Olive Fruit Phenols Transfer, Transformation, and Partition Trail during Laboratory-Scale Olive Oil Processing.

This work is the most comprehensive study on the quantitative behavior of olive fruit phenols during olive oil processing, providing insight into their transfer, transformation, and partition trail. In total, 69 phenols were quantified in 6 olive matrices from a three-phase extraction line employing ultra high pressure liquid chromatography-diode array detection analysis. Crushing had a larger effect than malaxation in terms of phenolic degradation and transformation, resulting in several new evolutions of respective derivatives.

Phenolic Profiling of Olives and Olive Oil Process-Derived Matrices Using UPLC-DAD-ESI-QTOF-HRMS Analysis.

All of the matrices entailed in olive oil processing were screened for the presence of known and new phenol constituents in a single study, combining an ultra high pressure liquid chromatography system with diode array and electrospray ionization quadrupole time-of-flight high resolution mass spectrometry (ESI-QTOF-HRMS) detection. Their trail was followed from the fruit (peel/pulp and stone) to the paste and final products, i.e.

Differences in the structure of anthocyanins from the two amphibious plants, Lobelia cardinalis and Nesaea crassicaulis.

The foliar anthocyanin profiles of two amphibious plants, Nesaea crassicaulis and Lobelia cardinalis were analysed for the first time. N. crassicaulis produced very simple anthocyanins, achieving the highest concentrations when grown submerged.

Calorimetric and dielectric studies of ferroelectric sodium nitrite confined in a nanoscale porous glass matrix.

Heat-capacity measurements of the sodium nitrite confined in a nanoscale porous glass matrix show that the intermediate incommensurate phase, present in the bulk, has disappeared and that the first-order ferroelectric transition becomes suppressed and gradual. The ferroelectric transition temperature is shifted considerably to lower temperatures. Two noncritical dielectric modes were observed; however, the observed giant growth of the dielectric constant on heating through the transition temperature TC is shown to be mainly due to the electrode polarization effect.

Expression of CD34, alpha-smooth muscle actin, and transforming growth factor beta1 in squamous intraepithelial lesions and squamous cell carcinoma of the larynx and hypopharynx.

Aim Of The Study: There is increasing evidence that stromal reaction in cancer has an important diagnostic and prognostic significance. Recent studies have shown that CD34-positive stromal cells and myofibroblasts may play an important role in host response to invasive cancer. The aim of our study was to analyze the expression of CD34, alpha-smooth muscle actin (SMA), and transforming growth factor beta1 (TGFbeta1) in squamous intraepithelial lesions (SILs) and squamous cell carcinoma (SCC) of the larynx and hypopharynx, to establish their significance, and to elucidate the mechanism of myofibroblast formation.
