A 22 month old male infant with isomerism of the right atrial appendages (associated with a complete atrioventricular septal defect, double outlet right ventricle, and pulmonary valve stenosis) died from pneumococcal septicaemia after a 36 hour illness. He had not been given penicillin prophylaxis. Asplenia was confirmed at necropsy. In a survey of 50 paediatric cardiologists in the United King...

Isomerism or Heterotaxy syndromes are rare multifaceted congenital anomalies with multi-system involvement. Grouped under the broad category of Situs Ambiguous defects, these often pose diagnostic difficulties due to their varied and confusing anatomy. Since patients rarely survive into adulthood due to cardiovascular complications, the etiology and natural history of such conditions are not fu...

We present an isomerism strategy to study the substitution position of perylene diimides on performances aggregation-induced emission (AIE) and two-photon absorption (2PA). Interestingly, enhanced AIE 2PA have been achieved.

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.

An unprecedented example of supramolecular isomerism based on 2D hydrogen-bonded multi-component networks that leads to the preparation of different photoproducts via a topochemical transformation is reported.
