Radiomics Analysis of Contrast-Enhanced CT Predicts Survival in Clear Cell Renal Cell Carcinoma

Frontiers in Oncology, 2021
PurposeTo develop and validate the radiomics nomogram that combines clinical factors and radiomics features to estimate overall survival (OS) in patients with clear cell renal cell carcinoma (ccRCC), and assess the incremental value of radiomics for OS ...

Correlative Tomography [PDF]

Scientific Reports, 2014
Increasingly researchers are looking to bring together perspectives across multiple scales, or to combine insights from different techniques, for the same region of interest. To this end, correlative microscopy has already yielded substantial new insights in two dimensions (2D).

Dysregulation of the Sirt5/IDH2 axis contributes to sunitinib resistance in human renal cancer cells

FEBS Open Bio, 2021
Sunitinib (Sun), a tyrosine kinase inhibitor of vascular endothelial growth factor receptor, is the standard first‐line treatment against advanced clear cell renal cell carcinoma (RCC), but resistance to therapy is inevitable.

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 ...

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 ...

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 ...
