    Biophys J 87:4259-70. 2004
    ..These results suggest that the influence of a nonionic polymer or plasma protein on RBC aggregation is simply a consequence of its size in an aqueous environment, and that the specific type of macromolecule is of minor importance...

    J K Armstrong
    Department of Physiology and Biophysics, Keck School of Medicine, University of Southern California, Los Angeles, CA 90033, USA
    Biorheology 38:239-47. 2001
    ..The copolymer coating technique is simple and reproducible, and we believe it will prove to be a useful tool to help address some of the longstanding questions in the field of hemorheology...
  3. ncbi Aggregation of human RBC in binary dextran-PEG polymer mixtures
    B Neu
    Department of Physiology and Biophysics, Keck School of Medicine, University of Southern California, Los Angeles, CA 90033, USA
    Biorheology 38:53-68. 2001
    ..Our results thus suggest the merit of further studies of red blood cell aggregation in binary polymer systems...

    M Y Wang
    Division of Neurosurgery, Childrens Hospital of Los Angeles, 1200 NorthState Street, Los Angeles, CA 90033, USA
    Neurosurgery 49:962-7; discussion 968. 2001
    ..However, bone wax locally interferes with osteogenesis, and its use is avoided when bone fusion is critical. We describe the use of a Pluronic copolymer blend as a biocompatible, absorbable, hemostatic agent...
  5. ncbi Electrophoretic mobility of human red blood cells coated with poly(ethylene glycol)
    B Neu
    Department of Physiology and Biophysics, Keck School of Medicine, University of Southern California, 1333 San Pablo Street, Los Angeles, CA 90033, USA
    Biorheology 38:389-403. 2001
    ..Our results are consistent with the effects of attached PEGs on RBC aggregation and surface antigenic site masking, and suggest the usefulness of electrophoretic mobility techniques for studies of bound neutral polymers...
