Given a passage with a context and an answer, 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.

Q: Context: Is weight-training exercise intervention harmful to women with or at risk of breast cancer-related lymphoedema?', 'Systematic review with meta-analysis of randomised trials.', 'Women with or at risk of breast cancer-related lymphoedema.', 'Progressive weight-training exercise.', 'The primary outcomes were severity (volume difference) and incidence of arm lymphoedema. Secondary outcomes included muscle strength of the upper and lower limbs, quality of life and body mass index.', 'Eleven studies from eight trials involving 1091 women were included. Weight-training exercise of low to moderate intensity with relatively slow progression significantly improved the upper limb strength (SMD 0.93, 95% CI 0.73 to 1.12) and lower limb strength (SMD 0.75, 95% CI 0.47 to 1.04) without increasing the arm volume (SMD -0.09, 95% CI -0.23 to 0.05) or incidence of breast cancer-related lymphoedema (RR 0.77, 95% CI 0.52 to 1.15). No significant effects were noted for body mass index (SMD -0.10, 95% -0.31 to 0.11). Some aspects of quality of life may improve with weight training. PARTICIPANTS in all trials used pressure garments and received supervision; no trials used high-intensity weight training.
Answer: Weight training appears to be safe and beneficial in improving limb strength and physical components of quality of life in women with or at risk of lymphoedema. Pressure garments, supervision and limiting the intensity of the weight training may each be important, but this could not be confirmed with this review.

Q: Context: The aim of this study was to compare the efficacy of surgery for spontaneous intracerebral hemorrhage with that of medical treatment, based on data from the Japan Stroke Registry Study.', 'From 1999 to 2001, 1010 patients with spontaneous intracerebral hemorrhage were registered in the Japan Standard Stroke Registry Study from 45 stroke center hospitals in Japan. The National Institutes of Health Stroke Scale (NIHSS), Japan Stroke Scale (JSS), and modified Rankin Scale scores were used to compare severity and improvement in patients given surgical and medical treatment.
Answer: Surgically treated patients, especially those with cerebellar hemorrhage, had significantly greater improvement in NIHSS or JSS score compared with medically treated patients. Our findings indicated that the patients who underwent surgery appeared to have better outcomes. But, because the study was not randomized, this observation cannot be interpreted as indicating that surgery is advantageous.

A: Does surgery for spontaneous intracerebral hemorrhage have greater remedial value than conservative therapy?

Q: Context: Amino acid substitutions within the AdeRS two-component system are believed to result in overexpression of the AdeABC efflux pump and extensive resistance to antibiotics in clinical Acinetobacter baumannii isolates. However, the exact amino acid substitutions in AdeRS that cause overexpression of the AdeABC efflux pump remain unclear. We elucidated the role of amino acid substitutions in AdeRS by a complementation assay in an adeRS knockout strain of A. baumannii.', 'Five types of adeRS operon from tigecycline-resistant XDR A. baumannii (XDRAB) were cloned and introduced into the adeRS knockout strain to reverse its tigecycline susceptibility.', 'Through shuffling gene segments among those five adeRS operons and performing site-directed mutagenesis, we found that the specific amino acid substitution Gly186Val in AdeS is crucial for reducing tigecycline susceptibility of A. baumannii.
Answer: Our result demonstrates that a critical amino acid substitution in AdeS alters the AdeABC efflux pump-mediated tigecycline resistance of A. baumannii.

A:
Does single amino acid substitution Gly186Val in AdeS restore tigecycline susceptibility of Acinetobacter baumannii?
