Silver nitrate staining of decalcified bone sections is known to reveal osteocyte canaliculi and cement lines. Nucleolar Organising Regions (NOR) are part of the nucleolus, containing argyrophilic proteins (nucleoclin/C23, nucleophosmin/B23) that can be identified by silver staining at low pH. The aim of this study was to clarify the mechanism explaining why AgNOR staining also reveals osteocyt...

OBJECTIVES To examine several poorly understood or contentious aspects of the antibacterial activity of silver (Ag(+)), including its cidality, mode of action, the prevalence of resistance amongst clinical staphylococcal isolates and the propensity for Staphylococcus aureus to develop Ag(+) resistance. METHODS The effects of Ag(+) on the viability, macromolecular synthesis and membrane integr...

Micropropagation of three genotypes of Indian mustard [Brassica juncea (L.) Czern.] using 7-days old seedling-derived transverse thin cell layer (tTCL) explants was accomplished. The genotype, explant source and addition of silver nitrate to the medium significantly influenced shoot bud induction. MS medium with 26.6 μM of 6-Benzylaminopurin (BAP) and 3.22 μM of 1-naphtaleneacetic acid (NAA) wa...
