pathways are impacted during the early, intermediate, and late stages of CHIKV infection. Therefore we quantified the transcriptional response of human macrophage cells infected with CHIKV at two different ...
Characterization Of Novel Chlorovirus Glycosyltransferases That Synthesize Atypical Glycans, 2021 University of Nebraska-Lincoln
Characterization Of Novel Chlorovirus Glycosyltransferases That Synthesize Atypical Glycans, Eric Noel
Dissertations and Theses in Biological Sciences
Giant dsDNA chloroviruses encode a diverse repertoire of glycosyltransferases (GTases) and methyltransferases (MTases) that biosynthesize unusual, methylated sugars independent of their host chlorella-like green algae prompting a reexamination of glycobiology systems. Unlike most other viruses, the prototype chlorovirus PBCV-1 encodes most, if not all, of the machinery required to glycosylate its major capsid protein (MCP). The structures of the four N-linked glycans do not resemble any other glycans in the three domains of life. Here, we investigated the potential involvement of chlorovirus- encoded putative GTases and MTases in glycosylation of the viral MCP. First, we aimed to generate site-directed ...
Effectiveness Of Pathogen-Specific Passive Antibodies To Mitigate Infectious Diseases In Apis Mellifera, 2021 University of South Dakota
Effectiveness Of Pathogen-Specific Passive Antibodies To Mitigate Infectious Diseases In Apis Mellifera, Tanner Nordseth
Honeybees (Apis mellifera) are widely recognized as a vital part of the global ecosystem and the world's food supply due to their pivotal role in the pollination of both natural and agricultural flora. Colony Collapse Disorder (CCD) is an emerging phenomenon characterized by a colony's worker bees deserting the hive and leaving the queen behind. This usually results in colony failure. CCD is a multifactorial issue, with many environmental stressors and pathogens playing a role. Deformed Wing Virus (DWV) has been identified as a leading cause in this phenomenon. Paenibacillus larvae (P. larvae) is another lethal pathogen that ...
Characterization Of Crispr Spacer And Protospacer Sequences In Paenibacillus Larvae And Its Bacteriophages, 2021 University of Nevada, Las Vegas
Characterization Of Crispr Spacer And Protospacer Sequences In Paenibacillus Larvae And Its Bacteriophages, Casey Stamereilers, Simon Wong, Philippos K. Tsourkas
Life Sciences Faculty Publications
The bacterium Paenibacillus larvae is the causative agent of American foulbrood, the most devastating bacterial disease of honeybees. Because P. larvae is antibiotic resistant, phages that infect it are currently used as alternative treatments. However, the acquisition by P. larvae of CRISPR spacer sequences from the phages could be an obstacle to treatment efforts. We searched nine complete genomes of P. larvae strains and identified 714 CRISPR spacer sequences, of which 384 are unique. Of the four epidemiologically important P. larvae strains, three of these have fewer than 20 spacers, while one strain has over 150 spacers. Of the 384 ...

Antibodies elicited in response to infection undergo somatic mutation in germinal centers that can result in higher affinity for the cognate antigen. To determine the effects of somatic mutation on the properties of SARS-CoV-2 spike receptor-binding domain (RBD)-specific antibodies, we analyzed six independent antibody lineages. As well as increased neutralization potency, antibody evolution changed pathways for acquisition of resistance and, in some cases, restricted the range of neutralization escape options. For some antibodies, maturation apparently imposed a requirement for multiple spike mutations to enable escape. For certain antibody lineages, maturation enabled neutralization of circulating SARS-CoV-2 variants of concern and ...
Inhibition Of Zika Virus Replication By G-Quadruplex-Binding Ligands, 2021 Indian Institute of Technology Indore
Inhibition Of Zika Virus Replication By G-Quadruplex-Binding Ligands, Indian Institute Of Technology Indore, Aryamav Pattnaik, Bikash R. Sahoo, Uma Shankar, Asit K. Pattnaik, Amit Kumar, Debasis Nayak
Zika virus (ZIKV), a mosquito-transmitted Flavivirus, emerged in the last decade causing serious diseases and affecting human health globally. Currently, no licensed vaccines or antivirals are available to combat ZIKV, although several vaccine candidates are in the pipeline. In recent years, the presence of non-canonical G-quadruplex (GQ) secondary structures in viral genomes has ignited significant attention as potential targets for antiviral strategy. In this study, we identified several novel conserved potential GQ structures by analyzing published ZIKV genome sequences using an in-house algorithm. Biophysical and biochemical analysis of the RNA sequences containing these potential GQ sequences suggested the existence of ...

The current study aims to develop a safe and highly immunogenic COVID-19 vaccine. The novel combination of a DNA vaccine encoding the full-length Spike (S) protein of SARS-CoV-2 and a recombinant S1 protein vaccine induced high level neutralizing antibody and T cell immune responses in both small and large animal models. More significantly, the co-delivery of DNA and protein components at the same time elicited full protection against intratracheal challenge of SARS-CoV-2 viruses in immunized rhesus macaques. As both DNA and protein vaccines have been proven safe in previous human studies, and DNA vaccines are capable of eliciting germinal center ...

Broadly neutralizing antibodies (bnAbs) targeting conserved influenza A virus (IAV) hemagglutinin (HA) epitopes can provide valuable information for accelerating universal vaccine designs. Here, we report structural details for heterosubtypic recognition of HA from circulating and emerging IAVs by the human antibody 3I14. Somatic hypermutations play a critical role in shaping the HCDR3, which alone and uniquely among VH3-30 derived antibodies, forms contacts with five sub-pockets within the HA-stem hydrophobic groove. 3I14 light-chain interactions are also key for binding HA and contribute a large buried surface area spanning two HA protomers. Comparison of 3I14 to bnAbs from several defined ...

COVID-19 Publications by UMMS Authors
Viral proteases are critical enzymes for the maturation of many human pathogenic viruses and thus are key targets for direct acting antivirals (DAAs). The current viral pandemic caused by SARS-CoV-2 is in dire need of DAAs. The Main protease (M(pro)) is the focus of extensive structure-based drug design efforts which are mostly covalent inhibitors targeting the catalytic cysteine. ML188 is a non-covalent inhibitor designed to target SARS-CoV-1 M(pro), and provides an initial scaffold for the creation of effective pan-coronavirus inhibitors. In the current study, we found that ML188 inhibits SARS-CoV-2 M(pro) at 2.5 microM, which is ...

BACKGROUND: Risk of severe coronavirus disease 2019 (COVID-19) increases with age, is greater in males, and is associated with decreased numbers of blood lymphoid cells. Though the reasons for these robust associations are unclear, effects of age and sex on innate and adaptive lymphoid subsets, including on homeostatic innate lymphoid cells (ILCs) implicated in disease tolerance, may underlie the effects of age and sex on COVID-19 morbidity and mortality.
METHODS: Flow cytometry was used to quantitate subsets of blood lymphoid cells from people infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), comparing those hospitalized with severe COVID-19 (n=40 ...

Adenovirus has made major contributions in medicine by serving as a model DNA virus to study other viruses, such as human papillomavirus (HPV). Adenoviruses are a diverse family of nonenveloped, double-stranded DNA viruses that are ubiquitous to animals and humans. There are over 67 serotypes of human adenoviruses that can cause a variety of illnesses including, gastroenteritis, conjunctivitis and respiratory infections. Adenovirus can cause these infections by invading host cells and producing an environment that is favorable for viral replication. During the early phases of infection, adenovirus expresses various viral proteins such as E4 11k, which has multiple functions. One ...
