Recent applications of magnetic iron oxide nanoparticles for cerebral blood volume quantification in functional magnetic resonance imaging

Ibrain, EarlyView.
This study explores the recent advances in the use of iron oxide nanoparticles (IONPs) in functional MRI (fMRI) for studying brain functions, specifically cerebral blood volume (CBV) measurements. It covers fMRI techniques, magnetic nanoparticle synthesis, coating methods, and their applications in CBV imaging, in comparison to other contrast agents in

Vascular dysfunction in women with recurrent pregnancy loss: Possible association with antiphospholipid antibodies

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 206-214, April 2025.
Abstract Objective Antiphospholipid antibodies (aPL) are recognized to have a pivotal role in recurrent pregnancy loss (RPL) and cardiovascular disease. Therefore, we assessed the vascular function of women with RPL and examined the association with each type of aPL.

Red blood cell endothelial nitric oxide synthase: A major player in regulating cardiovascular health

British Journal of Pharmacology, EarlyView., 2023
Abstract Red blood cells (RBCs) have traditionally been seen as simple carriers of gases and nutrients in the body. One important non‐canonical function of RBCs in the cardiovascular system is the regulation of nitric oxide (NO) metabolism. It has been shown that RBCs can scavenge NO, transport NO metabolites and produce NO in hypoxic conditions ...

Modeling of Blood Flow Dynamics in Rat Somatosensory Cortex

Biomedicines
Background: The cerebral microvasculature forms a dense network of interconnected blood vessels where flow is modulated partly by astrocytes. Increased neuronal activity stimulates astrocytes to release vasoactive substances at the endfeet, altering the ...

Recurrent Priapism After Living Donor Kidney Transplantation Requiring Bilateral T‐Shunt Procedure: A Case Report

IJU Case Reports, EarlyView.
ABSTRACT Introduction Priapism is a persistent penile erection lasting > 4 h without sexual stimulation. Ischemic priapism requires urgent management. We report a recurrent ischemic priapism case post‐living‐donor kidney transplantation necessitating multiple interventions, including bilateral T‐shunt procedures.

Should the non‐canonical pathway of nitric oxide generation be targeted in hypertensive pregnancies?

British Journal of Pharmacology, EarlyView., 2023
Abstract Hypertension in pregnancy is prevalent, affecting around 10% of pregnancies worldwide, and significantly increases the risk of adverse outcomes for both mothers and their babies. Current treatment strategies for pregnant women with hypertension are limited, and new approaches for the management of hypertension in pregnancy are urgently needed.

Effects of 1267 nm Illumination on Microcirculation Regulatory Mechanisms

Journal of Biophotonics, EarlyView.
The question of activation of blood flow regulatory mechanisms during laser illumination remains open to date. This study showed the effect of laser exposure on the microcirculatory bed, which appears in the form of endothelium‐dependent vascular activity.
