Preoperative ultrasound evaluation of gastric contents in children one hour after ingestion of clear liquid: An observational study.

Background: Gastric ultrasound is an effective, non-invasive method to assess the nature and volume of gastric content in the pediatric population. Recently, the UK, European, and French Pediatric Anesthesia Societies recommend fast for clear fluids in children for 1 h. However, studies showing that 1 h of fasting is safe in the pediatric population are still scarce.

trans-Bis[1,2-bis-(diphenyl-phosphan-yl)ethane]-chlorido(ethyn-yl)ruthenium(II).

The mol-ecular structure of the title compound, trans-[Cu(C2H)Cl(C26H24P2)2], consists of an Ru(II) cation, located on an inversion centre, in an octa-hedral environment defined by two chelating phosphines, one acetyl-ide and one chloride ligand. The -C CH and the chlorine ligands are disordered over two equivalent positions (0.5 occupancy each).

Reactive Thrombocytosis Associated with Acute Myocardial Infarction following STEMI with Percutaneous Coronary Intervention.

The etiology of thrombocytosis can be classified into reactive and essential forms. The rate of thromboembolic events is higher in essential thrombocytosis, and these events include strokes, transient ischemic attacks, retinal artery or retinal vein occlusions, digital ischemia, and acute coronary syndrome. In a study of 732 medical and surgical patients with thrombocytosis, 88% had reactive thrombocytosis.

Giant coronary artery aneurysm seen on blood-pool study.

An 81-year-old man was incidentally found to have a large pericardial cyst on a chest computed tomography. Before surgical removal, an echocardiogram demonstrated that the cyst was more likely a large (7.5 cm) right coronary arterial aneurysm.

Triaryl-1,3,5-triazinane-2,4,6-triones functionalized with electron-rich Fe(II) and Ru(II) acetylide complexes: new organometallic octupoles with large hyperpolarizabilities.

The synthesis and study of a series of trinuclear organometallic triaryl-1,3,5-triazinane-2,4,6-triones functionalized by d(6)-transition metal acetylides complexes at their periphery are reported. Remarkably large hyperpolarizabilities, far superior to those of related purely organic derivatives, are measured by hyper-Rayleigh scattering (HRS) for these new octupolar chromophores.

(E)-1-(3-Bromo-phen-yl)-3-(3,4-dimeth-oxy-phen-yl)prop-2-en-1-one.

The mol-ecular structure of the title compound, C(17)H(15)BrO(3), consists of a bromo-phenyl and a 3,4-dimeth-oxy-phenyl group linked through a prop-2-en-1-one spacer. The C=C double bond displays an E conformation, while the carbonyl group shows an S-cis conformation relative to the double bond.

Synthesis, spectral, structural, second-order nonlinear optical properties and theoretical studies on new organometallic donor-acceptor substituted nickel(II) and copper(II) unsymmetrical Schiff-base complexes.

The synthesis, spectroscopic and structural characterization, linear and nonlinear optical properties, as well as the electrochemical behavior of a series of robust neutral binuclear M[Fc-C(O)CH=C(CH(3))N-X-N=CH-(2-O,5-R-C(6)H(3))] (M = Ni (4), Cu (5), X = o-C(6)H(4), R = H; M = Ni (9), X = CH(2)CH(2), R = OH), and their corresponding ionic trinuclear [M{Fc-C(O)CH=C(CH(3))N-X-N=CH-(eta(6)-2-O,5-R-C(6)H(3))RuCp*}][PF(6)] (6, 7, 10), M[ONNO]-type unsymmetrical Salophen and salen complexes featuring ferrocenyl (Fc) donor and the mixed sandwich acceptor [Cp*Ru(eta(6)- salicylidene)](+) as a push-pull moiety are reported in this paper (Fc = CpFe(eta(5)-C(5)H(4)); Cp = eta(5)-C(5)H(5); Cp* = eta(5)-C(5)Me(5)). The single-crystal X-ray structure of the bimetallic iron-nickel derivative 4 indicates a bowed structure of the unsymmetrical Schiff base skeleton. The Ni(II) ion is tetracoordinated in a square planar environment, with two nitrogen atoms and two oxygen atoms as donors.

"Acute takeoff" of the circumflex artery: a newly recognized coronary anatomic variant with potential clinical consequences.

Human coronary anatomy allows for a wide range of anatomic variants while maintaining certain consistent features. The use of specific descriptions and names is helpful in talking about variants that have an implicit potential for clinical consequences. In reviewing the angiograms of 813 patients, we newly identified a coronary pattern that we propose to name "acute takeoff of the circumflex artery" in 16 patients (2%).
