    Data analyses of honokiol-induced autophagy of human glioma cells in vitro and in vivo

    AbstractThis article contains raw and processed data related to a research, “Honokiol induces autophagic cell death in malignant glioma through reactive oxygen species-mediated regulation of the p53/PI3K/Akt/mTOR signaling pathway” (C.J. Lin, T.L. Chen, Y.Y. Tseng, G.J. Wu, M.H. Hsieh, Y.W. Lin, R.M. Chen, 2016) [1]. Data were obtained by immunoblotting analyses of light chain 3 (LC3)-II, beclin-1, Akt, and mTOR in human glioma U87 MG cells and mouse glioma tissues treated with honokiol, an active constituent extracted from the bark of Magnolia officinalis, “Honokiol induces autophagy of neuroblastoma cells through activating the PI3K/Akt/mTOR and endoplasmic reticular stress/ERK1/2 signaling pathways and suppressing cell migration” (P.S. Yeh, W. Wang, Y.A. Chang, C.J. Lin, J.J. Wang, R.M. Chen, 2016) [2]. The processed data show the effects of honokiol on induction of autophagy in human glioma U87 MG cells by analyzing levels of LC3-II, p62, and bectin-1, “Honokiol-induced apoptosis and autophagy in glioblastoma multiforme cells” (K.H. Chang, M.D Yan, C.J. Yao, P.C. Lin, G.M. Lai, 2013) [3]. In addition, chloroquine, a lysosomal inhibitor, was administered to the cells to further confirm honokiol-induced cell autophagy. Sequentially, mice with gliomas were created and treated with honokiol. Amounts of phosphorylated and non-phosphorylated Akt and mTOR in glioma tissues were analyzed to determine the possible mechanisms of honokiol-induced autophagy

    Timothy Johnson, M.D., medical editor for ABC News will deliver the principal address and receive an honorary degree at the 154th commencement exercises at the College of the Holy Cross on Friday, May 26, beginning at 10:30 a.m. at Fitton Field. Johnson, one of the nation’s leading medical communicators of health care information, has provided commentary on medical problems and answers for viewers since 1975. In addition to commentary on Good Morning America, Johnson provides on-air analysis of medical news for World News Tonight, Nightline and 20/20. He consults with ABC News regardingcoverage of medical news. He is also medical editor for WCVB-TV, Channel 5 in Boston. Johnson holds joint positions in medicine at Harvard University and Massachusetts General Hospital in Boston. He is the founding editor of the Harvard Medical School Health Letter and co-editor of the Harvard Medical School Health Letter Book. He is also coeditor of the book, “Your Good Health,” published by Harvard Press, as well as co-author with former US Surgeon General Dr. C. Everett Koop of the book, “Let’s Talk,” published by Zondervan in 1992. He originally intended to join the ministry and graduated from the North Park Seminary in 1963. Two years later he decided to enter medicine. Johnson, who is a Phi Beta Kappa graduate of Augustana College, graduated summa cum laude from Albany Medical College and holds a master’s degree in public health from Harvard University. Johnson served as an assisting minister at the Community Covenant Church in West Peabody, Mass.https://crossworks.holycross.edu/commence_address/1012/thumbnail.jp

    Robust energy transfer mechanism via precession resonance in nonlinear turbulent wave systems

    No full text
    A robust energy transfer mechanism is found in nonlinear wave systems, which favours transfers towards modes interacting via triads with nonzero frequency mismatch, applicable in meteorology, nonlinear optics and plasma wave turbulence. We emphasise the concepts of truly dynamical degrees of freedom and triad precession. Transfer efficiency is maximal when the triads' precession frequencies resonate with the system's nonlinear frequencies, leading to a collective state of synchronised triads with strong turbulent cascades at intermediate nonlinearity. Numerical simulations confirm analytical predictions
