The present invention relates to combined preparation containing as active substance the following individual components, in the form of a kit-of-parts: monocyte derived cells, particularly cytotoxic macrophages, chemotherapy or immunotherapy drugs, for the simultaneous, separate or sequential use, for the treatment of cancer or infectious diseases. The conferencing device may be a speakerphone with a speak up indicator. A synthesized multiview video is generated from the acquired multiview videos for a virtual camera. The body may have more than one thread count or more than one geometry. The LDH-containing magnetic cores were prepared in a colloid mill reactor by a rapid nucleation method, and subsequently calcined to give a solid base mixed oxides coated on magnetic cores.
