In the title compound, C(15)H(15)N(3)Ox3H(2)O, two of the three water molecules exhibit disorder. The molecular components are linked into a three-dimensional framework by a combination of N-H...O, O-H...N and O-H...O hydrogen bonds.

The absolute configuration of the octa-hedral fac-CoN(3)O(3) title complex, [Co(C(5)H(8)NO(2))(3)]·3H(2)O, has been determined by single-crystal X-ray analysis. A three-dimensional network of hydrogen bonds is observed between the proline carboxyl-ate groups and the three uncoordinated water mol-ecules.

Confocal Raman spectroscopy is applied to identify ferroelectric domain structure sensitive phonon modes in potassium titanyl phosphate. Therefore, polarization-dependent measurements in various scattering configurations have been performed to characterize the fundamental Raman spectra of the material. The obtained spectra are discussed qualitatively based on an internal mode assignment. In the...

Streptococcus bovis JB1 cells were able to transport serine, threonine, or alanine, but only when they were incubated in sodium buffers. If glucose-energized cells were washed in potassium phosphate and suspended in potassium phosphate buffer, there was no detectable uptake. Cells deenergized with 2-deoxyglucose and incubated in sodium phosphate buffer were still able to transport serine, and t...

An alkalophilic bacterium, Bacillus cereus produced an extracellular alkaline protease, which was found to be active at high temperature and pH range, suitable for commercial laundry detergents. B. cereus protease was partitioned in different aqueous two-phase systems such as PEG/dextran, PEG/potassium phosphate, PEG/sodium citrate, PEG/magnesium sulphate and PEG/sodium dihydrogen phosphate and...

Coincident with the drop in blood sugar produced by insulin, there occurs a marked drop in the inorganic phosphate and potassium in the blood serum and urine. This was shown by Harrop and Benedict in 1923 (1, 2) and by Briggs, Koechig, Doisy, and Weber (3). Kerr (4) showed also that the potassium that disappeared did not enter the corpuscles. Because an increased intake of carbohydrate will pro...

OBJECTIVE To review the physiology and cardiovascular effects of the commonly used intravenous electrolytes. DATA SOURCES Abstracts, articles and published reviews of studies reported from 1966 to 2000 and identified through a MEDLINE search on cardiac arrhythmias and electrolytes. SUMMARY OF REVIEW While isotonic saline solutions are used to improve the haemodynamic status in critically il...

Hypertensive cardiovascular damage is accelerated by salt loading but counteracted by dietary potassium supplementation. We suggested recently that antioxidant actions of potassium contribute to protection against salt-induced cardiac dysfunction. Therefore, we examined whether potassium supplementation ameliorated cuff-induced vascular injury in salt-sensitive hypertension via suppression of o...

In this study, after specifying theoretical reaction conditions required for the chemical reaction, potassium pentaborate (KB5) was synthesized from dihydrogen phosphate ( $${\text{KH}}_{2} {\text{PO}}_{4}$$ ) solution and raw colemanite $${\text{Ca}}_{2} {\text{B}}_{6} {\text{O}}_{{11}} \cdot 5{\text{H}}_{2} {\text{O}}$$ ore. The slow evaporation method used at 25 °C. effect of time (6–18 h) o...
