Patent PT-733103-E (PT)
Inventor: FLOTTE TERENCE R
IPC: A61K48/00
Filed: 1994-11-03
Abstract: Adeno-associated virus (AAV) vectors may have utility for gene therapy but heretofore a significant obstacle has been the inability to generate sufficient quantifies of such recombinant vectors in amounts that would be clinically useful for human gene therapy application. Stable, helper-free AAV packaging cell lines have been elusive, mainly due to the activities of Rep protein, which down-regulates its own expression and reverses cellular immortalization. This invention provides packaging systems and processes for packaging AAV vectors that efficiently circumvent these problems by replacing the AAV p5 promoter with a heterologous promoter and that allow for substantially increased packaging efficiency.

Patent FI-822723-L (FI)
Inventor: BATTIGELLI JEAN
IPC: D04H1/00
Filed: 1982-08-05
Abstract: The invention relates to the distribution on a receiving device of fibers carried by a gas current. To improve the distribution, the gas current carrying the fibers is subjected to the action of a gas layer which envelopes the current and of which the direction of flow in a plane tangent to the gas current differs from that of the gas current. The action of the gas layer results in an expansion of the current carrying the fibers. The invention is particularly useful where the fibers are received on a collecting device such as a foraminous conveyor belt, of large width.
