Introduction: Tobacco () cv Bright Yellow-2 (BY-2) cell suspension cultures enable the rapid production of complex protein-based biopharmaceuticals but currently achieve low volumetric productivity due to slow biomass formation. The biomass yield can be improved with tailored media, which can be designed either by laborious trial-and-error experiments or systematic, rational design using mechanistic models, linking nutrient consumption and biomass formation.
Methods: Here we developed an iterative experiment-modeling-optimization workflow to gradually refine such a model and its predictions, based on collected data concerning BY-2 cell macronutrient consumption (sucrose, ammonium, nitrate and phosphate) and biomass formation.
Objectives: To investigate the feasibility and safety of percutaneous transluminal angioplasty (PTA) of the iliofemoral arteries (IFA) before transfemoral transcatheter aortic valve implantation (Tf-TAVI) in patients with advanced peripheral artery disease (PAD).
Background: Although Tf-TAVI represents the access of choice, alternative vascular access routes are preferred for patients displaying advanced PAD. PTA of the IFA represents a less invasive option, broadening the spectrum of patients eligible for Tf-TAVI.
Objectives: The aim of this study was to compare outcomes after transcatheter aortic valve replacement (TAVR) with the SAPIEN 3 Ultra (Ultra) and SAPIEN 3 (S3) transcatheter heart valves (THVs).
Background: The latest generation balloon-expandable Ultra THV incorporates new technical features and might improve outcomes following TAVR.
Methods: This registry included all consecutive patients who underwent TAVR with either the Ultra or S3 between January 2014 and January 2020.
