Background and Objectives: Biofilms are a community of bacteria on surfaces coated with extracellular polymeric materials, and one strategy to remove biofilms is to use nanoparticles. The aim of this study was to synthesize green zinc oxide (ZnO) nanoparticles and determine its anti-biofilm effects on biofilm gene expression in multidrug-resistant Klebsiella pneumoniae strains. Materials and M...

We studied the seasonal patterns of water use in three woody species co-occurring in a holm oak forest in northeastern Spain. The three species studied, Quercus ilex L., Phillyrea latifolia L. and Arbutus unedo L., constitute more than 99% of the total basal area of the forest. The study period included the dry seasons of 1999 and 2000. Water use was estimated with Granier-type sap flux sensors...

As a part of our studies on the biologically active substances from Spanish plants, we have undertaken an investigation of the chemical constituents of a typical mediterranean species, Phillyrea latifolia L. (Oleaceae). Two secoiridoid glycosides, three phenylpropanoid glycosides, one lignane and two triterpenic acids were isolated from the leaves of this species and identified. The phytochemic...
