The efficacy and safety of remimazolam besylate, ciprofol, and propofol during hysteroscopy.

Objective: Remimazolam besylate and Ciprofol are newer sedatives used in minor surgeries. Propofol is a classic drug mainly used for short surgeries. This trial was conducted to compare the efficacy and safety of remimazolam besylate, ciprofol, and propofol during hysteroscopic surgeries.

Impacts of meteorology and precursor emission change on PM and O and identification of synergistic emission reduction pathway: A case of combined pollution event in Beijing, China.

Given the leveling off of PM, the coordinated control of PM and O has become a critical challenge in the Beijing-Tianjin-Hebei (BTH) region. Here, we leveraged long-term observation data spanning 2013 to 2023 to reveal spatiotemporal heterogeneity, provincial spatial correlation, and driving factors influencing PM and O integrating Moran's Index and correlation analysis. Additionally, sensitivity experiments on precursor emission reduction focusing on both overall and key sources were conducted by combining WRF-CAMx models and the empirical kinetic modeling approach (EKMA), and synergistic emission reduction pathways were proposed during periods of combined pollution.

L-Cysteine Treatment Delays Leaf Senescence in Chinese Flowering Cabbage by Regulating ROS Metabolism and Stimulating Endogenous HS Production.

Leaf senescence is a major concern for postharvest leafy vegetables, as leaves are highly prone to yellowing and nutrient loss, resulting in reduced commercial value and limited shelf-life. This study aimed to investigate the effect of L-cysteine (L-cys) on postharvest Chinese flowering cabbage stored at 20 °C. The results showed that 0.

Anaerobic 1,2-/1,3-Hydroxytrifluoromethylation of Unactivated Alkenes Enabled by Photoexcited Nitroarenes.

An anaerobic 1,2-/1,3-hydroxytrifluoromethylation of unactivated alkenes is described. This reaction proceeds in mild and environmentally friendly conditions without photocatalyst and metal catalyst, allowing access to a wide range of β- and γ-trifluoromethyl alcohols. Preliminary mechanistic investigations indicate that the accomplishment of this protocol relies on the dual functionality of the photoexcited triplet nitroarenes, which serve as the oxygen atom source and enable the single-electron transfer (SET) process with CFSONa.

Sodium hydrosulfide application induces chilling tolerance in banana fruits by enhancing antioxidant gene expression through the upregulation of the ethylene response factors MaERF53L/121L.

Sodium hydrosulfide (NaHS), a hydrogen sulfide (H₂S) donor, effectively mitigates chilling injury (CI) in bananas; however, the underlying molecular mechanisms remain unclear. This study demonstrated that NaHS alleviates CI symptoms by activating antioxidant defense systems that reduce oxidative stress induced by CI. Transcriptomic analysis revealed 1003 differentially expressed genes in three sample groups, with enrichment in pathways related to cellular processes, metabolic activity, and secondary metabolite biosynthesis.
