We have recently established that enhancement of intracellular calcium cycling and contraction in response to beta2-adrenergic receptor (beta2-AR) stimulation exclusively relies on the activation of the cytosolic phospholipase A2 (cPLA2) and arachidonic acid production, via a pertussis toxin-sensitive G protein (possibly Gi), in embryonic chick(More)
In Djohong in the wet season the prevalence of malaria is 17.5% for Plasmodium falciparum and 1.1% for Plasmodium malariae. In children 2 to 9 years of age the plasmodic index is 38.6% (mesoendemicity) for the children of the peasants and 9.4% for those belonging to other socioeconomical groups. In infants less than 12 months old, the plasmodic index is(More)
Niger is a Sahelian country of 1,267,000 km2 and 11 M inhabitants (84% living in rural area). The national seroprevalence of the HIV infection is low (2.08% in urban area and 0. 64% in rural area). Because of limited resources, laboratories and qualified personnel are scarce, so the classical strategy using ELISA methods to diagnose HIV is available only in(More)
