Cancer vaccines seem straightforward and elegant in theory, yet the effective application of the concept has been largely elusive. Numerous cancer vaccines have shown promise in early phases of development only to have difficulties meeting endpoints in Phase 3 clinical trials. Despite these shortcomings, established pharmaceutical companies have become increasingly interested in cancer immunoth...

Aims. It is well known that the [O ]λ5007 emission line and hard X-ray (2−10 keV) luminosities are good indicators of AGN activities and that the near and mid-infrared emission of AGN originates from re-radiation of dusty clouds heated by the UV/optical radiation from the accretion disk. In this paper we present a study of the near-infrared K-band (2.2 μm) properties for a sample of 65 Seyfe...

Except in the most extreme cases of nuclear activity, either starbursts or AGN, it is difficult to find observationnally a close link between the dynamics and the activity. Theoretically however, the necessary step to fuel the gas to the center, is that gravity torques are created through a non-axisymmetric pattern, either bar and/or spiral, triggered or not by a tidal interaction. We describe ...
