[Digital transformation of perioperative nurse-coordinated protocols in renal surgery for enhanced recovery and outpatient surgery using UroConnect® application].

Robot Assisted Partial Nephrectomy (RAPN) is a standard of care for localized renal tumors. It allows a good carcinological control while limiting complications. Despite numerous benefits, the economic sustainability of robotic assistance remains a challenge in the French health care system.

[Targeting for drug delivery and imaging: an overview of the state of the art in cancer].

The concept of drug targeting has resulted in a considerable variety of tools within nanotechnology, whose potentials in the special field of cancer are very interesting. There is a strong link between the structure and the surface of the vector on the one hand, and the biological target thus accessible on the other hand, as illustrated a number of typical examples. Parallel developments were made in the fields of therapy and diagnosis, stage by stage.

Interaction of an amphiphilic squalenoyl prodrug of gemcitabine with cellular membranes.

We have designed an amphiphilic prodrug of the anticancer agent gemcitabine (dFdC), by covalent coupling to squalene. This bioconjugate, which self-assembled into nanoparticles (NPs) in water, was previously found to display an impressive anticancer activity both in vitro and in vivo. The present study aims to investigate the impact of SQdFdC nanoparticles on cellular membranes.

Prodrug-based intracellular delivery of anticancer agents.

There are numerous anticancer agents based on a prodrug approach. However, no attempt has been made to review the ample available literature with a specific focus on the altered cell uptake pathways enabled by the conjugation and on the intracellular drug-release mechanisms. This article focuses on the cellular interactions of a broad selection of parenterally administered anticancer prodrugs based on synthetic polymers, proteins or lipids.

PEGylation and preliminary biocompatibility evaluation of magnetite-silica nanocomposites obtained by high energy ball milling.

High energy ball milling (HEBM) has been used for the first time to prepare PEGylated magnetite-silica (Fe(3)O(4)-SiO(2)) nanocomposites intended to be used for biological purposes. Surface amine groups were introduced by a silanization reaction involving 3-aminopropyl triethoxysilane (APTS) followed by PEGylation to yield long-term stable and stealth nanocomposites of 200nm in diameter. The efficient coverage by PEG chains was shown by isothermal titration calorimetry (ITC) where PEGylated nanocomposites did not interact with BSA compared to non-PEGylated counterparts which led to a significant change in enthalpy.
