OBJECTIVES Determination of stages of colon cancer is done by biopsy usually after surgery. Metabolomics is the study of all the metabolites using LC-MS and 1HNMR spectroscopy with chemometric techniques. The stages of colon cancer were detected from patients' sera using 1HNMR. MATERIALS AND METHODS Five ml blood was collected from 16 confirmed patients referred for colonoscopy. One group of ...

The objectives of this study were to characterize a synthesis brom-isoflavanone (notated IF) with possible pharmacological activities, water insoluble and to examine the potential of beta-cyclodextrin to improve this property and obtain inclusion compounds that were analysed by different techniques: UV-Vis, IR, 1HNMR spectroscopy, thermal analysis. The presence of β-cyclodextrin rises the conte...

The photocatalytic degradation of dye Rhodamine B (RhB) in the presence of TiO2 nanostripe or P25 under visible light irradiation was investigated. The degradation intermediates were identified using Infrared spectra (IR spectra), 1H nuclear magnetic resonance (1HNMR) spectra, and gas chromatography-mass spectroscopy (GC-MS). The IR and the 1HNMR results showed that the large conjugated chromop...

Nowadays, the use of lasers and other biospectroscopic techniques such as Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy (ATR-FTIR), Mass, UV-Vis, FT-Raman, 1HNMR, 13CNMR and 31PNMR spectroscopies have had significant progress in treatment of cancer diseases [1-17]. Process of irradiation transmission and absorption in human cells’ tissues is very important in diagnosis an...

several 10-substituted anthralins were readily prepared. their oxidation with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone gave the corresponding novel heteroatomic systems. all derivatives were fully characterized by ir, mass and 1hnmr spectroscopy.

a novel complex of cadmium (ii) [cdl0.5(no3)(h2o)](1), l= n,n-bis (o-hydroxyacetophenone) ethylene diamine, have been synthesized as single crystal and nano size. compound 1 in nano size was obtained under sonochemical irradiation and has been characterized by ir, 1hnmr spectroscopy, x-ray powder diffraction (xrd) and scanning electron microscopy (sem). the gray single crystal of compound 1 has...
