Transversus abdominis plane block improves postoperative recovery following cesarean delivery under general anesthesia: A propensity score matched retrospective cohort study.

Objective: To evaluate the effects of transversus abdominis plane (TAP) block on postoperative recovery 24 h after cesarean delivery under general anesthesia.

Methods: A propensity-score-matched, retrospective cohort study was used. A total of 173 pregnancies resulting in elective cesarean delivery under general anesthesia between March 2021 and March 2022 were analyzed retrospectively.

All-natural oil-in-water high internal phase Pickering emulsions featuring interfacial bilayer stabilization.

Hypothesis: Synergistic stabilization of high internal phase Pickering emulsions (HIPPEs) by food-grade colloidal particles are necessary for food, pharmaceuticals or cosmetics owing to their biocompatibility and multi-functionality. By tuning the interfacial structure of adsorbed binary particles, the HIPPE may exhibit extraordinary characteristics compared to conventional all-natural HIPPEs solely stabilized by single-component particle or composite particle, which should have potential applications in varies fields.

Experiments: HIPPEs were prepared by using zein protein nanoparticles (ZNPs) and starch nanocrystals (SNCs) as stabilizers.

Pickering Emulsions Simultaneously Stabilized by Starch Nanocrystals and Zein Nanoparticles: Fabrication, Characterization, and Application.

Using two types of colloidal particles having natural origins to synergistically stabilize Pickering emulsions is essential for food, cosmetics, and pharmaceutics, especially when neither particle can stabilize the Pickering emulsions alone. The use of two natural stabilizers avoids the complicated surface treatments of particles and the introduction of poisonous or harmful chemicals. In this work, we report an all-natural Pickering emulsion stabilized synergistically by starch nanocrystals and zein protein nanoparticles.

Ultra-stable Pickering emulsion stabilized by a natural particle bilayer.

Ultra-stable Pickering emulsions synergistically stabilized by zein nanoparticles and starch nanocrystals were successfully prepared and the stabilization is ascribed to the double-layer shell of binary particles. The as-prepared Pickering emulsions showed unprecedented stability against centrifugation up to 20 000g and against environmental stresses such as pH change and high temperature.
