BACKGROUND/AIMS As a result of increased surgeon's experience and the improvement in laparoscopic techniques, laparoscopic gastrectomy has been widely accepted for the management of early stage gastric cancer. Sufficient evidence has demonstrated the feasibility of laparoscopy-assisted distal gastrectomy for early gastric cancer. Radical laparoscopic(More)
BACKGROUND/AIMS Conventional open total gastrectomy in patients with IV stage or metastatic gastric carcinoma in the middle or upper third of the stomach is under controversy due to its poor prognosis and its surgical complexity. Based on advances in laparoscopic equipment, techniques, and ongoing experience in laparoscopically- assisted D2 total(More)
BACKGROUND Military personnel commonly serve as first responders to natural disasters. Our aim is to identify Post-Traumatic Stress Disorder (PTSD) and determine risk in military responders to the Wen Chuan earthquake. METHODS Analyses were carried out on 1056 of the 1125 soldiers enrolled. In addition to social demographic characteristics, the Davidson(More)
The title compound, C(17)H(16)N(2)O(3), crystallizes with two independent mol-ecules in the asymmetric unit. In both mol-ecules, the fused cyclo-hexenone ring adopts a sofa conformation. In the crystal, N-H⋯N and N-H⋯O hydrogen bonds link the mol-ecules into corrugated layers parallel to the (101) plane.
Developing high-performance but low-cost hydrogen evolution reaction (HER) electrocatalysts with superior activity and stability for future sustainable energy conversion technologies is highly desired. Tuning of microstructure, configuration, and chemical composition are paramount to developing effective non-noble electrocatalysts for HER. Herein, a(More)
In the title compound, [Sn(CH3)3(C7H7N2O2S)(H2O)], the Sn(IV) atom has a distorted trigonal-bipyramidal coordination geometry, with one carboxyl-ate O atom of the 2-(4-methyl-pyrimidine-2-sulfan-yl)acetate ligand and the O atom of a water mol-ecule in axial positions, and three methyl groups in equatorial positions. In the crystal, mol-ecules are linked via(More)
In the title compound, [Sn(C(6)H(5))(2)(C(11)H(11)NO(4))], the tin(IV) atom is penta-coordinated in a distorted trigonal-bipyramidal SnC(2)NO(2) geometry. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers. Weak C-H⋯O inter-actions further link the dimers into chains extending in [010].
In the title compound, C(18)H(14)N(2)O(2)·H(2)O, the dihedral angle between the benzene ring and the naphthalene system is 5.18 (10)°. Intra-molecular N-H⋯O hydrogen bonds influence the molecular conformation. In the crystal, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds are observed as well as π-π inter-actions between the phenyl ring and the substituted(More)
