The title compound, [CuPd(CN)4(C4H12N2)2]n, consists of one-dimensional chains. The Cu and Pd atoms are both located on centers of symmetry in an alternating array of [Cu(N-Eten)2]2+ (N-Eten = N-ethyl­ethylenediamine) and [Pd(CN)4]2- units. The Pd-C distances of 1.991 (3) and 1.992 (3) Å are inter­mediate values compared with the analogous NiII and PtII complexes [Akitsu & Einaga (2007). Inorg. Chim. Acta, 360, 497-505]. Due to Jahn-Teller effects, the axial Cu-N bond distance of 2.548 (2) Å is noticeably longer than the equatorial distances [Cu-NH2 = 2.007 (2) and Cu-NHC2H5 = 2.050 (2) Å]. There are interchain hybrogen bonds, with N(-H)...N = 3.099(4) Å.

An equimolar mixture of stearic acid (octadecanoic acid) and nicotinamide (3-pyridinecarboxamide) in acetone yields crystals of a 1:1 complex, C18H36O2·C6H6N2O. In this structure, the 1:1 complex forms a dimer through hydrogen bonds between the amide groups, thus forming a lamellar structure. The alkyl chain of stearic acid has an all-trans conformation.

The structure of AKR1C21 holoenzyme was determined at 1.8 Å resolution. A model describing the interaction between AKR1C21 and steroid substrates is proposed that explains the bifunctionality of the enzyme.

The structure of the Y224D mutant of mouse 3(17)[alpha]-hydroxysteroid dehydrogenase revealed that the mutation resulted in a change in the conformation of the flexible loop B. This loop is a unique feature of the active-site architecture of the wild type and is formed by the side chains of Tyr224 and Trp227.

The role of the double-hydrophilic block copolymers (poly(ethylene glycol)-block-poly(methacrylic acid)) on the morphogenesis of calcium carbonate (CaCO3) was studied by applying contrast variation small-angle neutron scattering (SANS). The scattering function for ternary systems can be expressed by only partial scattering functions of the single species, as derived on the assumption of incompressibility. We demonstrate the feasibility of this formula by means of contrast variation SANS, and the decomposed partial scattering functions give their detailed information. Especially the partial scattering function of polymer shows a Q-2.7 monotonic slope at low Q (0.002 Å < Q < 0.02 Å; Q is the modulus of the scattering vector), which is a clear evidence that the distribution of the polymer in CaCO3 has a mass fractal dimension. This result is confirmed by time-resolved SANS experiments with CaCO3 contrast, where a Q-2.5 slope was observed at the early stage of the reaction in the same Q range.

A presequence peptide derived from rat aldehyde dehydrogenase was tethered to the cytosolic domain of rat Tom20 protein via an intermolecular disulfide bond. Two crystal forms were obtained with different linker designs and diffracted to 2.1 and 1.9 Å.
