Is organ-related cigarette smoke-induced oxidative stress strain-dependent?
Mouse strains and individual organs display a range of susceptibilities to CS-induced oxidative stress. BALB/c and C57BL/6 strains appear to be the best choices as experimental models for studying CS effects on liver and lung, and C3H and C57BL/6 strains for CS-effects on the brain.
This study has demonstrated that subclinical synovitis, as identified by US, is very common in early PsA and led to the majority of oligoarthritis patients being reclassified as having polyarthritis. Further research is required into the relationship of such subclinical synovitis to structural progression.
