Development of an anti-oxidative intraocular irrigating solution based on reactive persulfides
Scientific Reports, 2022 Anti-oxidative intraocular irrigating solutions (IISs) based on reactive persulfides, such as oxidized glutathione disulfide (GSSG), are commonly used worldwide. However, even with GSSG-based IISs, it has been shown that oxidative stress can occur during

Persulfides and the cellular thiol landscape [PDF]
Proceedings of the National Academy of Sciences, 2014 The biochemistry of sulfur touches on every aspect of cellular biology, from protein structure and function to redox regulation to defense against chemical stress. Over the last decade, posttranslational modification of protein thiols by reactive oxygen or nitrogen species has emerged as a major component of signal transduction, leading to both ...

Sulfane Sulfur Compounds as Source of Reappearance of Reductive Off-Odors in Wine
Fermentation, 2022 Reactive compounds with one or more sulfane sulfur atoms can be an important source of reductive off-odors in wine. These substances contain labile sulfur, which can participate in microbiological (enzymatic) and chemical transformations (including in ...

Regulation, sensory domains and roles of two Desulfovibrio desulfuricans ATCC27774 Crp family transcription factors, HcpR1 and HcpR2, in response to nitrosative stress [PDF]
, 2016 In silico analyses identified a Crp/Fnr family transcription factor (HcpR) in sulfate-reducing bacteria that controls expression of the hcp gene, which encodes the hybrid cluster protein and contributes to nitrosative stress responses.
