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".

Example Input: Abstract: OBJECTIVE Ankylosing spondylitis (AS) and spondyloarthropathy (SpA) are inflammatory diseases of unknown etiology. Various exogenous and endogenous (inherited) factors play a role in their development. Sulfasalazine (SSZ) is generally accepted as a disease modifying drug in the treatment of AS and SpA. Which part of SSZ, 5-acetylsalicylic acid (5-ASA, mesalazine) or sulfapyridine (SP), is the effective moiety is unknown. As the bowel, colon, and the ileum play an important role in the development of AS and SpA, it may be possible that 5-ASA is the effective moiety, with a similar mode of action as in the treatment of inflammatory bowel disease. To determine the efficacy of 5-ASA an open pilot study was done in 2 groups of patients with SpA. METHODS Twenty patients with SpA, who were taking SSZ, were switched to 5-ASA (Pentasa), and 19 patients with active SpA were treated with 5-ASA without previous administration of SSZ.
RESULTS In the first group, 17 (85%) patients responded with respect to the physician global clinical assessment compared to the previous SSZ treatment period; whereas in the second patient group a statistically significant improvement was obtained in erythrocyte sedimentation rate.
CONCLUSION The results support our hypothesis that 5-ASA might be the active moiety of SSZ in the treatment of SpA.. Title: Treatment of spondyloarthropathy with 5-aminosalicylic acid (mesalazine): an open trial.

Example Input: Abstract: Lung cancer is the leading cause of cancer-related mortality in humans worldwide. Moreover, the overall 5-year survival rate is only 15%. Pathologically almost 80% of all lung cancer cases are non-small cell lung cancer (NSCLC). Cancer-associated fibroblasts (CAFs) have been found to exist in a large number of NSCLCs. CAFs have been proven to promote tumor progression, metastasis and resistance to therapy through paracrine effects in most solid tumors. In the present study, firstly we isolated CAFs from patient tissues and demonstrated that they promoted cell proliferation and chemoresistance to cisplatin in the lung cancer cell lines A549 and 95D in a paracrine manner. Secondly, using ELISA and quantative PCR, we found that a higher amount of stromal cell-derived factor 1 (SDF-1) existed in the CAFs rather than that observed in the normal fibroblasts (NFs). Thirdly, we detected that SDF-1 facilitated lung cancer cell proliferation and drug resistance via the CXCR4-mediated signaling pathway which involved NF-B and Bcl-xL. Moreover, we also confirmed that the expression level of SDF-1 in the CAFs was negatively regulated by microRNA mir-1 through microRNA overexpression and quantitative PCR. Overall, our data provide one explanation for the effects of CAFs on lung cancer cells. Meanwhile, our results also suggest CAFs as a potential therapeutic target in tumor treatment..

Example Input: Abstract: When the food intake of organisms such as yeast and rodents is reduced (dietary restriction), they live longer than organisms fed a normal diet. A similar effect is seen when the activity of nutrient-sensing pathways is reduced by mutations or chemical inhibitors. In rodents, both dietary restriction and decreased nutrient-sensing pathway activity can lower the incidence of age-related loss of function and disease, including tumors and neurodegeneration. Dietary restriction also increases life span and protects against diabetes, cancer, and cardiovascular disease in rhesus monkeys, and in humans it causes changes that protect against these age-related pathologies. Tumors and diabetes are also uncommon in humans with mutations in the growth hormone receptor, and natural genetic variants in nutrient-sensing pathways are associated with increased human life span. Dietary restriction and reduced activity of nutrient-sensing pathways may thus slow aging by similar mechanisms, which have been conserved during evolution. We discuss these findings and their potential application to prevention of age-related disease and promotion of healthy aging in humans, and the challenge of possible negative side effects..
