A study of the inhibition of the growth of Streptococcus cremoris 972 by the enzyme lactoperoxidase has shown, in agreement with previous investigations, that the inhibition requires a source of both peroxide and thiocyanate. The thiocyanate may play more than one role. It stabilizes the very dilute solutions of lactoperoxidase employed in these studies, and its oxidation products may be involv...

OBJECTIVES Hypothyroidism in utero leading to mental retardation is highly prevalent and recurrent in developing countries where iodine deficiency and thiocyanate overload are combined. So, to explore and identify human population's risks for developing iodine deficiency disorders and their endemicity in Western Cameroon, with the aim to prevent this deficiency and to fight again it, urinary io...

a carbon ionic liquid electrode (cile) modified with tio2-fe nanoparticles was constructed by incorporating tio2-fe nanoparticles into the paste matrix. under the optimized experimental conditions, using differential pulse voltammetry (dpv), the oxidation of thiocyanate and oxalate were occurred at potentials of 0.740 v and 1.010 v, respectively, at the surface of the modified electrode. observi...

To evaluate the susceptibility of steels to hydrogen embrittlement, it must be charged and have its content controlled before any mechanical testing. In this study, permeation tests an iron sheet were performed during potentiostatic charging in various solutions containing ammonium thiocyanate obtain a guideline for efficient wide range contents. As polarization potential shifted negative direc...

Solvation of the thiocyanate ion in three different deep eutectic solvents (DES) was investigated by linear FTIR spectroscopy, and Two Dimensional IR spectroscopy. Linear infrared spectroscopy reveals that the thiocyanate ion forms a hydrogen bond through its sulphur atom, while its nitrile end remains free. Photon-echo vibrational spectroscopy shows that the thiocyanate has a frequency-frequen...

The binding of (RS)-alpha-[3H]amino-3-hydroxy-5-methylisoxazole-4-propionic acid ([3H]AMPA), a selective ligand for non-N-methyl-D-aspartate excitatory amino acid receptors, was investigated in rat brain using an autoradiographic receptor binding technique. [3H]AMPA binding sites were widely distributed throughout the rat central nervous system, and the rank order of potency of displacers of [3...

The Basin Hopping search method is used to find the global minima (GM) and map the energy landscapes of thiocyanate-water clusters, (SCN)(H2O)n with 3–50 water molecules, with empirical potentials describing the ion-water and water-water interactions. (It should be noted that beyond n = 23, the lowest energy structures were only found in 1 out of 8 searches so they are unlikely to be the true G...

The present interest in the determination of thiocyanate in serum, following the injection or ingestion of its salts, is twofold. First, in order to control hypertension by administering thiocyanate, the dosage must be regulated by frequently checking serum levels, as pointed out by Barker (1) and Wald, Lindberg, and Barker (2). Secondly, the determination of extracellular fluid, as originally ...

The biochemical and toxicological effects of occupational and dietary exposure of humans to cyanide poisoning from large-scale cassava processing and ingestion of cassava foods were investigated using spectrophotometric and enzymatic methods. Analysis of urinary and serum thiocyanate (cyanide metabolite) from workers in cassava processing industries, who were 'frequent' [those who eat cassava f...

A survey of neurological abnormalities in two Nigerian villages preselected for their differing consumption of cassava has shown that a degenerative neuropathy occurs with relatively high frequency in the village (Ososa) where cassava consumption was high.It is suggested that eating cassava results in exposure to cyanide, as shown by a raised plasma thiocyanate level, and that the latter, toget...
