Mutations in SARS-CoV-2 spike proteolytic cleavage sites may alter transmission dynamics

A study conducted by researchers at the University of Kentucky and the Washington University School of Medicine in the USA has revealed that mutations in the proteolytic cleavage site within the S2 subunit can alter the processing of the SARS-CoV-2 spike protein, affecting viral entry into host cells.

Women need to be educated about the warning signs and symptoms of preeclampsia

Each year, thousands of women and their babies die or get very sick from preeclampsia, a serious and potentially life-threatening condition that occurs during pregnancy and occasionally during the first few weeks following childbirth. High blood pressure during pregnancy is one of the warning signs.
