Abstract: A device and method for secure check processing in a paper check scanning device that scans the identification encoding characters on the surface of a paper check, creating an electronically digitized record of the scanned physical identification indicators, transmitting the digitized record of the indicators to a verification unit, and awaiting validation and acceptance of the digitized record. The digitized record may be validated and accepted either through an electronic processing system or manually by human validation personnel. After the digitized record has been accepted the acceptance notification is sent to the check scanner. Upon receipt of the validation and acceptance of the digitized record of the paper check, the secure check scanner moves the paper check into position and the encoded identification characters on the paper check are altered by removing the area of the paper check containing the identification characters to render the paper check unscannable.

Abstract: Disclosed herein are pharmaceutical compositions comprising carboxyalkylcellulose esters for delivery of pharmaceutically active substances having low solubility in a medium such as water, an acidic aqueous buffer, a neutral aqueous buffer, or a basic aqueous buffer. Also disclosed are methods for making pharmaceutical compositions and methods of administering the compositions.

Abstract: Disclosed herein are pharmaceutical compositions comprising carboxyalkylcellulose esters for sustained delivery of pharmaceutically active substances. The composition comprises: at least one pharmaceutically active agent, and at least one carboxyalkyl cellulose ester comprising an anhydroglucose repeat unit having the structure: wherein: R1-R6 are each independently selected from —OH, —OC(O)(alkyl), and —O(CH2)xC(O)OH, and pharmaceutically acceptable salts thereof, wherein x ranges from 1-3, a degree of substitution per anhydroglucose of —OH ranges from 0.1 to 0.7, a degree of substitution per anhydroglucose of —C(O)(alkyl) ranges from 0.1 to 2.7, and a degree of substitution per anhydroglucose of —O(CH2)xC(O)OH ranges from 0.2 to 0.75, and wherein in pharmaceutically acceptable media, the composition exhibits sustained release of the at least one pharmaceutically active agent.
