“Partial substitution of various transition metals for Al

in 10Al(2)O(3)center dot 2B(2)O(3) (Al20B4O36, 10A2B) was studied to use as a thermostable support for Pd catalysts. Fe-substitution VX-661 afforded the formation of solid solutions in the range of x <= 1.5 in FexAl20-xB4O36 (Fe-10A2B) without impurities. The DFT calculations confirmed that Fe-substitution was most likely to occur on the 5-coordinated Al site and predicted a shorter Fe-O distances of 1.84-2.05 angstrom compared to 1.94 and 2.12 angstrom in Fe2O3, in accordance with Fe-K edge EXAFS results. Fe-substitution improved the catalytic NO conversion in a rich region (A/F < 14.6), because CO-H2O and subsequent NO-H-2 reactions were accelerated. The redox between Fe3+ and Fe2+ in Fe-10A2B generated the oxygen storage capacity (OSC), which yielded an efficient buffering effect AZD1480 purchase on air-to-fuel (A/F) fluctuation in a simulated exhaust gas stream with lean/rich perturbation. These results suggest that Fe-10A2B is expected to be used as

a multifunctional support material for Pd catalysts in automotive three-way catalysts. (C) 2013 Elsevier B.V. All rights reserved.”
“Background: Set-shifting is impaired in people with anorexia nervosa (AN), but the underlying physiological NVP-HSP990 datasheet and biochemical processes are unclear. Animal studies have established that glutamatergic pathways

in the prefrontal cortex play an important role in set-shifting ability. However, it is not yet understood whether levels of serum glutamatergic amino acids are associated with set-shifting performance in humans. The aim of this study was to determine whether serum concentrations of amino acids related to glutamatergic neurotransmission (glutamine, glutamate, glycine, L-serine, D-serine) are associated with set-shifting ability in people with acute AN and those after recovery.\n\nMethods: Serum concentrations of glutamatergic amino acids were measured in 27 women with current AN (AN group), 18 women recovered from AN (ANRec group) and 28 age-matched healthy controls (HC group). Set-shifting was measured using the Wisconsin Card Sorting Test (WCST) and the Trail Making Task (TMT). Dimensional measures of psychopathology were used, including the Eating Disorder Examination Questionnaire (EDEQ), the Maudsley Obsessive-Compulsive Inventory (MOCI) and the Hospital Anxiety and Depression Scale (HADS).\n\nResults: Serum glutamine concentrations in the AN group (1,310.2 +/- 265.6 mu M, mean +/- SD) were significantly higher (by approximately 20%) than those in the HC group (1,102.9 +/- 152.7 mu M, mean +/- SD) (F-(2,F- 70) = 6.3, P = 0.003, 95% CI 61.2 to 353.4).
