Article Synopsis
- CO electrochemistry is a promising reaction for energy storage but faces challenges like low efficiency and poor reversibility in Li-CO batteries.
- First-principles calculations were used to study 21 dual-atom catalysts, revealing that MoMoNC has the best interaction with CO due to its favorable electronic properties.
- The findings suggest that MoMoNC can lower the energy barrier for the Li-CO discharging process, improving the performance of Li-CO batteries and guiding future catalyst design.
To compare the efficacy and safety of the localization of small pulmonary nodules (sPNs) with dyed medical glue (DMG) and hookwires prior to video-assisted thoracoscopic surgery (VATS). A total of 344 patients were enrolled in this single-center retrospective cohort study between January 2018 and May 2022. There were 184 patients who underwent localization with DMG.

- * Researchers introduced aggregation-induced emission luminogens embedded nanospheres (AIENPs) that emit red light and are used as signal amplifiers in LFIA for the detection of zearalenone (ZEN).
- * The AIENP-LFIA outperformed the traditional time-resolved dye-embedded nanoparticles (TRNPs) by showing stronger photoluminescence and better sensitivity, achieving lower detection limits and improved accuracy for ZEN quantitation in corn samples.
Homogenization of electric field distribution facilitating the Zn anode reversibility.
Chem Commun (Camb)
December 2022
The surface morphology of the zinc-metal electrode was modulated using different levels of physical polishing treatment. Modulating the surface scratches homogenized the deposition electric field and reduced the local current density. A reasonable surface treatment could limit the "tip effect" and bring homogeneous plating and stripping of the Zn electrode.

Herein, an anti-SEA monoclonal antibody (anti-SEA mAb) was prepared by injecting the SEA protein in BALB/c mice, and a novel immunochromatographic assay (ICA) was developed for the rapid and sensitive determination of SEA in pasteurized milk by using highly luminescent quantum dot beads (QB) as signal amplification probe. Given the 1020-fold enhancement in the photoluminescence intensity of QB to the original quantum dot, the proposed QB-ICA exhibits high sensitivity for SEA determination in real milk samples with a limit of detection of 1.

Article Synopsis
- The study investigates how the CD11b agonist leukadherin-1 (LA1) affects the activation of dendritic cells by Toll-like receptors 7 and 9 in mice.* -
- Using various assays, it was found that LA1 can inhibit the expression of specific surface markers and cytokine release triggered by TLR7 and TLR9 agonists.* -
- The mechanism behind this effect involves the blockade of the NF-κB p65 signaling pathway, suggesting that LA1 might hinder immune responses mediated by these receptors.*
Objective: Myoclonus induced by etomidate during induction of general anesthesia is a common phenomenon. This prospective, randomized, saline-controlled clinical study was performed to evaluate the effect of parecoxib sodium pretreatment on the incidence and severity of etomidate-induced myoclonus.
Methods: 60 patients, American Society of Anesthesiologists (ASA) physical status I or II, aged 20 to 60 years, who were scheduled to undergo elective laparoscopic cholecystectomy under general anesthesia, were allocated randomly into one of two groups to receive parecoxib sodium 40 mg intravenous (group P, n = 30) or the same volume of saline (group S, n = 30) 30 minutes before administration of etomidate (0.
Objective: Postoperative pain is a common phenomenon after pediatric tonsillectomy. This prospective randomized double-blind placebo-controlled clinical trial was performed to evaluate the analgesic efficacy of intravenous parecoxib sodium in children undergoing tonsillectomy.
Methods: Sixty children (American Society of Anesthesiologists physical status I-III, aged three to seven years, and scheduled to undergo elective tonsillectomy under general anesthesia) were randomly allocated into one of two groups to receive intravenous parecoxib sodium 1 mg·kg(-1) (Group P, n = 30) or the same volume of saline (Group S, n = 30) just after induction of general anesthesia.
Background: Psychological issue is the most common co-morbidity of women with breast cancer (BC) after receiving treatment. Effective coping with this problem is significant importance. The aim of this meta-analysis is to evaluate the benefits of mindfulness-based stress reduction (MBSR) on psychological distress among breast cancer survivors.
View Article and Find Full Text PDFBackground: Postoperative shivering is one of the most common complications in patients recovering from general anaesthesia. Although a variety of pharmacological therapies have been used to control postoperative shivering, no ideal drug has been found to date.
Objectives: The aim of this study was to compare the efficacy and accompanying side-effects of prophylactic parecoxib sodium with that of tramadol or placebo for the prevention of postoperative shivering.
