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.

Input: Consider Input: Platelets promote liver regeneration through site-specific serotonin release from dense granules, triggering proliferative signaling in hepatocytes. However, the effects of factors derived from platelet α-granules on liver regeneration are unclear, because α-granules contain bioactive molecules with opposing functions. Because α-granule molecules are stored in separate compartments, it has been suggested that platelets selectively release their α-granule content dependent on the environmental stimulus. Therefore, we investigated the pattern of circulating α-granule molecules during liver regeneration in 157 patients undergoing partial hepatectomy. We measured plasma levels of α-granule-derived factors in the liver vein at the end of liver resection, as well as on the first postoperative day. We observed a rapid accumulation of platelets within the liver after induction of liver regeneration. Platelet count and P-selectin (a ubiquitous cargo of α-granules) were not associated with postoperative liver dysfunction. However, low plasma levels of vascular endothelial growth factor (VEGF), but high levels of thrombospondin 1 (TSP-1), predicted liver dysfunction after resection. Patients with an unfavorable postoperative α-granule release profile (high TSP-1/low VEGF) showed substantially worse postoperative clinical outcomes. The unfavorable postoperative α-granule release profile was associated with increased postoperative portal venous pressure and von Willebrand factor antigen levels as a marker for intrahepatic endothelial dysfunction.

Input: Consider Input: To assess the influence of vascular clamping and ischemia time on long-term post-operative renal function following partial nephrectomy (PN) for cancer in a solitary kidney.', 'This is a retrospective study including 259\xa0patients managed by PN between 1979 and 2010 in 13\xa0centers. Clamping use, technique choice (pedicular or parenchymal clamping), ischemia time, and peri-operative data were collected. Pre-operative and last follow-up glomerular filtration rates were compared. A multivariate analysis using a Cox model was performed to assess the impact of ischemia on post-operative chronic renal failure risk.', 'Mean tumor size was 4.0±2.3cm and mean pre-operative glomerular filtration rate was 60.8±18.9mL/min. One hundred and six patients were managed with warm ischemia (40.9%) and 53\xa0patients with cold ischemia (20.5%). Thirty patients (11.6%) have had a chronic kidney disease. In multivariate analysis, neither vascular clamping (P=0.44) nor warm ischemia time (P=0.1) were associated with a pejorative evolution of renal function. Pre-operative glomerular filtration rate (P<0.0001) and blood loss volume (P=0.02) were significant independent predictive factors of long-term renal failure.

Input: Consider Input: Peroxisome proliferator-activated receptor (PPAR)-β/δ is a transcription factor that belongs to the nuclear hormone receptor family. There is little information about the effects of the immediate administration of specific ligands of PPAR-β/δ (GW0742) in animal models of acute ischemic stroke. Using a rat model of middle cerebral ischemia occlusion (MCAO) in\xa0vivo, we have investigated the effect of pretreatment with GW0742 before MCAO.', 'The neuroprotective effect of GW0742 against acute ischemic stroke was evaluated by the neurologic deficit score (NDS), dry-wet weight, and 2,3,5-triphenyltetrazolium chloride staining. The levels of interleukin (IL)-1β, nuclear factor (NF)-κB, and tumor necrosis factor (TNF)-α were detected by an enzyme-linked immunosorbent assay. The expressions of inducible nitric oxide synthase (iNOS), Bax, and Bcl-2 were detected by Western blot. The apoptotic cells were counted by in situ terminal deoxyribonucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick end labeling assay.', 'The pretreatment with GW0742 significantly increased the expression of Bcl-2, and significantly decreased in the volume of infarction, NDS, edema, expressions of IL-1β, NF-κB, TNFα, and Bax, contents of iNOS and the apoptotic cells in infarct cerebral hemisphere compared with rats in the vehicle group at 24\xa0hours after MCAO.
