  • Publication number: 20050014703
    Abstract: The present invention discloses a method for therapeutically treating mammals, including but not limited to humans, to increase the relative insulin producing performance of endogenous pancreatic ?-cells and to cause differentiation of pancreatic epithelial cells into insulin producing ?-cells. Oral administration a DP IV inhibitor causes the active form of GLP-1 to be preserved longer under physiological conditions. The extended presence of GLP-1, in particular in the pancreatic tissue facilitates differentiation and regeneration of the ?-cells already present that are in need of repair. These repaired insulin producing cells can contribute to the correction and maintenance of normal physiological glycemic levels.

  • Publication number: 20040214762
    Abstract: The present invention discloses a method for the modulation of the enzymatic activity of prolyl endopeptidase in various human tissues and their biological effect on intracellular inositol (1,4,5) triphosphate concentration. The present invention also discloses the potentiation of endogenous neurological and intracellular signaling cascades by inhibition of prolyl endopeptidase activity. This invention further discloses the amplification of substance P mediated stimulation of IP3 concentration by inhibition of proline endopeptidase activity. The effect of reduced PEP activity on second messenger concentration indicates a novel intracellular function of this peptidase, which has an important impact on cognitive enhancements due to PEP inhibition.

  • Patent number: 6763620
    Abstract: The invention relates to a steam iron with instantaneous vaporization comprising a water container (2), a steam chamber (32), an anti-drip device (80) and a drip device having a rod (4) which moves axially. According to the invention, the total stroke of the axially-moving rod (4) comprises a first stroke which provides the flow of water through the opening (520) of a module (5) that receives the water from the container (2) via the anti-drip device (80) and a second stroke which simultaneously opens a direct passage for the water to flow from the container (2) to the module (5) and moves the module (5) by opening a larger hole for the water to flow from the container to the steam chamber.

  • Patent number: 6725586
    Abstract: The invention concerns a flash iron comprising a water reservoir (2), a flash chamber (32) and a drip device having an axially mobile rod (4) whereof the total stroke comprises a first travel enabling the steam to flow towards the orifice (520) of a module (5) and a second travel moving the module (5) by opening a wider orifice (220) for water passing from the reservoir (2) to the flash chamber (32). The invention is characterised in that the tightness between the reservoir (2), the module (5) and the flash chamber (32) is provided by a first compressed seal, and the tightness between the rod and the module is provided by a second compressed seal, the two seals being parts of one and the same elastomeric component (52) borne by the module (5).

  • Publication number: 20040058876
    Abstract: The present application relates to the secondary binding site of dipeptidyl peptidase IV, its relationship amongst substrates and to the modulation of substrate specificity of dipeptidyl peptidase IV (DP IV, synonym: DPP IV, CD26, EC 3.4.14.5). The application relates further to compounds that bind to the secondary binding site of DP IV and their use to modulate the substrate specificity of DP IV; methods of treatment of various DP IV mediated disorders; and screening methods for the identification of secondary binding sites on DP IV and DP IV-like enzymes.

  • Publication number: 20040043919
    Abstract: The present invention discloses a method for therapeutically treating an animal, including a human, for psychosomatic, depressive and neuropsychiatric diseases, such as anxiety, depression, insomnia, schizophrenia, epilepsy, spasm and chronic pain. Administration of a suitable attractin inhibitor causes the reduction of activity in the enzyme attraction or in isoforms thereof in the brain of mammals and leads as a causal consequence to a reduced degradation of the neuropeptide Y (NPY) and similar substrates. Such treatment will result in a reduction or delay in the decrease of the concentration of functionally active neuronal NPY (1-36). As a consequence of the resulting enhanced stability of the endogenous NPY (1-36), NPY activity is prolonged thereby resulting among other things in functionally active NPY Y1 receptor activity thereby facilitating antidepressive, anxiolytic, analgesic, t antihypertension and other neurological effects.
