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.

[EX Q]: 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.

[EX Q]: Pulmonary hypertension (PH) is prognosti- cally important in chronic obstructive pulmonary disease (COPD). Since PH only weakly correlates with hypoxemia, other factors must play a role.', 'To investigate whether polymorphisms of the serotonin transporter (5HTT), serotonin-2a receptor (5HTR2a) and endothelial nitric oxide synthetase (eNOS) are related to PH in COPD.', 'In 59 COPD patients who underwent right heart catheterization, 6-min walking distance, NYHA functional class, pulmonary function tests, blood gases and 5HTT, 5HTR2a and eNOS (4ab and T298C) polymorphisms were determined.', 'Forty-nine COPD patients in NYHA functional class III-IV were included. Ten were excluded due to comorbid causes of PH (mainly chronic thromboembolic). PH (mPAP > or =25 mm Hg) was present in 55% and usually mild, but out of proportion (mPAP > or =40 mm Hg) in 12%. Patients with PH had significantly higher frequencies of the 5HTT-L-allele (52%) compared to individuals without PH (36%), and LL homozygote patients had more severe PH. In patients with out-of-proportion PH, the L-allelic frequency was even 75%. We found no association of 5HTR2a and eNOS polymorphism with PH in COPD.

[EX Q]: Loss of PTEN expression is one of the most prevalent and earliest molecular abnormalities associated with endometrial carcinogenesis. Given that PTEN is often absent and telomerase is overexpressed by endometrial cancers, we hypothesize that PTEN signaling is important in telomerase regulation.', 'PTEN expression was reconstituted in the PTEN-null Ishikawa endometrial cancer cells by adenovirus-mediated gene transduction. Cell proliferation was evaluated 12-96 h after infection. Western blot analysis was performed to assess PTEN status and phosphorylated Akt expression. Telomerase activity was determined by the telomeric repeat amplification protocol (TRAP) assay. hTERT mRNA levels were assessed by real-time RT-PCR. Ishikawa cells were also treated with LY294002, a PI3-kinase inhibitor.', 'Infection of Ishikawa cells by replication-defective recombinant adenovirus expressing wild-type PTEN, but not control adenovirus or adenovirus expressing lipid phosphatase defective PTEN GE mutant, inhibited constitutive Akt activation and suppressed proliferation of Ishikawa cells. Infection by wild-type PTEN adenovirus, but not control adenovirus, inhibited telomerase activity 24 h after infection. This inhibition of telomerase activity was parallel to decreased hTERT mRNA levels. LY294002 treatment resulted in dose-dependent inhibition of Akt activation and cellular proliferation. LY294002 suppressed telomerase activity and decreased hTERT transcript levels in a dose-dependent manner.
