Laparoscopic anterior hepatic transection for resecting lesions originating in the paracaval portion of the caudate lobe (with videos).

Background: The paracaval portion of the caudate lobe is located in the core of the liver. Lesions originating in the paracaval portion often cling to or even invade major hepatic vascular structures. The traditional open anterior hepatic transection approach has been adopted to treat paracaval-originating lesions.

Laparoscopic middle-hepatic-vein-guided anatomical hemihepatectomy in the treatment of hepatolithiasis: a 10-year case study.

Background: This retrospective 10-year case study evaluated the perioperative results and long-term efficacy of laparoscopic middle-hepatic-vein-guided hemihepatectomy (L-MHV-H) and traditional anatomical hemihepatectomy (TAH) in the treatment of hepatolithiasis (HL).

Methods: From January 2010 to December 2019, 99 patients with regional HL underwent laparoscopic anatomical hemihepatectomy (LAH) at our centre, including 43 patients in the L-MHV-H group and 56 patients in the TAH group.

Results: All patients in both groups were Child-Pugh grade A before operation.

Ratiometric detection of amyloid-β aggregation by a dual-emissive tris-heteroleptic ruthenium complex.

A dual-emissive tris-heteroleptic ruthenium complex is designed, synthesized and applied for the ratiometric photoluminescent detection of amyloid-β (Aβ) aggregation in both steady and transient states. The Aβ aggregation is supported by transmission electron microscopy and confocal laser scanning microscopy analysis. In addition, molecular docking calculations have been performed to gain insights into the interaction mode between the ruthenium complex and Aβ fibrils.

Electrochromism in Electropolymerized Films of Pyrene-Triphenylamine Derivatives.

Two star-shaped multi-triphenylamine derivatives and were prepared, where has an additional phenyl unit between a pyrene core and surrounding triphenylamine units. The oxidative electropolymerization of and occurred smoothly to give thin films of polymers and . The electrochemistry and spectroelectrochemistry of and were examined, showing two-step absorption spectral changes in the near-infrared region.

Reduced Knoevenagel Reaction of Acetetracenylene-1,2-dione with Acceptor Units for Luminescent Tetracene Derivatives.

Acetetracenylene-1,2-dione reacted with 3-ethylrhodanine in the presence of piperidine and Hantzsch ester via a Knoevenagel condensation-reduction sequence to give a tetracene-rhodanine adduct. This reduced Knoevenagel product exhibited magenta luminescence with a fluorescence quantum yield of φ = 0.34 and fluorescence lifetime of τ = 13.

Resistive memory devices based on a triphenylamine-decorated non-precious cobalt(ii) bis-terpyridine complex.

The ITO/active material/Au sandwiched devices of a cobalt(ii) bis-terpyridine complex decorated with two triphenylamine motifs display appealing flash-type resistive switching with a large ON/OFF ratio (>10) and low operating voltages (<±3 V). In contrast, devices with the triphenylamine-appended terpyridine ligand show WORM-type memory behaviour.
