  • Patent number: 7273712
    Abstract: The present invention relates to compositions and methods for identification and development of compounds or therapeutic agents that treat pathophysiological conditions arising from inflammatory responses. In particular, the present invention is directed to methods for detecting compounds or therapeutic agents that inhibit or block glycated protein produced induction of the signaling-associated inflammatory response in cells. The present invention provides compositions for and methods of treatment of biological conditions including, but not limited to, vascular complications of type I and type II diabetic induced vasculopathies, other vasculopathies, microangiopathies, renal insufficiency, Alzheimer's syndrome, and inflammation-induced diseases such as atherosclerosis.

  • Patent number: 7015210
    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.

  • Patent number: 5236596
    Abstract: A method and apparatus for dewatering an aqueous coal slurry includes imparting high shear forces to the aqueous coal slurry in the presence of a peptizing agent to render coal particles hydrophobic by stripping clay from the coal particles and peptizing the clay in the aqueous medium of the slurry. The slurry is separating to recover coal particles and the aqueous medium is draining medium from the hydrophobic surface of the coal particles.
