Summary Background Magnetic resonance elastography (MRE) is a reliable non‐invasive alternative to liver biopsy for assessing fibrosis. There are limited data regarding an association between fibrosis by MRE and risk of cardiovascular disease (CVD). Aim To investigate the high‐risk CVD phenotype determined coronary artery calcification (CAC) with in patients non‐alcoholic fatty (NAFLD).

Abstract Folate is essential for nucleotide synthesis, DNA replication, and methyl group supply. Low-folate status has been associated with increased risks of several cancer types, suggesting a chemopreventive role folate. However, recent findings on giving folic acid to patients history colorectal polyps raise concerns about the efficacy safety folate supplementation long-term health effects fortification. Results suggest that undetected precursor lesions may progress under supplementation,...

Abstract Background: Endogenous retrotransposable elements (EREs) can modulate antitumor immune responses via viral mimicry response. We previously described an association between ERE upregulation and radiological response to checkpoint blockade (ICB) in advanced solid tumors the phase II INSPIRE trial (NCT02644369) (ASCO 2024). Here, we validate of EREs ICB two independent cohorts patients (pts) with melanoma non-small cell lung cancer (NSCLC) treated ICB. Methods: Publicly available...

Abstract Low-folate status and genetic polymorphisms in folate metabolism have been linked to several cancers. Possible biological mechanisms for this association include effects on purine thymidine synthesis, DNA methylation, or homocysteine concentrations. The influence of variation these putative biomarkers cancer risk has largely unexplored. We used a mathematical model that simulates biochemistry predict (a) the with defined enzyme function (MTHFR TS) (b) potential,...

Three-dimensional (3D) tissue models such as epithelial spheroids or organoids have become popular for pre-clinical drug studies. In contrast to 2D monolayer culture, the characterization of 3D from non-invasive brightfield images is a significant challenge. To address this issue, here we report deep-learning uncovered measurement networks (Deep-LUMEN) assay. Deep-LUMEN an object detection algorithm that has been fine-tuned automatically uncover subtle differences in spheroid morphology...
