Fulvine and the pulmonary circulation [PDF]
Thorax, 1971 The pyrrolizidine alkaloid, fulvine, is now accepted as a major cause of veno-occlusive disease of the liver in the West Indies, where it is ingested as a decoction of the plant Crotalaria fulva in bush tea. Fulvine is similar in chemical structure to monocrotaline, which is known to cause pulmonary hypertension in rats.

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

Megakaryocytes in the Pulmonary Circulation [PDF]
Blood, 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.

Biology and function of pericytes in the vascular microcirculation
Animal 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 ...

Discovery of the pulmonary circulation [PDF]
European Heart Journal, 2016 A reply to a reply: From ancient Persia (before 637 AD) to William Harvey (17th Century AD) We read with the great interest the response of Bestett and Couto1 to our last publication on the discovery of pulmonary circulation by ancient Persians.2 The authors claimed that the credit for the discovery of the pulmonary circulation should be given to ...
