A supported liquid membrane (SLM) containing a resorcinarene carrier has been used for the selective transport of erythritol, threitol, ribitol and xylitol from concentrated (1.0-0.01 M) aqueous solutions. The membrane is made of a microporous polytetrafluoroethylene film impregnated with a
Some newly designed surface-active phosphates were investigated with respect to their capacity to inhibit caries lesion formation in vitro. On the labial or buccal surfaces of sound human third molars, windows were prepared for investigation. One half of each window
Differently protected erythro and threo furanoid glycals were synthesized by selenoxide elimination when phenyl 1-selenoglycosides were treated in oxidizing conditions (tBuOOH, Ti(O(i)Pr)(4), Et(2)(i)PrN). The phenyl 1-selenoglycosides were obtained from methyl 2-deoxy-D-erythro-pentofuranoside by protection of the primary hydroxyl or both hydroxyls
Invariant natural killer T (iNKT) cells are restricted by the non-polymorphic MHC class I-like protein, CD1d, and activated following presentation of lipid antigens bound to CD1d molecules. The prototypical iNKT cell agonist is α-galactosyl ceramide (α-GalCer). CD1d-mediated activation of iNKT
PM2.5 samples were collected from June to December 2005 in Potsdam, New York and analyzed for polar organic compounds by GC/MS. The major compounds that were identified in the samples included 2-methyltetrols (2-methylthreitol and 2-methylerythritol), levoglucosan, cispinonic acid, and mannitol.
