Emulsion-based synthesis of PLGA-microspheres for the in vitro expansion of porcine chondrocytes.

2007

Abstract The in vitro cell expansion of autologous chondrocytes is of high interest in regenerative medicine since these cells can be used to treat joint cartilage defects. In order to preserve chondrocyte phenotype, while optimizing adhesion on microspheres, several processing parameters for the microsphere synthesis were varied. In this study three different polylactide-co-glycolides were used with differing lactide–glycolide ratios (85:15 and 50:50) and differing inherent viscosities. An emulsion route was established, where the polymer was dissolved in chloroform and then injected into a stirred polyvinyl alcohol–water solution at different polymer concentrations and different stirring …

Correlations between transmural mechanical and morphological properties in porcine thoracic descending aorta.

2015

Determination of correlations between transmural mechanical and morphological properties of aorta would provide a quantitative baseline for assessment of preventive and therapeutic strategies for aortic injuries and diseases. A multimodal and multidisciplinary approach was adopted to characterize the transmural morphological properties of descending porcine aorta. Histology and multi-photon microscopy were used for describing the media layer micro-architecture in the circumferential-radial plane, and Fourier Transform infrared imaging spectroscopy was utilized for determining structural protein, and total protein content. The distributions of these quantified properties across the media thi…

Elemental geochemistry of soils from the volcanic island of Pantelleria, Sicily: implications for Moscato wine production.

2006

The volcanic island of Pantelleria produces a naturally sweet wine Moscato di Pantelleria DOC obtained from the «Moscato d'Alessandria» (or «Zibibbo»), a grape favoured by hot climate. Geochemical and mineralogical investigations performed on soil profiles devoloped on rocks representative of the major outcropping lithologies (pantellerite, trachyte and alkalic basalt) show that the soils have preserved the parent material imprint. Consistently, values of the chemical index of alteration (CIA) indicate a low to moderate weathering degree for the rocks exposed in the Pantelleria area and consequently a low to moderate soil evolution. Soil-solution chemical analyses highlight that macro- and …

Pratiques et évolution de la vinification dans un cellier bourguignon à la fin du Moyen Âge : le cas de la collégiale Notre-Dame de Beaune (fin XIVe-…

2014

The accounts of the cellar of the collegiate church of Notre-Dame of Beaune are almost continuously preserved from the end of the 14th century to the French Revolution of 1789. Until the year 1507 the canons themselves exploited a part of their domain, located mainly in the territory of the city of Beaune. This enables us to describe precisely the current practices of this cellar, and thus the winemaking process of the " vin de Beaune " at the end of the Middle Ages. This article explores the different techniques in use, in both their materiality and in their specificities. We also try to point out the evolution of the practices from ca. 1380 to 1500, respecting the point of view of the med…

La construction des climats viticoles en Bourgogne, la relation du vin au lieu au Moyen Âge. Une culture du vin et du lieu en Bourgogne

2014

Climats is the technical term for portions of vineyards delimited and named according to specific wine qualities. They arose from the seventeenth century onwards as a specific terroir meaning in Burgundy. However, tradition still emphasizes the medieval actors of Burgundian viti-viniculture as dukes and monks as the determinants for the emergence of climats. Therefore it is worth exploring medieval history to decipher the relationship linking wine to place in the Middle Ages : for instance, the way wines were labelled in cellars and storerooms in Dijon. Some monastic communities were not accustomed to differentiating their wine according to the original place in which it grew. Human practic…

Le “plaisir sucré” de la duchesse : un point sur la production du « galant de Madame » à la fin du Moyen Âge. https://preo.u-bourgogne.fr/crescentis/…

2021

Among the range of products elaborated in the Dukes of Burgundy vineyards at the end of the Middle Ages, the galant is first quoted in 1383. This paper strives to shed new light upon the sources in which the galant appears, i.e. the accountability documentation of the Dukes’ vineyards. Our research focuses on two demesnes located near Dijon: Talant and Chenôve.The study of this rare product (2-4% of total production), which was certainly flavored with gentian, shows that the notion of fortified wine should be reconsidered for the 14th and 15th centuries. The galant was obtained only by heating white grape must in a cauldron, searching to reach a diminution of one- or two-thirds of the basic…

Multivariate regression analysis applied to the calibration of equipment used in pig meat classification in Romania.

2016

This paper highlights the statistical methodology used in a dissection experiment carried out in Romania to calibrate and standardize two classification devices, OptiGrade PRO (OGP) and Fat-o-Meat'er (FOM). One hundred forty-five carcasses were measured using the two probes and dissected according to the European reference method. To derive prediction formulas for each device, multiple linear regression analysis was performed on the relationship between the reference lean meat percentage and the back fat and muscle thicknesses, using the ordinary least squares technique. The root mean squared error of prediction calculated using the leave-one-out cross validation met European Commission (EC…

Lactobacillus uvarum sp. nov. - A new lactic acid bacterium isolated from Spanish Bobal grape must

2008

Five strains isolated from grape musts in Spain in 1997, have been characterized by several molecular techniques, and three of them have been identified as pertaining to a new species. All strains are Gram-positive rods, aerotolerant and homofermentative bacteria that do not exhibit catalase activity. Phylogenetic analysis based on 16S rRNA gene sequences placed these strains within the genus Lactobacillus, closely related to Lactobacillus mali. DNA-DNA hybridization experiments confirmed that strain 71 belongs to the lately described species L. satsumensis, strain 88 belongs to L. mali and the other three isolates have an independent status at species level. Restriction analysis of the amp…
