Question: Question: Is early systemic sclerosis : serum profiling of factors involved in endothelial , T-cell , and fibroblast interplay marked by elevated interleukin-33 levels?
Answer: Our study suggests that an endothelial, T-cell and fibroblast activation can be present in patients with early SSc and it is associated with a distinct profile of circulating factors involved in the cross-talk of these cells. The marked increase of IL-33 in early SSc patients suggests new routes of investigation of cell-cell dynamics in target tissues predating overt disease manifestations, thus opening to new therapeutic approaches.

Answer: yes


Question: Question: Does nitric oxide synthase inhibition improve renal function in cirrhotic patients with ascites?
Answer: Despite a partial correction of the hyperdynamic circulation, inhibition of NO synthesis does not improve sodium and water excretion in decompensated cirrhosis, probably because of an accompanying decrease in renal plasma flow. Intrarenal NO synthesis may be important for maintaining intrarenal hemodynamics in decompensated cirrhotic patients.

Answer:
no
