Diagnostic dilemma: Low oxygen saturation during cardiac surgery

Annals of Cardiac Anaesthesia, 2017
We report a case of rheumatic heart disease with severe mitral stenosis having cyanosis and low oxygen saturation on pulse oximetry. The findings of clinical examination and low values on pulse oximetry were inconsistent with the findings of normal ...

Organic Bulk‐Heterojunction‐Integrated Flexible Perovskite Photodetection Arrays for High‐Speed Broadband Optical Communication

Advanced Science, EarlyView.
A flexible broadband photodetector is realized by integrating a perovskite with an organic bulk‐heterojunction. It achieves high external quantum efficiency (EQE) (>80% visible, >60% near‐infrared (NIR)), ultralow dark current, and fast response, enabling self‐powered, high‐detectivity operation.

Targeting DNA‐LNPs to Endothelial Cells Improves Expression Magnitude, Duration, and Specificity

Advanced Science, EarlyView.
Attaching antibodies against endothelial cell surface proteins redirects the delivery and expression of DNA‐lipid nanoparticles to organs of interest. Our targeted nanoparticles enable organ‐selective DNA expression in the endothelium of the lungs, brain, or spleen, providing a therapeutic platform for dozens of endothelial‐centric diseases.
