Relations génétiques entre les populations de mils sauvages et cultivés : résultats d'une enquête au Mali

Genetic relationships between wild and domestic populations of pearl millet : results from a survey in Mali. Pearl millet (Pennisetum typhoïdes) seeds were collected from Mali in november 1985. ORSTOM and IBPGR having already obtained exhaustive collections of various forms of pearl millet, the aim of this project was to collect a limited number of samples from areas where pearl millets of domestic, wild and intermediate types (chibras, hybrids between wild and domestic types) are found in a sympatric or allopatric situation. The three types coexist with non sexual barriers. The samples were collected in three areas : — Nioro du Sahel ; — Bandiagara ; — Gourma-Rahrous. Enquiries carried out within the local population led to the knowledge of the growing habits (cultivation, seed preparation, behaviour towards chibras or wild types) as well as the feeding habits and the usual names for the various types of pearl millet. This information gives a better view of the related evolution within wild and domestic populations of pearl millet in precise ecological conditions.Une collecte de semences de mil (Pennisetum typhoïdes) a été réalisée au Mali en novembre 1985. L'ORSTOM et L'IBPGR ayant déjà réalisé des collectes exhaustives de diverses formes de mil, le but de cette prospection était d'effectuer un petit nombre de prélèvements dans des régions où des mils cultivés, sauvages et intermédiaires (chibras, hybrides entre les formes sauvages et cultivées) se trouvent en situation sympatrique ou allopatrique. Ces trois formes coexistent sans barrière reproductive. Les prélèvements ont été effectués dans trois régions : — Nioro du Sahel ; — Bandiagara ; — Gourma-Rahrous. Des enquêtes, menées chez les paysans, ont permis de connaître les pratiques culturales (culture, préparation des semences, attitude vis-à-vis des chibras ou de sauvages) ainsi que les habitudes alimentaires et les noms vernaculaires des différentes formes de mil. Ces indications permettent de mieux cerner la coévolution des populations de mil sauvage et cultivé dans des situations écologiques précises.Sandmeier Michel, Pilate-André Sophie, Pernes Jean.

Données préliminaires pour la réintroduction et la culture du millet Setaria en France

This short review describes various aspects of foxtail millet Setaria italica, particularly : its origin, traditional and modern cultural practices in China and France, comparisons between French and Chinese varieties, and floral biology. Some Chinese varieties appear to be well adapted to modem French agriculture. Therefore, extension of millet culture in France might be favorable reconsidered.Une revue succincte présente différents aspects du millet Setaria italica : origines, pratiques culturales traditionnelles et actuelles en Chine et en France, comparaison de variétés chinoises et françaises, biologie florale. Des variétés chinoises semblent directement utilisables en France. Ces informations permettent de présenter les perspectives pour une nouvelle extension du millet en France.Brabant P., Belliard Jacques, Métailié Georges, Nguyen Van E., Poirier S., Poirier B., Pernes Jean.

Diagnostic accuracy of prospective ECG gated coronary computed tomography on a 256 slices scanner: Daily practice experience

To determine the accuracy of prospective ECG-gated computed tomography coronary angiography (CTCA) using 256-slice scanner for detecting significant coronary artery disease (CAD) and to quantitatively estimate lumen narrowing with CTCA in comparison to invasive coronary angiography (ICA). Methods: This study included 109 consecutive patients who had ICA on the basis of a previous CTCA (within 60 days) for clinical suspicious of CAD. All CTCA scans were performed with a 256-slice scanner using prospective ECG-gated image acquisition. The presence of stenosis ⩾50%, measured by QCA for ICA and Visual assessment for CTCA, was considered significant stenosis. Results: Obstructive CAD was present in 73.4% of patients. On patient-based analysis, the sensitivity of CTCA was 98%, specificity 83%, PPV 94% and NPV 92%. For segment-based analysis, a total of 1584 segments were analyzed with a sensitivity of 89%, specificity 98%, PPV 85% and NPV 99%. High correlation was observed between degrees of luminal stenosis assessed by CTCA in comparison to QCA in all segments (r2 = 0.961). There was high agreement between observers regarding the presence of significant luminal stenosis (k = 0.78) and good correlation for percentage of luminal stenosis (r = 0.68, p < 0.001) between both readers. Conclusions: In a highly prevalence diseased population, prospective ECG-gated CTCA using 256-slice scanner is highly accurate for detection and quantification of the degree of coronary luminal stenosis in comparison to ICA

Delineation of 15q13.3 microdeletions.

International audienceThe increasing use of array-comparative genomic hybridization (array-CGH) to identify copy number variations (CNVs) in patients with developmental delay (DD), mental retardation and/or dysmorphic features has allowed the recent recognition of numerous genomic imbalances, including the 15q13.3 microdeletion. Patients with this microdeletion generally present with relatively consistent breakpoints at BP4 and BP5, which include the CHRNA7 gene. About 100 index cases have been reported since the first publication in 2008. This large number of patients ascertained through highly variable samples has been necessary to describe the full phenotypic spectrum of this microdeletion, ranging from mental retardation with dysmorphic features, epilepsy, neuropsychiatric disturbances with or without cognitive impairment to complete absence of anomalies. Here, we describe a collaborative study reporting a new cohort of 12 index patients and 13 relatives carrying a heterozygous BP4-BP5 microdeletion out of a series of 4625 patients screened by array-CGH for DD. We confirm the clinical expressivity of the disease as well as the incomplete penetrance in seven families. We showed through a review of the literature that males are more likely to be symptomatic. Sequence analysis of CHRNA7 yielded no data to support the unmasking of recessive variants as a cause of phenotypic variability. We also report the first patient carrying a 15q13.3 homozygous microdeletion inherited from both parents. He had severe epileptic encephalopathy with retinopathy, autistic features and choreoathetosis. Besides the classical approximately 1.5 Mb BP4-BP5 microdeletion, we also describe three index patients and two relatives with a smaller 500 kb microdeletion, including the CHRNA7 gene
