Ivemark syndrome is classified as a heterotaxy disorder or a laterality disorder. These terms refer to the failure of the internal organs of the chest and abdomen to be arranged in the proper location within the body. It is characterized by the absence (asplenia) or underdevelopment (hypoplasia) of the spleen, malformations of the heart and the abnormal arrangement of the internal organs of the...

A bis-μ-amidoximato-bridged cobalt(III) dimer obtained with a new tetrapodal ligand possesses interesting structural parameters as a consequence of intramolecular hydrogen bonding intentionally built into the complex. Its synthesis and properties are described. The new ligand type combines attributes of two previously described ligand classes: It binds a metal ion in a tetrapodal pentadentate f...

Three cases of twins conjoined across the chest were examined. In one set, one twin showed right atrial isomerism and the other showed the usual atrial arrangement. The other two sets showed the usual atrial arrangement in both twins. The associated cardiac anomalies were diverse, ranging from atrioventricular septal defects to absent atrioventricular connections. Sequential segmental analysis ...

The isomerism of zinc complex [Zn(L)2]2+ with tridentate ligand L having acetamide and pyridine groups on each side the central amino- nitrogen atom has been investigated by DFT calculations, liquid state NMR single-crystal X-ray diffraction. was used for obtaining ensembles low-energy conformers calculation parameters all conformers. For generated [Zn(L)2]2+, Mean Absolute Error [MAE(conf)] te...

Aims: Evidence is emerging that, in the setting of isomerism, atrial and bronchial arrangement are not always concordant, nor these patterns harmonious with abdominal organs. We aimed to evaluate concordance between features a cohort patients cardiac malformations known seeking determine whether it was feasible assess complexity on this basis, regard taking note potential value as opposed appen...

Conformational isomerism of a ball-shaped cyclophane of cyclen was studied using NMR and computational methods with the most notable conformer containing a highly symmetric cyclic benzene tetramer.
