A contribution to the knowledge of Bactrocera oleae (GMEL) in Tras-os-Montes region (northeastern Portugal): phenology, losses and control
Severe damage is caused by the olive fly (Bactrocera oleae (Gmel)) in the Trás-osMontes
region. In order to develop a control strategy, two olive groves for oil production
("Cobrançosa" and "Verdeal") and one for table olive ("Negrinha de Freixo") were
assessed ( 1993-1996). The insect phenology, yield losses and fruit infestation were
evaluated.
The insect's peak flight period occurred during the first half of October. Severe yield
losses due to the pest occurred in 1995, reaching 19 % of the total harvest. It is concluded
that earlier harvesting (second half of September) can avoid substantial losses because the
main period of infestation in all years occurred in October

Hyaluronic acid/poly-L-lysine bilayered silica nanoparticles enhance the osteogenic differentiation of human mesenchymal stem cells
First published online 15 Aug 2014Herein, we evaluate the influence of a PLL–HA bilayer on the surface of silica nanoparticles on their capacity to induce the osteogenic differentiation of human bone marrow stem cells (hBMSCs), as a function of their concentration (50 μg mL−1, 25 μg mL−1 and 12.5 μg mL−1). To this purpose, we synthesized silica nanoparticles (diameter of 250 nm; ζ-potential of −25 mV) that were coated with PLL–HA (diameter of 560 nm; ζ-potential of −35 mV). The cell viability, cell proliferation, protein quantification (i.e. MTS, DNA and ALP, respectively) and gene expression (of osteogenesis-related genes: ALP, osteocalcin, collagen type I, bone sialoprotein, Runx-2, osteopontin and osterix) were monitored, for 21 days. We observed the overexpression of most of the tested osteogenic transcripts in the hBMSCs cultured with SiO2–PLL–HA, at concentrations of 25 μg mL−1 and 12.5 μg mL−1. These results indicate that the proposed nanoparticles temporarily improve the osteogenic differentiation of hBMSCs at low nanoparticle concentrations.We acknowledge funding from the European Union Seventh Framework Programme (FP7/2007-2013) under grant agreement number REGPOT-CT2012-316331-POLARIS.
