Study may pave the way for mechano-medical approaches to treating abdominal aortic aneurysm

Abdominal aortic aneurysm (AAA) is a complex and life-threatening vascular disease with high incidence worldwide. Termed the silent killer, most AAAs are asymptomatic, often going undetected until rupture, and involve a poorly understood set of mechanical and biochemical events.

Exploring factors favoring transmission of SARS-CoV-2 Delta sublineage AY.4.2 over the Delta variant

In the present study, researchers isolated an infectious AY.4.2 strain of COVID-19 from the nasopharyngeal swab of a symptomatic individual from the Paris region. Then, they introduced the AY.4.2 signature mutations - T95I, Y145H, and A222V - in an expression plasmid coding the Delta protein to study the function of the AY.4.2 S protein.
