Abstract:
The disclosed embodiments of the inventions disclosed in this application develop a "protection" electric, magnetic or electromagnetic field or fields which are either superimposed upon an ambient field which is detrimental to the health of living systems, or is incorporated into the electrical circuit of the device which is generating the detrimental field. Either arrangement is successful in "confusing" living cells, and thereby reducing the harmful effects of the otherwise detrimental field.
Abstract:
An arrangement for inhibiting the adverse effect of an ambient time varying field having an electric component of 5 Kv/M or less and/or a magnetic component of 500 mu T or less on a living system. To provide protection, at least one of the characteristic parameters of said field to which the living system is exposed is changed within time intervals of less than 10 seconds.
Abstract:
Methods and apparatus for inhibiting the adverse effect of an ambient time varying field having an electric component and/or a magnetic component on a living system. To provide protection, the field to which the system is exposed is caused to be one wherein at least one of the characteristic parameters of said field to which the living system is exposed is changed within time intervals of less than 10 seconds. The strength of the field to which the living system is to be exposed is controlled as a function of the strength of the ambient field. Living systems which are benefitted include humans.

Abstract:
A method of locating infarcted myocardial tissue in a beating heart includes the step of inserting an impedance measuring tip (10) of a catheter (14) into the chamber of the beating heart and measuring the impedance of the endocardium at various locations within the beating heart. The values measured are compared to impedance values with a predetermined range of values (22) to identify an infarcted area of myocardium and distinguish such area from normal myocardium (20). The measurements are also compared to a range of values for an infarction border zone. The infarction border zone is a significant source of arrhythmia, and particularly of ventricular tachycardia. In accordance with the methods of the present invention, the risk of arrhythmia in a beating heart may be substantially reduced or eliminated by ablating endocardium within the infarction border zone utilizing the same catheter tip.

Abstract:
A method is disclosed for fabricating bulk superconducting materials into shaped articles, including ones of relatively large sizes and complex shapes, which have high densities, high integrity, high magnetization and critical current densities. A mixture of superconducting material is completely or substantially melted and the molten material is then cooled to room temperature and ground to a powder. The ground powder is next mixed with a second phase made up of either precursor superconducting powder or a mixture of metallic silver and copper. The resulting mixture is then shaped into an article by conventional ceramic article forming techniques: pressing, extruding, molding or the like. The resulting shaped article is heated to a temperature at which a substantial amount of its content of second phase material is melted, thus facilitating densification of the entire shaped article. The resulting dense specimen is annealed in an appropriate environment while it is being cooled to room temperature.

Abstract:
Anti-malarial compositions for prophylactic or therapeutic treatment of vertebrates exposed to malaria parasites are disclosed. These compositions comprise one or more pyrimidine analogue inhibitors of nucleic acid biosynthesis, e.g., 5-fluoro-orotic acid, alone or together with one or more ''rescue'' compounds, e.g., a normal pyrimidine base or nucleoside that can be used by the host vertebrate, but not by malaria-causing parasites, for nucleic acid biosynthesis. Also claimed are methods of prophylactic and therapeutic use of these compositions.
