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.

Epinephrine is a component of all resuscitation algorithms. Vasopressin is a pulmonary vasodilator and systemic vasopressor. We investigated the effect of epinephrine vs. vasopressin on survival and hemodynamics after neonatal porcine cardiac arrest (CA).', 'A 4-min asphyxial CA was induced, after which cardiopulmonary resuscitation (CPR) was commenced. Animals were randomized to low- (LDE: 0.01 mg/kg) or high-dose epinephrine (HDE: 0.03 mg/kg), low- (LDV: 0.2 U/kg) or high-dose vasopressin (HDV: 0.4 U/kg), or control (saline). Clinical and echocardiography indexes were monitored.', 'Sixty-nine animals were randomized. Survival was greater in HDV (n = 8 (89%); P < 0.05 ANOVA) vs. control (n = 7 (43%)) and LDE (n = 5 (36%)) but not vs. HDE (n = 7 (64%)) or LDV (n = 6 (75%)). Animals resuscitated with LDE required more shocks (2.5 (interquartile range: 2-6); P < 0.05) and higher doses of energy (15 J (interquartile range: 10-20); P < 0.05). Left ventricular output was comparable between groups, but a greater increase in superior vena caval flow was seen after HDV (P < 0.001 vs. control, LDE, and HDE). Plasma troponin was greatest in the HDE group (P < 0.05 vs. control and HDV).

Ex Input:
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.

The purpose of this study was to assess liver-type fatty acid-binding protein (L-FABP) expression and its association with clinicopathological features in hepatocellular carcinoma (HCC).', 'L-FABP mRNA expression in 57 samples of HCC and corresponding adjacent liver tissue and 8 normal liver tissue samples were examined by real-time reverse transcriptase (RT)–PCR analyses. Tissue microarray technique and immunohistochemistry (IHC) were used to detect the expression of L-FABP in 163 HCCs. The association between L-FABP expression and the clinicopathological factors and prognosis was analyzed.', 'The average expression of L-FABP mRNA was 0.233 in the HCC tissues, 1.407 in the peri-carcinoma tissues, and 1.0 in the normal liver tissues. IHC analysis showed that there were 47% (76/163) HCCs exhibited weak or even no immunoreactivity of L-FABP. The L-FABP expression in HCC showed significant associations with preoperative levels of AFP (p=0.039), tumor size (p=0.026), histological grade (p=0.000), differential degree (p=0.000), vascular invasion (p=0.016), capsular invasion (p=0.029) and recurrence (p=0.004). Patients with L-FABP high-expression showed better prognosis than patients with L-FABP low-expression (p=0.008).
