Deep Learning Enables Individual Xenograft Cell Classification in Histological Images by Analysis of Contextual Features.
(SPRINGER/PLENUM PUBLISHERS, 2021-06-01)Patient-Derived Xenografts (PDXs) are the preclinical models which best recapitulate inter- and intra-patient complexity of human breast malignancies, and are also emerging as useful tools to study the normal breast ... -
Deep Learning Framework with Multi-Head Dilated Encoders for Enhanced Segmentation of Cervical Cancer on Multiparametric Magnetic Resonance Imaging.
(MDPI, 2023-11-03)T2-weighted magnetic resonance imaging (MRI) and diffusion-weighted imaging (DWI) are essential components of cervical cancer diagnosis. However, combining these channels for the training of deep learning models is challenging ... -
Deep learning how to fit an intravoxel incoherent motion model to diffusion-weighted MRI.
(WILEY, 2020-01-01)PURPOSE: This prospective clinical study assesses the feasibility of training a deep neural network (DNN) for intravoxel incoherent motion (IVIM) model fitting to diffusion-weighted MRI (DW-MRI) data and evaluates its ... -
Deep sequencing reveals persistence of cell-associated mumps vaccine virus in chronic encephalitis.
(2017-01)Routine childhood vaccination against measles, mumps and rubella has virtually abolished virus-related morbidity and mortality. Notwithstanding this, we describe here devastating neurological complications associated with ... -
Deep-learned estimation of uncertainty in measurements of apparent diffusion coefficient from whole-body diffusion-weighted MRI.
(PERGAMON-ELSEVIER SCIENCE LTD, 2022-10-01)PURPOSE: To use deep learning to calculate the uncertainty in apparent diffusion coefficient (σADC) voxel-wise measurements to clinically impact the monitoring of treatment response and improve the quality of ADC maps. ... -
Defective ALC1 nucleosome remodeling confers PARPi sensitization and synthetic lethality with HRD.
(CELL PRESS, 2021-02-18)Chromatin is a barrier to efficient DNA repair, as it hinders access and processing of certain DNA lesions. ALC1/CHD1L is a nucleosome-remodeling enzyme that responds to DNA damage, but its precise function in DNA repair ... -
Deficiency of LKB1 in heart prevents ischemia-mediated activation of AMPK alpha 2 but not AMPK alpha 1
(2006-05)Deficiency of LKB1 in heart prevents ischemia-mediated activation of AMPK alpha 2 but not AMPK alpha 1 Recent studies indicate that the LKB1 is a key regulator of the AMP-activated protein kinase ( AMPK), which plays a ... -
Deficient adaptation to centrosome duplication defects in neural progenitors causes microcephaly and subcortical heterotopias.
(AMER SOC CLINICAL INVESTIGATION INC, 2021-08-23)Congenital microcephaly (MCPH) is a neurodevelopmental disease associated with mutations in genes encoding proteins involved in centrosomal and chromosomal dynamics during mitosis. Detailed MCPH pathogenesis at the cellular ... -
Defining a New Prognostic Index for Stage I Nonseminomatous Germ Cell Tumors Using CXCL12 Expression and Proportion of Embryonal Carcinoma.
(AMER ASSOC CANCER RESEARCH, 2016-03-01)PURPOSE: Up to 50% of patients diagnosed with stage I nonseminomatous germ cell tumors (NSGCTs) harbor occult metastases. Patients are managed by surveillance with chemotherapy at relapse or adjuvant treatment up front. ... -
Defining aggressive or early progressing nononcogene-addicted non-small-cell lung cancer: a separate disease entity?
(2019-04)A substantial proportion of patients with nononcogene-addicted non-small-cell lung cancer (NSCLC) has 'aggressive disease', as reflected in short time to progression or lack of disease control with initial platinum-based ... -
Defining novel immune biomarkers of prognosis and immunotherapy sensitivity in gastro-oesophageal and colorectal cancers
(Institute of Cancer Research (University Of London), 2023-11-28)Background Gastro-oesophageal adenocarcinomas (GOAs) frequently recur after resection; prognostic and predictive markers are absent. Mismatch repair-deficient (MMRd) GOAs have high mutational burden, are frequently ... -
Defining Signatures of Arm-Wise Copy Number Change and Their Associated Drivers in Kidney Cancers.
(MDPI, 2019-11-16)Using pan-cancer data from The Cancer Genome Atlas (TCGA), we investigated how patterns in copy number alterations in cancer cells vary both by tissue type and as a function of genetic alteration. We find that patterns in ... -
Defining the mechanisms of multi-target tyrosine kinase inhibitor resistance in soft tissue sarcoma
Soft tissue sarcomas (STS) are a rare, heterogeneous, and challenging group of cancers to treat effectively. The approval of pazopanib, as well as promising clinical trial data for a number of other multi-target tyrosine ... -
Defining the role of SF3B1K700E mutations in ER+ breast cancer
(Institute of Cancer Research (University Of London), 2021-09-30)Mutations in SF3B1, a component of the RNA splicing machinery, underpin a number of aggressive cancers. Hotspot mutations in SF3B1 are present in around 3% of breast cancers, are enriched in oestrogen receptor positive ... -
