Rapid and complete switching between the N6 and the N5O donor set induced by changing the metal oxidation state has been observed for a new structural motif based on a ruthenium(II) polypyridyl complex.

The effect of adsorption acid gases CO 2 , SO and 3 on the electron accepting ability cations surface calcium oxide was studied by low-temperature IR spectroscopy adsorbed CO. It is shown that formation carbonate, sulfite sulfate anions in layer leads to appearance Lewis sites, strength which, estimated shift vibration frequency molecules associated with them, increases appropriate order, appro...

We introduce several series of novel ZE-isomerism descriptors derived directly from two-dimensional molecular topology. These descriptors make use of a quantity named ZE-isomerism correction, which is added to the vertex degrees of atoms connected by double bonds in Z and E configurations. This approach is similar to the one described previously for topological chirality descriptors (Golbraikh,...

BACKGROUND Heterotaxy has been demonstrated to reduce survival. There are several different subgroups of patients, however, and no single study has had a large number of patients and analyzed survival across the different subgroups such as patients born in different eras, patients with right and left isomerism, and patients with biventricular or functionally univentricular hearts. This study po...

So-called "heterotaxy" is a laterality defect characterized by isomerism of the thoracic organs and random arrangement of the abdominal organs. These findings go beyond anatomic curiosity and have functional implications. It is, thus, of the utmost importance to be able to properly identify these findings. Radiologic studies can be invaluable in determining anomalies in the central nervous, pul...

The most complex combinations of congenital cardiac malformations are found in the setting of bodily isomerism. The question remains, however, as to whether evidence of cardiac isomerism is always to be found in the setting of bodily isomerism, also known as "heterotaxy." We have previously shown that, when assessed on the basis of the extent of the pectinate muscles relative to the atrioventri...
