    PAF-Stimulated Protein Tyrosine Phosphorylation in Hippocampus: Involvement of NO Synthase

    The effect of platelet-activating factor (PAF) on protein tyrosine phosphorylation was studied in rat hippocampal slices. PAF caused an increase in the tyrosine phosphorylation of two phosphoproteins, which we...

    Weak and strong basic resins for uranium recovery

    Resins were synthesized by crosslinking of linear polyethyleneimine and subsequent N-methylation. The retention properties of these resins, for copper (pH=0 to 4); for uranium (pH=0 to 3) and for iron (pH=0 to...

    Polyethyleneimine supports for resins with retention properties for heavy metals. Part 3

    Resins with retention properties for copper(II) and uranium(VI)were synthesized by crosslinking of polyethyleneimine with 1,9-dibromononane and 1,10-dibromodecane, and subsequent alkylation with dimethylsulpha...

    Cyclic AMP during development and ageing of the insectCeratitis capitata

    Cyclic AMP was determined during the development of the dipteraCeratitis capitata. The concentration of the nucleotide reaches a peak at apolysis with a sharp decline in the pharate adult stage. A gradual increas...
