Research ArticleOpen accessIn the keywordsConstruction of Recombinant Bioleaching Bacteria Thiobacillus ferrooxidans with Fluoride-Resistant ActivityYun-Chang Cao, Hong-Bo Wen, Nan Hu et al.Thiobacillus ferrooxidans is an important bioleaching bacterium, widely used in leaching, recovery of low-grade metals and environmental bioremediation. In bio-metallurgy industry, fluoride existing in some hard rock uranium deposits in south China severely affects the bacteria viability and inhibit leaching reproduction. In this study, the flr-4 gene that has strong resistance to fluorine ion in Caenorhabditis elegans, was cloned into … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 23 May 2018 · 11,341 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparative Analysis of Surface Microhardness and Antimicrobial Activity of Conventional and Bioactive Composite Materials for Dental RestorationsBruno Fongaro Dalbosco, Rafael da Silva Vanolli, Poliana Maria de Faveri Cardoso et al.This study evaluated the fluoride release capability, antimicrobial activity, and surface microhardness of bioactive composite resins, critical properties for the effectiveness and durability of dental materials in restorative procedures. Conventional and bioactive composite resins with varying viscosities were tested. Specimens of each resin type were prepared and stored in physiological saline solution for 24 hours to simulate oral conditions. Surface … …Current Research in Dentistry, Vol. 16, Issue 1 · 29 Jan 2026 · 2,809 accessesView PDF Cite
