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]: Neonatal therapy-resistant septic shock is a common problem in middle and low-income countries. We investigated whether newborn infants with infection and therapy-resistant hypotension showed evidence of abnormal levels of cortisol or cortisol precursors.', 'A total of 60 term or near term neonates with evidence of infection were enrolled after informed consent. Of these, 30 had an infection and refractory shock and 30 had an infection without shock. There were no detectable differences between the groups in the length of gestation, birth weight or gender distribution. Serum was obtained during days four and 14 after birth. Cortisol and cortisol precursor concentrations were analysed using liquid chromatography-tandem mass spectrometry.', 'The cortisol concentrations were low considering the expected responses to stress and they did not differ between the groups. The infants with infection and shock had higher serum dehydroepiandrosterone (DHEA) levels than those without shock (319.0 ± 110.3 μg/dL, versus 22.3 ± 18.3 μg/dL; p < 0.0001) and they also had higher 17-hydroxy-pregnenolone, pregnenolone and progesterone concentrations. There were no detectable differences in the levels of 17-hydroxy-progesterone, 11-deoxy-cortisol, cortisol or cortisone.

[EX Q]: Histone deacetylase (HDAC) inhibitors have been reported to improve essential and secondary hypertension. However, the specific HDAC that might serve as a therapeutic target and the associated upstream and downstream molecules involved in regulating hypertension remain unknown. Our study was aimed at investigating whether a selective inhibitor of class II HDAC (MC1568) modulates hypertension, elucidating the underlying mechanism.', 'Hypertension was established by administering angiotensin II (Ang II) to mice before treatment with MC1568. SBP was measured.', "Treatment with MC1568 reduced elevated SBP; attenuated arterial remodeling in the kidney's small arteries and thoracic aorta; and inhibited cell cycle regulatory gene expression, vascular smooth muscle cell (VSMC) proliferation, DNA synthesis, and VSMC hypertrophy in vivo and in vitro. Ang II enhanced the expression of phosphorylated HDAC4 and GATA-binding factor 6 (GATA6) proteins, which were specifically localized in the cytoplasm of cells in the arteries of kidneys and in aortas. Forced expression and knockdown of HDAC4 increased and decreased, respectively, the proliferation and expression of cell cycle genes in VSMCs. GATA6, a newly described binding partner of HDAC4, markedly enhanced the size and number of VSMCs. Calcium/calmodulin-dependent kinase IIα (CaMKIIα), but not HDAC4, translocated from the nucleus to the cytoplasm in response to Ang II. CaMKIIα and protein kinase D1 were associated with VSMC hypertrophy and hyperplasia via direct interaction with HDAC4. MC1568 treatment weakened the association between HDAC4 and CaMKIIα.

[EX Q]: To assess the safety and efficacy of vinorelbine in patients with AIDS-related Kaposi's sarcoma (KS).", 'From December 1994 to May 1997, within the Italian Cooperative Group on AIDS and Tumors, we enrolled 36 patients with AIDS-related KS who experienced disease progression after one or more regimens of systemic chemotherapy. Patients were treated with vinorelbine 30 mg/m(2) every 2 weeks by intravenous bolus.', 'Of 35 assessable patients, three (9%) had a clinical complete response and 12 (34%) had a partial remission, for an overall objective response rate of 43% (95% confidence interval, 26% to 61%). For the 15 patients with objective responses, the median duration of response from the beginning of therapy until the development of progression was 176 days, whereas the median progression-free survival and the median survival durations for 35 assessable patients were 151 days and 216 days, respectively. Vinorelbine also induced responses in patients who had become resistant to regimens that included other vinca alkaloids. Overall, vinorelbine was well tolerated. Toxicity, including neurologic toxicity, was mild and reversible. Neutropenia was the most frequent dose-limiting toxicity.
