  • Patent number: 6410481
    Abstract: The invention relates to water-dispersible granules of a pesticidally active main component of sufficiently high melting point, a liquid pesticidal active substance or pesticidal active substance of low melting point and/or which is not sufficiently biologically active in the solid state, in dissolved form, a solvent or solvent mixture with low volatility, and, if appropriate, further additives or adjuvants. The granules are prepared from an aqueous suspoemulsion of the components by removing the water, for example in a fluidized-bed drier. The novel granules are distinguished by an outstanding spontaneous dispersibility and a good biological activity of the formulations prepared from them.

  • Patent number: 6384202
    Abstract: A DNA sequence is described for the gene therapy of diseases associated with the immune system. In its essential elements, the DNA sequence is composed of an activator sequence, a promoter module and a gene for the active substance. The activator sequence is activated in a cell-specific or virus-specific manner and this activation is regulated by the promoter module in a cell cycle-specific manner. The choice of activator sequence and active substance depends on the indication area. The DNA sequence is inserted into a viral or non-viral vector which is supplemented by a ligand having affinity for the target cell.

  • Patent number: 6358419
    Abstract: Wastewater from the aldolization reaction is purified by adjusting its pH to 0 to 6, followed by extraction with monohydric alcohols having at least 8 carbon atoms, hydrocarbons having at least 6 carbon atoms, and mixtures thereof. In some cases, adjustment of the pH causes the formation of an organic phase, which is separated from the remaining wastewater before extraction.
