A method of in situ preformed auto-alloplastic replacement for the treatment of long femoro-poplitela vascular obstructions is described on the basis of highly promising experimental results. A macropouous tube made of aplastic net and obturated with a silicone rubber mandril was implanted next to the obstructed vascular section. The two ends of the live auto-alloplastic tube formed in situ around the mandril were joined in a second operation to the femoral and popliteal arteries. Early experience is described on grounds of four cases, together with the current and possible future indications of the operation.

In this study, we developed a facile one-pot synthesis of a nanocomposite consisting of silver nanoparticles (AgNPs) growing over graphene oxide (GO) nanoflakes (AgNPs@GO). The process consists of the in situ formation of AgNPs in the presence of GO nanosheets via the spontaneous decomposition of silver(I) acetylacetonate (Ag(acac)) after dissolution in water. This protocol is compared to an ex situ approach where AgNPs are added to a waterborne GO nanosheet suspension to account for any attractive interaction between preformed nanomaterials.

The synthesis of degradable polymer prodrug nanoparticles is still a challenge to be met, which would make it possible to remedy both the shortcomings of traditional formulation of preformed polymers (, low nanoparticle concentrations) and those of the physical encapsulation of drugs (, burst release and poor drug loadings). Herein, through the combination of radical ring-opening polymerization (rROP) and polymerization-induced self-assembly (PISA) under appropriate experimental conditions, we report the successful preparation of high-solid content, degradable polymer prodrug nanoparticles, exhibiting multiple drug moieties covalently linked to a degradable vinyl copolymer backbone. Such a rROPISA process relied on the chain extension of a biocompatible poly(ethylene glycol)-based solvophilic block with a mixture of lauryl methacrylate (LMA), cyclic ketene acetal (CKA) and drug-bearing methacrylic esters by reversible addition fragmentation chain transfer (RAFT) copolymerization at 20 wt% solid content.

Considerable fundamental understanding of aryne reactivity has resulted from this body of research. The multi-yne cycloisomerization substrate is typically pre-formed and the (rate-limiting) closure of this diyne/diynophile pair to produce the isomeric benzyne generally requires thermal input, often requiring reaction temperatures of >100 °C and times of 16-48 h to achieve near-full conversion.

Controlled high-order clustering of cell-surface proteins is an essential but unmatched regulatory mechanism in living systems for the modulation of cell behavior. Here, we present a strategy for generating extended and tunable one-dimensional clusters of death receptors on live cell surfaces by employing synthetic peptides to noncovalently bridging the proteins. The on-cell assembly process is validated through super-resolution fluorescence imaging and fluorescence lifetime imaging analyses.

Miniature spectrometer is powerful tool for scientific research and industrial inspection. Here, we report the fabrication of graded perovskite filters with tunable bandgap and their application in constructing miniature spectrometer. The graded perovskite filters were fabricated using a Finkelstein reaction between formed halogen ion with a preformed MAPbX film.
