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.

Previous research in fetuses with increased nuchal translucency (NT) showed abnormal lymphatic endothelial differentiation characteristics, including increased vascular endothelial growth factor (VEGF)-A expression, and aberrant smooth muscle cells (SMCs) surrounding enlarged jugular lymphatic sacs (JLS). We hypothesized that abnormal Sonic hedgehog (Shh) expression would result in altered VEGF-A signaling in the lymphatic endothelial cells of the JLS and that aberrant acquisition of SMCs could be caused by downregulation of forkhead transcription factor FOXC2 and upregulation of platelet-derived growth factor (PDGF)-B in the lymphatic endothelial cells of the JLS.', 'Five trisomy 21 fetuses and four controls were investigated using immunohistochemistry for Shh, VEGF-A, FOXC2 and PDGF-B expression in the lymphatic endothelial cells of the JLS.', 'An increased Shh, VEGF-A and PDGF-B expression, and decreased FOXC2 expression were shown in the lymphatic endothelial cells of the JLS of the trisomic fetuses.

Acute kidney injury (AKI) is an established indicator of all-cause mortality in a coronary care unit (CCU), and evaluating the risks of renal dysfunction can guide treatment decisions. In this study we used the Society of Thoracic Surgeons (STS) score to predict the incidence of AKI in CCU patients who had not undergone coronary artery bypass surgery (CABG) after a cardiac angiogram.', 'The study cohort comprised 126 patients diagnosed with 2 or 3 coronary vessels disease who did not receive CABG during their hospital course. This study was performed in the CCU of a tertiary referral university hospital between September 2012 and August 2013. The STS score was evaluated with adjustment in all patients and the outcomes of the risk of mortality, morbidity, or mortality and renal failure were selected for predicting assessment. Furthermore, the performance of the STS scores was compared with that of other scoring systems.', 'A total of 28.5% (36 of 126) of the patients had AKI of varying severity. For predicting AKI, the STS renal failure score was excellent, with areas under the receiver operating characteristic curve of 0.851 ± 0.039, p < 0.001. When compared with other scoring systems, the STS renal failure score demonstrated the highest discriminatory power, the most favorable Youden index, and the highest overall correctness of prediction.

Korean red ginseng (ginseng, Panax ginseng C.A. Meyer) has traditionally been used in the treatment of most ageing-related diseases, such as obesity, diabetes, and dyslipidemia, but the mechanism of the effects is unclear. The aim of this study was to determine the effects of ginseng on obesity in a mouse model of female obesity (obese female db/db mouse) and to investigate the mechanism of anti-obesity effects.', 'After female db/db (B6.Cg-m Lepr(db)/++/J) mice were treated with 5% (w/w) ginseng for 13 weeks, variables and parameters of obesity and disorders related to obesity were examined. Blood vessel density and the expression of genes involved in angiogenesis were also measured.', 'Mice treated with ginseng for 13 weeks had less body weight and lower adipose tissue mass compared to control, untreated mice. The size of adipocytes was smaller in visceral adipose tissues of ginseng-treated mice. Obesity-related complications, such as hepatic steatosis, hypertriglyceridemia, and hyperglycemia, were markedly improved in treated mice. Blood vessel density was lower in visceral adipose tissue sections from treated mice than those from control mice. Concomitantly, mRNA levels for VEGF-A and FGF-2 were lower in both visceral adipose tissue from treated mice and treated 3T3-L1 cells compared to those from untreated controls. Protein levels for VEGF were also lower in visceral adipose tissue from treated mice. In contrast, ginseng increased mRNA expression of genes responsible for energy expenditure and fatty acid β-oxidation in visceral adipose tissue during ginseng-induced weight reduction.
