Respiratory microbiota and radiomics features in the stable COPD patients.

Backgrounds: The respiratory microbiota and radiomics correlate with the disease severity and prognosis of chronic obstructive pulmonary disease (COPD). We aim to characterize the respiratory microbiota and radiomics features of COPD patients and explore the relationship between them.

Methods: Sputa from stable COPD patients were collected for bacterial 16 S rRNA gene sequencing and fungal Internal Transcribed Spacer (ITS) sequencing.

Automated interpretation of the pulmonary function test by a portable spirometer in Chinese adults.

Introduction: A portable spirometer is a promising alternative to a traditional pulmonary function test (PFT) spirometer for respiratory function evaluation.

Objectives: This study aimed to investigate the accuracy of automated interpretation of the PFT measured by a portable Yue Cloud spirometer in Chinese adults.

Methods: The PFT was performed to evaluate subjects prospectively enrolled at Ruijin Hospital (n = 220).

Experimental Research on Stability and Natural Convection of TiO-Water Nanofluid in Enclosures with Different Rotation Angles.

The stability and natural convection heat transfer characteristics of TiO-water nanofluid in enclosures with different rotation angles (α = -45°, α = 0°, α = 45°, and α = 90°) are experimentally investigated. The effects of different pH values and doses (m) of dispersant agent on the stability of TiO-water nanofluid are investigated. It is found that TiO-water nanofluid with m = 6 wt% and pH = 8 has the lowest transmittance and has the best stability.
