“Electrochemical-catalytic conversion via the electrochemical-catalytic cell (ECC) is effective at 400 degrees C for simultaneous NOx and hydrocarbons emissions control of lean-burn gasoline engine without consuming any reductant. The NO reaction is direct NO decomposition. The NOx to N-2 rate over the cathode of the ECC can be three orders larger than those

over conventional oxide catalysts for NO decomposition. In the high NOx concentration region, the NO conversion increases with increasing NOx concentration; Screening Library nmr this characteristic allows the engine to be operated at high enough temperature with excess oxygen to result in maximum fuel efficiency. In the low NOx concentration region, the NO conversion selleck chemicals also increases with decreasing

NOx concentration; this characteristic enables complete conversion of NO and thus can result in zero NOx emission. The NO conversion increases with decreasing temperature, at least till 400 degrees C. Higher oxygen concentration is beneficial to both the NO conversion and the hydrocarbons oxidation to result in zero pollution. (C) 2011 Elsevier B.V. All rights reserved.”
“Choice reaction times are shorter when stimulus and response locations are compatible than when they are incompatible as in the Simon effect. Recent studies revealed that Simon effects are strongly attenuated when there is temporal overlap with a different high-priority task, accompanied by a decrease of early location-related response priming as reflected in the lateralized readiness potential (LRP). The latter result was obtained in a study excluding overlap of stimulus location with any other dimension in the tasks. Independent evidence suggests that location-related priming might be present in conditions with dimensional overlap. Here we tested this prediction in a dual-task experiment supplemented with recording LRPs. The

secondary task was either a standard Simon task where irrelevant stimulus location JNJ-26481585 nmr overlapped with dimensions of the primary task or a Stroop-like Simon task including additional overlap of irrelevant and relevant stimulus attributes. At high temporal overlap, there was no Simon effect nor was there stimulus-related response priming in either condition. Therefore stimulus-triggered response priming seems to be abolished in conditions of limited capacity even if the likelihood of an S-R compatibility effect is maximized.”
“Tamoxifen-resistant breast cancer is a major clinical problem and new treatment strategies are highly warranted. In this study, the multitargeting kinase inhibitors sorafenib and nilotinib were investigated as potential new treatment options for tamoxifen-resistant breast cancer. The two compounds inhibited cell growth, reduced expression of total estrogen receptor alpha (ER), Ser118-phosphorylated ER, FOXA1 and AIB1 and resensitized tamoxifen-resistant cells to tamoxifen.
