To the Editor: I read with interest the study by Kitamura et al published in a recent issue of Circulation. 1 This nationwide, population-based study found significantly higher rate of favorable neurological outcome in the conventional-cardiopulmonary resuscitation (CPR) group compared to the compression-only-CPR group for out-of-hospital cardiac arrest (OHCA) of noncardiac origin (NCO). Howeve...

We perform a double line of sight (DLOS) analysis of the Lyα forest structures that form and evolve in cosmological N–body/hydrodynamic simulations. Pairs of simulated spectra, extracted from lines of sight separated by distances from D = 12.5 kpc up to 800 kpc, and a “control sample” of unrelated lines of sight, are analyzed at redshifts 3, 2, and 1. Coincident line samples are defined for HI ...

BACKGROUND Coronary Heart Disease (CHD) is one of the most common and life-threatening diseases in both developed and developing countries and a close correlation has been found between different types of obesity and CHD. OBJECTIVES The current study investigated the relationship between central obesity and coronary heart disease risk factors in CHD referral outpatients to Khatam Clinic, Zahe...

In the title compound, C(10)H(12)N(2)OS, the amide NCO group is twisted relative to the thio-ureido SCN(2) group, forming a dihedral angle of 55.3 (2)°. The crystal packing shows inter-molecular N-H⋯S and weak C-H⋯O inter-actions, the former giving rise to the formation of centrosymmetric R(2) (2)(8) dimers.

Two new end-to-end (EE) cyanate bridged 1D coordination polymers of Ni(II) are isolated which contain linear (180°) Ni-N-C and Ni-O-C angles in Ni-NCO-Ni bridges and show ferromagnetic (F) coupling in agreement with the reported theoretical model for linear EE bridges.

Reaction of nickel(II) chloride with sodium cyanate and 2,6-di-methyl-pyrazine leads to single crystals of the title com-pound, [Ni(NCO)(2)(C(6)H(8)N(2))(4)]. The nickel(II) cation is located about a centre of inversion and is octa-hedrally coordinated by two cyanate anions and four 2,6-dimethyl-pyrazine ligands, forming discrete complexes.

Social dynamic opinion models have been widely studied to understand how interactions among individuals cause opinions to evolve. Most opinion models that utilize spin interaction models usually produce a consensus steady state in which only one opinion exists. Because in reality different opinions usually coexist, we focus on non-consensus opinion models in which above a certain threshold two ...

Reactions of [Pd(styrene)(PR3)2], generated from trans-[PdEt2(PR3)2] and styrene, with 2 equiv. of benzyl isocyanate in THF at room-temperature afforded unusual cyclic Pd-tetramers of five-membered rings consisting of organic isocyanate dimers and palladium, [Pd(PR3){-C(O)N(R)C(O)N(R)-}]4 (PR3 = PMe3, ; PR3 = PMe2Ph, ). Additionally, a cyclic trimer, (RNCO)3, (R = benzyl) was produced as a cata...

The flexible zwitterionic dicarboxylate ligand 1,4-bis(4-carboxylato-1-pyridinium)butane (bcpb) assumes different conformations to collaborate with pseudohalides in various coordination modes to produce coordination polymers in which distinct anionic motifs with mixed carboxylate and pseudohalide bridges are interlinked by the cationic butylenebis(pyridinium) tethers. The Cu(II) compound, [Cu2(...
