Designing and bioengineering of CDRs with higher affinity against receptor-binding domain (RBD) of SARS-CoV-2 Omicron variant.

The emergence of the SARS-CoV-2 Omicron variant highlights the need for innovative strategies to address evolving viral threats. This study bioengineered three nanobodies H11-H4, C5, and H3 originally targeting the Wuhan RBD, to bind more effectively to the Omicron RBD. A structure-based in silico affinity maturation pipeline was developed to enhance their binding affinities.

Remineralizing Agents: The Next Frontier.

Remineralizing agents represent a new frontier in dentistry. They may be classified as fluoride agents, calcium and phosphate based agents, herbal agents or combinations. The modes of delivery of remineralizing agents may be as dentifrices, mouth rinses, lozenges or chewing gums.
