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: To provide optimal treatment of heterogeneous triple negative breast cancer (TNBC), we need biomarkers that can predict the chemotherapy response.', 'We retrospectively investigated BRCAness in 73 patients with breast cancer who had been treated with taxane- and/or anthracycline-based neoadjuvant chemotherapy (NAC). Using multiplex, ligation-dependent probe amplification on formalin-fixed core needle biopsy (CNB) specimens before NAC and surgical specimens after NAC. BRCAness status was assessed with the assessor unaware of the clinical information.', 'We obtained 45 CNB and 60 surgical specimens from the 73patients. Of the 45 CNB specimens, 17 had BRCAness (38.6% of all subtypes). Of the 23 TNBC CNB specimens, 14had BRCAness (61% of TNBC cases). The clinical response rates were significantly lower for BRCAness than for non-BRCAness tumors, both for all tumors (58.8% vs. 89.3%, P= .03) and for TNBC (50% vs. 100%, P= .02). All tumors that progressed with taxane therapy had BRCAness. Of the patients with TNBC, those with non-BRCAness cancer had pathologic complete responses significantly more often than did those with BRCAness tumors (77.8%vs. 14.3%, P= .007). After NAC, the clinical response rates were significant lower for BRCAness than for non-BRCAness tumors in all subtypes (P= .002) and in TNBC cases (P= .008). After a median follow-up of 26.4 months, 6 patients-all with BRCAness-had developed recurrence. Patients with BRCAness had shorter progression-free survival than did those with non- BRCAness (P=.049).

Example Input: Low back pain is common and originates in the sacroiliac (SI) joint in 15%-30% of cases. Traditional SI joint disruption/degenerative sacroiliitis treatments include nonoperative care or open SI joint fusion. To evaluate the usefulness of newly developed minimally-invasive technologies, the costs of traditional treatments must be better understood. We assessed the costs of nonoperative care for SI joint disruption to commercial payers in the United States (US).', 'A retrospective study of claim-level medical resource use and associated costs used the MarketScan®️ Commercial Claims and Encounters as well as Medicare Supplemental Databases of Truven Healthcare. Patients with a primary ICD-9-CM diagnosis code for SI joint disruption (720.2, 724.6, 739.4, 846.9, or 847.3), an initial date of diagnosis from January 1, 2005 to December 31, 2007 (index date), and continuous enrollment for 1 year before and 3 years after the index date were included. Claims attributable to SI joint disruption with a primary or secondary ICD-9-CM diagnosis code of 71x.xx, 72x.xx, 73x.xx, or 84x.xx were identified; the 3-year medical resource use-associated reimbursement and outpatient pain medication costs (measured in 2011 US dollars) were tabulated across practice settings. A subgroup analysis was performed among patients with lumbar spinal fusion.', 'The mean 3-year direct, attributable medical costs were $16,196 (standard deviation [SD] $28,592) per privately-insured patient (N=78,533). Among patients with lumbar spinal fusion (N=434), attributable 3-year mean costs were $91,720 (SD $75,502) per patient compared to $15,776 (SD $27,542) per patient among patients without lumbar spinal fusion (N=78,099). Overall, inpatient hospitalizations (19.4%), hospital outpatient visits and procedures (14.0%), and outpatient pain medications (9.6%) accounted for the largest proportion of costs. The estimated 3-year insurance payments attributable to SI joint disruption were $1.6 billion per 100,000 commercial payer beneficiaries.

Example Input: Expression of osteopontin correlates with tumor progression and metastasis. The mechanisms by which osteopontin promotes tumor cell survival remain unclear. Here we used short-hairpin RNA-mediated gene silencing to investigate the antitumor effects by osteopontin depletion in hepatocellular carcinoma (HCC).', 'We applied polyethylenimine nanoparticles to deliver a short-hairpin RNA for depletion of osteopontin expression in HCC cells. Tumorigenicity and metastatic potentials of HCC cells were studied in vitro and in nude mice. Nuclear factor-kappaB (NF-kappaB) activation was analyzed by gel shift assay and luciferase analysis. The expressions of integrins were examined by real-time reverse-transcription polymerase chain reaction. Apoptosis was examined by terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling assay and mitochondrial membrane potential analysis.', 'Down-regulation of osteopontin inhibited HCC cell growth, anchorage-independent growth, adhesion with fibronectin and invasion through extracellular matrix in vitro, and suppressed tumorigenicity and lung metastasis in nude mice. Osteopontin silencing resulted in suppression of alphav, beta1, and beta3 integrin expressions, blockade of NF-kappaB activation, inhibition of Bcl-2/Bcl-xL and XIAP expressions, increase of Bax expression, and induction of a mitochondria-mediated apoptosis. Furthermore, down-regulation of osteopontin inhibited drug-induced NF-kappaB activation and sensitized HCC cells to chemotherapeutic agents in vitro, which led to complete regression of HCC xenografts in nude mice.
