In this task, you are given a abstract of article and corresponding title of an article. Your task is to generate label "yes" if title is right for article, otherwise generate "no".

Input: Consider Input: Abstract: BACKGROUND Drug-eluting stent (DES) implantation is routine during coronary revascularization because DES significantly reduce rates of restenosis and target lesion revascularization compared with bare metal stent (BMS). However, available DES have limitations, such as late thrombosis because of delayed healing with poorer endothelialization and persistent local inflammation. Statins can inhibit cell proliferation, inflammation, and restore endothelial function. The present study evaluated the ability of stent-based cerivastatin delivery to reduce stent-induced inflammatory responses and adverse effects on endothelial function, and to inhibit neointimal hyperplasia in a porcine coronary model.
METHODS AND RESULTS Pigs were randomized into groups in which the coronary arteries (9 pigs, 18 coronaries in each group) had either a cerivastatin-eluting stent (CES) or a BMS. All animals survived without any adverse effects. Inflammatory cell infiltration evaluated using scanning electron microscopy on day 3 after stenting was significantly decreased in the treated vessels (inflammation score: 1.15+/-0.12 vs 2.43+/-0.34, p<0.0001). At day 28, endothelial function with intracoronary infusion of bradykinin was preserved in both the CES and BMS groups. Volumetric intravascular ultrasound images revealed decreased intimal volume in the CES group (28.3+/-5.4 vs 75.9+/-4.2 mm3, p<0.0001). Histomorphometric analysis showed reduced neointimal area (1.74+/-0.45 vs 3.83+/-0.51 mm2, p<0.0001) in the CES group despite similar injury scores (1.77+/-0.30 vs 1.77+/-0.22, p=0.97).
CONCLUSION In porcine coronary arteries CES significantly decreased neointimal hyperplasia with a decreased early inflammatory response and without endothelial dysfunction..

Input: Consider Input: Abstract: Ku70, a known nonhomologous end-joining (NHEJ) factor, also functions in tumor suppression, although this molecular mechanism remains uncharacterized. Previously, we showed that mice deficient for DNA ligase IV (Lig4), another key NHEJ factor, succumbed to aggressive lymphoma in the absence of tumor suppressor p53. However, the tumor phenotype is abrogated by the introduction of a hypomorphic mutant p53R172P, which impaired p53-mediated apoptosis but not cell-cycle arrest. However, Lig4/p53R172P mice succumbed to severe diabetes. To further elucidate the role of NHEJ and p53-mediated apoptosis in vivo, we bred Ku70/ p53R172P mice. Unexpectedly, these mice were free of diabetes, although 80% of the mutant mice had abnormally enlarged colons with pronounced inflammation. Remarkably, most of these mutant mice progressed to dysplasia, adenoma and adenocarcinoma; this is in contrast to the Lig4/p53R172P phenotype, strongly suggesting an NHEJ-independent function of Ku70. Significantly, our analyses of Ku70/p53R172P colonic epithelial cells show nuclear stabilization of -catenin accompanied by higher expression of cyclin D1 and c-Myc in affected colon sections than in control samples. This is not due to the p53 mutation, as Ku70/ mice share this phenotype. Our results not only unravel a novel function of Ku70 essential for colon homeostasis, but also establish an excellent in vivo model in which to study how chronic inflammation and abnormal cellular proliferation underlie tumorigenesis and tumor progression in the colon..

Input: Consider Input: Abstract: Recent studies suggest an association between attention-deficit/hyperactivity disorder (ADHD) and obesity. In this article, we systematically review and critically discuss evidence on the prevalence of ADHD in obese patients as well as the weight status of individuals with ADHD. Relevant articles were searched in PubMed, PsychInfo, and ISI Web of Science (January 1980 to June 2010). We found that current evidence indicates a high prevalence of ADHD in clinical samples of patients seeking treatment for their obesity. Moreover, available studies show that individuals with ADHD have higher-than-average body mass index z scores and/or a significantly higher prevalence of obesity compared with subjects without ADHD. Three mechanisms underlying the association between ADHD and obesity have been proposed: 1) it is possible that obesity and/or factors associated with it (such as sleep-disordered breathing) manifest as ADHD-like symptoms; 2) ADHD and obesity share common biological dysfunctions; and 3) ADHD contributes to obesity. With regards to the possible clinical implications, our findings suggest that it is noteworthy to screen for ADHD in patients with obesity and to look for abnormal eating behaviors as possible contributing factors of obesity in patients with ADHD. Based on preliminary findings, appropriate treatment of ADHD may improve the weight status of individuals with both obesity and ADHD..
