La nutrición en el periodo preconcepcional y los resultados del embarazo: revisión bibliográfica y propuesta de intervención del Dietista-Nutricionis…
2016
El estado nutricional de la madre antes y durante el embarazo se constata en los últimos años como uno de los factores ambientales más influyentes en el desarrollo fetal. Este estudio se centra en las primeras fases del proceso de gestación o periodo periconcepcional: preconcepción, concepción, implantación, placentación y embriogénesis; puesto que representan un paso crítico en los resultados del embarazo. Tras una revisión bibliográfica exhaustiva de 66 investigaciones publicadas entre los años 1990 y 2015, fueron el zinc, el hierro, el yodo, los ácidos grasos omega-3, el ácido fólico y otras vitaminas del grupo B, los minerales y micronutrientes para los que se han encontrado mayor evide…
Impiego di un modello predittivo per la microflora del salame S. Angelo in corso di asciugature
2008
The authors carried out a study in order to apply an interspecific competition model to predict the microflora behaviour of S.Angelo IGP salami during the ripening. They consider 3 bacterial population (Lactic Acid Bacteria, Enterobacteria and Listeria monocytogenes – LAB, Ent and Lmo) using the observed curves obtained in a previous work as validation. The model applied setting to 0 all interaction terms does not fit the observed curves while the introduction of 3 interaction terms (betaLmo/LAB = 0.65; betaEnt/LAB = 0.4; betaLmo/Ent = 0.18) produce a good agreement with the observed behaviour of all populations.
Deficit irrigation and maturation stage influence quality and flavonoid composition of ‘Valencia’ orange fruit
2016
BACKGROUND:Effects of continuous deficit irrigation (DI) and partial rootzone drying (PRD) treatments (50%ETc) in comparison with full irrigation (CI, 100% ETc) were investigated during ‘Valencia’ orange fruit maturation. Ultra-high-performance liquid chromatography/high-resolutionmass spectrometry was used to quantify hesperidin, narirutin, tangeritin, nobiletin, didymin and neoeriocitrin in the fruit juice and peel. RESULTS: No significant effect of irrigation was found on yield, juice soluble solids or acidity. Juice color was not influenced by irrigation or harvest date, whereas peel color increased during maturation and was more pronounced in CI and PRD fruits. Juice acidity reached a …
In Vitro Cytotoxic Effect of Aqueous Extracts from Leaves and Rhizomes of the Seagrass Posidonia oceanica (L.) Delile on HepG2 Liver Cancer Cells: Fo…
2023
Aqueous extracts from Posidonia oceanica’s green and brown (beached) leaves and rhizomes were prepared, submitted to phenolic compound and proteomic analysis, and examined for their potential cytotoxic effect on HepG2 liver cancer cells in culture. The chosen endpoints related to survival and death were cell viability and locomotory behavior, cell-cycle analysis, apoptosis and autophagy, mitochondrial membrane polarization, and cell redox state. Here, we show that 24 h exposure to both green-leaf- and rhizome-derived extracts decreased tumor cell number in a dose–response manner, with a mean half maximal inhibitory concentration (IC50) estimated at 83 and 11.5 μg of dry extract/mL, respecti…
Freeze dried pomegranate juices of Moroccan fruits: main representative phenolic compounds.
2022
The pomegranate (Punica granatum) is an ancient perennial plant species of the Punicaceae family. Its seeds are consumed as food or as juice. Previous studies have noted that pomegranate juice encompasses many active compounds with beneficial effects. The main goals of this work were to study the phenolic components of freeze-dried and reconstituted pomegranate juices obtained from 13 pomegranate genotypes growing in Morocco.We analyzed several pomegranate juices using high-performance liquid chromatography and high-resolution mass spectrometry to determine phenolic compounds. Twenty-seven bio-phenols, belonging to four different classes (phenolic acids, hydrolyzable tannins, anthocyanins, …
Biological and Proteomic Characterization of the Anti-Cancer Potency of Aqueous Extracts from Cell-Free Coelomic Fluid of Arbacia lixula Sea Urchin i…
2022
Echinoderms are an acknowledged source of bioactive compounds exerting various beneficial effects on human health. Here, we examined the potential in vitro anti-hepatocarcinoma effects of aqueous extracts of the cell-free coelomic fluid obtained from the sea urchin Arbacia lixula using the HepG2 cell line as a model system. This was accomplished by employing a combination of colorimetric, microscopic and flow cytometric assays to determine cell viability, cell cycle distribution, the possible onset of apoptosis, the accumulation rate of acidic vesicular organelles, mitochondrial polarization, cell redox state and cell locomotory ability. The obtained data show that exposed HepG2 cells under…
¿Se puede prevenir la obesidad infantil? Evaluación de una intervención educativa dirigida a fomentar hábitos saludables
2022
En los últimos años la sociedad ha sufrido grandes cambios, y, estos, afectan los hábitos saludables que practican las personas. Es por eso, que la obesidad infantil se ha convertido en un importante problema de salud pública. Por lo tanto, la escuela adquiere un papel fundamental: promover los hábitos saludables alimenticios en los niños y las niñas desde su comienzo en ella. Este trabajo gira en torno a una serie de actividades realizadas durante unas semanas del curso 2021 – 2022. En un grupo de alumnos/as de 5 a 6 años provenientes de un colegio situado en la población de Alberic (Valencia). Dada la necesidad observada de un grupo de alumnos/as que presentaba carencias en sus hábitos al…
