PURPOSE The authors' aim was to compare bowel function in patients who had undergone repair of a low anorectal malformation with that of normal healthy children. METHODS The bowel function of 40 patients (29 boys, 11 girls; median age, 7; range, 3 to 13) with low anorectal malformations was evaluated by a multivariate scoring method based on a(More)
BACKGROUND Constipation is one of the most important functional sequelae in patients with anorectal malformations. The cause of this motility disorder is unknown. AIM The purpose of this study was to assess total colonic transit time (TCT) and segmental colonic transit time (SCT) in patients with anorectal malformations. METHOD Ninety patients with(More)
Rotational isomerization of acetic acid (CH3COOH) is studied in Ar, Kr, and Xe matrices. The light-induced trans-->cis reaction is promoted using resonant excitation of a number of modes in the 3500-7000 cm(-1) region, and the quantum yields for this process are measured for various acetic acid isotopologues and matrix materials. For excitation of acetic(More)
The HArF molecule can occupy in solid Ar thermally unstable and stable configurations, and their microscopic structure is not understood at the moment. We present additional experimental results on the formation of two HArF configurations and analyze them with emphasis on possible reactions of the unstable configuration with matrix vacancies to form the(More)
The trans and cis forms of formic acid (HCOOH) in solid argon favor essentially different photodissociation (193 nm) products, H2O + CO and H2 + CO2, respectively. The branching ratio of these channels differs between the two conformers by a factor of >10. The observed selective photodissociation features conformational memory when the transition state of a(More)
