Microvascular Health as a Key Determinant of Organismal Aging

open access: yesAdvanced Science, EarlyView.
This review spotlights the emerging field of vascular aging, providing a comprehensive and critical overview of the molecular processes and clinical manifestations of vascular dysfunction during aging. By combining basic angioscience concepts with a critical analysis of innovative pre‐clinical aging models and lifestyle interventions, it offers a ...

The efficacy of nitric oxide in stroke (ENOS) trial – where do we stand in Romania? [PDF]

open access: yesRomanian Journal of Neurology, 2012
Introduction. Romania ranks third worldwide for stroke mortality. Although high blood pressure (BP) is a major risk factor for stroke incidence and determinant of outcome, the management of BP in acute stroke remains undefined. The present study assesses

Differential sensitivity of basal and acetylcholine-induced activity of nitric oxide to blockade by asymmetric dimethylarginine (ADMA) in the rat aorta [PDF]

open access: yes, 2010
<b>Background and purpose</b>: Previous work has shown that NG-monomethyl-l-arginine (l-NMMA) paradoxically inhibits basal, but not ACh-stimulated activity of nitric oxide in rat aorta.

Novel Vascularized Human Liver Organoids for Modeling Alcohol‐Induced Liver Injury and Developing Hepatoprotective Therapy

open access: yesAdvanced Science, EarlyView.
This study successfully engineered vascularized liver organoids (3HLOs) by co‐culturing human reprogrammed hepatocyte‐like cells (hrHLs) with human umbilical vein endothelial cells (HUVECs) and human umbilical mesenchymal stem cells (HUMSCs). Upon implantation, the 3HLOs established functional vascular anastomosis with the host circulation and ...

Engineered Multifunctional Hydrogel Delivering Novel CBX7 Inhibitor Modulates Cuproptosis Via Liquid–Liquid Phase Separation to Restore Cardiac Function in Aged Myocardial Infarction

open access: yesAdvanced Science, EarlyView.
An age‐adapted therapy pairs δ‐Amyrenone, a CBX7 inhibitor, with an alginate hydrogel (CSAδ) to rescue infarcted elderly hearts. CSAδ disrupts CBX7–ATP7A liquid–liquid phase separation, restores ATP7A trafficking and copper efflux, suppresses cuproptosis, supplies oxygen, scavenges ROS, promotes M2 polarization, supports angiogenesis, and enhances ...

Mechanisms of endothelial cell dysfunction in cystic fibrosis [PDF]

open access: yes, 2017
Although cystic fibrosis (CF) patients exhibit signs of endothelial perturbation, the functions of the cystic fibrosis conductance regulator (CFTR) in vascular endothelial cells (EC) are poorly defined.

Carbon Monoxide Nanomodulator Reverses Ischemia‐Reperfusion Injury in Stroke: A Novel Dual‐Channel Therapy Mode of Co‐driving Neuroprotection and Neurogenesis

open access: yesAdvanced Science, EarlyView.
This work develops a biomimetic and reactive oxygen species‐activated carbon monoxide (CO) nanogenerator to penetrate blood‐brain barrier, arrive in stroke‐affected regions, and release CO in a controlled manner for an innovative dual‐channel therapy strategy via co‐driving neuroprotection and neurogenesis.

Environmental Pollutant Hexachlorobenzene Induces Hypertension In a Rat Model [PDF]

open access: yes, 2018
Hexachlorobenzene (HCB) is a dioxin-like environmental pollutant, widely distributed in the environment. New research links exposure to high levels of persistent organic environmental toxicants to cardiovascular disease, however little is known about the

Affinity‐Based Protein Profiling Revealed that HIGD1A is a Direct Target Protein of Aristolochic Acids

open access: yesAdvanced Science, EarlyView.
Using an affinity‐based probe, this study reveals that aristolochic acid directly binds to HIGD1A with high affinity in the kidney. This binding disrupts the HIGD1A‐TFAM interaction, which in turn triggers TFAM degradation, cytosolic mitochondrial DNA release, and the activation of inflammatory pathways. Abstract Exposure to aristolochic acids (AA) via
