摘要:
An instrument (10) is provided having a shaft (12) extending to a distal end (16). The distal end (16) has a distal tip member (40) having a cavity (42, 83), and a passageway (44, 80) extending to the cavity through which a first suture end (48A) of a loop of suture (48) extends from a tissue site to facilitate a user looping a second suture end (48B) around the first suture end (48A) between the distal tip member (40) and the tissue site to form a knot (48C). Advancing of the distal tip rrember (40) while drawing the first suture end (48A) through the passageway (44, 80) pushes the knot (48C) for placement at the tissue site.

A material encapsulation and release system having a first zone (1) containing a first amount of material (2) bound by a first capsule wall (3) and, if desired, a second zone (4) containing a second amount of material (5) bound by a second capsule wall (6), each capsule wall responsive to similar or dissimilar activation means (7) to release the first amount of material (2) in the first zone (1) and the second amount of material (5) in the second zone (4).
摘要:
The present invention relates to oral pharmaceutical compositions and methods for improved delivery of therapeutic agents, e.g., lipid-regulating agents. Compositions of the present invention include a carrier, where the carrier contains a combination of a triglyceride and at least two surfactants, at least one of which is hydrophilic. Upon dilution with an aqueous medium, the composition forms a clear, aqueous dispersion. The invention also pertains to methods for treating lipid disorders such as hypercholesterolemia, hypertriglyceridemia, and mixed dyslipidemia by oral administration of the compositions provided.
摘要:
A novel encapsulated product is provided and includes: at least one pharmaceutical; at least one compressible material; and at least one tableting material; wherein the encapsulated product is in the form of a caplet having a diameter of from about 1 millimeter to about 7 millimeters and a length from about 1 millimeter to about 7 millimeters. A method for preparing the encapsulated product is also provided.
摘要:
Poly( beta amino esters)prepared from the conjugate addition of bis(secondary amines) or primary amines to a bis (acylate ester) are described. Methods of preparing these polymers from commercially available starting materials are also provided. These tertiary amine-containing polymers are preferably biodegradable and biocompatible and may be used in a variety of drug delivery systems. Given the poly(amine) nature of these polymers, they are particularly suited for the delivery of polynucleotides. Nanoparticles containing polymer/polynucleotide complexes have been prepared. The inventive polymers may also be used to encapsulate other agents to be delivered. They are particularly useful in delivering labile agents given their ability to buffer the pH of their surroundings.

"Once-a-Day" pharmaceutical composition containing an amount of lithium carbonate from 300 mg to 900 mg, in the form of coated granules having the following composition: lithium carbonate 93%, ethylcellulose 1.7%, talc 0.8%, polyvinylpyrrolidone 4.5%.
摘要:
There is provided a coating composition that masks the undesirable taste of a pharmaceutically active ingredient, i.e. drug or medicine, that is consumed orally. The coating composition has polyvinyl acetate, and a dimethylaminoethyl methacrylate and neutral methacrylic acid ester. Optionally, an alkaline modifier may be included in the coating composition to enhance release of the active ingredient.

摘要:
Foaming compositions which are stable and can be easily produced, in particular, foaming compositions containing water-soluble vitamins such as L-ascorbic acid. Coated granules prepared by granulating acid components containing a di- or tribasic organic acid and, if desired, a water-soluble vitamin such as L-ascorbic acid and coating with polyethylene glycol; and coated granules prepared by granulating alkali components containing a foaming carbonate and, if desired, L-ascorbate and coating with polyethylene glycol. A foaming composition can be obtained by combining the coated granules of the acid components with the coated granules of the alkali components or an uncoated foaming carbonate. A foaming composition can be also obtained by combining the coated granules of the alkali components with an uncoated di- or tribasic organic acid.
摘要:
A method for production of rhPBGD in high scale and use of rhPBGD in a method for treatment or prophylaxis of disease caused by deficiency, in a subject, of an enzyme belonging to the heme biosynthetic pathway. The method comprising administering, to the subject, an effective amount of one or more catalyst which is said enzyme or an enzymatically equivalent part or analogue thereof prefreable in combination with a gene therapy of a mutation related to the catalyst. The disease is selected from the group consisting of acute intermittent porphyria (AIP), ALA deficiency porphyria (ADP), Porphyria cutanea tarda (PCT), Hereditary coproporphyria (HCP), Harderoporphyria (HDP), Variegata porphyria (VP), Congenital erythropoietic porphyria (CEP), Erythropoietic protoporphyria (EPP), and Hepatoerythropoietic porphyria (HEP). The catalyst is one or more enzymes selected from the group consisting of delta-aminolevulininic acid synthetase, delta-aminovulinic acid dehydratase (ALAD), porphobilinogen deaminase (PBGD), uroporphyrinogen III cosythetase, uroporphyrinogen decarboxylase, coproporphyrinogen oxidase, protoporphyrinogen oxidase, and ferrochelatase, or an enzymatically equivalent part or analogue therof. In addition the invention relates to the use of rhPBGD. The invention also relates to an expression plasmid pExp1-M2-BB (seq. ID No.1) and to use of a DNA fragment, the EcoR I - Hind III linear fragment (seq. ID No. 2), used for transformation in the hemC disruption strategy for production of rhPBGD expressed in E. coli. .
