Cytoprotective effects of hydrogen sulfide-releasing N-methyl-d-aspartate receptor antagonists mediated by intracellular sulfane sulfur

, 2014
Hydrogen sulfide (H2S) exerts a host of biological effects ranging from cytotoxicity to cytoprotection. Cytotoxicity of H2S in neurodegenerative diseases may be mediated by N-methyl-d-aspartate receptor (NMDAR) activation.

Polysulfide and persulfide-mediated activation of the PERK-eIF2α-ATF4 pathway increases Sestrin2 expression and reduces methylglyoxal toxicity

Redox Biology
Unfolded protein response (UPR) is activated in cells under endoplasmic reticulum (ER) stress. One sensor protein involved in this response is PERK, which is activated through its redox-dependent oligomerization.

Stable sulfur isotope fractionation and discrimination between the sulfur atoms of thiosulfate during oxidation by Halothiobacillus neapolitanus

, 2008
Growing cultures and nongrowing suspensions of Halothiobacillus neapolitanus selectively fractionated S-32 and S-34 during the oxidation of the sulfane- and sulfonate-sulfur atoms of thiosulfate.

Role of sulfane sulfur species in elemental tellurium nanorod formation in mammalian cells

Redox Biochemistry and Chemistry
Tellurium (Te) is an industrially useful element but its oxyanions, such as tellurite and tellurate, are naturally occurring chemical forms that can become a potential source of toxicity to humans and animals.

Preliminary exploration of polysulfide detection in wine using fluorescent probe SSP4 and A-TEEM spectroscopy

OENO One
Polysulfides have emerged as a novel class of sulfur compounds in wine that continue to be explored and characterised, but analytical challenges still remain.

Slow generation of hydrogen sulfide from sulfane sulfurs and NADH models

, 2017
Here we report the model studies of the reactions between NADH models (using HEH and BNAH) and sulfane sulfurs (using polysulfides). Such reactions could lead to the oxidation of NADH models and the production of hydrogen sulfide (H S).

Terrestrial iron sulfide minerals induce distinct regulation of intracellular redox homeostasis and iron assimilation

Ecotoxicology and Environmental Safety
Repeated exposure to airborne terrestrial natural minerals may cause pneumoconiosis and lung cancer, among which iron sulfide is identified as an aggravating factor.
