Pulmonary rehabilitation focusing on the regulation of respiratory movement can improve prognosis of severe patients with COVID-19.

Background: Since the coronavirus disease 2019 (COVID-19) emerged in Wuhan, China, it has become a global public health emergency. Besides conventional care, pulmonary rehabilitation (PR) is an equally important treatment for patients with COVID-19 suffering from respiratory, physical and psychological disease. The aim of this study is to investigate the role of PR on the inpatients with severe COVID-19.

An upconversion nanoparticle-based photostable FRET system for long-chain DNA sequence detection.

The fluorescence resonance energy transfer (FRET)-based diagnosis method has been widely used in fast and accurate diagnosis. However, the traditional FRET-based diagnosis method is unable to detect long-chain DNA sequences, due to the limitation of the distance between the donor and acceptor, while the long-chain DNA sequence enables higher selectivity and is quite important for confirming many major diseases. Therefore, it is urgently needed to develop an efficient FRET system for long-chain DNA detection.
