The title complex, [Mn(NCS)(2)(C(13)H(19)NO(4))] {systematic name: [3,6,9,12-tetra-oxa-18-aza-bicyclo-[12.3.1]octa-cosa-14(18),15,17-triene-κ(5)N,O,O',O'',O''']bis-(thio-cyanato-κN)manganese(I-I)}, was obtained by the reaction of MnCl(2)·4H(2)O and NaSCN with pyridino-15-crown-5. The Mn(2+) center has a distorted penta-gonal bipyramidal coordination geometry, coordinated by four O atoms and one...

Oratile Semong and Bareki Shima Batlokwa The monitoring of thiocyanate (SCN−) in food is consumer health safety relevance. In this work, a colorimetric method for the detection SCN− milk using silver nanoparticles (AgNPs) nanozyme presented.

Thiocyanate (SCN?) present in irrigation water can have negative effects on plant growth and crop yields. Addition of regulators (PGRs) alleviate toxic stress to plants. In the current study, we established a grey situation decision-making model (GSDM) integrate data RT-qPCR analysis for screening optimal addition PGRs minimise pollution stress. The (i.e., jasmonic acid [JA], indole-3-acetic [I...

Letter by Spence Regarding Article, “Differential Effect of B-Vitamin Therapy by Antiplatelet Use on Risk of Recurrent Vascular Events After Stroke” To the Editor: It is likely that there was a problem with reverse causality in the article by Arshi et al, which found that B vitamins were harmful among patients taking antiplatelet agents in the Vitamin Intervention in Stroke Prevention Trial (VI...

OBJECTIVES Smoking is associated with false-positive rheumatoid factor (RF). We explored the dose-response relationship of this association, using smoking history and serum cotinine and thiocyanate concentrations as measures of tobacco exposure. METHODS A total of 6947 men and women aged 30 yr or over and free of clinical arthritis were included in the Mini-Finland Health Survey carried out b...

HAVE INSTITUTED a colorimetric chloride procedure which has been in use for 3 years in our laboratory and has met with great success. This colorimetric method is based on a procedure used in automated syStems* (2, 3). It is extremely simple, quite accurate, and gives highly reproducible results even in the hands of student technicians. Those laboratories not having access to a chloridometer or ...

The presence of specific chemical additives in the redox electrolyte results in an efficient increase of the photovoltaic performance of dye-sensitized solar cells (DSCs). The most effective additives are 4-tert-butylpyridine (TBP), N-methylbenzimidazole (NMBI) and guanidinium thiocyanate (GuNCS) that are adsorbed onto the photoelectrode/electrolyte interface, thus shifting the semiconductor's ...

Traditional RNA extraction methods rely on the use of hazardous chemicals such as phenol, chloroform, guanidinium thiocyanate to disrupt cells and inactivate RNAse simultaneously. RNA isolation from Caenorhabditis elegans presents another challenge due to its tough cuticle, therefore several repeated freeze-thaw cycles may be needed to disrupt the cuticle before the cell contents are released. ...

The synthesis of two new thiocyanate free Ru(II) complexes with different pyrid-2-yl tetrazolate ligands is reported, along with their electrochemical, spectroscopic and theoretical characterization. The corresponding dye-sensitized solar cell devices were prepared, leading to 3.4% conversion efficiency, promising data, considering the simplicity of the ligands and the high chemical stability o...
