Feasibility of robotic-assisted surgery in advanced rectal cancer: a multicentre prospective phase II study (VITRUVIANO trial).

Background: The potential benefits of robotic-assisted compared with laparoscopic surgery for locally advanced cancer have not been sufficiently proven by prospective studies. One factor is speculated to be the lack of strict surgeon criteria. The aim of this study was to assess outcomes for robotic surgery in patients with locally advanced rectal cancer with strict surgeon experience criteria.

Synthesis of the A/D/E-ring Core Compounds of Maoecrystal V†.

Synthesis of the A/D/E-ring core compounds of maoecrystal V was achieved. The key Diels-Alder reactions between tricyclic α-methylene lactones and Kitahara-Danishefsky dienes afforded the spirocyclic core compounds in a regioselective and stereoselective manner.

Effect of light exposure on circadian rhythm in theront excystment in Cryptocaryon irritans.

We examined the effects of light exposure on the theront excystment circadian rhythm in Cryptocaryon irritans using a newly invented apparatus, which enabled us to examine the excystment rhythms of theronts from tomonts with low labor. Using the apparatus, we examined the timings of theront excystment from tomonts exposed directly to light and from tomonts exposed to light-exposed seawater by counting the number of excysted theronts. We found that the theront excystment time changed only when tomonts were directly exposed to light, indicating that light reception is essential for circadian rhythm entrainment.

Effect of Biokos, a natural lipopeptide surfactant extracted from a bacterium of the Pseudomonas genus, on infection of Cryptocaryon irritans.

Cryptocaryoniasis (marine white spot disease), caused by Cryptocaryon irritans, is a major threat to marine fish cultures in tropical and subtropical waters, and a serious nuisance to hobbyists with saltwater fish tanks. With only classical treatment schedules such as copper salts or hyposaline baths being available, control of the disease remains a challenge. In this study, we investigated the effect of Biokos, a viscosin-like lipopeptide surfactant extracted from a bacterium of the Pseudomonas genus, on the external life stages of C.

Target Protein Expression on Tetrahymena thermophila Cell Surface Using the Signal Peptide and GPI Anchor Sequences of the Immobilization Antigen of Cryptocaryon irritans.

Cryptocaryoniasis, caused by Cryptocaryon irritans, is a significant threat to marine fish cultures in tropical and subtropical waters. However, controlling this disease remains a challenge. Fish infected with C.
