A new germanium(II) phosphate, sodium tetra-germanium tris-(phosphate), Na[Ge(4)(PO(4))(3)], has been synthesized by a solid-state reaction. The compound is isotypic with A[Sn(4)(PO(4))(3)] (A = Na, K, NH(4)). It features a [Ge(4)(PO(4))(3)](-) framework made up of GeO(3) pyramids and PO(4) tetra-hedra, which are linked by shared corners, yielding a three-dimensional structure. The crystal stud...

Cells of the red marine alga, Porphyra perforata, accumulate potassium and exclude sodium, chloride, and calcium. Various metabolic inhibitors including dinitrophenol, anoxia, and p-chloromercuribenzoate partially abolish the cells' ability to retain potassium and exclude sodium. Iodoacetate induces potassium loss only in the dark; reduced sulfur compounds offer protection against the effects o...

A series of novel 2-methyl-3-substituted quinazolin-4-(3H)-ones have been synthesized by treating (2-methyl-4-oxo-3H-quinazolin-3-yl)dithiocarbamic acid methyl ester with different amines, the starting material dithiocarbamate was synthesized from anthranilic acid. The compounds synthesized were investigated for analgesic, anti-inflammatory and antibacterial activities. All the test compounds e...

Replacement of individual P-loop residues with cysteines in rat skeletal muscle Na+ channels (SkM1) caused an increased sensitivity to current blockade by Cd2+ thus allowing detection of residues lining the pore. Simultaneous replacement of two residues in distinct P-loops created channels with enhanced and reduced sensitivity to Cd2+ block relative to the individual single mutants, suggesting ...

In a previous paper (2) it was demonstrated mat nitrogen mustards caused a considerable decrease in the viscosity of sodium thymonucleate solutions. The present work was undertaken to determine whether this effect was due to an interaction of the nitrogen mustards with thymonucleate or some of its constituents. An interaction between nitrogen mustards and thymonucleate was demonstrated but coul...

Abstract Dissolved and particulate sodium, magnesium calcium are analyzed in ice cores to determine past changes sea extent, terrestrial dust variability atmospheric aerosol transport efficiency. They also used date if annual layers visible. Multiple methods have been developed analyze these important compounds cores. Continuous flow analysis (CFA) is implemented with instruments that sample th...

The article considers the classification of organoarsenic compounds and types their production; application computer simulation in chemical-technological processes. reaction for obtaining sodium 2-oxido(phenyl)arsoryl acetate was simulated, kinetic curves were obtained analyzed; parameters are set to increase yield product

Mn-substitution NASICON-type Na 3+x Mn x V 2-x (PO 4 ) 3 compounds have been extensively studied as a desirable cathode material for sodium-ion batteries (SIBs), due to their higher operating voltage, low cost and weak biological toxicity compared...

Acceptable palatability of an oral dosage form is crucial to patient compliance. Excipients can be utilised within a formulation mask the bitterness drug. One such category bitter-blockers. This term used inconsistently literature and has historically been describe any additive which alters taste unpleasant compound. review defines bitter-blocker as compound interacts with molecular pathway at ...
