Publication number: 20130065811Abstract: The need for a means to formulate fluid compositions for use in water-soluble unit dose articles having higher levels of water is met by incorporating a di-amido gellant into the fluid composition. The di-amido gellant also simplifies the addition of ingredients to water-soluble unit dose articles, such as microcapsules, that are typically added as aqueous suspensions or slurries.Type: ApplicationFiled: September 4, 2012Publication date: March 14, 2013Inventors: Susana FERNANDEZ-PRIETO, Isabelle GUIMET, Regine LABEQUE, Walter August Maria BROECKX, John SMETS

Publication number: 20130059000Abstract: A process for making hemoglobin based oxygen carrier (HBOC) containing pharmaceutical composition suitable for oral delivery and the composition formed thereby are described. There are three exemplary composition configurations which include (1) hemoglobin-loaded nanoparticles solution, (2) enteric-coated hemoglobin capsules and (3) enteric-coated hemoglobin tablets. To facilitate the bioavailability and bio-compatibility of hemoglobin, intestinal absorption enhancers are added in each of the HBOC formulations. Protective layers ensure delivery of an intact hemoglobin structure in intestinal tract without degradation in the stomach. The HBOC formulations may be used for preventive or immediate treatment of high altitude syndrome (HAS) or for treatment of hypoxic conditions including blood loss, anemia, hypoxic cancerous tissue, and other oxygen-deprivation disorders.Type: ApplicationFiled: August 23, 2012Publication date: March 7, 2013Inventors: Bing Lou WONG, Sui Yi KWOK

Publication number: 20130037978Abstract: Capsules and similar objects are made from materials having diamond (sp3) lattice structures, including diamond materials in synthetic crystalline, polycrystalline (ordered or disordered), nanocrystalline and amorphous forms. The capsules generally include a hollow shell made of a diamond material that defines an interior region that may be empty or that may contain a fluid or solid material. Some of the capsules include access ports that can be used to fill the capsule with a fluid. Capsules and similar structures can be manufactured by growing diamond on suitably shaped substrates. In some of these methods, diamond shell sections are grown on substrates, then joined together. In other methods, a nearly complete diamond shell is grown around a form substrate, and the substrate can be removed through a relatively small opening in the shell.Type: ApplicationFiled: October 18, 2012Publication date: February 14, 2013Applicant: Terraspan LLCInventor: Terraspan LLC
