Abstract: Legislations set constraints for free lotteries and other free games of chance. New services which can be charged to players are disclosed as a method, a system, and as the new business model that they create for games of chance and particularly free games of chance.

Abstract: The method consists in a new way of distributing advantages based on a new category of online game.

Abstract: The present invention relates to the field of probiotics. More particularly, the invention pertains to the use of a particular strain, Lactobacillus casei CNCM I-1518, which is present in Actimel®, for alleviating the symptoms of a delayed-type hypersensitivity reaction.

Abstract: An isolated DNA encoding the enzyme I-SceI is provided. The DNA sequence can be incorporated in cloning and expression vectors, transformed cell lines and transgenic animals. The vectors are useful in gene mapping and site-directed insertion of genes.

Abstract: A retroviral vector that eliminates cis-acting retroviral elements, which are not useful to and may cause problems for, an integrated provirus utilizes a recombination system, such as the bacteriophage P1 cre-lox recombination system. A gene of interest and a loxP site are inserted into a long terminal repeat, which is then duplicated. The enzyme cre is inserted between the long terminal repeats and combines them. The structure of the resulting provirus in the host genome is that of a single, long terminal repeat carrying a single copy of the gene of interest. Following infection, the retrovirus produces proviral structures having only a single long terminal repeat.

Abstract: The present invention is concerned with modified polynucleotides derived from a native gene and having a reduced or increased number of epigenetic control motifs, at the nucleotide level, as compared to the native gene. These polynucleotides are useful to study, increase and/or reduce genes expression, and to improve DNA vaccination methods. The present invention also relates to methods of using these modified polynucleotides in in vitro and in vivo expression systems.

Abstract: Process for partial oxidation in a Claus furnace of at least one gas stream having hydrogen sulphide, and including the steps of: (a) injecting at least one gas stream including hydrogen sulphide and at least one oxygen-enriched gas stream into the Claus furnace, wherein each of the streams is injected at a speed of injection which is substantially parallel, and (b) controlling the speed of injection of the gas stream including hydrogen sulphide and the speed of injection of the oxygen-enriched gas stream such that the speeds have a ratio between 0.8 and 1.2.

Abstract: Retroviral vectors contain cis-acting viral elements for the expression, encapsidation, reverse transcription and integration of the retroviral genome nucleic acid sequence. However, these elements are not useful in the integrated provirus and may cause many problems. A retroviral vector is provided for eliminating most of the viral elements. This vector uses, among other things, the bacteriophage P1 Cre-lox recombination system. The 32-nucleotide loxP site is inserted into 3′LTR sequence U3 with the gene to be inserted into the cell. After loxP duplication using the LTR, the LTRs may be recombined by enzyme Cre. The structure of the resulting provirus in the host genome corresponds to a single LTR carrying a single copy of the gene to be inserted into the cell. If the Cre expression unit is inserted between the two LTRS, only single-LTR proviral structures are found following infection with the retroviral vector.
