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.

[EX Q]: 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.

[EX Q]: Zuo-Jin-Wan (ZJW), a traditional Chinese medicine formula, has been identified to be effective against drug resistance in cancer. In the present study, we investigated the effect of ZJW on acquired oxaliplatin-resistant and the PI3K/Akt/NF-κB pathway in vitro.', 'We tested the dose-response relationship of ZJW on reversing drug-resistance by CCK-8 assay and flow cytometry analysis in vitro. The protein expression of P-gp, MRP-2, LRP, and ABCB1 mRNA expression level were evaluated by Western blot and quantitative RT-PCR. The activities of PI3K/Akt/NF-κB pathway were also examined with or without ZJW, including Akt, IκB, p65 and their phosphorylation expression.', 'We found that ZJW significantly enhanced the sensitivity of chemotherapeutic drugs and increased oxaliplatin (L-OHP)-induced cell apoptosis in a time- and dose-dependent manner. Moreover, both ZJW and a PI3K specific inhibitor (LY294002) suppressed phosphorylation of Akt (Ser473) and NF-κB, which is necessary in the activation of the PI3K/Akt/NF-κB pathway. The effect of ZJW in reversing drug-resistance and suppressing phosphorylation of Akt (Ser473) and NF-κB were weakened after treatment with a PI3K/Akt activator in HCT116/L-OHP cells.

[EX Q]: Osteoarthritis (OA) is associated with a gradual reduction in the interstitial osmotic pressure within articular cartilage. The aim of this study was to compare the effects of sudden and gradual hypo-osmotic challenge on chondrocyte morphology and biomechanics.', 'Bovine articular chondrocytes were exposed to a reduction in extracellular osmolality from 327 to 153 mOsmol/kg applied either suddenly (<5 s) or gradually (over 180 min). Temporal changes in cell diameter and the existence of regulatory volume decrease (RVD) were quantified along with changes in cortical actin and chromatin condensation. The cellular viscoelastic mechanical properties were determined by micropipette aspiration.', 'In response to a sudden hypo-osmotic stress, 66% of chondrocytes exhibited an increase in diameter followed by RVD, whilst 25% showed no RVD. By contrast, cells exposed to gradual hypo-osmotic stress exhibited reduced cell swelling without subsequent RVD. There was an increase in the equilibrium modulus for cells exposed to sudden hypo-osmotic stress. However, gradual hypo-osmotic challenge had no effect on cell mechanical properties. This cell stiffening response to sudden hypo-osmotic challenge was abolished when actin organization was disrupted with cytochalasin D or RVD inhibited with REV5901. Both sudden and gradual hypo-osmotic challenge reduced cortical F-actin distribution and caused chromatin decondensation.
