Bien que la découverte des doubles émulsions remonte à la fin du siècle dernier, c'est seulement depuis quelques dizaines d'années qu'on observe un regain d'intérêts pour ces émulsions, notamment en galénique moderne. En particulier, les émulsions eau dans huile dans eau (w/o/w) sont utilisées pour produire des microparticules solides en vue d'immobiliser un principe actif hydrosoluble. [less ▲]

Les micro-algues sont des micro-organismes photosynthétiques. Leur croissance en milieu aqueux nécessite un apport lumineux (l = 400 à 700 nm) ainsi qu’un apport en carbone et en nutriments (N, P, S, etc.). Certaines souches, Dunaliella sp. par exemple, sont couramment utilisées dans le cadre de la biosynthèse de caroténoïdes[1] (b-carotène, lutéine entre autres). Quelques recherches ont montré qu’il était possible de réaliser l’extraction in situ des métabolites produits dans un réacteur biphasique (le b-carotène hydrophobe est extrait dans une phase organique biocompatible telle que le décane ou le dodécane) [2,3,4,5]. Le projet FOTOBIOMAT (subsidié par le programme Greenomat de la Région Wallonne – Belgique) a pour but de développer un nouveau type de photobioréacteur dans lequel sont mises en oeuvre les micro-algues encapsulées dans des billes constituées d’un matériau hybride. Le processus de photosynthèse est ainsi utilisé afin de convertir du CO2 en composés à haute valeur ajoutée (b-carotène p. ex.). La viabilité des micro-algues encapsulées doit être très importante (min. 6 mois). Idéalement, le b-carotène produit devrait être récupéré par une voie “propre” et ce, quasi en continu. [less ▲]

Long-term genetic and functional stability is a fundamental requirement for the maintenance of microorganisms. Cryopreservation is the preferred method for the long-term storage of many micro-organisms, including cyanobacteria. The BCCM/ULC collection currently holds over 200 cyanobacterial strains as living cultures, but only 62 are maintained in a cryo-preserved state. The main limiting factors are the low levels of survival of some strains, as well as the long periods required to recover from cryopreservation, and thus the inability to rapidly deliver strains to clients.. The BRAIN-be project PRESPHOTO (preservation of photosynthetic micro-algae in the BCCM collections) (www.presphoto.ulg.ac.be) aims to improve the preservation of cyanobacterial and diatoms in the BCCM/ULC and BCCM/DCG collections, respec-tively. The encapsulation-dehydration is often considered as a promising alternative to the traditional cryopreservation method for recalcitrant microalgal strains. In this technique, cyanobacterial cultures are entrapped in calcium-alginate beads, osmotically dehydrated (traditionally with sucrose solutions), then evaporatively desiccated in a sterile air flow, or over silica gel and subsequently cryopreserved. In this study, the encapsulation-dehydration method was evaluated as potential long-term preservation technique of cyanobacterial strains. The effects of several factors on the viability of 4 strains have been investigated to determine which are the most important for the successful cryopreservation. In particular, several cryoprotectants (i.e. sucrose, PEG or mannitol), methods of beads dehydration (i.e. under a laminar flow or with silica gel) were tested. We have also compared storage at -70°C and in liquid nitrogen (-196oC). A pre-cultivation step in KCl was also tested for its ability to enhance desiccation tolerance. In addition, the use of alginate dissolution buffer following thawing was also considered. In the final phase of the project, the selected cryopreservation protocols will be tested on a large set of strains. In addition, an independent validation of the protocols will be also performed by both partners of the project (BCCM/DCG and the Culture Collection of Algae and Protozoa). [less ▲]

INTRODUCTION: Encephalitis is a rare complication of primary varicella-zoster virus (VZV) infection in immunocompetent children. METHODS: The clinical and laboratory findings of two girls with VZV-related encephalitis are reported. RESULTS: Both children presented with focal epileptic seizures, corresponding to cortical/subcortical as well as white matter lesions. The first showed a typical vesicular skin rash. She was easily diagnosed and made a rapid recovery during acyclovir and steroid treatment. In the second girl, a preceding measles-mumps-rubella virus vaccination and the absence of skin vesicles were misleading with respect to the diagnosis, which was finally proven by IgG seroconversion and intrathecal synthesis of IgG antibodies to VZV. She developed left parieto-occipital tissue necrosis and recovered only transiently during initial acyclovir/steroid treatment. Eight weeks after onset, progressive white matter demyelination and the occurrence of erythema nodosum in the lower limbs necessitated a second 4-month course of oral steroids. The VZV PCR from cerebrospinal fluid was negative in both children. CONCLUSIONS: Primary VZV infection may cause severe encephalitis that may occur without skin vesicles and lead to a chronic course with systemic vasculitis. The coincidence of vaccination and neurologic diseases offers no proof per se of a causal relationship. [less ▲]
