    Hairy Cell Leukemia and HCL-Like Disorders: Diagnosis and Treatment
    Leucémie à Tricholeucocytes et Autres Proliférations à Cellules Chevelues: Diagnostic et Traitement

    Elsa Maitre, Xavier Troussard*

    Oncologie, Vol.24, No.1, pp. 3-24, 2022, DOI:10.32604/oncologie.2022.021490

    Abstract Hairy cell leukemia (LT) accounts for 2% of all leukemias. The diagnosis is based on the presence in the blood and/ or the marrow of hairy cells expressing CD103, CD123, CD11c and CD25. The BRAFV600E mutation, a molecular marker of the disease, is present in more than 80% of cases. LT should be distinguished from other chronic B-cell lymphoproliferative disorders, including the variant form of hairy cell leukemia (HCL-V) and diffuse splenic red pulp lymphoma (DSRPL). Progress has recently been made in the management of patients. The purine analogues (PNAs) in monotherapy, deoxycoformycin (DCF) or 2-chloro-deoxyadenosine (CDA), remain the first-line… More >

    The Effect of Bamboo Charcoal Application on Soil Nutrients and Heavy Metals in Rice

    Guangyue Cai1, Juanli Tu2, Songhao Li3, Yifei Ruan3, Qifeng Wu3, Jiasen Wu1,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.6, pp. 1245-1256, 2022, DOI:10.32604/phyton.2022.019599

    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 bamboo charcoal application), BC1 (2500 kg⋅ha−1),… More >

    HCl-Induced Hg0 Transformation over CuMn2O4 Sorbent

    Aijia Zhang, Yingju Yang, Jing Liu*, Junyan Ding

    Energy Engineering, Vol.119, No.2, pp. 499-510, 2022, DOI:10.32604/ee.2022.015504

    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 >

    Preliminary Optimization and Kinetics of SnCl2-HCl Catalyzed Hydrothermal Conversion of Microcrystalline Cellulose to Levulinic Acid

    Dexby de Guzman, Rizalinda de Leon*

    Journal of Renewable Materials, Vol.9, No.1, pp. 145-162, 2021, DOI:10.32604/jrm.2021.011646

    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 (Bronsted acids). Evaluation… More >
