The objective was to evaluate the stability of nanoparticles prepared with poly(epsilon-caprolactone), poly(D,L-lactide) and poly(D,L-lactide-co-glycolide) polymers and stored at different temperatures and in different media. The stability parameters studied were molecular weight and crystallinity of the polymer, nanoparticle size and pH. The results show(More)
The objective of this work was to develop a new delivery system which could enhance the mucosal immune response to influenza virus antigens. Poly(D,L-lactide-co-glycolide) nanoparticles of about 200 nm containing hemagglutinin were chosen as the delivery system. Due to the amphiphilic nature of hemagglutinin (hydrophilic HA1 and hydrophobic HA2),(More)
The aim of this study was to evaluate the potential of poly(D,L-lactide-co-glycolide) nano-and microspheres, with a mean diameter of 220 nm and 8 microm, respectively, to enhance the nasal and systemic immune responses against influenza virus antigen. High encapsulation levels of antigen were achieved in all cases. Neither the molecular weight nor the(More)
The knowledge of patient neuro-anatomy is key information, at least in the understanding of the pathological processes and in the elaboration of precise treatment strategies in neurosurgery. In addition to classical radiology systems like angiography, CT scanner or MRI have greatly contributed to the improvement of the patient anatomy investigation. Each(More)
Conventional wisdom holds that the efficient way to achieve a climate target is to price carbon emissions at a rate that increases exponentially. We show that an exponentially increasing tax on carbon emissions is not efficient when climate targets are expressed in terms of temperature. In that case, the least-cost policy path deviates from an exponential(More)
