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.

Flow-mediated dilation (FMD) is a complex mechanism involving several mediators, and different hemodynamic forces. Temporally distinct FMD patterns can be elicited by ischemic stimulus. Some subjects dilate early after cuff release, while others dilate later or do not dilate at all. Aim of the present research was to verify if hemorheological and hemodynamic factors might influence different FMD pattern.', '148 free-living subjects were studied. FMD was measured at 50 s, 2 min and 3 min. Blood viscosity was measured and shear stress calculated. Shear stress stimulus was quantified as the area under the curve after ischemia (SSAUC) over the first 40-s post-occlusion.', 'Based on the timing or absence of arterial dilation, 82 subjects were classified as Early dilators, 37 as Late dilators and 29 as No dilators. Peak FMD was 7.9 ± 4.3 % in Early dilators, and 9.1 ± 5.7 in Late dilators (p = NS). SSAUC was not significantly different among three groups, while blood viscosity was significantly higher in Late FMD subjects. Regression analyses showed the independent predictive role of age and blood viscosity on FMD patterns, and the lack of any association between FMD pattern and the magnitude of SS.

Non-shockable rhythms represent an increasing proportion of reported cases of out-of-hospital cardiac arrest but with an associated poor prognosis. In the present study, we investigated the effects of hydrogen inhalation on cardiac and neurological function after cardiopulmonary resuscitation and compared the therapeutic benefit with hypothermia in an asphyxial rat model of cardiac arrest.', 'Cardiopulmonary resuscitation was initiated after 5 min of untreated asphyxial cardiac arrest. Animals were randomly assigned to three experimental groups immediately after successful resuscitation: ventilation with 2% hydrogen/98% oxygen under normothermia (H2 inhalation), ventilation with 2% nitrogen/98% oxygen under normothermia (Control), and ventilation with 2% nitrogen/98% oxygen under hypothermia (TH). Mixed gas inhalation continued for 1 h while hypothermia continued for 2\u200ah. Animals were observed up to 96\u200ah for assessment of survival and neurologic recovery.', 'No statistical differences in baseline measurements were observed among groups and all the animals were successfully resuscitated. Serum cardiac troponin T and S100B measured during earlier post-resuscitation period were markedly reduced in both H2 inhalation and hypothermic groups. However, significantly better left ventricular ejection fraction, cardiac work, and neurological deficit score were observed in the H2 inhalation group. Ninety-six hours survival rate was significantly higher in the H2 inhalation group (75.0%), either compared with TH (45.8%) or compared with Control (33.3%). But there was no statistical difference between TH and Control.

To compare the rate of parastomal hernia in patients undergoing anterior fascial fixation of the ileal conduit with that in patients without fascial fixation. Limited data exist on whether anterior fascial fixation of the ileal conduit impacts the rate of parastomal hernia.', 'A total of 496 consecutive patients undergoing radical cystectomy and ileal conduit reconstruction from 1995 to 2012 were retrospectively evaluated for parastomal hernia. All patients had a 2-fingerbreadth aperture and the ileal conduit brought through the rectus muscle and sheath. Patients were divided into 1 of 3 groups based on stoma fixation and/or reinforcement: anterior fascial fixation, posterior reinforcement, or no fascial fixation. A parastomal hernia was defined as a palpable bulge at the stoma site. Multivariate logistic regression was conducted for the primary end point of parastomal hernia, controlling for other patient- and treatment-related factors that might affect the rate of parastomal hernia.', 'Median follow-up was 16 months (range, 1-189 months). The parastomal hernia rate was significantly greater in the anterior fascial suture group (43 of 281; 15.3%) than the no fascial suture group (12 of 164; 7.3%; P=.02). Multivariate logistic regression analysis modeled for the occurrence of a parastomal hernia demonstrated that anterior fascial fixation was an independent predictor of the development of parastomal hernia (odds ratio, 2.3; 95% confidence interval, 1.03-5.14; P=.04).
