Effectiveness and safety of acupuncture for melasma: A meta-analysis of randomized controlled trials.

Background: Treating melasma remains challenging. We conducted a meta-analysis to assess the effectiveness and safety of acupuncture as a treatment option.

Methods: We searched three English and four Chinese databases up to January 2, 2024.

Microseparation of Lipophilic and Hydrophilic Metabolites for Single Oocyte Mass Spectrometry Analysis.

Single-cell metabolic analysis has not yet achieved the coverage of bulk analysis due to the diversity of cellular metabolites and the ionization competition among species. Direct ionization methods without separation lead to the masking of low-intensity species. By designing a capillary column emitter and introducing reverse-phase chromatography principles, we achieved the microseparation of lipophilic and hydrophilic metabolites and lowered the limit of detection of hydrophilic metabolites to the level of a single oocyte.

Preparation of a biodegradable packaging film by konjac glucomannan/sodium alginate reinforced with nitrogen-doped carbon quantum dots from crayfish shell for crayfish meat preservation.

The development of biomass material is an important approach to alleviating the excessive using of plastic packaging, by which the product could be more environmentally friendly and lower toxicity. In this study, we developed a biodegradable photodynamic antibacterial food packaging film using nitrogen-doped carbon quantum dots (N-CQDs) synthesized from crayfish shells, combined with konjac glucomannan (KGM) and sodium alginate (SA). Casting method was used to prepare the composite film and results indicated that incorporation of N-CQDs significantly enhanced the mechanical and barrier properties of the film by reducing the number of micropores.

Antioxidant taurine inhibits chondrocyte ferroptosis through upregulation of OGT/Gpx4 signaling in osteoarthritis induced by anterior cruciate ligament transection.

Objective: The aim of this study was to investigate the potential molecular mechanisms by which taurine protects against cartilage degeneration.

Methods: The anterior cruciate ligament transection (ACLT) surgery was used to construct an animal model of osteoarthritis (OA). Metabolomics was used to identify characteristic metabolites in osteoarthritic chondrocytes.

Insights into the MOF-Based Classic Configuration for the Differences in Effective Dye Adsorption, Magnetic Properties, and Computational Analyses.

Two 3D/2D anionic metal-organic frameworks (MOFs), [Cu(HL)] () and [Mn(L)(DMF)] ( (DMF = ,-dimethylformamide), were synthesized by the solvothermal reaction of metal salts and 5'-(4-carboxyphenyl)-2',4',6'-triethyl-[1,1':3',1″-terphenyl]-4,4″-dicarboxylic acid (HL). Single-crystal X-ray diffraction analyses revealed that complex shows three-dimensional (3D) frameworks with a (3,6)-connected 3-fold interpenetrated topology with the Schläfli symbols of {4.6}{4.
