    International perspectives on backwards vertical integration

    No full text
    International audienceThis chapter provides a broad understanding of the motivations and debates related to vertical integration backwards, through concrete examples or practical cases. Vertical integration backwards in the wine industry was extensively discussed in the literature (see, e.g. Sidlovits and Kator 2007). However, those contributions focus on one region or country or a particular type of firm (e.g. wine co-operatives). Without pretending to cover all the dimensions of vertical integration, we introduce hereafter, through several examples, the causes or consequences that lead firms to practice vertical integration

    Transcriptional changes in the hookworm, Ancylostoma caninum, during the transition from a free-living to a parasitic larva

    Background: Third-stage larvae (L3) of the canine hookworm, Ancylostoma caninum, undergo arrested development preceding transmission to a host. Many of the mRNAs up-regulated at this stage are likely to encode proteins that facilitate the transition from a free- living to a parasitic larva. The initial phase of mammalian host invasion by A. caninum L3 (herein termed "activation'') can be mimicked in vitro by culturing L3 in serum-containing medium
