Beef heart mitochondrial ATPase (F1) catalyzes the hydrolysis of the ATP analog adenyl-5-yl imidodiphosphate (AMP-PNP). The reaction products are inorganic phosphate and adenyl-5-yl phosphoramidate (AMP-PN) as determined by HPLC analysis. The hydrolysis occurs in both the presence and absence of added divalent metal ions and is stimulated by potassium. The kinetic properties of the hydrolytic r...

Effective Tree Chiral Lagrangian is interpreted as a power series expansion of the kinematical variables. In the presence of the strong interaction this expansion is valid below the unitarity cut, hence in the unphysical region. Consequences of this reinterpretation of the Chiral Lagrangian are analysed for the relation between K − π and K − 2π transitions. ∗unité propre 014 du CNRS

DC-SIGN is a C-type lectin, expressed on a dendritic cell subset. It is able to bind ICAM3 and HIV gp120 in a calcium-dependent manner. Here we report the genomic organization of DC-SIGN and map it to chromosome 19p13 adjacent to the C-type lectin CD23 (FcepsilonRII). We also report a novel, closely linked gene, DC-SIGNR, which shows 73% identity to DC-SIGN at the nucleic acid level and a simil...

Identity has been a major factor in establishing and maintaining traditional forms of dwellings and settlements. Today this connection between people and place has been fragmented because of social, economic and technological forces. An examination of the hill town of Giove in 1987 revealed how twentieth century people can identify with places built long ago. The author's "reading" of Giove and...

It has often been observed that many jokes rely on the audience reinterpreting the initial part of the joke once the punchline is encountered. In order to elaborate on this account, we outline how these reinterpretations may happen in various ways. The examples we consider suggest that the generalisation is best stated not in terms of syntactic or even semantic forms, since the same mechanism s...

Monitoring (tracking and surveillance) of children's behavior is considered an essential parenting skill. Numerous studies show that well-monitored youths are less involved in delinquency and other normbreaking behaviors, and scholars conclude that parents should track their children more carefully. This study questions that conclusion. We point out that monitoring measures typically assess par...
