In vitro model assesses the susceptibility of polymeric scaffolds for material-driven heart valve regeneration to calcificationNARA Subscribed
Purpose Material driven in situ heart valve tissue engineering (HVTE) prospects an alternative to non-living replacements. HVTE exploits bioresorbable (synthetic) scaffolds that guide neo-tissue formation. Proper scaffold design assesses and mitigates potential material-related risks, such as calcific nodule formation. Herein, we establish an in vitro model to investigate the calcification risk of materials for HVTE. Methods C...
Human land use is fragmenting habitats worldwide and inhibiting dispersal among previously connected populations of organisms, often leading to inbreeding depression and reduced evolutionary potential in the face of rapid environmental change. To combat this augmentation of isolated populations with immigrants is sometimes used to facilitate demographic and genetic rescue. Augmentation with immigrants that are genetically and...
Gene flow between phenotypically divergent populations can disrupt local adaptation or, alternatively, may stimulate adaptive evolution by increasing genetic variation. We capitalised on historical Trinidadian guppy transplant experiments to test the phenotypic effects of increased gene flow caused by replicated introductions of adaptively divergent guppies, which were translocated from high‐ to low‐predation environments. We...
