FEATURING ENSO 1997-2000 IN CENTRAL CHILE

Gayana (Concepción), 2004
Using satellite images of the area between 32-36°S and 71-75°W, from October 1997 to September 1999, temporal and spatial variability of sea surface temperature (SST) was analyzed. During this period of time, one of the most intense episode of the last century of the warm phase (El Niño) and the beginning of the cold phase (La Niña) of the ENSO cycle ...

Radiation‐Resistant Bacteria Deinococcus radiodurans‐Derived Extracellular Vesicles as Potential Radioprotectors

Advanced Healthcare Materials, EarlyView.
Deinococcus radiodurans‐derived extracellular vesicles (R1‐EVs) provide radioprotection against total‐body irradiation‐induced acute radiation syndrome in mice. R1‐EVs mitigate oxidative damage by scavenging free radicals, promoting intestinal repair, enhancing hematopoietic function, and modulating immune responses. This study highlights the potential

Covalent Binding of Dexamethasone to Polyimide Improves Biocompatibility of Neural Implantable Devices

Advanced Healthcare Materials, EarlyView.
The covalent binding of dexamethasone to the surface of polyimide represents the electrically inert part of implantable intraneural devices. This ensures a sustained release of the drug for 9 weeks. In vitro and in vivo tests confirm the reduction of the foreign body reactions and the improved biocompatibility of dexamethasone functionalized polyimide.
