Moving ACRoss the Gift Economy and the Market

This paper explores the micro dynamics through which consumption may liberate people from the gift economy, as well as how it may constrain them. It unveils how people negotiate the social expectations of the gift economy and the relational obligations (like social indebtedness) that such a context of exchange entails by subverting the gift, by using the market, and by moving from the gift economy to the market. In other words, it examines how people turn to the market as a means of asserting their agency

The carbohydrate moiety of aminopeptidase N of rabbit intestinal brush-border membrane

AbstractEndoglycosidase F was used to eliminate the N-linked complex glycans from intestinal aminopeptidase N. The glycans which were probably O-linked remaining after the endoglycosidase F treatment exhibited the human blood group A and H determinants expressed in enzymes from A+ or A− rabbits, respectively. The molecular mass estimation of the two types of glycans by SDS-polyacrylamide gel electrophoresis and the sugar composition of aminopeptidase from A+ and A− rabbits strongly suggested the presence of eight N-linked complex glycans and two O-linked oligosaccharides bearing the human group antigenicity
