Attenuation of Piwil2 induced by hypoxic postconditioning prevents cerebral ischemic injury by inhibiting CREB2 promoter methylation

open access: yesBrain Pathology, Volume 33, Issue 1, January 2023., 2023
Schematic depicting mechanism by which HPC protects neurons against tGCI in CA1 through Piwil2‐mediated epigenetics. Abstract Epigenetic modification contributes to the pathogenesis of cerebral ischemia. Piwil2 belongs to the PIWI proteins subfamily and has a key role in the regulation of gene transcription through epigenetics.

Congenital absence of the internal carotid artery with intercavernous anastomosis

open access: yesRadiology Case Reports, 2019
Congenitally absent internal carotid artery with intercavernous anastomosis is an exceedingly rare vascular anomaly. We report such a case in a 65-year-old man with chronic symptoms resembling sporadic transient ischemic attacks. While these patients are

Physics-informed graph neural networks for flow field estimation in carotid arteries [PDF]

open access: yesarXiv
Hemodynamic quantities are valuable biomedical risk factors for cardiovascular pathology such as atherosclerosis. Non-invasive, in-vivo measurement of these quantities can only be performed using a select number of modalities that are not widely available, such as 4D flow magnetic resonance imaging (MRI).

Associations of Central Arterial Stiffness With Brain White Matter Integrity and Gray Matter Volume in MRI Across the Adult Lifespan

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
Background Central arterial stiffening is associated with brain white matter (WM) damage and gray matter (GM) volume loss in older adults, but little is known about this association from an adult lifespan perspective. Purpose To investigate the associations of central arterial stiffness with WM microstructural organization, WM lesion load, cortical ...

Supersulfide biology and translational medicine for disease control

open access: yesBritish Journal of Pharmacology, EarlyView., 2023
Abstract For decades, the major focus of redox biology has been oxygen, the most abundant element on Earth. Molecular oxygen functions as the final electron acceptor in the mitochondrial respiratory chain, contributing to energy production in aerobic organisms. In addition, oxygen‐derived reactive oxygen species including hydrogen peroxide and nitrogen

The Development and Challenges of PET/MRI Dual‐Modality Imaging Probes—An Update

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT The integration of Positron emission tomography (PET) with Magnetic resonance imaging (MRI) combines the functional imaging capabilities of PET with the high‐resolution anatomical detail of MRI, creating a synergistic platform for advanced diagnostic imaging and image‐guided therapies. Central to the success of this dual‐modality system is the
