Clinical and haemodynamic evaluation of chronic thromboembolic pulmonary hypertension patients scheduled for pulmonary thromboendarterectomy: Is schistosomiasis hypertension an important confounding factor?
(Faculdade de Medicina / USP, 2010)
INTRODUCTION: Chronic thromboembolic pulmonary hypertension is a disease affecting approximately 4,000 people per year in the United States. The incidence rate in Brazil, however, is unknown. The estimated survival for ...
Pulmonary fibrosis secondary to COVID-19: a narrative review
(2021-01-01)
Introduction: Coronavirus disease 2019 (COVID-19) is still increasing worldwide, and as a result, the number of patients with pulmonary fibrosis secondary to COVID-19 will expand over time. Risk factors, histopathological ...
Revisiting the role of TRP, orai, and ASIC channels in the pulmonary arterial response to hypoxia
(Frontiers Media S.A., 2018)
© 2018 Reyes, Castillo-Galán, Hernandez, Herrera, Ebensperger and Llanos. The pulmonary arteries are exquisitely responsive to oxygen changes. They rapidly and proportionally contract as arterial PO2 decrease, and they ...
Melatonin decreases pulmonary vascular remodeling and oxygen sensitivity in pulmonary hypertensive newborn lambs
(Frontiers media SA, 2018)
Background: Chronic hypoxia and oxidative stress during gestation lead to pulmonary hypertension of the neonate (PHN), a condition characterized by abnormal pulmonary arterial reactivity and remodeling. Melatonin has strong ...
Hypoxic pulmonary vasoconstriction in reptiles: a comparative study of four species with different lung structures and pulmonary blood pressures
(Amer Physiological Soc, 2005-11-01)
Low O-2 levels in the lungs of birds and mammals cause constriction of the pulmonary vasculature that elevates resistance to pulmonary blood flow and increases pulmonary blood pressure. This hypoxic pulmonary vasoconstriction ...

2-Aminoethyldiphenylborinate modifies the pulmonary circulation in pulmonary hypertensive newborn lambs partially gestated at high altitude
(Amer Physiological Soc., 2016)
Calcium signaling through store-operated channels (SOC) is involved in hypoxic pulmonary hypertension. We determined whether a treatment with 2-aminoethyldiphenylborinate (2-APB), a compound with SOC blocker activity, ...
Treating Inflammation Associated with Pulmonary Hypertension: An Overview of the Literature
(2022-01-01)
Pulmonary hypertension (PH) comprises five groups of serious clinical entities characterized by pulmonary artery vasoconstriction and vascular remodeling leading to right heart failure and death. In addition to vascular ...
Effects of arm bracing posture on respiratory muscle strength and pulmonary function in patients with chronic obstructive pulmonary diseaseEfeitos do apoio dos membros superiores sobre a força muscular respiratória e função pulmonar de pacientes com doença pulmonar obstrutiva crônica
(2010-01-01)
Objective: To analyze the effect of arm bracing posture on respiratory muscle strength and pulmonary function in patients with Chronic Obstructive Pulmonary Disease (COPD). Methods: 20 patients with COPD (11 male; 67 ± 8 ...
The role of nitric oxide signaling in pulmonary circulation of high- and low-altitude newborn sheep under basal and acute hypoxic conditions
(Academic Press Inc., 2019)
Nitric oxide (NO) is the main vasodilator agent that drives the rapid decrease of pulmonary vascular resistance for the respiratory onset during the fetal to neonatal transition. Nevertheless, the enhanced NO generation ...
