Abstract: The present invention concerns a new analytical method for qualitative and quantitative detection of short nucleic acid sequences, preferably a DNA oligonucleotide or a modified DNA oligonucleotide such as antisense oligonucleotides or fragmented nucleic acid sequences of about 8-50 nucleotides in length. The invention relates to the introduction of modified nucleic acids into an oligonucleotide probe that hybridizes to the target sequence such that amplification and quantitation of the short nucleic acid sequence is enabled and sensitivity and specificity of the reaction is increased. The invention also embraces test kits for performing nucleic acid amplification to detect and quantitate short nucleic acid sequences and processes for preparing such and the use of new analytical methods.

Abstract: In the device for limiting the belt forces generated in cases of restraint in safety belts of vehicles described in the specification, a band-shaped component is provided with a longitudinal slot and a bolt-shaped widening body is engaged in the longitudinal slot. The widening body is wider than the slot so that, if a predetermined belt force is exceeded, relative displacement between the component and the widening body will occur, causing widening of the component. In order to maintain the belt force level required for widening as constant as possible along the displacement path, a shaping body acts on the component to restore its shape after widening. The shaping body has two cutting-edge-like wings aligned essentially at right angles to the plane of the component, the wings being arranged to act on the opposite longitudinal sides of the component at an acute angle with respect to the direction of the force applied to the device.
