[Treatment strategy and prognosis analysis in children with type I esophageal atresia].

Objective: To analyze the postoperative short-term and long-term outcomes in the management of type I esophageal atresia, and to explore the ideal operative strategy.

Methods: Clinical data of 22 patients with type I esophageal atresia treated from January 2005 to September 2012 were retrospectively reviewed. Of 22 patients, 6 patients gave up the treatment.

[Long-term outcomes and nutrition evaluation in children with total colonic aganglionosis].

Objective: To examine the long-term outcomes of total colonic aganglionosis (TCA) and to evaluate their nutritional status.

Methods: Eleven pediatric patients treated for TCA between January 1999 and December 2010 were included in the study and followed up. Physical measurements including height, weight and laboratory tests were assessed.

Raman spectroscopy with graphenated anodized aluminum oxide substrates.

We measured the Raman scattering of graphene deposited nanohole arrays. As the sample was azimuthally rotated, periodicities of 7.5 degrees and 5 degrees were revealed for the 2700 cm(-1) and 1600 cm(-1) Raman lines of graphene, respectively.

Hammett equation and generalized Pauling's electronegativity equation.

Substituent interaction energy (SIE) was defined as the energy change of the isodesmic reaction X-spacer-Y + H-spacer-H --> X-spacer-H + H-spacer-Y. It was found that this SIE followed a simple equation, SIE(X,Y) = -ksigma(X)sigma(Y), where k was a constant dependent on the system and sigma was a certain scale of electronic substituent constant. It was demonstrated that the equation was applicable to disubstituted bicyclo[2.

First-principle predictions of absolute pKa's of organic acids in dimethyl sulfoxide solution.

MP2/6-311++G(d,p) and B3LYP/6-311++G(2df,p) methods were found to be able to predict the gas-phase acidities of various organic acids with a precision of 2.2 and 2.3 kcal/mol.
