Macrophage P2Y12 regulates iron transport and its inhibition protects against atherosclerosis.

Introduction: Iron retention is commonly observed in atherosclerotic plaques and is believed to be detrimental to atherosclerosis. Platelet P2Y12 is a target of antiplatelet therapy in preventing thrombotic complications of atherosclerosis. The protective effect of P2Y12 on hematopoiesis reported by our previous work implies the involvement of P2Y12 in iron metabolism.

White matter lesions contribute to motor and non-motor disorders in Parkinson's disease: a critical review.

Parkinson's disease (PD) is a prevalent neurodegenerative disease, characterized by movement disorders and non-motor symptoms like cognitive impairment and depression. Degeneration of dopaminergic neurons in the substantia nigra and Lewy bodies have long been considered as main neuropathological changes. However, recent magnetic resonance imaging (MRI) studies have shown that white matter lesions (WMLs) were present in PD patients.

Synthesis of the Spirocyclic Imine Fragment of Portimines Using a γ-Hydroxymethyl-αβ-butenolide Dienophile in a Diastereoselective Diels-Alder Reaction.

The synthesis of the spirocyclic imine fragment of the portimine family of marine toxins has been achieved. A densely functionalized key lactone-ester intermediate was assembled via a highly diastereoselective Diels-Alder cycloaddition, involving a novel γ-hydroxymethyl-α,β-butenolide dienophile. A Stille coupling was employed to install the vinyl group.

Phase manipulation in reflective phase gradient photonic crystals.

Phase gradient photonic crystals (PGPCs) are proposed as promising candidates for phase manipulation and can enable arbitrary electromagnetic functions, such as deflection and focusing. In stark contrast to the proposed metasurfaces, the phase variation in PGPCs arises from simple edge-configuration rather than structure resonance. Moreover, the reflection magnitude maintains a constant of 1 for the reflective case in the Bragg gap, which affords significant convenience in design.

Global trend analysis, mechanistic insights and future directions of autoimmune ear diseases: Based on comprehensive findings over the past 20 years.

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).

Adaptor protein Src-homology 2 domain containing E (SH2E) deficiency induces heart defect in zebrafish.

Adaptor proteins play crucial roles in signal transduction across diverse signaling pathways. Src-homology 2 domain-containing E (SH2E) is the adaptor protein highly expressed in vascular endothelial cells and myocardium during zebrafish embryogenesis. In this study we investigated the function and mechanisms of SH2E in cardiogenesis.

C Fullerene-Induced Reduction of Metal Ions: Synthesis of C-Metal Cluster Heterostructures with High Electrocatalytic Hydrogen-Evolution Performance.

Metal clusters, due to their small dimensions, contain a high proportion of surface atoms, thus possessing a significantly improved catalytic activity compared with their bulk counterparts and nanoparticles. Defective and modified carbon supports are effective in stabilizing metal clusters, however, the synthesis of isolated metal clusters still requires multiple steps and harsh conditions. Herein, we develop a C fullerene-driven spontaneous metal deposition process, where C serves as both a reductant and an anchor, to achieve uniform metal (Rh, Ir, Pt, Pd, Au and Ru) clusters without the need for any defects or functional groups on C.

Clinical application of phage immunoprecipitation sequencing to diagnose enterovirus D68 as the underlying etiology in a case of Gullain-Barré syndrome.

Gullain-Barré syndrome (GBS) is an acute peripheral neuropathy often preceded by respiratory or gastrointestinal infections, though molecular testing of cerebrospinal fluid (CSF) is often inconclusive. In a recent case of severe pediatric GBS in British Columbia, Canada, we detected CSF antibodies against enterovirus D (EV-D) to link GBS with prior EV-D68 respiratory infection.

Downregulation of interleukin 11 regulates the transforming growth factor-β/ERK1/2 signaling pathway to inhibit articular capsule fibrosis and alleviate post-traumatic articular capsule contracture.

Background: Post-traumatic capsular contracture is a common complication of joint injury and surgery. Post-traumatic capsular contracture is associated with fibrosis characterized by excessive differentiation and proliferation of myofibroblasts and abnormal secretion and accumulation of extracellular matrix. Previous studies have suggested that interleukin 11 (IL11) plays a role in myocardial fibrosis.
