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:
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.

question:
The aim of this study was to investigate the effect of season of diagnosis on the outcome of patients with diffuse large B-cell lymphoma (DLBCL) and Hodgkin lymphoma (HL). In this study, we included curatively treated DLBCL (n = 5875) and HL (n = 1693) patients, diagnosed between 2000 and 2011, based on data from the Swedish Lymphoma Register.', 'Overall survival was significantly better for patients diagnosed with DLBCL during the summer months, but not for patients diagnosed with HL. The difference remained in a multivariable analysis adjusted for age, stage, performance status, number of extra nodal sites and year of diagnosis (HR 1.08; 95% CI 1.02-1.14, P = 0.0069). When analyzing the DLBCL patients according to gender in the multivariable model, the effect of season was shown to be restricted to male patients (HR = 1.09, 95% CI 1.01-1.17, P = 0.0269.

question:
Heparin is used in the treatment of venous and arterial thromboembolic events, including unstable angina. Once unfractionated heparin is discontinued during the acute phase of unstable angina, it has been demonstrated that the disease process may be reactivated within hours. It is hypothesized that this reactivation may be a result of direct platelet activation by heparin that can linger even after the drug itself has been stopped. Prior studies have shown that heparin can either increase or decrease platelet activation. More recent studies have also shown conflicting effects of unfractionated heparin on PFA-100 testing.', 'We studied the in-vitro effects of unfractionated heparin on platelet function and PFA-100 testing. Unfractionated heparin was incubated with whole blood taken from 18 healthy volunteers. Platelet activation and aggregation was assessed with and without the presence of heparin.', 'Platelet aggregation and activation were increased in the presence of heparin. Unfractionated heparin also significantly prolonged collagen/adenosine diphosphate closure time but did not affect collagen/epinephrine closure time.
