Effects of Ascent to High Altitude on Human Antimycobacterial Immunity [PDF]
PLoS ONE, 2013 عدوى السل والمرض والوفيات كلها أقل شيوعًا عند الارتفاعات العالية من الارتفاعات المنخفضة وكان الصعود إلى الارتفاعات العالية موصى به تاريخيًا للعلاج. الآليات المناعية والفطرية الكامنة وراء الارتباط بين الارتفاع والسل غير واضحة. درسنا آثار الارتفاع على المتفطرات والمناعة المضادة للبكتيريا.

Effects of Hypoxemia by Acute High-Altitude Exposure on Human Intestinal Flora and Metabolism [PDF]
Microorganisms, 2023 This study examined the effects of hypoxemia caused by acute high-altitude hypoxia (AHAH) exposure on the human intestinal flora and its metabolites. The changes in the intestinal flora, metabolism, and erythropoietin content in the AHAH population under altitude hypoxia conditions were comprehensively analyzed using 16S rRNA sequencing, metabonomics ...

Introgressive Hybridization and Hypoxia Adaptation in High-Altitude Vertebrates
Frontiers in Genetics, 2021 In natural populations of animals, a growing body of evidence suggests that introgressive hybridization may often serve as an important source of adaptive genetic variation.

High-Altitude Living Shapes the Skin Microbiome in Humans and Pigs
Frontiers in Microbiology, 2017 While the skin microbiome has been shown to play important roles in health and disease in several species, the effects of altitude on the skin microbiome and how high-altitude skin microbiomes may be associated with health and disease states remains ...

Recent Observations of Human-induced Asymmetric Effects on Climate in Very High-Altitude Area
PLoS ONE, 2014 Like urban heat islands (UHI), human-induced land degradation (HLD) is a phenomenon attributed to human activities, but this phenomenon occurs in non-urban areas. Although a large body of work has demonstrated that land-cover change influences local climate systems, little work has been done on separating the impact of HLD from naturally-occurring ...

Adrenal, thyroid and gonadal axes are affected at high altitude
Endocrine Connections, 2018 Humans cannot live at very high altitude for reasons, which are not completely understood. Since these reasons are not restricted to cardiorespiratory changes alone, changes in the endocrine system might also be involved.

Effects of High Altitude on Lipid Components of Human Serum
Experimental Biology and Medicine, 1968 SummarySerum lipid components were measured in eight male subjects exposed to an altitude of 14,000 feet for 14 days. Concentrations of total lipids rapidly decreased after the third day of exposure and a similar, although less pronounced decrease was observed in cholesterol levels.
