The Reactive Sulfur Species Concept: 15 Years On [PDF]
Fifteen years ago, in 2001, the concept of “Reactive Sulfur Species” or RSS was advocated as a working hypothesis. Since then various organic as well as inorganic RSS have attracted considerable interest and stimulated many new and often unexpected ...

HIx system thermodynamic model for hydrogen production by the sulfur-iodine cycle [PDF]
The HIx ternary system (H2O – HI – I2) is the latent source of hydrogen for the Sulfur – Iodine thermo-chemical cycle. After analysis of the literature data and models, a homogeneous approach with the Peng-Robinson equation of state used for both the ...

The Inactivation of LPS Biosynthesis Genes in E. coli Cells Leads to Oxidative Stress
Impaired lipopolysaccharide biosynthesis in Gram-negative bacteria results in the “deep rough” phenotype, which is characterized by increased sensitivity of cells to various hydrophobic compounds, including antibiotics novobiocin, actinomycin D ...

Reactive oxygen species or reactive sulfur species: why we should consider the latter [PDF]
ABSTRACT The biological effects of oxidants, especially reactive oxygen species (ROS), include signaling functions (oxidative eustress), initiation of measures to reduce elevated ROS (oxidative stress), and a cascade of pathophysiological events that accompany excessive ROS (oxidative distress).

Gut microbiota reinforce host antioxidant capacity via the generation of reactive sulfur species
Summary: Gut microbiota act beyond the gastrointestinal tract to regulate the physiology of the host. However, their contribution to the antioxidant capacity of the host remains largely understudied.
