Retour sur l'Europe chinoise

Tandis que les modes de la chinoiserie au XVIIIe et du japonisme au XIXe siècles ont fait l'objet d'innombrables publications, pour ce qui est des périodes antérieures les apports de l'Orient ont été généralement occultés par les historiens de l'art occidentaux. Cette véritable tache aveugle est-elle le fruit de l'ignorance ou le signe d'un chauvinisme européocentrique et anachronique ?¦On rappellera d'abord l'importance et la fréquence des contacts séculaires le long des routes de la soie, parcourues par les missionnaires et les marchands. Deux études de cas serviront ensuite à illustrer les phénomènes d'hybridation et de métissage qui résultent d'emprunts formels. Dans la peinture de paysage, la présence de nuages ou de montagnes chinoises en Europe dès le XVe siècle témoigne de migrations d'est en ouest. Quant au motif architectural de la porte en forme de gueule de monstre, présent du jardin de Bomarzo au Palazzo Zuccari de Rome, il semble également relever d'une source iconographique exotique, celle du kala indonésien.

Safety and effectiveness of amphotericin B deoxycholate for the treatment of visceral leishmaniasis in Uganda

Between September 2003 and April 2004, the supply of antimonial drugs to Amudat Hospital, in north-eastern Uganda, was interrupted and all cases of visceral leishmaniasis presenting at the hospital could only be treated with amphotericin B deoxycholate (AmB). This allowed the safety and effectiveness of the AmB to be evaluated, in comparison with an historical cohort of patients treated, at the same hospital, with meglumine antimoniate (Sb-V). Demographic and clinical data were collected before and after treatment. Adverse effects were recorded passively in all the subjects, and actively, using a standardized questionnaire, in a sub-group of the patients given AmB. The in-hospital case-fatality 'rates' were 4.8% [95% confidence interval (CI) =2.4%-8.8%] among the 210 patients treated with AmB and 3.7% (CI=1.4%-7.9%) among the 161 patients treated with Sb-V (P>0.20). Adverse effects requiring treatment interruption were rare in both cohorts. Treatment failures (i.e. non-responses or relapses) were observed in 2.9% (CI= 1.2%-6.4%) of the patients treated with AmB and 1.2% (CI=0.1%-4.4%) of the patients treated with Sb-V (P>0.20). For the treatment of visceral leishmaniasis in Uganda, AmB therefore had a similar effectiveness and safety profile to that of meglumine antimoniate.

The immunological, environmental, and phylogenetic perpetrators of metastatic leishmaniasis.

Cutaneous leishmaniases have persisted for centuries as chronically disfiguring parasitic infections affecting millions of people across the subtropics. Symptoms range from the more prevalent single, self-healing cutaneous lesion to a persistent, metastatic disease, where ulcerations and granulomatous nodules can affect multiple secondary sites of the skin and delicate facial mucosa, even sometimes diffusing throughout the cutaneous system as a papular rash. The basis for such diverse pathologies is multifactorial, ranging from parasite phylogeny to host immunocompetence and various environmental factors. Although complex, these pathologies often prey on weaknesses in the innate immune system and its pattern recognition receptors. This review explores the observed and potential associations among the multifactorial perpetrators of infectious metastasis and components of the innate immune system.

Tools and data services registry: a community effort to document bioinformatics resources.

Life sciences are yielding huge data sets that underpin scientific discoveries fundamental to improvement in human health, agriculture and the environment. In support of these discoveries, a plethora of databases and tools are deployed, in technically complex and diverse implementations, across a spectrum of scientific disciplines. The corpus of documentation of these resources is fragmented across the Web, with much redundancy, and has lacked a common standard of information. The outcome is that scientists must often struggle to find, understand, compare and use the best resources for the task at hand.Here we present a community-driven curation effort, supported by ELIXIR-the European infrastructure for biological information-that aspires to a comprehensive and consistent registry of information about bioinformatics resources. The sustainable upkeep of this Tools and Data Services Registry is assured by a curation effort driven by and tailored to local needs, and shared amongst a network of engaged partners.As of November 2015, the registry includes 1785 resources, with depositions from 126 individual registrations including 52 institutional providers and 74 individuals. With community support, the registry can become a standard for dissemination of information about bioinformatics resources: we welcome everyone to join us in this common endeavour. The registry is freely available at https://bio.tools.
