The molecular structure of 1a and 2 were studied by X-ray diffraction and compared to density-functional-theory

(DFT) calculations. The gauge-including atomic orbital (CIAO) method for calculating H-1 and C-13 NMR nuclear magnetic shielding tensors at the DFT method with 6-31+G* basis set were applied to the compounds 1a and 2. Additionally, thermodynamic properties of the cyclization of the compound 3 to these compounds (1a, 1b, 1c, 4) were investigated by theoretical calculations. These Selleckchem ALK inhibitor theoretical calculations was shown that the compound 1a was readily formed and was the most stable one. Tautomeric forms of the compound 1a were optimized at the same methods and basis set. The calculated relative Gibbs free energies of the

tautomeric forms of 1a were used to estimate the equilibrium constants. It was shown that the 1a was the most stable than tautomer of 1b and 1c in the gas phase. (C) 2012 BVD-523 mw Elsevier B.V. All rights reserved.”
“Study Design. Retrospective study.\n\nObjective. To evaluate clinical outcomes of dual growing rod (GR) technique in treating children with congenital scoliosis (CS).\n\nSummary of Background Data. Published reports on the dual GR technique results of early-onset scoliosis demonstrate it to be safe and effective. However, the use of GR in congenital spinal deformities is controversial, and there have been no reports on the results and complications of dual GR technique for CS with large series of patients.\n\nMethods. During 2004 to 2009, a total of 30 patients with CS underwent dual GR procedures. Of the 159 total procedures conducted within the treatment period, 125 were lengthenings with an average of 4.2 lengthenings per patient. Five patients with severe rigid deformity or kyphosis had an osteotomy at apex vertebra with short segmental fusion. The analysis included age at initial surgery and final fusion (if applicable),

number and frequency of lengthenings, and BMS-345541 clinical trial complications. Radiographical evaluation was conducted.\n\nResults. The mean scoliosis improved from 72.3 degrees to 34.9 degrees after initial surgery and was 35.2 degrees at the last follow-up or after final fusion. T1-S1 length increased from 25.42 to 29.03 cm after initial surgery and to 33.32 cm at last follow-up or after final fusion with an average T1-S1 length increase of 1.49 cm per year. The space available for lung ratio in patients with thoracic curves improved from 0.84 to 0.96 at the latest follow-up. Three patients reached final fusion. Complications occurred in 7 of the 30 patients, and they had a total of 13 complications.\n\nConclusion. The dual GR technique is safe and effective in the treatment of selected cases of long, complex CS. It maintains correction achieved at initial surgery while allowing spinal growth to continue. And it has an acceptable rate of complications.
