Abstract: The present invention relates to targeting peptides and more specifically peptides that target heart and various tumors as well as to their use for targeting. The present invention also provides a composition comprising at least one therapeutic agent and at least one peptide of the invention or, alternatively, a nucleic acid molecule encoding such a peptide as well as its use for the preparation of a drug intended for gene transfer. The present invention also provides an adenoviral vector comprising at least one peptide of the invention exposed at the surface of the viral particle and its use for targeting tumor cells as well as a method for treating or preventing a cancer or a tumor comprising administering said adenoviral vector.

Abstract: The invention concerns a method for separating, by impaction, living particles and particles capable of being revived of a gas or a gas mixture under pressure, characterised in that it comprises a step (a) which consists in accelerating in a stage and along an axis (x) a single gas or gas mixture stream in a confined volume (V), to reach a speed not less than the speed of sound; a step (b) which consists in sudden deceleration of said single stream derived from step (a) in said volume, along substantially the same axis (x), at atmospheric pressure; a step (c) which consists in changing the direction of the gas or gas mixture flow at the output of the volume (V), which on average becomes radial; and a step (d) which consists in trapping said particles separated from the flow during step (c), on a target. In another embodiment, the method further comprises a step (e) which consists in counting the particles trapped during step (d).
