Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

[Q]: 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.
[A]: yes


[Q]: Question: Does gPR39 activate proliferation and differentiation of porcine intramuscular preadipocytes through targeting the PI3K/AKT cell signaling pathway?
Answer: It indicated that GPR39 was a transducer of Zn(2+), and enhanced proliferation and differentiation of porcine intramuscular preadipocytes through activation of the PI3K/Akt signaling pathway.
[A]: yes


[Q]: Question: Does tetramethylpyrazine protect lymphocytes from radiation-induced apoptosis through nuclear factor-κB?
Answer: The results suggest that TMP had a radioprotective effect through the NF-κB pathway to inhibit apoptosis, and it may be an effective candidate for treating radiation diseases associated with cell apoptosis.
[A]:
yes
