A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, EarlyView.
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.

Tacrolimus exposure during pregnancy in kidney and liver transplantation recipients: A comparison between whole blood and plasma concentration‐to‐dose ratios

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Tacrolimus monitoring is generally performed in whole blood (WB). Most (>85%) of circulating tacrolimus is bound to red blood cells. During pregnancy, WB monitoring might be suboptimal because of physiological changes including increased plasma volume and decreased haematocrit.

Bottom‐Up Ice Growth Geometry Attenuates Shear Stress and Improves the Cryopreservation of Hematopoietic Stem/Progenitor Cells Under Low DMSO Concentrations

Biotechnology and Bioengineering, EarlyView.
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 ...
