Extraction of ellagitannins from oak wood of model casks [PDF]

open access: yes, 2015
Eight experimental model casks were constructed using wood from four oak trees and filled with a 12 % ethanol solution for 200 days. The concentration of ellagitannins was subsequently measured in the solutions and in the inner and outer faces of the ...

A polyethylene glycol functionalized hyaluronic acid coating for cardiovascular catheter lubrication [PDF]

open access: yes, 2020
Catheterization is a common medical operation for cardiovascular disease diagnosis and treatment, where low friction is attained through hydrophilic lubricious coatings. But these coatings can cause iatrogenic complications when particles become lose and

Within-tree and between-tree variation of wood density components in cork oak trees in two sites in Portugal [PDF]

open access: yes, 2008
The axial and radial variation of wood density was studied using microdensitometry in cork oaks ( Quercus suber ) in two sites in Portugal. The observations were made in mature trees under cork production and in juvenile trees before the fi rst cork ...

Fluctuating selection and rapid evolution of oaks during recent climatic transitions

open access: yesPLANTS, PEOPLE, PLANET, Volume 6, Issue 1, Page 221-237, January 2024.
The rapidity of evolutionary changes in trees and whether this pace is sufficient to cope with ongoing climatic change are hotly debated issues in ecology today. Climate warming began in the mid‐19th century, after the Little Ice Age (LIA). Monitoring temporal genetic changes during this climatic transition in multicentennial oak populations revealed ...
