We describe a reversed-phase HPLC method for determination of total mycophenolic acid (MPA), its free concentration (MPAf), and the glucuronide metabolite (MPAG), based on simple sample preparation and gradient elution chromatography. The compounds were quantified in parallel by absorbance at 254 nm and 215 nm in the internal standard mode. Linearity was verified up to 50 mg/L for MPA and up to...
MAGE-encoded antigens, which are expressed by tumors of many histological types but not in normal tissues, are suitable candidates for vaccine-based immunotherapy of cancers. Thus far, however, T-cell responses to MAGE antigens have been detected only occasionally in cancer patients. In contrast, by using HLA/peptide fluorescent tetramers, we have observed recently that CD8(+) T cells specific ...
BACKGROUND Intoeing is a frequent gait problem in children with cerebral palsy. It is essential to determine the cause(s) of intoeing when surgical intervention is being planned. The purpose of this study was to evaluate the prevalence of various causes of intoeing in children with cerebral palsy and to determine whether the causes differ between children with bilateral and those with unilatera...
Anthony D. Stone Synopsys, Inc Abstract This whitepaper is designed to provide a basic understanding of the main concepts of the DO-254 compliance specification for electronic component design. It outlines the major steps involved in a DO-254 compliant ASIC/FPGA design and verification process, and explains how differentiating tool features can be mapped to enhance and facilitate critical stage...
