Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Input: Consider Input: Tinnitus can adversely affect patients' quality of life. Transcutaneous electrical nerve stimulation (TENS) may be effective in the management of tinnitus. No study has investigated the efficacy of TENS for the management of tinnitus by means of quality of life measures. In this study, we evaluated the efficacy of TENS for the management of tinnitus symptoms by using the visual analogue scale (VAS), tinnitus handicap inventory test, Nottingham health profile (NHP) and short form-36 (SF-36) questionnaires.", 'Twenty-two patients were included in this study (male/female, 16/6; mean age, 48.04 +/- 15.57 years). Nine patients had unilateral and 13 patients had bilateral tinnitus.', 'After TENS, improvement measured by VAS was only marginally significant (p = 0.059). However, after TENS, there were statistically significant improvements regarding tinnitus severity scores, tinnitus handicap inventory scores, NHP fatigue, social isolation and emotional problems scores, and many parameters measured by the SF-36 (physical functioning, general health, vitality, social functioning, role limitations due to emotional problems, and mental health)(p < 0.05).

Output: Does treatment of tinnitus with transcutaneous electrical nerve stimulation improve patients ' quality of life?


Input: Consider Input: Construction of electrochemical impedance sensors by the self-assembly technique has become a promising strategy for the 'label-free' detection of protein-ligand interactions. However, previous impedance sensors are devoid of an inherent electrochemical signal, which limits the standardization of the sensors for protein recognition in a reproducible manner.", "We designed and synthesized an anthraquinonyl glycoside (AG) where the anthraquinone (AQ) moiety can bind to the surface of a graphene-based working electrode while the glycoside serving as a ligand for lectin. By measuring the inherent voltammetric signal of AQ, the glycosides decorated on the working electrode could be simply quantified to obtain electrodes with a unified signal window. Subsequently, impedance analysis showed that the 'standardized' electrodes gave a reproducible electrochemical response to a selective lectin with no signal variation in the presence of unselective proteins.

Output: Does anthraquinonyl glycoside facilitate the standardization of graphene electrodes for the impedance detection of lectins?


Input: Consider Input: To assess the activity of mTOR and downstream effector proteins in the mTOR pathway after treatment with a dual mTOR complex 1 and 2 (mTORC1/2) inhibitor (PP242) compared with that of mTOR complex 1 (mTORC1) inhibitor (rapamycin) using a xenograft tumor model.', 'Pheochromocytoma PC12 cell were xenografted into nude mice. Animals were treated with PP242 and rapamycin. Mean tumor volume was compared across groups. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling staining was used to detect apoptosis. Immunoblot analysis was performed to assess mTORC1/2 activity using p-Akt, p-S6, and p-4E-BP1. The expression of the antiapoptotic protein Bcl-2, pro-apoptotic protein Bax, and the mediator of angiogenesis vascular endothelial growth factor were also investigated.', 'The mean tumor volume of PP242 was significantly lower than in other groups. The terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling results showed that PP242 markedly increased cell apoptosis compared with other groups. Immunoblot analysis of tumor lysates treated with PP242 demonstrated inhibition of activated p-Akt. We also observed that only PP242, but not rapamycin, significantly reduced Bcl-2 expression and markedly increased Bax expression. Rapamycin decreased vascular endothelial growth factor expression, but not nearly as striking as seen in the PP242 group.


Output: Does the dual mTORC1 and mTORC2 inhibitor PP242 show strong antitumor activity in a pheochromocytoma PC12 cell tumor model?
