The stability over time (repeatability) for the determination of site-specific 13C/12C ratios at natural abundance by quantitative 13C NMR spectroscopy has been tested on three probes: enriched bilabeled [1,2-13C2]ethanol; ethanol abundance; and vanillin abundance. It is shown in all cases that standard deviation a series measurements taken every 2-3 months periods between 9 13 equal to or smaller than calculated from 5-10 replicate made single sample. precision which can be achieved using...
This study was conducted to assess the antioxidant potential of polyphenolic extracts from Rhizophora mucronata and Avicennia marina as natural preservatives in comparison with synthetic butylated hydroxytoluene (BHT) rosemary extract. Antioxidant activities were assessed by 2,2-diphenyl-1-picrylhydrazyl (DPPH), oxygen radical absorbance capacity (ORAC), total phenolic content (TPC). Extracts blended into linseed oil evaluated for oxidative stability using a 15-day Schaal oven test....
Periodontitis is characterized by the loss of supporting tissues teeth in an inflammatory-infectious context. The diagnosis relies on clinical and X-ray examination. Unfortunately, signs tissue destruction occur late disease progression. Therefore, it mandatory to identify reliable biomarkers facilitate a better earlier management this disease. To end, saliva represents promising fluid for identification as metabolomic fingerprints. present study used high-resolution 1H-nuclear magnetic...
The recent development of 13C NMR to measure absolute 13C/12C ratios at natural abundance has made it possible examine site-by-site variation abundance. This technique been applied two common physical processes: distillation and column chromatography. It is shown that the target molecules, ethanol vanillin, respectively, both show isotopic fractionation differs in size and/or sense each carbon atom. observation this disparity behavior novel unexpected. SNIF-NMR appears as a new effective...
Fluorescence landscapes with excitation wavelengths varying between 280 and 400 nm, emission in the range of 300–650 nm were scanned directly on oil samples throughout storage capped uncapped flasks for 15 days at 60 °C. PARAFAC analysis fluorescence showed presence three fluorophores edible oils, which are strongly dependent conditions. The spectra resolved into profiles pure fluorescent compounds, ascribed to be oxidation products vitamin E. complexity data sets was suitable modelling....
In the present study, sponge cakes, produced at pilot scale, were monitored during aging (i.e., 1, 3, 6, 9, 16, and 20 days) by three different analytical techniques. For texture analyzer, hardness elasticity of crumb cakes found to significantly increase decrease, respectively, throughout aging. Color parameters (L*, a*, b*) showed only slight change aging, a high correlation (R(2) = 0.88) was observed between whiteness yellowness. Tryptophan fluorescence spectra (excitation, 290 nm;...
Targeted PEGylated liposomes could increase the amount of drugs or radionuclides delivered to tumor cells. They show favorable stability and pharmacokinetics, but steric hindrance PEG chains can block binding targeting moiety. Here, specific interactions between an antihapten antibody (clone 734, for DTPA-indium complex) DTPA-indium-tagged were characterized by surface plasmon resonance (SPR). Non-PEGylated fused on CM5 chips whereas did not. By contrast, both non-PEGylated attached L1...
Abstract Indium-DTPA-tagged liposomes were studied in the present work as carriers of vivo 212 Pb/ Bi generator to be used targeted alpha therapy. The liposomal uptake Pb, into preformed liposomes, was investigated using different lipophilic chelate (DCP, 2,3-dimercapto-1-propanol (BAL), sodium acetate, and A23187), a function various parameters (temperature, concentrations lipids, DTPA, ...) with Pb tracer. Different formulations tested evaluate radiolabeling efficiency. No complexing agent...
Abstract In this work, front‐face fluorescence spectroscopy coupled with chemometric tools are used for the monitoring of rapeseed, sunflower, extra virgin olive, and linseed oil. The oil samples heated at 60 °C up to 15 days. excitation spectra scanned in range 270–420 nm 250–310 after emission wavelength set 450 330 nm, respectively. primary secondary lipid oxidation products also determined on same samples. By applying partial least square discriminant analysis (PLS‐DA) each spectral...
The impact of varying fat and gelatinization on the starch protein secondary structures was investigated in slurry batter systems using mid-infrared (MIR) spectroscopy. Following addition both thickening agent oil, absorbance ratio R1: 1022 cm−1/995 cm−1 ranged from 0.99 to 1.1 0.85 0.89 for slurries batters, respectively. level β-turn structure decreased (from 20.2 17.9%) batters 18.8 16.4%) with addition. Similarly, oil incorporation reduced amount 9.1%) 16.4%). This result confirms...
