Abstract: Secrets such as secure session cookies for a web browser can be protected on a compute instance with multiple layers of encryption, such as by encrypting key material that in turn controls cryptographic access to the secret. A compute instance can be instrumented to detect when a process attempts to decrypt this key material so that the process requesting decryption can be compared to authorized or legitimate users of the secret.

Abstract: The invention in one aspect relates to recombinant replication competent adenovirus that can replicate in and lyse a host cell comprising in the genome of the adenovirus a coding sequence for a glycogen synthase kinase-3 (GSK3) protein operably linked to an expression control sequence. It also relates, among others, to means and methods for treatment of cancer with a coding sequence for a glycogen synthase kinase-3 (GSK3) protein operably linked to an expression control sequence, preferably in the context of an adenovirus. This work was funded in part by European Union Horizon 2020 research and innovation programme, Marie-Sklodowska-Curie grant number 643130.

Abstract: Described is a replication competent virus, being capable to replicate and having lytic capacity in host cells, the virus comprising in the genome thereof, at least one DNA sequence coding for a silencing factor functional in reducing expression of a target gene in the said host cells, operably linked to one or more expression control sequences, functional in the said host cells, and the use thereof in the preparation of a medicament and to the use thereof in a method for lysing host cells expressing a virus inhibitory factor.

Abstract: The present invention is concerned with means and methods for producing adenovirus particles comprising a chimeric adenovirus spike protein that essentially lacks a functional knob domain. One aspect of the invention is concerned with a method for producing adenovirus particles comprising providing cells that are permissive for adenovirus replication with an adenovirus vector, with nucleic acid encoding said chimeric adenovirus spike protein and with nucleic acid encoding at least one adenovirus E3 region protein or a functional part, derivative and/or analogue thereof, said method further comprising culturing said permissive cells to allow for at least one replication cycle of said adenovirus virus and harvesting said adenovirus particle.

Abstract: A method for producing viral gene delivery vehicles which can be transferred to pre-selected cell types by using targeting conjugates. The gene delivery vehicles comprise: 1) the gene of interest; and 2) a viral capsid or envelope carrying a member of a specific binding pair, the counterpart of which is not directly associated with the surface of the target cell. These vehicles can be rendered unable to bind to their natural cell receptor. The targeting conjugates include the counterpart member of the specific binding pair, linked to a targeting moiety which is a cell-type specific ligand (or fragments thereof). The number of the specific binding pair present on the viral vehicles can be, for example, an immunoglobulin binding moiety (e.g., capable of binding to a Fc fragment, protein A, protein G, FcR or an anti-Ig antibody), or biotin, avidin or streptavidin. The virus' outer membrane or capsid may contain a substance which mediates entrance of the gene delivery vehicle into the target cell.

Abstract: A method is provided for genetically modifying primate bone marrow cells, comprising isolating bone marrow cells from a primate and, by means which enhance the local concentration of retroviral particles, contacting the isolated bone marrow cells to cells that produce a recombinant amphotropic retrovirus with a genome based on a retroviral vector that contains the genetic information to be introduced into the bone marrow cells. Recombinant amphotropic retrovirus-producing cells, suitable for use in this method also are provided, as are genetically modified primate bone marrow cells with the capacity for regeneration in vivo.

The gene delivery vehicles comprise: 1) the gene of interest; 2) a viral capsid or envelope carrying a member of a specific binding pair, the counterpart of which is not directly associated with the surface of the target cell. These vehicles can be made unable to bind to their natural receptor on the cell. The targeting conjugates are composed of the counterpart member of the specific binding pair linked to a targeting moiety which is a cell-type specific ligand. The number of the specific binding pair present on the viral vehicles can be, for example, an immunoglobulin binding moiety, biotin, avidin, or streptavidin. The outer membrane or capsid of the virus may contain a substance which mediates entrance of the gene delivery vehicle into the target cell.

Abstract: In the manufacture of glazing panels comprising sheets marginally bonded together, in order to simplify and speed up production, an apparatus for effecting bonding between at least one such sheet and one or more members assembled in marginal contact therewith. The apparatus includes treatment means which is carried by a frame. In order to accomodate assemblies of different sizes carried by a support, each beam of the frame is coupled at one end relative to a movable coupling, whereby the end of each beam is movable along another beam in the direction of whose length its end coupling is movable, so that the size of the frame can be adjusted.

Abstract: In the manufacture of glazing panels comprising sheets marginally bonded together, in order to simplify and speed up production, a method of effecting bonding between at least one such sheet and one or more members assembled in marginal contact therewith, comprising bringing the assembly within the sphere of treatment means which is carried by a frame and causing the treatment means to act simultaneously on each side margin of the assembly to bond it together. In an apparatus for performing the method, in order to accommodate assemblies of different sizes carried by a support, each beam of the frame is coupled at one end relative to a movable coupling, whereby the end of each beam is movable along another beam in the direction of whose length its end coupling is movable, so that the size of the frame can be adjusted.

Abstract: An apparatus for manufacturing a glazing panel which includes a pair of glazing sheets separated by an intervening marginal spacer frame formed to a required size and shape from strip material and marginally secured between the pair of sheets. The apparatus comprises a frame forming mechanism which includes guides defining at least two paths for feeding required lengths of the strip material, stops defining a position for the leading ends of the strip material as it is fed, a plurality of bending stations arranged to bend the strip material on at least one of the paths to form frame corner angles at required distances from the stops, and apparatus for joining the ends of spacer strip material which has been fed along the paths and bent, thereby to form the frame.
