  • Patent number: 5143588
    Abstract: A method is provided for enhancing the transport of a selected ion having a predetermined charge-to-mass ratio through a biomolecular membrane located in a space subjected to a local magnetic field. The space defines at least one reference path passing through the membrane in opposite first and second directions. The method includes the steps of creating a magnetic field which, when combined with the local magnetic field, produces a magnetic field having a flux density with at least one component representable by a component vector having a direction extending in the first direction along the path. This component of the magnetic field has a magnitude that fluctuates at a predetermined rate to produce a nonzero average value. A predetermined relationship between the ratio of the selected rate to the nonzero average value and the charge-to-mass ratio of the predetermined ion is thereby created. The predetermined relationship is a function of the cyclotron resonance frequency of the ion.

  • Patent number: 5141627
    Abstract: The present invention relates to a group of organic chelators whose affinity for calcium ion in solution is increased by electromagnetic radiation. Specifically, the chelators are related to BAPTA and utilize the addition of an electron-withdrawing group (e.g., diazocarbonyl) to a ring of BAPTA, para to the amino group. Photochemical rearrangement of the diazoacetyl group converts the group to the electron-donating carboxymethyl group, causing the calcium ion efficiency to increase 25 to 50 fold. These chelators when incorporated into rat fibroblasts either by microinjection or by incubation as the membrane-permeable, enzymatically-labile tetraacetoxymethyl ester and flash-photolyzed cause a drop in intracellular free calcine ion to or below resting valves of about 10.sup.-7 M. These chelators are used to generate controlled fast removal of intracellular free calcium ion to mimic or modulate a number of important cellular responses, especially in nerve or muscle.

  • Patent number: 5131992
    Abstract: A method of heating reactant materials in a plasma chamber to achieve a reaction temperature by enveloping the materials in a microwave induced electric plasma. The plasma chamber positioned in the microwave waveguide is filled with a gas and predetermined quantities of the reactant materials are placed in the chamber or reactor. A microwave produced electric field is passed through the gas to ionize it and produce an electric plasma that envelopes the reactant materials. The process may be used in a variety of high temperature chemical processes such as the production of tungsten carbide.
