Hematocrit and hemoglobin levels at adulthood are determined by neonatal hypoxic exposure in rats living at high altitude
(High Altitude Medicine & Biology, 2010-08-08)
Introduction: In previous work performed at sea level we
reported that exposure to neonatal hypoxia impairs ventilatory and hematological responses to chronic hypoxia later in
life. These findings supported the hypothesis ...

Relationships Between Chemoreflex Responses, Sleep Quality, and Hematocrit in Andean Men and Women
(Frontiers Media, 2020)
Andean highlanders are challenged by chronic hypoxia and many exhibit elevated hematocrit (Hct) and blunted ventilation compared to other high-altitude populations. While many Andeans develop Chronic Mountain Sickness (CMS) ...
Hypoxia during embryonic development increases energy metabolism in normoxic juvenile chicks
(Elsevier B.V., 2017-05-01)
Environmental changes during perinatal development can affect the postnatal life. In this sense, chicken embryos that experience low levels of O-2 over a specific phase of incubation can have their tissue growth reduced ...
Influence of estrous cycle hormonal fluctuations and gonadal hormones on the ventilatory response to hypoxia in female rats
(2017-10-01)
Sex hormones may influence many physiological processes. Recently, we demonstrated that hormonal fluctuations of cycling female rats do not affect respiratory parameters during hypercapnia. However, it is still unclear ...
Serotonergic neurons in the nucleus raphé obscurus are not involved in the ventilatory and thermoregulatory responses to hypoxia in adult rats
(2013-06-15)
The medullary raphé is an important component of the central respiratory network, playing a key role in CO2 central chemoreception. However, its participation in hypoxic ventilatory responses is less understood. In the ...

Neuronal HIF-1 alpha in the nucleus tractus solitarius contributes to ventilatory acclimatization to hypoxia
(Wiley-Blackwell Publishing Ltd, 2020-05)
We hypothesized that hypoxia inducible factor 1 alpha (HIF-1 alpha) in CNS respiratory centres is necessary for ventilatory acclimatization to hypoxia (VAH); VAH is a time-dependent increase in baseline ventilation and the ...
An age- and sex-dependent role of catecholaminergic neurons in the control of breathing and hypoxic chemoreflex during postnatal development
(2020-01-01)
The respiratory system undergoes significant development during the postnatal phase. Maturation of brainstem catecholaminergic (CA) neurons is important for the control and modulation of respiratory rhythmogenesis, as well ...
