No interventions have yet been identified to reduce the risk of acute kidney injury in setting cardiac surgery.To determine whether remote ischemic preconditioning reduces rate and severity patients undergoing surgery.In this multicenter trial, we enrolled 240 at high for injury, as by a Cleveland Clinic Foundation score 6 or higher, between August 2013 June 2014 4 hospitals Germany. We randomized them receive sham (control). All completed follow-up 30 days after surgery were analyzed...
We present an ab initio description of the spin Hall effect in metals. Our approach is based on density functional theory framework a fully relativistic Korringa-Kohn-Rostoker method and solution linearized Boltzmann equation including scattering-in term (vertex corrections). The skew scattering mechanism at substitutional impurities considered. Spin-orbit coupling host as well impurity atom influence spin-flip processes are taken into account. A sign change Cu Au hosts obtained function...
On the basis of detailed ab initio studies, influence strain on anisotropy transport distribution thermoelectrics Bi${}_{2}$Te${}_{3}$ and Sb${}_{2}$Te${}_{3}$ was investigated. Both tellurides were studied in their own as well copartner's lattice structure to gain insight into electrical epitaxial heterostructures composed both materials. It is shown that overestimates experimental findings for Bi${}_{2}$Te${}_{3}$, implying anisotropic scattering effects. An increase in-plane constant...
Background Previously, the authors developed and characterized a rat model for postoperative pain to learn more about produced by incisions. In this study, responses heat mechanical stimuli were evaluated directly on or adjacent incision at varying distances from incision. Methods Rats anesthetized with halothane incisions made different locations in plantar aspect of foot. The response frequency blunt stimulus, withdrawal threshold von Frey filaments (15-522 mN), latency radiant measured....
Background Evidence from experiments by others indicates an important role for excitatory amino acids activating spinal n-methyl-d-aspartate (NMDA) receptors in models of persistent pain. The purpose this study was to examine the effect intrathecal (+)-5-methyl-10,11-dihydro-5H-dibenzo(a,d)cyclohepten-5,10-imine (MK-801), a noncompetitive NMDA receptor antagonist, 2-amino-5-phosphonovaleric acid (AP5), competitive and N-G-nitro-L-arginine methyl ester (L-NAME), nitric oxide synthase...
Ab initio calculations are presented for the giant magnetoresistance (GMR) of Fe/Cr multilayers. The electronic structure superlattices is calculated within spin density functional theory. spin-dependent bulk impurity scattering treated in a fully quantum mechanical way using Green function formalism. transport described quasiclassically. suggest that GMR thin multilayers mainly determined by layered system. Spin-dependent can reduce, increase, or invert effect.
Evidence indicates that excitatory amino acids (EAAs) like glutamate and aspartate are important in the processing of nociceptive information dorsal horn spinal cord. Recently, role particular EAA receptors pain transmission facilitated states has been examined utilizing administration specific receptor antagonists. Most investigators have studied involvement N-methyl-D-aspartate (NMDA) hyperalgesia nociception; less is known about importance non-NMDA animal models persistent pain. To study...
Background To learn more about persistent pain after an incision, a rat model for postoperative has been developed. further evaluate this model, the authors examined effect of intrathecal (IT) and subcutaneous (SC) morphine, effective relief in patients, on behaviors immediately surgery 1 day surgery. Methods Rats were anesthetized with halothane, 1-cm incision was made plantar aspect foot closed. After recovery, rats placed elevated plastic mesh floor, withdrawal threshold determined using...
The Fermi surface that characterizes the electronic band structure of crystalline solids can be difficult to image experimentally in a way reveals local variations. We show surfaces imaged real space with low-temperature scanning tunneling microscope when subsurface point scatterers are present: this case, cobalt impurities under copper surface. Even very simple causes strongly anisotropic propagation characteristics bulk electrons confined beamlike paths on nanoscale. induced charge density...
We performed ab initio studies to search for materials where a large spin Hall effect caused by skew scattering is accompanied long diffusion length. Samples with such properties are promising candidates all-metallic spintronics devices. Here we consider Cu, Au, and Pt hosts which typical used in experiments. In particular, identified light impurities as C N Au heavy Bi Cu meet this criterion. They exhibit angle $(\ensuremath{\alpha}>0.06)$ an appropriate length of about 100 nm. addition,...
Magnetoelectric coupling allows for manipulating the magnetization by an external electric field or electrical polarization magnetic field. Here, we propose a mechanism to electrically induce 180° switching combining two effects: magnetoelectric at multiferroic interface and interlayer exchange coupling. By means of first-principles methods, investigate ferroelectric layer in contact with Fe/Au/Fe trilayer. The calculations show that magnetism is strongly coupled layer. Furthermore, under...
On the basis of detailed first-principles calculations and semi-classical Boltzmann transport, anisotropic thermoelectric transport properties Bi$_2$Te$_3$ Sb$_2$Te$_3$ under strain were investigated. It was found that due to compensation effects dependent thermopower electrical conductivity, related powerfactor will decrease applied in-plane for Bi$_2$Te$_3, while being stable Sb$_2$Te$_3$. A clear preference hole-doping, as well direction both tellurides. In contrast conductivity...
