Photoinduced Alkylsulfonylation and Cyanoalkylsulfonylation of Morita-Baylis-Hillman Adducts via Multicomponent Insertion of Sulfur Dioxide.

General and convenient visible-light-promoted alkylsulfonylation and cyanoalkylsulfonylation of MBH adducts have been developed through the multicomponent insertion of sulfur dioxide, enabling the assembly of two C-S bonds to generate structurally diverse allylic alkylsulfones (43 examples in total). The reaction of MBH adducts with potassium alkyltrifluoroborates and 1,4-diazabicyclo[2.2.

The effect of continuous midwifery services on the delivery mode, labor progress, and nursing satisfaction of primiparas during natural deliveries.

Objective: To analyze the effect of continuous midwifery services on the delivery mode, labor progress, and primiparas' nursing satisfaction levels during natural deliveries.

Methods: 340 primiparas admitted to our hospital from January 2017 to June 2020 were recruited as the study cohort and randomized into a continuous midwifery group and a traditional midwifery group, with 170 patients in each group. They underwent traditional midwifery nursing services and continuous midwifery services, respectively.

Dual RNA-seq uncovers the immune response of Larimichthys crocea to the secY gene of Pseudomonas plecoglossicida from the perspective of host-pathogen interactions.

Pseudomonas plecoglossicida is a Gram-negative aerobic bacterium that causes high mortality and serious economic losses in some commercial marine fish. Expression of secY was found to be significantly upregulated at 18 °C compared to 28 °C by RNA-seq and qRT-PCR. All five tested recombinant vectors (pCM130/tac + shRNA) significantly reduced secY mRNA levels in P.
