The AMMA mulid network for aerosol characterization in West Africa

Three ground based portable low power consumption microlidars (MULID) have been built and deployed at three remote sites in Banizoumbou (Niger), Cinzana (Mali) and M'Bour (Senegal) in the framework of the African Monsoon Multidisciplinary Analyses (AMMA) project for the characterization of aerosols optical properties. A description of the instrument and a discussion of the data inversion method, including a careful analysis of measurement uncertainties (systematic and statistical errors) are presented. Some case studies of typical lidar profiles observed over the Banizoumbou site during 2006 are shown and discussed with respect to the AERONET 7-day back-trajectories and the biomass burning emissions from the Combustion Emission database for the AMMA campaign

Germline mutations in ETV6 are associated with thrombocytopenia, red cell macrocytosis and predisposition to lymphoblastic leukemia

Some familial platelet disorders are associated with predisposition to leukemia, myelodysplastic syndrome (MDS) or dyserythropoietic anemia. We identified a family with autosomal dominant thrombocytopenia, high erythrocyte mean corpuscular volume (MCV) and two occurrences of B cell-precursor acute lymphoblastic leukemia (ALL). Whole-exome sequencing identified a heterozygous single-nucleotide change in ETV6 (ets variant 6), c.641C>T, encoding a p.Pro214Leu substitution in the central domain, segregating with thrombocytopenia and elevated MCV. A screen of 23 families with similar phenotypes identified 2 with ETV6 mutations. One family also had a mutation encoding p.Pro214Leu and one individual with ALL. The other family had a c.1252A>G transition producing a p.Arg418Gly substitution in the DNA-binding domain, with alternative splicing and exon skipping. Functional characterization of these mutations showed aberrant cellular localization of mutant and endogenous ETV6, decreased transcriptional repression and altered megakaryocyte maturation. Our findings underscore a key role for ETV6 in platelet formation and leukemia predisposition

Le cycle des aérosols terrigènes au Sahel : ce qu'AMMA nous a appris

Les aérosols terrigènes sont une composante majeure de l'atmosphère au Sahel. Leurs impacts, notamment sur le climat, les cycles biogéochimiques et la santé, en font un objet d'étude tout à fait d'actualité. Pour quantifier ces impacts, il faut d'abord connaître précisément le cycle de ces aérosols (émission, transport, dépôt) et identifier les facteurs qui le contrôlent afin de le modéliser. Dans cet objectif, des expériences intensives ou sur le long terme, faisant appel à des dispositifs de mesure originaux, ont été mises en place grâce au programme AMMA. Cet article rassemble les principaux résultats acquis au cours de ces campagnes. Ils ont permis de mettre en évidence le rôle des états de surface et de la dynamique atmosphérique sur les concentrations en aérosols terrigènes au Sahel et plus particulièrement la contribution majeure des apports sahariens à ces concentrations.Dust emitted from soil by wind erosion is a main atmospheric compound in the Sahel. Its impacts on climate, biogeochemical cycles and human health explain the present increasing interest of this topic. The different terms of the dust life cycle (emission, transport, deposition) and the parameters controlling this cycle have to be understood and described. The following step is to model the dust cycle to quantify these impacts. In this objective, intensive and long term observing periods, using original experimental set up, were implemented in the frame of AMMA project. This paper summarizes the most significant results obtained during these campaigns. They highlight the major role played by surface features and atmospheric dynamics on dust concentrations in the Sahel as well as the major contribution of Saharan emissions to the Sahelian dust load

Effect of Drying Methods on Lutein Content and Recovery by Supercritical Extraction from the Microalga Muriellopsis sp. (MCH35) Cultivated in the Arid North of Chile

In this study, we determined the effect of drying on extraction kinetics, yield, and lutein content and recovery of the microalga Muriellopsis sp. (MCH35) using the supercritical fluid extraction (SFE) process. The strain was cultivated in an open-raceways reactor in the presence of seawater culture media and arid outdoor conditions in the north of Chile. Spray-drying (SD) and freeze-drying (FD) techniques were used for dehydrating the microalgal biomass. Extraction experiments were performed by using Box-Behnken designs, and the parameters were studied: pressure (30–50 MPa), temperature (40–70 °C), and co-solvent (0–30% ethanol), with a CO2 flow rate of 3.62 g/min for 60 min. Spline linear model was applied in the central point of the experimental design to obtain an overall extraction curve and to reveal extraction kinetics involved in the SFE process. A significant increase in all variables was observed when the level of ethanol (15–30% v/v) was increased. However, temperature and pressure were non-significant parameters in the SFE process. The FD method showed an increase in lutein content and recovery by 0.3–2.5-fold more than the SD method. Overall, Muriellopsis sp. (MCH35) is a potential candidate for cost-effective lutein production, especially in desert areas and for different biotechnological applications

Overview of the Dust and Biomass-burning Experiment and African Monsoon Multidisciplinary Analysis Special Observing Period-0

International audienceThe African Monsoon Multidisciplinary Analysis (AMMA) is a majorinternational campaign investigating far-reaching aspects of the African monsoon,climate and the hydrological cycle. A special observing period was established for thedry season (SOP0) with a focus on aerosol and radiation measurements. SOP0 tookplace during January and February 2006 and involved several ground-basedmeasurement sites across west Africa. These were augmented by aircraftmeasurements made by the Facility for Airborne Atmospheric Measurements (FAAM)aircraft during the Dust and Biomass-burning Experiment (DABEX), measurementsfrom an ultralight aircraft, and dedicated modeling efforts. We provide an overview ofthese measurement and modeling studies together with an analysis of themeteorological conditions that determined the aerosol transport and link the resultstogether to provide a balanced synthesis. The biomass burning aerosol wassignificantly more absorbing than that measured in other areas and, unlike industrialareas, the ratio of excess carbon monoxide to organic carbon was invariant, which maybe owing to interaction between the organic carbon and mineral dust aerosol. Themineral dust aerosol in situ filter measurements close to Niamey reveals very littleabsorption, while other measurements and remote sensing inversions suggestsignificantly more absorption. The influence of both mineral dust and biomass burningaerosol on the radiation budget is significant throughout the period, implying thatmeteorological models should include their radiative effects for accurate weatherforecasts and climate simulations. Generally, the operational meteorological modelsthat simulate the production and transport of mineral dust show skill at lead times of5 days or more. Climate models that need to accurately simulate the vertical profilesof both anthropogenic and natural aerosols to accurately represent the direct andindirect effects of aerosols appear to do a reasonable job, although the magnitude ofthe aerosol scattering is strongly dependent upon the emission data set
