Factors associated with milk urea concentrations in Girgentana goats
2010
A total of 1,481 milk samples of 166 Girgentana goats, taken along the entire lactation, were utilised to evaluate the effect of non nutritional factors on milk urea (MU). Parity, stage of lactation and month of sampling significantly influenced MU, while no effect was found for born kids number. The first kidding goats produced lower MU than multiparous goats. Trend of MU was similar to milk production course with a peak found at 60 DIM. The different MU levels between several months of production are often linked to pasture chemical variations.
Efectos de la gestión de la Calidad en el desarrollo de la exploración organizativa. Análisis de la industria agroalimentaria ecológica española
2021
La exploración organizativa se ha posicionado como un tema de gran interés, poco estudiado y de gran relevancia en la literatura actual, debido a su importancia como herramienta fundamental para asegurar la sostenibilidad, rentabilidad y supervivencia de las organizaciones (Greco, Charlier & Brown, 2019; Josephson, Johnson & Mariadoss, 2016; Levinthal & March, 1993). En cuanto a su relación con la gestión de la calidad y la formalización, en la literatura especializada no hay acuerdo sobre cuál es el papel que estas desempeñan en su desarrollo, con diferentes posturas a favor y en contra de estas relaciones. Basándonos en una extensa y profunda revisión de la literatura, nosotros analizamos…
Rapid Assessment of Gray Mold (Botrytis cinerea) Infection in Grapes with a Biosensor System
2015
Abstract: Botrytis cinerea is the causative agent of gray mold disease, which causes considerable economic losses to winemakers. The extent of gray mold infection of winegrapes is commonly visually estimated, a method that is prone to assessor bias. Here, we used rapid and simple enzyme-based screening consisting of carbon-electrode, screen-printed amperometric biosensors to estimate gluconic acid and glycerol concentration in winegrapes infected with different degrees of B. cinerea. The lower limits of quantification of the screen-printed amperometric biosensors were 3 mg/L for gluconic acid (corresponding to an infection rate of less than 1%) and 35 mg/L for glycerol; the response times w…
A luminal glycoprotein drives dose-dependent diameter expansion of the Drosophila melanogaster hindgut tube
2012
An important step in epithelial organ development is size maturation of the organ lumen to attain correct dimensions. Here we show that the regulated expression of Tenectin (Tnc) is critical to shape the Drosophila melanogaster hindgut tube. Tnc is a secreted protein that fills the embryonic hindgut lumen during tube diameter expansion. Inside the lumen, Tnc contributes to detectable O-Glycans and forms a dense striated matrix. Loss of tnc causes a narrow hindgut tube, while Tnc over-expression drives tube dilation in a dose-dependent manner. Cellular analyses show that luminal accumulation of Tnc causes an increase in inner and outer tube diameter, and cell flattening within the tube wall,…

Does oral health affect food comfortability and bolus properties during consumption of dairy products in elderly population?
2017
The elderly population is growing increasingly. In 2030, 1/3 of the population will be over 60 years old. However this population has specific nutritional needs and often, oral impairments such as loss of tooth and/or decrease of salivary flow. Therefore it is necessary to develop foods adapted for the elderly, in terms of organoleptic properties and nutritional composition. In this context, the purpose of this work is to study the impact of oral impairments of elderly persons on food comfortability and bolus properties during the consumption of dairy products.76 elderly persons (ages 66 to 88, 42 women and 34 men), with or without oral health problems in terms of dental and/or salivary sta…

La biopréservation: une stratégie d’avenir pour la conservation des aliments
2015
N° d'article 201511121820; La demande grandissante des consommateurs pour des produits alimentaires à teneur réduite en conservateurs pousse les industriels de l’agroalimentaire à rechercher des méthodes de conservation alternatives. Dans ce contexte, la bioprotection s’impose comme un procédé à fort potentiel. Cette technique consiste à inoculer sur les aliments des cultures de bactéries protectrices. Celles-ci, par l’intermédiaire de plusieurs mécanismes, vont inhiber la croissance de bactéries pathogènes et d’altération telles que Listeria monocytogenes et Salmonella. Cependant, cette technique n’a pas d’effet sur les spores bactériennes. Ainsi, l’objet central du projet de recherche ANR…
Funcionalidad de hidrocoloides en la digestibilidad de emulsiones aceite/agua
2019
La presente tesis doctoral se centra en el estudio de las propiedades físicas y la digestibilidad lipídica de emulsiones alimentarias basadas en hidrocoloides, para valorar su aplicación como sustitutos de grasa en la reformulación de un producto final más saludable. La obtención de alimentos más saludables se puede conseguir a través de diferentes vías; o bien disminuyendo la cantidad de grasa presente, o bien disminuyendo la digestibilidad de la grasa, considerándose también un aspecto clave la mejora del perfil lipídico. Teniendo estos aspectos en cuenta, se diseñaron y estudiaron emulsiones formuladas con diferentes tipos de grasa estabilizadas por diferentes tipos de matrices poliméric…
