instruction:
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.
question:
Gap junction channels provide for direct electrical coupling between cells, and play an important role in homeostasis and electrical coupling. One of the proteins that form gap junctions, Connexin40 (Cx40), shows restricted expression in the body, and is found in blood vessels and in the atrium and conduction system of the heart. We have investigated whether gap junction channels formed of Cx40 are modulated by protein-kinase-A-mediated phosphorylation.', 'A communication-deficient human hepatoma cell line (SKHep1) was stably transfected with human Cx40 cDNA and the properties of Cx40 gap junctions channels and their modulation by cAMP were analyzed using immunocytochemistry, Western blotting, dual patch clamp, and dye coupling.', 'Administration of 1 mM 8-Br-cAMP resulted in a mobility shift of Cx40 protein on western blot and increased macroscopic gap junctional conductance between cell pairs by 46.2 +/- 12.0% (mean +/- S.E.M., n = 8). Under control conditions, single channel experiments revealed three single channel conductances around 30, 80 and 120 pS. When cAMP was added, channel conductances of 46 and 120 pS were observed. In monolayers, cAMP also increased the permeability of Cx40 gap junction channels for Lucifer Yellow by 58%.

question:
To determine the prognostic role of co-morbidity in medically inoperable early-stage non-small cell lung cancer (NSCLC) treated with stereotactic body radiotherapy (SBRT).', "Between 2000 and 2007, 88 consecutive early-stage medically inoperable NSCLC patients were treated by linac-based SBRT. The dose was either 45 Gy or 67.5 Gy in three fractions prescribed to the isocenter. Baseline co-morbidities were retrospectively retrieved by consultation of a formal electronic registry of diagnoses as well as patients' charts. The age-adjusted Charlson Co-morbidity Index (CCI) was scored for each patient and subjected to univariate and multivariate analysis.", 'With a median follow-up of 44 months, the actuarial local control rate at 4 years was 89% while the median overall survival was 22 months. The median age-adjusted CCI score was 5. The age-adjusted CCI was a significant predictor of overall survival on both univariate (p=0.002) and multivariate analysis (p=0.011). Patients with an age-adjusted CCI score of 3 or less had a median survival of 41 months versus only 11 months for those scoring 6 or more.

question:
Before clinical treatment and during transportation, the analgesic therapy offered to patients with painful knee trauma may be quite insufficient. We hypothesize that a femoral nerve blockade for analgesia can be administered in a preclinical setting at the injury site and provides better pain relief than intravenous metamizole, whose analgesic effect is comparable with that of opioids.', 'After an initial clinical investigation, 52 patients were randomized according to computer-generated codes; 26 patients received a femoral nerve blockade and 26 received metamizole. The treatment was started at the injury site and the level of pain on the 100-mm visual analog scale was assessed at the beginning and the end of treatment.', 'Pain and anxiety scores were significantly reduced by half in the femoral nerve blockade group; peripheral vasoconstriction was noted in 26 patients at the injury site and dropped to six at the time of arrival at the hospital. Two of 26 patients in the blockade group did not benefit from the treatment. In the metamizole group, pain and anxiety did not decrease significantly; vasoconstriction persisted in all patients.
