Abstract: A payment card has a generally planar body having a first side and a second side, and a plurality of acceptance attributes on the second side. The first side is formed without any acceptance attributes thereon. The first side may include artwork of an issuer of the payment card. The acceptance attributes may include, for example, a signature panel, a cardholder name, a card expiration date, at least one of a bar code and a magnetic stripe, and a card security code. A method of using such a card includes physically presenting the card to a merchant, and viewing, by the merchant, of at least needed ones of the acceptance attributes without the merchant being required to turn the card over.

Abstract: Methods are provided that for producing aqueous formulations of pharmaceutical agents having low aqueous solubility. The methods also provide a simple means of producing the formulation as a sterile product. The drug is physically entrapped by a spatially stabilized matrix comprising a hydrophilic or hydrophilic-hydrophobic block polymer, without being covalently bound to the polymer. The drug formulation is a nanoparticle or sub-nanoparticle in size. In a preferred embodiment the nanoparticles are anisotropic, being much longer than they are wide.

Abstract: Pharmaceutical formulations are provided that increase the systemic bioavailability of camptotheca derivatives; preferably, the camptothecin derivative is 7-ethyl-10-hydroxyl camptothecin, SN-38. The drug is complexed with a stabilizing agent, but is not covalently bound thereto. Anionic or neutral lipids and/or polymers are used as the stabilizing agent, and secondary stabilizing agents and/or other excipients may be incorporated into the formulation as well. Therapeutic methods are also provided, wherein a formulation of the invention is administered to a patient to treat a condition, disorder, or disease that is responsive to camptothecin derivatives. Generally, administration is oral or parenteral.
