摘要:
A method for detecting coronary artery disease for a human patient from the general population and staging the disease, if detected; the method comprising performing the step of testing a sample from the patient for a clinically significant presence of a second marker comprising a malondialdehyde-modified atherogenic protein that is recognized by a scavenger receptor on a macrophage; and performing at least one of the following steps of either testing a sample from the patient for a clinically significant presence of a first marker comprising an oxidized atherogenic protein that is no longer recognized by a low density lipoprotein receptor but is recognized by a scavenger receptor on a macrophage; or testing a sample from the patient for a clinically significant presence of a heart protein; wherein the results from the first step and at least one of the other steps indicates whether the level of the marker in the sample from the individual is clinically significant.
摘要:
The invention relates to plasminogen activators obtained by expression of fused cDNA encoding fragments of human tissue-type plasminogen activator (t-PA) and of human urokinase-type plasminogen activator (u-PA), by combining the fibrin-affinity of t-PA with the fibrin-specificity of u-PA in the single chain form (scu-PA) and,or with the enzymatic activity of u-PA having the two-chain form (tcu-PA). It is preferably a hybrid molecule obtained by fusion of at least a region part of the NHz-terminal region of t-PA to at least a part region of the COOH-terminal region of scu-PA, most preferably the NH 2 -terminal amino acids 1 to 263 of t-PA, fused to the COOH-terminal amino acids 144 to 411 of scu-PA. The invention relates further to a recombinant DNA molecule which yields said hybrid plasminogen activators; the respective mammalian expression vector containing said DNA sequence; a transfected mammalian cell line which comprises said recombinant DNA molecule; and to the method for the preparation of plasminogen activators.
摘要:
Plasminogen activators of the tissue-type and plasminogen activators of the urokinase-type appear to have a synergistic action in vivo when administered together as thrombolytic agents. This can be used in pharmaceutical compositions and in methods for the preparation and use thereof.
摘要:
Chimeric plasminogen activators comprising at least the enzymatic region of urokinase-type plasminogen activator in combination with polypeptide material from another source, will sometimes show improved thrombolytic potency in vivo. The other polypeptide material is preferably a fragment, without substantial fibrin-affinity from the non-enzymatic portion of tissue-type plasminogen activator. The most preferred product is a chimeric molecule comprising aminoacids 1 to 3 and 87 to 274 of tissue-type plasminogen activator fused to aminoacids 138 to 411 of urokinase-type plasminogen activator. These products may occur in single-chain or two-chain form and may be used in pharmaceutical compositions for the treatment of thromboembolic diseases.
摘要:
A device delivering a movement in response to cold, as an imput signal, generated by the expansion of a cryogenic liquid such as freon, butane or propane. The device comprises a shape memory alloy element located in the stream of the escaping expanded gas and changing from a warm to a cold form when struck by such gas stream. Can for instance be used for commanding a valve or for detecting the level of a cryogenic liquid.

摘要:
Warning device to signal the passing of a predetermined temperature level in the environment thereof, comprising heat-conducting fixing means and a cylindrical first tube (9) enclosing a spring element with shape memory effect (11) and a telescoping second tube (12) which can be displaced by said spring element acting in its extended position as a signal.
