摘要:
Novel radiopaque materials comprise heavy metal salts, such as bismuth and uranium salts complexed with a polymer. The metallic complexes which are permanent, nonleachable and have radiopacities at least equivalent to that of aluminum do not adversely affect the mechanical and physical properties of compositions. They are useful as medical and dental resins, in fabricating medical and dental appliances, prosthetic devices, radiation shielding devices and radiopaque polyester fabrics for clothing.
摘要:
Radiopaque polymeric materials comprising halogenated barium salts, homogeneously distributed at the molecular level, provide permanent, nonleachable radiopacities at least equivalent to pure aluminum without adversely affecting mechanical or physical properties of compositions in which they are employed.
摘要:
The present invention relates to the mutant bacteria comprising high levels of folate and being resistant to methotrexate. Also provided are food and food supplement compositions comprising these bacteria and methods for isolating mutant bacteria.
摘要:
The invention relates to the field of food, feed and food supplements comprising high folate levels, whereby the folate is produced by fermentation of Lactobacillus strains on melon fruit extract. Methods for increasing folate production of Lactobacillus strains are also provided.
摘要:
Novel radiopaque materials and a method for their preparation are described. The radiopaque materials comprise composites of polymers and heavy metal-containing organic compounds, which heavy metal containing compounds have the following formula: ##STR1## wherein X is a heavy metThis invention was made with Government support under research Grant No. NIH-1-RO1-DEO6179001A1 awarded by the National Institutes of Health. The Government has certain rights in this invention.
摘要:
Disclosed herein are novel polyorganosiloxanes, both linear and cyclic, havingpendant thereon isocyanate groups derived from specific .alpha.,.alpha.-dimethyl isopropenyl benzyl isocyanates. Also disclosed is a method for production of said polyorganosiloxanes.The disclosed polyorganosiloxanes are useful as crosslinking agents and as intermediates in the production of star polymers, starburst dendrimers, urethanes and ureas.
摘要:
The present invention relates to a method for preparing a soy-based fermented food product using L. delbrueckii and a strain capable of stimulating growth of L. delbrueckii, and a food product obtainable by such method. The invention also provides for a culture comprising said strains, and the use thereof for preparing said fermented food product.
