A cobalt cluster-based triple-stranded helicate, Co8(PDA)6(PTA)3(DMF)3(H2O)3 () (PDA = 2,6-pyridinedicarboxylate, PTA = benzene-1,3-dicarboxylate, DMF = dimethylformamide) was successfully synthesized and fully characterized. Complex can be used as a supramolecular building block in constructing a higher-order helix-of-helix structure, [Co8(PDA)6(PTA)3(DMF)2(H2O)4-0.51(Co(OHn)2)] (n = 1 or 2) ().

The synthesis of the cationic gold(i) complexes [Au(C[triple bond, length as m-dash]CC5H4N)(CH3-PTA)]X (X = I, 1; X = OTf, 4), [Au(C[triple bond, length as m-dash]CC5H4N-CH3)(PTA)]X (X = I, 2; X = OTf = 5; PTA = 1,3,5-triaza-7-phosphatricyclo[3.3.1.13.7]decane) and [Au(C[triple bond, length as m-dash]CC5H4N-CH3)(DAPTA)]X (X = I, 3; X = OTf = 6, DAPTA = 3,7-diacetyl-1,3,7-triaza-5-phosphabicyclo...

Anomalous conotruncal cardiac morphology and facial dysmorphology have been associated with neural crest-pharyngeal arch abnormalities. To assess these associations, 20 patients 3 to 18 years old with tetralogy of Fallot (TOF) or persistent truncus arteriosus (PTA) were evaluated by cardiologic, facial dysmorphic, and cephalometric criteria. The average number of facial abnormalities of neural ...

In the cardiac clinic of the Hospital for Sick Children, Toronto, a 6-year-old girl with an auricular septal defect was found to have a monozygotic twin in whom the heart was normal. Instances of congenital heart disease in both of monozygotic twins have been reported by several authors. Smith (1929) observed a patent ductus arteriosus in both of twin boys of similar general appearance, size, a...

With the use of a two-dimensional range-gated pulsed-Doppler ultrasound system, Doppler examinations of the aorta and cerebral arteries were performed in 20 normal newborn infants and in 54 infants with various forms of congenital heart disease (i.e. patent ductus arteriosus, coarctation of the aorta, critical aortic stenosis, pulmonary atresia, truncus arteriosus). In the cerebral artery Doppl...

OBJECTIVE One and one half ventricle repair is a surgical option for congenital cardiac anomalies characterised by right ventricle (RV) hypoplasia and/or dysplasia. METHODS From March 1994 to March 2001, eight patients (mean age 9.1 years, range 7 months to 35 years) with hypoplastic and/or dysplastic RV underwent correction of their intracardiac anomaly in association with a BCPS (one and on...
