Hemodynamic Significance of APEXCT Coronary Angiography Combined With Dynamic CT Myocardial Perfusion Imaging in Assessing Restenosis After Coronary Stenting

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study aimed to evaluate the hemodynamic significance of in‐stent restenosis (ISR) by using a combined anatomical‐functional approach with photon‐counting CT coronary angiography (APEX‐CT CTA) and dynamic CT myocardial perfusion imaging (CT‐MPI). We prospectively enrolled 239 symptomatic patients at least 9 months after PCI.

Adjunctive Hyperbaric Oxygen Therapy or Intratympanic Steroids in Sudden Sensorineural Hearing Loss?

open access: yesThe Laryngoscope, EarlyView.
Sudden sensorineural hearing loss is traditionally treated with steroids, either orally and/or via intratympanic injections, and hyperbaric oxygen treatment (HBOT) has resurged in popularity as an adjunctive therapy. The study has not found any additional treatment benefit with adjunctive concurrent HBOT; however, HBOT might be of value to patients ...

Adipose‐derived small extracellular vesicles exacerbate microvascular dysfunction in heart failure with preserved ejection fraction via mmu‐miR‐582‐3p‐mediated Rap1b suppression

open access: yesInterdisciplinary Medicine
Heart failure with preserved ejection fraction (HFpEF) is characterized by diastolic dysfunction despite a preserved left ventricular ejection fraction, and visceral adipose tissue is implicated in its pathogenesis.

A Bibliometric‐Based Review of Biochar for Salt‐Affected Soil Restoration: Mapping Research Trends and Future Directions

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT In recent years, biochar has been studied for its range of applications. Recognized by the IPCC as a key Carbon Dioxide Removal (CDR) strategy, it also stands out as an important tool for reclaiming degraded lands, including vast global areas affected by salinity, such as those in China, India, and Australia.

Motion‐Compensated Diffusion Imaging With Phase‐Contrast for Robust Quantification of Regional Cerebral Blood Flow

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and evaluate a motion‐compensated diffusion imaging with phase‐contrast (MC‐DIP) technique for mitigating errors in regional cerebral blood flow (rCBF) quantification caused by physiological brain motion. Methods Diffusion‐weighted images were acquired in 11 healthy volunteers on a 3.0 T MRI system using three gradient ...

On‐Chip Evaluation of Red Blood Cell Deformability Through Transit Velocity Index in Hematological Diseases

open access: yesSmall, EarlyView.
The deformability of red blood cell is essential for smooth microcirculation. We propose a deformability index using a microfluidic platform with capillary‐like constrictions, based on the relationship between cell deformation and transit velocity through the constrictions. Its effectiveness and clinical potential have been demonstrated in applications

Brain Pericytes and Wnt/β‐Catenin Signaling Induce Functional Blood–Brain Barrier Phenotype in Human iPSC‐Derived Model

open access: yesSmall Methods, EarlyView.
This study shows that human iPSC‐derived endothelial cells acquire a functional blood–brain barrier phenotype when co‐cultured with brain pericytes and stimulated with CHIR‐99021, a Wnt/β‐catenin activator. This model recapitulates key barrier properties, inflammatory responses, and transcriptomic features of the native human BBB, offering new ...
