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: Whether moderate to severe obesity (body mass index (BMI)30 to <40kg/m(2)) contributes to breast cancer recurrence and mortality remains uncertain.', '1199 women, recruited within 12 months of their diagnosis of hormone receptor positive (HR+), human epidermal growth factor receptor 2 negative (HER2-) invasive breast cancer completed an enrolment questionnaire and an annual follow-up questionnaire every 12 months for another 5 years. The impact of obesity on time to either local or distant recurrence or new breast cancer, or death due to breast cancer was determined by Cox regression. Women in the most extreme categories of BMI (<18.5 and 40) were excluded from the analysis.', 'Of the 1155 included women, mean age, 58.411.6 years, 53.8% had Stage 1 disease and 88.9% received oral adjuvant endocrine therapy (OAET) within 2 years of diagnosis. The likelihood of an event was significantly associated with moderate to severe obesity (HR=1.71, 95%CI, 1.12-2.62, p=0.014), disease beyond Stage 1 (HR=2.87, 95% CI 1.73-4.75, p<0.001), OAET (HR=0.26, 95%CI 0.14-0.46, p<0.001), mastectomy (HR=3.28, 95%CI 1.98-5.44, p<0.001) and radiotherapy (HR=2.12, 95%CI 1.24-3.63, p=0.006). For Stage 1 disease, only moderate to severe obesity (HR 3.23, 95%CI 1.48-7.03, p=0.003) and OAET use (HR 0.41, 95%CI 0.17-0.98, p=0.046) were significantly associated with an event.

Input: Consider Input: To investigate the potential of specific angiotensin II subtype 1 (AT1) receptor blockade to modify the mesenteric hemodynamic response to acute hypovolemia and retransfusion.', 'Prospective, randomized, controlled experimental study.', 'University-affiliated animal research laboratory.', 'Fasted, anesthetized, ventilated, juvenile domestic pigs of both sexes.', 'Acute, graded hypovolemia by 20% and 40% of the total estimated blood volume followed by retransfusion in control animals (CTRL; n = 10) and animals pretreated with the AT1 receptor blocker candesartan (CAND; n = 10).', 'Invasive monitoring of arterial and central venous blood pressures, cardiac output, portal venous blood flow, and jejunal mucosal blood flow. Blood gases were repeatedly analyzed to calculate oxygen delivery and consumption. Thirty minutes after each level of hypovolemia at 20% and 40%, cardiac output was decreased in CTRL animals from a baseline of 2.9 +/- 0.1 to 1.8 +/- 0.2 and 1.1 +/- 0.2 L/min, with no differences compared with CAND animals. Cardiac output was restored to 3.0 +/- 0.3 L/min 30 mins after retransfusion in CTRL animals, with no significant intergroup differences. Baseline portal venous blood flow (Q(MES)) and jejunal mucosal perfusion (PU(JEJ)) were greater in CAND animals compared with CTRL animals. During graded hypovolemia, CAND animals maintained Q(MES) and PU(JEJ) at significantly higher levels compared with CTRL animals, particularly after 40% hemorrhage (+221% and + 244%, respectively, relative to the mean values in CTRL animals). The same pattern was observed after retransfusion. Moreover, the calculated mesenteric critical oxygen delivery was significantly greater in CTRL animals (74 mL/min) compared with CAND animals (34 mL/min). No animals died in the CAND group, whereas four animals died during 40% hypovolemia or retransfusion in the CTRL group.

Input: Consider Input: The anti-inflammatory effect of low-dose radiotherapy (LD-RT) still is not understood. The adhesion of leukocytes to endothelial cells (EC) of the vessel wall is the initial event of tissue invasion, and thus, crucially contributes to the regulation of inflammation. We investigated the influence of LD-RT on the adhesion process in vitro.', 'Isolated peripheral-blood-mononuclear-cells (PBMC) were incubated with an activated murine endothelioma cell-line under shear conditions at 4 degrees C after irradiation with single doses between 0.1 and 10.0 Gy. Adherent cells were counted microscopically and compared to a non-irradiated control. In parallel, viability and expression of adhesion molecules, especially of L-selectin, and lineage-specific markers on the cell surface were determined by dye exclusion and cytofluorometry, respectively. Modulation of adhesion by soluble L-selectin was tested in the adhesion assay.', 'Radiation doses of 0.1-0.5 Gy reduced the adhesion of viable PBMC to EC in vitro by 70% of the control level 4 h after irradiation. Leukocytes showed a marked reduction of L-selectin expression after LD-RT. Soluble L-selectin can inhibit the adhesion of PBMC to EC.
