Stimulated by 980 nm infrared laser, the green photostimulated luminescence was first observed in a nondoped oxide. After ultraviolet irradiation, the green persistent luminescence of Mg2SnO4 could be seen in darkness for about 5 h. The decay curves revealed that the long persistent luminescence was governed by tunneling mechanism and it proved the presence of

different trap clusters in Mg2SnO4. These trap clusters (such as [Sn-Mg(center dot center dot)-O-i ''], [Sn-Mg(center dot center dot)-2e'], and [Sn-Mg(center dot center learn more dot)-e '']) induced the trap levels with different depths in band gap and corresponded to the three components (at 110, 168, and 213 degrees C) of the thermoluminescence glow curve of Mg2SnO4. These trap levels with different depths were proved to be not independent. It revealed that the shallow traps (110 degrees C) and part of the deep traps (168 and 213 degrees C) were involved in the persistent luminescence. Meanwhile, all the shallow and deep traps were

responsible for the photostimulated luminescence. Accordingly, the photoluminescence, persistent, and photostimulated luminescence mechanisms of the nondoped Mg2SnO4 material were first proposed. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3524280]“
“Ictal behavior coupled with SPECT findings during 28 seizures in patients with temporal lobe epilepsy (TLE) with unilateral hippocampal sclerosis (13 left; 15 right) was displayed as flowcharts from right-sided (RTLE) plus left-sided (LTLE) seizures. Ictal SPECT was classified CX-4945 ic50 blind to neuroethology. Behaviors were categorized as ipsilateral to the epileptogenic zone (IL), contralateral to the epileptogenic zone (CL), or bilateral. SPECT

intensity and region were categorized as IL VX-680 in vivo or CL to the epileptogenic zone. All patients developed automatisms and had hyperperfusion in their temporal lobes. Patients’ verbal responses to questions had statistical interactions in RTLE but not in LTLE sum. Most CL dystonic posturing was correlated to IL basal ganglia hyperperfusion. Basal ganglia activation occurred in seizures without dystonic posturing and CL manual automatisms, and lack of IL dystonic posturing and the presence of CL cerebellar hemispheric hyperperfusion were also observed. Coupling of neuroethology and SPECT findings reliably evaluates ictal behavior and functionality of associated brain areas. (C) 2010 Elsevier Inc. All rights reserved.”
“The likelihood of a sustained virological response (SVR) is the most important factor for physicians and patients in the decision to initiate and continue therapy for chronic hepatitis C (CHC) infection. This study identified predictive factors for SVR with peginterferon plus ribavirin (RBV) in patients with CHC treated under ‘real-life’ conditions.
