摘要:We aimed to investigate the safety and medium-term durability of an adjustable mitral annuloplasty ring in patients undergoing surgery for mitral valve regurgitation. Forty-five patients requiring mitral valve repair were enrolled into this prospective, multicentre study bet...

摘要:Abstract(#br)Unsupervised learning of a generalizable model of the visual appearance of humans from video data is of major importance for computing systems interacting naturally with their users and others. We propose a step towards automatic behavior understanding by making the ...

摘要:Abstract(#br)2,4-dihydroxybutyrate (DHB) is a precursor for the chemical synthesis of the methionine analogue 2-hydroxy-4-(methylthio)butyrate. Since no annotated metabolic pathway exists for its microbial production from sugar, we have conceived a two-step synthetic metabolic pa...

摘要:Abstract(#br)The heptapeptide angiotensin (Ang)-(1–7) is part of the beneficial arm of the renin-angiotensin system. Ang-(1–7) has cardiovascular protective effects, stimulates regeneration, and opposes the often detrimental effects of AngII. We recently identified the G pro...

摘要:Abstract(#br)Objectives(#br)This study sought to compare 2 next-generation transcatheter heart valves (THV), the self-expanding ACURATE neo (NEO) and the balloon-expandable SAPIEN 3 (S3), in terms of device failure and early safety at 30 days.(#br)Background(#br)Deployment o...

摘要:Abstract(#br)The Mas receptor is involved in the angiotensin (Ang)-(1–7) vasodilatory actions by increasing nitric oxide production (NO). We have previously demonstrated an increased production of Ang-(1–7) in human umbilical vein endothelial cells (HUVEC) exposed to estradi...

摘要:Abstract(#br)Intraoperative surgical prosthetic heart valve (SHV) choice is a key determinant of successful surgery and positive postoperative outcomes. Currently, many controversies exist around the sizing and labeling of SHVs rendering the comparison of different valves di...

摘要:Abstract(#br)The energy-intensive dewatering of algae biomass, the first step of most downstream processes, remains one of the big challenges for economically relevant photoautotrophic bioprocesses. Due to its scalability and easy construction, froth flotation using the inte...

摘要:Abstract(#br)The application of standard sensor electrodes is often limited to stirred tank reactors due to their wired nature and their large space requirement. For other cultivation systems, sensors require a great technical effort to be implemented. Here we propose a new conce...
