International Classification:

A61K 914

US Classification:

424489, 424490, 424443, 424448, 424445, 424447

Abstract:

A magnetically controllable, or guided, ferrocarbon particle composition and methods of use and production are disclosed. The composition may optionally carry biologically active substances that have been adsorbed onto the particle. The composition comprises composite, volume-compounded particles of 0. 1 to 5. 0 m in size, and preferably between 0. 5 and 5. 0 m, containing 1. 0 to 95. 0% by mass of carbon, and preferably from about 20% to about 60%. The particles may be produced by mechanical milling of a mixture of iron and carbon powders. The obtained particles are optionally placed in a solution of a biologically active substance to adsorb the substance onto the particles. The composition is generally administered in suspension.

Abstract:

A magnetically controllable, or guided, ferrocarbon particle composition and methods of use and production are disclosed. The composition may optionally carry biologically active substances that have been adsorbed onto the particle. The composition comprises composite, volume-compounded particles of 0.1 to 5.0 m in size, and preferably between 0.5 and 5.0 m, containing 1.0 to 95.0% by mass of carbon, and preferably from about 20% to about 60%. The particles may be produced by mechanical milling of a mixture of iron and carbon powders. The obtained particles are optionally placed in a solution of a biologically active substance to adsorb the substance onto the particles. The composition is generally administered in suspension.

International Classification:

G01N 2188

US Classification:

356 72

Abstract:

A method and apparatus for measuring characteristics of a piece of material, typically semiconductor materials including photovoltaic devices. The characteristics may include dislocation defect density, grain boundaries, reflectance, external LBIC, internal LBIC, and minority carrier diffusion length. The apparatus includes a light source, an integrating sphere, and a detector communicating with a computer. The measurement or calculation of the characteristics is calibrated to provide accurate, absolute values. The calibration is performed by substituting a standard sample for the piece of material, the sample having a known quantity of one or more of the relevant characteristics. The quantity measured by the system of the relevant characteristic is compared to the known quantity and a calibration constant is created thereby.

Assignee:

Block/Chemex, G.P. - Jersey City NJ

International Classification:

A61K 3105

US Classification:

514731

Abstract:

The invention relates to methods useful in the treatment of benign, premalignant and malignant solid tumors, especially those of the skin comprising methods for the administration of pharmacologically active compositions containing catecholic butanes. The invention also relates to methods of preventing the occurrence of tumors, and the use of catecholic butanes as a sunscreening agent. The preferred catecholic butane is nordihydroguaiaretic acid. The preferred methods of application of the compositions containing catecholic butanes are by topical application and intratumor injection.
