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: Renal dysfunction is common after liver transplantation (LT). The aim of our study was to assess the prevalence of renal dysfunction 5 yr after LT and to identify risk factors for the development of this complication.', 'A total of 134 adult patients underwent LT from 1987 to 1998 and 74.6% of them were alive 5 yr after. Pre-LT, 1 and 5 yr post-LT renal function were calculated by Cockroft and modification of diet in renal disease (MDRD) formula. Since 1987 glomerular filtration rate (GFR) has been measured by radiolabeled tracers clearance (RTC). Risk factors for GFR < 50 mL/min were analyzed using a multivariate logistic regression model.', 'Mean pre-LT GFR was 79 and 85 mL/min with Cockroft and MDRD respectively; 11% of the patients had a GFR <or= 50 mL/min. 5 yr after LT, mean GFR was 63, 61 and 70 mL/min with MDRD, Cockroft and RTC respectively, GFR decreased by 26%, and 25% of the patients had a GFR < 50 mL/min. Independent risk factors associated with impaired renal function were: trough levels of cyclosporin A (CyA) >or= 150 microg/L or tacrolimus (FK) >or= 10 microg/L at 1 yr and CyA >or= 100 microg/L or FK >or= 8 microg/L at 5 yr.

Example Input: We aimed to investigate the anti-angiogenic properties of miR-155 via in vitro and in vivo studies.', 'miR-155 was knocked down using lentivirus-mediated RNA interference. The proliferation, migration, and tube formation of human retinal microvascular endothelial cells (HRMECs) were measured using BrdU, Transwell, and Matrigel assays, respectively. An oxygen-induced retinopathy (OIR) model was induced using neonatal C57BL/6J pups. Anti-miR-155 was intravitreally injected on postnatal day 12, and the retinal non-perfused areas and extent of neovascularization were measured on postnatal day 18 using transcardiovascular fluorescein isothiocyanate (FITC)-dextran perfusion and retina sections. A laser-induced choroidal neovascularization (CNV) model was induced in adult C57BL/6J mice. To evaluate the leakage areas, fundus fluorescein angiography was performed on day 14 after anti-miR-155 intravitreal injection. The neovascularization area of the CNV model was also examined in confocal and retina section studies. The expression levels of SHIP1 and p-Akt (Thr308, Ser473, and Thr450) were evaluated both in vitro and in vivo.', 'The expression of miR-155 was elevated in HRMECs after treatment with vascular endothelial growth factor (VEGF) and in neovascularized mouse model retinas. Anti-miR-155 lentivirus reduced the VEGF-induced proliferation, migration, and tube formation abilities of HRMECs. Anti-miR-155 attenuated retinal neovascularization in in vivo CNV and OIR models. In VEGF-treated HRMECs and retina neovascularization models, p-Akt (Ser473) was significantly upregulated, while SHIP1 was downregulated. Conversely, the inhibition of miR-155 restored the expression of SHIP1 and reduced the phosphorylation of effectors in the Akt (Ser473) signaling pathway.

Example Input: : Finding appropriate seed cells for bone tissue engineering remains a significant challenge. Considering that skin is the largest organ, we hypothesized that human bone morphogenetic protein receptor type IB (BmprIB)+ dermal cells could have enhanced osteogenic capacity in the healing of critical-sized calvarial defects in an immunodeficient mouse model. In this study, immunohistochemical staining revealed that BmprIB was expressed throughout reticular dermal cells; the positive expression rate of BmprIB was 3.5% 0.4% in freshly separated dermal cells, by flow cytometry. Furthermore, in vitro osteogenic capacity of BmprIB+ cells was confirmed by osteogenic-related staining and marker gene expression compared with unsorted dermal cells. In vivo osteogenic capacity was demonstrated by implantation of human BmprIB+ cell/coral constructs in the treatment of 4-mm diameter calvarial defects in an immunodeficient mouse model compared with implantation of unsorted cell/coral constructs and coral scaffold alone. These results indicate that the selective cell population BmprIB from human dermis is a promising osteogenic progenitor cell that can be a large-quantity and high-quality cell source for bone tissue engineering and regeneration.
