Atención al recién nacido con hipertensión pulmonar persistente
(Sociedad de Cirugía de Bogotá, Hospital de San José y Fundación Universitaria de Ciencias de la Salud, 2016-12-01)
Plasmatic concentrations of ADMA and homocystein in llama (Lama glama) and regulation of arginase type II: an animal resistent to the development of pulmonary hypertension induced by hypoxia
(Frontiers Media SA., 2018-05-29)
There are animal species that have adapted to life at high altitude and hypobaric hypoxia conditions in the Andean highlands. One such species is the llama (Lama glama), which seem to have developed efficient protective ...
Melatonin long-lasting beneficial effects on pulmonary vascular reactivity and redox balance in chronic hypoxic ovine neonates
(Wiley, 2020)
Pulmonary arterial hypertension of the neonate (PAHN) is a pathophysiological condition
characterized by maladaptive pulmonary vascular remodeling and abnormal
contractile reactivity. This is a multifactorial syndrome ...
The heme oxygenase-carbon monoxide system in the regulation of cardiorespiratory function at high altitude
(2012)
Pulmonary arterial hypertension is one of the most serious pathologies that can affect the 140 million people living at altitudes over 2500. m. The primary emphasis of this review is pulmonary artery hypertension in mammals ...
Systemic oxidative stress and endothelial dysfunction is associated with an attenuated acute vascular response to inhaled prostanoid in pulmonary artery hypertension patients
(2011)
Background: Systemic endothelial dysfunction and increased oxidative stress have been observed in pulmonary arterial hypertension (PAH). We evaluate whether oxidative stress and endothelial dysfunction are associated with ...
Fetal and postnatal pulmonary circulation in the Alto Andino
(Elsevier, 2011)
Lowland mammals at high altitude constrict the pulmonary vessels, augmenting vascular resistance and
developing pulmonary arterial hypertension. In contrast, highland mammals, like the llama, do not
present pulmonary ...
Melatonin reduces oxidative stress and improves vascular function in pulmonary hypertensive newborn sheep
(Wiley, 2015)
Pulmonary hypertension of the newborn (PHN) constitutes a critical condition with severe cardiovascular and neurological consequences. One of its main causes is hypoxia during gestation, and thus, it is a public health ...
Purinergic receptor stimulation induces calcium oscillations and smooth muscle contraction in small pulmonary veins
(Wiley, 2018-07)
The small pulmonary veins (SPVs) may play a role in the development of pulmonary hypertension and pulmonary oedema via active changes in SPV diameter, mediated by vascular smooth muscle cell (VSMC) contraction. However, ...
The role of nitric oxide in the cardiopulmonary response to hypoxia in highland and lowland newborn llamas
(Blackwell Publishing Ltd, 2018)
© 2018 The Physiological Society. Key points: Perinatal hypoxia causes pulmonary hypertension in neonates, including humans. However, in species adapted to hypoxia, such as the llama, there is protection against pulmonary ...
The Action of 2-aminoethyldiphenyl borinate on the pulmonary arterial hypertension and remodeling of high-altitude hypoxemic lambs
(Frontiers Media, 2022)
Calcium signaling is key for the contraction, differentiation, and proliferation of pulmonary arterial smooth muscle cells. Furthermore, calcium influx through store-operated channels (SOCs) is particularly important in ...
