Abstract: The invention relates to an earth drilling device (1) for boring a borehole into the soil and/or for drawing a line (9) into an underground passage, comprising at least one system line (4, 6) extending from the earth drilling device to a start region, wherein the system line is designed in an electrically insulating manner.

Abstract: A boring element of a ground boring device includes a housing having a receptacle, a transmitter arranged in the receptacle of the housing and supported in the receptacle for movement in a longitudinal-axial direction of the boring element, and a front buffer connecting the transmitter with the housing. The transmitter moves towards a rear in the receptacle as a result of a deformation of the front buffer, when a rear percussive impulse is applied to the boring element, without the transmitter coming directly into contact with another part of the boring element.

Abstract: The invention relates to the analysis and identification of genes that are modulated in transplant rejection. This alteration of gene expression provides a molecular signature to accurately detect transplant rejection.

Abstract: The invention provides methods for predicting and compositions for use in the prediction of rheumatoid arthritis (RA) based upon the simultaneous measurement of at least two biomarkers in a biological sample. The invention further relates to methods for following the efficiency of a treatment against RA and to methods for identifying test substances that are likely to prevent or diminish RA.

Abstract: The invention provides a rapid high throughput screening process to identify genotoxic compounds. This is accomplished by using a set of biomarker predictor genes that selectively screen for genotoxic or non-genotoxic compounds.

Abstract: Disclosed are genes and peptides whose expression is correlated to the prevalence of coronary artery disease. Also provided are methods of prognosis, diagnosis and methods of monitoring coronary artery disease based on the measurement of gene expression.

Abstract: The present invention relates to genes whose expression is correlated to the prevalence of coronary artery disease. In particular, the invention relates to methods of prognosis, diagnosis and methods of monitoring coronary artery disease based on the measurement of gene expression. In addition, the present invention relates to methods of screening compounds for use in treatment of coronary artery disease as well as kits and arrays for use in identifying coronary artery disease.

Abstract: The invention relates to a process for providing a stable crystalline form of a fine-milled salbutamol sulfate, which can be produced, stored and used while maintaining the aerodynamic properties required for inhalation thereof, which comprises the steps of

Abstract: In order to control and optimize the amount of inhalable active substance released when drugs are administered as inhalation powders, the invention calls for the use of auxiliaries consisting of mixtures of coarser particles (average particle size>20 .mu.m) and finer particles (average particle size<10 .mu.m).
