Introducción y objetivos: Ligustrum sinense (ligustrina) es una reconocida especie exótica invasora. El objetivo de este trabajo fue estudiar los rasgos fisiológicos anatómicos foliares renovales ligustrina que podrían otorgarle ventajas para su establecimiento en un ambiente sotobosque la selva Yungas. M&M: Este estudio se realizó el Parque Nacional Aconquija (Tucumán, Argentina). Se evalu...

In this study, Ligustrum lucidum flowers as raw material, the extraction, isolation and coagulatory activity of polysaccharides were carried out for the first time. The crude polysaccharide was obtained by hot water extraction and ethanol precipitation, and preliminarily purified by Sevage method and D101 macroporous resin. Then the polysaccharide was further purified by DEAE-52 cellulose and S...

An adequate general drought tolerance and the ability to acclimate to changing hydraulic conditions are important features for long-lived woody plants. In this study, we compared hydraulic safety (water potential at 50% loss of conductivity, Psi(50)), hydraulic efficiency (specific conductivity, k(s)), xylem anatomy (mean tracheid diameter, d(mean), mean hydraulic diameter, d(h), conduit wall t...

Birds play crucial role on the pollination of many plants. However, little is known about the interactions between nectarivorous neotropical birds and exotic Angiosperms. S. nilotica is an exotic African plant widely used in Brazilian urban landscaping. However, it has been poorly studied in relation to its interactions with Neotropical birds. In this way, we studied the feeding nectar strategi...

The COSMIC-FFP is a standard method that has been proven effective for measuring the functional size of business applications and realtime software systems from their functional user requirements specification. Despite of this, the methods based on COSMIC-FFP usually require a mapping between the concepts in the requirements specification and their own terms and do not take into account non-fun...

BACKGROUND Accumulating evidence suggests that Fructus Ligustri Lucidi (FLL) plays a beneficial role in preventing the development of osteoporosis. However, the effects of FLL on estrogen receptor (ER) α and ERβ expressions remain unknown. Therefore, in the current study we attempted to probe into the effects of FLL on ERα and ERβ expressions in femurs, tibias and uteri of ovariectomized (OVX) ...
