Giant Five-Shell Polyoxometalate Cages and the Single-Cluster-Based Nanowire Superstructures.

The preparation of polyoxometalate molecular cages has always been a long-term and challenging pursuit. In this work, we have successfully prepared two unprecedented giant heterogeneous POM-based purely inorganic molecular cages with symmetry, which contain the aggregation of M (M = Ni, Co)-substituted trilacunary {PW} and Mn-bridged {W}. Sodium ions are used as templates to fill the cages.

Dihydromyricetin ameliorates hyperuricemia through inhibiting uric acid reabsorption.

Background: Hyperuricemia (HUA) is a chronic disease caused by abnormal purine metabolism with high prevalence. Dihydromyricetin (DMY) is a natural flavonoid that is abundant in plants, such as vine tea, grapes and bayberry. DMY has been shown to possess multiple biological properties, but its anti-HUA effect remains underexplored.

Progress of Research and Comparative Analysis on the Combination of Mast Cell Stabilizers and Antihistamines in Allergic Conjunctivitis Treatment.

Allergic conjunctivitis (AC) is a common ophthalmological condition primarily associated with type I and IV allergic responses. Although AC typically does not cause visual impairments, it can significantly reduce the quality of life of individuals, regardless of age, with severe cases possibly affecting the cornea and potentially impairing vision. However, the mechanisms of action of primary therapeutic drugs-antihistamines, mast cell stabilizers, and their combination-remain unclear.

Enhanced-electrochemiluminescence biosensor for detecting miRNA-21 based on a CuO-mediated click reaction and catalytic hairpin self-assembly.

MicroRNAs (miRNAs) are closely associated with cancer and have been considered cancer biomarkers. Herein, we propose an electrochemiluminescence (ECL) biosensor for detecting miRNA-21 based on target-induced catalytic hairpin self-assembly (CHA) and CuO-mediated azide-alkyne cycloaddition. Two hairpin DNAs were employed: one was immobilized on magnetic beads (HP2) and another was labeled with CuO (HP1-CuO).

Immunotherapy combined with antiangiogenic therapy as third- or further-line therapy for stage IV non-small cell lung cancer patients with ECOG performance status 2: A retrospective study.

Background: Patients with Eastern Cooperative Oncology Group performance status (ECOG PS) 2 probably cannot tolerate chemotherapy or other antitumor therapies. Some studies have reported that immunotherapy combined with antiangiogenic therapy is well-tolerated and shows good antitumor activity. However, the efficacy of this combination as a later-line therapy in patients with ECOG PS 2 is unclear.

Rational Conversion of Imine Linkages to Amide Linkages in Covalent Organic Frameworks for Photocatalytic Oxidation with Enhanced Photostability.

Covalent organic frameworks (COFs) and their applications in photocatalysis have been extensively studied, but the instability of imine-linked COFs is an important factor limiting their performance. In this work, two imine-linked COFs were successfully converted to amide-linked COFs through post synthetic modification (PSM). The oxidized COFs presented lower binding energy to O, exhibited higher photocatalytic activity for oxidation of thioethers and coupling of benzylamines with excellent stability.

Recent advances in emerging application of functional materials in sample pretreatment methods for liquid chromatography-mass spectrometry analysis of plant growth regulators: A mini-review.

Plant growth regulators (PGRs) are a class of small molecular compounds, which can remarkably affect the physiological process of plants. The complex plant matrix along with a wide polarity range and unstable chemical properties of PGRs hinder their trace analysis. In order to obtain a reliable and accurate result, a sample pretreatment process must be carried out, including eliminating the interference of the matrix effect and pre-concentrating the analytes.

Anti-hyperuricemia effect of hesperetin is mediated by inhibiting the activity of xanthine oxidase and promoting excretion of uric acid.
