Effects of meditation on neural responses to pain: A systematic review and meta-analysis of fMRI studies.

This systematic review investigates the impact of meditation on neural responses to pain, as measured by functional magnetic resonance imaging (fMRI). Up to March 2024, we conducted searches across four databases for human studies implementing fMRI to assess the efficacy of meditation for pain relief. Eighteen studies met the inclusion criteria.

The Effectiveness of Acupuncture for Low Back Pain: An Umbrella Review and Meta-Analysis.

Recommendations on the use of acupuncture in managing low back pain (LBP) vary across different guidelines. The methodological quality of existing systematic reviews and meta-analyses on this topic also demonstrates considerable diversity, potentially leading to biased conclusions. Therefore, we comprehensively searched PubMed, EMBASE, Web of Science, Cochrane Database of Systematic Reviews, and Chinese National Knowledge Infrastructure (CNKI) databases and conducted an umbrella review.

Short bridging and partial derivatization synergistically modified β-cyclodextrin bonded chiral stationary phases for improved enantioseparation.

β-Cyclodextrin (β-CD) and its derivatives have been widely employed in the field of chiral separation, but they are still faced the limitation of low enantioselectivity and complex processes. Derivatization with functional molecules or preparation as bridging dimers are the two main modifications for β-CD to obtain chiral recognition compounds. Herein, a partially derived bridged β-CD (CPI-EBCD) bonded chiral stationary phases was prepared to improve enantioseparation.

Ruscogenin ameliorates dasatinib-induced intestinal barrier dysfunction via ErbB4/YAP and ROCK/MLC pathways.

Dasatinib is effective in the treatment of chronic and acute myeloid leukemia, which could cause the side effect of gastrointestinal bleeding by overdose or longtime use. Ruscogenin (RUS) from the traditional Chinese medicine Ophiopogon japonicas could protect endothelial microvascular barrier function. In this study, the therapeutic effect and underlying mechanisms of RUS were investigated on intestinal barrier dysfunction induced by dasatinib.

The myosin II inhibitor, blebbistatin, ameliorates pulmonary endothelial barrier dysfunction in acute lung injury induced by LPS via NMMHC IIA/Wnt5a/β-catenin pathway.

Acute lung injury (ALI) or its most advanced form, acute respiratory distress syndrome (ARDS), is a severe inflammatory pulmonary process triggered by varieties of pathophysiological factors, among which endothelial barrier disruption plays a critical role in the progression of ALI/ARDS. As an inhibitor of myosin II, blebbistatin inhibits endothelial barrier damage. This study aimed to investigate the effect of blebbistatin on lung endothelial barrier dysfunction in LPS induced acute lung injury and its potential mechanism.

Hierarchically Hybrid Porous CoO@NiMoO/CoMoO Heterostructures for High-Performance Electrochemical Energy Storage.

Hierarchical, ultrathin, and porous NiMoO@CoMoO on CoO hollow bones were successfully designed and synthesized by a hydrothermal route from the Co-precursor, followed by a KOH (potassium hydroxide) activation process. The hydrothermally synthesized CoO nanowires act as the scaffold for anchoring the NiMoO@CoMoO units but also show more compatibility with NiMoO, leading to high conductivity in the heterojunction. The intriguing morphological features endow the hierarchical CoO@NiMoO@CoMoO better electrochemical performance where the capacity of the CoO@NiMoO@CoMoO heterojunction being 272 mA·h·g at 1 A·g can be achieved with a superior retention of 84.

synthesis of FeO nanosphere/CoO nanowire-connected reduced graphene oxide hybrid networks for high-performance supercapacitors.

Three-dimensional (3D) hybrid networks consisting of reduced graphene oxide (rGO) sheets interconnected by CoO nanowires (rGO/CoO), followed by the decoration of FeO nanospheres (NSs) (rGO/CoO@FeO), were demonstrated by a facile hydrothermal method, with which the rGO/CoO networks acted as nucleation sites for the synthesis of FeO NSs. The intimate contacts between rGO, CoO NWs and FeO NSs, which result in an excellent conductive behavior, provide a unique structure with huge potential for electrochemical property promoted electrochemical supercapacitors. The rGO/CoO@FeO hybrid networks as electrodes exhibit a high capacitance of 784 F g at 1 A g with 83% retention of the initial capacitance as the current density increases from 1 to 10 A g, which is explained by the graphene-based interconnected structure owing to the advantages of accommodating the volume expansion between CoO NWs and FeO NSs.
