Publication date: Available online 3 June 2018Source: Journal of Hazardous MaterialsAuthor(s): Siqi Liu, Tao Cui, Anlin Xu, Weiqing Han, Jiansheng Li, Xiuyun Sun, Jinyou Shen, Lianjun WangAbstractIn order to break the high operating cost bottleneck of electrochemical treatment of aqueous flutriafol (FTF), an emerging fungicide, a novel three-dimensional ordered macroporous PbO2 (3DOM-PbO2) filter was designed to facilitate mass transfer. The effects of operating parameters, including current density, flow rate and initial concentration on FTF electrooxidation performance were investigated using conventional flat Ti/PbO2 (F-Ti/PbO2) and 3DOM-PbO2 filters, with primary objective being the development of appropriate parameters for FTF treatment. The results indicated that the FTF removal efficiency on 3DOM-PbO2 filter was improved by 2.8 times compared to that on F-Ti/PbO2 at 5 mA cm-2, 10 ml s-1 and 100 mg L-1 FTF. The corresponding electrical energy consumption was reduced by 2.7 times, ` TOC removal and mineralization current efficiency were enhanced by 4.9 and 4.8 times, respectively. Furthermore, aromatic intermediates, nitrogenous compounds and carboxylic acids were identified as main byproducts using experimental method combined with quantum chemical calculations. Then, a possible pathway of FTF degradation on 3DOM-PbO2 was proposed. Finally, the acute toxicity results showed that toxicity of the byproducts first increases and then decreases through the proposed rou...
CONCLUSION: The remains in the LTB tomb were not a traditional nuclear family (father, mother and son/daughter) and it was probably a tomb where two women, one of them pregnant, were buried. PMID: 30027753 [PubMed - as supplied by publisher]

Authors: Shin KH, Lee HJ, Kim HH, Hong YJ, Park KU, Kim MJ, Kwon JR, Choi YS, Kim JN Abstract Frequencies of red blood cell (RBC) blood group antigens differ by ethnicity. Since the number of immigrants is increasing in Korea, RBC antigens should be assessed in children/youths with parents of different ethnicities to ensure safe transfusions. We investigated the frequency of RBC antigens, except for ABO and RhD, in 382 children and youths with parents having Korean and non-Korean ethnicities. Subjects were divided into those with ethnically Korean parents (Korean group; N=252) and those with at least one parent of ...
CONCLUSIONS: rs3761549, rs5902434, and rs2232365 are associated with an increased risk of acute GVHD and decreased risk of post-HSCT infection. PMID: 30027704 [PubMed - in process]
CONCLUSIONS: Our algorithm omitting weak D testing in D- patients with C-E- phenotype may be a cost-effective testing strategy in Korea. PMID: 30027703 [PubMed - in process]
