Effects of epidural esketamine versus sufentanil on labor analgesia and postpartum depression: a retrospective cohort study.

Objective: There is a lack of research on epidural esketamine for labor analgesia. The purpose of this research is to compare the efficacy of epidural esketamine and sufentanil on labor analgesia and postpartum depression.

Methods: A total of 187 cephalic full-term parturients with single-fetus vaginal delivery were collected in this retrospective study from Jan 2022 to Jan 2023.

Facile preparation of a hydrophilic Eu-based ratiometric fluorescent nanosensor for Cu ion detection and imaging in living cells.

In this work, a hydrophilic Eu-based ratiometric fluorescent nanosensor (PAAC-Eu) was developed for Cu ion detection in aqueous solutions and imaging in living cells. The sensor was prepared a simple one-step reaction at room temperature, leveraging the synergistic coordination of commercially accessible polyacrylic acid (PAA) and coumarin-3-carboxylic acid (CCAH) with Eu ions. PAAC-Eu was easy to disperse in aqueous media and exhibited two characteristic emission bands at 406 nm and 618 nm, respectively, upon excitation at 350 nm.

Predictive value of neutrophil-to-lymphocyte ratio on admission for intrapartum maternal fever in parturients undergoing epidural analgesia: A retrospective cohort study using propensity score-matched analysis.

Objective: To identify the predictive value of the neutrophil-to-lymphocyte ratio (NLR) on admission for intrapartum maternal fever in parturients undergoing epidural analgesia (EA).

Methods: In this retrospective cohort study, propensity score matching (PSM) was applied to address covariates. Univariate and multivariate regression analyses were implemented in sequence to find out the factors influencing intrapartum fever.

Phosphorescence enhancement of pyridinium macrocycles by poly(vinylalcohol).

A phosphorescence enhancement of pyridinium macrocycle/monomer phosphors is realized with up to 14.7-fold prolonging of the phosphorescence lifetimes and visible afterglow by doping into a poly(vinylalcohol) (PVA) matrix. The abundant hydrogen-bonding interactions and electrostatic interactions between the phosphors and the PVA suppressed the nonradiative decay processes, slowed down the radiative decay and nonradiative decay of triplet states, and therefore promoted the long-lived RTP.

Thickness-Independent Energy Dissipation in Graphene Electronics.

The energy dissipation issue has become one of the greatest challenges of the modern electronic industry. Incorporating graphene into the electronic devices has been widely accepted as a promising approach to solve this issue, due to its superior carrier mobility and thermal conductivity. Here, using Raman spectroscopy and infrared thermal microscopy, we identify the energy dissipation behavior of graphene device with different thicknesses.
