A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Deciphering the catalytic and pharmacological mechanisms of Coptis chinensis herbzymes to renovate intestinal microenvironment for colitis alleviation

BMEMat, EarlyView.
The synthesized CCzymes possess both antioxidant enzyme activity and pharmacological properties inherent to Coptis chinensis. By their antioxidant enzyme activity, CCzymes can attenuate oxidative stress within the inflammatory region of ulcerative colitis (UC), while their pharmacological activity acts on macrophage polarization and the intestinal ...

Nano‐networks via reaction‐induced self‐assembly coordinate spatiotemporal multi‐drug delivery for acute kidney injury therapy

BMEMat, EarlyView.
Multifunctional nano‐networks (NNWs) are prepared via reaction‐induced self‐assembly (RISA) of spermidine (SPD), epigallocatechin gallate (EGCG), 2‐formylphenylboronic acid (2‐FPBA), and deferoxamine (DFO) through dynamic iminoboronate bonds. These NNWs leverage the oxidative AKI microenvironment to trigger disintegration, enabling site‐specific ...

2D copper nanozyme patches facilitate bone regeneration via interfacial modulation of osteoclast‐osteoblast dynamics

BMEMat, EarlyView.
This study develops a nano‐enzyme patch (ezPatch) targeting bone interfaces. Utilizing ligand‐to‐metal charge transfer (LMCT) catalysis and bone‐targeting ligands on copper nanosheets, ezPatch simultaneously scavenges reactive oxygen species (ROS) and generates oxygen in situ at bone‐losing sites.

Impact of storage time and solvent type on 2,2-diphenyl-1-picrylhydrazyl free radical stability

Case Studies in Chemical and Environmental Engineering
The effect of storage time and solvent on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical stability was studied using electron spin resonance. Tetrahydrofuran affected the g-factor due to a rearrangement within the DPPH structure that changed the radical ...

Optical evaluation of antioxidant activity: A comparison between a spectrophotometer and a homebuilt photometer [PDF]

E3S Web of Conferences
The antioxidant activity of an orange peel extract is determined using a DPPH (2,2-diphenyl-1-picrylhydrazyl) solution. Sample absorption is measured with both a commercial spectrophotometer and a homebuilt photometer equipped with a 525-nm LED.
