摘要:
In a method and apparatus for the longitudinal and lateral guidance assistance to the driver of a vehicle, longitudinal guidance assistance is performed as distance regulation for regulating the distance between the vehicle and a preceding guide vehicle. Lateral guidance assistance is optionally carried out as an object tracking regulation for guiding the vehicle according to a displacement lane of a preceding guide vehicle, as a lane tracking regulation for guiding the vehicle along a marked driving lane, or as combined lane object tracking regulation. The lateral guidance assistance is then available only when the distance regulation is active and when the distance between the vehicle and the guide vehicle is smaller than a predefined distance limit and/or when a shaft angle as a viewing angle from the vehicle to the guide vehicle is smaller than a predefined angle limit.

The present invention relates to desulfatohirudins, to the preparation thereof, to pharmaceutical compositions containing these compounds, and to the use thereof.The desulfatohirudins of this invention correspond to hirudin in biological activity and are therefore particularly useful for inhibiting blood clotting.
摘要:
The invention relates to a method for isolating anionic organic substances from aqueous systems using polymer nanoparticles with cationic pH-sensitive surface groups. Extraction can be carried out directly from diluted solutions, biological media (blood plasma, serum, urine, etc.) and complex buffer systems (e.g. PCR preparations contain detergents) without prior derivatization of the samples or addition of binding buffers. After separation from the surrounding medium the conjugates of the corresponding substances and polymer nanoparticles obtained in this manner can be purified through additional washing steps and effectively desalinated. Owing to the pH-sensitivity of the basic surface groups, the bound substances can be released in a targeted manner after separation by modification of the pH of the medium. By using volatile bases contamination of the released samples with ionic residues can be avoided. By adding small quantities of SDS and acetonitrile during the separation stage, the sensitivity of the method can be raised further, especially when the substance to be isolated are present in low concentrations (
摘要:
The present invention relates to a new content substance found in leeches (Hirudo medicinalis), the derivatives of this abbreviated at the N-terminus and the C-terminus, and the desulfated derivatives therefrom as well as a process for the production of these compounds, and their use. These compounds possess thrombin-inhibiting properties and can be used to inhibit clotting in human and animals, for blood conservation, or as reagents for the analytical determination of thrombin.
摘要:
The present invention relates to an adsorbing material which comprises at least one porous functional solid, e.g. a zeolite, incorporated in a polymer matrix. The adsorbing material contains the porous functional solid in an amount of 45 to 80 wt. %. The polymer matrix comprises at least one organic polymer, particularly selected from thermoplastics, and has a secondary pore volume in addition to the primary pore volume of the porous functional solid. Further, the present invention is directed to a shaped article, which comprises or consists of the afore-mentioned adsorbing material, to a method for its preparation and to its use. The present invention is finally conerned with the use of specific rheological additives, in particular waxy components, which function as pore-forming agents in the preparation of shaped articles.
摘要:
A proteinase inhibitor which has the sequence of amino acids 21 to 147 of human bikunin, in which at least one amino acid residue has been replaced by another naturally occurring amino acid. Such proteinase inhibitor is useful in pharmaceutical compositions.
摘要:
The present invention relates to a peptide having essentially the amino acid sequence of pancreatic secretory trypsin inhibitor (PSTI). The present invention also relates to variants of such peptide wherein one or more of the amino acids in the original sequence are replaced by other amino acids. These peptides show an advantageously modified specificity in their inhibotory action. A method of preparation of the peptides and their pharmaceutical use is also described.
摘要:
The present invention relates to polypeptides, to a process for isolating them from sea-anemones (Actinaria), preferably from Anemonia Sulcata, and their use as polyvalent isoinhibitors for proteases, peptidases and esterases such as trypsin, chymotrypsin, plasmin and Kallicrein.
