Abstract: The present invention relates to recombinant vaccinia viruses which are derived from the modified virus Ankara (MVA) and which contain a DNA sequence which codes for a foreign antigen. The invention also relates to vaccines which contain a virus of this type in a form suitable for injection, as well as to a method for the preparation thereof. Furthermore, the invention relates to the use of a recombinant vaccinia virus MVA for the preparation of heterologous proteins in eukariotic cells.

Abstract: A transport system for shipping microbiological specimen samples which maintains the life of the bacteria contained in the sample and protects the environment from escape of samples comprises:(a) a first container provided with removable closure and containing a medium for storing the sample, and(b) a second container provided with a removable closure cap having an elongate chamber into which one end of a rod disposed therein can be pushed, said rod bearing a swab at its other end,the dimensions of the first and second containers, of the chamber in the closure cap and of the rod carrying the swab being so selected that the first container and a rod inserted therein in the medium and carrying the swab can be contained in the second container closed by the closure cap.

Abstract: There is disclosed a method of treating or preventing viral infections in plants wherein an animal interferon is applied to the plants.

Abstract: A method for the solid phase synthesis of multi-sulfated peptides comprising coupling side-chain unprotected hydroxyamino acids to the peptide chain utilizing benzotriazol-1-yl-oxy-tris (dimethyl)-phosphonium hexafluorophosphate (BOP) as a coupling reagent.

Abstract: According to the invention, a piston fit filter/dispenser vial and method of using same is provided. The vial comprises a conventional filter, for example a piston fit serum filter closing the lower end of the vial and a closure having a pressure source fitting closing off the upper end of the vial. The vial also includes a transfer tube having a first end inside the vial adjacent to the filter and a second end outside vial. Filtrate, for example filtered blood serum, within the vial may be transferred in predetermined aliquots to one or more awaiting sample containers from the vial by applying a predetermined volume of air from a pressure source via the pressure source fitting whereby displaced serum is forced up the transfer tube and out of the vial.

Abstract: Preparation of novel polypeptide sequences spanning amino acid position 61 of the ras protein, said sequences being characterized as containing a leucine in that position instead of the glutamine found in normal ras protein, the utilization of such polypeptides to prepare immunogen compositions utilizing such polypeptide covalently linked to immunogenic carrier materials, the production of antibodies elicited by such polypeptides, the screening of such antibodies to provide monoclonals specific to the P21Tleu61 transforming protein and to immunoassay and use in immunochemical methods employing such antibodies to determine the presence of the p21TLeu61 transforming protein.

Abstract: A process for the manufacture of compounds of the general formula ##STR1## wherein R.sup.1 signifies hydroxy or an etherified hydroxy group, and of zeaxanthin by converting a compound of the general formula ##STR2## wherein R.sup.1 has the above significance, in an inert organic solvent into the acetylenide and reacting this with methyl vinyl ketone, reducing the alcoholate obtained or the alcohol (obtained after hydrolysis of the alcoholate) of the general formula ##STR3## wherein R.sup.1 has the above significance, and subsequently hydrolyzing to give the compound of formula IV and, if desired, converting the compound of formula IV obtained into zeaxanthin.

Abstract: Previously hydroformed feedstocks are upgraded to improve their octane rating by contacting said feedstocks in the presence of hydrogen with a sulfactivated catalyst comprising a metallic hydrogenation component, such as a platinum group metal, in combination with a crystalline aluminosilicate zeolite having uniform pore openings of about 5 Angstrom units. In its more specific aspects, the catalyst further contains a Group II-B metal such as zinc.
