Patent CA-2219501-A1 (CA)
Inventor: TESTA RODOLFO
IPC: C07D211/90
Filed: 1996-06-28
Abstract: 1,4-Dihydropyridines have been found to counter several processes which play a role in the development of atherosclerotic vascular lesions, such as myocytes proliferation and migration, cholesterol metabolism in macrophages and oxidative modification of low density lipoproteins. They are therefore useful in the manufacture of medicaments for preventing, arresting and reversing atherosclerotic degradation in the arterial walls of humans. The preferred 1,4dihydropyridines for this purpose are lercanidipine, (S)-lercanidipine and (R)lercanidipine.

IPC: H04L12/70
Filed: 1998-03-10
Abstract: A scheme for sharing a common virtual connection identifier between end-nodes, which enable sharing of a common identifier of a sufficient information length at both end-nodes of a virtual connection. In this scheme, the first message containing a first identifier for provisionally identifying a virtual connection commonly between neighboring nodes is exchanged between neighboring nodes, at a time of setting up the virtual connection. Then, the second message containing a second identifier having a larger information size than the first identifier for formally identifying the virtual connection commonly between neighboring nodes, in a form that enables establishing of a correspondence between the first identifier and the second identifier, is exchanged between neighboring nodes through another virtual connection different from the virtual connection to be set up. The correspondence between the first identifier and the second identifier is managed at each node according to the first message and the second message so as to share the second identifier between neighboring nodes.

Title: Commercial production of aprotinin in plants
Inventor: RAO A GURURAJ
IPC: C12N15/15
Filed: 1996-10-31
Abstract: A method for commercial production of aprotinin entails heterologous expression of the protein in plants, preferably at a level such that aprotinin accounts for at least 0.1 % of the total extracted protein. An aprotininexpressing plant also has potential of increased insecticidal resistance by virtue of producing the protein. A genetic map of the integration locus allows identification of plants derived from the transgenic plant. This approach also reveals genetic loci on a plant chromosome that support high levels of gene expression and can be used as site of integration for expression of other genes of interest.

IPC: A63F1/00
Filed: 1998-05-12
Abstract: The method of the present invention involves a card game in which at least two rows of cards, and preferably three rows, are dealt to a player. The player makes a wager for each row of cards. One row of five cards are dealt all face up. The player selects none, one or more of the face up cards from the first row as cards to be held. The cards that are held are duplicated from the first row into all of the other rows. Replacement cards for the non-selected cards are dealt into the first row. Additional cards are also dealt to all of the other rows so that each row is a five card hand. The poker hand ranking of each five card hand by row is determined. The player is then paid for any winning poker hands based on a pay table and the amount of the player's wager.
