摘要:
The present invention provides variants of C-type natriuretic peptide (CNP) comprising one or more deletions; additions of and/or substitutions with natural amino acids, unnatural amino acids and/or peptidomimetics (including peptide bond isosteres); amino acid extensions; and/or other chemical moieties such as, e.g., poly(ethylene glycol) and hydrophobic acids. The CNP variants are useful as therapeutic agents for the treatment of diseases responsive to CNP, including but not limited to bone-related disorders such as, e.g., skeletal dysplasias and achondroplasia, and vascular smooth muscle disorders such as, e.g., restenosis and arteriosclerosis.

The present invention provides a highly purified recombinant human precursor N-acetylgalactosamine-4-sulfatase and biologically active mutants, fragments and analogs thereof as well as pharmaceutical formulations comprising highly purified recombinant human precursor N-acetylgalactosamine-4-sulfatase. The invention also provides methods for treating diseases caused all or in part by deficiencies in human N-acetylgalactosamine-4-sulfatase including MPS VI and methods for producing and purifying the recombinant precursor enzyme to a highly purified form.
摘要:
The present invention relates to novel variant EGIII or EGIII-like cellulases which have improved stability. The variant cellulases have performance sensitive residues replaced to a residue having improved stability.
摘要:
A packaging system is disclosed which includes a susceptor heating means having selective responsiveness to microwave radiation. The susceptor surface has a plurality of regions, where at least one region has an altered responsiveness to microwave radiation which is achieved by disruptions in the susceptor surface. A method for making regions of a susceptor selectively responsive to microwave heating by disrupting the continuity of the metallized film of the susceptor is also disclosed.

摘要:
A method and apparatus for measuring strong microwave electric field strengths is disclosed. The apparatus includes a first active temperature probe in cooperation with susceptor means for measuring a temperature indicative of the heating effects of microwave radiation at a test location, and an ambient temperature probe for measuring ambient temperature. The temperature differential between the two probes is used by calibration means for determining electric field strength at the test location. The method includes the steps of heating a susceptor means with microwave radiation, and measuring a temperature indicative of the heating effects of microwave radiation at the test location. Ambient temperature is measured, and the temperature differential used to determine the magnitude of the electric field strength.
摘要:
The present invention provides a recombinant human &agr;-L-iduronidase and biologically active fragments and mutants thereof, large scale methods to produce and purify commercial grade recombinant human &agr;-L-iduronidase enzyme as well as methods to treat certain genetic disorders including &agr;-L-iduronidase deficiency and mucopolysaccharidosis I (MPS 1).
摘要:
A method and apparatus is disclosed for a system for heating food products in a variety of microwave ovens. The invention allows the temperature profile of the food product to be set at a predetermined level. A grid is used in combination with a conductive ring. There is preferably a spacing between the grid and the surface of the food product between about 0.25 inch and about 2.4 inches, a margin between openings in the grid between about 0.6 inch and about 1.8 inches, and the openings in the grid are of a size between about 0.75 inch and about 1.75 inches. A single iris embodiment is disclosed. The single iris may be in contact with the surface of the food product or spaced therefrom. An embodiment is also disclosed wherein a grid is in contact with the food surface.
摘要:
There is provided an improved process for the biosynthetic production of indigo, the improvement comprising removing unwanted by-products such as isatin or indirubin from the broth in which such indigo is produced. Isatin can be removed by enzymatic activity using an isatin-removing enzyme such as an isatin hydrolase, or by other techniques such as process parameters (elevated temperature, pH), or by contacting the broth containing the isatin with appropriate adsorption compounds/compositions such as carbon or appropriate resins. Since isatin is the precursor of indirubin, the indirubin levels are decreased as a result of isatin removal.
