Abstract: In some embodiments, the present disclosure provides methods for stimulating a subject's immune system. Particular methods provide a tumor specific immune response by injecting a tumor with a magnetorheological fluid and applying a magnetic field to the tumor. The immune response can be used to treat disseminated tumors or metastatic cells. Further methods induce a general immune response, such as by treating a section of tissue, such as healthy tissue, with a magnetorheological fluid and applying a magnetic field to the treated tissue. The immune response can be used to treat illness or disease or to enhance the effect of a therapeutic agent. In particular examples, the disclosed methods are used to enhance the effect of immuno stimulants. Also provided are methods for causing necrosis of a cell mass, such as a tumor, by injecting a magnetorheological fluid into a section of tissue and applying a magnetic field to the tissue.

Abstract: In various embodiments, the present disclosure provides a method, device, and system for generating energy from fluid motion, such as from sea waves. In a specific example, the disclosure provides a device having a submersible housing having an inlet and an outlet. When submerged, the inlet faces toward the direction of fluid propagation such that the fluid is incident on the inlet. The outlet includes a one-way check valve to pass water flowing through the housing from the inlet. The housing further includes a turbine positioned between the inlet and outlet such that water may flow from the inlet, past the turbine, and through the outlet. The turbine is coupled to an electrical generator. In some examples, the fluid has a wavelength ? and the region of the housing between the inlet and outlet has an axial length of ?/2. In further embodiments, the device includes a plurality of inlets and outlets located at different axial positions on the housing.
