Abstract: Antigenic fragments of human Factor VIII polypeptide, pharmaceutical compositions which contain these fragments, and complexes containing these peptides and a carrier protein or peptide.

Abstract: The present invention is related to the antigenic polypeptide sequence of Factor VIII.

Abstract: An antigenic polypeptide of factor VIII comprises a polypeptide included between the Glutamic Acid 1649 and Asparagine 2019, preferably between Arginine 1652 and Arginine 1917 of the polypeptide of factor VIII, or a polypeptide included between Alanine 108 and Methionine 355, or a polypeptide included between Aspartic Acid 403 and Aspartic Acid 725, or a polypeptide included between Lysine 2085 and Lysine 2249.

Abstract: A method and an apparatus for inactivating contaminants in blood products are disclosed. The blood product is flowed past an emitter of type C ultraviolet radiation while controlling the flow of the blood product so that the irradiation doses which are received by the blood product are lower than 640 joules/m2. The blood product is substantially free of nonenveloped viruses after the irradiation. The apparatus includes an emitter of type C ultraviolet radiation placed so as to emit the type C radiation toward the blood product in a quartz tube or a tube made of polymerized material which does not absorb type C radiation. The apparatus also includes a flow meter for controlling the flow rate of the blood product to be treated.

Abstract: The present invention relates to a device for diagnosing and/or quantifying antibodies present in a biological fluid from a patient and which are specific for a reaction associated with an infection with a microorganism, specific for an autoimmune reaction or specific for an allergy. This device includes as a standard a biological sample selected from a pool of blood plasmas from more than 200 healthy patients.

Abstract: A method and apparatus for inactivating contaminants, particularly nonenveloped viruses, in blood products without the need for quenchers in the blood products. The blood product is flowed through a flow meter at a controlled flow rate and subjected to type C ultraviolet radiation, where the irradiation dose received by the blood product is less than 640 joules/m2. The blood product does not contain quenchers when being irradiated, and the blood product retains more than 85% of its Factor VIII activity after being subjected to the radiation. The produced blood product is free of viruses and quenchers, avoiding potential toxicity due to the quenchers. The apparatus includes a source of UVC light, a quartz tube containing the blood product while it is exposed to the UVC light, a flow meter for controlling the flow rate of the blood product to be treated, and a pump. The UV light preferably emits light at 254 nm.

Abstract: A fibrinogen concentrate has a purity of 98% or higher and is free of viral contaminants and proteases. The fibrinogen concentrate is obtained by subjecting a solubilized plasma fraction containing fibrinogen to a viral inactivation chemical treatment using a solvent/detergent, subjecting the resulting viral-inactivated fraction to precipitation in a solution containing an amino acid at an acidic pH to obtain a supernatant, filtering the supernatant to obtain a purified fibrinogen concentrate, and recovering the purified fibrinogen concentrate.

Abstract: The present invention relates to compounds of formula ##STR1## in which Q is N or CH,Ar is a radical chosen from among phenyl and optionally substituted thienyl radicals, it being possible for the substituents to be from one to three substituents: halo, lower alkyl or lower alkoxy,--AA-- represents a divalent radical corresponding to an amino acid forming part of the structure of proteins, it being possible for some functional groups of this radical to be protected, or alternatively, it represents a diacyl radical,n is an integer from 0 to 4 inclusive, andX represents H, OH or Y, ##STR2## in which when n is equal to 1, 2, 3 or 4, Y is then a hydrocarbon radical containing from 1 to 20 carbon atoms,when n is equal to 0, Y is then a hydrocarbon radical containing from 7 to 20 carbon atoms, as well as to the salts and the isomers of these compounds, to a process for the preparation of these compounds, to their application as fungicidal and/or bactericidal agents and to their compositions containing them.
