A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

Mosquitoes were orally infected with the chikungunya virus. Midguts were dissected at day 5 post-infection, fixed and permeabilised. Virus is shown in red (anti-E2 protein, cyanine 3), the actin network in green (phalloidin 548) and nuclei in blue (DAPI).

An efficient route to two 3-O-acyl-2-deoxy-4,6-O-isopropylidene-2-trichloroacetamido-D-glucopyranosyl trichloroacetimidate donors is reported. As demonstrated for the 3-O-acetyl derivative, these building
blocks are exquisite b-D-glucosamine donors when reacted either with simple alcohols or with complex oligosaccharides. Besides, their protection pattern is compatible with selective deprotection and subsequent chain elongation at O-3 of the newly incorporated glucosamine residue.
