Ni Nanoparticles on the Reduced Graphene Oxide Surface Synthesized in Supercritical Isopropanol.

Nanocomposites based on ferromagnetic nickel nanoparticles and graphene-related materials are actively used in various practical applications such as catalysis, sensors, sorption, etc. Therefore, maintaining their dispersity and homogeneity during deposition onto the reduced graphene oxide substrate surface is of crucial importance to provide the required product characteristics. This paper demonstrates a new, reproducible method for preparing a tailored composite based on nickel nanoparticles on the reduced graphene oxide surface using supercritical isopropanol treatment.

The role of telemedicine in the postoperative home monitoring after robotic colo-rectal cancer surgery: a preliminary single center experience.

The telemedicine studies, takes care and prevents diseases at distance basing on the interaction among physicians and patients remotely. Few data are available on its application to early postoperative after surgery. The endpoints of our preliminary experience were the detection, as primary, of feasibility and safety of home telemonitoring after robotic colo-rectal resection and, as secondary, perception and satisfaction of the patients.

ICG-NIR-guided lymph node dissection during robotic subtotal gastrectomy for gastric cancer. A single-centre experience.

Background: Near-infrared (NIR) fluorescence imaging with indocyanine green (ICG) allows intraoperative visualisation of the lymph nodes (LNs) draining the tumour.

Methods: We included in our study 20 patients who underwent robotic subtotal gastrectomy + D2 lymphadenectomy for gastric cancer. In 10 cases, intraoperative ICG-guided lymphography has been used (Group A).

Safety profile and oncological outcomes of gastric gastrointestinal stromal tumors (GISTs) robotic resection: Single center experience.

Background: Although usefulness of robot assisted surgery has been largely reported and accepted, robot assisted gastrointestinal stromal tumor (GIST) treatment is rare. Hence, the aim of this study is to report a single center evaluation on gastric GIST's robotic resection.

Methods: Six patients were analyzed focusing on safe (conversion/complications rate, hospital stay), oncological (margin resection, recurrence rate), and feasible (operative time, technical tip, and tricks) profile of robotic-assisted GIST surgery.

Comparison of macular thickness measurements between time-domain and spectral-domain optical coherence tomographies in eyes with and without macular abnormalities.

Purpose: To compare Stratus time-domain optical coherence tomography (OCT) with Cirrus spectral-domain HD-OCT for measuring macular thickness in eyes with and without macular abnormalities.

Methods: Seventy-five eyes of 48 patients were included in the study. Forty-one eyes of 29 patients had a normal macular thickness, and 34 eyes of 26 patients had an abnormal macular thickness.
