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".

[Q]: Abstract: We evaluated the levels and distribution of hypoxia in 31 human tumors using fluorescent immunohistochemical detection of binding by the 2-nitroimidazole, EF5. Hypoxia was found to be a heterogeneous property of human tumors. Necrosis was usually found adjacent to the highest level of binding in an individual patient's tumor. However, hypoxia often occurred without necrosis. In the group of tumors studied, the most common relationship between blood vessels (PECAM/CD31) and EF5 staining was consistent with diffusion-limited hypoxia; acute hypoxia occurred infrequently. Within a given patient's tumor, there was an inverse correlation between regions of proliferation (Ki-67) and regions of hypoxia. Again, however, when these parameters were examined in a group of patients, the absence of proliferation did not predict the presence of hypoxia. The relationships between hypoxia and other biologic endpoints are complex, but, within a given tumor's spatial relationships, they are in accord with known physiologic principles. Thus, our data emphasize that the relationships between hypoxia and other biologic parameters vary between patients. Necrosis, proliferation, and blood vessel distribution cannot predict the level or presence of hypoxia in an individual patient's tumor..

[Q]: Abstract: Long noncoding RNAs (IncRNAs) are increasingly implicated in cancer biology, contributing to essential cancer cell functions such as proliferation, invasion, and metastasis. In prostate cancer, several lncRNAs have been nominated as critical actors in disease pathogenesis. Among these, expression of PCGEM1 and PRNCR1 has been identified as a possible component in disease progression through the coordination of androgen receptor (AR) signaling (Yang et al., Nature 2013, see ref. [1]). However, concerns regarding the robustness of these findings have been suggested. Here, we sought to evaluate whether PCGEM1 and PRNCR1 are associated with prostate cancer. Through a comprehensive analysis of RNA-sequencing data (RNA-seq), we find evidence that PCGEM1 but not PRNCR1 is associated with prostate cancer. We employ a large cohort of >230 high-risk prostate cancer patients with long-term outcomes data to show that, in contrast to prior reports, neither gene is associated with poor patient outcomes. We further observe no evidence that PCGEM1 nor PRNCR1 interact with AR, and neither gene is a component of AR signaling. Thus, we conclusively demonstrate that PCGEM1 and PRNCR1 are not prognostic lncRNAs in prostate cancer and we refute suggestions that these lncRNAs interact in AR signaling..

[Q]: Abstract: We used bone marrow biopsies instead of mononuclear cells to maintain long-term cultures from 103 patients belonging to all five sub-categories of myelodysplastic syndromes (MDS), as well as 12 normal controls. By week 4, 30-50% confluency was reached and could be maintained for up to 12 weeks with 100% confluency. The four prominent cells were fibroblasts, macrophages, endothelial cells and adipocytes. Immunohistochemical and electron microscopic studies provided lineage confirmation. Normal hematopoiesis was well supported by MDS stroma. Neither the FAB nor cytogenetics was co-related with the potency of growth. MDS stroma appears to be both morphologically and functionally normal..
