Summary The aim of the present study was to determine the precision of the PiCCO® system for post-cardiac arrest patients who underwent therapeutic hypothermia. The precision of the measurements for cardiac output, global end-diastolic volume, extravascular lung water and the pulmonary vascular permeability index was assessed using the least significant change; this was regarded as precise when less than 15%. A total of 462 measurement sets were prospectively performed on 88 patients following successful resuscitation after cardiac arrest. Using the mean value of three injections for a measurement, the least significant change for the cardiac output, global end-diastolic volume, extravascular lung water and pulmonary vascular permeability index measurements were found to be 7.8%, 8.5%, 7.8% and 12.1%, respectively. No significant differences between hypothermia (n = 150) and non-hypothermia (n = 312) were found. The PiCCO-derived variables were found to be precise for post-cardiac arrest patients even under conditions of varying body temperature. [ABSTRACT FROM AUTHOR]

The title complex was a Mott insulator, in which the head-to-head type dimer of newly synthesized donor molecule, 2-(thiapyran-4-ylidene)-4,5-ethylenedioxy-1,3-dithiole (TP-EDOT) accommodated a localized spin. Although the localized spins were arranged in three-dimensional (3D) framework, the interaction between them was interpreted as a two-dimensional (2D) spin system. The ability of TP-EDOT to exhibit intermolecular interactions along the molecular longitudinal axis allowed to form a head-to-head dimer, which provided an elongated space to reserve a localized spin. The anisotropy of this dimer was regarded to be the origin of the novel 2D spin structure formed in the 3D lattice. [ABSTRACT FROM AUTHOR]

The authors investigated the magnetic anisotropy of epitaxial films of γ-Fe2O3(001) composed entirely of Fe3+. The cubic anisotropy term (K1) was negligibly small (K1≈-2.7×104 erg/cm3), as expected for L≈0 systems; however, substantially large uniaxial anisotropy energy (Ku≈6.1×105 erg/cm3) was found as the thickness reached the bulk limit. A detailed characterization of both the in-plane and out-of-plane lattice parameters revealed that the c/a ratio of the unit cell was intrinsically elongated due to its vacancy-ordered supercell. This unexpectedly large Ku is reasonably explained by simple dipole sums if the authors take into account the slightly stretched unit cell (c′/a=1.03) in the growth direction even without the spin-orbit interaction.
