BACKGROUND Drosophila larvae possess only 21 odorant-receptor neurons (ORNs), whereas adults have 1,300. Does this suggest that the larval olfactory system is built according to a different design than its adult counterpart, or is it just a miniature version thereof? RESULTS By genetically labeling single neurons with FLP-out and MARCM techniques, we(More)
The biological availability of amino acids modified by industrial processes has been measured in trials on rats, and their metabolic transit (urinary and faecal excretions, transformation into CO2 and retention in organs) has been studied using molecules labelled with 14C. Maillard reaction products. epsilon-fructose-lysine is not utilized as lysine source.(More)
