This study develops a cartilage‐targeted DNA origami system (OCS) that protects and delivers si‐Stat3 to chondrocytes. OCS reduces MMP13 expression, enhances extracellular matrix stability, and lowers oxidative stress while improving cell survival. In vivo, OCS decreases cartilage degradation biomarkers and promotes tissue repair factors, demonstrating

Improved ultraviolet spectrophotometry of serum theophylline.
Abstract We present an improved method for ultraviolet spectrophotometry of theophylline in serum. We studied various extraction techniques aimed at eliminating interferences from co-extractable serum constituents. In the resulting modified procedure, 1 ml of serum is required and a salt-solvent pair of ammonium sulfate and chloroform ...

This work provides a novel molecular design strategy to develop three naphthoquinone‐derived cathodes (NQ1, NQ2, and NQ3) by linking one, two, and three amido‐naphthoquinone redox centers onto a benzene ring in a convenient way. Structure evolution to increased hydrogenbonds and molecular size enables high performance LOBs by joint solubility suppress ...

The authors report on the significant impact of the spin‐coated Cr2O3 interface layer on the electrical properties and performance characteristics of Au/undoped‐InP (Au/InP) Schottky diodes (SD). The results and approach convincingly demonstrate the potential application of the Cr2O3 interfacial layer in delivering enhanced performance and contributing

Applied ultraviolet spectrophotometry of fats and oils [PDF]
The chemist has in the spectrophotometric method a rapid and simple means of studying changes in the double bond systems of fatty acids. The method is highly sensitive. It has found application in studies of processing of oils, improvement of drying oils, catalytic hydrogenation, routine analytical work, soap and tallow control, as well as in nutrition

A self‐assembling, aggregation‐enhanced tetrahedral DNA nanostructure (tFNA), termed TACs, enables localized accumulation and sustained release of ceftriaxone while co‐delivering antisense oligonucleotides that silence mecA, reduce PBP2a expression, and restore β‐lactam susceptibility in MRSA.
