  • Publication number: 20180366310
    Abstract: The present invention relates to the technical field of ionizing a gaseous substance, in particular the ionizing or ionization of a gaseous substance in preparation for its analysis. A device is intended to make a discharge gas and a test substance ionizable in a flow-through mode without essentially destroying or fragmenting the sample substance. In order to avoid a high expenditure in terms of construction and equipment, the device is intended to be usable under ambient conditions and to ensure a high sensitivity in a possible analysis of an ionized substance. To this end, an ionizing device is used for flow-through ionization of a discharge gas and of a sample substance at an absolute pressure of more than 40 kPa in the ionizing device during ionization. The ionizing device comprises an inlet, an outlet, a first electrode, a dielectric element and a second electrode.

  • Publication number: 20170319068
    Abstract: For characterizing spatial-temporal dynamics of a medium (1) excitable for deformation, an elastic model of the medium is defined. The medium is imaged at consecutive points in time to obtain a series of images. Shifts of structures of the medium (1) between the images of the series are determined. A dynamic description of a temporal development of spatial deformations of a predefined elastic model of the medium (1) is adapted to match the shifts of the structures; and temporal developments of rate of deformation patterns in the medium (1) are identified from the dynamic description.

  • Publication number: 20170128441
    Abstract: The invention relates to a dosage form that is suitable for releasing an active ingredient over a long period of time. For this purpose, the active ingredient is released in two-stages in order to do away with an excessively frequent ingestion of the dosage form. The dosage forms according to the invention are for treating dizziness in humans. They are administered with or after a meal. The concept according to the invention provides that the pharmaceutical form has a dimensionally stable portion which, after ingestion of the dosage form by the patients, does not dissolve in the chyme-filled stomach for a number of hours. In this way, this dimensionally stable portion remains in the stomach until same is evacuated by the so-called “housekeeper waves”. Another portion of the dosage form is formed in such a way that it dissolves within a short time of the patients ingesting same. In this way, a quick invasion of the active ingredient with corresponding plasma levels is ensured.

  • Publication number: 20160348183
    Abstract: A method predicts the residual risk of recurrence after a taxane-free chemotherapy, and the benefit from inclusion of taxane in a chemotherapy regimen in a patient suffering from or at risk of developing recurrent breast cancer. From determination of expression levels of the genes UBE2C, KIF20A, PTGER3, OSBPL1A, CYP27A1, IGKC, in a tumor sample a prognostic score is determined by mathematically combining the expression level values. The prognostic score is compared to thresholds, classifying the patient in three outcome groups. The expression levels of three genes STC1, PCSK6, S100P in the tumor sample are determined, and the expression level values for STC1, PCSK6 and S100P are mathematically combined to yield a predictive combined score, whereas a high predictive combined score generally indicates an increased likelihood of benefit from inclusion of taxane in a chemotherapy regimen in a patient classified to poor and/or intermediate outcome group.
