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.
question:
Fracture and low bone mineral density both have strong predictive value for future fractures. The risk of future fractures can be reduced by medi-cal treatment if patients with osteoporosis are identified, for example by screening fracture patients for low bone mineral density. We suggest that these screening routines be organized at orthopedics departments and we report our experience with such a screening system.', 'We screened all patients between 50-75 years of age with a wrist, vertebral, proximal humerus, or hip fracture visiting our orthopedics department by measuring bone mineral density (BMD) using DEXA scans. After diagnosis, the patients were referred to their primary care physician for treatment.', 'Between November 1, 2002, and October 31, 2003, 239 patients were investigated and only 13% had normal BMD values. 45% of the patients were diagnosed with osteopenia and 42% with osteoporosis.

question:
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.

question:
To investigate the specific role of Frizzled-related protein (FRZB) and Secreted frizzled-related protein 1 (SFRP1) in the onset and progression of Osteoarthritis (OA) using Frzb(-/-) and Sfrp1(-/-) mice in the destabilization of medial meniscus model (DMM), a slowly progressing model of OA. Secreted frizzled-related proteins (SFRPs) were identified as secreted Wingless-type (Wnt) antagonists. The Wnt signaling cascade is a major regulator in cartilage development, homeostasis and degeneration.', 'The DMM model was surgically induced in eight-week-old male C57/Bl6 Frzb(-/-), Sfrp1(-/-) or wild-type mice by transection of the medial meniscotibial ligament. Cartilage damage in the femoral and tibial articular surfaces was calculated following the Osteoarthritis Research Society International (OARSI) histopathology initiative guidelines. Histomorphometry was used to evaluate the subchondral bone plate thickness.', 'OA severity scores were significantly higher in the tibia of Frzb(-/-) mice as compared to littermates, whereas no interaction was seen between genotype and intervention in Sfrp1(-/-) mice. Moreover, the DMM model resulted in significantly greater subchondral bone changes compared to sham but was not different between Frzb(-/-) mice and littermates. In contrast, the subchondral bone properties in Sfrp1(-/-) mice were significantly different from littermates.
