Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Context: Central giant cell lesion (CGCL) and giant cell tumour (GCT) are bone lesions that share similar microscopic features. Recently, it was reported that 90% of bone GCT exhibit either p.Gly34 Trp or p.Gly34 Leu in H3F3A, one of two genes for histone H3.3 located on chromosome 1. We aimed to test whether sporadic CGCL of the jaws share the H3F3A mutations reported in GCT of other bones.', 'Nine samples of CGCL of the jaws were included in the study, and mutations were assessed by direct sequencing.', 'None of the CGCL samples presented the recurrent p.Gly34 Trp or p.Gly34 Leu mutations in the H3F3A gene.
Answer: On the basis of our findings, H3F3A p.Gly34 Trp or p.Gly34 Leu mutations are not a frequent event in CGCL. If these alterations are confirmed to be exclusive of GCT, the assessment of H3F3A mutations may help in the differential diagnosis of GCT and CGCL of the jaws.
Is the highly prevalent H3F3A mutation in giant cell tumours of bone shared by sporadic central giant cell lesion of the jaws?

Context: The aim of this study was to examine the utility of a hierarchical algorithm incorporating codes from the International Classification of Functioning, Disability and Health--ICF (WHO, 2001) and the International Statistical Classification of Diseases-ICD (WHO, 1994) to classify reasons for eligibility of young children in early intervention.', 'The database for this study was a nationally representative enrollment sample of more than 5,500 children in a longitudinal study of early intervention. Reasons for eligibility were reviewed and matched to the closest ICF or ICD codes under one of four major categories (Body Functions/Structures, Activities/Participation, Health Conditions, and Environmental Factors).', 'The average number of reasons for eligibility provided per child was 1.5, resulting in a population summary exceeding 100%. A total of 305 ICF and ICD codes were used with most (77%) of the children having codes in the category of Body Function/Structures. Forty-one percent of the sample had codes of Health Conditions, whereas the proportions with codes in the Activities/Partipication and Environmental Categories were 10 and 5%, respectively.
Answer: The results demonstrate that ICD and ICF can be jointly used as a common language to document disability characteristics of children in early intervention.
Do iCF and ICD codes provide a standard language of disability in young children?

Context: Toll-like receptor 4 (Tlr-4) mediates many biological effects of lipopolysaccharide (LPS), which has antitumoral effects on glioblastoma both in vivo and in vitro. However, the precise role of Tlr-4 in these antitumoral effects remains unknown.', 'The role of Tlr-4 in the antitumoral effect of LPS on glioblastomas was assessed in wild-type BALB/c mice and in Tlr-4 knockout (KO) BALB/c mice. Mice were implanted with DBT glioblastoma cells intracranially or subcutaneously, were treated with intratumoral LPS, and were assessed by histopathological examination for degrees of tumor progression and inflammation. Flow cytometry and Western blotting with antibodies to the Tlr-4 receptor and flow cytometry to the related CD14 moiety were performed to quantitate the expression levels of these two receptors by glioblastoma cells.', 'For subcutaneous tumors, LPS caused near complete tumor elimination in wild-type mice, but only a 50% reduction in Tlr-4 KO mice. For mice implanted with intracranial glioblastomas, LPS increased survival times modestly in wild-type mice, but showed no benefit in the Tlr-4 KO mice. There were no histological differences among wild-type and Tlr-4 KO mice, except for tumor size. In both models, an early neutrophilic and later macrophage-rich inflammatory infiltrate were seen after LPS administration. Quantitative flow cytometry and Western blotting showed no Tlr-4 receptor or CD14 expression in murine and human glioblastoma cells in vitro, and Western blotting suggested that Tlr-4 effects are mediated by nontumoral elements such as microglia and inflammatory cells.
Answer: LPS-induced antitumoral effects on glioblastoma multiforme are mediated, in part, by the Tlr-4 receptor. Further understanding of this process may lead to novel treatment strategies for this uniformly fatal disease.

Are the in vivo antitumoral effects of lipopolysaccharide against glioblastoma multiforme mediated in part by Toll-like receptor 4?
