The title compound, Na(3)[NpO(4)(OH)(2)]·2H(2)O, contains distorted tetra-gonal-bipyramidal centrosymmetric [NpO(4)(OH)(2)](3-) complex anions. The Np-O distances are 1.8975 (7) and 1.8891 (7) Å in the NpO(4) group and 2.3451 (7) Å to the OH group. Both Na atoms (one in a general position, the second in a special position on an inversion centre) have a distorted octahedral oxygen environment.

N EW IMPROVED histochemical technics for detecting glycogen in tissues justify reinvestigation of the distribution of glycogen in human blood cells. Histochemical methods permit more precise observations on the localization of glycogen within single cells of different types than are obtained by macrochemical analyses. Most investigators have claimed that glycogen is present in only certain type...

Phytochemical reinvestigation of the roots and rhizomes of Veratrum taliense yield three known (solanidine, veramiline-3-0-~D-glucopyranoside and stenophylline B-3-0-~D-glucopyranoside) and two novel steroidal alkaloids. The structures of the new compounds have been established by a combination of spectroscopic methods as 3angeloylzygadenine-I3-N-oxide and (20S,25S)-22,26-epiminocholesta-5,22-d...

Bone marrow examination of a patient chromosome in the previously aneuploid with a myeloproliferative disorder recell line (45,XX,-6,-22,+Ph’). This case vealed monosomy for chromosome No. 6 differs from those previously published in (45,XX,-6). Two months later, during that the Ph’ chromosome appeared de blastic crisis, reinvestigation of the bone novo during the development of frank marrow sh...

In previous reports from this laboratory investigations of the specific esterase activity of trypsin (1) and of the detailed kinetics of the hydrolysis of specific substrates by chymotrypsin and by carboxypeptidsse have been reported (2, 3). In the present paper a reinvestigation of the kinetics of the action of trypsin on benzoyl-L-argininamide and the results of kinetic studies of the action ...

A reinvestigation of a Fijian collection of Cacospongia mycofijiensis has yielded the known mycothiazole and a novel heterocyclic, CTP-431 (1). Its structure including absolute configuration as 8R,9R,10S,13S was established using NMR data, calculated DFT (13)C chemical shifts and results from X-ray crystallography. It is possible that the tricyclic skeleton of CTP-431 (1) is biosynthetically re...
