The endogenous metabolites in serum from all of rats were analyzed by 1H-NMR coupled with multivariate statistical analysis. Results Compared with the control group, the levels of lipids, lactic acid, and acetone in serum of rats in the model group increased while the levels of alanine, valine...

Similarly, four biomarkers (glutamine, acetone, acetate, and choline) were able to precisely (ROC; 0.96) discriminate, 92.4% of OLK cases from OSCC with considerable sensitivity and specificity. 1H NMR-based metabolic fingerprint obtained for oral cancer is remarkable, even for OLK stage. ...
(step C). New solvent is changed, and the cleaning isfinished with clean acetone (step D). This acetone can be used for the next time of cleaning. The number of NMR tubes that can be cleaned at once depends only on the size of the be...
(0.004 mmol) in 2 mL of solvent was injected into a SFMT reactor (volume = 1.5 mL). The reaction was conducted at 50°C under 18 W blue LED irradiation for 48 h, unless otherwise stated. a 0.2 M HX solution in CH3CN was used. b Yields based on analysis of the crude 1H NMR ...

NMR spectra were recorded on a Bruker Avance III 400 MHz or an Agilent DD2 500 MHz NMR spectrometer. IR spectra were recorded on a Thermo Scientific Nicolet 380 FT-IR spectrometer. Melting points are uncorrected and were recorded on an SGW X-4 apparatus. High-resolution mass spectra (...
It is slightly soluble in water and highly soluble in ethanol and acetone. The molecular structure of ibuprofen consists of a propionic acid derivative with a benzene ring, containing carbon-carbon single bonds, a carboxyl group, and a methyl group. Ibuprofen is a synthetic compound, first ...
1H NMR spectroscopyRheumatoid arthritisRheumatoid arthritis is a chronic autoimmune-based inflammatory disease that leads to progressive joint degeneration, disability, and an increased risk of cardiovascular complications, which is the main cause of mortality in this population of patients. Although several...
