High altitude dermatology

Indian Journal of Dermatology, 2017
Approximately, 140 million people worldwide live permanently at high altitudes (HAs) and approximately another 40 million people travel to HA area (HAA) every year for reasons of occupation, sports or recreation. In India, whole of Ladakh region, part of Northwest Kashmir, Northern part of Sikkim and Tenga valley of Arunachal are considered inhabited ...

Athletes at High Altitude [PDF]

Sports Health: A Multidisciplinary Approach, 2016
Context: Athletes at different skill levels perform strenuous physical activity at high altitude for a variety of reasons. Multiple team and endurance events are held at high altitude and may place athletes at increased risk for developing acute high altitude illness (AHAI).

Association Between Plasma N-Acylethanolamides and High Hemoglobin Concentration in Southern Peruvian Highlanders

, 2017
High-altitude (HA) hypoxia is a stressful condition endured by organisms through different mechanisms. Failing to adapt to chronic HA exposure leads to a disease called chronic mountain sickness (CMS) characterized by excessive erythrocytosis (hemoglobin

Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

5-Hydroxytryptamine receptor 1D overexpression exacerbates gastric cancer proliferation, invasion, and angiogenesis by activating the Wnt/β-catenin signaling

BMC Cancer
Dysregulation of 5-Hydroxytryptamine and its receptors play important roles in the development and progression of malignant tumors. However, the biological role and underlying molecular mechanism of 5-Hydroxytryptamine Receptor 1D (HTR1D) gastric cancer (

Adropin Is a Key Mediator of Hypoxia Induced Anti-Dipsogenic Effects via TRPV4-CamKK-AMPK Signaling in the Circumventricular Organs of Rats

Frontiers in Molecular Neuroscience, 2017
Water intake reduction (anti-dipsogenic effects) under hypoxia has been well established, but the underlying reason remains unknown. Our previous report indicated that activated TRPV4 neurons in SFO are associated with anti-dipsogenic effects under ...

Identification of a miRNA–mRNA Regulatory Networks in Placental Tissue Associated With Tibetan High Altitude Adaptation

Frontiers in Genetics, 2021
The Tibetan population has lived and successfully reproduced at high altitude for many generations. Studies have shown that Tibetans have various mechanisms for protection against high-altitude hypoxia, which are probably due, at least in part, to ...

High myopia at high altitudes

Frontiers in Physiology
Background: Optic nerve sheath diameter (ONSD) increases significantly at high altitudes, and is associated with the presence and severity of acute mountain sickness (AMS). Exposure to hypobaria, hypoxia, and coldness when hiking also impacts intraocular pressure (IOP).
