Abstract La leucémie à tricholeucocytes (LT) représente 2% de l’ensemble des leucémies. Le diagnostic repose sur la présence dans le sang et/ou la moelle de tricholeucocytes: cellules lymphoïdes B au cytoplasme chevelu exprimant le CD103, CD123, CD11c et CD25. La mutation BRAF^V600E, marqueur moléculaire de la maladie, est présente dans plus de 80% des cas. La LT doit être distinguée des autres syndromes lymphoprolifératifs chroniques B, notamment des autres proliférations à cellules chevelues, forme variante de la leucémie à tricholeucocytes (LT-V) et lymphome splé- nique diffus de la pulpe rouge (LSDPR). Des progrès thérapeutiques ont été récemment… More >

Abstract Soil heavy metal pollution is becoming more and more serious. Biomass charcoal application can play an important role in alleviating the toxicity of heavy metals in soils. Compared with other biochar, bamboo charcoal has more unique properties and may have a unique effect on heavy metal pollution. Zhejiang Province of Southeastern China is rich in bamboo resources. However, few studies related to bamboo charcoal application for heavy metal remediation in farmland were reported. In this study, four treatments with different amounts of bamboo charcoal application were set up through a field experiment, namely BC0 (no… More >

Abstract CuMn₂O₄ spinel has been regarded as a highly efficient sorbent for Hg⁰ capture from flue gas. The regenerability and recyclability of CuMn₂O₄ sorbent are mainly associated with the mercury speciation adsorbed on its surface. However, the effect mechanism of HCl on Hg⁰ transformation over CuMn₂O₄ sorbent is still elusive. Experiments were conducted to understand the effect of HCl on Hg⁰ transformation over CuMn₂O₄ sorbent. The results indicate that CuMn₂O₄ sorbent is a mesoporous material and possesses a good thermal stability. CuMn₂O₄ shows >95% Hg⁰ removal efficiency in a wide temperature window of 50–350°C. The favorable electron-transfer environment caused by the… More >

Abstract Levulinic acid (LA) is a platform biorefinery chemical from biomass which can be converted to green solvents, plasticizers, polymer precursors, bio-based cleaning agents, fuels and fuel additives. This study assessed the potential of SnCl₂-based mixed acid systems as catalyst in the hydrothermal conversion of microcrystalline cellulose to levulinic acid. Maximum LA yield of 36.2 mol% was achieved using 0.2 M SnCl₂ concentration at test conditions of 3 h, 180°C and 1% w/v cellulose loading. To reduce precipitate formation and further improve LA yield, the strategy employed was to combine SnCl₂ (a Lewis acid) with conventional mineral acids… More >
