Background: Despite the increasing use of robotic distal gastrectomy (RDG) in patients with gastric cancer (GC), its safety and efficacy compared to those of laparoscopic distal gastrectomy (LDG) have not been elucidated in a randomized controlled trial (RCT). We aimed to evaluate the short-term outcomes of patients with GC who received RDG or LDG. Methods: Three hundred patients with cT1-4a and N0/+ between September 2017 and January 2020 were enrolled in this RCT at a high-volume hospital in China. The short-term outcomes were compared between the groups.

Highlights d The crystal structures of YFV-E in both pre-and post-fusion states are determined d A neutralizing monoclonal antibody engages YFV-E in both states as a double lock d This monoclonal antibody inhibits YFV infection at multiple steps of virus entry

A harvest of at least 21 LNs may represent a superior threshold for radical total gastrectomy (RTG) and could yield a better prognosis. For patients undergoing RTG, the hTNM staging system may predict survival more accurately and discriminatively. However, a validation from a Western institution is warranted.

Recent theoretical developments that facilitate characterization of excited-state potential energy surfaces are applied to study five stationary points on the S1 surface of C2H2. Although previous calculations have focused on the acetylenic trans and cis forms, the present research predicts that the vinylidene isomer is the global minimum on the potential surface. However, a high activation barrier calculated for rearrangement to the trans isomer suggests that S1 vinylidene is not likely to be formed via photoexcitation of ground-state acetylene. The trans and cis acetylenic forms of the S1 state are shown to interconvert along an in-plane reaction coordinate with an activation energy of ∼4000 cm−1, a value which is significantly lower than usually assumed in spectroscopic analyses.
