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.

Input: Consider Input: 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.

Input: Consider Input: We examined hypoxia-inducible protein 2, hypoxia-inducible factor-1alpha and nuclear factor-kappaB in acquired cystic disease of the kidney associated with renal cell carcinoma to elucidate the roles of these factors in cyst formation and subsequent tumor transformation.', 'Immunohistochemical expression of hypoxia-inducible protein 2, hypoxia-inducible factor-1alpha and phosphorylated nuclear factor-kappaB (active form) were examined in 20 normal kidney samples obtained from nephrectomy for localized renal cell carcinoma and 25 kidneys with acquired cystic disease associated renal cell carcinoma from 23 patients on dialysis.', 'Only faint or weak immunostaining for hypoxia-inducible protein 2, hypoxia-inducible factor-1alpha and phosphorylated nuclear factor-kappaB was observed in normal kidney tissues. In nontumor areas of the kidneys with acquired cystic disease expressions of these 3 proteins was up-regulated in tubular and cyst epithelial cells. Acquired cysts were classified into 3 types according to cyst epithelium morphology, namely flat, cuboidal and hyperplastic. Hyperplastic cysts were the predominant cysts expressing hypoxia-inducible protein 2 and hypoxia-inducible factor-1alpha. Although up-regulation of hypoxia-inducible protein 2, hypoxia-inducible factor-1alpha and phosphorylated nuclear factor-kappaB was observed in renal cell carcinoma, positive hypoxia-inducible protein 2 immunostaining was detected predominantly in papillary renal cell carcinoma, while positive hypoxia-inducible factor-1alpha and phosphorylated nuclear factor-kappaB immunostaining was prominent in clear cell renal cell carcinoma.

Input: Consider Input: Displacement Encoding with Stimulated Echoes (DENSE) encodes displacement into the phase of the magnetic resonance signal. The encoding frequency (ke) maps the measured phase to tissue displacement while the strength of the encoding gradients affects image quality. 2D cine DENSE studies have used a ke of 0.10\xa0cycles/mm, which is high enough to remove an artifact-generating echo from k-space, provide high sensitivity to tissue displacements, and dephase the blood pool. However, through-plane dephasing can remove the unwanted echo and dephase the blood pool without relying on high ke. Additionally, the high sensitivity comes with the costs of increased phase wrapping and intra-voxel dephasing. We hypothesized that ke below 0.10\xa0cycles/mm can be used to improve image characteristics and provide accurate measures of cardiac mechanics.', 'Spiral cine DENSE images were obtained for 10 healthy subjects and 10 patients with a history of heart disease on a 3\xa0T Siemens Trio. A mid-ventricular short-axis image was acquired with different ke: 0.02, 0.04, 0.06, 0.08, and 0.10\xa0cycles/mm. Peak twist, circumferential strain, and radial strain were compared between acquisitions employing different ke using Bland-Altman analyses and coefficients of variation. The percentage of wrapped pixels in the phase images at end-systole was calculated for each ke. The dephasing of the blood signal and signal to noise ratio (SNR) were also calculated and compared.', 'Negligible differences were seen in strains and twist for all ke between 0.04 and 0.10\xa0cycles/mm. These differences were of the same magnitude as inter-test differences. Specifically, the acquisitions with 0.04\xa0cycles/mm accurately quantified cardiac mechanics and had zero phase wrapping. Compared to 0.10\xa0cycles/mm, the acquisitions with 0.04\xa0cycles/mm had 9\xa0% greater SNR and negligible differences in blood pool dephasing.
