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.

[EX Q]: Context: The ability of CD8(+) T-cells to induce prostate inflammation was examined using a prostate ovalbumin expressing transgenic mouse (POET) and/or adoptive transfer of T-cell receptor (TCR) transgenic T-cells (OT-I) that specifically recognize ovalbumin. Localization of inflammatory cells to prostate tissue was examined following T-cell activation via endogenous prostatic antigen, recombinant type 5 adenovirus carrying the gene coding ovalbumin (Ad5-mOVA), or adoptive transfer of in vitro antigen stimulated OT-I cells.', 'Ovalbumin specific OT-I cells were activated by autologous prostate antigen and trafficked to the prostate, but did not induce inflammation unless present in overwhelming numbers ( approximately 65% of CD8(+) T-cells). Activation of antigen specific CD8(+) T-cells in vitro (peptide pulsed antigen presenting cells) or in vivo (Ad5-mOVA) induced transitory prostate inflammation, without induction of prostate pathology, regardless of CD4(+) T-cell availability. Inflammation also was observed in OT-I x POET mice but again, pathological effects were not observed.
Answer: T lymphocytes specific for a prostate antigen are capable of inducing inflammatory infiltration of prostatic tissue rapidly following activation, but do not produce pathological prostate injury.

[EX Q]: Context: Recently, the Arg389Gly beta1-adrenoceptor (beta1AR) gene polymorphism has been detected. The Arg variant exhibited increased responsiveness to agonist-induced stimulation in vitro. Functional studies in isolated human atrial muscle strips and in-vivo studies revealed contradictory results regarding the functional relevance of this polymorphism. We sought to characterize the functional consequences of the Arg389Gly beta1-AR polymorphism in 30 consecutive healthy male volunteers in vivo.', 'beta1-AR genotype was determined by PCR and restriction analysis, which was confirmed by DNA sequencing. We compared heart rate, blood pressure, and contractile response of the various genotype carriers with a modified dobutamine stress echocardiography protocol.', 'Subjects homozygous for the Arg389 beta1AR showed a significantly higher increase in fractional shortening upon cumulative doses of dobutamine as compared to subjects carrying one or two copies of the Gly389 allele. A statistically significant difference was observed at a dobutamine dose of 10 microg/kg/min (46.5 +/- 1.3 vs. 41.8 +/- 1.0 %; P = 0.023) and was maximal at 40 microg/kg/min (61.9 +/- 1.4 vs. 52.8 +/- 1.6; P = 0.001). As a result, the systolic blood pressure response to dobutamine was significantly enhanced in individuals homozygous for the Arg389 allele, whereas the effect on heart rate did not differ between the two groups. Normalization for changing afterload conditions by calculating the pressure-dimension ratio revealed similar effects, indicating that the beta1AR-mediated effects are mainly a result of increased myocardial inotropy.
Answer: These data indicate that the Arg389Gly beta1AR polymorphism is functionally relevant in vivo and determines contractile responsiveness to catecholamines in humans.
[EX A]: Does the Arg389Gly beta1-adrenoceptor gene polymorphism determine contractile response to catecholamines?

[EX 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.
