“…The host morphology of PKS1502+036 is well fit with a Sersic index n = 3.5, indicative of an elliptical host galaxy ( [34]), and there is some evidence for a galaxy interaction. Imaging of the mildly radioloud IRAS20181-2244 has revealed an interacting or merging pair of galaxies with a pronounced tidal tail; the host galaxy is well described by a disc morphology ( [14]).…”

Radio-loud Narrow-line Seyfert 1 (NLS1) galaxies are unique probes of the formation of powerful radio jets at extreme (near-Eddington) accretion rates and low black hole masses, in a regime very different from classical blazars and, therefore, not probed before. Further, strong thermal and nonthermal components simultaneously present in their spectral energy distributions (SEDs), shed new light on the jet-disk connection at much shorter timescales, given their low SMBH masses. While NLS1 galaxies have been studied thoroughly at optical and X-ray energies for decades, the populations of radio-loud, and γ-ray emitting NLS1 galaxies have only emerged more recently. This contribution provides a short review of the multi-wavelength properties of this intriguing class of Active Galactic Nuclei (AGN), including X-ray variability and emission mechanisms, γ-ray discoveries, SEDs, star formation activity, host galaxy morphologies, different methods of black hole mass estimation, (unexpected) FeII properties, and high-velocity large-scale outflows possibly driven by the radio jet and with a surprisingly pronounced ionization stratification.Revisiting narrow-line Seyfert 1 galaxies and their place in the Universe Radio-loud NLS1 galaxies S. Komossa this then implies accretion at or near the Eddington limit (Fig. 1). NLS1 galaxies are, therefore, rapidly growing their supermassive black holes (SMBHs), and may represent young or re-juvenated AGN ([99]). In the Eigenvector (EV) analysis of [18], the Eddington ratio L bol /L Edd drives the first eigenvector EV1, while accretion rate drives EV2.While NLS1 galaxies are on average more radio-quiet than broad-line AGN, a fraction of NLS1s are beamed and radio-loud, are highly variable at radio frequencies, and are detected at γ-rays. This contribution provides a review of the multi-wavelength properties of this remarkable new class of radio-loud, jet-emitting AGN.

“…Further investigations demonstrated that agents blocking de novo RNA and protein synthesis were instead able to prevent IFN-y-enhancement of neutrophil respiratory burst capability [ 17,191. These latter data indicated that cytokine-induced expression of genes encoding NADPH oxidase components might be relevant for the phenomenon and prompted us to verify our hypothesis [ZO].…”

“…6 Cette aberration révèle toute l'ambivalence du projet de Lichtenstein : dénoncer l'obscurantisme de l'évangélisme moderne et mettre en scène des accouplements morbides dont on devine assez facilement l'issue. Ce qui fera dire à Jean-Baptiste Thoret que Teeth, c'est un peu le serpent qui « finit par se mordre la queue » 3 ... 7 La contradiction est au coeur même de la SF occidentale. Selon Alexandre Hougron, celleci est intrinsèquement liée au « mythe de la pureté et de l'excellence » qui resurgit dans le monde occidental de la fin du 19 e siècle.…”
