TL;DR: The majority of colonic and rectal superficial lesions can be effectively removed in a curative way by standard polypectomy and/or by EMR, and ESGE recommends ESD as treatment of choice for most gastric superficial neoplastic lesions.

TL;DR: Endoscopic ultrasonography findings can predict complete tumor resections and ESD is an effective and relatively safe method for removing gastric subepithelial tumors.

TL;DR: It is suggested that circulating bile acids are altered differentially in primary biliary cirrhosis and primary sclerosing cholangitis patients.

TL;DR: It is demonstrated that biliary obstruction affects differentially the circulating and/or urinary levels of the various bile acids, and the observation that the most drastically affected acids correspond to the less toxic species supports the activation of self-protecting mechanisms aimed at limiting the inherent toxicity of biliary acids in face of bile obstruction.

TL;DR: All BA-G assayed were less toxic and displayed lower pro-apoptotic/necrotic effects than their unconjugated precursors, even if they were able to penetrate into HepG2 cells.
