In a screening test method, and a device for implementing the screening test method, a diagnostic substance is provided that contains at least one biomarker connected with at least one ferromagnetic particle, the biomarker binding specifically to a target molecule that is formed by specific pathological prostrate tissue. The diagnostic substance is administered to the blood stream of a patient. A magnetometer is used to detect enrichment of the ferromagnetic particle in the prostrate, as an indicator of a level of the specific pathological prostrate tissue.

In a method for imaging a prostate tumor in which a contrast agent that can be distributed via the circulatory system is administered to the patient, the contrast agent contains at least one type of biomarkers which are bound to a ferromagnetic particle and specifically bind to a target molecule typical of the tumor and formed within the tumor or in a tissue adjacent to the tumor. The imaging ensues with the use of magnetic resonance tomography.
摘要:
An equivalence relationship is created between a) the functional network of the genome and proteome and b) a neuronal network. Both networks represent highly cross-linked feedback systems. The equivalence relationship makes it possible to model the functional network of proteins of and genes by an equivalent artificial neuronal network. The dynamic interaction of genes and regulatory proteins is modeled by a dynamic neuronal network. The method uses information obtained in a temporal sequence of gene expression patterns for identification of causal regulatory correlations, thereby enabling target proteins to be identified on a systematic basis.
摘要:
There is described a method for computer-aided learning of a neural network, with a plurality of neurons in which the neurons of the neural network are divided into at least two layers, comprising a first layer and a second layer crosslinked with the first layer. In the first layer input information is respectively represented by one or more characteristic values from one or several characteristics, wherein every characteristic value comprises one or more neurons of the first layer. A plurality of categories is stored in the second layer, wherein every category comprises one or more neurons of the second layer. For one or several pieces of input information, respectively at least one category in the second layer is assigned to the characteristic values of the input information in the first layer. Input information is entered into the first layer and subsequently at least one state variable of the neural network is determined and compared to the at least one category of this input information assigned in a preceding step. The crosslinking between the first and second layer is changed depending on the comparison result from a preceding step.
摘要:
In a method for diagnosis and treatment of a patient with a tumor relating to prostate cancer, the following steps are implemented. A differential diagnosis of prostate cancer versus prostatitis and/or BPH is conducted on a patient using a cost-effective diagnosis method. If prostate cancer is diagnosed in the patient using a cost-effective measurement method, a characteristic value for the tumor aggressiveness of the prostate cancer is determined. A watchful waiting treatment is implemented with the patient given a characteristic value below a predeterminable first limit value. The size and position of the tumor is determined using a cost-effective method given a characteristic value above the first limit value. A cost-effective ultrasonic theranosis or a conventional therapy is conducted for a size below a second predeterminable limit value. The presence of metastases in the patient is checked, with a cost-intensive method generating image information, for a size above the second limit value. A metastasis treatment is implemented in the event that metastases are present. In the event that no metastases are present, a tumor treatment based on the aforementioned image information generated is implemented.
摘要:
A causal network is used, which describes the regulatory genetic network of a cell such that nodes of the causal network represent genes of the regulatory genetic network and connectors of the causal network represent regulatory interactions between the genes of the regulatory genetic network. This causal network is adapted to the regulatory genetic network using a structure learning method. Using prior knowledge about a selected regulatory interaction between two genes, an a-priori information is determined for the connector representing the selected regulatory interaction. The a-priori information is taken into account for adapting the causal network to the regulatory genetic network using a structure learning method.

摘要:
A diagnostic substance for use in a method for diagnosing prostate diseases contains multiple different coupling molecules that respectively bind to signal molecules (target molecules) of a molecular surface structure of a pathological tissue that is associated with a prostate disease. A first of the coupling molecules specifically binds to signal molecules of cancer tissue, and a second of the coupling molecules specifically binds to signal molecules formed in inflamed tissue. First and second markers are respectively associated with the first and second coupling molecules, the first and second markers being detectable, and differentiated from each other, with a detection device.
摘要:
In a method to determine at least one parameter pertaining to a prostate of a patient, an integrated diagnostic support system implements the following steps. A first risk value for prostate illness is determined using a screening method. In the event that this first characteristic risk value exceeds a first limit value, at least one second characteristic risk value for prostate illness and its location are determined using a method supplying a medical image of the patient. An integrated report system outputs at least one of the characteristic risk values and/or the location. A corresponding device has a mini-laboratory analysis unit for the screening test, an intelligent decision support system for the first characteristic risk value, a first interface with an imaging system, an evaluation system for the medical image for the second characteristic risk value, and a report system with a user interface.
摘要:
A diagnosis substance for application in a method for diagnosis of pathological tissue, contains at least one virus population with virus particles specifically binding to target molecules typical of a specific pathological tissue, with a label that is detectable with the use of a detection device being bound to the virus particles. In a method for production of such a diagnosis substance, the principle of directed biological evolution is applied.
