Abstract: The invention provides systems, methods for 14 treatment, and occlusion of the fallopian tube. An elongated catheter (22) is placed into the isthmic region (14) of the fallopian tube (16) in a trans-cervical trans-uterine fashion, and a mono-pole antenna (92) is disposed within a distal end of the catheter. The antenna radiates microwave energy in resonance to a drive frequency into tissue of the isthmic region without physical contact between the mono-pole antenna, and the tissue. This heating causes occlusion after a period of time. Typically, the catheter, and the mono-pole antenna are disposable after one treatment. In the preferred embodiment, the antenna is formed from an extension of the inner conductor of a coaxial cable coupled to a microwave generator. A power control section (24) can be used to control, and apply the appropriate microwave power to the fallopian tube tissue.

Abstract: The invention includes system for modifying ice adhesion strength of ice adhered to an object. The system includes an electrode that is electrically insulated from the object and a DC source, e.g., a battery, coupled to the object and the electrode. The source generates a DC bias to an interface between the ice and the object when the ice completes the circuit. The object is conductive or is doped as a semiconductor so that the DC bias applies a voltage to the interface which modifies the ice adhesion strength selectively as compared to the ice adhesion strength with substantially zero bias voltage at the interface. The strength can be increased or decreased relative to its static state (i.e., the state without applied voltage). In this manner, ice such as ice on an aircraft wing can be removed with less work. The system preferably includes an electrically insulating material disposed between the object and the electrode; the insulating material is substantially conformal to the object and the electrode.
Abstract: A method of augmenting T cell-mediated immunity against Toxoplasma gondii is provided. Immunization with Toxoplasma gondii soluble parasite antigen and exogenous rIL-15 was found to protect against Toxoplasma gondii infection.

Abstract: Methods for inducing T cell tolerance to a tissue or organ graft in a transplant recipeint are disclosed. The methods involve administering to a subject: 1) an allogeneic or xenogeneic cell which expresses donor antigens and which has a ligand on the cell surface which interacts with a receptor on the surface of a recipient T cell which mediates contact-dependent helper effector function; and 2) an antagonist of the receptor which inhibits interaction of the ligand with the receptor. In a preferred embodiment, the allogeneic or xenogeneic cell is a B cell, preferably a resting B cell, and the molecule on the surface of the T cell which mediates contact-dependent helper effector function is gp39. A preferred gp39 antagonist is an anti-gp39 antibody. The allogeneic or xenogeneic cell and the gp39 antagonist are typically administered to a transplant recipient prior to transplantation of the tissue or organ.

Abstract: A method for reducing a risk of carcinogenesis in a subject comprising administering a dose of calcium to the subject that is effective to reduce carcinogenesis. Particularly provided is a method for reducing the risk of recurrence of colorectal adenomas, comprising administering a dose of calcium carbonate effective to reduce the risk of colorectal adenomas. In an example, 1200 mg of elemental calcium (supplied in 3000 mg of calcium carbonate) administered twice daily resulted in decreased risk of recurrent colorectal adenomas in patients with a history of colorectal adenomas.
Abstract: Method for the treatment of multiple sclerosis and other T cell mediated autoimmune disorders is described. The method involves administering to a subject a therapeutically effective amount of an antagonist of a receptor on a surface of a T cell which mediates contact dependent helper effector functions, for example, an anti-gp39 antibody.

Abstract: A system and method is described for determining and graphically displaying oxygenation states of a patient in real time. The system is non-invasive and can display information to a physician that is intuitive. Various display objects are described for illustrating the output of oxygenation values. The display objects reflect the in vivo physiology that they measure, thus making interpretation of the measured values very intuitive.
