摘要:
A method, system, and computer program product for identifying at least one three-dimensionally extended lesion within a volumetric region encompassing an inner surface, an outer surface, and intervening tissue of a target organ. The method includes: (1) generating a set of voxels representing a total scanned volume from a set of cross-sectional images of the target organ; (2) performing segmentation to extract a set of voxels representing the volumetric region from the set of voxels representing the total scanned volume; (3) detecting a set of candidate lesions based on geometric feature values of each voxel in the set of voxels representing the volumetric region; and (4) selecting the at least one three-dimensionally extended lesion from the set of candidate lesions based on at least one of volumetric, morphologic, and texture feature values of each lesion in the set of candidate lesions.
摘要:
Hyperacidified tumors having high .beta.-glucuronidase activity can be treated with glucuronides with aglycones toxic to the tumor cells with great safety toward the rest of the body by first administering an alkalinizing agent in an amount sufficient to maintain the pH level of non-tumor tissues at approximately 7.4 during the glucuronide treatment. This will cause inactivation of .beta.-glucuronidase activity in the rest of the body. Novel glucuronides are disclosed the aglycones of which exert a higher toxic effect in an acid environment or is water-soluble only in an alkaline environment. Such compounds have particular utility with the above process. By substituting radioisotopes into the aglycone, diagnosis and in situ radiation therapy may be accomplished. Bacterial cells having .beta.-glucuronidase activity may also be diagnosed and treated in accordance with the present invention. A urine test is disclosed to determine the amount of free glucuronic acid in the urine which is an indication of the presence of a tumor in the body having high .beta.-glucuronidase activity.
摘要:
Resveratrol and/or pterostilbene are added to wines to preserve the wine from oxidation, bacteria and fungi, as well as to deliver resveratrol to an animal. The resveratrol and/or pterostilbene are also added to red wine to preserve the polyphenols present in red wine. The resveratrol and/or pterostilbene can be added to grape must prior to fermentation and/or to fermented wine prior to bottling.

Esters of organic acids are produced by a transesterification reaction by reacting a first ester with an alcohol to form a second ester in the presence of a catalyst comprising a mixture of DCC and DMAP.
摘要:
Trans-9,cis-11-octadecadienoic acid is produced by forming a urea inclusion complex with cis-linoleic acid, treating the complex with a catalytic amount of a base, and recovering the trans-9,cis-11 octadecadienoic acid. Tans-10,cis-12-octadecadienoic acid is produced by iodinating cis-linoleic acid at temperatures of about −5–20° C. A mixture of trans-9,cis-11 octadecadienoic acid and trans-10,cis-12-octadecadienoic acid comprising is produced by iodinating cis-linoleic acid at temperatures ranging from about 50 to about 90° C.

摘要:
The invention provides a system and method for testing a telephone or communications line to determine if the line qualifies for a particular type or class of communications service, for example DSL service. In accordance with one embodiment, a potential customer can download a software program. The program first performs a DSL distance qualification calculation. If the customer' line passes this step, the program determines whether the line coupled between the customer and a central office servicing that customer is electrically qualified for DSL communications. A series of tests to measure signal levels, noise, and other characteristics are performed by a test server, which generally include local loop tests to determine the presence of bridged taps, load coils, and subscriber line concentrators. After the tests are completed, the customer can receive the results, order completion and other instructions.
摘要:
Pure DHA and pure EPA can be obtained from a mixture of EPA and DHA in a solution by forming salts of DHA and EPA which have different solubilities in the solvent, cooling the solution until the salt of EPA is formed, filtering the solution to recover the salt of EPA, and acidifying the EPA salt and the DHA salt to obtain pure EPA and pure DHA.
摘要:
A composition for treating tumors comprising a combination of at least one oxidizing agent and at least one aldehyde or precursor thereof, which aldehyde forms an insoluble thiazoline with cysteine. Optionally a compound which inhibits glutathione-s-transferase is included.
