Construction of an Interfacial Layer of Aramid Fibers Grafted with Glycidyl POSS Assisted by Heat Treatment and Evaluation of Interfacial Adhesion Properties with Epoxy Resin.

The surface of para-aramid fibers (AFs) was modified via air-assisted heat pretreatment and solution impregnation by varying the glycidyl polyhedral oligomeric silsesquioxane (POSS) content. Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy showed an ester group, confirming the graft reaction between glycidyl POSS and oxidized AFs. The mechanical properties of AFs could be altered by varying the glycidyl POSS content.

HMGA2 Synergizes with EZH2 to Mediate Epithelial Cell Inflammation and Apoptosis in Septic Lung Dysfunction.

Objective: High mobility group AT-hook 2 (HMGA2) has been increasingly acknowledged to be significantly expressed in malignant tumors. However, it has been discovered to serve as a pro-inflammatory factor in several diseases. This study aimed to investigate the involvement of HMGA2 in septic lung injury.

Highly stable folic acid functionalized copper-nanocluster/silica nanoparticles for selective targeting of cancer cells.

In this paper, we present a novel strategy to construct folic acid functionalized conjugated Cu nanoclusters (CuNCs) and silica (SiO) nanocomposites for targeted detection of cancer cells. First of all, BSA capped CuNCs were encapsulated into a SiO matrix. The resulting CuNCs@SiO nanoparticles showed bright red fluorescence with an enhanced photoluminescence quantum yield compared with free CuNCs, as well as improved stability in a complex biological environment owning to the protection of the SiO matrix.
