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: Dilated cardiomyopathy (DCM) is a major cause of heart failure that may require heart transplantation. Approximately one third of DCM cases are familial. Next-generation DNA sequencing of large panels of candidate genes (ie, targeted sequencing) or of the whole exome can rapidly and economically identify pathogenic mutations in familial DCM.', 'We recruited 64 individuals from 26 DCM families followed at the Montreal Heart Institute Cardiovascular Genetic Center and sequenced the whole exome of 44 patients and 2 controls. Both affected and unaffected family members underwent genotyping for segregation analysis.', 'We found 2 truncating mutations in BAG3 in 4 DCM families (15%) and confirmed segregation with disease status by linkage (log of the odds [LOD] score = 3.8). BAG3 nonsense mutations conferred a worse prognosis as evidenced by a younger age of clinical onset (37 vs 48 years for carriers and noncarriers respectively; P = 0.037). We also found truncating mutations in TTN in 5 families (19%). Finally, we identified potential pathogenic mutations for 9 DCM families in 6 candidate genes (DSP, LMNA, MYH7, MYPN, RBM20, and TNNT2). We still need to confirm several of these mutations by segregation analysis.

Example Input: Morbidly obese patients usually present vitamin D deficiency or secondary hyperparathyroidism. Low vitamin D levels have been recently related to non-alcoholic fatty liver disease (NAFLD). The aim of this study was to analyse the relationship between vitamin D, bone turnover markers and non-alcoholic fatty liver disease and metabolic syndrome in severely obese patients.', 'One hundred and ten patients who underwent bariatric surgery were included. Liver biopsy was taken during surgery. Two univariate analyses were carried out in order to i) analyse the relationship between liver histology and vitamin D-bone turnover markers (intact parathyroid hormone (PTH), osteocalcin and Carboxy-terminal collagen crosslinks) and ii) establish the association between metabolic syndrome components-insulin resistance (HOMA) and vitamin D-bone turnover markers.', '70% of the patients had lower levels of vitamin D or secondary hyperparathyroidism. None of the components of liver histology were associated with levels of vitamin D or with bone turnover parameters. Patients with metabolic syndrome showed lower levels of PTH and osteocalcin (72,42 (29,47) vs 61.25(19.59) p-Value: 0.022; 19.79 (10.43) vs 16.87(10.25) p-Value: 0,028, respectively). HOMA was not related to Vitamin D or bone turnover markers.

Example Input: On cross-linking of receptor-bound IgE antibodies by allergens, effector cells (basophils and mast cells) involved in type I allergic reactions degranulate and release the potent chemical mediators stored inside their granules. Total and allergen-specific IgE concentrations, IgE affinity for allergen, and IgE clonality are all distinct properties of allergic patients' IgE repertoires. However, the inability to isolate individual IgE antibodies from allergic patients' sera presents a major barrier to understanding the importance of patient-specific IgE repertoires for the manifestation and severity of allergic symptoms.", 'We sought to investigate how individual properties of an IgE repertoire affect effector cell degranulation.', 'A panel of recombinant IgE (rIgE) antibodies specific for the major house dust mite allergen Der p 2 was developed and characterized in regard to Der p 2 affinity, as well as Der p 2 epitope specificity, by using surface plasmon resonance technology. Human basophils were sensitized with different combinations of rIgEs, and degranulation responses were measured by means of flow cytometry after challenge with Der p 2.', 'A total of 31 Der p 2-specific rIgEs were produced. They bound a total of 9 different Der p 2 epitopes in the affinity range (K(D) value) of 0.0358 to 291 nM. Factors increasing human basophil degranulation were increased total IgE concentrations, increased concentrations of allergen-specific IgE relative to non-allergen-specific IgE, more even concentration of individual allergen-specific IgE clones, increased IgE affinity for allergen, and increased number of allergen epitopes recognized by the IgE repertoire (increased IgE clonality).
