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.

Example Input: Mannose-binding lectin (MBL) is a key component of innate immunity. The expression of cortical MBL is up-regulated after clinical and experimental head trauma. This study aimed to assess the association of serum MBL levels with injury severity and long-term clinical outcomes after severe traumatic brain injury (STBI).', 'Serum MBL levels were measured in 122 patients and 100 healthy controls. Multivariate analyses were used to analyze the relationship between serum MBL levels and trauma severity reflected by Glasgow Coma Scale scores as well as between serum MBL levels and 6-month mortality and unfavorable outcome (Glasgow Outcome Scale score: 1-3). A receiver operating characteristic (ROC) curve was structured to evaluate the prognostic predictive performance of serum MBL levels.', 'Compared with healthy controls, serum MBL levels of patients were markedly elevated. Using multivariate analyses, serum MBL levels were found to be associated closely with Glasgow Coma Scale (GCS) scores and MBL emerged as an independent predictor for 6-month mortality and unfavorable outcome. Under ROC curve, serum MBL levels and GCS scores possessed similar prognostic predictive values.

Example Input: Hydrocortisone therapy is based on a dosing regimen derived from estimates of cortisol secretion, but little is known of how the dose should be distributed throughout the 24 h. We have used deconvolution analysis of 24-h serum cortisol profiles to determine 24-h cortisol secretion and distribution to inform hydrocortisone dosing schedules in young children and older adults.', 'Twenty four hour serum cortisol profiles from 80 adults (41 men, aged 60-74 years) and 29 children (24 boys, aged 5-9 years) were subject to deconvolution analysis using an 80-min half-life to ascertain total cortisol secretion and distribution throughout the 24-h period.', 'Mean daily cortisol secretion was similar between adults (6.3 mg/m(2) body surface area/day, range 5.1-9.3) and children (8.0 mg/m(2) body surface area/day, range 5.3-12.0). Peak serum cortisol concentration was higher in children compared with adults, whereas nadir serum cortisol concentrations were similar. Timing of the peak serum cortisol concentration was similar (07.05-07.25), whereas that of the nadir concentration occurred later in adults (midnight) compared with children (22.48) (P = 0.003). Children had the highest percentage of cortisol secretion between 06.00 and 12.00 (38.4%), whereas in adults this took place between midnight and 06.00 (45.2%).

Example Input: Exposure to fine particulate air pollution is associated with increased cardiovascular morbidity and mortality. We previously demonstrated that exposure to dilute diesel exhaust causes vascular dysfunction in humans.', 'We conducted a study to determine whether exposure to ambient particulate matter causes vascular dysfunction.', 'Twelve male patients with stable coronary heart disease and 12 age-matched volunteers were exposed to concentrated ambient fine and ultrafine particles (CAPs) or filtered air for 2 hr using a randomized, double-blind cross-over study design. We measured peripheral vascular vasomotor and fibrinolytic function, and inflammatory variables-including circulating leukocytes, serum C-reactive protein, and exhaled breath 8-isoprostane and nitrotyrosine-6-8 hr after both exposures.', 'Particulate concentrations (mean +/- SE) in the exposure chamber (190+/-37 microg/m(3)) were higher than ambient levels (31+/-8 microg/m(3)) and levels in filtered air (0.5+/-0.4 microg/m(3); p<0.001). Chemical analysis of CAPs identified low levels of elemental carbon. Exhaled breath 8-isoprostane concentrations increased after exposure to CAPs (16.9+/-8.5 vs. 4.9+/-1.2 pg/mL, p<0.05), but markers of systemic inflammation were largely unchanged. Although there was a dose-dependent increase in blood flow and plasma tissue plasminogen activator release (p<0.001 for all), CAPs exposure had no effect on vascular function in either group.
