The EOS 2D/3D system presented here is a new, low-dose, orthopedic radiodiagnostic device based on Nobel prize-winning X-ray detection technology with special software for 3D surface reconstruction capabilities that finally led to a breakthrough in scoliosis diagnosis with high-quality, realistic buy PLX4032 3D visualization and accurate quantitative parametric analysis. A new concept introducing vertebra vectors and vertebra vector parametric calculations is introduced that furnishes simplified visual and intelligible mathematical information facilitating interpretation
of EOS 2D/3D data, especially with regard to the horizontal plane top view images. The concept is demonstrated by a reported scoliotic case that was readily characterized through information derived from vertebra
vectors alone, supplemented with the current angulation measurement methods in the coronal and sagittal planes and axial vertebral rotation measurements in the horizontal plane, with a calibrated 3D coordinate system suitable for inter-individual comparisons. The new concept of vertebra vectors may serve as a basis for a truly 3D classification of scoliosis.”
“Introduction: To explore the feasibility JAK inhibitor of coupling dried blood spot (DBS) technique with ELISA for the quantification of large molecules, exenatide was used as a model. A method for the quantification of exenatide in human blood was developed
and evaluated. Methods: Exenatide standard and quality control samples prepared in fresh human blood were www.selleckchem.com/products/crenolanib-cp-868596.html spotted on DBS cards and then extracted. The extraction conditions were optimized by comparing different extraction solutions, with/without protease inhibitors, and various incubation times. A competitive ELISA assay was used for quantification of exenatide from DBS samples. Results: The assay range of exenatide standards in blood was 100-5000 pg/mL. The intra-assay precision (%CV) was from 1.2% to 16.3%, and the accuracy (%Recovery) was from 87.5% to 117.0%. The inter assay precision (%CV) was from 1.7% to 14.3%, and the accuracy was from 95.0% to 115.5%. All the above assay parameters met acceptance criteria. Furthermore, the storage stability of exenatide on DBS cards was tested at ambient temperature as well as at 4 C and 70 C. and it was found that change of storage temperature did not affect the stability of exenatide significantly. Discussion: Our results demonstrated a successful coupling of DBS technique with ELISA for quantification of exenatide in human blood, and the DBS-ELISA combination has a great potential to be further applied for the quantification of other large molecule drugs or biomarkers.
