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.

To investigate the effect of 1,25-dihydroxyvitamin D3 (1,25VD3) on house dust mites (HDM)-induced expression of thymic stromal lymphopoietin (TSLP) in human airway epithelial cells in vitro.', 'Human airway epithelial 16HBE cells were incubated with 200, 400, and 800 U/L in the absence or presence of 1,25VD3 (10(-8) mol/L) for 6 h and 24 h, and TSLP mRNA and protein expressions in the cells were assessed using quantitative PCR and ELISA.', '16HBE cells incubated with HDM at 200, 400, and 800 U/L showed significantly increased TSLP mRNA and protein expressions (P<0.05). Pretreatment of the cells with 1,25VD3 obviously lowered 400 U/L HDM-induced TSLP expressions (P<0.05), but 1,25VD3 added along with HDM in the cells did not produce significant effects on TSLP expressions (P=0.58).

Anxiety disorders increase risk of future cardiovascular disease (CVD) and mortality, even after controlling for confounds including smoking, lifestyle, and socioeconomic status, and irrespective of a history of medical disorders. While impaired vagal function, indicated by reductions in heart rate variability (HRV), may be one mechanism linking anxiety disorders to CVD, prior studies have reported inconsistent findings highlighting the need for meta-analysis.', 'Studies comparing resting-state HRV recordings in patients with an anxiety disorder as a primary diagnosis and healthy controls were considered for meta-analysis.', "Meta-analyses were based on 36 articles, including 2086 patients with an anxiety disorder and 2294 controls. Overall, anxiety disorders were characterized by lower HRV [high frequency (HF): Hedges' g\u2009=\u2009-0.29. 95% CI: -0.41 to -0.17, p\u2009<\u20090.001; time domain: Hedges' g\u2009=\u2009-0.45, 95% CI: -0.57 to -0.33, p\u2009<\u20090.001] than controls. Panic disorder (n\u2009=\u2009447), post-traumatic stress disorder (n\u2009=\u2009192), generalized anxiety disorder (n\u2009=\u200968), and social anxiety disorder (n\u2009=\u200990), but not obsessive-compulsive disorder (n\u2009=\u200940), displayed reductions in HF HRV relative to controls (all ps\u2009<\u20090.001).

Ex Input:
To investigate serum levels of the advanced glycation end-products (AGEs) pentosidine and N epsilon-carboxymethyllysine (CML) in patients classified into different osteoporosis subgroups according to histomorphometric data.', 'Serum samples were obtained from 116 osteoporotic patients (34 men, 82 women) classified by bone histomorphometry into subgroups with high turnover (HTO, n = 32), low turnover (LTO, n = 39), normal turnover (NTO, n = 9) and cellular uncoupled osteoporosis (CUO, n = 36). Pentosidine was measured by high-performance liquid chromatography, and CML by a competitive enzyme-linked immunoassay.', 'The entire osteoporosis group had significantly higher pentosidine and CML serum concentrations than healthy subjects. In contrast to healthy subjects, no correlation between levels of AGEs and age could be found. In subgroups characterized by increased bone resorption (HTO, CUO), serum pentosidine correlated significantly with the histomorphometric marker reflecting osteoclast activity/bone resorption (eroded surface as a percentage of trabecular surface). Moreover, in CUO a strong correlation between pentosidine and the mineral apposition rate was found. Surprisingly, in HTO the levels of CML and percentage of eroded surface were significantly negatively correlated.
