Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Ischemic Stroke in Hypereosinophilic Syndrome: A Clinicopathologic Study of Two Cases

Neuropathology, Volume 46, Issue 1, February 2026.
ABSTRACT Ischemic stroke is a rare complication of hypereosinophilic syndrome (HES). Manifestations of stroke in HES have been described in the radiologic literature; however the pathologic characterization of central nervous system (CNS) involvement in HES is limited.

Absolute quantification of cerebral metabolites using two‐dimensional proton MR spectroscopic imaging with quantitative MRI‐based water reference

Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 4-19, January 2026.
Abstract Purpose Metabolite concentrations are valuable biomarkers in brain tumors (BTs). However, absolute quantification of metabolites using MR spectroscopy requires a correction of water relaxation using time‐consuming quantitative MRI (qMRI) sequences in addition to a lengthy two‐dimensional spectroscopic water‐reference acquisition.

Longitudinal MRI Characterization of T1 and T2 Relaxation Times in an Amyloid Mouse Model of Alzheimer's Disease at 11.7 T

NMR in Biomedicine, Volume 39, Issue 1, January 2026.
In this study, we systematically characterized the longitudinal evolution of T1 and T2 relaxation times at the early to middle stage of Tg2576 mouse model representing the amyloidosis subtype of Alzheimer’s disease. We found that rates of change in relaxation times within the thalamus, hypothalamus, and piriform cortex may serve as markers for ...

A CSF Background Suppression Scheme in Arterial Spin Labeling MRI

NMR in Biomedicine, Volume 39, Issue 1, January 2026.
Arterial spin labeling MRI suffers from signal instability due to CSF pulsation, which are not fully addressed by conventional tissue‐focused background suppression (BS). We developed a CSF BS scheme and demonstrated its advantages in both single‐ and multi‐delay ASL.

Syndrome of Inappropriate Secretion of Antidiuretic Hormone in a Dog With Meningoencephalitis of Unknown Etiology

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
This report describes a case of syndrome of inappropriate antidiuretic hormone secretion (SIADH) in a Maltese with meningoencephalitis of unknown etiology (MUE). The dog was treated with water restriction and tolvaptan, a vasopressin receptor antagonist, which resulted in an improvement in hyponatremia.

cIMPACT‐NOW update 11: Proposal on adaptation of diagnostic criteria for IDH‐ and H3‐wildtype diffuse high‐grade gliomas and for posterior fossa ependymal tumors

Brain Pathology, Volume 36, Issue 1, January 2026.
Abstract The Consortium to Inform Molecular and Practical Approaches to Central Nervous System Tumor Taxonomy (cIMPACT‐NOW) updates provide guidelines for the diagnosis of central nervous system (CNS) tumors and suggestions for future World Health Organization (WHO) classification.

Novel Magnetic Resonance Imaging Findings of Bilaterally Symmetrical Lesions in a Dog With Concomitant Granulomatous Meningoencephalitis and Necrotizing Encephalitis

Veterinary Radiology &Ultrasound, Volume 67, Issue 1, January 2026.
ABSTRACT A 3‐year‐old, female neutered Bichon Frise was presented with a 2‐day history of behavioral changes and ataxia. The neurological examination was consistent with diffuse forebrain involvement, with left lateralization. An MRI study identified bilaterally symmetrical T2W/T2 fluid‐attenuated inversion recovery (T2‐FLAIR) hyperintense, T1W ...

HyperSight CBCT image quality and metal artifact reduction for adaptive head and neck radiotherapy: Results from a prospective clinical trial

Journal of Applied Clinical Medical Physics, Volume 26, Issue 12, December 2025.
Abstract Background Accurate Hounsfield units (HU) are critical for dose calculation and anatomical visualization, but are often affected by dental artifacts in head and neck (H&N) cancer patients. The HyperSight cone‐beam computed tomography (CBCT) platform provides improved image quality over previous CBCT platforms and offers metal artifact ...
