An African Muslim Saint and his Followers in France

This paper explores the practice of Islam among a relatively understudied group of Muslim migrants in France, the Halpulaaren, some of whom have been living in France for more than three decades. Drawing on field research in Senegal, Mali and France, the author considers the contexts for Halpulaaren migration to France, including the West African background to such migration and the situation migrants face in France. The author focuses on a Halpulaaren Muslim religious leader from Senegal, Mansour Baro, who has a reputation as a living Muslim saint, and his followers in France. Tierno Mansour is one of a handful of the most esteemed leaders of the Tijaniyya Sufi order in Senegal. The appeal of this saint, who annually visits Europe, for his followers in France is examined in order to try and understand some of the ways of being Muslim in the shadow of the global city with both its promises and constraints.

Pregnancy Outcome and Placenta Pathology in Plasmodium berghei ANKA Infected Mice Reproduce the Pathogenesis of Severe Malaria in Pregnant Women

Pregnancy-associated malaria (PAM) is expressed in a range of clinical complications that include increased disease severity in pregnant women, decreased fetal viability, intra-uterine growth retardation, low birth weight and infant mortality. The physiopathology of malaria in pregnancy is difficult to scrutinize and attempts were made in the past to use animal models for pregnancy malaria studies. Here, we describe a comprehensive mouse experimental model that recapitulates many of the pathological and clinical features typical of human severe malaria in pregnancy. We used P. berghei ANKA-GFP infection during pregnancy to evoke a prominent inflammatory response in the placenta that entails CD11b mononuclear infiltration, up-regulation of MIP-1 alpha chemokine and is associated with marked reduction of placental vascular spaces. Placenta pathology was associated with decreased fetal viability, intra-uterine growth retardation, gross post-natal growth impairment and increased disease severity in pregnant females. Moreover, we provide evidence that CSA and HA, known to mediate P. falciparum adhesion to human placenta, are also involved in mouse placental malaria infection. We propose that reduction of maternal blood flow in the placenta is a key pathogenic factor in murine pregnancy malaria and we hypothesize that exacerbated innate inflammatory responses to Plasmodium infected red blood cells trigger severe placenta pathology. This experimental model provides an opportunity to identify cell and molecular components of severe PAM pathogenesis and to investigate the inflammatory response that leads to the observed fetal and placental blood circulation abnormalities
