Copper-containing enzymes catalyze a broad spectrum of redox reactions. Thiocyanate dehydrogenase (TcDH) from Thioalkalivibrio paradoxus Arh1 enables the bacterium to use thiocyanate as unique source energy and nitrogen. Oxidation takes place in trinuclear copper center TcDH with peculiar organization. Despite crystal structure being established, role some residues enzyme active site has yet be...

Ion-associate complexes of Itopride hydrochloride with zinc(II) thiocyanate, sodium cobaltinitrite and ammonium reineckate are precipitated. The solubility of the ion associates at the optimum pH and ionic strength values have been examined. Saturated solutions were prepared at different temperatures ( 25 – 60C ) under the optimum precipitation conditions and the metal ion contents ( zinc, chro...

a kinetic spectrophotometric method for rapid measurement of thiocyanate in serum, urine and sewage water with no need for removed of interfering substances in described. the method is based on the inhibitory effect of thiocyanate on the oxidation of pyrogallol red by bromated and nitrite which is monitored at 467 nm. the variables affecting the rate of the reaction were investigated and the op...

Polypyrrole (PPy/Cl) and polyaniline (PAni/Cl) synthesized chemically onto sawdust (SD)was used for removal of thiocyanate (SCN-) ions from aqueous solutions. The effect of someimportant parameters such as pH, initial concentration, sorbent dosage, and contact time onuptake of SCN- was investigated. PPy/SD was found to be much more effective sorbent thanPAni/SD for uptake SCN- from aqueous solu...

In the title compound, {(NH(4))[Cd(NCS)(3)]·C(12)H(24)O(6)}(n), the Cd(2+) ion, the ammonium cation, one of the SCN(-) ligands and the macrocycle are located on mirror planes. The thiocyanate anions act as bridging ligands between the Cd(II) ions, leading to a polymeric chain arrangement extending along [001] around a twofold screw axis. The ammonium ions are contained within the bowl of the ma...

Reaction of cobalt(ii) and nickel(ii) thiocyanate with ethylisonicotinate leads to the formation of [M(NCS)2(ethylisonicotinate)2]n with M = Co (2-Co) and M = Ni (2-Ni), which can also be obtained by thermal decomposition of M(NCS)2(ethylisonicotinate)4 (M = Co (1-Co), Ni (1-Ni)). The crystal structure of 2-Ni was determined by single crystal X-ray diffraction. The Ni(ii) cations are octahedral...

Autosomal dominant myotonia congenita is an inherited disorder of skeletal muscle caused by mutations in a voltage-gated Cl- channel gene (CLCN1, 7q35). Here, we report that a mutation predicting the substitution of Gly 230 by glutamic acid (G230E) between segments D3 and D4 dramatically alters the pore properties of a recombinant human muscle Cl- channel (hCIC-1) expressed in a mammalian cell ...

Carboxyhaemoglobin and plasma thiocyanate concentrations were measured in 79 non-smokers and 360 cigarette smokers. The mean levels were 0.73% and 7.09% carboxyhaemoglobin and 40 . 2 and 133 . 8 mumol thiocyanate/1 plasma respectively. With 1 . 6% carboxyhaemoglobin and 73 . 0 mumol thiocyanate/1 plasma as critical values the concentrations of carboxyhaemoglobin in 96.6% of subjects and of thio...
