Recurrent Pelvic Organ Prolapse after Sacrocolpopexy-A Surgical Challenge.

: Repeat sacrocolpopexy (reSCP) for recurrent pelvic organ prolapse (POP) is a rare and complex condition with little understanding of how to manage. Most authors recommend complete reSCP regardless of the underlying cause of the failure. This retrospective cohort study presents our management workflow and how to systematically approach this challenging situation.

Nanoparticle cytotoxicity depends on intracellular solubility: comparison of stabilized copper metal and degradable copper oxide nanoparticles.

Metal nanoparticles have distinctly different chemical and physical properties than currently investigated oxides. Since pure metallic nanoparticles are igniting at air, carbon stabilized copper nanoparticles were used as representative material for this class. Using copper as a representative example, we compare the cytotoxicity of copper metal nanoparticles stabilized by a carbon layer to copper oxide nanoparticles using two different cell lines.
