Deferral of routine percutaneous coronary intervention in patients undergoing transcatheter aortic valve implantation: Rationale and design of the PRO-TAVI trial.

Background: Concomitant coronary artery disease (CAD) is highly prevalent in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI). The optimal treatment strategy for CAD is a topic of debate. An initial conservative strategy for CAD in patients undergoing TAVI may be favorable as multiple studies have failed to show an evident beneficial effect of percutaneous coronary intervention (PCI) on mortality after TAVI.

BioRT-HBV 1.0: A Biogeochemical Reactive Transport Model at the Watershed Scale.

Reactive Transport Models (RTMs) are essential tools for understanding and predicting intertwined ecohydrological and biogeochemical processes on land and in rivers. While traditional RTMs have focused primarily on subsurface processes, recent watershed-scale RTMs have integrated ecohydrological and biogeochemical interactions between surface and subsurface. These emergent, watershed-scale RTMs are often spatially explicit and require extensive data, computational power, and computational expertise.

Population genetics of the freshwater red alga Batrachospermum gelatinosum (Rhodophyta) I: Frequent intragametophytic selfing in a monoicous, haploid-diploid species.

Life cycles with a prolonged haploid phase are thought to be correlated with greater rates of selfing and asexual reproduction. In red algae, recent population genetic studies have aimed to test this prediction but have mostly focused on marine species with separate sexes. We characterized the reproductive system of the obligately monoicous (i.
