摘要:
Methods of killing or inhibiting tumors comprising of heterogeneous or mixed cell populations is described. The killing or inhibition of tumors is achieved by selectively targeting a unique ligand suspected of being expressed on a particular cell population to also kill a cell population lacking the unique ligand. These conjugates have therapeutic use as they are delivered to a specific cell population to kill these cells and the cytotoxic drug is released to kill non-targeted cells, thereby eliminating the tumor.

摘要:
Methods and devices are disclosed for selective delivery of therapeutic substances to specific histologic or microanatomic areas of organs. Introduction of the therapeutic substance into a hollow organ space (such as an hepatobiliary duct or the gallbladder lumen) at a controlled pressure, volume or rate allows the substance to reach a predetermined cellular layer (such as the ephithelium or sub-epithelial space). The volume or flow rate of the substance can be controlled so that the intralumenal pressure reaches a predetermined threshold level beyond which subsequent subepithelial delivery of the substance occurs. Alternatively, a lower pressure is selected that does not exceed the threshold level, so that delivery occurs substantially only to the epithelial layer. Such site specific delivery of therapeutic agents permits localized delivery of substances (for example to the interstitial tissue of an organ) in concentrations that may otherwise produce systemic toxicity. Occlusion of venous or lymphatic drainage from the organ can also help prevent systemic administration of therapeutic substances, and increase selective delivery to superficial epithelial cellular layers. Delivery of genetic vectors can also be better targeted to cells where gene expression is desired. The access device comprises a cannula with a wall piercing tracar within the lumen. Two axially spaced inflatable balloons engage the wall securing the cannula and sealing the puncture site. A catheter equipped with an occlusion balloon is guided through the cannula to the location where the therapeutic substance is to be delivered.
摘要:
The present invention encompasses a combination of at least one conjugate and one or more chemotherapeutic agent(s) which when administered exerts an unexpectedly enhanced therapeutic effect. The therapeutic effectiveness of the combination is greater than that of the conjugate alone or the administration of one or more of the drug(s) without the conjugate. The present invention is also directed to compositions comprising at least one conjugate and at one or more of chemotherapeutic agent and to methods of treating cancer using at least one conjugate and at least one or more of chemotherapeutic agent (s). The present invention also provides methods of modulating the growth of selected cell populations, such as cancer cells, by administering a therapeutically effective amount of one or more chemotherapeutic agent(s) and at least one conjugate. In each case, such combination has therapeutic synergy or improves the therapeutic index in the treatment of cancer over the anticancer agent(s) alone.

The present invention relates to antibodies that bind CD33. More particularly, the invention relates to anti-CD33 antibodies, fragments and homologues of these antibodies, humanized and resurfaced versions of these antibodies, functional equivalents and improved versions of these antibodies, immunoconjugates and compositions comprising these antibodies, and the uses of same in diagnostic, research and therapeutic applications. The invention also relates to a polynucleotide encoding these antibodies, vectors comprising the polynucleotides, host cells transformed with polynucleotides and methods of producing these antibodies.

摘要:
An LED module latch system for quickly and readily attaching or detaching an LED module to an included mounting panel in an informational display. An LED module having one or more positionable helical spring latches adjacent to the geometry of the mounting panel is secured to the mounting panel by engagement of the helical spring latches. Each helical spring latch includes a pivot pin and a helical spring which are rotatingly positioned to cause intimate rotational engagement of the helical springs with the geometry of the mounting panel.
摘要:
An outdoor electrical display sign with an electrical resistance heating element on a transparent front panel thereof for removing condensation or for dissipating precipitation from the surfaces of the transparent front panel of the sign. The electrical resistance heating element can be adhesively secured onto a surface of the transparent front panel, taped onto a surface of the transparent front panel, laminated between the transparent front panel and an additional transparent polymer panel, photoscreened onto a surface of the transparent front panel, photo-etched onto a surface of the transparent front panel, or formed by pouring electrical resistance material into minute grooves formed in the transparent front panel. The electrical resistance heating element can be on either the inner surface or the outer surface of the transparent front panel, preferably the inner surface.
