Assessing Ryanodine Receptor Inhibition and Antioxidant Ability of Carvedilol and its Abilities

, 2016
The antioxidant ability of the commonly prescribed antiarrhythmic medication carvedilol was assessed using two distinct assays. The first assay monitored the depletion of the stable radical DPPH via hydrogen atom abstraction utilizing UV-VIS spectrophotometry.

In vivo Antioxidative Ability of Enzymatic Hydrolysates from Zein.

NIPPON SHOKUHIN KAGAKU KOGAKU KAISHI, 2000
本研究では,脱アミドゼインを1%アンモニアを含む8Mの尿素で変性した後,粗製な市販タンパク質分解酵素であるプロレザーで加水分解し,得られた酵素加水分解産物に生体内の過酸化脂質の生成を抑制する作用があるかどうかを明らかにすることを目的として研究を行い,以下の結果を得た.1) 脱アミドゼイン酵素加水分解産物群の生体内過酸化脂質量はそれと同じ組成のアミノ酸混合物食群より有意に低値が認められたことから,生体内で過酸化脂質の生成を抑制する原因はアミノ酸ではないと考えられた.2) 脱アミドゼイン群の生体内過酸化脂質量はその酵素加水分解産物群より有意に高値が認められたことから,生体内過酸化脂質の生成抑制は脱アミドゼインより酵素分解で生じたペプチドの作用であると考えられた.

4D‐Printable Poly(Thio)urethane Photoresins With Reactive Oxygen Species Responsiveness and Anti‐Inflammatory Functionality

Advanced Functional Materials, EarlyView.
This work introduces UV‐curable poly(thio)urethane (PSU) thermosets as 4D printable scaffolds responsive to oxidative stress. PSU networks with 100 wt.% polypropylene glycol (PPG) effectively suppress inflammatory markers in microglial cells to basal values.

Elucidating the Role of Surface Ligands on the Oxidative Etching of Au Bipyramids During Photothermia Using Liquid Cell Transmission Electron Microscopy

Advanced Functional Materials, EarlyView.
Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...
