The importance of seed bank knowledge for the restoration of coastal plant communities - a case study of salt marshes and dune slacks at the Belgian coast [PDF]

open access: yes, 2005
Knowledge on seed bank density and species composition is crucial for predicting the probability that target species will establish in the plant community on a restored site.

Human Brain Vasculature‐on‐a‐Chip Model Constructed With Microvessels Isolated From Cryopreserved Postmortem Human Brain Tissue

open access: yesAdvanced Healthcare Materials, EarlyView.
This manuscript describes the cultivation of viable microvessels from cryopreserved human brain tissue. When embedded in hydrogels and cultured in microfluidic devices, these microvessels exhibit complex architectures reminiscent of arterioles and capillaries, can be perfused, and display intact barrier function. Collectively, these results demonstrate

Estimating soil seed bank characteristics in ponderosa pine forests using vegetation and forest-floor data [PDF]

open access: yes, 2008
Soil seed banks are important for vegetation management because they contain propagules of species that may be considered desirable or undesirable for site colonization after management and disturbance events. Knowledge of seed bank size and composition

A Versatile Engineering Platform for the Fabrication of Prosthetic Venous Valves Using Electrospinning

open access: yesAdvanced Healthcare Materials, EarlyView.
Percutaneous prosthetic venous valves are fabricated by embedding stents in an electrospun matrix that extends luminally to form leaflets. The design shields leaflets from hyperplastic cells, isolates struts from blood contact, and avoids discrete anchoring points.

Seed Bank Variation under Contrasting Site Quality Conditions in Mixed Oak Forests of Southeastern Ohio, USA

open access: yesInternational Journal of Forestry Research, 2010
Seed bank composition was sampled in 192–2.5 m2 quadrats, established in six regenerating clearcut (∼7 years) and six second-growth (∼125 years) mixed-oak forest stands in southeastern Ohio.

A Tri‐Culture Heart‐on‐a‐Chip Platform With iPSC‐Derived Cardiac Cells for Predictive Cardiotoxicity Testing

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents the first entirely isogenic heart‐on‐chip, unifying cardiomyocytes, fibroblasts, and endothelial cells from a single iPSC source. The platform reveals a critical biological insight: the endothelium actively shields cardiac tissue from drug‐induced toxicity, challenging the predictive accuracy of conventional, avascular models for ...

The soil seed bank in abandoned tropical pastures: source of regeneration or invasion?

open access: yesRevista Mexicana de Biodiversidad, 2011
We assessed the availability of both pioneer and non-native species in the soil seed bank of old-growth forest and recently abandoned pasture, to evaluate whether the soil seed bank in these pastures represents a source of regeneration of species from ...

A Cryoprotectant‐Compatible Nanoporous Platform for Stable and Scalable Delivery of Biopharmaceuticals

open access: yesAdvanced Materials, EarlyView.
A cryoprotectant‐compatible nanoporous platform enables ambient‐stable and scalable delivery of gene editing therapeutics. By combining hierarchical pore architecture with optimized lyophilization chemistry, the system preserves Cas9‐RNP activity post‐freeze‐drying.

Factors involved in recruitment process of an endemic gypsophyte species in Spain: Teucrium libanitis

open access: yesRevista Cubana de Ciencias Forestales, 2013
Gypsum soils in arid and semi-arid environments impose an important restriction of vascular plants. Factors controlling the recruitment of gypsophytes species are not completely understood. Recruitment is the combined result of processes involved in soil
