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]: To fully understand the cytotoxicity of after-degradation QDs, we synthesized CdS QDs and investigated its toxicity mechanism.', 'Biomimetic method was proposed to synthesize cadmium sulfide (CdS) QDs. Thereafter MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide) assay was conducted to evaluate their cytotoxicity. To investigate the toxicity mechanism, we subsequently conducted intracellular reactive oxygen species (ROS) measurement with DCFH-DA, glutathione (GSH) measurement with DTNB, and cellular cadmium assay using atomic absorption spectrometer. Microsized CdS were simultaneously tested as a comparison.', "MTT assay results indicated that CdS QDs are more toxic than microsized CdS especially at concentrations below 40 microg/ml. While microsized CdS did not trigger ROS elevation, CdS QDs increase ROS by 20-30% over control levels. However, they both deplete cellular GSH significantly at the medium concentration of 20 microg/ml. In the presence of NAC, cells are partially protected from CdS QDs, but not from microsized particles. Additionally, nearly 20% of cadmium was released from CdS nanoparticles within 24h, which also accounts for QDs' toxicity.

[Q]: 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.

[Q]: To study the influence of the severity of depression on the eating disorder's inventory (EDI) scores in anorexia nervosa (AN) patients.", "We compared by variance analysis the EDI scores from three groups of AN patients: 55 patients having a major depression (as assessed by a Beck's depression inventory (BDI) >/= 16); 77 patients having a less severe depression (BDI < 16); 32 patients with mild or non-existent depression (BDI </= 7) and the EDI scores from a control group of 29 French healthy young women.", 'Higher EDI scores were elicited in the more severely depressed AN patients than in the less- or non-depressed AN patients (P < 0.01). In non-depressed AN patients, none of the scores was different from those of the control group. This was particularly true for the scores "Slimness wish", "bulimia", "body image dissatisfaction", "perfectionism" and "fear of maturity". The non-depressed restrictive AN patients had no score which differ from healthy controls.
