Les effets de la livraison à domicile sur l'accès aux produits alimentaires: le cas des grandes surfaces alimentaires et des cybermarchés de l'aire u…
2012
International audience; L’accessibilité des populations aux Grandes Surfaces Alimentaires (1) (GSA) est différenciée selon les espaces. Alors qu’au cœur des villes, les urbains peuvent accéder à pied à une offre diversifiée, les périurbains et les ruraux doivent parcourir plusieurs kilomètres en voiture pour accéder au supermarché le plus proche (Motte-Baumvol, 2008). Si une très grande majorité de périurbains n’éprouvent pas de difficultés, certains y font face plus difficilement tels que les ménages sans voiture, les personnes âgées ou les familles avec des enfants en bas âge. Pour ces ménages, la livraison à domicile, notamment à partir de la vente en ligne, peut constituer un moyen d’am…
Dimensions fractales et réalités périurbaines. L'exemple du Sud de Bruxelles
2004
This exploratory paper aims at showing how the fractal dimension can be used to characterise the spatial structure of built-up areas within the periurban fringe. The southern periphery of Brussels is considered here. Two estimation techniques (correlation and dilation) are applied to surface areas, and one (correlation after dilation) to the borders of built-up areas. They are applied to windows of fixed size. Fractal dimensions are then compared with traditional socio-economic and morphological indicators. The results are interpreted in the context of urban sprawl and polycentric development of the peripheries. These analyses confirm the usefulness of the fractal approach for describing bu…

Nanodesign of new self-assembling core-shell gellan-transfersomes loading baicalin and in vivo evaluation of repair response in skin
2017
Gellan nanohydrogel and phospholipid vesicles were combined to incorporate baicalin in new self-assembling core-shell gellan-transfersomes obtained by an easy, scalable method. The vesicles were small in size (~107 nm) and monodispersed (P.I. ≤ 0.24), forming a viscous system (~24 mPa/s) as compared to transfersomes (~1.6 mPa/s), as confirmed by rheological studies. Gellan was anchored to the bilayer domains through cholesterol, and the polymer chains were distributed onto the outer surface of the bilayer, thus forming a core-shell structure, as suggested by SAXS analyses. The optimal carrier ability of core-shell gellan-transfersomes was established by the high deposition of baicalin in th…
Le prix des paysages périurbains
2007
L'évaluation économique du prix des paysages périurbains utilise des analyses géographiques (occupation des sols, composition paysagère, distance à des biens paysagers, paysages vus : champ de vision, objets, formes). L'article fait le point sur la littérature en matière de méthode et de résultats et présente l'estimation du prix d'attributs paysagers dans la ceinture périurbaine de Dijon.
Outer suburbs, car dependence and residential choice in France, In: Planning After Petroleum: Preparing Cities for the Age Beyond Oil
2016
In a discussion of the findings of extensive research of everyday household practices, this chapter suggests effective policy responses to increasingly more expensive petrol prices. Our research involved interviews, observations and analyses of low-income households adapting their mobility practices and residential locations within highly car-dependent urban environments. The chapter examines two main types of practices of households in car-dependent outer suburbs: either households opt 'to stay', forgoing sustained mobility and a varied range of activities, or they choose 'to go' and relocate in areas where travel costs are less of a burden on their budgets. Our research analyzed statistic…
The value of peri-urban landscapes in a French real estate market
2011
Co-éditions : Wiley, Hoboken, USA; International audience; Nous étudions le prix hédoniste de paysages périurbains dans la région de Dijon (France) à partir de données individuelles de transactions de maisons, géoréférencées pour permettre de les apparier avec des données géographiques sur les paysages. Des variables paysagères sont constituées en calculant le paysage vu depuis le sol autour de ces maisons : plans de vision selon leur éloignement (six horizons sont distingués) et contenu de ceux-ci décliné en douze types d’occupation du sol. Les résultats montrent que la vue proprement dite compte, car les objets présents à proximité des maisons mais non vus ont un prix hédoniste inférieur …
Topical anti-inflammatory activity of some Asian medicinal plants used in dermatological disorders.
2001
The topical anti-inflammatory activity of extracts from Cassia angustifolia, Rheum palmatum, Coptis chinensis, Phellodendron amurense and Scutellaria baicalensis, plants used in traditional East Asian medicine against different skin disorders, was studied. Though in different degree, all the extracts significantly inhibited the edema induced by 12-O-tetradecanoylphorbol-13-acetate (TPA), in both single or multiple application, oxazolone, and arachidonic acid (AA). None of the extracts inhibited in vitro the activity of phospholipase A(2) (PLA(2)) from Naja naja.
Inhibition of skin inflammation by baicalin ultradeformable vesicles.
2016
The topical efficacy of baicalin, a natural flavonoid isolated from Scutellaria baicalensis Georgi, which has several beneficial properties, such as antioxidative, antiviral, anti-inflammatory and antiproliferative, is hindered by its poor aqueous solubility and low skin permeability. Therefore, its incorporation into appropriate phospholipid vesicles could be a useful tool to improve its local activity. To this purpose, baicalin at increasing concentrations up to saturation, was incorporated in ultradeformable vesicles, which were small in size (∼67nm), monodispersed (PI<0.19) and biocompatible, regardless of the concentration of baicalin, as confirmed by in vitro studies using fibroblasts…
Effect of ouabain and furosemide on erythrocyte sodium and phosphate transport.
1981
The effects of ouabain and furosemide on the unidirectional efflux of sodium and phosphate ions were studied in freshly drawn human red blood cells (RBCs). In the presence of physiologic concentrations of sodium and potassium the rate of sodium efflux was reduced by 74% due to ouabain sensitivity. Furosemide (1.0 mmol/l) reduced ouabain-insensitive sodium transport rate by a further 50%. Thus, 13% of total sodium efflux was inhibited by furosemide when ouabain was present. In the absence of ouabain, however, furosemide inhibited 31% of total sodium transport, indicating that it also affected ouabain-sensitive sodium efflux. Phosphate transfer of RBCs was almost 1.0 mmol/l RBCs per hour. Ery…
