Title: Cancer immunotherapy using allostimulated cells in a multiple sequential implantation strategy
Inventor: HISERODT JOHN C
IPC: A61K39/00
Filed: 1998-09-29
Granted: 2005-01-25
Abstract: This invention provides medicaments and methods for managing cancer using donor cells that are alloactivated in culture. Alloactivated cells are implanted into the bed of a solid tumor and initiate a response by the host against the tumor. Subsequently, alloactivated cells are implanted into the bed of a solid tumor a second time. The two implants work synergistically to confer remarkable benefit to the treated subject, both in terms of management of the cancer and the development of an anti-cancer immune response. The beneficial effects may include regression of the tumor and extended survival. Removal of any residual tumor after the second implant facilitates ongoing resistance to tumor regrowth or metastasis.

Abstract: A closed cycle thermodynamic apparatus (10) is provided for powering a combustion machine. The apparatus (10) has a compressor (12) for compress-ing a working medium from a reservoir (14) at temperature T1. The temperature of the working medium increases during compression and reaches temperature T2 when leaving the compressor (12). It is then expanded in an expander (16) for turning the machine. In this manner mechanical work is extracted from the working medium. The apparatus (10) has a first heat exchanger (18) and a second heat exchanger (20) connected to the compressor (12) andthe expander (16) in a closed cycle. It also has a bumer (22) and a third heat exchanger (24). Air, as a Heat transfer medium, at ambient temperature T5 is induced into the second exchanger (20) to cool the working medium by receiving heat therefrom. The temperature of the working medium decreases from T4 to T1 before entering the compressor (12) for repeating the cycle. The air which is now at a higher temperature T6 is conveyed to the burner (22) where it is mixed with fuel to form a combustion gas reaching an even higher temperature at T7 and passed into the first exchanger (18) for heating the working medium at constant pressure. In this manner the temperature of working medium increases to T3 when entering the expander (16) and following expansion for conversion to mechanical power its temperature reduces to T4. The apparatus (10) thereby recovers heat at all the heat exchangers (18),(20) and (24). This reduces the amount of fuel required to heat the air for combustion.

Ces chaînes peuvent être formées par polymérisation à une position désirée de façon à présenter une longueur désirée. La tension d'impulsion peut être appliquée à l'aide de la sonde d'un microscope à effet tunnel. Les imperfections formées sur le film mince peuvent être utilisées comme points d'extrémité des chaînes moléculaires polymères de façon à régler la longueur du monomère.

Abstract: L'invention concerne un procédé de préparation d'une résine naturelle par liquéfaction de bois, d'écorce, de résidus forestiers, de résidus de l'industrie du bois, ou d'autres biomasses par distillation destructive rapide (pyrolyse rapide). La pyrolyse rapide produit à la fois des vapeurs et des surfaces carbonisées de la biomasse. Suite à l'élimination des surfaces carbonisées des vapeurs produites, un produit de poix liquide est récupéré et traité par distillation, évaporation, ou une combinaison des deux, afin d'obtenir une résine naturelle pouvant se présenter sous forme liquide ou solide. La résine naturelle comprend un contenu phénolique total d'environ 30 % à environ 80 % (en poids), et constitue un composé de lignine hautement réactif, apte à être utilisé dans des formulations de résine sans nécessité d'avoir recours à d'autres techniques d'extraction ou de fractionnement. Des résines comprenant jusqu'à 60 % de résine naturelle ont été préparées et testées dans la production de panneaux et présentent des propriétés semblables associées à des résines disponibles dans le commerce. La résine naturelle peut remplacer le phénol, ou le phénol et le formaldéhyde dans des résines contenant du phénol. De façon similaire, la résine naturelle peut remplacer une bonne partie des composants dans des résines contenant de l'urée.

Abstract: Using an imaging system, an optical MEMS devices is imaged so that in combination with an actual one or more other optical MEMS devices, or images thereof, a single virtual optical MEMS device is formed that has the size of each of the optical MEMS devices combined. The physical size of the arrangement may be reduced by compacting the optical path, e.g., using appropriate conventional mirrors, and/or employing folded arrangements, i.e., arrangements in which there is only one MEMS device stage that does double duty for both input and output through the use of at least one conventional mirror. The imaging system may reproduce the angle of reflection of the light from the micro mirror, e.g., using a telecentric system. A prism may be employed to align the various optical MEMS devices, or images thereof.
