  • Total Synthesis of (-)-Gardmultimine A. [Journal Article]
    Org Lett 2020Chen P, Yang H, … She X
  • The first total synthesis of Gardneria oxindole alkaloid (-)-gardmultimine A has been achieved in 19 steps from d-tryptophan in a fully stereocontrolled manner. This synthesis features (1) an Ir-catalyzed regioselective C-H borylation/oxidation sequence to introduce the C12 methoxyl group, (2) a stereocontrolled oxidative rearrangement of indole to construct the spirooxindole motif, and (3) an Au…
  • Staphylococcus aureus Osteomyelitis: Bone, Bugs, and Surgery. [Review]
    Infect Immun 2020Urish KL, Cassat JE
  • Osteomyelitis, or inflammation of bone, is most commonly caused by invasion of bacterial pathogens into the skeleton. Bacterial osteomyelitis is notoriously difficult to treat, in part because of the widespread antimicrobial resistance in the preeminent etiologic agent, the Gram-positive bacterium Staphylococcus aureus Bacterial osteomyelitis triggers pathologic bone remodeling, which in turn lea…
  • Total Synthesis of (-)-Rhodomollanol A. [Journal Article]
    J Am Chem Soc 2020Gao J, Rao P, … Ding H
  • An asymmetric approach for the first total synthesis of (-)-rhodomollanol A, a highly oxidized diterpenoid, is described. The efficient synthetic strategy features three key transfor-mations: 1) an oxidative dearomatization-induced (5+2) cy-cloaddition/pinacol-type 1,2-acyl migration cascade to build up the bicyclo[3.2.1]octane skeleton; 2) a retro-Dieckmann frag-mentation/vinylogous Dieckmann cy…
  • Resegmentation is an ancestral feature of the gnathostome vertebral skeleton. [Journal Article]
    Elife 2020; 9Criswell KE, Gillis A
  • The vertebral skeleton is a defining feature of vertebrate animals. However, the mode of vertebral segmentation varies considerably between major lineages. In tetrapods, adjacent somite halves recombine to form a single vertebra through the process of 'resegmentation'. In teleost fishes, there is considerable mixing between cells of the anterior and posterior somite halves, without clear resegmen…
  • Self-supervised Multi-view Person Association and Its Applications. [Journal Article]
    IEEE Trans Pattern Anal Mach Intell 2020Vo MP, Yumer E, … Narasimhan SG
  • Reliable markerless motion tracking of people participating in a complex group activity from multiple moving cameras is challenging due to frequent occlusions, strong viewpoint and appearance variations, and asynchronous video streams. To solve this problem, reliable association of the same person across distant viewpoints and temporal instances is essential. We present a self-supervised framewor…
  • Evaluation of the spinal effects of phthalates in a zebrafish embryo assay. [Journal Article]
    Chemosphere 2020; 249:126144Qian L, Liu J, … Li Y
  • Phthalates (phthalate esters, PAEs) are commonly used as plasticizers and are emerging concerns worldwide for their potential influence on the environment and general public health. Thus, identification of the negative effects and involved mechanisms of PAEs is necessary. Herein, we found that embryonic exposure of zebrafish to di-(2-ethylhexyl) phthalate (DEHP) and di-butyl phthalate (DBP) signi…
