Abstract Despite the remarkable progress in the characterization of the molecular pathogenesis of glioblastoma multiforme (GBM), these tumors remain incurable and, in most cases, refractory to aggressive cytotoxic treatments. We conducted a morphological and cytogenetic study in two GBM cell lines (U343 and AHOL1), before and after treatment with pisosterol (at 0.5, 1.0 and 1.8 µg ml −1 ), a triterpene isolated from the fungus Pisolithus tinctorius . No significant alteration was observed in the morphology ...

Lipid-based nanoparticle systems have been used as vehicles for chemotherapeutic agents in experimental cancer treatments. Those systems have generally been credited with attenuating the severe toxicity of chemotherapeutic agents. This study aimed to investigate the effects of associating paclitaxel (PTX) with a lipid-based nanoparticle system on a nonhuman primate, Cebus apella, documenting the toxicity as measured by serum biochemistry, which is a detailed analysis of blood and tissue.

Bursaphelenchus xylophilus (Steiner & Buhrer, 1934) Nickle, 1970 is the causal agent of pine wilt disease (PWD) in Pinus. It is a quarantine organism in the European Union (Directive 77/93, EEC) and an impediment to international trade of forest products. A pest risk analysis for B. xylophilus and its vectors in the genus Monochamus for the territories of the European Union concluded that, due to the frequent occurrence of susceptible pine hosts in Europe and the presence of suitable insect vectors, ...

The polyquaternium 7® polymer is widely used in cosmetic formulations. Morphologic alterations in hair fibers were observed after the application of the polyquaternium 7® polymer, using SEM and AFM. Continuous applications of this product indicated that it accumulates on the fibers, improving the aspect of the hair surface. Quantitative analysis of the images obtained by AFM was undertaken. The data obtained for the hair surface roughness indicates that the fibers treated with the polymer presented ...

Both systems show negative deviations from Raoult's law at all temperatures. The corresponding excess molar Gibbs energies ( ) have been calculated from the vapor pressure results. Liquid molar volumes have also been measured for both mixtures at 161.40 K, leading to calculated excess molar volumes ( ) which are negative in all cases. Additionally, the ...

The detection of Bursaphelenchus xylophilus in Pinus pinaster trees in Portugal in 1999 led the official services to implement exceptional and urgent control measures to prevent the spread of the pest. Because the pest is vector‐transmitted, special attention was paid to the insects associated with infested trees. A survey comprising 21 species of insects, from six families, with a total of 1367 specimens, was made in order to evaluate their possible role as vectors of the nematode in Portugal. ...

Background The pinewood nematode (PWN) Bursaphelenchus xylophilus is an important conifer disease worldwide. It is the direct cause of the death of millions of pines in south-east Asia (mainly Japan, China and Korea) and has been established in Portugal since 1999. The phasing out of methyl bromide has created an urgent need for alternative treatment of wood packaging materials. The effect of sulfuryl fluoride (SF), a broad-spectrum fumigant used to control insects, was tested in Pinus pinaster boards ...

We have developed a new chlorophyllic cell line ('TADH-XO') from the highly water stress tolerant grass Bouteloua gracilis (blue grama). When grown under normal (non-stress) conditions, this new cell line accumulates higher levels of chlorophyll (up to 368.1 microg total chlorophyll g(-1) FW) than a previously obtained cell line ('TIANSJ98'). Both cell lines are capable of developing substantially higher amounts of chlorophyll when subjected to osmotic stress. In order to explain these changes in the chlorophyll ...

A correlation between the proportion of infested trees and average temperature was found. Tree diameter and tree phytosanitary variables further contribute to the attack densities of ambrosia beetles. Results can be relevant for preventive measures aiming to conserve this natural forest heritage. Cork oak ...

Xanthan gum solutions were used as rheologically evolving fluids to evaluate changes in mixing time under non-aerated and aerated conditions. The helical ribbon agitator and turbine of the hybrid dual mixing system was kept at a constant rotational speed ratio, NT/NHR= 10. Experiments showed that performance of the hybrid mixing system ...

The rheological properties of aqueous solutions of the mucilage isolated from Opuntia ficus indica have been examined. Steady-shear viscosities in a range of shear rate from 1 to 300 s−1 were observed as a function of mucilage concentration, temperature, pH and ionic strength. A non-Newtonian shear-thinning behavior was observed. A quite important increase in pseudoplasticity (or shear thinning) due to increase in the mucilage concentration, in the range from 1 to 10% (w/w) was showed. In the range ...
