Ex Input:
Question: Does short-term enteral glutamine enhance protein accretion in burned children : a stable isotope study?
Answer: Rapid protein accretion does not occur with short-term enteral glutamine supplementation. Several days of glutamine supplementation may be required to restore plasma glutamine levels and stimulate protein synthesis.

Ex Output:
no


Ex Input:
Question: Does leukocyte concentration and composition in platelet-rich plasma ( PRP ) influence the growth factor and protease concentrations?
Answer: These findings demonstrate that leukocytes strongly influence the quality of PRPs. Therefore, modifying the PRP preparation method according to the pathology is essential to achieve better clinical results with PRP therapy.

Ex Output:
yes


Ex Input:
Question: Does the mu opioid receptor activation affect ischemia-induced agonal currents in rat spinal ventral horn?
Answer: Activation of MORs does not influence ongoing ischemia-induced neuronal death. Our findings indicate that MOR agonist administration should be suitable as an anesthetic during aortic surgery.

Ex Output:

no
