Glucocorticoids modulate drug transporter function in human fetal brain endothelial cells

The Journal of Physiology, EarlyView.
Abstract figure legend P‐glycoprotein and breast cancer resistance protein are the most prominent drug transporters at the fetal blood–brain barrier. We isolated primary human fetal brain endothelial cells from early and mid‐gestation cerebral microvessels and exposed them to glucocorticoids cortisol and dexamethasone in vitro.

Inter‐Shot Motion Correction of Segmented 3D‐GRASE ASL Perfusion Imaging With Self‐Navigation and CAIPI

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1557-1571, October 2026.
ABSTRACT Purpose Segmented 3D Gradient and Spin Echo (GRASE) is commonly used in Arterial Spin Labeling (ASL) perfusion imaging. However, it is vulnerable to inter‐shot motion, leading to subtraction errors that cannot be corrected. We developed a retrospective self‐navigated inter‐shot motion correction method for segmented 3D‐GRASE ASL imaging with ...

Zero‐Shot Self‐Supervised Learning of Single Breath‐Hold Magnetic Resonance Cholangiopancreatography (MRCP) Reconstruction

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1666-1681, October 2026.
ABSTRACT Purpose To investigate the feasibility of zero‐shot self‐supervised learning reconstruction for reducing breath‐hold times in magnetic resonance cholangiopancreatography (MRCP). Methods Breath‐hold MRCP was acquired from 11 healthy volunteers on 3T scanners using an incoherent k‐space sampling pattern, leading to a 14‐s acquisition time and an

Design of an 8‐Channel Transmit 32‐Channel Receive 11.7T Head Coil and Evaluation of SNR Gains

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 2004-2018, October 2026.
ABSTRACT Purpose To design and develop an 8‐channel transmit 32‐channel receive 11.7T head coil for the strongest human MRI scanner to date, demonstrate safety, and evaluate signal‐to‐noise ratio (SNR) gains compared to 7T, the most used ultra‐high‐field (UHF) platform.

Prospective Head Motion Correction in T1‐ and T2‐Weighted Long Echo Train Sequences Using Servo Navigation

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1741-1754, October 2026.
ABSTRACT Purpose To integrate MR‐based servo navigation in MPRAGE and 3D‐TSE sequences and demonstrate its potential for prospective head motion correction in structural imaging. Methods Repeated modules of servo navigators were inserted before each preparation pulse of MPRAGE and 3D‐TSE sequences (before‐prep) for rapid convergence of motion parameter

Upper‐Limb Paresis Severity Is Associated With Practice Dosage During Task‐Oriented Training in Subacute Stroke—An Exploratory Secondary Analysis

Physiotherapy Research International, Volume 31, Issue 4, October 2026.
ABSTRACT Background and Purpose Intensive, high‐repetition practice is one of the strategies incorporated into upper‐limb task‐oriented training (UL‐TOT) to promote experience‐dependent neural plasticity after stroke. Although a target of 300 repetitions during a one‐hour UL‐TOT session is feasible, considerable variability in the practice dosage ...

Optimal Selection of the Effective Echo Time (TEeff ) for T2‐Weighted Fast‐Spin‐Echo MRI of the Prostate at 3.0 T: Effect on Lesion Conspicuity

Journal of Magnetic Resonance Imaging, Volume 64, Issue 3, Page 616-628, September 2026.
ABSTRACT Background Clinical T 2‐weighted (T2W) MRI of prostate cancer (PCa) usually implements a 2D fast‐spin‐echo (FSE) sequence, but understanding the echo‐time‐dependent contrast behavior is not straightforward due to the complicated FSE signal evolution.

Maximum Likelihood Turbo Iterative Channel Estimation for Space-Time Coded Systems and Its Application to Radio Transmission in Subway Tunnels

EURASIP Journal on Advances in Signal Processing, 2004
This paper presents a novel channel estimation technique for space-time coded (STC) systems. It is based on applying the maximum likelihood (ML) principle not only over a known pilot sequence but also over the unknown symbols in a data frame.

Cerebral Blood Transit in Sickle Cell Anemia

Journal of Magnetic Resonance Imaging, Volume 64, Issue 3, Page 738-750, September 2026.
ABSTRACT Background Sickle cell anemia (SCA) patients upregulate cerebral blood flow to compensate for decreased arterial oxygen content. Such hyperemic conditions can manifest as venous hyperintense signal on arterial spin labeling (ASL) MRI, which may reflect faster capillary blood transit, altered oxygen extraction fraction (OEF), and infarct risk ...
