Roles Of A Bradykinin Storm And A Cytokine Storm In Covid-19 Cases, Nouha H. Odeh

Honors College Theses

In the light of recent events, it is imperative to understand the key inflammatory response elements that appear to be the source of more severe ailments resulting from a SARS-CoV-2 viral infection known as Covid-19 The more severe cases of Covid-19 are characterized by a severe inflammatory response resulting in tissue damage. My research proposal aims to investigate the two possible culprits of this response: a bradykinin (BK) storm and an interleukin-6 (IL-6) mediated cytokine storm. In both systems respectively, the excess release of these signals subsequently signals the production of even more of the same response element, resulting in …

The current COVID-19 pandemic urges the extremely sensitive and prompt detection of SARS-CoV-2 virus. Here, we present a Human Angiotensin-converting-enzyme 2 (ACE2)-functionalized gold “virus traps” nanostructure as an extremely sensitive SERS biosensor, to selectively capture and rapidly detect S-protein expressed coronavirus, such as the current SARS-CoV-2 in the contaminated water, down to the single-virus level. Such a SERS sensor features extraordinary 106- fold virus enrichment originating from high-affinity of ACE2 with S protein as well as “virus-traps” composed of oblique gold nanoneedles, and 109- fold enhancement of Raman signals originating from multicomponent SERS effects. Furthermore, the identification standard of virus …

High Prevalence Of Pre-Existing Serological Cross-Reactivity Against Severe Acute Respiratory Syndrome Coronavirus-2 (Sars-Cov-2) In Sub-Saharan Africa, For Yue Tso, Salum J. Lidenge, Phoebe B.

Objective: Significant morbidity and mortality have occurred in the USA, Europe, and Asia due to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), whereas the numbers of infections and deaths in sub-Saharan Africa (SSA) have remained comparatively low. It has been hypothesized that exposure of the population in SSA to other coronaviruses prior to the COVID-19 pandemic resulted in some degree of cross-protection against SARS-CoV-2 infection and pathogenesis. We evaluated this hypothesis by comparing SARS-CoV-2 cross-reactive antibodies in pre-pandemic plasma samples collected from SSA and the USA.

Method: Pre-COVID-19 pandemic plasma samples from SSA and the USA were collected and tested by …
