Abstract: The invention consists of recombinant gene expression vectors and vaccines useful in immunization of a host against an antigen and methods for use of such vectors and vaccines. In particular, the recombinant gene expression vectors of the invention are plasmids, cosmids or viruses which include non-coding, palindromic regions of single or double-stranded DNA or RNA polynucleotides which include at least one cytosine-guanine dinucleotide motif in each palindrome. These polynucleotide regions of each expression vector are immunostimulatory and serve as adjuvants to vaccination protocols against target antigens. Most preferably, the recombinant gene expression vectors of the invention are naked; i.e., non-viral vectors not associated with a delivery vehicle such as a liposome. The invention also includes live viral vaccines wherein the viruses include immunostimulatory polynucleotides of the invention. According to a preferred method of the invention, a target protein antigen is administered through its expression by a recombinant gene expression vector which contains the non-coding, immunostimulatory polynucleotides of the invention. In the most preferred embodiment of the method of the invention, the recombinant gene expression vector is administered to tissues of the host which contain a relatively high concentration of antigen presenting cells (e.g., skin or mucosa) compared to other host tissues.

L'appareil comprend une pluralité de chambres de traitement flexibles ou semi-flexibles comportant une ou plusieurs poches de culture individuelles, une pluralité de plaques d'espacement rigides, un manifold de fluide d'entrée, un manifold de fluide de sortie, un réservoir à fluide et un organe de transport du fluide à l'intérieur du système. Au cours du traitement, un milieu liquide est transporté du réservoir à fluide vers le manifold d'entrée qui répartit, tour à tour et uniformément, le fluide vers chacune des chambres de traitement reliées et donc vers les poches de culture internes. On a également prévu un manifold de fluide de sortie qui assure d'une part, le remplissage uniforme de chaque chambre de traitement et d'autre part la suppression de toute bulle d'air formée dans les chambres de traitement au cours du traitement. Lesdites chambres de traitement sont flexibles ou semi-flexibles de façon à assurer à l'utilisateur final une manipulation aisée pendant le rinçage et la pose des greffons de culture. En raison de la flexibilité des chambres de traitement, on dispose également des éléments d'espacement rigides qui assurent une répartition uniforme du fluide à l'intérieur des chambres pendant le traitement.

Abstract: involves pressurising wood and injecting water vapour before pressure reduction and dehumidifying. The wood drying method includes the following stages: - a pressure stage in which a set pressure is maintained in a sealed enclosure (1) by injection of a saturated water vapour and maintenance of the pressure for a set period of time, and ensuring forced air circulation with saturated water vapour; - a heating stage at the heart of the wood and in the central zone of the pieces of wood to be dried, by transmission of micro-waves in a frequency range from 400 to 2450 MHz; - an evacuation stage for the water running into the bottom of the enclosure (1), followed by a progressive reduction of the pressure to atmospheric pressure after the micro-wave radiation has stopped. The pressure reduction stage is completed by a dehumidifying of the ambient air in the enclosure, by passage of an air flow from the enclosure onto a humidity absorbing and air cooling system.
