instruction:
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.

BACKGROUND MicroRNAs (miRNAs) are small non-coding RNA molecules. Reduced or increased levels of specific miRNAs are observed in colon and other cancers, supporting their role in carcinogenesis. Detection of colorectal polyps is the cornerstone of the Bowel Cancer Screening Programme in the UK. However, uptake of screening nationally remains under 60%. We aimed to see whether circulating plasma miRNAs can be used to screen for patients with colorectal polyps, adenomas, or both.
METHODS Blood samples were taken from patients from the Bowel Cancer Screening Programme (asymptomatic but faecal occult blood testing [FOBt] positive). Plasma RNA was extracted, target miRNAs (19a, 98, 146b, 186, 191, 222*, 331-5p, 452, 625, 664, 1247) were identified on pooled case miRNA assay cards, and miRNA fraction was quantified by quantitative RT-PCR assay. Results were compared with endoscopy reports and with histology of any polyps identified and removed. Analysis was done with Excel (2011) and SPSS (version 20) software.
FINDINGS 210 patients were included (117 with polyps, 12 with cancer, 81 healthy controls [FOBt positive]). The miRNA panel showed significant differences in expression (on t testing) for patients compared with controls for those with polyps, cancer, or both (miR-19a, p=00184; miR-98, p=00206; miR-146b, p=00029; miR-186, p=00006; miR-62,5 p=00008), polyps (miR-19a, p=00233; miR-98, p=00224; miR-146b, p=0003; miR-186, p=00004; miR-625, p=0001), adenomas (miR-19a, p=00339; miR-98, p=00266; miR-146b, p=00045; miR-186, p=00008; miR-625, p=00049), multiple adenomas (both sides of colon; miR-146b, p=00194; miR-186, p=00226; miR-625, p=00013), and right-sided adenomas (miR-98, p=0031; miR-146b, p=00076; miR-186, p=00041; miR-331-5p, p=00142; miR-625, p=00049). Receiver operating characteristic analysis showed sensitivity of 60% or more, and specificity of 86% or more for men with polyps, men with adenomas, all patients with haemorrhoids or diverticulosis and polyps, and all patients with haemorrhoids or diverticulosis and adenomas.
INTERPRETATION The target miRNAs that we identified showed significant differences in expression levels for patients with polyps and patients with adenomas from controls. Use of this panel has potential as a screening test.

True

question:
Oncostatin M (OSM) and leukemia inhibitory factor (LIF) are members of the interleukin-6 (IL-6) subfamily of cytokines that use a common signal transducer gp130. Human OSM (hOSM) and LIF share a functional high-affinity receptor that is composed of gp130 and LIF receptor beta subunit (LIFRbeta). A second high-affinity receptor for hOSM was recently found to be formed by gp130 and the hOSM receptor beta subunit. However, the nature of murine OSM (mOSM) and its receptors has remained unknown. Using the recently cloned mOSM cDNA, we produced recombinant mOSM and studied its biological activity and receptor structure. Murine hematopoietic cell lines M1 and DA1.a, an embryonic stem cell line CCE, and Ba/F3 transfectants expressing gp130 and LIFRbeta responded to murine LIF (mLIF) and hOSM equally well, while these cells responded to mOSM only at a 30-fold to 100-fold higher concentration than those of mLIF and hOSM. In contrast, NIH3T3 cells responded to mOSM, but not to mLIF and hOSM. Scatchard plot analyses showed that mOSM bound to gp130 with low-affinity (kd = 2.8 to 4.2 nmol/L) and that the binding affinity did not increase in the presence of LIFRbeta. However, mOSM bound to NIH3T3 cells with high-affinity (kd = 660 pmol/L), whereas mLIF did not bind to NIH3T3 cells at all. These results indicate that unlike hOSM, mOSM and mLIF do not share the same functional receptor, and mOSM delivers signals only through its specific receptor complex. Further studies in mice will define the physiological roles of OSM.

False

question:
OBJECTIVE To review the literature on mental health and psychiatric morbidity in prison populations and relate findings to a Danish study on remand prisoners.
METHOD The literature is reviewed and subdivided in the following section: validity of psychometrics in prison populations, prevalence of psychiatric disorders prior to imprisonment, incidence of psychiatric disorders during imprisonment, psychopathy related to psychiatric comorbidity, dependence syndromes with special emphasis on different administrations of heroin use (smoke vs. injection). The results are compared with a longitudinal Danish study on remand prisoners in either solitary confinement (SC) or non-SC.
RESULTS Many factors must be taken into consideration when dealing with prisoners and mental health, e.g. international differences, the prison setting, demographics and methodological issues. The prison populations in general are increasing worldwide. Psychometrics may perform differently in prison populations compared with general populations with the General Health Questionnaire-28 having a low validity in remand prisoners. Psychiatric morbidity including schizophrenia is higher and perhaps increasing in prison populations compared with general populations with dependence syndromes being the most frequent disorders. The early phase of imprisonment is a vulnerable period with a moderately high incidence of adjustment disorders and twice the incidence in SC compared with non-SC. Prevalence of psychopathy is lower in European than North American prisons. Medium to high scores of psychopathy is related to higher psychiatric comorbidity. Opioid dependence is the most frequent drug disorder with subjects using injection representing a more dysfunctional group than subjects using smoke administration. Many mentally ill prisoners remain undetected and undertreated.
CONCLUSION There is a growing population of mentally ill prisoners being insufficiently detected and treated.
