Definition: 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: The prevention of graft rejection after liver transplant with cyclosporine A (CyA) and tacrolimus has been associated to decreased bone mineral density. The aim of this study was to investigate the in vitro effects of increasing concentrations of CyA and tacrolimus on human osteoblasts.', 'Human osteoblast-like cells obtained by the outgrowth of cells from bone chips were exposed to tacrolimus (10-1000 ng/mL) or CyA (1000-50,000 ng/mL). Alkaline phosphatase (ALP) activity was determined on days 2, 4, 6, and 8, and cell proliferation was assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and cell counting on days 2, 4, 6, and 8. Cell death was investigated by flow cytometry with propidium iodine, and apoptosis was assessed by flow cytometry with fluorescently conjugated annexin V.', 'No effects of tacrolimus were detected with respect to ALP activity or cell proliferation. In CyA-treated cultures, concentrations greater than 10 000 ng/mL were associated with decreased ALP activity after 8 days (P<0.05). In addition, a dose-dependent reduction in cell proliferation was detected after 6 days (P<0.05). This decreased cell proliferation was associated with increased apoptosis in response to 50 000 ng/mL CyA.
