Metabolomics, a modern branch of chemical biology, provides qualitative and quantitative information about the metabolic states of organisms or cells at the molecular level. Here we report non-targeted, metabolomic analyses of human blood, using liquid chromatography-mass spectrometry (LC-MS). We compared the blood metabolome to the previously reported metabolome of the fission yeast, Schizosac...
The absolute quantification of blood plasma metabolites by proton NMR spectroscopy is complicated by the presence of a baseline and broad resonances originating from serum macromolecules and lipoproteins. A method for spectral simplification of proton NMR spectra of blood plasma is presented. Serum macromolecules and metabolites are completely separated by utilizing the large difference in tran...
In the present study, 30 multiparous close-up Holstein cows (average parity 3.8) were allocated in a completely randomized design with four treatments to evaluate the effect of chromium, monensin and their combination on blood metabolites and liver enzymes. Experimental treatments were: 1) control (no supplementation) 2) monensin (400 mg/d/h) 3) Chromium (0.03 mg/BW0.75) 4) combination of both ...
We report a fluorometric method for detecting diazepam, chlordiazepoxide, oxazepam, chlorazepate, and (or) their major metabolites in blood, urine, or gastric contents at low therapeutic concentrations. The drugs are first hydrolyzed to their respective benzophenones and converted to highly fluorescent 9-acridanones. Total benzodiazepines (parent plus metabolites) in blood and gastric contents ...
A current challenge in metabolomics is the reliable quantitation of many metabolites. Limited resolution and sensitivity combined with the challenges associated with unknown metabolite identification have restricted both the number and the quantitative accuracy of blood metabolites. Focused on alleviating this bottleneck in NMR-based metabolomics, investigations of pooled human serum combining ...
This article contains NMR (nuclear magnetic resonance) experimental data, obtained by the NMR Varian 400 MHz spectrometer (USA) which can be used for the metabolites identification in human blood. Data include analyzed NMR spectra of plasma proteins extracted from human blood of 24 patients (0-5 years old) with the confirmed acute leukemia diagnosis. Data can provide information about metabolit...
Serum and liver metabolites in rats fed red ginseng (RG) were analyzed by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry. The mass data were analyzed by partial least squares-discriminant analysis (PLS-DA) to discriminate between control and RG groups and identify metabolites contributing to this discrimination. The RG group was clearly separated from the co...
nitric oxide (no) is a simple ubiquitous signaling molecule and plays important roles in almost every biological system. recent evidences suggest that no may act as an endocrine molecule. the aim of this review is considering available literature on endocrine roles of no and/or its metabolites, i.e. nitrite and nitrate. existing data suggest the idea that no is a hormone that after production i...
BACKGROUND In Bangladesh, tens of millions of people have been consuming waterborne arsenic for decades. The extent to which As is transported to the fetus during pregnancy has not been well characterized. OBJECTIVES We therefore conducted a study of 101 pregnant women who gave birth in Matlab, Bangladesh. METHODS Maternal and cord blood pairs were collected and concentrations of total As w...
