OBJECTIVE To report our experiences in the prenatal diagnosis of atrial isomerism and postnatal outcomes. METHODS A total of 80 fetuses prenatally diagnosed with atrial isomerism were retrospectively analyzed between 1999 and 2011 at a single institution. RESULTS Of 43 fetuses with prenatally diagnosed right atrial isomerism (RAI), 40 cases were analyzed. The diagnostic accuracy was 93%. Th...

Access to the new complex [TpCr(CN)3]- enables isolation of two metastable linkage isomers of a face-centered cubic cluster, [Tp8(H2O)6Cu6Cr8(CN)24]4+, both exhibiting an S=15 ground state.

The seminal discovery of light-induced changes in transition-metal nitrosyl complexes in the late 1970s and their identification as metastable linkage isomers almost 20 years after the initial discoveries have in recent years motivated a plethora of experimental and theoretical studies. They have raised the question of whether the linkage isomers play a role in the many crucial biological proce...

At present there is no reliable method of recognising atrial isomerism by two dimensional echocardiography. We therefore used two dimensional echocardiography to examine 158 patients including 25 with atrial isomerism and four with situs inversus. Particular attention was paid to the short and long axis subcostal scans of the abdomen. Using the position of the inferior vena cava and the aorta w...

Treatment of [HNBu3]3[Mo(V)(CN)8] with manganese(II) p-toluenesulfonate in N,N'-dimethylformamide (DMF) affords {[Mn(II)(DMF)4]3[Mo(V)(CN)8]2}n (1) as a two-dimensional network. The structure of 1 consists of [cis-Mn(II)(DMF)4(mu-NC)2]2+ and [trans-Mn(II)(DMF)4(mu-NC)2]2+ units that are linked via cyanides to three-connected [Mo(V)(CN)5(mu-CN)3]3- centers in a 4:2:6 ratio, forming 12-membered r...

Bond-stretch isomerism is predicted not to occur in the parent compound Si4H6 and the substituted 1,3-di-tert-butyl derivative, although the existence of bond-stretch isomerism in the 1,3-dimethyl derivative is a possibility. Bulky bridgehead moieties induce a preference for a short Si−Si bridge bond, while a longer bridge bond length (2.840 Å at the MP2/6-31G(d,p) level) is predicted for the u...

Two-quasiparticle K58 isomeric states in the A;130 and 180 regions are studied with configurationconstrained calculations of potential-energy surfaces. Strong shape-polarization effects due to the two quasiparticles are found. In particular, the nuclei Pb,Hg, and Te can be polarized from ground-state spherical or oblate shapes to prolate shapes, indicating a combination of K isomerism and shape...
