摘要:
The present invention relates to recombinant albumins fused with poly-cysteine peptide and methods for preparing the same, more precisely recombinant albumins in which cysteines that can be used for drug binding are amplified at N-terminal and C-terminal of the albumin and methods for preparing the same. The recombinant albumin of the present invention demonstrates improved albumin-drug conjugation efficiency when it is used for drug delivery system, indicating that it can effectively deliver a large amount of drug to a target tissue. At the same time, the recombinant albumin of the present invention can be used as an excellent drug deliverer with reduced side effects, compared with the conventional albumin carriers, by regulating the amount of drug conjugated to each unit of albumin by regulating the number of cysteine fused thereto. In addition, the recombinant albumin of the present invention can be used for the screening of a novel drug and for the non-invasive real-time diagnosis and treatment of disease by combining with a fluorescent material or a contrast agent for molecular imaging.
摘要:
A mechanical diagnostic probe is used to determine the thickness of articular cartilage, so that any degeneration in the articular cartilage can be detected at an early stage. The probe advantageously allows for calibrating the speed of the ultrasound in situ thereby allowing for more accurate measurements of the tissue thickness. The probe also can be used to monitor the condition of the cartilage after surgery and/or after or during physical rehabilitation of the cartilage. The probe is comprised of a probe handle and a probe, which is comprised of an ultrasonic transducer, strain-gauges, and a linear displacement actuator. A predetermined displacement then is applied to the indenter tip and a computer program is then used to analyze the results.
