  • Patent number: 10183994
    Abstract: The invention relates to anti-TNF? antibodies which are engineered to exhibit a pH-sensitive antigen binding. The invention is preferably directed to anti-TNF? antibody adalimumab (Humira®) or biologically active variants and fragments thereof, wherein the original adalimumab antibody or variant or fragment thereof is engineered by modifications of amino acid sequence within the variable regions. Specifically, the invention relates to adalimumab or biologically active variants or fragments thereof, wherein the CDR domains are modified by replacing one or more amino acid residues by histidine residues.

  • Publication number: 20130289259
    Abstract: Magnetic Resonance Imaging based on 19F instead of 1H opens up new diagnostic possibilities. The 19F nucleus has a high gyromagnetic ratio (40 MHz/T) and a natural isotopic abundance ratio of 100%. In the human body, 19F containing structures are exclusively present in the form of solid salts, e.g. teeth and bones. The J2 relaxation times of the endogenous 19F atoms are extremely short and the MR signal is hardly detectable. The lack of endogenous 19F-based structures with relatively high transverse relaxation times assures a very low background MR signal. Therefore, exogenous 19F-based MRI contrast agents allow for “hot spot” imaging in a way similar to other techniques such as PET. As a useful extension of its diagnostic use, MRI is also proposed for the monitoring of the delivery of bio-active agents such as therapeutic or diagnostic agents.

  • Patent number: 6888827
    Abstract: The invention relates to a communication system which operates in the asynchronous transfer mode (ATM) and which comprises several nodes which form a network and are partly coupled to one another and to terminals, and which each comprise a switch and a control software at least for controlling the relevant coupling field and for the signaling. At least one object of the control software contains detection points in certain states. An object for event handling of the control software is provided for further processing when a detection point is reached. The object for event handling receives data via a special channel from at least one terminal or from another node.

  • Patent number: 6569469
    Abstract: The invention relates to a method for producing an antioxidatively active extract which can be used in particular for stabilizing foodstuffs and cosmetic agents. According to the method, non-enzymatically browned grain germs, or a mixture containing non-enzymatically browned grain germs, is/are extracted using a solvent or solvent mixture (e.g. ethanol or an ethanolic mixture) having an ETN value ranging from 0.6 to 0.8, and the extracting agent is then optionally separated off. The invention also relates to a method for stabilizing unbrowned grain germs in which these unbrowned grain germs are mixed with non-enzymatically browned grain germs.

  • Patent number: 6022107
    Abstract: The purpose of the invention is to determine the topography of retinal reactions with high effectiveness and great certainty. In accordance with the invention, the problem is solved by generating a light-emitting image consisting of surface segments on a surface placed before the eye, and using complete extended m sequences, to brighten and darken the surface segments in each time interval. From the eye reaction signal, with the aid of the cross-correlation function, the reaction functions of the segments are calculated in each time interval, and the quality of the results is evaluated by forming some functions for each time interval. Only reaction signals evaluated as good are added up for the total result. The reaction signal of the eye is monitored for staying within limit values, and when errors are recognized, the m sequences are set back by a number of steps which can be preset, recognized errors in the reaction signal are replaced by the repetition.
