Prognostic value of subventricular zone involvement in relation to tumor volumes defined by fused MRI and O-(2-[18F]fluoroethyl)-L-tyrosine (FET) PET imaging in glioblastoma multiforme

open access: yesRadiation Oncology, 2019
Background Subventricular zone (SVZ) involvement is associated with a dismal prognosis in patients with glioblastoma multiforme (GBM). Dual-time point (dtp) O-(2-[18F]fluoroethyl)-L-tyrosine (FET) PET/CT (PET) may be a time- and cost-effective ...

Target effects in negative-continuum assisted dielectronic recombination

open access: yes, 2015
The process of recombination of a quasi-free electron into a bound state of an initially bare nucleus with the simultaneous creation of a bound-electron--free-positron pair is investigated.

Early Radiation Therapy Response Assessment Using Multi‐Scale Photoacoustic Imaging

open access: yesAdvanced Science, EarlyView.
Tomographic and mesoscopic photoacoustics capture intratumoural features of radioresistance and response. ABSTRACT There is a critical unmet clinical need to identify biomarkers that predict and detect radiation therapy (RT) response in cancer. Using the unique capabilities of multi‐scale photoacoustic imaging (PAI) to depict tumor oxygenation and ...

Superiority of 18F-FNa PET/CT for Detecting Bone Metastases in Comparison with Other Diagnostic Imaging Modalities

open access: yesActa Médica Portuguesa, 2017
Introduction: The 18F-NaF positron emission tomography/computed tomography is being considered as an excellent imaging modality for bone metastases detection. This ability was compared with other imaging techniques.

Early Detection of Cell Death Using Transmembrane Water Exchange Magnetic Resonance Imaging

open access: yesAdvanced Science, EarlyView.
Cell death is important in both the development and treatment of cancer. In this study, it is demonstrated for the first time that a specific measurement of the transmembrane water exchange rate using magnetic resonance imaging can be used as an early marker of cell death in mammalian cells, in animals and in human patients. Abstract Cell death plays a

Morphological and functional alterations in type 2 diabetes pancreata assessed with MRI-based metrics and [18F]FP-(+)-DTBZ PET

open access: yesFrontiers in Endocrinology
ObjectiveTo determine if combining PET-derived beta-cell mass (BCM) estimates with MRI-based morphology metrics improves the prediction of beta-cell functional mass in type 2 diabetes (T2D).MethodsWe performed a retrospective analysis of 40 participants ...

SLC2A3‐Mediated Lactate Metabolism Promotes Lung Cancer Bone Metastasis by Modulating P53 Lactylation and Immune Evasion

open access: yesAdvanced Science, EarlyView.
SLC2A3 derived lactate promotes metastasis through p53 lactylation at K120 and osteoclast differentiation. Pharmacological inhibition of SLC2A3 upregulates PD‐1 expression on CD8+ T cells via lactate induced p53 lactylation, which modulates immune evasion. ABSTRACT Bone metastasis is a devastating consequence of lung cancer.
