    Abstract: Methods are provided for producing a bioscaffold from natural tissues by oxidizing a decellularized tissue to produce a bioscaffold having pores therein. The pore size and porosity is increased to better accommodate intact cells so that live cells can better infiltrate and inhabit the bioscaffold. The bioscaffold may be freeze-dried or lyophilized, sterilized and (optionally) aseptically packaged for subsequent use. A further aspect of the present invention is a bioscaffold produced by the processes described herein. Methods of treatment using the bioscaffold as a graft or as a biomedical implant for implantation are also provided. Also provided are methods of seeding a bioscaffold with mammalian cells, wherein the seeding carried out either in vitro or in vivo, and wherein a bioscaffold produced as described herein is utilized for said seeding.

  • Publication number: 20080305160
    Abstract: The field of the invention is that of oral medicaments or pharmaceutical compositions, in particular of the type including one or more active principles. The aim of the invention is to provide an improved oral medicament to be administered in one or several daily doses and enabling the modified release of active principles (in particular of one active principle), whereby the prophylactic and therapeutic effectiveness of said medicament is improved. This aim is achieved by the oral multimicrocapsule galenic form according to the invention, in which the active principle release is controlled by a dual release trigger mechanism: “time-dependent trigger” and “pH-dependent trigger”.

  • Patent number: 7456150
    Abstract: Systemic delivery of parathyroid hormone to a mammalian host is accomplished by inhalation through the mouth of a dispersion of an N-terminal fragment of PTH. It has been found that such respiratory delivery of the PTH fragment provides a pulsatile concentration profile of the PTH in the host's serum. PTH fragment compositions include dry powder formulations having the PTH present in a dry bulking powder, liquid solutions or suspensions suitable for nebulization, and aerosol propellants suitable for use in a metered dose inhaler.

  • Patent number: 7442387
    Abstract: The present invention pertains to a sized product, which contains a drug, polyethylene oxide with a molecular weight of 2,000,000 or higher, and a specific size controlling agent for polyethylene oxide (substance with the appropriate plasticity and binding force) and wherein at least the above-mentioned specific size controlling agent is uniformly dispersed in the above-mentioned polyethylene oxide, a controlled-release pharmaceutical composition containing this sized product, and a method of manufacturing a controlled-release pharmaceutical composition containing this sized product. A controlled-release pharmaceutical composition with good uniformity of content can be presented by using powder particles of polyethtylene oxide with powder properties suitable for tableting, which is obtained by uniform dispersion of the specific size controlling agent for polyethylene oxide of the present invention.

  • Publication number: 20080260819
    Abstract: A sustained release pharmaceutical composition has been developed. The composition resists dose dumping when broken, crushed or chewed, which enhances the safety of the dosage form should it be accidentally or intentionally physically compromised. In the preferred embodiment, a drug is modified to increase its lipophilicity. In preferred embodiments the modified drug is homogeneously dispersed within microparticles composed of a material that is either slowly soluble or not soluble in water. In some embodiments the drug containing microparticles coated with one or more coating layers. The sustained release composition retards the release of drug, even if the physical integrity of the formulation is compromised (for example, by chewing or crushing) and the resulting material is placed in 0.1N HCl.
