Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

Example Input: To determine whether sympathetic nerves regulate expression of known angiogenic growth factors.', 'Surgical sympathectomy (SNX) was used to remove sympathetic innervation to the eye. Real-time PCR was used to measure steady state mRNA expression of VEGF, VEGFR-2, angiopoietin-1, and Tie2. Western blot analysis was performed to assess protein expression. Blood-retinal barrier (BRB) permeability surface area product (PS) was measured using enhanced MRI on a separate group of control and SNX rats.', 'mRNA of both VEGF and VEGFR-2 decreased significantly at 6 weeks after SNX. VEGF protein expression also decreased significantly. VEGFR-2 protein was unchanged. Both angiopoietin-1 and Tie2 mRNA expression increased significantly after SNX. Immunoblot analysis showed that angiopoietin-1 protein expression coincided with its mRNA expression. Tie2 protein expression was unaffected. Sympathetic denervation did not significantly increase BRB PS.

Example Input: Golgi phosphoprotein 3 (GOLPH3) has been reported to be involved in the development of several human cancers. The present study was conducted to investigate the expression of GOLPH3 and its prognostic significance in renal cell carcinoma (RCC). Meanwhile, the function of GOLPH3 in human RCC was further investigated in cell culture models.', 'Expression of GOLPH3 was examined in 43 fresh RCC tissues and paired adjacent normal renal tissues by real-time quantitative PCR and western blotting. Immunohistochemistry for GOLPH3 was performed on additional 218 RCC tissues. The clinical significance of GOLPH3 expression was analysed. Downregulation of GOLPH3 was performed using small-interfering RNA (siRNA) in Caki-1 and 786-O cells with high abundance of GOLPH3, and the effects of GOLPH3 silencing on cell proliferation, migration, invasion in vitro, and tumour growth in vivo were evaluated.', "Expression of GOLPH3 was upregulated in the majority of the RCC clinical tissue specimens at both mRNA and protein levels. Clinicopathological analysis showed that GOLPH3 expression was significantly correlated with T stage (P<0.001), lymph-node status (P=0.003), distant metastasis (P<0.001), tumour-node-metastasis (TNM) stage (P<0.001), and Fuhman grade (P=0.001). Expression of GOLPH3 was inversely correlated with both overall and recurrence-free survival of RCC patients. Multivariate analysis showed that GOLPH3 expression was an independent prognostic indicator for patient's survival. Knockdown of the GOLPH3 expression reduced cell proliferation, anchorage-independent growth, migration, invasion, and tumour growth in xenograft model mice.

Example Input: To measure the clearance intraperitoneal mitomycin C and doxorubicin in patients having peritonectomy and analyze the impact of the extent of peritoneal resection on pharmacokinetics.', 'A group of 15 patients with peritoneal carcinomatosis were submitted to cytoreductive surgery and heated intraperitoneal chemotherapy. Ten patients received mitomycin C and five, doxorubicin. Six patients underwent total parietal peritonectomy and nine had less-extensive peritonectomy. Pharmacokinetics were determined by sampling peritoneal fluid and blood. Drug concentrations over time, area under the curve ratios and the amount of drug recovered from the peritoneal cavity were calculated and compared between the groups.', 'The concentrations of mitomycin C over time in the peritoneal fluid and plasma were similar in five patients with total parietal peritonectomy as compared to five patients with less-extensive peritonectomy ( P=0.5350 and 0.6991; Mann-Whitney test). Mitomycin C area under the curve ratio in total peritonectomy patients was 20.5 and 25.7 in patients with less-extensive peritonectomy. The difference in total amount of drug recovered from the peritoneal cavity was not significant (30.6+/-6.188% versus 22.6+/-3.84%, P=0.095). In the studies with doxorubicin, one patient underwent total parietal peritonectomy with similar pharmacokinetics to four patients submitted to partial peritonectomy.
