Scientists at the University of California, San Francisco (UCSF) have engineered molecules that act like “cellular glue,” allowing them to direct in precise fashion how cells bond with each other. The discovery represents a major step toward building tissues and organs, a long-sought goal of regenerative medicine.

Adhesive molecules are found naturally throughout the body, holding its tens of trillions of cells together in highly organized patterns. They form structures, create neuronal circuits, and guide immune cells to their targets. Adhesion also facilitates communication between cells to keep the body functioning as a self-regulating whole.

In a new study, published in the December 12, 2022, issue of Nature, researchers engineered cells containing customized adhesion molecules that bound with specific partner cells in predictable ways to form complex multicellular ensembles.

Researchers have finally succeeded in building a long-sought nanoparticle structure, opening the door to new materials with special properties.

Alex Travesset does not have a sparkling research lab stocked with the most cutting-edge instruments for probing new nanomaterials and measuring their unique properties.

Instead of using traditional laboratory instruments, Alex Travesset, a professor of physics and astronomy at Iowa State University and an affiliate of the U.S. Department of Energy’s Ames National Laboratory, relies on computer models, equations, and figures to understand the behavior of new nanomaterials.

Lupin Pharmaceuticals issued a voluntary recall of some blood pressure medication due to the potential presence of a nitrosamine impurity, according to a notice published on the Food and Drug Administration’s (FDA) website.

The recall, issued last week, includes one batch of 20-milligram Quinapril Tablets USP — G102929 — and three batches of 40-milligram Quinapril Tablets USP – G100533, G100534 and G203071, the notice said.

Consumers, wholesalers, distributors and retailers can find the lot number on the side of the label affixed to bottles.
