    Abstract: Methods are provided for performing antibiotic susceptibility testing based on the detection of RNA, such as tmRNA, from microbial cells after exposure to antibiotics. In some embodiments, aliquots are obtained from a sample, one of which contains a selected antibiotic. The aliquots, which include growth media, are incubated under conditions suitable for microbial growth, and the microbial cells in each aliquot are removed and lysed, and the lysate is subjected to reverse transcription and amplification in infer the effect of the selected antibiotic on the microbial cells. In one embodiment, a sample containing microbial cells is incubated in the presence of a selected antibiotic and a stimulus is provided to induce the production on m RNA within the microbial cells. The microbial cells are subsequently lysed without substantial degradation of the m RNA within the lysate, and the m RNA is detected to determine the effect of the antibiotic on the microbial cells.

  • Patent number: 8900843
    Abstract: The invention relates to a kit and method for the capture of tumor cells in a body fluid sample. The kit and method of the invention can capture living tumor cells but not non-living tumor cells or cell fragments so that the tumor species can be further identified by further culture of the captured tumor cells. Also, the kit and method of the invention can readily identify whether a sample contains tumor cells and collect these tumor cells for further identification so that the presence of cancer and development of the metastasis and early relapse can be found.

  • Patent number: 8895046
    Abstract: Adult autologous stem cells cultured on a porous, three-dimensional tissue scaffold-implant for bone regeneration by the use of a hyaluronan and/or dexamethasone to accelerate bone healing alone or in combination with recombinant growth factors or transfected osteogenic genes. The scaffold-implant may be machined into a custom-shaped three-dimensional cell culture system for support of cell growth, reservoir for peptides, recombinant growth factors, cytokines and antineoplastic drugs in the presence of a hyaluronan and/or dexamethasone alone or in combination with growth factors or transfected osteogenic genes, to be assembled ex vivo in a tissue incubator for implantation into bone tissue.
