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: To explore the role of SCF/c-Kit signaling in the invasion of bladder cancer T24 cells.', 'Western blotting was used to detect the expression of c-Kit and PI3K pathway activation stimulated by stem cell factor (SCF) in T24 cells. The invasiveness of T24 cells before and after SCF stimulation and Wortmannin (aspecific PI3K inhibitor) treatment was evaluated using Transwell invasion assay (direct and indirect counting methods).', 'T24 cells expressed c-Kit protein and showed obvious Akt phosphorylation after stimulation with SCF (1 ng/ml) for 24 h. Compared to the control group, SCF stimulation (1 ng/ml) caused a greater number of T24 cells to migrate through the polycarbonate film (P<0.01), and this effect was blocked by the application of Wortmannin before the stimulation.

Question: In France, when physicians in ambulances take care of patients, they report medical status to the dispatch centre. Then the dispatching physician search for the available and appropriate hospital service to agree in directly receiving the patient. We attempted to evaluate this direct admission dispatch, in a urban area, with many health care facilities.', 'Prospective evaluation.', 'All the files for out of hospital interventions with a dispatch process were included. Data collected and analysed were: main pathologies, started time and end time of direct admission dispatch process and number of services called before finding the right place.', '959 patients files were included, 849 could be analysed. The average duration of direct admission dispatch process is 10 (+/-13) minutes. Traumatology speciality shows a longer dispatch process than medicine disease (p < 0.001), and this time increased during summer (p < 0.05). The other parameters did not influence this duration.

Question: The circadian clocks are internal timing mechanisms that drive ∼24-hour rhythms in a tissue-specific manner. Many aspects of the physiology of the intervertebral disc (IVD) show clear diurnal rhythms. However, it is unknown whether IVD tissue contains functional circadian clocks and if so, how their dysregulation is implicated in IVD degeneration.', 'Clock gene dynamics in ex vivo IVD explants (from PER2:: luciferase (LUC) reporter mice) and human disc cells (transduced with lentivirus containing Per2::luc reporters) were monitored in real time by bioluminescence photon counting and imaging. Temporal gene expression changes were studied by RNAseq and quantitative reverse transcription (qRT)-PCR. IVD pathology was evaluated by histology in a mouse model with tissue-specific deletion of the core clock gene Bmal1.', 'Here we show the existence of the circadian rhythm in mouse IVD tissue and human disc cells. This rhythm is dampened with ageing in mice and can be abolished by treatment with interleukin-1β but not tumour necrosis factor α. Time-series RNAseq revealed 607 genes with 24-hour patterns of expression representing several essential pathways in IVD physiology. Mice with conditional knockout of Bmal1 in their disc cells demonstrated age-related degeneration of IVDs.
