The microstructure of the heart has a major impact on its mechanical and electrical properties. Diffusion tensor magnetic resonance imaging (DTI) exploits the anisotropic restriction of water diffusion in the myocardium to resolve its microstructure. Recent advances in the field have included the development of acceleration-compensated diffusion-encoded sequences, the investigation of sheet dynamics, and the development of highly accelerated techniques to enable whole heart coverage. Translational studies have demonstrated the utility of DTI in heart failure and other cardiomyopathies. While DTI of the heart remains investigational, ongoing advances in the field will soon allow the technique to be performed reliably and quickly in appropriate clinical scenarios.

Blends of dodecylbenzene sulfonic acid-doped polyaniline (PANI-DBSA) with either polyacrylonitrile copolymer (PAN) or polystyrene (PS) were solution cast. The investigation focused on the interaction between the components, the morphology and the resulting electrical conductivity of blends. The results showed that with the same PANI-DBSA content the conductivity of PANI-DBSA/PAN was higher than that of PANI-DBSA/PS. PANI-DBSA was dispersed uniformly in the PAN matrix and its cluster size was rather smaller than in the PS matrix. This is attributed to hydrogen bonding between the carbonyl groups in PAN and the imine groups in PANI, which should lead to better compatibility between PANI-DBSA and PAN.

(�)-2,4-cis-4-Aminoflavan obtained by reduction of 4-oximinoflavan has been resolved into enantiomeric forms by fractional crystallization of its amine salts with (+)-camphor-10-sulphonic acid and with (-)-di-O-benzoyltartaric acid. The pairs of diastereoisomeric salts thus separated were converted into (+)- and (-)-2,4-cis-4-aminoflavan hydrochlorides, from which the free bases and the optically active N-acetyl and N-benzoyl derivatives were prepared. N.m.r. data unequivocally establish the 2,4-cis configuration of all these 4-substituted flavan derivatives. 3-Aminoflavanone prepared by the Neber rearrangement of 4-oximinoflavan, and also by controlled catalytic hydrogenation of 3-oximinoflavanone, is shown from N.M.R. data on suitable derivatives to have the 2,3-trans configuration.
