Abstract: The present invention relates generally to the fields of immunology and vaccine technology. More specifically, the present invention relates to methods for freeze-drying biological preparations, including peptides, antigens, antibodies, and especially, cells. Importantly, the disclosed methods preserve the viability, infectivity and immunogenicity of cells from the Apicomplexa phylum, the Sarcocystidae family, and in particular, cells from the Toxoplasma genus.

Abstract: A content reception device includes a station selection switch. The station selection switch is operated to select a desired broadcast station from a plurality of broadcast stations that are broadcasting by streaming through a plurality of channels by shifting times little by little. When the station selection switch is operated to select a desired broadcast station from a plurality of broadcast stations, a channel is selected from a plurality of channels allocated to the currently-selected broadcast station according to the number of times a first selection switch and a second selection switch are operated. This allows the user to go back the time of the streaming broadcast and reverse the progress of the content in a pseudo mode or to advance the time and fast-forward the content in a pseudo mode.
