    Wei Cui1,2,*, Zhilun Yan1,2, Zhi Tang1,2, Mengyao Xu1,2, Jian Tian1,2, Chengyi Shen1,2

    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.1, pp. 51-60, 2023, DOI:10.32604/fdmp.2023.021499 - 02 August 2022

    Abstract At present, methods for treating tertiary oil recovery wastewater via electro-coagulation are still in their early stage of development. In this study, a device for electro-coagulation wastewater treatment was built and tested in an oil field. The effects that the initial pH value, electrode type, and connection mode have on the coagulation and separation effect were assessed by measuring the mass fraction and turbidity of oil. The results have shown that when the electro-coagulation method is used, the effectiveness of the treatment can be significantly increased in neutral pH conditions (pH = 7), in acidic conditions, and More >

    Recycling of Mud Derived from Backwash Wastewater Coagulation as Magnetic Sodalite Sphere for Zn2+Adsorption

    Suiyi Zhu1, Manhong Ji1, Hongbin Yu1,*, Zhan Qu1, Jiakuan Yang2, Mingxin Huo1, Yi Wang1

    Journal of Renewable Materials, Vol.9, No.9, pp. 1599-1607, 2021, DOI:10.32604/jrm.2021.015189 - 23 April 2021

    Abstract

    Herein, we reported a method to prepare magnetic sodalite sphere by using the mud from backwash wastewater after polyaluminum chloride (PAC) coagulation. The results showed that approximately 100% of Fe in the wastewater was precipitated as flocculent iron mud (FM) by adding PAC. FM was converted to spherical magnetic sodalite (FMP) with a diameter of 3 μm via a facile alkali hydrothermal method without adding Al/Si resources or reductant. The product FMP had the saturated magnetization of 10.9 emu g−1 and high Zn2+ adsorption capacity of 50.6 mg g−1. Without coagulation with PAC, the removal rate of

    ABSTRACT

    Microspheres Modified with the Heparin Increasing the Length of Molecular Linker to Better Capture the Endotoxin

    Qi Dang1, Chun-Gong Li1, Xin-Xin Jin1, Ya-Jin Zhao1, Xiang Wang1,*

    Molecular & Cellular Biomechanics, Vol.16, Suppl.2, pp. 146-146, 2019, DOI:10.32604/mcb.2019.07074

    Abstract Endotoxin is a a very powerful and toxic inflammatory stimulator usually leading to the sepsis occurred. In order to remove endotoxin better through hemoperfusion, it is a pretty choice to increase the length of molecular linker on adsorbents. In this study, we chose the heparin as a molecular linker because of its being anticoagulant linear polysaccharide. Heparin as a linker was covalently immobilized on the chloromethylated polystyrene microspheres (Ps) and then connected with L-phenylalanine (Phe) forming the Ps-Hep-Phe structure to adsorbed endotoxin better. The property of microspheres was characterized by Fourier transform infrared spectroscopy, X-ray More >

    Ketina Arslani1*, Lukas Notz1*, Marzena Zurek1, Matthias Greutmann2, Markus Schwerzmann3, Judith Bouchardy4, Reto Engel5, Christine Attenhofer Jost6, Daniel Tobler1

    Congenital Heart Disease, Vol.13, No.5, pp. 678-684, 2018, DOI:10.1111/chd.12627

    Abstract Background: In adults with congenital heart disease (CHD) and atrial arrhythmias, recommendations for thromboprophylaxis are vague and evidence is lacking. We aimed to identify factors that influence decision-making in daily practice.
    Methods: From the Swiss Adult Congenital HEart disease Registry (SACHER) we identified 241 patients with either atrial fibrillation (Afib) or atrial flutter/intraatrial reentrant tachycardia (Aflut/ IART). The mode of anticoagulation was reviewed. Logistic regression models were used to assess factors that were associated with oral anticoagulation therapy.
    Results: Compared with patients with Aflut/IART, patients with Afib were older (51 ± 16.1 vs 37 ± 16 years, P… More >

    Heparin-induced thrombocytopenia complicating children after the Fontan procedure: Single-center experience and review of the literature

    Uri Pollak1,2,3, David Mishaly3,4, Gili Kenet3,5, Amir Vardi1,3

    Congenital Heart Disease, Vol.13, No.1, pp. 16-25, 2018, DOI:10.1111/chd.12557

    Abstract Heparin-induced thrombocytopenia (HIT) is a life-threatening complication of heparin therapy. The risk for HIT correlates with the cumulative dosage of heparin exposure. In Fontan patients, recurrent systemic anticoagulation, traditionally with heparin, is used to alleviate the thrombotic complications that may occur postoperatively when the venous pressure rises and the systemic venous flow into the pulmonary arteries becomes sluggish, putting them at increased risk. As a pressure gradient-dependent circulation, elevation in systemic venous pressure, most often by venous thrombosis, contributes to circuit failure. Therefore, when HIT complicates patients after the Fontan procedure, it is associated with More >

    Efficiently and Conveniently Heparin/ PEG-PCL Core-Shell Microcarriers Fabrication and Optimization via Coaxial-Electrospraying

    Ying Mao1, Chaojing Li1, Peng Ge1, Fujun Wang1,*, Lu Wang1,*

    Molecular & Cellular Biomechanics, Vol.15, No.3, pp. 143-154, 2018, DOI:10.3970/mcb.2018.03987

    Abstract Heparin/ PEG-PCL core-shell microcarriers were fabricated in one-step via coaxial-electrospraying technology. Optimization of the coaxial-electrospraying processing is by controlling the PEG-PCL concentration, applied voltage, receiving distance, and feed rate. The influence of the electrospray parameters on microsphere morphology was studied by optical microscopy and scanning electron microscopy. The functional groups and components of the electrosprayed microspheres were characterized by Fourier transform infrared spectroscopy (FTIR). Transmission electron microscope (TEM) observation proved the core-shell structure of heparin-loaded PEG-PCL microspheres. Drug loading and releasing study demonstrated that PEG-PCL concentration could control the encapsulation efficiency and releasing activity of More >

    Kawasaki disease: Medical therapies

    Jane W. Newburger

    Congenital Heart Disease, Vol.12, No.5, pp. 641-643, 2017, DOI:10.1111/chd.12502

    Abstract Medical therapies in patients with Kawasaki disease (KD) are administered to reduce the prevalence of coronary aneurysms, reduce systemic inflammation, and prevent coronary thrombosis. All patients with acute KD should be treated with intravenous immunoglobulin (IVIG) 2 g/kg, generally administered over 10–12 hours. Aspirin has never been shown to prevent aneurysms, but is given for its anti-inflammatory and antipyretic effects until the patient has been afebrile for 2 days, then lowered to an antiplatelet dose. Adjunctive therapy with a longer course of corticosteroids, together with IVIG and aspirin, may be considered for primary treatment in More >
