Advanced Science, EarlyView.An adhesive hydrogel depot with polyphenol‐armored nanogenes is developed for treating aged osteoarthritis. This system maintains miR‐140 bioactivity, prolongs its intra‐articular retention, and enhances transfection into chondrocytes, leading to the downregulation of senescence‐associated pathways.

The Production of Caramel with the DPPH Radical Scavenging Activity.
NIPPON SHOKUHIN KAGAKU KOGAKU KAISHI, 1999 単糖類を塩基性化合物の存在下でカラメル化反応を行い,強いDPPHラジカル捕捉能を有するカラメルを得た.(1) ペントース,ヘキソースは塩基性化合物の存在下で強いDPPHラジカル捕捉能を有するカラメルとなるが,スクロース,ソルビトールのカラメルは,ほとんどDPPHラジカル捕捉能を示さなかった.(2) カラメルの色価,DPPHラジカル捕捉能及びカラメル調製時の作業性,食品への利用性から,カラメル化助剤としてはクエン酸ナトリウム,カラメル化温度は130℃が適当であった.(3) カラメル中の非透析物含量は約75%,透析物は約25%であり,カラメルの着色度,還元力,DPPHラジカル捕捉能の主体は非透析物に依存していた.

Advanced Science, EarlyView.ABSTRACT Infected diabetic wounds are sustained by a vicious cycle of hyperglycemia‐driven bacterial infection, persistent oxidative stress, and excessive inflammation, which collectively disrupt the ordered progression of tissue repair. Here, we engineered a stage‐adaptive Janus microneedle patch (MN‐FeSAC‐PPE) to enable a staged therapeutic process ...
