Abstract: An improved process is disclosed for photodynamically inactivating viruses in red blood cell containing compositions by adding vitamin E or a derivative thereof, such as Trolox, to the red blood cell and photosensitizer containing composition prior to irradiation. Addition of vitamin E or derivative thereof is protective of the red blood cells but not the viruses to be inactivated. Cells irradiated in this manner exhibit reduced leakage of potassium ion, and reduced loss of negative charges from the cell membrane compared to cells treated in the absence of vitamin E or derivative. Red blood cells sterilized by this method are better preserved during storage and their life-time in the circulation in vivo is enhanced.

Abstract: Process for the preparation of polyhalogenated benzotrifluorides, benzotrichlorides and benzoyl chlorides and new trihalogeno-benzotrichlorides and -benzoyl chloridesPolyhalogenated benzotrifluorides can be reacted with chlorides from the series of Friedel-Crafts catalysts to give the corresponding benzotrichlorides, which can be hydrolysed by water in the presence of iron(III) chloride to give the corresponding benzoyl chlorides. These are suitable as intermediate products for the preparation of active compounds for medicaments and feed additives.

Abstract: The present invention concerns the product produced by inactivating extracellular or intracellular pathogenic virus in a biological composition without incurring substantial disruption or inactivation of cells and without significant loss of labile proteins or other valuable biological components also contained therein, the inactivation process comprising subjecting said composition to a virucidally effective amount of irradiation in the presence of (a) a mixture of a compound that quenches type I photodynamic reactions and a compound that quenches type II photodynamic reactions or (b) a bifunctional compound that is capable of quenching both type I and type II reactions, to thereby inactivate said virus while retaining functionality of said composition. The composition is advantageously subjected to the irradiation and the mixture of compounds or bifunctional compound in the presence of an irradiation sensitizer.

Abstract: Articles having a diamond-like protective film formed thereon, each comprising a substrate of a material selected from the group consisting of alloys containing at least Co, Ni, or Fe, ceramics, and glass and which has only a slight affinity for a diamond-like thin film, an Mo film formed on the substrate, and a diamond-like thin film formed further thereon. Such articles are manufactured by a method which comprises holding a grid made of Mo close to the surface of the substrate, bombarding the grid and the substrate surface with a bombarding gas consisting of inert gas atoms of Ar or the like, thereby removing contaminants from the surface and depositing Mo atoms on the substrate surface to form an Mo film thereon, ionizing a low-molecular-weight hydrocarbon or a feed gas capable of producing a low-molecular-weight hydrocarbon upon decomposition or reaction, and then accelerating the resulting ions and depositing the same on the Mo film to form a diamond-like film thereon.
