  This invention describes a process for hydrogenation of an aromatic feedstock that as a catalytic composition uses a suspension of metal nanoparticles of a mean size of between 1 and 20 nanometers in at least one non-aqueous ionic liquid, whereby said suspension also contains at least one nitrogen-containing ligand, in which said metal nanoparticles comprise a transition metal in the zero-valence state, whereby the transition metal is selected from the groups 8, 9, 10 and 11 of the periodic table and in which said nitrogen-containing ligand comprises 1 to n nitrogen atoms, whereby n is an integer of between 1 and 20.

  这项发明描述了一种对芳香原料进行氢化的过程，其催化组合物使用至少一种非水离子液体中平均尺寸在1至20纳米之间的金属纳米颗粒的悬浮液，该悬浮液还包含至少一种含氮配体，其中所述金属纳米颗粒包括零价态的过渡金属，所述过渡金属选自周期表的8、9、10和11族，并且所述含氮配体包括1到n个氮原子，其中n是介于1和20之间的整数。

  The present invention relates generally to compositions and their use in the treatment and/or prophylaxis of inflammatory conditions in an animal such as a mammal, including a human. More particularly, the compositions of the present invention comprise agents which modulate the level of expression of genes or the level of activity of gene products involved in eliciting an inflammatory response and in particular an asthmatic condition. The present invention also provides methods for identifying additional agents which interact with selected target genes or target gene products, the regulation of which, provide useful means for treating and/or preventing the development of an inflammatory condition such as asthma. Furthermore, methods of treatment and/or prophylaxis in an animal such as a mammal including a human, by the administration of a composition of the present invention, are provided.
