Neuropeptide Y is implicated in the regulation of feeding in vertebrates, but recent studies in transgenic mice are contradictory. In this issue of Neuron, Wu et al. show a dual role for the Drosophila NPY (dNPF) in the developmental regulation of larval foraging and social behaviors, demonstrating a conserved role for this peptide in complex behaviors.

Sa longue carrière sera universitaire. De 1955 à la fin de son existence, il n’aura jamais cessé de soigner, de chercher, d’enseigner. C’est en 1955, en effet, qu’il devient assistant dans le département d’orthodontie de l’Université d’Indiana à Indianapolis où il vient de terminer sa Maîtrise en orthodontie. Il en assumera la responsabilité de 1956 à 1970 après avoir gravi tous les échelons de...

Oxovanadium(IV), manganese(II) and copper(II) complexes of a Schiff base ligand derived from 2,4-dihydroxyacetophenone and 1,2-diaminocyclohexane have been encapsulated in the nanocavity of zeolite-Y by flexible ligand method and characterized by metal analysis, IR spectroscopic studies and X-ray diffraction patterns. The encapsulated complexes abbreviated here as CuL-Y, MnL-Y and VOL-Y catalyz...
