APOE4 and cognition in intracranial atherosclerosis: beyond Alzheimer's pathology

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION The apolipoprotein E ε4 (APOE ε4) allele is a major genetic risk factor for Alzheimer's disease, but its relevance to cognition in intracranial atherosclerosis (ICAS) remains unclear. We investigated the association between APOE ε4 and cognition in ICAS. METHODS Baseline data from a multicenter cohort were analyzed.

Presenilin L166P Mutation, a Model of Familial Alzheimer's Disease, Leads to Early Onset Bone Loss

Comprehensive Physiology, Volume 16, Issue 1, February 2026.
Female‐specific bone loss in Alzheimer's disease mouse models: There is a significant alteration of bone phenotype during Alzheimer's disease. Using integrated imaging and biological assays, we observed changes in the bone microarchitecture, composition, and function in PSEN K1 and PSEN1/hAPP Tg+ mice, predominantly in the females. ABSTRACT Accelerated

Bidirectional crusher gradient method to estimate the labeling efficiency of pseudo‐continuous arterial spin labeling MRI in mice

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 912-926, February 2026.
Abstract Purpose To develop an experimental method for measuring the labeling efficiency of pseudo‐continuous arterial spin labeling (pCASL) MRI in mice. Methods We propose a method using bidirectional crusher gradients to modulate vascular signals in the azygos pericallosal artery (azPA) of the mouse brain, applied with and without pCASL labeling.

ISME—incoherent sampling of multi‐echo data to minimize cardiac‐induced noise in brain maps of R2*$$ {R}_2^{\ast } $$ and magnetic susceptibility

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 897-911, February 2026.
Abstract Purpose Maps of the MRI parameters R2*$$ {\mathrm{R}}_2^{\ast } $$ and magnetic susceptibility (χ$$ \chi $$) enable the investigation of microscopic tissue changes in brain disease. However, cardiac‐induced signal instabilities increase the variability of brain maps of R2*$$ {\mathrm{R}}_2^{\ast } $$ and χ$$ \chi $$.

Internationally Educated Nurses' Experiences of Working in U.S. Long‐Term Care Settings

Research in Nursing &Health, Volume 49, Issue 1, Page 74-86, February 2026.
ABSTRACT Increasing reliance on Internationally Educated Nurses (IENs) in the U.S. healthcare system, particularly in Long‐Term Care (LTC) settings, necessitates an in‐depth exploration of their transition experiences. The primary purpose of this qualitative study was to understand how IENs describe their experiences transitioning to work with older ...
