Alex Sigal
Alex Sigal is a South Africa–based virologist at the Africa Health Research Institute (AHRI) in Durban, South Africa, Max Plank Institute for Infection Biology in Berlin, and University of KwaZulu-Natal in Durban. His work concentrates on evolution and persistence of the SARS-CoV-2 virus. His laboratory was the first to isolate the live B.1.351 (Beta) variant of SARS-CoV-2 first detected in South Africa. Sigal’s laboratory was also the first to report results on the ability of the Omicron variant to escape antibody neutralization in individuals who had two doses of the Pfizer BNT162b2 vaccine as well as from previous infections, with results also suggesting that vaccination combined with a booster or previous infection can offer protection from symptomatic infection with Omicron. Education Sigal earned his bachelor's degree from the University of Toronto, Master's degree from the Weizmann Institute of Science, and PhD in Systems Biology from the Weizmann Institute of Science ...

Uri Alon
Uri Alon (Hebrew: אורי אלון; born 1969) is a Professor and Systems Biologist at the Weizmann Institute of Science. His highly cited research investigates gene expression, network motifs and the design principles of biological networks in ''Escherichia coli'' and other organisms using both computational biology and traditional experimental wet laboratory techniques. Education Alon earned his bachelor's and master's degrees from the Hebrew University of Jerusalem and his Ph.D. in Theoretical Physics from the Weizmann Institute of Science.

SARS-CoV-2 Beta Variant
The Beta variant, (B.1.351), was a variant of SARS-CoV-2, the virus that causes COVID-19. One of several SARS-CoV-2 variants initially believed to be of particular importance, it was first detected in the Nelson Mandela Bay metropolitan area of the Eastern Cape province of South Africa in October 2020, which was reported by the country's health department on 18 December 2020. Phylogeographic analysis suggests this variant emerged in the Nelson Mandela Bay area in July or August 2020. The World Health Organization labelled the variant as Beta variant, not to replace the scientific name but as a name for the public to commonly refer to. The WHO considers it to be a variant of concern no longer in circulation. Names The variant is also known as the ''South African variant''. Mutations File:SARS-CoV-2 Beta variant.svg, Amino acid mutations of SARS-CoV-2 Beta variant plotted on a genome map of SARS-CoV-2 with a focus on Spike. There are three mutations of particular interes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SARS-CoV-2 Omicron Variant
Omicron (B.1.1.529) is a variant of SARS-CoV-2 first reported to the World Health Organization (WHO) by the Network for Genomics Surveillance in South Africa on 24 November 2021. It was first detected in Botswana and has spread to become the predominant variant in circulation around the world. Following the original BA.1 variant, several subvariants of Omicron have emerged: BA.2, BA.3, BA.4, and BA.5. Since October 2022, two subvariants of BA.5 named BQ.1 and BQ.1.1 have spread rapidly. Three doses of a COVID-19 vaccine provide protection against severe disease and hospitalisation caused by BA.1 and BA.2. The immunity effects of BA.2 are similar to those of BA.1. For three-dose vaccinated individuals, the BA.4 and BA.5 variants are more infectious than previous subvariants, making it likely, , for a new peak in COVID-19 infections to occur. __TOC__ Classification On 26 November, the WHO's Technical Advisory Group on SARS-CoV-2 Virus Evolution declared PANGO linea ...

SARS-CoV-2 Delta Variant
The Delta variant (B.1.617.2) was a variant of SARS-CoV-2, the virus that causes COVID-19. It was first detected in India in late 2020. The Delta variant was named on 31 May 2021 and had spread to over 179 countries by 22 November 2021. The World Health Organization (WHO) indicated in June 2021 that the Delta variant was becoming the dominant strain globally. It has mutations in the gene encoding the SARS-CoV-2 coronavirus spike protein, spike protein causing the substitutions T478K, Variants of SARS-CoV-2#P681R, P681R and Variants of SARS-CoV-2#L452R, L452R, which are known to affect transmissibility of the virus as well as whether it can be neutralised by antibodies for previously circulating variants of the COVID-19 virus. In August 2021, Public Health England (PHE) reported secondary attack rate in household contacts of non-travel or unknown cases for Delta to be 10.8% ''vis-à-vis'' 10.2% for the SARS-CoV-2 Alpha variant, Alpha variant; the case fatality rate for those ...

Virologists
Virology is the scientific study of biological viruses. It is a subfield of microbiology that focuses on their detection, structure, classification and evolution, their methods of infection and exploitation of host cells for reproduction, their interaction with host organism physiology and immunity, the diseases they cause, the techniques to isolate and culture them, and their use in research and therapy. The identification of the causative agent of tobacco mosaic disease (TMV) as a novel pathogen by Martinus Beijerinck (1898) is now acknowledged as being the official beginning of the field of virology as a discipline distinct from bacteriology. He realized the source was neither a bacterial nor a fungal infection, but something completely different. Beijerinck used the word "virus" to describe the mysterious agent in his 'contagium vivum fluidum' ('contagious living fluid'). Rosalind Franklin proposed the full structure of the tobacco mosaic virus in 1955. Virology began ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Toronto Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...
