Synergistically activated dual-locked fluorescent probes to monitor H₂S-induced DNA damage

Abstract

NAN0-N3 and NAN6-N3 could monitor DNA damage induced by the overexpression of H2S.

Chameleon-like Anammox Bacteria for Surface Color Change after Suffering Starvation

“…This suggests that they have self-protection strategies that researchers have not fully recognized. Previous studies have shown that H 2 S stimulates the production of reactive oxygen species (ROS) and decreases glutathione levels in bacteria, resulting in lipid peroxidation and DNA damage, , and this inhibitory effect could not be relieved.…”

“…Importantly, H 2 S can activate the bacterial oxidative response, protect cells from oxidative damage, and increase resistance to antibiotics . On the other hand, H 2 S at high concentrations seriously stimulates reactive oxygen species (ROS) production and inhibits microbial activity after long-term exposure . When H 2 S is produced in large amounts, it is often accompanied by bacterial disintegration, death, and decay of the whole consortia …”

Mixed-valence compounds based on heterometallic-oxo-clusters containing Sb(iii,v): crystal structures and proton conduction

“…The structures were solved using direct methods and refined with fullmatrix least-squares on F 2 using the SHELX-2018 program package. 31 In compound 2, Cd(5) co-occupies the same site with Co(5), while Cd(6) co-occupies the same site with Co (6). We validated the empirical formulae with results from elemental analysis, thermogravimetric analysis, energy-dispersive spectroscopy analysis and X-ray photoelectron spectroscopy analysis (Fig.…”

“…In recent years, metal-oxo-cluster based compounds with unique molecular structures have been widely studied due to their potential applications in magnetism, catalysis, biomedicine, proton conduction, etc. [1][2][3][4][5][6][7][8][9][10] The Sb(III) ion with an ns 2 configuration has stereochemically active lone pair electrons in the s orbitals, making it important in many optoelectronic fields such as ferroelectricity and nonlinear optics. 11,12 The Sb (III) ion can interact with the O 2− ion in various coordination modes, such as [SbO 3 ], [SbO 4 ], and [SbO 5 ], which can further combine with other metal ions to form heterometallic oxocluster based compounds in various structural types.…”
