| In the 1980s, the technical pattern of production in agriculture changed due to the increasing design of genetically modified plants. Modern biotechnology thrived on events requiring certain thresholds of scientific and technological skills as well as scale economies usually seen in developed countries. The mergers and acquisitions during the mid-1990s led to a world-wide oligopoly composed of very few agri-biotechnological mega-corporations and the literature discusses the impact of the mergers and acquisitions on the agriculture of developing countries with comparative advantages in agriculture. This paper analyzes the world-wide process of agri-biotechnological mega-corporation mergers and acquisitions as well as its impact and interrelationships with... |

| To assess relationships between neuropeptide-binding sites and receptor proteins in rat brain, the distribution of radioautographically labeled somatostatin and neurotensin-binding sites was compared to that of immunolabeled sst2A and NTRH receptor subtypes, respectively. By light microscopy, immunoreactive sst2A receptors were either confined to neuronal perikarya and dendrites or diffusely distributed in tissue. By electron microscopy, areas expressing somatodendritic sst2A receptors displayed only low proportions of membrane-associated, as compared to intracellular, receptors. Conversely, regions displaying diffuse sst2A labeling exhibited higher proportions of membrane-associated than intracellular receptors. Furthermore, the former showed only low... |
