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...
Authors: Mukai M, Komori K, Oka T Abstract The advent of new chemotherapeutic and immunotherapeutic treatments has markedly improved outcomes in patients with cancer. However, increasing numbers of elderly patients with cancer and prolonged periods of treatment have made the management of cardiovascular complications and treatment-induced cardiotoxicity an important concern, and onco-cardiology has received increasing attention. The number of patients with cardiotoxicity, particularly atherosclerotic lesions, and the usage of angiogenesis inhibitors have increased, making the involvement of onco-cardiologists essen...
CONCLUSION: In a relatively young but high-risk population, a lipoprotein profile predominated by triglyceride-rich lipoproteins was associated with increased risk of CAC, while one predominated by HDL lipoproteins offered modest protection. Lipoprotein sub-fraction analysis may help to further discriminate patients who require more intensive cardiovascular work-up and treatment. PMID: 30224606 [PubMed - as supplied by publisher]
Conclusion: DRT is inversely associated with UFR in CHD patients. Whether a high UFR should be recommended to reduce the DRT needs to be elucidated through an adequate prospective randomized study.Blood Purif
ConclusionWe have consolidated a Portuguese version of the European Anatomical Terminology of the Internal Nose and Paranasal Sinuses, which will help in the publication of technical announcements, scientific publications and the teaching of the internal anatomical terms of the nose and paranasal sinuses in Brazil.ResumoIntroduçãoA cirurgia endoscópica funcional endonasal é um procedimento cirúrgico frequente entre os otorrinolaringologistas. Em 2014, a Sociedade Europeia de Rinologia publicou o “Documento Europeu para Posicionamento sobre a Terminologia Anatômica Interna do N...
