Les caractéristiques de l'acte d'achat et la logique du marketing amont

International audienceDe nombreux travaux l'indiquent, les similitudes qui apparaissent entre la vente et l'achat garantissent la pertinence du concept de marketing amont. Cependant, les particularités de l'acte d'achat confirent certaines spécificités au marketing de l'acheteur. La logique d'action qui le caractérise comporte incontestablement une composante adaptative;mais elle doit également s'appuyer sur l'utilisation de mécanismes de pouvoir. La stimulation de la concurrence entre les fournisseurs et le partenariat sont les instruments les plus puissants dont les entreprises disposent pour inciter les fournisseurs à tenir compte de leurs besoins;employés sans coercition ils constituent les principaux ressorts de l'action marketing des acheteurs

A dyserythropoietic anemia associated with homozygous Hb Plasencia [α125(H8)Leu→Arg (α2)] (HBA2:c.377T>G), a variant with an unstable α chain.

A female patient of Portuguese origin, who was born to consanguineous parents, presented with moderate anemia, mild jaundice and splenomegaly. Bone marrow aspiration showed an erythroid hyperplasia and binucleate erythroblasts, evoking a congenital dyserythropoietic anemia, type II (CDA II). Although microcytosis cast some doubt on the diagnosis, investigation was pursued along this line. The CDA II was finally ruled out as underglycosylation of band 3, remnants of endoplasmic reticulum cisternae and mutations in the SEC23B gene were all missing. On the other hand, analysis of the α-globin genes showed a base substitution at codon 125 (CTG→CGG) of the α2-globin gene, ascertaining a homozygosity for Hb Plasencia (HBA2:c.377T>G). This variant has an unstable α chain. In the absence of a thorough work-up, dyserythropoietic anemia associated with hemoglobin (Hb) variants having a moderately unstable α chain, may be mistaken for CDA II
