Alteration of the extracellular matrix (ECM) is one major events in pathogenesis brain lesions following ischemic stroke. Heparan sulfate mimetics (HSm) are synthetic pharmacologically active polysaccharides that promote ECM remodeling and tissue regeneration various types lesions. HSm bind to growth factors, protect them from enzymatic degradation increase their bioavailability, which promotes repair. As altered during stroke have been shown restore ECM, we investigated potential HSm4131...

ABSTRACT The Triffa Plain is the most productive irrigated agricultural zone in north‐eastern Morocco. Irrigated agriculture (semi‐)arid regions may exert different pressures on soil resources, but northern Africa these are often poorly documented. A field survey conducted 2005 to assess quality region focuses soil's physico‐chemical parameters and analyses their spatial dependency a regional scale. As of soils light‐textured, with poor organic matter content slightly basic pH, they...

Le dispositif BRAMM (Biosurveillance des retombées atmosphériques métalliques par les mousses) est un français de surveillance la qualité l’air à partir mousses terrestres. Il permet cartographier, l’échelle nationale (France métropolitaine), niveaux concentrations en contaminants (éléments et azote) accumulés dans prélevées milieu rural forestier. suit aussi évolutions temporelles dépôts grâce données d’observation longue durée (sur quinze ans). Quatre campagnes françaises ont été réalisées...

Abstract Tendons are composed of type I collagen fibrils and specialized extracellular matrix (ECM) proteins that hierarchically organized to transmit forces from muscle bone. Reliable affordable models human tendon constructs requested serve surgical treatment after injury in vitro pharmacological testing. Here, using adipose stromal cells embedded a 3D type-I submitted static uniaxial geometrical constraint, we generated assessed their mechanical properties gene expression for up 21 days...

Polychlorinated biphenyls (PCBs) are persistent organic pollutants accumulating along the food chain, and particularly in fish. Consequently, European Commission has set regulatory limits for PCBs both sea- freshwater Focusing on fish, French Agency Food Environmental Occupational Health & Safety developed a method to determine areas France where consumption of locally caught fish is not recommended due PCB contamination. To these potential health concern, an existing statistical model...
