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.

[EX Q]: Transfusion of packed erythrocytes stored for a long duration is associated with increased pulmonary arterial pressure and vascular resistance. Prolonged storage decreases erythrocyte deformability, and older erythrocytes are rapidly removed from the circulation after transfusion. The authors studied whether treating stored packed ovine erythrocytes with NO before transfusion could prevent pulmonary vasoconstriction, enhance erythrocyte deformability, and prolong erythrocyte survival after transfusion.', 'Ovine leukoreduced packed erythrocytes were treated before transfusion with either NO gas or a short-lived NO donor. Sheep were transfused with autologous packed erythrocytes, which were stored at 4°C for either 2 ("fresh blood") or 40 days ("stored blood"). Pulmonary and systemic hemodynamic parameters were monitored before, during, and after transfusion. Transfused erythrocytes were labeled with biotin to measure their circulating lifespan. Erythrocyte deformability was assessed before and after NO treatment using a microfluidic device.', 'NO treatment improved the deformability of stored erythrocytes and increased the number of stored erythrocytes circulating at 1 and 24\u2009h after transfusion. NO treatment prevented transfusion-associated pulmonary hypertension (mean pulmonary arterial pressure at 30\u2009min of 21\u2009±\u20091 vs. 15\u2009±\u20091 mmHg in control and NO-treated packed erythrocytes, P < 0.0001). Washing stored packed erythrocytes before transfusion did not prevent pulmonary hypertension.

[EX Q]: To determine whether anxiety and depression are associated with greater respiratory discomfort in asthma.', 'Adults with asthma (n = 230) underwent methacholine (Mch) challenge. Anxiety and depression, asthma control, and quality of life were evaluated at study entry by using the Hospital Anxiety and Depression Scale, Asthma Control Test, and Asthma Quality of Life Questionnaire, respectively. Qualitative descriptors of breathlessness, dyspnea intensity (modified Borg scale and visual analog scale [VAS]), and other respiratory symptoms were evaluated before and after Mch challenge.', 'Patients were classified as neither anxiety nor depression (NAD), anxiety only, depression only (D), or both anxiety and depression (AD) according to the Hospital Anxiety and Depression Scale score. Asthma Control Test and Asthma Control Test, and Asthma Quality of Life Questionnaire scores were lowest in the AD group (both p < 0.001). VAS scores for dyspnea and wheezing before Mch challenge were highest in the AD group (both p < 0.05). The increase in the modified Borg scale score after Mch challenge was higher in the AD group (mean [standard deviation] 2.5 ± 2.0) than in the NAD (1.5 ± 1.5) and D (0.8 ± 0.9) groups (p = 0.006 and p = 0.003, respectively). Most descriptors of breathlessness were more prevalent in the anxiety only, D, and AD groups than in the NAD group. Multivariable logistic regression models indicated that anxiety increased the risk of dyspnea (odds ratio 1.10, p < 0.001 for the Borg score; odds ratio 3.84, p = 0.032 for the VAS score) but not for other respiratory symptoms.

[EX Q]: Thus far, live attenuated SIV has been the most successful method for vaccinating macaques against pathogenic SIV challenge; however, it is not clear what mechanisms are responsible for this protection. Adoptive transfer studies in mice have been integral to understanding live attenuated vaccine protection in models like Friend virus. Previous adoptive transfers in primates have failed as transferred cells are typically cleared within hours after transfer.', 'Here we describe adoptive transfer studies in Mauritian origin cynomolgus macaques (MCM), a non-human primate model with limited MHC diversity. Cells transferred between unrelated MHC-matched macaques persist for at least fourteen days but are rejected within 36 hours in MHC-mismatched macaques. Cells trafficked from the blood to peripheral lymphoid tissues within 12 hours of transfer.
