Functional epitope mapping of cell surface glucose-regulated protein 94: A combinatorial approach for therapeutic targeting.

Glucose-regulated protein 94 (GRP94) overexpression plays a critical role in tumor cell survival across various cancers. Previously, we developed K101.1, a fully human antibody targeting cell surface GRP94, which effectively inhibits tumor angiogenesis in colorectal cancer (CRC).

Zone-melting for efficient impurities removal and high-purity aluminum recovery from 7000 series computer numerical control machining scraps.

This study investigates zone melting (ZM) as an innovative method for recycling 7000 series aluminum alloy scraps, a byproduct of computer numerical control (CNC) machining in smartphone production. Traditional fluxing methods are ineffective at removing Zn, a key alloying element. Vacuum atmospheric ZM utilizes the evaporation of Zn and Mg impurities and solidification segregation to concentrate elemental impurities within the melt, facilitating their efficient removal.

Fatuamide A, a Hybrid PKS/NRPS Metallophore from a sp. Marine Cyanobacterium Collected in American Samoa.

A structurally novel metabolite, fatuamide A (), was discovered from a laboratory cultured strain of the marine cyanobacterium sp., collected from Faga'itua Bay, American Samoa. A bioassay-guided approach using NCI-H460 human lung cancer cells directed the isolation of fatuamide A, which was obtained from the most cytotoxic fraction.

Prognostic impact of one-year permanent pacemaker implantation after mitral valve surgery with the Cox-maze procedure.

Objectives: This study aimed to evaluate the prognostic impact of permanent pacemaker (PPM) implantation within the first year after mitral valve (MV) surgery combined with the Cox-maze procedure, focusing on long-term outcomes, including overall mortality, infective endocarditis (IE), and ischaemic stroke.

Methods: We conducted a retrospective cohort study using data from the National Health Insurance Service (NHIS) in South Korea, identifying 10,127 patients who underwent MV surgery with the Cox-maze procedure between 2005 and 2020. Patients were classified into the PPM and non-PPM groups based on PPM implantation within one year postoperatively.

Ligand-Shell Cooperativity in a Bilayer Silica-Sandwiched Mixed-Metals Nanocatalyst Design for Absolute Selectivity Switch.

Unlike homogeneous metal complexes, achieving absolute control over reaction selectivity in heterogeneous catalysts remains a formidable challenge due to the unguided molecular adsorption/desorption on metal-surface sites. Conventional organic surface modifiers or ligands and rigid inorganic and metal-organic porous shells are not fully effective. Here, we introduce the concept of "ligand-porous shell cooperativity" to desirably reaction selectivity in heterogeneous catalysis.
