摘要:
The invention concerns a process for the alkylation of at least one isoaffin selected from the group formed by isobutane and isopentane by at least one olefin containing 2 to 6 carbon atoms per molecule in the presence of a liquid acid catalyst, the process comprising mixing a feed comprising the olefin to be converted with an effluent comprising a major portion of isoparaffin in a first mixing zone, and forming an emulsion of said catalyst in a hydrocarbon effluent comprising a major portion of isoparaffin in an emulsifying zone, said effluent constituting the continuous phase of the emulsion thus formed, then mixing a major portion of the emulsion of acid in hydrocarbon effluent with a major portion of the diluted feed comprising the olefin in a second mixing zone, followed by carrying out the majority of the reaction in a reaction zone which is supplied by the major portion of said mixture.

摘要:
This invention relates to methods for treating rheumatoid arthritis (RA) by administering one or more agents that specifically target LIR-2, LIR-3 and LIR-7. Results disclosed herein indicate that these three LIRs may participate in regulating the activation of leukocytes that infiltrate synovial tissue. Thus, inflammation in the joints of RA patients can be ameliorated by administering agents that modulate expression or function of LIR-2 and/or LIR-3 and/or LIR-7 to reduce or eliminate the activation of monocytes or macrophages present in inflamed joints, or to reduce their recruitment to the site of inflammation. This can be accomplished by modulating LIR-7, which transmits a stimulatory signal, and/or by modulating LIR-2 and/or LIR-3, which when triggered exert an inhibitory effect, or by concurrently modulating two or all three of these LIRs.
摘要:
A genus of erythropoietin (Epo) receptor agonists having unique structural, biochemical, and physiological characteristics has been discovered and is referred to herein as Erythropoietin Receptor extended Duration Limited Agonist (EREDLA).
摘要:
An electrical circuit material having a conductive layer disposed a substrate, wherein the substrate comprises an organic or inorganic polymer comprising a covalently bound polyhedral silsesquioxane (POSS). The substrate may further comprise an additional dispersed POSS, any other fillers including fibrous webs. Use of covalently bound POSS allows for flame retardancy in compositions having acceptable dielectric constants and dissipation factors.
摘要:
The present invention provides Tek antagonists and methods of inhibiting angiogenesis in a mammal by administering Tek antagonists. The methods are particularly useful in treating diseases or conditions mediated by angiogenesis, such as solid tumors and diseases or conditions characterized by ocular neovascularization.
摘要:
Flt3-ligand can be used to generate large numbers of dendritic cells from hematopoietic progenitor and stem cells. Flt3-ligand can be used to augment immune responses in vivo, and expand dendritic cells ex vivo. Such dendritic cells can then be used to present tumor, viral or other antigens to naive T cells, can be useful as vaccine adjuvants. When flt3-L is used and/or administered in combination with other reactive agents, e.g. CD40 binding proteins, 4-1BBL or antibodies reactive with 4-1BB, CD30 ligand antagonists, RANKL, and/or interferon alpha the combination further enhances immune responses and the effectiveness of vaccine adjuvants.
