  • Patent number: 4988358
    Abstract: A material with chemically induced surface charges is employed to foster formation of mammalian hard and soft connective tissues. The material may be in the form of beads such as ion exchange resins. Bead materials with a negative surface charge stimulate formation of hard tissue within long bones and foster bony repair of defects in parietal bones and in mandibular rami. Beads with positively charged surfaces engender formation of large quantities of soft dense connective tissue when implanted into defects in the cranium or when used as an onlay on the nasal bone surface. The use of such beads or other charged biodegradable materials and the use of other surface charged materials with different physical configurations provides significant improvement in hard and soft connective tissue repair, augmentation and replacement in medical fields such as orthopaedic and maxillofacial surgery.

  • Patent number: 4895808
    Abstract: A method and apparatus for adsorption and detection of adsorbents or analytes. The method and apparatus can be employed in the field for rapid adsorption of analytes and is particularly useful for detection of mycotoxins. A sample to be analyzed is prepared in solution and placed in a test tube. A tube-like adsorption column having a seal and a valve member is forcefully fed into the test tube to force solutions through the valve member into the column and through a filter and adsorbent to trap interference. The semi-purified solution may then be analyzed for the presence of analytes. The column with the purified solution may be further employed with a second smaller adsorption column similarly equipped with a seal and valve member fitting within the first column. In similar fashion the second column may be forced into the first column to expel the solution therein into the second column and through one or more selective adsorbents for different analytes such as one or more mycotixins.
