Antifungal effect of phenolic extract of fermented rice bran with Rhizopus oryzae and its potential use in loaf bread shelf life extension
2018
In this study the antifungal potential of a phenolic extract obtained from rice bran fermented with Rhizopus oryzae CECT 7560 and its application in the elaboration of bread was assessed.; Results: Eighteen compounds with antifungal potential were identified by LC-ESI-qTOF-MS in the extract: organic acids, gallates and gallotannins, flavonoids, ellagic acid and benzophenone derivatives. The extract was active against strains of Fusarium, Aspergillus and Penicillium, with minimum inhibitory concentration ranging from 390 to 3100 µg mL-1 and minimum fungicidal concentration variable from 780 to 6300 µg mL-1 . The strains that were most sensitive to the phenolic extract were F. graminearum, F.…
Trophic flexibility of the Atlantic blue crab Callinectes sapidus in invaded coastal systems of the Apulia region (SE Italy): A stable isotope analys…
2017
Abstract The Atlantic blue crab Callinectes sapidus is recognized as an Invasive Alien Species in the Mediterranean Sea. However, its trophic role and feeding flexibility in invaded benthic food webs have been addressed only recently. Here, field samplings were conducted in winter and summer in five coastal systems of the Apulia region (SE Italy), three located on the Ionian Sea (Mar Piccolo, Torre Colimena, and Spunderati) and two on the Adriatic Sea (Acquatina and Alimini Grande). Captured blue crabs were weighed and had their δ 13 C and δ 15 N isotopic signatures measured; their trophic level (TL) was estimated using the mussel Mytilus galloprovincialis as isotopic baseline. C. sapidus a…
The trophic position of the Atlantic blue crab Callinectes sapidus Rathbun 1896 in the food web of Parila Lagoon (South Eastern Adriatic, Croatia): A…
2016
The Atlantic blue crab Callinectes sapidus is to date widely distributed in the Mediterranean Sea, where is recognized as an Invasive Alien Species. Noticeably, while records of its occurrence are increasing, quantitative information on its functional role in the benthic food webs of invaded coastal habitats are scarce. Here, carbon and nitrogen isotopic signatures were measured in C. sapidus and other representative taxa of the benthic flora and fauna sampled in summer in the Parila Lagoon, a coastal basin located in the Neretva River estuary area (Croatia). d 15 N values of individual blue crab specimens were used to calculate their trophic position (TP) , using the filter feeder mussel M…
Dietary characterization of Savi s Warbler Locustaella luscinioides and Great Reed Warbler Acrocephalus rundinaceus in eastern Spain
2017
[EN] This research deals with two insectivorous reedbed-nesting songbirds, the Savi's Warbler Locustella luscinioides and the Great Reed Warbler Acrocephalus arundinaceus breeding at the Marjal de Pego-Oliva (Valencia-Alicante, Spain). Our aims were to study the diet and the prey selection of the two species and to assess the dietary differences between them. Diet composition has been assessed by examining samples off regurgitated food obtained using apomorphine as an emetic. Prey availability was estimated through standardized invertebrate sampling. The diet of the two warblers were significantly different and included arthropods belonging to the orders Araneida, Coleoptera, Hymenoptera, H…
Factors influencing infection patterns of trophically transmitted parasites among a fish community: host diet, host-parasite compatibility or both?
2011
20 pages; International audience; Parasite infection patterns were compared with the occurrence of their intermediate hosts in the diet of nine sympatric fish species in a New Zealand lake. Stomach contents and infection levels of three gastrointestinal helminth species were examined from the entire fish community. The results highlighted some links between fish host diet and the flow of trophically transmitted helminths. Stomach contents indicated that all but one fish species were exposed to these helminths through their diet. Host feeding behaviour best explained infection patterns of the trematode Coitocaecum parvum among the fish community. Infection levels of the nematode Hedruris spi…
Huanglongbing modifies quality components and flavonoid content of ‘Valencia’ oranges
2015
BACKGROUND: In order to evaluate the effect of citrus greening disease, or Huanglongbing (HLB), on quality components and flavonoid contents of ‘Valencia’ oranges, fruit from non-infected trees (control), from infected trees but symptom-less (asymptomatic) and from infected trees and showing clear HLB symptoms (symptomatic) were harvested in March and in May, 2013. Fruit peel, pulp and juice were separated, the main quality components were determined, and hesperidin, nobiletin, tangeretin, narirutin and didymin were quantified using liquid chromatography. RESULTS: Peel colour, total soluble solids and citric acid were similar in control and asymptomatic fruits. Symptomatic fruits were small…
Spanish population trends in Internet searches for information on different diets
2019
Abstract Objective To use Google Trends to explore the trends of interest of the Spanish population regarding information related to different types of diets, focused on those that are popular and with evidence-based studies, over the last 10 years. Material and methods The search trends referred to the terms “Mediterranean diet”, “ketogenic diet”, “low fat diet”, “intermittent fasting” and “vegan diet” were analyzed. The relative search volumes (RSV) of the terms were compared. The direction of the trend was studied using the Spearman's correlation coefficient (SC). Results “Mediterranean diet” was the most widely searched term, with a median RSV of 16 (interquartile range [IQR] 6; range 8…
Relation entre volume gastrique après sleeve et résultat pondéral : mythe ou réalité ?
2019
Introduction : La sleeve gastrectomie (SG) est devenue la technique de chirurgie bariatrique la plus réalisée en France. Cependant, les causes d’échec sont peu connues, et le volume gastrique (VG) pourrait y avoir un rôle. Le but de cette étude est donc d’analyser le lien entre le volume gastrique à un an et le succès pondéral. Patients et méthodes : Tous les patients obèses ayant bénéficié d’une SG entre septembre 2015 et juin 2017 ont bénéficié d’une volumétrie gastrique scanographique un an après la chirurgie. Le pourcentage d’excès de poids perdu à un an était mesuré pour évaluer le résultat pondéral et rechercher un lien avec le VG résiduel. Résultats : Cent soixante-huit patients cons…
Estudio de investigación cualitativa sobre las diferencias entre hombres y mujeres en la percepción de la obesidad, sus causas, abordaje y repercusio…
2018
Introducción: aunque la obesidad es un problema de salud multidimensional, pocos estudios de investigación cualitativa han analizado el discurso de personas obesas con perspectiva de género para conocer con mayor profundidad información difícilmente obtenible con técnicas cuantitativas.Objetivo: analizar el discurso de personas obesas mediante grupos de discusión en cuanto a factores que subyacen en la obesidad, percepción del riesgo de patologías, pérdida peso y otros factores relevantes.Métodos: se realizaron dos grupos de discusión en sesiones separadas, homogéneos por sexo, con un total de 14 participantes. Un moderador dirigió la sesión contemplando las distintas dimensiones del probl…
Bénéfices cardiovasculaires et rénaux des inhibiteurs de SGLT2 : mécanismes de la protection
2019
Resume Les inhibiteurs de SGLT2 ont montre, dans plusieurs etudes prospectives, leur benefice cardiovasculaire et renal avec, plus particulierement, une diminution rapide et tres significative des hospitalisations pour insuffisance cardiaque et des evenements renaux severes : doublement de la creatinine ou recours a l’epuration extra-renale. Le lien fort entre la physiopathologie de l’insuffisance cardiaque et renale explique l’analyse commune des hypotheses de protection de cette classe medicamenteuse. Les mecanismes precis rendant compte de l’amelioration de la fonction myocardique et renale sous inhibiteurs de SGLT2 ne sont pas encore eclaircis, mais plusieurs hypotheses peuvent etre ava…
