Analysis of deuterium labeled blood lipids by chemical ionization mass spectrometry
Lipids, 1985AbstractA quantitative analytical method has been developed to analyze methyl esters of blood fatty acids derived from human subjects fed deuterium‐labeled fats. The GCMS computer method provides for the analysis of the fed deuterium‐labeled fatty acids, the naturally occurring blood fatty acids and new fatty acids formed by chain elongation or ...

7Li MR measures of blood lithium—correlation with chemical analysis data
Magnetic Resonance Imaging, 2004Lithium is used in the treatment and prophylaxis of manic-depressive illness. A narrow therapeutic range of lithium (0.4-1.2 meq/l) requires constant monitoring of these levels to avoid neurotoxicity and overdose. It is general practice to measure plasma lithium levels as a guide to monitor the therapy. Efforts to predict the concentration of Li at its

A multi-dimensional analysis of three chemical quantities in the blood
Medical Informatics, 1991A three-dimensional model for the analysis of the three quantities pH, pCO2 and base excess (BE), as measured in arterial blood, is presented. Whereas the conventional analysis of these quantities relies on reference regions as established from the univariate distributions, treating the quantities as uncorrelated, the present model estimates the ...

Pulse Spectrum Analysis of Chemical Factory Workers with Abnormal Blood Test
The American Journal of Chinese Medicine, 1996Double blind tests to check the correlation between pulse diagnosis and liver function tests were performed. Blood tests including T-Bil, D-Bil, SGOT and SGPT of 70 chemical factory workers were compared with pulse analysis. Special attention was paid to the indicators of liver and lung meridians for pulse diagnosis.

Journal of Analytical Toxicology, 1982
A chemical method for the quantitative analysis of organochlorine pesticide residues present in human blood was scaled-up to provide increased sensitivity and extended to include organochlorine industrial chemicals. Whole blood samples were extracted with hexane, concentrated, and analyzed without further cleanup by gas chromatography with electron ...

Chemical Isotope Labeling LC-MS for Human Blood Metabolome Analysis
2018Blood is a widely used biofluid in discovery metabolomic research to search for clinical metabolite biomarkers of diseases. Analyzing the entire human blood metabolome is a major analytical challenge, as blood, after being processed into serum or plasma, contains thousands of metabolites with diverse chemical and physical properties as well as a wide ...

Rapid and quantitative blood amino acid analysis by chemical ionization mass spectrometry
Biological Mass Spectrometry, 1977A quantitative analysis of amino acids in microsamples of dried blood spots by chemical ionization mass spectrometry has been developed. Isotope ratio determination was used as the quantitating technique via multiple labelled internal standards. This procedure yields excellent precision and accuracy as demonstrated by the analysis of known amino acid ...

Microstructure and chemical analysis of blood-contaminated mineral trioxide aggregate.
International endodontic journal, 2012To test the hypothesis that blood contamination has a detrimental effect on the chemical properties of Mineral trioxide aggregate (MTA).The effects of whole, fresh human blood on the microstructure and elemental chemistry of MTA were evaluated using scanning electron microscopy and energy-dispersive X-ray analysis, respectively.
