Janus kinase 2 inhibition by pacritinib as potential therapeutic target for liver fibrosis

open access: yesHepatology, EarlyView., 2022
Diagram of the activation of the profibrotic and procontractile Janus kinase 2 (JAK2)/Ras homolog family member A/Rho‐kinase pathway and the inhibition of phosphorylated JAK2 by pacritinib to inhibit hepatic stellate cell activity. Abstract Background and Aims Janus kinase 2 (JAK2) signaling is increased in human and experimental liver fibrosis with ...

Merger driven explosive evolution of distant galaxies (minor mergers) [PDF]

open access: yesAstrophysical Bulletin, 2013
We derived solutions for the Smoluchowski kinetic equation for the mass function of galaxies, which describes mergers in differential approximation, where mergers with low-mass galaxies are the dominant factor. The evolution of the initial distribution is analyzed as well as the influence of the source represented by galaxies (halos) that separate from

Star Formation Histories of Nearby Elliptical Galaxies. II. Merger Remnant Sample [PDF]

open access: yes, 2006
This work presents high $S/N$ spectroscopic observations of a sample of six suspected merger remnants, selected primarily on the basis of H{\sc i} tidal debris detections.

Mergers and galaxy assembly [PDF]

open access: yesThe 9th astrophysics conference: After the dark ages, when galaxies were young (the Universe at 2<Z<5), 1999
Theoretical considerations and observational data support the idea that mergers were more frequent in the past. At redshifts z = 2 to 5, violent interactions and mergers may be implicated by observations of Lyman-break galaxies, sub-mm starbursts, and active galactic nuclei.

Decoding Galactic Merger Histories

open access: yesGalaxies, 2017
Galaxy mergers are expected to influence galaxy properties, yet measurements of individual merger histories are lacking. Models predict that merger histories can be measured using stellar halos and that these halos can be quantified using observations of

Merger relics of cluster galaxies [PDF]

open access: yes, 2013
Context. Sheen and collaborators recently found that a surprisingly large portion (38%) of massive early-type galaxies in heavy clusters show strong merger-related disturbed features.

The Chandra view of galaxy mergers [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2007
From a Chandra survey of nine interacting galaxy systems the evolution of X-ray emission during the merger process has been investigated. It is found that the X-ray luminosity peaks ~300 Myr before nuclear coalescence, and then dips, even though we know that rapid and increasing activity is still taking place at this time.
