Hypothiocyanite is the anion [OSCN]− and the conjugate base of hypothiocyanous acid (HOSCN). It is an organic compound part of the thiocyanates as it contains the functional group SCN. It is formed when an oxygen is singly bonded to the thiocyanate group. Hypothiocyanous acid is a fairly weak acid; its dissociation constant is 5.3. Hypothiocyanite is formed by peroxidase catalysis of hydrogen peroxide and thiocyanate: H2O2 + SCN− → OSCN− + H2O Hypothiocyanite occurs naturally in the antimicrobial immune system of the human respiratory tract in a redox reaction catalyzed by the enzyme lactoperoxidase. It has been researched extensively for its capabilities as an alternative antibiotic as it is harmless to human body cells while being cytotoxic to bacteria. The exact processes for making hypothiocyanite have been patented as such an effective antimicrobial has many commercial applications. Lactoperoxidase-catalysed reactions yield short lived intermediary oxidation products of SCN−, ...

Evidence is accumulating to indicate that sulforaphane not only offers protection against chemically induced cancer in animal models (15, 17, 18) but also suppresses proliferation of cancer cells in culture as well as in vivo (20-29) . Studies have indicated that inhibitory effect of sulforaphane against proliferation of cultured cancer cells is attributable to cell cycle block as well as apoptosis induction (20-29) . A novel mechanism of chemoprevention by sulforaphane involving inhibition of histone deacetylase was also suggested recently (26). Our own work has revealed that sulforaphane treatment causes apoptosis in PC-3 human prostate cancer cells in association with activation of caspases (28). Despite these advances, however, the mechanism of sulforaphane-induced apoptosis remains poorly defined. For instance, the signaling pathways upstream of caspase activation in sulforaphane-induced cell death are not characterized. The present study provides experimental evidence to indicate that ...
Purpose : The anion conductance of the RPE basal membrane plays a key role in the active transport of Cl- between the subretinal space and choroid. Previously, we reported that exposure of isolated mouse RPE cells to thiocyanate (SCN-) evokes a large whole-cell current, suggesting that the RPE may contain a previously unknown anion channel. The purpose of this study was to characterize the biophysical and pharmacological properties of this channel in excised membrane patches as the next step towards determining its identity. Methods : RPE cells were freshly isolated from the eyecups of C57/B6 mice and placed in a constantly perfused recording chamber. Currents from excised outside-out patches of basal or apical membrane were recorded using the patch-clamp technique. The pipette solution contained 135 mM NMDG-Cl and the bath solution contained 140 mM NaCl or 140 mM NaSCN. The relative permeability (PSCN/PCl) was calculated using the GHK equation. Results : Replacement of external Cl- with SCN- ...

Hints: It works best to add the barium hydroxide to the ammonium thiocyanate. The ammonium thiocyanate is damp, tending to stick to the inside of the flask, making it more troublesome to transfer.. Discussion: Ba(OH)2*8H2O(s) + 2NH4SCN(s) ---, Ba(SCN)2 (aq)+ 2NH3(g)+ 10H2O(l). This reaction is entropically driven. Because the reaction occurs spontaneously, DG is negative. Because heat is absorbed by the reaction from the surroundings, DH is positive.. DS is positive because of the formation of ammonia gas and liquid water. The effect of increased entropy more than compensates for the positive enthalpy change. ...

Exposure of brown trout (Salmo trutta) in fresh water to 0.15 mmol l-1 external thiocyanate for 1 h resulted in a significant decrease in chlorine concentration in the branchial mitochondria-rich (MR) cells from 37 mmol l-1 to 22 mmol l-1. The intracellular sodium concentration in these cells decreased by a similar amount, whilst the intracellular phosphorus concentration increased significantly. In contrast to the MR cells, 0.15 mmol l-1 external thiocyanate had no effect on the intracellular ion concentrations in the pavement epithelial cells. Thiocyanate is known to inhibit chloride uptake in a number of freshwater animals and therefore these data suggest that it is only the MR cells that are involved in the uptake of Cl- in brown trout. ...
A novel electrode modified with silver nanoparticles was fabricated. It is found that the reducibility of silver nanoparticles is higher than for bulk silver by comparing a silver nanoparticles modified electrode with a silver micro-disk electrode. When SCN- was added, a new oxidation peak occurred and the anodic peak current of silver nanoparticles decreased. The new anodic peak current is proportional to the thiocyanate concentration in the range of 5.0×10-7~4.0×10-4 mol/L in pH 6.0 NaH2PO4-Na2HPO4 buffer solutions (PBS). The detection limit (S/N=3) is 4×10-8 mol/L. This method has been applied to the determination of saliva (smoker and non-smoker).

1. Experiments designed to show a specific antagonism between sodium thiocyanate and several narcotic agents have failed entirely to support the claims made by Bancroft and Reitzler that a marked decrease in anaesthesia and a marked increase in respiration is produced by the administration of sodium thiocyanate.. 2. A discussion of Bancrofts statement of the Claude Bernard theory of narcosis shows that Bancroft has not been able to demonstrate that coagulation (as the term is usually understood) always accompanies narcosis. This and other evidence which is so ably presented by Winterstein (22) (p. 357-60), and discussed more briefly by Henderson (15), leads us to reject a coagulation theory of narcosis. And this is true, even if we use the word "coagulation" with the Bancroft connotation.. ...
Section Seven BIOLOGICAL: PHENOLIC WASTE TREATMENT 25 FATE OF AMMONIA, THIOCYANATE, PHENOLICS, AND CYCLIC AROMATICS WITHIN ACTIVATED SLUDGE COKING PLANT WASTE TREATMENT Clifford R. Lange, Assistant Professor David E. Chambers, Graduate Student Department of Civil Engineering, Auburn University Auburn, Alabama 36849-5337 INTRODUCTION Coal distillation processes, such as coal gasification and coal coking produce complex wastewaters. The coking process involves the destructive distillation of coal in an anoxic environment. The volatile compounds released during the coking process are either condensed or scrubbed out in the gas main or primary coolers. Tar is decanted from the condensate and the remaining aqueous waste, known as the flushing liquor or weak ammonia liquor (WAL), is the major source of coking plant wastewater. Coke plant wastewaters include a complex mixture of organic and inorganic compounds, including: ammonia, cyanide, thiocyanate, monohydric phenols (70% phenol, 25% m-cresol, and ...
TY - JOUR. T1 - Organic light-emitting diodes with an electro-deposited copper(I) thiocyanate (CuSCN) hole-injection layer based on aqueous electrolyte. AU - Tsai, Chi Ting. AU - Gottam, Sandeep Reddy. AU - Kao, Po Ching. AU - Perng, Dung Ching. AU - Chu, Sheng Yuan. PY - 2019/10. Y1 - 2019/10. N2 - Copper(I) thiocyanate (CuSCN) has been drawing much attention in optoelectronics due to its exceptional optical and electrical properties, as well as its processing versatility. The first organic light-emitting diodes (OLEDs) integrated with electro-deposited CuSCN crystalline thin films based on aqueous electrolyte were fabricated. With precisely tuned deposition parameters, the CuSCN thin films with satisfactory surface roughness and sufficient grain density were realized. We found that the driving voltage (voltage at a current density of 100 mA/cm2) and turn-on voltage of OLEDs using CuSCN as the hole injection layer (HIL) can be reduced by 1.41 and 1.79 V, respectively, compared with devices ...
CASE REPORTS/ The case of a 39-year-old woman, who was found vomiting and confused 7 hr after ingesting 59 mL of nail polish remover (/SRP: probably nail glue remover not nail polish remover/) containing 99% acetonitrile (4 g/kg) /was reported/. About 12 hr after ingestion, she developed severe metabolic acidosis, seizures and shallow respiration. Eight hours after ingestion she had a whole blood cyanide level of 3130 ug/L. At 65 hr the serum cyanide level was 10 mg/L and thiocyanate was 120 mg/L, whereas at 77 hr they were 12 mg/L and 30 mg/L, respectively. She responded to the treatment with sodium nitrite and sodium thiosulfate. Although she had several relapses, each time she responded to sodium thiosulfate administration. On the fifth hospital day the cyanide level was 360 ug/L and thiocyanate level 30 mg/L and the patient was discharged on day six ...
Define sulforaphane. sulforaphane synonyms, sulforaphane pronunciation, sulforaphane translation, English dictionary definition of sulforaphane. n. A sulfureous phytochemical compound, C6H11NOS2, occurring in cruciferous vegetables and acting as an anticancer agent, antimicrobial, and antioxidant
Sulforaphane, a naturally organosulfur compound found in broccoli, showed to exert its neuroprotective effects through significantly attenuated the scopolamine-induced memory impairment and improved cholinergic system reactivity, as indicated by an increased ACh level, decreased AChE activity, and increased choline acetyltransferase (ChAT) expression in the hippocampus and frontal cortex(1). in a variety of acute and chronic neurodegenerative diseases, phytochemicals, isothiocyanate sulforaphane, derived from the hydrolysis of the glucosinolate glucoraphanin mainly present in Brassica vegetables, demonstrated its neuroprotective effects in several in vitro and in vivo studies, may be mainly ascribed to its peculiar ability to activate the Nrf2/ARE pathway(2). In dopaminergic neurotoxicity in mice induced by 6-hydroxydopamine (6-OHDA), the phytochemical showed the neuroprotective effect through its ability to enhance glutathione levels and its dependent enzymes (glutathione-S-transferase and ...

Many natural dietary foods and Chinese herbal medicines have been shown to exert obviously useful and therapeutic properties for human health [44]. The anticancer activity of isothiocyanates (ITCs) has been widely proofed [3, 44, 45]. In preclinical studies, the cancer-preventive efficacy of ITC treatments has been observed [6, 46, 47]. The anticancer mechanisms of ITC have been broadly investigated, including cell cycle arrest, anti-oxidation action, enhancement of DNA damage and repair, induction of apoptosis and autophagy, anti-metastasis, and elimination of cancer stem cells [6, 45, 46, 48]. Benzyl isothiocyanate (BITC) is one of the ITCs. BITC is a naturally-occurring constituent of cruciferous vegetable and found in Alliaria petiolata, pilu oil, cauliflower, cabbage, broccoli, and papaya seeds [1-3, 49, 50]. BITC has been found to induce apoptosis in various cancer cell lines, including breast cancer cells (MCF-7, HBL-100 and MDA-MB- 231) [51, 52], breast cancer stem cells (bCSC) [53], ...
Veratrine and sodium fluoride potentiate the twitch fiber reaction, as revealed by the changes in the first phase of the frogs rectus potassium contracture. Caffeine potentiates the reaction of both twitch and slow fibers. Sodium thiocyanate and chloroform mainly potentiate the reaction of slow fibers. Glucose, ethyl ether and acetophenone depress the twitch fiber reaction, potentiating, to various degrees, the slow phase. Only in a few cases is the reaction pattern of the muscle affected by changes in exposure time and concentration of these agents. The different actions of the sensitizers to potassium are discussed in the light of the present investigations.. ...

Epigenetics, an increasing focus of research around the world, refers not just to our genetic code, but also to the way that diet, toxins and other forces can change which genes get activated, or "expressed." This can play a powerful role in everything from cancer to heart disease and other health issues.. Sulforaphane was identified years ago as one of the most critical compounds that provide much of the health benefits in cruciferous vegetables, and scientists also knew that a mechanism involved was histone deacetylases, or HDACs. This family of enzymes can interfere with the normal function of genes that suppress tumors.. HDAC inhibitors, such as sulforaphane, can help restore proper balance and prevent the development of cancer. This is one of the most promising areas of much cancer research. But the new OSU studies have found a second epigenetic mechanism, DNA methylation, which plays a similar role.. "It appears that DNA methylation and HDAC inhibition, both of which can be influenced by ...
In a Food Scienec Topic in the Nuffield A Level Chemistry course in the UK quantitative Benedicts is used to determine the glucose content of drinks after standardisation against a glucose solution of known concentration. I can complete the calculation and know that quantitative Benedicts is used to introduce thiocyanate ions so that white CuSCN is precipitated instead of brick-red Cu2O (presumably to make the end-point easier to see. However methylene blue is suggested as an indicator and I cant discover its function or how it indicates and I have never been able to find or work out an equation for the reaction of glucose with Benedicts solution or even the actual formula of the comnplex Cu (II) ion in Benedicts solution. I, and my students, would be very grateful for this information. Many thanks ...

We were wondering if there is any way to perform genomic DNA preps from mammalian tissue culture cells without the use of phenol/chloroform extraction. There is an interesting article to this effect in Nucleic Acids Research, Vol. 18, No. 4, p. 1074. However, when we perform this method we are having problems with DNA degaradation. This article suggests the use of large glass particles and cells solubilized in guanidine thiocyanate/0.1 M EDTA (pH 8.0). Is there anyway to resolve this problem ...
