Publications and Research

Botanical therapeutics possess a unique potential in the treatment of viral diseases. The pharmacological base and clinical use of botanical therapeutics have been extensively reviewed. The mode of action(s) may be built either on the direct interference with the virus's ability to enter human cells, virus replication, or exerting immune-modulatory and anti-inflammatory effects. The adjuvant treatment with botanical therapeutics has the potential to result in advances in symptom resolution, decrease in disease burden and shortening its duration.


Advancing Rna Virus Discovery And Biology With Whole Genome Sequencing, Mariah Katherine Taylor Nov 2021

Advancing Rna Virus Discovery And Biology With Whole Genome Sequencing, Mariah Katherine Taylor

Theses and Dissertations (ETD)

Two RNA virus families that pose a threat to human and animal health are Hantaviridae and Coronaviridae. These RNA viruses which originate in wildlife continue and will continue to cause disease, and hence, it is critical that scientific research define the mechanisms as to how these viruses spillover and adapt to new hosts to become endemic. One gap in our ability to define these mechanisms is the lack of whole genome sequences for many of these viruses. To address this specific gap, I developed a versatile amplicon-based whole-genome sequencing (WGS) approach to identify viral genomes of hantaviruses and severe acute …

Department of Biological & Biomedical Sciences

The SARS-CoV-2 pandemic has created a public health crisis worldwide. Although vaccines against the virus are efficiently being rolled out, they are proving to be ineffective against certain emerging SARS-CoV-2 variants. The high degree of sequence similarity between SARS-CoV-2 and other human coronaviruses (HCoV) presents the opportunity for designing vaccines that may offer protection against SARS-CoV-2 and its emerging variants, with cross-protection against other HCoVs. In this study, we performed bioinformatics analyses to identify T and B cell epitopes originating from spike, membrane, nucleocapsid, and envelope protein sequences found to be evolutionarily conserved among seven major HCoVs. Evolutionary conservation of …

Molecular and Cellular Biochemistry Faculty Publications

The trimeric severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein (S) is the sole viral protein responsible for both viral binding to a host cell and the membrane fusion event needed for cell entry. In addition to facilitating fusion needed for viral entry, S can also drive cell-cell fusion, a pathogenic effect observed in the lungs of SARS-CoV-2-infected patients. While several studies have investigated S requirements involved in viral particle entry, examination of S stability and factors involved in S cell-cell fusion remain limited. A furin cleavage site at the border between the S1 and S2 subunits (S1/S2) has …


Coagulopathy In Covid-19: A Review, Shannon Ginty Jun 2021

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 …
