Quantitative Diffusion and T2 Mapping Using RF‐Modulated Phase‐Based Gradient Echo Imaging

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 49-65, July 2026.
ABSTRACT Purpose To introduce and evaluate the feasibility of a novel RF‐phase modulated gradient echo (GRE) method for quantitative diffusion MRI, aimed at mitigating geometric distortion and enabling high‐resolution 3D quantitative diffusion/T2 mapping as a complementary alternative to conventional DWI.

Mass spectrometry proteomics for studying mitostasis

open access: yesProtein Science, Volume 35, Issue 7, July 2026.
Abstract Maintaining mitochondrial integrity and function is fundamental to cellular homeostasis. Cells rely on coordinated protein quality control (QC) systems—including intricate chaperone‐protease networks, the ubiquitin‐proteasome system, and cytosolic surveillance pathways—that together form a dynamic, cell‐wide mitostasis network governing the ...

A Constellation of Fluorescent Biosensors to Illuminate the Galaxy of Protein Kinases

open access: yesChemBioChem, Volume 27, Issue 11, 15 June 2026.
Protein kinases (PKs) are enzymes that catalyze phosphorylation of protein substrates involved in a wide variety of biological signalling pathways. This review describes the different families and mechanisms of action and regulation of protein kinases, together with the different classes of fluorescent biosensors that have been engineered and ...

Multi‐omics insights for deciphering prognosis‐related T cell subsets in hepatocellular carcinoma

open access: yesClinical and Translational Medicine, Volume 16, Issue 6, June 2026.
An integrated multi‐omics analysis delineates the prognostic landscape of T‐cell subsets in hepatocellular carcinoma. DPT cells and HBEGF‐related signals are associated with poor survival in hepatocellular carcinoma. Endothelial‐derived HBEGF recruits DPT cells, which in turn up‐regulate the EMT signatures and drive the migration of hepatocellular ...
