A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

ABSTRACT Studies on cell cryopreservation have been limited by the complexity of the freezing process and challenges on controlling ice formation, managing cooling rates, and optimizing cryoprotectant concentrations. The objective of this study is to evaluate the impact of bottom‐up and conventional radial freezing on the viability of mammalian cells ...

Evaluating Isochoric Freezing as a Strategy for Storage of Red Blood Cells
ABSTRACT Red blood cells (RBCs) are needed for life‐saving blood transfusions, but they undergo continuous degradation during storage. Preserving RBCs for clinical transfusion remains a challenge due to storage‐induced damage and limitations of traditional freezing methods.

Extracellular vesicles (EVs) derived from stem cells show promise for applications in regenerative medicine, but their scalability and yield remain challenges. This review explores the approaches for biophysical modulations within cell niches on EV properties, discusses the current clinical application of EVs, and provides an outlook on the existing ...
