Abstract: The present invention relates to a process for preparing anthrax protective antigen protein from E.coli using fed batch culture. This process creates a constitutively expressing system for rapid, efficient, cost-effective and high-level production of anthrax PA from E.coli. The steps of the process involves, transforming E.coli DH5.alpha. cells with the recombinant constitutive expression plasmid containing the PA gene to obtain recombinant DH5.alpha.  cells and testing the PA expression by lysis of said cells followed by denaturing gel electrophoresis and Western Blotting technique using PA  antibodies. This is followed by fermentation and harvesting of the high cell density cells. The said cells are solubilized using 6-8 Molar Urea and separated by centrifugation. The urea denatured PA is isolated from said supernatant and purified and thereafter eluted.

Patent CA-2466142-A1 (CA)
Inventor: BURGERMEISTER ROBERT
IPC: A61F2/82
Filed: 2004-05-03
Abstract: The present invention consists of a main artery stent (the main stent) that is placed in the main artery and a second scent that is placed into the side branch (the side branch stent), the two stents constituting a complete treatment for a stenosed arterial bifurcation. Both stents are preferably drug eluting. The main stent would optimally be one that has a reasonably small area of each cell after the stent is deployed, but also has a large perimeter length for each cell. The stent delivery system for the side branch scent has an attached main guide wire tube that can be advanced over a main guide wire and a central lumen that is advanced over a guide wire placed into the side branch. The structure of the side branch scent delivery system allows the side branch stem to achieve the correct angular orientation and longitudinal position when it is advanced over the two guide wires.

Patent CA-2469616-A1 (CA)
Inventor: AIKEN JAMES W
IPC: A61K31/4245
Filed: 2002-12-12
Abstract: A method for treating or preventing ophthalmic disorders comprising the administration of one or more aldosterone receptor antagonists that contain a 9,11-epoxy moiety, such as eplerenone is disclosed. The method results in a reduction of intraocular pressure which treats or prevents the ophthalmic disorders. Among the disorders are intraocular hypertension, glaucoma, low tension glaucoma, age-related macular degeneration (AMD), macular edema, and diabetic retinopathy. As glucocorticoids and mineralocorticoids also cause the retention of ions, such as sodium and potassium, where aldosterone receptors are located, aldosterone receptor antagonists that contain a 9,11-epoxy moiety, such as eplerenone, also can be administered to modulate the intraocular concentration of ions. Thus, aldosterone receptor antagonists can be administered to maintain an intraocular ionic environment that is beneficial to intraocular cell survival.
