Mechanisms maintaining right ventricular contractility-to-pulmonary arterial elastance ratio in VA ECMO: a retrospective animal data analysis of RV–PA coupling

Journal of Intensive Care
Background To optimize right ventricular–pulmonary coupling during veno-arterial (VA) ECMO weaning, inotropes, vasopressors and/or vasodilators are used to change right ventricular (RV) function (contractility) and pulmonary artery (PA) elastance ...

The Impact of Obesity on Durable Left Ventricular Assist Device Implantation: A Systematic Review and Meta‐Analysis

Artificial Organs, EarlyView.
14 100 LVAD patients across 21 studies were analyzed. Findings indicated that obese LVAD recipients had lower short‐term mortality and higher risk of infection, thrombosis and right heart failure. There was no difference in long‐term survival between obese and non‐obese patients.

Non‐canonical PKG1 regulation in cardiovascular health and disease

British Journal of Pharmacology, EarlyView.
It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.

Hipoksia Pada Sirkulasi Pulmonal

JKS (Jurnal Kedokteran Syiah Kuala), 2007
Abstrak, Hipoxic pulmonary vasoconstriction terutama terjadi pada arteri pulmonalis kecil, dimana hipoksia alveoli merupakan faktor penyebab utama. Akibat nyata dari hipoksia alveoli adalah proses muskularisasi pada arteri pulmonalis berdiameter kurang ...

Severe asthma is associated with a remodeling of the pulmonary arteries in horses.

PLoS ONE, 2020
Pulmonary hypertension and cor pulmonale are complications of severe equine asthma, as a consequence of pulmonary hypoxic vasoconstriction. However, as pulmonary hypertension is only partially reversible by oxygen administration, other etiological ...

Cytochrome P450 1A1 influences obesity‐induced pulmonary hypertension

British Journal of Pharmacology, EarlyView.
Background and Purpose The contribution of obesity to pulmonary arterial hypertension (PAH) pathophysiology remains poorly understood. Adipose tissue synthesises estrogens via cytochrome P450 (CYP) 19A1 (aromatase), whereas circulating estrogens are metabolised in the lung by CYP1A1.

Sustained Hypoxic Pulmonary Vasoconstriction in the Isolated Perfused Rat Lung: Effect of α1-adrenergic Receptor Agonist

Iranian Journal of Medical Sciences, 2014
Background: Alveolar hypoxia induces monophasic pulmonary vasoconstriction in vivo, biphasic vasoconstriction in the isolated pulmonary artery, and controversial responses in the isolated perfused lung.

Role of RIPK1/RIPK3/MLKL signalling pathway in sepsis‐associated acute kidney injury

Experimental Physiology, EarlyView.
Abstract Sepsis‐associated acute kidney injury (SA‐AKI) is a common clinical syndrome in critically ill patients, and its high mortality rate is closely related to complex pathological mechanisms. Existing studies have shown that the pathophysiological process of SA‐AKI involves complex multi‐mechanism interactions, including an uncontrolled systemic ...

Modulation of cerebral blood flow and cognition by hyperthermia and hypoxia: An electroencephalographic event‐related potentials perspective

Experimental Physiology, EarlyView.
Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...

Human adaptation to high‐altitude: A contemporary comparison of the oxygen cascade in Andean, Tibetan and Ethiopian highlanders

Experimental Physiology, EarlyView.
Abstract Human populations native to high altitude have evolved distinct physiological adaptations to chronic hypoxia. This adaptation is evident in the O2 transport cascade. In this review, with brief inclusion of the related genetic adaptations, we compare the O2 cascade across three well‐characterized high‐altitude populations: Andeans (Aymara and ...
