Research progress of endoplasmic reticulum stress of hypoxic pulmonary hypertension [PDF]

Jichu yixue yu linchuang, 2023
Hypoxic pulmonary hypertension (HPH) is a serious complication caused by long-term hypoxia,which is characterized by persistent vasoconstriction and irreversible vascular remodeling.

Retracted: Chest digital dynamic radiography to detect changes in human pulmonary perfusion in response to alveolar hypoxia

Journal of Medical Radiation Sciences, 2023
Introduction Hypoxic pulmonary vasoconstriction optimises oxygenation in the lung by matching the local‐blood perfusion to local‐ventilation ratio upon exposure to alveolar hypoxia.

Acetazolamide prevents hypoxia‐induced reactive oxygen species generation and calcium release in pulmonary arterial smooth muscle

Pulmonary Circulation, 2021
Upon sensing a reduction in local oxygen partial pressure, pulmonary vessels constrict, a phenomenon known as hypoxic pulmonary vasoconstriction. Excessive hypoxic pulmonary vasoconstriction can occur with ascent to high altitude and is a contributing ...

Correlation of Pulse Wave Transit Time with Pulmonary Artery Pressure in a Porcine Model of Pulmonary Hypertension

Biomedicines, 2021
For the non-invasive assessment of pulmonary artery pressure (PAP), surrogates like pulse wave transit time (PWTT) have been proposed. The aim of this study was to invasively validate for which kind of PAP (systolic, mean, or diastolic) PWTT is the best ...

Dual role of the L-arginine–ADMA–NO pathway in systemic hypoxic vasodilation and pulmonary hypoxic vasoconstriction

Pulmonary Circulation, 2020
In healthy vascular endothelium, nitric oxide acts as a vasodilator paracrine mediator on adjacent smooth muscle cells. By activating soluble guanylyl cyclase, nitric oxide stimulates cyclic guanosine monophosphate (cGMP) which causes relaxation of ...

Regulation of rat intrapulmonary arterial tone by arachidonic acid and prostaglandin E2 during hypoxia. [PDF]

PLoS ONE, 2013
Arachidonic acid (AA) and its metabolites, prostaglandins (PG) are known to be involved in regulation of vascular homeostasis including vascular tone and vessel wall tension, but their potential role in Hypoxic pulmonary vasoconstriction (HPV) remains ...
