In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Input: Consider Input: Context: To assess the influence of moderate, acute weight loss on on-water rowing performance when aggressive nutritional recovery strategies were used in the two hours between weigh in and racing.', 'Competitive rowers (n = 17) undertook three on-water 1800 m time trials under cool conditions (mean (SD) temperature 8.4 (2.0) degrees C), each separated by 48 hours. No weight limit was imposed for the first time trial--that is, unrestricted body mass (UNR1). However, one of the remaining two trials followed a 4% loss in body mass in the previous 24 hours (WT(-4%)). No weight limit was imposed for the other trial (UNR2). Aggressive nutritional recovery strategies (WT(-4%), 2.3 g/kg carbohydrate, 34 mg/kg Na+, and 28.4 ml/kg fluid; UNR, ad libitum) were used in the first 90 minutes of the two hours between weigh in and performance trials.', 'WT(-4%) had only a small and statistically non-significant effect on the on-water time trial performance (mean 1.0 second, 95% confidence interval (CI) -0.9 to 2.8; p = 0.29) compared with UNR. This was despite a significant decrease in plasma volume at the time of weigh in for WT(-4%) compared with UNR (-9.2%, 95% CI -12.8% to -5.6%; p<0.001).\Question: Does acute weight loss followed by an aggressive nutritional recovery strategy have little impact on on-water rowing performance?

Output: Acute weight loss of up to 4% over 24 hours, when combined with aggressive nutritional recovery strategies, can be undertaken with minimal impact on on-water rowing performance, at least in cool conditions.


Input: Consider Input: Context: This study investigated whether deletion of the alpha1A-adrenoceptor gene influences contractile responses of mouse prostate to noradrenaline. Responses of mouse prostate to noradrenaline are known to be mediated by alpha1L-adrenoceptors, which are thought to be a functional phenotype of alpha1A-adrenoceptor.', 'Prostate tissues from alpha1A-adrenoceptor knockout mice which were homozygous (alpha1A -/-) and heterozygous (alpha1A +/-) for the disrupted alpha1A-adrenoceptor gene, as well as wild-type (alpha1A +/+) littermates were mounted in glass-isolated organ baths. Electrical field stimulation of nerves and exogenous application of noradrenaline were used to investigate the effects of alpha1A-adrenoceptor disruption on prostate contractility.', 'Frequency-response curves to electrical field stimulation (0.5 ms pulse duration, 60 V, 0.1-20 Hz) yielded frequency-dependent contractions. At frequencies of 10 and 20 Hz, prostates from alpha1A -/- mice elicited an approximately 30% decreased response compared with prostates from alpha(1A)+/+ mice. Prazosin (0.3 muM) attenuated responses to electrical field stimulation in prostates from alpha1A +/+ and alpha1A +/- mice but not from alpha1A -/- mice. Increasing concentrations of exogenously administered noradrenaline (10 nM-1 mM) produced mean concentration-response curves in prostates from alpha1A +/+ and alpha1A +/- mice, which were not different. Maximum responses to noradrenaline were decreased by approximately 80% in prostates from alpha1A -/- mice compared with alpha1A +/+ mice. Prazosin attenuated responses to noradrenaline in all genotypes.\Question: Is the alpha1A-adrenoceptor gene required for the alpha1L-adrenoceptor-mediated response in isolated preparations of the mouse prostate?

Output: alpha1L-Adrenoceptor-mediated responses in mouse prostate are abolished in alpha1A -/- mice, demonstrating that the alpha1A-adrenoceptor gene is essential to the manifestation of the prostatic alpha1L-adrenoceptor phenotype. This implies that alpha1L-adrenoceptors are indeed a functional phenotype of alpha1A-adrenoceptor.


Input: Consider Input: Context: This study was to investigate whether the expression of a disintegrin and metalloproteinase-9 (ADAM9) is correlated with the expression of hepatoma-derived growth factor (HDGF) in surgically resected non-small cell lung cancer (NSCLC), to evaluate the significance of HDGF and ADAM9 as novel molecular staging biomarkers, prognostic biomarkers and predictive biomarkers for postoperative adjuvant chemotherapy in surgically resected stage I NSCLC, to provide essential consistence proof to the possible novel pathway of HDGF-ADAM9 pathway.', 'Sixty-three cases of resected stage I NSCLC with mediastinal N2 lymph node dissection were immunohistochemically analyzed for HDGF and ADAM9 protein expression. Multivariate analysis and survival analysis were conducted.', "HDGF and ADAM9 were observed highly expressed in NSCLC compared with normal control lung tissues (P < 0.05). HDGF high expression cases showed significantly lower survival rate (55.6 vs. 84.7 %, P = 0.009). HDGF high expression was an independent factor of shortened survival time in resected stage I NSCLC (P = 0.015). ADAM9 high expression cases showed significantly lower survival rate (56.9 vs. 88.7 %, P = 0.015). ADAM9 high expression was an independent factor of shortened survival time in resected stage I NSCLC (P = 0.021). Pearson's correlation analysis revealed that ADAM9 expression was correlated positively and significantly with HDGF expression in 63 cases of stage I NSCLC (r = 0.547, P = 0.000).\Question: Are hDGF and ADAM9 novel molecular staging biomarkers , prognostic biomarkers and predictive biomarkers for adjuvant chemotherapy in surgically resected stage I non-small cell lung cancer?


Output: These results clearly demonstrate that ADAM9 high expression is correlated positively and significantly with HDGF high expression, which provides essential evidence for the novel HDGF-ADAM9 pathway, through which HDGF promotes invasion and metastasis of NSCLC cells; HDGF and ADAM9 are novel molecular staging biomarkers, prognostic biomarkers, which might become useful predictive biomarkers for the selection of postoperative adjuvant chemotherapy treatment in surgically resected stage I NSCLC.
