15O‐water PET‐detected myocardial ischaemia and CT‐derived FFR: Predicting the functional significance of anatomical stenosis

Clinical Physiology and Functional Imaging, Volume 46, Issue 6, November 2026.
Abstract Aims Coronary artery disease (CAD) is a major cause of morbidity and mortality worldwide. While coronary computed tomography angiography (CCTA) provides anatomical assessment of coronary stenoses, its ability to determine their functional significance is limited. Computed tomography‐derived fractional flow reserve (CT‐FFR) has emerged as a non‐

Rhenium‐Based β‐Galactosidase Probe Allows Senescence Profiling by Mass Cytometry

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
Senescence‐associated β‐galactosidase (SA‐β‐Gal) activity is a widely accepted biomarker of cellular senescence, yet its integration with other senescence markers has been limited by available detection methods. Here, we introduce ReGal, a mass cytometry‐compatible SA‐β‐Gal activity probe that can be multiplexed with established markers of senescence ...

Inferior Frontal Gyrus Alterations in Freezing of Gait in Parkinson's Disease Without Evidence for Overall Hemispheric Lateralization: A Systematic Review and Activation Likelihood Estimation Meta‐Analysis

European Journal of Neuroscience, Volume 64, Issue 9, November 2026.
Our systematic review included 108 neuroimaging articles examining freezing of gait in Parkinson's disease, with 33 included in the primary activation likelihood estimation meta‐analysis. We assessed spatial convergence and hemispheric lateralization of reported abnormalities, identifying the right inferior frontal gyrus as the main convergent region ...

Coupling between global brain blood oxygen level‐dependent activity and cerebrospinal fluid dynamics in young endurance athletes

Experimental Physiology, Volume 111, Issue 11, Page 5219-5235, 1 November 2026.
Abstract Cerebrospinal fluid (CSF) contributes to brain waste clearance through its coupling with cerebral haemodynamics. Aerobic exercise promotes brain health, but its influence on brain waste clearance remains unclear. This study examined the coupling between CSF and cerebral haemodynamics in endurance athletes. Fifteen young male endurance athletes

Systematic Optimization of an SLE‐DAPTAD LC–MS/MS Workflow for Simultaneous Quantification of Low‐Abundance Vitamin D3 Metabolites in Plasma

Rapid Communications in Mass Spectrometry, Volume 40, Issue 20, 30 October 2026.
ABSTRACT Rationale Liquid chromatography–tandem mass spectrometry (LC–MS/MS) analysis of vitamin D3 metabolites is analytically challenging because these compounds are structurally similar, strongly matrix‐associated, and have poor ionization efficiency.
