Spatial Transcriptional Heterogeneity in the Infarct Core and Its Surrounding Regions Targeting Piezo1 Signals in Rats With Myocardial Ischemia‐Reperfusion Injury

MedComm, Volume 7, Issue 1, January 2026.
We employed spatially resolved transcriptomics to visualize and molecularly characterize the spatial distribution of gene expression profiles in the rats’ left ventricles following MIR injury. Further experiments indicated that cardiogenic Piezo1‐mediated calcium overload exacerbates MIR through the activation of matrix metalloproteinase 2‐ryanodine ...

Lycopene's Role in Mitigating Obesity‐Induced Cardiac Remodeling: Insights Into Inflammatory and MMP‐2 Pathways

Molecular Nutrition &Food Research, Volume 70, Issue 2, 29 January 2026.
A. Consumption of a highsugar‐fat diet causes excess nutrients, hypertrophy and hyperplasia of adipocytes, causing obesity. Obesity leads to increased inflammatory levels in the heart, which stimulates greater activation of Metalloproteinase‐2 (MMP‐2), which has collagenolytic activity, degrading the collagen network in the heart, ultimately causing ...

Contrast‐Enhanced 3T Vessel Wall Imaging for Symptomatic Intracranial Atherosclerotic Stenosis: Value of Pituitary Stalk Reference

Clinical Neuroimaging, Volume 3, Issue 1, 2026.
ABSTRACT Background Three‐dimensional vessel wall imaging (VWI) using 3T MRI enables detailed assessment of intracranial atherosclerotic stenosis (ICAS), but the optimal reference tissue and its clinical utility remain unclear. This study aimed to identify the most suitable reference tissue for contrast‐enhanced (CE) VWI and to clarify imaging ...

Morphologic and Morphometric Study of the Heart and Its Great Arteries in the Common Pheasant (Phasianus colchicus)

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
The common pheasant heart is elongated and conical, with thicker left ventricular walls and a complex atrioventricular valve structure. Purkinje fibres show strong desmin but no α‐SMA expression, providing detailed insights into cardiovascular morphology and adaptations in birds, supporting comparative and conservation studies.

Metabolic Syndrome and Atrial Cardiomyopathy on the Risk of Stroke Mortality in the General Population

Annals of Noninvasive Electrocardiology, Volume 31, Issue 1, January 2026.
Metabolic syndrome and atrial cardiomyopathy each show a positive but statistically non‐significant association with stroke mortality, but their coexistence confers a synergistically higher risk. ABSTRACT Introduction Metabolic syndrome (MetS) and atrial cardiomyopathy (AtCM) are recognized as risk factors for cardiovascular disease, including stroke ...
