Predictive value of baseline metabolic tumor burden on 18F-FDG PET/CT for brain metastases in patients with locally advanced non-small-cell lung cancer

Frontiers in Oncology, 2022
ObjectivesBrain metastases (BMs) are a major cause leading to the failure of treatment management for non-small-cell lung cancer (NSCLC) patients. The purpose of this study was to evaluate the predictive value of baseline metabolic tumor burden on 18F ...

PET/CT-based radiomics analysis may help to predict neoadjuvant chemotherapy outcomes in breast cancer

Frontiers in Oncology, 2022
BackgroundThe aim of this study was to evaluate the clinical usefulness of radiomics signature-derived 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography–computed tomography (PET-CT) for the early prediction of neoadjuvant chemotherapy (NAC ...

Nicotinamide adenine dinucleotide reduced (NADH) is a natural UV filter of certain bird lens

Scientific Reports, 2022
In this work, we for the first time report the identification of UV filters in the bird eye lens. We found that lenses of some raptors (black kite, common buzzard) and waterfowl (birds from Podicipedidae family) contain unusually high levels of reduced ...

Non-contrast quantitative study of brain perfusion changes in multiple sclerosis [PDF]

Digital Diagnostics
BACKGROUND: Non-contrast magnetic resonance perfusion can identify areas of cerebral perfusion changes in patients with multiple sclerosis, even in the absence of focal lesions [1]. This technique offers several advantages, including non-invasiveness [2]
