Human and Porcine Marginal Chordal Forces in a Vacuum Based Physiological In Vitro Mitral Valve ModelNARA Subscribed
Introduction This study aimed to quantitatively investigate the role of marginal chordae of the mitral valve during static closure by analyzing the force within these chordae and its potential correlation with the transvalvular pressure. Materials and Methods Porcine (n = 10) and human (n = 4) mitral valves were mounted in a saddle-shaped annulus clamp, while an in vitro system was utilized to replicate a physiological systoli...
Actionable knowledge for agroecological transformation: a critical realist analysis of co-innovation in a transdisciplinary projectNARA Subscribed
Transdisciplinarity and the production of actionable knowledge with and for societal actors is a central feature of sustainability science. Yet questions remain about whether such efforts genuinely challenge the structural roots of unsustainability or inadvertently reinforce them in pursuit of proximate impacts. This paper responds to calls for more critical monitoring and evaluation by evaluating a transdisciplinary Horizon E...
Native freshwater mussels are declining globally, thus, determining factors associated with bivalve distribution and abundance is critical for native mussel conservation. In the Columbia River Basin, Gonidea angulata (western ridged mussel) is highly threatened, while Margaritifera falcata (western pearlshell) and the invasive clam Corbicula fluminea (Asian clam) are more common. We conducted 147 snorkel surveys, collected env...
An Integrated Biostratigraphy and Chemostratigraphy for the Dawn of the Jurassic (the Hettangian Stage in the Cheshire Basin, UK)NARA Subscribed
Highly resolved Earth System reconstructions of the Earliest Jurassic are hampered by complexities of existing reference sections. Here, an integrated stratigraphy of two core records is constructed, representing the expanded Hettangian sequence of the Cheshire Basin, UK. The combined record is based on ammonite and calcareous nannofossil biostratigraphy, organic carbon isotope ratios, and bulk rock chemical properties of lega...
