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.

Although the majority of evidence does not support association between Helicobacter pylori infection and ischaemic heart disease, the nature of this relationship may differ when virulence of the infecting strains are examined.', 'The prevalence of IgG antibody evidence of infection with CagA positive stains of H. pylori was investigated in stored plasma samples from 259 cases of myocardial infarction (aged 25-70 years, 74 males) and 259 population based controls from the same area in Northern Ireland. Two-hundred and seventy (52.1%) subjects were seropositive for anti-CagA IgG. CagA seropositivity was more common in cases than in controls: 56.4 vs 47.9%, odds ratio for seropositivity in cases (95% CI) 1.41 (1.00, 1.99). Substantial attenuation of this relationship occurred on adjustment for age, sex, number of siblings, smoking and measures of socio-economic status: odds ratio (95% CI) 1.16 (0.79, 1.70). A similar pattern was seen for seropositivity for all H. pylori strains.

To evaluate manual lymphatic drainage (MLD) and active exercise effects on lymphatic alterations of the upper limb (UL), range of motion (ROM) of shoulder, and scar complications after breast cancer surgery.', 'Clinical trial.', 'Health care center.', 'Women (N=105) undergoing radical breast cancer surgery who were matched for staging, age, and body mass index.', 'Women (n=52) were submitted to MLD and 53 to active exercises for UL for 1 month and followed up.', 'Shoulder ROM, surgical wound inspection and palpation, UL circumference measurements, and lymphoscintigraphy were performed in preoperative and postoperative periods.', 'There was no significant difference between groups with regard to wound healing complications, ROM, and UL circumferences. After surgery, 25 (48.1%) of the MLD group and 19 (35.8%) of the active exercise group showed worsening in radiopharmaceutical uptake velocity, whereas 9 (17.3%) of the MLD group and 11 (20.8%) of the active exercise group showed improved velocity (P=.445). With regard to uptake intensity, 27 (51.9%) of the MLD group and 21 (39.6%) of the active exercise group showed worsening whereas 7 (13.5%) of the MLD group and 7 (13.2%) of the active exercise group showed some improvement (P=.391). The presence of collateral circulation was similar in both groups at both time points evaluated. The active exercise group had a significant increase in postoperative liver absorption (P=.005), and the MLD group had a significant increase in postoperative dermal backflow (P=.024).

We investigated the effects of PARS inhibition on intestinal injury in a canine model of cardiopulmonary bypass (CPB).', 'Twelve dogs underwent 90 minutes of hypothermic CPB. 6 dogs received 5 mg/kg PJ34, a selective PARP inhibitor during CPB, 6 vehicle-treated animals served as controls. Mesenteric blood flow (MBF) and mesenteric vascular resistance (MVR) were measured before and 60 minutes after weaning from CPB. Endothelium-dependent vasorelaxation to acetylcholine (ACH) and endothelium-independent vasorelaxation to sodium-nitroprusside (SNP) were expressed as percent change of MVR. In addition, mesenteric creatine kinase (CK) and lactate release were determined.', 'Baseline hemodynamics, MBF, response to ACH (- 41 +/- 3 vs. - 55 +/- 6 %) and SNP (- 60 +/- 2 vs. - 56 +/- 4 %) did not differ significantly between the groups. The response to ACH decreased significantly in the control group while it remained unchanged in the PJ34 group (- 29 +/- 5 vs. - 46 +/- 9 %, p < 0.05). The response to SNP did not change. Mesenteric CK release (325 +/- 99 vs. 16 +/- 10 U/l, p < 0.05) and lactate production (0.96 +/- 0.17 vs. 0.4 +/- 0.2 mmol/l, p < 0.05) were significantly lower in the PJ34 group.
