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 ... -
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 ... -
EGFR signaling in invasion, angiogenesis and metastasis
(Humana Press, 2008-09-25)Tumour invasion and metastasis are the hallmarks of advanced stage cancer and are associated with poor patient prognosis. EGFR is overexpressed in a variety of tumour types and this frequently correlates with a more ... -
Endovaginal magnetic resonance imaging of stage 1A/1B cervical cancer with A T2- and diffusion-weighted magnetic resonance technique: effect of lesion size and previous cone biopsy on tumor detectability.
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2011-03-01)OBJECTIVE: To evaluate the effects of previous cone biopsy and lesion size on detectability of stage 1a/1b cervical cancer using endovaginal T2- and diffusion-weighted magnetic resonance imaging. METHODS: One hundred and ... -
A risk prediction algorithm based on family history and common genetic variants: application to prostate cancer with potential clinical impact.
(WILEY, 2011-07-18)Genome wide association studies have identified several single nucleotide polymorphisms (SNPs) that are independently associated with small increments in risk of prostate cancer, opening up the possibility for using such ... -
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 ... -
Do imaging biomarkers relate to outcome in patients treated with VEGF inhibitors?
(AMER ASSOC CANCER RESEARCH, 2012-12-15)The management of solid tumors has been transformed by the advent of VEGF pathway inhibitors. Early clinical evaluation of these drugs has used pharmacodynamic biomarkers derived from advanced imaging such as dynamic MRI, ... -
Assessment of the robustness of volumetric-modulated arc therapy for lung radiotherapy
(Oxford University Press (OUP), 2013-03-01)Volumetric-modulated arc therapy (VMAT) is increasingly popular as a treatment method in radiotherapy owing to the speed with which treatments can be delivered. However, there has been little investigation into the effect ... -
Beam modeling and VMAT performance with the Agility 160-leaf multileaf collimator.
(2013-05-06)The Agility multileaf collimator (Elekta AB, Stockholm, Sweden) has 160 leaves of projected width 0.5 cm at the isocenter, with maximum leaf speed 3.5 cms-1. These characteristics promise to facilitate fast and accurate ... -
Identification of nine new susceptibility loci for testicular cancer, including variants near DAZL and PRDM14.
(NATURE PUBLISHING GROUP, 2013-06-01)Testicular germ cell tumor (TGCT) is the most common cancer in young men and is notable for its high familial risks. So far, six loci associated with TGCT have been reported. From genome-wide association study (GWAS) ... -
Individualized 131I-mIBG therapy in the management of refractory and relapsed neuroblastoma.
(SPRINGER, 2013-10-01)OBJECTIVE: Iodine-131-labelled meta-iodobenzylguanidine (I-mIBG) therapy is an established treatment modality for relapsed/refractory neuroblastoma, most frequently administered according to fixed or weight-based criteria. ... -
Tumor-Secreted LOXL2 Activates Fibroblasts through FAK Signaling
(AMER ASSOC CANCER RESEARCH, 2013-11-01)Cancer-associated fibroblasts enhance cancer progression when activated by tumor cells through mechanisms not yet fully understood. Blocking mammary tumor cell-derived lysyl oxidase-like 2 (LOXL2) significantly inhibited ... -
Chemical- and radiation-induced haemorrhagic cystitis: current treatments and challenges.
(WILEY, 2013-11-01)• To review the published data on predisposing risk factors for cancer treatment-induced haemorrhagic cystitis (HC) and the evidence for the different preventive and therapeutic measures that have been used in order to ... -
Comparison of three reference methods for the measurement of intracellular pH using 31P MRS in healthy volunteers and patients with lymphoma.
(WILEY-BLACKWELL, 2014-02-01)31P magnetic resonance spectroscopy (31P MRS) can measure intracellular pH (pHi) using the chemical shift difference between pH-dependent inorganic phosphate (Pi) and a pH-independent reference peak. This study compared ... -
Focal amplification of the androgen receptor gene in hormone-naive human prostate cancer
(NATURE PUBLISHING GROUP, 2014-03-18)Background: Androgen receptor (AR)-gene amplification, found in 20-30% of castration-resistant prostate cancer (CRPCa) is proposed to develop as a consequence of hormone-deprivation therapy and be a prime cause of treatment ... -
Intrinsic susceptibility MRI identifies tumors with ALKF1174L mutation in genetically-engineered murine models of high-risk neuroblastoma.
(PUBLIC LIBRARY SCIENCE, 2014-03-25)The early identification of children presenting ALK(F1174L)-mutated neuroblastoma, which are associated with resistance to the promising ALK inhibitor crizotinib and a marked poorer prognosis, has become a clinical priority. ... -
