Robotic liver parenchymal transection techniques: a comprehensive overview and classification.

Robotic liver surgery is experiencing a period of great development, but some hurdles still need to be overcome. Parenchymal transection remains one of the most technically challenging steps. The lack of dedicated instruments and the flourishing of several techniques didn't allow surgeons to reach a standard technique so far.

Robotic versus laparoscopic liver resection for difficult posterosuperior segments: a systematic review with a meta-analysis of propensity-score matched studies.

Background: The outcomes of minimally invasive liver surgery for posterosuperior segments (PS) are still debated. Since the results of ongoing trials focusing on the results of laparoscopic liver resection (LLR) and robotic liver resection (RLR) in this setting are still awaited, the best evidence currently comes from retrospective propensity-score matched (PSM) studies. The aim of this meta-analysis was to assess the outcomes of RLR for difficult located lesions and to provide evidence for its use in clinical practice.

Renewable proteins from agricultural and animal sources as innovative multifunctional bio-fillers for rubber composites: A comprehensive review.

There is a growing need to find novel, sustainable solutions for elastomer reinforcement. Many biomass polymers have been used for this purpose, including cellulose, starch, lignin and protein. Among these, proteins are an under-explored solution, although they are promising materials due to their abundance in agricultural and animal by-products and the multifunctional properties they can impart to composites.

The x-ray absorption spectrum of the tert-butyl radical: An experimental and computational investigation.

We report the x-ray absorption spectrum (XAS) of the tert-butyl radical, C4H9. The radical was generated pyrolytically from azo-tert-butane, and the XAS of the pure radical was obtained by subtraction of spectra recorded at different temperatures. The bands in the XAS were assigned by ab initio calculations that are in very good agreement with the experimental data.
