In this task, you are given an abstract of article. Your task is to generate label "True" if abstract is structured, otherwise generate "False". A structured abstract is composed of a topic sentence (or key sentence), relevant supporting sentences, and a closing (or transition) sentence. This structure is key to keeping your abstract focused on the main idea and creating a clear and concise image.

Question: BACKGROUND Cerebellar glioblastoma multiforme (cGBM) is rare, and although there is a general belief that these tumors have a worse prognosis than supratentorial GBM (sGBM), few studies have been published to support this belief.
OBJECTIVE To investigate the effect of cerebellar location on survival through a case-control design comparing overall survival time of cGBM and sGBM patients.
METHODS The Surveillance, Epidemiology, and End Results (SEER) registry was used to identify 132 patients with cGBM (1973-2008). Each cGBM patient was matched with an sGBM patient from among 20,848 sGBM patients on the basis of age, extent of resection, decade of diagnosis, and radiation therapy using propensity score matching.
RESULTS Within the cGBM, 37% were older than 65 years of age, 62% were men, and 87% were white. Most patients underwent surgery and radiation (74%), whereas only 26% underwent surgical resection only. The median survival time for the cGBM and sGBM matched cohort was 8 months; however, the survival distributions differed (log-rank P = .04). Survival time for cGBM vs sGBM at 2 years was 21.5% vs 8.0%, and 12.7% vs 5.3% at 3 years. Multivariate analysis of survival among cGBM patients showed that younger age (P < .0001) and having radiation therapy (P < .0001) were significantly associated with reduced hazard of mortality. Among all patients, multivariate analysis showed that tumor location (P = .03), age (P < .0001), tumor size (P = .009), radiation (P < .0001), and resection (P < .0001) were associated with survival time in the unmatched cohort.
CONCLUSION Median survival time for cGBM and sGBM patients was 8 months, but cGBM patients had a survival time advantage as the study progressed. These findings suggest that cGBM patients should be treated as aggressively as sGBM patients with surgical resection and radiation therapy.

Answer: True

Question: MOTIVATION The nucleosome is the basic repeating unit of chromatin. It contains two copies each of the four core histones H2A, H2B, H3 and H4 and about 147 bp of DNA. The residues of the histone proteins are subject to numerous post-translational modifications, such as methylation or acetylation. Chromatin immunoprecipitiation followed by sequencing (ChIP-seq) is a technique that provides genome-wide occupancy data of these modified histone proteins, and it requires appropriate computational methods.
RESULTS We present NucHunter, an algorithm that uses the data from ChIP-seq experiments directed against many histone modifications to infer positioned nucleosomes. NucHunter annotates each of these nucleosomes with the intensities of the histone modifications. We demonstrate that these annotations can be used to infer nucleosomal states with distinct correlations to underlying genomic features and chromatin-related processes, such as transcriptional start sites, enhancers, elongation by RNA polymerase II and chromatin-mediated repression. Thus, NucHunter is a versatile tool that can be used to predict positioned nucleosomes from a panel of histone modification ChIP-seq experiments and infer distinct histone modification patterns associated to different chromatin states. AVAILABILITY The software is available at http://epigen.molgen.mpg.de/nuchunter/.

Answer: True

Question: Uncontrolled proteolysis by neutrophil serine proteases (NSPs) in lung secretions is a hallmark of cystic fibrosis (CF). We have shown that the active neutrophil elastase, protease 3, and cathepsin G in CF sputum resist inhibition in part by exogenous protease inhibitors. This resistance may be due to their binding to neutrophil extracellular traps (NETs) secreted by the activated neutrophils in CF sputum and to genomic DNA released from senescent and dead neutrophils. Treating CF sputum with DNase dramatically increases its elastase activity, which can then be stoichiometrically inhibited by exogenous elastase inhibitors. However, DNase treatment does not increase the activities of protease 3 and cathepsin G, indicating their different distribution and/or binding in CF sputum. Purified blood neutrophils secrete NETs when stimulated by the opportunistic CF bacteria Pseudomonas aeruginosa and Staphylococcus aureus. The activities of the three proteases were unchanged in these conditions, but subsequent DNase treatment produced a dramatic increase in all three proteolytic activities. Neutrophils activated with a calcium ionophore did not secrete NETs but released huge amounts of active proteases whose activities were not modified by DNase. We conclude that NETs are reservoirs of active proteases that protect them from inhibition and maintain them in a rapidly mobilizable status. Combining the effects of protease inhibitors with that of DNA-degrading agents could counter the deleterious proteolytic effects of NSPs in CF lung secretions.
