Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α-diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e.

Epstein-Barr nuclear antigen 1 (EBNA1), a sequence-specific DNA binding protein of Epstein-Barr virus (EBV), is essential for viral genome replication and maintenance and is therefore an attractive target for the therapeutic intervention of EBV-associated cancers. Several EBNA1-specific inhibitors have demonstrated the ability to block EBNA1 function in vitro, but practical delivery strategies for these inhibitors in vivo are still lacking. Here, we report an intelligent hierarchical targeting theranostic nanosystem (denoted as mZGOCS@MnO-P5) that integrates an azide (N3) terminal dual-targeting peptide (N3-P5), a tumor microenvironment-responsive degradable MnO nanosheet, and a mesoporous ZnGaO:Cr, Sn near-infrared persistent luminescence (NIR-PL) nanosphere (mZGOCS).

Background: Non-invasive brain stimulation (NIBS) techniques, such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), may offer an alternative treatment strategy for impulsive behaviour. By modulating brain activity, these techniques could potentially enhance impulse control and mitigate impulsivity.

Aims: To provide a comprehensive analysis of the correlation between NIBS parameters, targeted brain regions and impulsivity.

Purpose: Tissue engineering aims to recreate natural cellular environments to facilitate tissue regeneration. Gelatin methacrylate (GelMA) is widely utilized for its biocompatibility, ability to support cell adhesion and proliferation, and adjustable mechanical characteristics. This study developed a GelMA and graphene bioink platform at concentrations of 1, 1.

Article Synopsis
  • Persistent luminescence (PersL) materials are beneficial for bio-imaging in the near-infrared (NIR-I) and shortwave-infrared (SWIR-II) regions, providing clearer images without background interference.
  • The newly developed material, ZnGaNiCrSnO (ZGSO:Cr, Ni), emits light in both the deep-red/NIR-I and SWIR (NIR-II) ranges and can be excited by various light sources, enabling it to function in dual biological imaging windows.
  • Preliminary experiments demonstrate that ZGSO:Cr, Ni allows for high-resolution and depth-sensitive imaging, suggesting significant potential for accurate biological analysis and tracing applications.
