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.

Example Input: Dehydroepiandrosterone (DHEA) was shown to improve the immune function and survival in experimental sepsis. This study examined the effect of DHEA on intestinal leukocyte recruitment during experimental sepsis, considering factors of gender (male, female and ovariectomized female animals) and combined treatment using orthovanadate (OV) in two models of sepsis.', 'Male rats underwent colon ascendens stent peritonitis (CASP) or endotoxemia. DHEA was administered after induction of experimental sepsis. Changes in leukocyte adherence and capillary perfusion (measured as intestinal functional capillary density - FCD) were assessed using intravital microscopy. While DHEA increased baseline leukocyte adherence in control animals, DHEA reduced leukocyte adherence and increased FCD in male animals with CASP. These effects were also observed in DHEA-treated ovariectomized female rats with CASP. Similarly, the administration of DHEA reduced the number of adherent leukocytes to intestinal venules by 30% in the endotoxemia model. The combined treatment of DHEA and OV significantly reduced adherence of leukocytes to intestinal venules and improved FCD.

Example Input: The aim of this study was to describe the revascularization process of autogenous bone block grafts placed with or without an expanded polytetrafluoroethylene (e-PTFE) membrane.', 'Thirty Wistar male rats had their mandibles augmented by either an autogenous bone block graft (group A) or an autogenous bone block graft covered with an e-PTFE membrane (group B). The animals were sacrificed by perfusion at baseline, 3, 7, 14, and 21 days after surgery.', 'After 3 days, the presence of vascular sprouts derived from the recipient bed was observed in group A; more discrete sprouts were also observed in group B. After 7 days, revascularization continued, with vessels derived from both the recipient bed and the surrounding connective tissue in group A but only from the recipient bed in group B. At 14 days, group A showed penetration of vessels at the periphery of the graft; the vessels reached varying distances inside it. In group B, revascularization of the graft occurred mainly near its perforation, its borders, and at the recipient bed-graft interface. After 21 days, graft vascular penetration could be observed throughout the extent of the graft in group A but only approximately halfway through the graft in group B.

Example Input: To identify differences in perspectives that may complicate the process of joint decision making at the end of life, this study determined the agreement of family and staff perspectives about end-of-life experiences in nursing homes and residential care/assisted living communities and whether family and staff roles, involvement in care, and interaction are associated with such agreement.', 'This cross-sectional study examined agreement in 336 family-staff pairs of postdeath telephone interviews conducted as part of the Collaborative Studies of Long-Term Care. Eligible deaths occurred in or within 3 days of leaving one of a stratified random sample of 113 long-term care facilities in four states and after the resident had lived in the facility (3)15 days of the last month of life. McNemar p values and kappas were determined for each concordance variable, and mixed logistic models were run.', "Chance-adjusted family-staff agreement was poor for expectation of death within weeks (66.9% agreement, kappa = .33), course of illness (62.9%, 0.18), symptom burden (59.6%, 0.18), and familiarity with resident's physician (59.2%, 0.05). Staff were more likely than family to expect death (70.2% vs 51.5%, p < .001) and less likely to report low symptom burden (39.6% vs 46.6%, p = .07). Staff involvement in care related to concordance and perspectives of adult children were more similar to those of staff than were other types of family members.
