Results: Compared with nonobese control subjects, severely obese patients achieved markedly higher aggregated PFS scores and subdomain scores related to generally available as well as physically present foods (all P < 0001). On the aggregated score as well in those 2 subdomains, gastric bypass patients scored significantly lower than did non-gastric bypass obese patients (all P < 0.001) and did not differ significantly from the nonobese control group (P > 0.2). In contrast, in the PFS

domain concerning food tasted, gastric bypass patients had significantly lower S63845 Apoptosis inhibitor scores than did the nonobese control subjects (P = 0.04) and the severely obese patients (P = 0.008), both of whom did not differ significantly in this measure (P = 0.90).

Conclusion: In comparison with nonobese control subjects, severely obese patients display a marked increase in hedonic hunger that is not observed in patients who have undergone gastric bypass surgery, suggesting that the operation normalizes excessive appetite for palatable foods, which

may be an important pathophysiologic feature of severe obesity. Am J Clin Nutr 2010; 92: 277-83.”
“Microporous carbon membranes (MCM) were prepared from sulfonated poly(phthalazinone ether sulfone ketone) (SPPESK) through stabilization and pyrolysis processes. The effects of sulfonation degree (SD) of SPPESK and the stabilization temperature on the structure and gas permeation of MCM were investigated. The thermal decomposition AC220 supplier behavior of SPPESK was studied by thermogravimetric analysis-mass spectrometry. The evolution of functional selleck chemical groups on membrane surface was detected by Fourier transform infrared spectroscopy during heat treatment. The resultant MCM was characterized by X-ray diffraction, Raman spectroscopy, nitrogen adsorption technique and pure gas permeation test (including the gases of H(2), CO(2), O(2), and N(2)), respectively. The results have shown that the removal of sulfonic acid groups in SPPESK leads to a weight loss stage in the

temperature range of 250-450 degrees C. The surface area, maximum pore volume, and gas permeability of MCM increase with the SD increasing from 59 to 75%, together with the reduction of selectivity. Similarly, the gas permeability of MCM also increases with elevating the stabilization temperature from 350 to 400 degrees C at the loss of selectivity. (C) 2011 Wiley Periodicals, Inc.

“Si substitution at Fe site causes the ferromagnetic to antiferromagnetic (AFM) transition at low temperatures in CeFe2. We have carried out temperature and field variation of neutron diffraction measurements on Ce(Fe0.95Si0.05)(2) to unravel its magnetic structure along with its lattice structure.
