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

, 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.

Rare association between giant-cell aortitis and giant-cell aortic valvulitis

Autopsy and Case Reports, 2023
Giant cell arteritis (GCA) is a type of chronic vasculitis that affects medium and large-caliber arteries, frequently related to aortic involvement and, consequently, to aneurysm formation. However, associated valvulitis with giant cells is uncommon. We

CONTRAST ENHANCED MRI IN THE ASSESSMENT OF THE RELATIONSHIPS OF ATHEROSCLEROTIC LESIONS OF CAROTID ARTERIES AND AORTIC WALL

Атеросклероз, 2017
Aim of the study. The relationships and connections of atherosclerotic damage of carotid arterial wall concomitant with atherosclerosis of thoracic aorta have been studied here, as from data of contrast-enhanced magnetic resonance imaging (MRI), and also

Aortic Origins of the Celiac Trunk and Superior Mesenteric Artery

Diagnostics, 2021
(1) Background. The vertebral level of origin (VLO) of the celiac trunk (CT) and superior mesenteric artery (SMA) has been scarcely investigated. (2) Method. This study used 107 computed tomography angiograms and an eleven type grading system to classify

Computational Simulations for Aortic Coarctation: Representative Results From a Sampling of Patients [PDF]

, 2011
Treatments for coarctation of the aorta (CoA) can alleviate blood pressure (BP) gradients(D), but long-term morbidity still exists that can be explained by altered indices of hemodynamics and biomechanics.

Chronic L-Name-Treatment Produces Hypertension by Different Mechanisms in Peripheral Tissues and Brain: Role of Central eNOS

Pathophysiology, 2020
The goal of our study was to analyze the time course of the effect of NG-nitro-L-arginine methyl ester (L-NAME) on nitric oxide synthase (NOS) isoforms and nuclear factor–κB (NF-κB) protein expression, total NOS activity, and blood pressure (BP) in rats.

Safety and Efficacy of Anticoagulation Therapy in Paediatric Patients With Solid Tumours or Lymphomas at Risk of Thrombocytopenia: A Retrospective Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Patients with solid tumours or lymphomas have an increased risk of thromboembolism (TE) and thrombocytopenia. Evidence‐based strategies for anticoagulation therapy (ACT) for patients with thrombocytopenia are limited. We examined the impact of thrombocytopenia on ACT administration and bleeding incidence in children with solid ...

Wave propagation and reflection in the aorta and implications of the aortic Windkessel

Exploration of Medicine, 2021
Some have said that it is inappropriate and perhaps impossible to consider wave and Windkessel phenomena simultaneously. For 50 years, arterial hemodynamics has been dominated by the frequency-domain “impedance analysis” in which it was assumed that all ...

Prolonged Corrected QT Interval as an Early Electrocardiographic Marker of Cyclophosphamide‐Induced Cardiotoxicity in Pediatric Hematology and Oncology Patients

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cyclophosphamide (CY) is associated with potentially fatal cardiotoxicity, yet no electrocardiographic indices have been established for early detection of CY‐induced cardiomyopathy. This study aimed to determine whether corrected QT interval (QTc) prolongation can predict early onset of CY‐related cardiac dysfunction in pediatric ...
