Sicilian pistachio (Pistacia vera L.) nut inhibits expression and release of inflammatory mediators and reverts the increase of paracellular permeabi…

Background Dietary approaches to control inflammatory bowel diseases (IBD) may include proanthocyanidin-rich foods. Our previous research showed that a hydrophilic extract from Sicilian pistachio nut (HPE) contains sub- stantial amounts of proanthocyanidins and possesses anti- inflammatory activities. Purpose We studied the effects of HPE and of its poly- meric proanthocyanidin fraction (PPF) in a cell model that simulated some conditions of IBD, consisting of interleukin (IL)-1b-stimulated Caco-2 cells. Methods HPE was prepared by Pistacia vera L. nuts, and PPF was isolated from HPE by adsorbance chromatogra- phy. Proanthocyanidins were quantified as anthocyanidins after acidic hydrolysis.…
Optimization of the Red Tilapia (Oreochromis spp.) Viscera Hydrolysis for Obtaining Iron-Binding Peptides and Evaluation of In Vitro Iron Bioavailabi…
2020
Iron deficiencies continue to cause significant health problems in vulnerable populations. A good strategy to combat mineral deficiency includes fortification with iron-binding peptides. This research aims to determine the optimal conditions to hydrolyze red tilapia viscera (RTV) using Alcalase 2.4 L and recovery of iron-binding protein hydrolysate. The result showed that under the optimal hydrolysis condition including pH 10, 60 °
Mecanismos de transporte y toxicidad intestinal de especies de mercurio presentes en los alimentos
2014
El mercurio es un metal tóxico ampliamente distribuido en el medioambiente. Las formas químicas mayoritarias en los alimentos son el mercurio mercúrico [Hg(II)] y el metilmercurio (CH3Hg). La principal vía de exposición para el ser humano la constituye la dieta, siendo los productos pesqueros los que mayor aporte de mercurio realizan. Teniendo en cuenta que la principal vía de exposición al mercurio es la oral, el tracto gastrointestinal se considera la puerta de entrada de este tóxico al organismo. Estudios in vivo han demostrado que el Hg(II) presenta una moderada absorción (2-38%) mientras que el CH3Hg es absorbido prácticamente en su totalidad. Aunque se conocen los ratios de absorción …
