Presence of Toxic Heavy Metals in Platelet-Rich Fibrin: a Pilot Study.

abstract：:A series of microcalorimetric experiments were performed to investigate the effect of La(3+) on the formation of the competent state of Escherichia coli HB101 by using a LKB-2277 BioActivity Monitor at 37 C. The thermogenic curves in the absence and in the presence of La(3+) were obtained. Based on these curves, we ca...
