Abstract: The present disclosure relates to antibodies having the ability to bind to the immune checkpoint protein programmed death-1 (PD-1), such as human PD-1, or nucleic acids encoding such antibodies, wherein the antibodies comprise modifications in the Fc region eliminating or reducing a Fc-mediated effector function of the antibodies. The present disclosure also relates to compositions or kits comprising said antibodies or nucleic acids, as well as to the use of these antibodies or nucleic acids or compositions in the field of medicine, preferably in the field of immunotherapy, e.g., for the treatment of cancers. The present invention further relates to methods for inducing an immune response in a subject comprising providing to the subject an antibody of the present disclosure or one or more nucleic acids encoding such an antibody, or a composition comprising said antibody or nucleic acids.

Abstract: One example method for controlling presentations in video conferences includes displaying, by a video conference application executing on a first client device, a first slide of a plurality of slides in a slide presentation as part of a visual display of a video conference on the first client device, receiving, by the video conference application executing on the first client device from the video conference application executing on a second client device, a command to display a second slide, wherein the command is issued by a first user of a plurality of users of the video conferencing application authorized to control the slide presentation; and displaying, by the video conference application executing on the first client, the second slide in response to receiving the command.

Abstract: A fire escape chamber includes a hermetically sealable outer cage with outer side wall elements, with an outer floor element and with an outer ceiling element. Fire protection insulation layers are provided on the inner sides of the outer elements with some fastened by pin elements, which protrude from the outer side wall elements and from the outer ceiling element into the respective fire protection insulation layers. An inner cage has inner side wall elements, an inner ceiling element and an inner floor element. The inner floor element is mounted in a supporting manner on the fire protection insulation layer of the outer floor element. The inner side wall elements and the inner ceiling element are formed by a plurality of support structure elements, on the inner sides of which panels are, in turn, fastened. The support structure elements are located at spaced locations from the pin elements.
