本研究系统性揭示贝莱斯芽孢杆菌（B. velezensis）通过破坏细胞膜完整性（致MDA升高）、诱导活性氧（H2O2/O2•-）积累及抑制抗 ...

推荐 为解决火龙果采后易腐烂变质、货架期短的问题，研究人员开展了纳米氢水（HW）处理对火龙果品质及抗氧化系统影响的研究。结果表明，HW处理显著降低腐烂指数、延缓可溶性固形物含量下降，维持果实色泽和质地，并通过抑制H2O2和O2-积累、增强SOD和CAT ...

Nascimur uno modo, multis morimu ('in one way we are born, in many ways we die'), and there is probably no single way to age. Indeed, so far there is no single accepted explanation or mechanism of ...

image: PVDC undergoes dehalogenation in the presence of KOH, removing Cl and H functional groups to generate the clean byproducts KCl and H2O. The dehalogenated carbon sites exhibit very high ...

Normal aerobic metabolism (via processes such as photosynthetic and respiratory electron transport chains) in plants yields varied reactive oxygen species (ROS) such as singlet oxygen (1O2), ...

Reactive oxygen species (ROS), in moderate amounts, play an essential role in regulating different physiological functions in organisms. However, increased amounts of ROS may cause oxidative stress ...
