The bond strengths of a silver-tin-zinc-indium alloy used with adhesive luting cements were investigated. The metal surfaces were primed with two metal conditioners designed for noble metal alloys or base metal alloys, or prepared using a Rocatec tribochemical coating unit. Two adhesive luting cements (Super-Bond CB and Panavia F 2.0) were applied. It can be concluded that airborne-particle abrasion with alumina was effective, but the effects on the bond durability of both the metal conditioners and the tribochemical silica coating method were not clear Such bonding behavior seems to be particular to this kind of silver-rich dental casting alloy.

    We report that, in mice, liver autophagy makes a significant contribution to the maintenance of blood glucose by converting amino acids to glucose via gluconeogenesis. Under a synchronous fasting-initiation regimen, autophagy was induced concomitantly with a fall in plasma insulin in the presence of...

    We found that inflammatory cytokines interleukin (IL)-1beta and IL-6 induced expression of SOCS-3 but not that of SOCS-2 in human PDL cells. IL-1beta and IL-6 simultaneously induced IL-8 and monocyte chemoattractant protein-1 secretion in PDL cells, whereas SOCS-3 overexpression suppressed secretion...
