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.

To investigate the relationship between tissue elasticity before and after antiviral therapy and shear wave as well as strain elastography.', 'FibroScan and real-time tissue elastography were performed before and after antiviral therapy for chronic hepatitis C, and treatment efficacy and elastographic findings were comparatively analyzed. Elasticity was evaluated by measuring liver stiffness (LS) in kilopascals using FibroScan, and the liver fibrosis index (LFI) was assessed by real-time tissue elastography.', 'LS and LFI correlated well before and after therapy (r = 0.567, p = 0.003 and r = 0.576, p = 0.002, respectively). In the group without a sustained virological response (SVR), LS increased in 4 of 5 patients. Patients with an increase in both LS and LFI were all in the non-SVR group (3/3, 100%). In addition, LS increased in all patients except 1 in the non-SVR group (4/5, 80%). In the SVR group, both LS and LFI decreased in all patients except 1 (18/19, 94.7%). In the patient with an increase in LS despite achieving SVR, LS decreased quickly after alcohol cessation.

Secreted phospholipases A(2) (sPLA(2)s) are released in plasma and other biologic fluids of patients with inflammatory, autoimmune, and allergic diseases.', 'We sought to evaluate sPLA(2) activity in the bronchoalveolar lavage fluid (BALF) of asthmatic patients and to examine the expression and release of sPLA(2)s from primary human lung mast cells (HLMCs).', 'sPLA(2) activity was measured in BALF and supernatants of either unstimulated or anti-IgE-activated HLMCs as hydrolysis of oleic acid from radiolabeled Escherichia coli membranes. Expression of sPLA(2)s was examined by using RT-PCR. The release of cysteinyl leukotriene (LT) C(4) was measured by means of enzyme immunoassay.', 'Phospholipase A(2) (PLA(2)) activity was higher in the BALF of asthmatic patients than in the control group. BALF PLA(2) activity was blocked by the sPLA(2) inhibitors dithiothreitol and Me-Indoxam but not by the cytosolic PLA(2) inhibitor AZ-1. HLMCs spontaneously released a PLA(2) activity that was increased on stimulation with anti-IgE. This PLA(2) activity was blocked by dithiothreitol and Me-Indoxam but not by AZ-1. HLMCs constitutively express mRNA for group IB, IIA, IID, IIE, IIF, III, V, X, XIIA, and XIIB sPLA(2)s. Anti-IgE did not modify the expression of sPLA(2)s. The cell-impermeable inhibitor Me-Indoxam significantly reduced (up to 40%) the production of LTC(4) from anti-IgE-stimulated HLMCs.

Translationally controlled tumor protein (TCTP), alternatively called fortilin, is believed to be involved in the development of the chemoresistance of tumor cells against anticancer drugs such as etoposide, taxol, and oxaliplatin, the underlying mechanisms of which still remain elusive.', 'Cell death analysis of TCTP-overexpressing HeLa cells was performed following etoposide treatment to assess the mitochondria-dependent apoptosis. Apoptotic pathway was analyzed through measuring the cleavage of epidermal growth factor receptor (EGFR) and phospholipase C-γ (PLC-γ), caspase activation, mitochondrial membrane perturbation, and cytochrome c release by flow cytometry and western blotting. To clarify the role of TCTP in the inhibition of apoptosome, in vitro apoptosome reconstitution and immunoprecipitation was used. Pull-down assay and silver staining using the variants of Apaf-1 protein was applied to identify the domain that is responsible for its interaction with TCTP.', 'In the present study, we confirmed that adenoviral overexpression of TCTP protects HeLa cells from cell death induced by cytotoxic drugs such as taxol and etoposide. TCTP antagonized the mitochondria-dependent apoptotic pathway following etoposide treatment, including mitochondrial membrane damage and resultant cytochrome c release, activation of caspase-9, and -3, and eventually, the cleavage of EGFR and PLC-γ. More importantly, TCTP interacts with the caspase recruitment domain (CARD) of Apaf-1 and is incorporated into the heptameric Apaf-1 complex, and that C-terminal cleaved TCTP specifically associates with Apaf-1 of apoptosome in apoptosome-forming condition thereby inhibiting the amplification of caspase cascade.
