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: To study the presence of citrullinated proteins in inflammatory conditions and in clinically non-affected tissues of controls.', 'Synovial biopsy specimens from 19 patients with rheumatoid arthritis and 10 healthy controls were investigated by immunohistochemistry. Additionally, muscle tissue from 5 patients with polymyositis and from 7 healthy controls, intestinal tissue from macroscopically affected and non-affected areas from 10 patients with inflammatory bowel disease (IBD) and tonsil tissues from 4 chronically inflamed tonsils were studied.', 'Citrullinated proteins were present in all synovial biopsy specimens from patients with rheumatoid arthritis, whereas only three of 10 healthy synovial biopsy specimens showed scarce amounts of citrullination. Citrullination was also present in all myositis-affected muscles, whereas it was absent in the muscle tissues of controls. All tonsil biopsy specimens studied were positive for citrulline. Even though more frequently detected in the macroscopically affected colonic areas, no marked difference was observed in the pattern or extent of citrullination between the macroscopically affected and non-affected intestinal IBD tissues.

Input: Consider Input: Role of mast cells in the development of allergen-induced airway remodelling has not been fully investigated in vivo.', 'To clarify the possible role of mast cells in the development of allergen-induced airway remodelling, we compared their responses of genetically mast cell-deficient mice, WBB6F1-W/Wv (c-kit mutant) and Sl/Sld (c-kit ligand mutant) mice with those of congenic normal mice in a murine model of allergic asthma.', 'Mice were sensitized to ovalbumin (OA) with alum, and exposed daily for 3 weeks to aerosolized OA. Twenty-four hours after the last inhalation, bronchial responsiveness to acetylcholine (Ach) was measured, and bronchoalveolar lavage (BAL), and biochemical and histological examinations were performed.', 'In both sensitized mast cell-deficient mice, the degree of bronchial hyper-responsiveness to Ach, the number of inflammatory cells and the level of transforming growth factor-beta1 in BAL fluid, IgE response and goblet cell hyperplasia in the epithelium after repeated allergen provocation were not significantly different from those of congenic mice. In contrast, subepithelial fibrosis, evaluated in the fibrotic area around the airways, observed in congenic mice after repeated allergen challenge was partially attenuated in both mast cell-deficient mice. In addition, the amount of hydroxyproline in the lung of mast cell-deficient mice was significantly lower than that of congenic mice. Furthermore, the decreased fibrotic area and amount of hydroxyproline in W/Wv mice was completely recovered by reconstitution of tissue mast cells with bone marrow-derived mast cells of congenic mice.

Input: Consider Input: Non-response to cardiac resynchronization therapy (CRT) might be due to insufficient resynchronization as a result of a sub-optimal left ventricular lead positon (LV-LP).', 'To evaluate the impact of different LV-LPs on mortality and symptomatic improvement in a large cohort of patients treated with CRT.', "We performed a nationwide cohort study on consecutive patients receiving a CRT device from 1997 to 2012 registered in the Danish pacemaker and ICD register. The LV-LP was defined clockwise in a left anterior oblique (LAO) view and categorized as anterior (2 o'clock), lateral (2 to 4 o'clock) or posterior (>4 o'clock), and as basal, mid-ventricular, or apical in a right anterior oblique (RAO) view. Outcomes were all cause mortality and clinical response (improvement in NYHA class). Adjusted hazard ratio (aHR) and odds ratio (aOR) with 95% confidence intervals (CI) were calculated using Cox and logistic regression analysis.", 'A total of 2594 patients were included. A lateral LV-LP, (aHR 0.77, 95% CI 0.64-0.92, p=0.004), and a posterior LV-LP, (aHR 0.71 95% CI 0.53-0.97, p=0.029) were associated with lower mortality as compared to an anterior LV-LP. A lateral LV-PV was associated with higher clinical response rate as compared to an anterior LV-LP (aOR 1.37, 1.03-1.83, p=0.032). No statistically significant associations were observed between LV-LP in the RAO view and mortality or clinical response.
