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]: The IL-1 family of cytokines is known to play an important role in inflammation therefore understanding the mechanism by which they are produced is paramount. Despite the recent plethora of publications dedicated to the study of these cytokines, the mechanism by which they are produced in the airway following endotoxin, Lipopolysaccharide (LPS), exposure is currently unclear. The aim was to determine the mechanism by which the IL-1 cytokines are produced after LPS inhaled challenge.', 'Mice were challenged with aerosolised LPS, and lung tissue and bronchiolar lavage fluid (BALF) collected. Targets were measured at the mRNA and protein level; caspase activity was determined using specific assays.', 'BALF IL-1b/IL-18, but not IL-1a, was dependent on Ice Protease-Activating Factor (IPAF), and to a lesser extent Apoptosis-associated Speck-like protein containing a CARD (ASC). Interestingly, although we measured an increase in mRNA expression for caspase 1 and 11, we could not detect an increase in lung enzyme activity or a role for them in IL-1a/b production. Further investigations showed that whilst we could detect an increase in caspase 8 activity at later points in the time course (during resolution of inflammation), it appeared to play no role in the production of IL-1 cytokines in this model system.

[EX Q]: Recent research suggests that preintervention functional magnetic resonance imaging (fMRI) data may predict weight loss outcomes among patients who participate in a behavioral weight loss plan. No study has examined whether presurgical brain activation can predict outcomes following bariatric surgery.', 'The aim of the present study was to determine if brain activations during a presurgical fMRI food-motivation paradigm are associated with weight loss 3 and 6 months following laparoscopic adjustable gastric banding (LAGB). Nineteen participants viewed food and nonfood pictures from a well-established food motivation paradigm during an fMRI scanning session before LAGB surgery. Weight was assessed presurgery and 3 and 6 months postsurgery; data for all participants was available at each time point. fMRI data were analyzed using the BrainVoyager QX statistical package. Whole brain voxelwise correlations of presurgery (food-nonfood) brain activation and weight, corrected for multiple comparisons, were performed to analyze the relationship between presurgical brain activation and subsequent weight loss. The settings were a medical university brain imaging center and 2 surgical weight loss centers in a major metropolitan area.', 'Increased activity in frontal regions associated with cognitive control (medial, middle, superior frontal gyrus) and posterior cingulate cortex was associated with weight loss following LAGB.

[EX Q]: Systemic lupus erythematosus (SLE) is characterised by the presence of antibodies to double stranded DNA (dsDNA), which are involved in the pathogenesis of SLE. Previous studies showed that at least two thirds of patients develop a clinical relapse within six months after a significant rise in the anti-dsDNA level, and most relapses were prevented by the administration of corticosteroids at the time of the rise.', 'To determine whether mofetil mycophenolate (MMF) can prevent a clinical relapse without the side effects associated with corticosteroids.', '36 patients with SLE were examined monthly to determine whether a rise in anti-dsDNA level had occurred. A rise was defined as an increase of 25% of the level of the previous sample of at least 15 IU/ml within a four month period. After a rise patients were treated with MMF 2000 mg daily for six months. Patients were monitored monthly for the occurrence of a clinical relapse and to assess the serological activity and state of activation of CD4+, CD8+, and CD19+ lymphocyte subsets.', 'Anti-dsDNA rose in 10 patients. Treatment with MMF was started in all these patients, and after six months no clinical relapse had occurred. Side effects were minimal. Antibodies to dsDNA decreased during the treatment (p<0.001), associated with a decrease in the state of activation of CD19+ lymphocytes. No changes were found in the state of activation of CD4+ or CD8+ lymphocyte subsets.
