Background: Chronic obstructive pulmonary disease (COPD) is characterized by airway inflammation, airflow limitation, reduced health-related quality of life (HRQL), and exercise intolerance. Pulmonary rehabilitation (PR) is essential for COPD management, but outcomes may be influenced by individual physiological factors. Cardiopulmonary exercise testing (CPET) measures oxygen pulse (O2P), an indicator of stroke volume, yet the impact of baseline O2P on PR effectiveness remains unclear.

Article Synopsis
  • Five new pregnane C21-steroids were identified from the roots of Cynanchum bungei, including three previously unknown 5,6-epoxy steroids and two 8,14-seco-steroids.
  • Compound 3 is notable for being the first 5a,6a-epoxy steroid discovered in Cynanchum plants, with their structures confirmed through various spectroscopic methods and theoretical calculations.
  • All isolated compounds showed anti-inflammatory properties by inhibiting nitric oxide release in RAW264.7 cells, with compounds 3 and 4 demonstrating stronger activity than the commonly used anti-inflammatory drug indomethacin at a concentration of 50 μM.

Electrochemical CO capture driven by renewable electricity holds significant potential for efficient decarbonization. However, the widespread adoption of this approach is currently limited by issues such as instability, discontinuity, high energy demand, and challenges in scaling up. In this study, we propose a scalable strategy that addresses these limitations by transforming the conventional single-step electrochemical redox reaction into a stepwise electrochemical-chemical redox process.

The adverse effect of ambient PM exposure on very early pregnancy (VEP) remains controversial among epidemiological studies but is supported by toxicological evidence. We adopted a multicenter retrospective cohort of 141,040 cycles to evaluate the effect of PM exposure on the VEP using the fertilization and embryo transfer platform and high-resolution PM data in China. We first investigated the association between PM exposure 1 week before and 1 week after the embryo transfer date and VEP.
