This case-control study was done at an emergency medical center of a university hospital. 52 patients with neurological symptoms
were enrolled (28 Ischemic Stroke Group and 24 Non-Stroke Group). In the ROC analysis of IMA index to diagnose stroke, area under the curve (AUC) was 0.990 (cutoff value 91.4; 95% CI: 0.970-1.000; sensitivity: 95.8%; specificity: 96.4%). The AUC for IMA value was 0.928 (cutoff value 98 U/ml; 95% CI: 0.857-0.999; sensitivity: 87.5%; specificity: 89.3%). The difference between progression (n = 12) and non-progression group (n = 16) in IMA and IMA index were statistically insignificant (p > 0.01). IMA index was more sensitive than conventional IMA value as diagnostic biomarker of stroke, however, arguable as a predictive biomarker for progression of ischemic stroke.”
the effects of depolarization on the excitonic Rabi oscillation in SRT2104 GaAs thin films measured in the 2k(1) – k(2) direction of a degenerate four-wave-mixing signal. The Rabi frequency, measured by changing the k(2) pulse intensity, varies with the k(1) pulse intensity; the Rabi frequency decreases with an increase in the k(1) power. This decrease originates from the reduction in the field intensity of the k(2) pulse, which consists of the local field and depolarization terms. Cancellation of the k(2) field due to depolarization leads YH25448 concentration to the decrease in the Rabi frequency. (C) FK228 in vitro 2011 American Institute of Physics. [doi:10.1063/1.3624667]“

“The effects of selective distribution of carbon black (CB) particles and spatial confinement on the crystallization behavior of isotactic polypropylene (iPP)/Polystyrene (PS)/CB composite were studied.
The crystallization behaviors and the morphologies of the composite were studied by differential scanning calorimetry (DSC), polarized light microscope (PLM), and scanning electron microscopy (SEM). The results indicated the typical cocontinuous structure appeared in PP/PS/CB (55/45/1) composite, and CB particles are distributed in PS phase, which follows the theory of interfacial tension. Compared with PP/CB composite, the nucleation effect of CB particles on the crystallization process of PP in PP/PS/CB was greatly weakened by selective distribution. Moreover, the morphologies of cocontinuous structure, which means that the crystallization process of PP had to take place in the micron-scale spatial confinement formed by continuous PS phase, greatly influenced the crystallization behavior of PP in PP/PS/CB composite.
