20090173237 | BREWING APPARATUS FOR PREPARING FOAM, FROTH OR CREMA UNDER LOW PRESSURE - The present invention pertains to a brewing filter apparatus capable of preparing foam, froth, or crema, particularly for coffee beverages, under low pressure. The apparatus can operate at pressures below 15 bar and as low as 1-3 bar. The apparatus comprises a mesh cover, coarse filter, fine filter, large 0-ring, coffee container, small 0-ring, and foam maker having two opposing holes. The holes have a diameter in the range of 0.3 to 1 mm. The crema is created by the turbulent contacting of two opposing jets of coffee, which enter the foam maker through the two opposing holes. To further increase agitation and the surface area for contact, a stainless steel wire mesh may be situated in the center of the foam maker directly in the path of and in between the opposing jets of coffee to facilitate the formation of more crema. | 07-09-2009 |

20090010948 | ANTI-TUMOR VACCINES DELIVERED BY DENDRITIC CELLS DEVOID OF INTERLEUKIN-10 - It has been discovered that reducing, inhibiting or preventing the expression of immunosuppressive cytokines or tolergenic agents in antigen presenting cells improves the ability of the antigen presenting cell to promote an immune response. One embodiment provides a genetically engineered antigen presenting cell that has reduced or no expression of IL-10. Preferred antigen presenting cells are dendritic cells. Expression of IL-10 can be inhibited or blocked by genetically engineering the antigen presenting cell to express inhibitory nucleic acids that inhibit or prevent the expression mRNA encoding immunosuppressive cytokines. Inhibitory nucleic acids include siRNA, antisense RNA, antisense DNA, microRNA, and enzymatic nucleic acids that target mRNA encoding immunosuppressive cytokines. Immunosuppressive cytokines include, but are not limited to IL-10, TGF-β, IL-27, IL-35, or combinations thereof. Tolerogenic agents include but are not limited to indoleamine 2,3-dioxygenase. | 01-08-2009 |
