Chemosensitivity profiling of osteosarcoma tumour cell lines identifies a model of BRCAness.
(NATURE PORTFOLIO, 2018-07-13)Osteosarcoma (OS) is an aggressive sarcoma, where novel treatment approaches are required. Genomic studies suggest that a subset of OS, including OS tumour cell lines (TCLs), exhibit genomic loss of heterozygosity (LOH) ... -
Tumor to cervical spinal cord standardized uptake ratio (SUR) improves the reproducibility of <sup>18</sup>F-FDG-PET based tumor segmentation in head and neck squamous cell carcinoma in a multicenter setting.
(2019-01)Background In quantitative FDG-PET data analysis, normalization of the standardized uptake value (SUV) with an internal image-derived standard improves its reproducibility. In this study, the cervical spinal cord is proposed ... -
Capture Hi-C Library Generation and Analysis to Detect Chromatin Interactions.
(Wiley, 2018-07-06)Chromosome conformation capture (3C), coupled with next-generation sequencing (Hi-C), provides a means for deciphering not only the principles underlying genome folding and architecture, but more broadly, the role 3D ... -
Demonstration of correlations between clinical and physical image quality measures in chest and lumbar spine screen-film radiography
(BRITISH INST RADIOLOGY, 2001-06)The ability to predict clinical image quality from physical measures is useful for optimization in diagnostic radiology. In this work, clinical and physical assessments of image quality are compared and correlations between ... -
Kinetic energy of He atoms in liquid He-4-He-3 mixtures
(AMER PHYSICAL SOC, 2003-12)Deep inelastic neutron scattering measurements on liquid He-3-He-4 mixtures in the normal phase have been performed on the VESUVIO spectrometer at the ISIS pulsed neutron source at exchanged wave vectors of about qsimilar ... -
Nonperturbative real-space renormalization group scheme for the spin-1/2 XXX Heisenberg model
(AMER PHYSICAL SOC, 2001-11-01)In this paper we apply an analytical real-space renormalization group formulation which is based on numerical concepts of the density-matrix renormalization group, Within a rigorous mathematical framework we construct ... -
Psychosocial challenges and health-related quality of life of adolescents and young adults with hematologic malignancies.
(AMER SOC HEMATOLOGY, 2018-07-26)Adolescents and young adults (AYAs) occupy a unique place within the hematologic malignancy community due to the challenges they face related to their disease biology and physical, psychosocial, and economic circumstances, ... -
Desmoid fibromatosis through the patients' eyes: time to change the focus and organisation of care?
(SPRINGER, 2019-03-01)PURPOSE: Desmoid fibromatosis (DF) is a rare, unpredictable disease with no established, evidence-based treatments. Individual management is based on consensus algorithms. This study aimed to examine the specific health-related ... -
Identification and assessment of health-related quality of life issues in patients with sporadic desmoid-type fibromatosis: a literature review and focus group study.
(SPRINGER, 2018-12-01)PURPOSE: Sporadic desmoid-type fibromatosis (DTF) is a rare, chronic, non-metastasising, disease of the soft tissues. It is characterised by local invasive and unpredictable growth behaviour and a high propensity of local ... -
A comparison between cobalt and linear accelerator-based treatment plans for conformal and intensity-modulated radiotherapy
(BRITISH INST RADIOLOGY, 2008-04)The simplicity of cobalt units gives them the advantage ofreduced maintenance, running costs and downtime when compared with linear accelerators. However, treatments carried out on such units are typically limited to simple ... -
Imaging of testicular germ cell tumours.
(E-MED LTD, 2006-09-07)In testicular germ cell tumour (GCT), imaging plays a central role in assessment of tumour bulk, sites of metastases, monitoring response to therapy, surgical planning and accurate assessment of disease at relapse. The ... -
Genetic Variants in Epigenetic Pathways and Risks of Multiple Cancers in the GAME-ON Consortium.
(AMER ASSOC CANCER RESEARCH, 2017-06-01)Background: Epigenetic disturbances are crucial in cancer initiation, potentially with pleiotropic effects, and may be influenced by the genetic background.Methods: In a subsets (ASSET) meta-analytic approach, we investigated ... -
Epigenetic downregulation of human disabled homolog 2 switches TGF-beta from a tumor suppressor to a tumor promoter
(AMER SOC CLINICAL INVESTIGATION INC, 2010-08)The cytokine TGF-beta acts as a tumor suppressor in normal epithelial cells and during the early stages of tumorigenesis. During malignant progression, cancer cells can switch their response to TGF-beta and use this cytokine ... -
Texture analysis using proton density and T2 relaxation in patients with histological usual interstitial pneumonia (UIP) or nonspecific interstitial pneumonia (NSIP).
(PUBLIC LIBRARY SCIENCE, 2017-05-16)OBJECTIVES: The purpose of our study was to assess proton density (PD) and T2 relaxation time of usual interstitial pneumonia (UIP) and nonspecific interstitial pneumonia (NSIP) and to evaluate their utility in differentiating ... -
Line focus x-ray tubes-a new concept to produce high brilliance x-rays.
(IOP PUBLISHING LTD, 2017-10-27)Currently hard coherent x-ray radiation at high photon fluxes can only be produced with large and expensive radiation sources, such as 3[Formula: see text] generation synchrotrons. Especially in medicine, this limitation ... -
The shieldin complex mediates 53BP1-dependent DNA repair.
(NATURE PUBLISHING GROUP, 2018-08-02)53BP1 is a chromatin-binding protein that regulates the repair of DNA double-strand breaks by suppressing the nucleolytic resection of DNA termini1,2. This function of 53BP1 requires interactions with PTIP3 and RIF14-9, ... -
The Patient Deficit Model Overturned: a qualitative study of patients' perceptions of invitation to participate in a randomized controlled trial comparing selective bladder preservation against surgery in muscle invasive bladder cancer (SPARE, CRUK/07/011).
(2012-11-29)Background Evidence suggests that poor recruitment into clinical trials rests on a patient 'deficit' model - an inability to comprehend trial processes. Poor communication has also been cited as a possible barrier to ... -
