CHANGES WITHIN THE P681 RESIDUE OF SPIKE DICTATE CELL FUSION AND SYNCYTIA FORMATION OF DELTA AND OMICRON VARIANTS OF SARS-COV-2 WITH NO EFFECTS ON NEUTRALIZATION OR INFECTIVITY

The rapid spread and dominance of the Omicron SARS-CoV-2 lineages have posed severe health challenges worldwide.While extensive research on the role of the Receptor Binding Domain (RBD) in promoting viral infectivity and vaccine sensitivity has been well documented, the functional significance of the 681PRRAR/SV687 polybasic motif of the viral spik

The tradition Canopies of developmental psychology as been of fundamental importance in providing versions of musical childhoods, particularly for the earliest years of childhood.However, in its focus on the individual child and in its search for musical behaviors assumed to be common across all children, developmental psychology has tended to be i

The development of automation and intelligence in geological core drilling is not yet mature.The Teeth Whiteners selection and improvement of drilling parameters rely mainly on experience, and adjustments are often made after drilling by evaluating the core, which introduces a lag and reduces the drilling efficiency.Therefore, this study first esta

Mycobacterial heat shock protein 65 gene (Hsp65) has been widely used for classification of Mycobacterial species, and detection of Mycobacterial genes by molecular methods and has proven useful in identification of Mycobacterial infection in various clinical conditions.Circulating antibody against Mycobacterial hsp65 has been found in many clinica
