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 ...

The effect of structure and star formation on the gas content of nearby galaxies [PDF]

open access: yes, 2015
We revisit the main HI-to-stellar mass ratio (gas fraction) scaling relations, taking advantage of the HI spectral stacking technique to understand the dependence of gas content on the structural and star formation properties of nearby galaxies.

THE IMPACT OF STELLAR FEEDBACK ON THE STRUCTURE, SIZE, AND MORPHOLOGY OF GALAXIES IN MILKY-WAY-SIZED DARK MATTER HALOS [PDF]

open access: yes, 2015
We use cosmological zoom-in simulations of galaxy formation in a Milky-Way-sized halo started from identical initial conditions to investigate the evolution of galaxy sizes, baryon fractions, morphologies, and angular momenta in runs with different ...

Catalogue of the morphological features in the Spitzer Survey of Stellar Structure in Galaxies (S4G) [PDF]

open access: yes, 2015
Context. A catalogue of the features for the complete Spitzer Survey of Stellar Structure in Galaxies (S4G), including 2352 nearby galaxies, is presented.

The large-scale structure of the Universe [PDF]

open access: yesNature, 2006
Research over the past 25 years has led to the view that the rich tapestry of present-day cosmic structure arose during the first instants of creation, where weak ripples were imposed on the otherwise uniform and rapidly expanding primordial soup.

The dependence of star formation history and internal structure on stellar mass for 105 low‐redshift galaxies [PDF]

open access: yes, 2002
We study the relations between stellar mass, star formation history, size and internal structure for a complete sample of 122 808 galaxies drawn from the Sloan Digital Sky Survey.

THE SPITZER SURVEY OF STELLAR STRUCTURE IN GALAXIES (S4G): PRECISE STELLAR MASS DISTRIBUTIONS FROM AUTOMATED DUST CORRECTION AT 3.6 μm [PDF]

open access: yes, 2014
The mid-infrared is an optimal window to trace stellar mass in nearby galaxies and the 3.6 &mgr; m ?> IRAC band has been exploited to this effect, but such mass estimates can be biased by dust emission.

Metal-line absorption around z ≈ 2.4 star-forming galaxies in the Keck Baryonic Structure Survey [PDF]

open access: yes, 2014
We study metal absorption around 854 z ≈ 2.4 star-forming galaxies taken from the Keck Baryonic Structure Survey. The galaxies examined in this work lie in the fields of 15 hyperluminous background quasi-stellar objects, with galaxy impact parameters ...

The Structure of cold dark matter halos [PDF]

open access: yes, 1995
High resolution N-body simulations show that the density profiles of dark matter halos formed in the standard CDM cosmogony can be fit accurately by scaling a simple “universal” profile.

The environmental dependence of the relations between stellar mass, structure, star formation and nuclear activity in galaxies [PDF]

open access: yes, 2004
We use a complete sample of galaxies drawn from the Sloan Digital Sky Survey to study how structure, star formation and nuclear activity depend on local density and on stellar mass.
