(S)-(+)-N-Benzyl-idene-1-(1-naphth-yl)ethyl-amine.

In the title chiral aldimine, C(19)H(17)N, the azomethine group is not fully conjugated with the phenyl substituent: the dihedral angle between phenyl and C(*)-N=C mean planes is ϕ(3) = 23.0 (2)°. Compared with the earlier DFT-B3LYP/6-31 G(d) computations from the literature, the C=N-C(*)-C(naph-thyl) torsion angle, found at ϕ(2) = -118.

(-)-(S)-N,N'-Bis[1-(1-naphth-yl)eth-yl]-oxalamide.

The title mol-ecule, C(26)H(24)N(2)O(2), displays C(2) symmetry, with the mol-ecule located on a twofold axis perpendicular to the plane of the oxalamide unit -NH-CO-CO-NH-. The oxalamide core deviates from planarity, as reflected by the O=C-C=O and N-C-C-N torsion angles of 164.3 (5) and 163.

[Gastric cancer and laparoscopy: analysis of data from the national register of laparoscopic gastric surgery].

Objective: To study the data from the Laparoscopic Gastric Surgery Spanish National Register of laparoscopic Gastric Surgery and to analyse the type of surgery, the conversion to laparotomy, postoperative complications and mortality.

Patients And Method: From March 2005 to July 2008, details of 302 laparoscopic gastric surgical interventions were sent to the Association of Spanish Surgeons web-site. Details of surgical technique, reconversion, clinical and pathological data, morbidity and mortality were collected and analysed.

Detection of West Nile virus in the Mexican blood supply.

Background: West Nile virus (WNV) is the etiologic agent of an emerging disease in the Western Hemisphere that can be transmitted to humans by blood transfusion. WNV first appeared in the United States in 1999, in Canada in 2001, and in Mexico in 2002. The aim of this nationwide study was to determine the prevalence of WNV in blood donors in Mexico as a first step in preventing its transfusion-associated transmission.
