In the title polymer, {[La(2)(C(4)H(4)O(6))(3)(H(2)O)(3)]·2H(2)O}(n), two symmetry-independent La(III) ions are nine-coordinated and display a distorted monocapped square-anti-prismatic geometry. One is coordinated by seven O atoms from four tartrate ligands and two water mol-ecules, the other by eight O atoms from five tartrate ligands and one water mol-ecule. The three tartrate ligands in the...

In the title compound, C(12)H(15)ClNO(+)·C(4)H(5)O(6) (-), the cyclo-hexa-none ring adopts a chair conformation. The benzene ring is significantly twisted so that it is in an almost perpendicular position to the C-N bond with a C(Ar)-C(Ar)-C-N torsion angle of -96.5 (5)°. Intermolecular N-H⋯O and O-H⋯O hydrogen bonds are observed in the crystal structure.

Cesium chloride density gradients are frequently used for virus concentration or purification in the preparation of human feces for examination by electron microscopy, Disruption of some of the fecal viruses occurs if they are pelleted from the density gradient in an additional concentration step. This report highlights an important limitation imposed by the use of cesium chloride as a density ...

In the title compound, 2C(3)H(7)N(6) (+)·C(4)H(4)O(6) (2-)·2H(2)O, in which the complete anion is generated by crystallographic twofold symmetry, there are O-H⋯O, N-H⋯O and N-H⋯N hydrogen-bonding inter-actions between neighbouring moieties, forming layers parallel to the bc plane. In addition, π-π contacts [centroid-centroid distance = 3.6541 (9) Å] between the six-membered rings of the melamin...

Mycelial pellets of Trametes versicolor, grown at initial glucose and ammonium tartrate concentrations of 10 g/l (56 mM) and 0.442 g/l (2.4 mM) respectively, decolorized successive additions of the same dye (Amaranth) and of different dyes and dye mixtures. Decoloration commenced by Day 3 and all dyes were decolorized at high rates during the next 12 days. Glucose was consumed at a steady rate ...

The isolation and identification of a new sub-genus I Salmonella is described. The complete antigenic formula is 3,10:z29:enx; the serotype has been named Salmonella everleigh. The strain is atypical in that it ferments salicin, produces indole, and fails to produce acid in tartrate media.

Although pentolinium tartrate is widely used in the treatment of hypertension, there are no reports available regarding some of its cardiovascular effects and its influence on water and electrolyte excretion. The results of the present study indicate that this drug is of value in reducing the mean arterial blood pressure in hypertensive patients. However, the data also indicate the necessity fo...
