    A second-generation expression system for tyrosine-sulfated proteins and its application in crop protection
    with B. Schwessinger, X. Li, T. L. Ellinghaus, L. J. G. Chan, T. Wei, Joe A., N. Thomas, R. Pruitt, P. D. Adams, M. S. Chern, C. J. Petzold, and Ronald P. C.
    Posttranslational modification of proteins and peptides is important for diverse biological processes in plants and animals. The paucity of heterologous expression systems for PTMs and the technical challenges associated with chemical synthesis of these modified proteins has limited detailed molecular characterization and therapeutic applications. Here we describe an optimized system for expression of tyrosine-sulfated proteins in Escherichia coli and its application in a bio-based crop protecti…Read more

    Purpose To investigate the reliability and accuracy of two pseudo-continuous arterial spin labeling sequences, using two-dimensional gradient-echo echo planar imaging and 3D gradient and spin echo as the readout, respectively. Materials and Methods Each sequence was performed twice 4 weeks apart on six normal control subjects, six elderly subjects with mild cognitive impairment, and one participant with Alzheimer's disease. Eight of these subjects also underwent H 215O positron emission tomograp…Read more
