Application of [18F]FLT‐PET in pulmonary arterial hypertension: a clinical study in pulmonary arterial hypertension patients and unaffected bone morphogenetic protein receptor type 2 mutation carriers [PDF]

open access: yes, 2021
Pulmonary arterial hypertension is a heterogeneous group of diseases characterized by vascular cell proliferation leading to pulmonary vascular remodelling and ultimately right heart failure. Previous data indicated that 3′‐deoxy‐3′‐[18F]‐fluorothymidine

Megakaryocytes in the Pulmonary Circulation [PDF]

open access: yesBlood, 1963
Abstract The streptolysin 0 hemolysis method for isolation of cancer cells in the blood was employed for direct observations of the incidence and some characteristics of circulating megakaryocytes. In a series of 168 patients, circulating megakaryocytes were found in 77 per cent of the blood samples.

Echocardiographic Prognosis Relevance of Attenuated Right Heart Remodeling in Idiopathic Pulmonary Arterial Hypertension

open access: yesFrontiers in Cardiovascular Medicine, 2021
Background: Right ventricular (RV) function is a great determination of the fate in patients with pulmonary arterial hypertension (PAH). Monitoring RV structure back to normal or improvement should be useful for evaluation of RV function.

Chemical and biological assessment of metal organic frameworks (MOFs) in pulmonary cells and in an acute in vivo model: relevance to pulmonary arterial hypertension therapy [PDF]

open access: yes, 2017
Pulmonary arterial hypertension (PAH) is a progressive and debilitating condition. Despite promoting vasodilation, current drugs have a therapeutic window within which they are limited by systemic side effects.

Pilot study of losartan for pulmonary hypertension in chronic obstructive pulmonary disease. [PDF]

open access: yes, 2005
BACKGROUND: Morbidity in COPD results from a combination of factors including hypoxia-induced pulmonary hypertension, in part due to pulmonary vascular remodelling. Animal studies suggest a role of angiotensin II and acute studies in man concur.

Circular RNAs in pulmonary hypertension: Emerging biological concepts and potential mechanism

open access: yesAnimal Models and Experimental Medicine, 2022
Circular RNAs (circRNAs) are endogenous RNAs with a covalently closed single‐stranded transcript. They are a novel class of genomic regulators that are linked to many important development and disease processes and are being pursued as clinical and ...

CircGSAP regulates the cell cycle of pulmonary microvascular endothelial cells via the miR-942-5p sponge in pulmonary hypertension

open access: yesFrontiers in Cell and Developmental Biology, 2022
Background We recently demonstrated that circGSAP was diminished in lung tissues from patients with pulmonary arterial hypertension and in hypoxia-induced pulmonary microvascular endothelial cells (PMECs).

Differences in disease severity and prognosis of exercise-induced right-to-left shunt between idiopathic pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension patients

open access: yesFrontiers in Cardiovascular Medicine, 2022
ObjectiveWhether exercise-induced venous-to-systemic shunt (EIS) during cardiopulmonary exercise testing (CPET) has different manifestations or characteristics in idiopathic pulmonary arterial hypertension (IPAH) and chronic thromboembolic pulmonary ...

Biology and function of pericytes in the vascular microcirculation

open access: yesAnimal Models and Experimental Medicine, 2023
Pericytes are the main cellular components of tiny arteries and capillaries. Studies have found that pericytes can undergo morphological contraction or relaxation under stimulation by cytokines, thus affecting the contraction and relaxation of ...
