https://www.selleckchem.com/products/ABT-263.html A percutaneous pulmonary valve-in-valve (PPVIV) implantation in small surgical tissue valves may be limited due to the valve's initial diameter. Fracturing of the valve's integrity by high-pressure balloons may enhance the diameter and facilitate subsequent PPVIV with a large valve. To the best of our knowledge, the Trifecta® valve seemed not to be accessible for fracturing. We report a case of successful 19-mm Trifecta valve fracturing, followed by PPVIV using a 26-mm Edwards SAPIEN 3 valve in pulmonary position. By repetitively using a high-pressure balloon 5 mm larger than the labeled valve size, we were able to fracture the valve's integrity and implant a 26-mm valve thereafter. Therefore, Trifecta valve appears to be suitable for valve ring fracturing and subsequent PPVIV in certain patients. © 2020 The Authors. Catheterization and Cardiovascular Interventions published by Wiley Periodicals, Inc.Selectively capturing toxic oxoanions of selenium and arsenic is highly desired for the remediation of hazardous waste. Ionic metal-organic frameworks (iMOFs) especially cationic MOFs (iMOF-C) as ion-exchange materials, featuring aqueous phase stability, present a robust pathway for sequestration of the oxoanions owing to their ability to prevent leaching because of their ionic nature. On account of scarcity of water-stable cationic MOFs, the capture of oxoanions of selenium and arsenic has been a major challenge and has not been investigated using iMOFs. Herein, we demonstrate large scale synthesis of cationic MOF, viz. iMOF-1C that exhibits selective capture of oxoanions of SeVI (SeO4 2- ) and AsV (HAsO4 2- ) in water with a maximum sorption capacity of 100 and 85 mg g-1 , respectively. This represents among the highest uptake capacities observed for selenate oxoanion in MOFs. Further, the ion-exchange mechanism was directly unveiled by single crystal analysis, which revealed variable modes of host-guest binding. © 202
