Title: Impeller for centrifugal crushers with vertical axis and method for making same
Inventor: PONCIN CLAUDE
IPC: B02C13/28
Filed: 2000-08-02
Abstract: Throw shoe for centrifugal-type crushers with a vertical shaft.   Initially, i.e. when it is first used, this throw shoe (1) is not provided with pockets or cavities, but it is provided on its working side (5) with a reinforcement structure (4) made out of a composite material, obtained from an iron-based alloy and highly wear-resistant ceramic tiles, said reinforcement structure being formed in situ when the throw shoe is being cast by infiltration of the liquid metal used to form the body of the piece in a mass of ceramic tiles and binder.     The working wear automatically results in the formation of pockets or cavities which, by filling up with the crushed material, exert a protection function against shocks.

Abstract: A suspension adjustment device for adjusting both camber and caster of a wheel is provided. A suspension control arm is mounted between a pair of vehicle frame support members using a single fastener. Cams are disposed on either end of the fastener. The cams rotate in grooves defined in the vehicle frame support members and cause the fastener to move inboard or outboard in slots defined in the frame support members in order to adjust wheel camber. Shims are disposed about the fastener on either side of the control arm between the control arm and the frame support members. Shims are removed from one side and added to the other side to move the control arm in the fore-aft direction and adjust wheel caster. Alternatively, the fore-aft position of the control arm may be adjusted by rotating a threaded bushing disposed about the fastener and extending through the control arm.

Abstract: L'invention concerne la régulation de l'expression de l'activité des lymphocytes cytotoxiques anti-tumeur (CTL) au moyen d'un facteur inhibant la migration des macrophages (MIF). Dans un modèle de souris mettant en oeuvre la tumeur EL4, des splénocytes cultivés provenant de souris sensibilisées à la tumeur sécrètent des taux élevés de facteur MIF, consécutivement à une stimulation d'antigène in vitro. Des splénocytes parallèles traités au moyen de mAb (anticorps monoclonaux) anti-MIF neutralisants ont présenté une augmentation importante au niveau de la réponse des CTL contre des cellules tumorales, comparativement à des cultures témoins traitées au moyen de mAb, avec une expression élevée de IFN .gamma.. L'histologie de tumeurs provenant d'animaux traités au moyen d'un anti-MIF a présenté des augmentations au niveau de l'infiltration des deux lymphocytes T CD4?+¿ et CD8?+¿, ainsi que des cellules tumorales apoptotiques, conformément à l'augmentation observée de l'activité des CTL in vivo par des anti-MIF, précédemment associée à une expression accrue de la chaîne commune .gamma.¿c? du récepteur IL-2 induisant la survie des lymphocytes T CD8?+¿. Des cellules CD8?+¿ de souris porteuses de tumeur traitées au moyen d'un anti-MIF ont présenté une migration accrue en tumeurs des souris témoins. L'invention concerne également des méthodes permettant d'accroître une réponse des CTL par inhibition des MIF.

Abstract: The invention relates to a carrier particle having a diameter of from 5 to 2 0 nm which contains an HDL apolipoprotein, an amphipathic lipid such as a phospholipid, and a drug which is either a hydrophobic drug, amphipathic dru g, or a cationic hydrophilic drug. The carrier particle is formed by a process in which the components are co-sonicated in a buffer. The apolipoprotein is preferably apo A-I or apo A-II. The carrier particle is particularly useful for increasing plasma circulation time of a hydrophobic drug relative to conventional hydrophobic drug carrier particles. Thus, drug efficacy is improved and toxicity of the drug to renal and reticuloendothelial tissues i s reduced. A composition for drug delivery comprises the carrier particle suspended in a pharmaceutically acceptable medium, and is particularly suite d to administration by parenteral infusion, systemic injection, transdermal patch, oral tablet or oral spray.
