Nocturnal hypoxemia, blood pressure, vascular status and chronic mountain sickness in the highest city in the world

Annals of Medicine, 2022
Introduction Chronic mountain sickness (CMS) is a condition characterized by excessive erythrocytosis in response to chronic hypobaric hypoxia. CMS frequently triggers cardiorespiratory diseases such as pulmonary hypertension and right or left heart ...

Conflict, Claim and Contradiction in the New Indigenous State of Bolivia [PDF]

, 2012
Recent conflict between indigenous people and a self-styled indigenous state in Bolivia has brought to the fore some of the paradoxes and contradictions within the concept of indigeneity itself. The contemporary politics of state sponsored indigeneity in

Downregulation of EPAS1 and EGLN1 mRNA Expression Associated With High‐Altitude Adaptive Genetic Variants in Sherpa Highlanders

Annals of Human Genetics, EarlyView.
ABSTRACT Background and Aims Sherpa highlanders exhibit remarkable tolerance to hypoxia, most likely due to genetic adaptations shaped by natural selection at high altitude. This study examined the roles of endothelial PAS domain protein 1 (EPAS1) and egl‐9 family hypoxia‐inducible factor 1 (EGLN1) in the genetic mechanisms underlying this adaptation ...

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 ...

Elevational variation in heart mass and suppression of hypoxia‐induced right ventricle hypertrophy in Andean leaf‐eared mice (Phyllotis)

The Journal of Physiology, EarlyView.
Abstract figure legend In lowland mammals that ascend to high elevation, hypoxia‐induced changes in the pulmonary circulation can give rise to hypoxic pulmonary hypertension (HPH) and associated right‐ventricle (RV) hypertrophy. Andean mice with broad elevational ranges have greater heart mass relative to body size at higher elevations, but they ...

Mitochondrial physiology in cardiac muscle of deer mice native to high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude deer mice exhibited evolved changes in mitochondrial energy metabolism and reactive oxygen species (ROS) management that may support cardiac performance under cold hypoxic conditions. High‐altitude mice had increased activity of lactate dehydrogenase (LDH) in the heart, probably enhancing the capacity for lactate ...
