Abstract: A chair includes a base structure and a seat which is movably secured to the base structure. Connected to the seat is a backrest for swinging in a virtually wall-avoiding manner. A footrest is movable between a stowed position when not being used and an extended position when in use, wherein the footrest is disposed in the stowed position below the seat in approximate parallel relationship thereto and has a seat-distal surface provided with a padding. The footrest is connected to the seat by a swivel fitting which is constructed such that a movement of the backrest causes a movement of the footrest.

Abstract: Methods are disclosed whereby protease activity is directly linked to delivery of a transferable label to a target cell which expresses a protease, via fusion of viral display packages comprising the transferable label with the target cell. The methods can be used, inter alia, to identify proteases, including previously undiscovered proteases or variants of known proteases which may have altered substrate specificity.
