Coordination of inorganic disulfide species to ferric N-acetyl microperoxidase 11.
Biochem Biophys Res Commun
January 2025
The interest in chemical interactions between inorganic sulfur species and heme compounds has grown significantly in recent years due to their physiological relevance. The model system ferric N-acetyl microperoxidase 11 (NAcMP11Fe) enables the exploration of the mechanistic aspects of the interaction between the ferric heme group and binding sulfur ligands, without the constraints imposed by a protein matrix and the stabilizing effects of distal amino acids. In this study, we investigated the coordination of disulfane (HSSH) and its conjugate base hydrodisulfide (HSS) to NAcMP11Fe.

- Perioperative visual loss is a rare but serious complication that can occur after nonocular surgeries, and recent studies have identified various factors that may lead to this issue.
- A case is presented involving a 47-year-old woman who experienced visual loss after a pterional craniotomy for a brain tumor, revealing postoperative symptoms such as third cranial nerve palsy and persistent vision problems lasting over three months.
- The authors emphasize the importance of considering orbital compartment syndrome in neurosurgical patients with vision loss and recommend a multidisciplinary approach to help prevent such complications.
Background: Following California's statewide law prohibiting the sale of flavoured tobacco products, some cigarette brands introduced new variants advertised as non-menthol, yet featuring design and text commonly found in menthol cigarette marketing.
Methods: Data are from the February-May 2023 wave of the Tobacco Epidemic Evaluation Network (TEEN+) national probability-based survey (aged 13-25 years). Respondents (N=10 217) were shown images of two (of four) 'new non-menthol' brand ads or packaging and two comparators ('classic' non-menthol and menthol cigarette brands).
