  • Patent number: 5980501
    Abstract: A passive reservoir for medicament in the form of a plastics bag 1, has a hanging eyelet 2 at its upper end and a lower outlet nozzle 3. The plastics bag 1 has bottom corners 4,5, the left-hand right-angled corner 5 of which encapsulates a data carrier means 6 which carries data relating to a medicament contained or to be contained within the bag 1. The data carrier means is in the form of an electrically and/or magnetically operable device which can emit the data it is carrying in response to activation by a suitable field applied by an external reading device, which can cooperate with a delivery device to control the delivery to a patient of medicament when contained in the bag 1.

  • Patent number: 5980958
    Abstract: A human food product comprises a higher ploidy strain of Fungi imperfecti of which each parent has a genetic growth constraint not shared by the other parent. One parent is for example auxotrophic for two compounds selected from histidine, arginine, leucine and adenine and the other for the other two. The nucleic acid content of the strain is preferably less than 2% by weight. The strain may be made by killing a higher ploidy strain of Fungi imperfecti and simultaneously reducing its nucleic acid content to below 2% by weight by treatment with water. The process may include preparing a higher ploidy strain of edible Fusarium by culturing two auxotrophs thereof together in a medium containing nutrients permitting both to grow and then culturing organisms derived from such culture in minimal medium. The invention is applicable to the production of human food by culturing the strain in conditions such that reversion or partial reversion to the haploid form(s) is minimised.

  • Patent number: 5969215
    Abstract: Plants may be regenerated from stomatal cells or protoplasts of such cells. Prior to regeneration the cells or protoplasts may be genetically transformed by the introduction of hereditary material most preferably by a DNA construct which is free of genes which specify resistance to antibiotics. The regeneration step may include callus formation on a hormone-free medium. The method is particularly suitable for sugar beet.
