Q: Question: Do workers of a drywood termite work?
Answer: Thus, in contrast to general perception where termite workers are considered equivalent to workers in Hymenoptera, the 'large immatures' of C. secundus did not behave as workers that help in raising younger siblings. This apparently is not necessary as the colony lives inside its food. These results, which are likely to be typical for wood-dwelling termites, open the possibility that large complex group living can evolve without altruistic helping and that costly altruistic helping by workers in termites evolved only as a second step.

Q: Question: Is three-dimensional speckle strain echocardiography more accurate and efficient than 2D strain in the evaluation of left ventricular function?
Answer: Three-dimensional STE is feasible and reproducible in the estimation of LV function, requires substantially less time than 2DSTE and is a more feasible technique for LV function assessment in clinical practice.

A: yes

Q: Question: Do rabbit nucleus pulposus cells facilitate differentiation of adipose-derived stem cells into nucleus pulposus-like cells?
Answer: In some condition, ADSCs have the potency to differentiate toward nucleus pulposus-like cells. ADSCs are better seed cells for tissue engineering of artificial nucleus pulposus.

A:
yes
