Effect of exercise training in rats exposed to chronic hypoxia: Application for Monge's disease. [PDF]

Physiol Rep, 2021
Exercise training limited chronic hypoxia‐induced decline in physical capacity. Exercise training decreased hematocrit through mechanical hemolysis. Exercise training in hypoxia have a beneficial effect on excessive erythropoiesis Abstract Physical exercise may improve hematological conditions in high altitude dwellers suffering from Chronic Mountain ...

Sub-maximal aerobic exercise training reduces haematocrit and ameliorates symptoms in Andean highlanders with chronic mountain sickness. [PDF]

Exp Physiol, 2021
New Findings What is the central question of this study? What is the effect of sub‐maximal aerobic exercise training on signs and symptoms of chronic mountain sickness (CMS) in Andean highlanders? What is the main finding and its importance? Aerobic exercise training (ET) effectively reduces haematocrit, ameliorates symptoms and improves aerobic ...

Effect of chronic high-altitude hypoxia on retinal vascular phenotype, choroidal and retinal vasoreactivity in Peruvian highlanders. [PDF]

Exp Physiol
Abstract High‐altitude chronic hypoxia can induce excessive erythrocytosis (EE, defined as a haemoglobin concentration of ≥21 g/dL in men), leading to hyperviscosity and promoting endothelial dysfunction. We aimed to assess whether EE affects the retinal vascular phenotype and the ophthalmological vascular response to CO2.

Is resting muscle sympathetic nerve activity related to peripheral or cerebrovascular haemodynamics at high altitude? A retrospective analysis. [PDF]

Exp Physiol
Abstract High‐altitude hypoxia elicits several profound physiological responses, including substantial increases in muscle sympathetic nerve activity (MSNA); however, the association of this heightened MSNA with cardiovascular and cerebrovascular haemodynamics remains unclear in lowlanders and indigenous highlander populations.

Are coagulation profiles in Andean highlanders with excessive erythrocytosis favouring hypercoagulability? [PDF]

Exp Physiol
Abstract Chronic mountain sickness is a maladaptive syndrome that affects individuals living permanently at high altitude and is characterized primarily by excessive erythrocytosis (EE). Recent results concerning the impact of EE in Andean highlanders on clotting and the possible promotion of hypercoagulability, which can lead to thrombosis, were ...

A change of heart: Mechanisms of cardiac adaptation to acute and chronic hypoxia

The Journal of Physiology, Volume 600, Issue 18, Page 4089-4104, 15 September 2022., 2022
Abstract figure legend Responses of key cardio‐autonomic parameters to acute, prolonged, and lifelong hypoxia. Relative changes are plotted for lowlanders across the timelines of 0–12 h (left) and 1 day to 6 months (middle) and compared with observations in select populations residing at high altitude in Asia and South America (right).

Global REACH 2018: Andean highlanders, chronic mountain sickness and the integrative regulation of resting blood pressure

Experimental Physiology, Volume 106, Issue 1, Page 104-116, 1 January 2021., 2021
New Findings What is the central question of this study? Does chronic mountain sickness (CMS) alter sympathetic neural control and arterial baroreflex regulation of blood pressure in Andean (Quechua) highlanders? What is the main finding and its importance? Compared to healthy Andean highlanders, basal sympathetic vasomotor outflow is lower, baroreflex

Carotenoides bixina e norbixina extraídos do urucum (Bixa orellana L.) como antioxidantes em produtos cárneos Carotenoids bixin and norbixin from annatto (Bixa orellana L.) as antioxidants in meat products

Ciência Rural, 2012
A oxidação lipídica é uma das principais alterações que acometem os derivados cárneos em razão da composição química rica em lipídios e íons ferro, utilização de processos térmicos e de moagem, além do frequente uso do cloreto de sódio, um reconhecido ...
