International Endodontic Journal, EarlyView.ABSTRACT Aim The aim was to characterize the taxonomic and functional composition of the microbiome involved in primary endodontic infections and to evaluate their association with the periapical lesion size using shotgun metagenomic sequencing. Methodology Samples from primary root canal infections diagnosed with apical periodontitis were analysed ...

International Endodontic Journal, EarlyView.ABSTRACT Aim To characterize the intracanal microbiota and identify key microbial taxa and functional pathways associated with regenerative endodontic treatment (RET) outcomes. Methodology In this observational cohort study, 196 samples were collected at five time points from external tooth surfaces (T1, T4) and root canals (T2, T3, T5).

Nitrogen dioxide absorption into sulfite inhibited by thiosulfate [PDF]
, 2019 Emulsified sulfur was found to be the most suitable form of sulfur for in-situ thiosulfate production for sulfite inhibition with a maximum sulfur-to-thiosulfate-conversion of 50 % and t₅₀ of 6 hours. Increasing the ionic strength of the solution reduces

Oxidation of Thiosulfate with Oxygen Using Copper (II) as a Catalyst
Metals, 2019 Thiosulfate effluents are generated in the photography and radiography industrial sectors, and in a plant in which thiosulfates are used to recover the gold and silver contained in ores.

Thiosulfate Reduction in Halanaerobium: A Genomic and Physiological Investigation [PDF]
, 2017 Bacteria that produce sulfide have been investigated for their role in corrosion of steel surfaces. Attention has mainly focused on bacteria able to reduce sulfate to sulfide (SRB). However, bacteria that produce sulfide by reducing thiosulfate (TRB) but

Free sulfurous acid (FSA) inhibition of biological thiosulfate reduction (BTR) in the sulfur cycle-driven wastewater treatment process [PDF]
, 2017 A sulfur cycle-based bioprocess for co-treatment of wet flue gas desulfurization (WFGD) wastes with freshwater sewage has been developed. In this process the removal of organic carbon is mainly associated with biological sulfate or sulfite reduction ...

Separation of Ag and Cu from Their Aqueous Thiosulfate Complexes by UV-C Irradiation
Metals, 2019 In recent years, there has been renewed interest in the use of thiosulfate as a substitute for cyanide in silver leaching. Copper thiosulfate leaching without ammonia was applied to extract silver from silver sulfide, resulting in the production of Ag ...
