Recently, Shen et al. (Analyst, 2010, 135, 302) reported on a flow injection analysis (FIA) ESI-MS/MS approach for the determination of the short-lived gaseous nitric oxide (NO) in biological samples. This method is based on the reaction of NO, and p

Asymmetric dimethylarginine (ADMA; N(G),N(G)-dimethyl-L-arginine) is the most important endogenous inhibitor of nitric oxide synthase and a potential risk factor for cardiovascular diseases. This article describes a gas chromatographic-tandem mass sp

In a former presentation, we reported the failure of commanding officers after a 320-km-long chain march. In this study, 64 commanding officers of a tank battalion were questioned regarding subjective health disturbances similar to the disturbances w

Highly contradictory data exist on the normal plasma basal levels in humans of S-nitrosoproteins, in particular of S-nitrosoalbumin (SNALB), the most abundant nitric oxide (.NO) transport form in the human circulation with a range of three orders of

A gas chromatographic-mass spectrometric method for the determination of nitric oxide synthase activity is described. The method is based on the gas chromatographic-mass spectrometric measurement of L-[15N2]arginine-derived [15N]nitrite as its pentaf

A gas chromatographic-mass spectrometric (GC-MS) method is described for the quantitative determination of the S-nitroso compounds S-nitroso-cysteine (SNC) and S-nitroso-glutathione (GSNO) using their (15)N-labeled analogs, i.e., S(15)NC and GS(15)NO

A gas chromatographic–mass spectrometric method for the quantitative determination of S-nitrosoalbumin (SNALB) in human plasma is described. The method is based on selective extraction of SNALB and its 15N-labeled SNALB analog (S15NALB) used as int

3-Nitro-L-tyrosine is produced in vitro and in vivo by the nitration of tyrosine and tyrosine residues in proteins. Plasma 3-nitro-L-tyrosine has been suggested as an index of oxidative damage in living organisms that depend on nitrating species. For
