  • Patent number: 7238371
    Abstract: The invention provides proteinoid microsphere made up of a mixture of thermally condensed amino acids that are crosslinked with a bis dithiol crosslinker reagent. The proteinoid microspheres of the invention may be used to encapsulate a material or a compound and to provide slow, sustained or timed release of the material or compound. The proteinoid microspheres are stable in solution until exposed to a reducing agent. However, the in vivo environment provides a sufficient reduction potential to provide slow, sustained release of materials contained therein from the proteinoid microspheres of the present invention.

  • Publication number: 20070134813
    Abstract: Disclosed are screening processes for identification of compounds that may inhibit complex formation between C-reactive protein and fibronectin. Compounds identified by the disclosed methods may be utilized to inhibit the target analytes that are known to occur during skin aging as well as during the course of several diseases. Accordingly, inhibitory compounds identified by the disclosed methods may be utilized to prevent and treat damaged tissue, inflammatory conditions, cardiovascular conditions, renal conditions, periodontal conditions and obesity, among other conditions. For example, the compounds identified by the disclosed methods may be utilized to treat tissue that has suffered trauma, e.g., burns or wounds, as well as tissue that is inflamed due to any of several causes.

  • Publication number: 20050131287
    Abstract: The premature rupture of amniotic fluid (PROM) may be discovered through a number of inventive means. Methods of evaluating whether PROM is present include; a) through the testing of the pH of vaginal fluids using an irreversible pH test; b) through the detection of analytes (e.g. enzymes) specific to amniotic fluid in the vaginal fluids; c) though the detection of hydrogen peroxide (H2O2) in the vaginal fluid; and d) through the detection of cholesterol in vaginal fluid. While individually indicative of PROM, it is desirable to combine at least two of these techniques to yield a powerful tool of even greater reliability. Test devices and feminine hygiene pads into which the test methods may be incorporated are also included herein.
