Development of a quantitative multi-compound method for the detection of 14 nitrogen-rich adulterants by LC-MS/MS in food materials.

Nancy Frank et al.

Food additives & contaminants. Part A, Chemistry, analysis, control, exposure & risk assessment, 34(11), 1842-1852 (2017-09-05)

The increasing number of food frauds using exogenous nitrogen-rich adulterants to artificially raise the protein content for economically motivated adulteration has demonstrated the need for a robust analytical methodology. This method should be applicable for quality control in operations covering

Detection of 3-amino-1,2,4-triazine adulteration in milk using an oxidation product 3-amino-1,2,4-triazin-5(2H)-one.

Grant Abernethy et al.

Journal of chromatography. A, 1285, 165-167 (2013-03-12)

A rapid liquid chromatography-mass spectrometry method to detect 3-amino-1,2,4-triazine (ATZ) in milk was developed as part of a programme to set up methods for detecting the economically motivated adulteration of raw milk with nitrogen-containing compounds. When ATZ was added to

Mechanism of the sulfurisation of phosphines and phosphites using 3-amino-1,2,4-dithiazole-5-thione (xanthane hydride).

Jirí Hanusek et al.

Organic & biomolecular chemistry, 5(3), 478-484 (2007-01-26)

Contrary to a previous report, the sulfurisation of phosphorus(III) derivatives by 3-amino-1,2,4-dithiazole-5-thione (xanthane hydride) does not yield carbon disulfide and cyanamide as the additional reaction products. The reaction of xanthane hydride with triphenyl phosphine or trimethyl phosphite yields triphenyl phosphine

Analysis of regional hemodynamic regulation in response to scald injury.

P A Taheri et al.

The Journal of clinical investigation, 93(1), 147-154 (1994-01-01)

Ultrasonic probes were placed around dog femoral arteries to record blood flow. Hind paw scalding with boiling water (5 s) caused a marked increase in ipsilateral femoral blood flow that persisted for the 2-h observation period. Contralateral femoral blood flow

Nitro containing L-arginine analogs interfere with assays for nitrate and nitrite.

S S Greenberg et al.

Life sciences, 57(21), 1949-1961 (1995-01-01)

We evaluated the effect of in vivo and in vitro administration of nitro-containing and nitro-deficient L-arginine-derived nitric oxide (NO) synthase inhibitors on the measurement of NO in plasma, urine and HEPES buffered physiologic salt solution (PSS) by ozone chemiluminescence and

A novel source of methylglyoxal and glyoxal in retina: implications for age-related macular degeneration.

Kee Dong Yoon et al.

PloS one, 7(7), e41309-e41309 (2012-07-26)

Aging of retinal pigment epithelial (RPE) cells of the eye is marked by accumulations of bisretinoid fluorophores; two of the compounds within this lipofuscin mixture are A2E and all-trans-retinal dimer. These pigments are implicated in pathological mechanisms involved in some

Rapid induction of messenger RNA for nitric oxide synthase II in rat neutrophils in vivo by endotoxin and its suppression by prednisolone.

J Kolls et al.

Proceedings of the Society for Experimental Biology and Medicine. Society for Experimental Biology and Medicine (New York, N.Y.), 205(3), 220-229 (1994-03-01)

Nitric oxide is believed to participate in nonspecific cellular immunity. Gram negative bacterial endotoxins increase the production of reactive nitrogen intermediates (RNI) in phagocytic cells by inducing the enzyme nitric oxide synthase II (NOS II). Anti-inflammatory glucocorticoids attenuate endotoxin-induced increases

Crystal structure of 3-amino-1,2,4-triazin-5(2H)-one.

Long-Chih Hwang et al.
