The mean hemoglobin level of persons of Tibetan ancestry living at 4000 m in the Nepal Himalayas was found similar to that expected at an altitude of 2300 m and an arterial O2 saturation of 92%. Plasma volumes were normal, and deficiency states and hemoglobinopathies were not significant. Possible reasons for this finding are discussed.

Glaciers provide multiple ecosystem services (ES) to human society. Due to the continued global warming, the valuation of glacier ES is of urgent importance because this knowledge can support the protection of glaciers. However, a systematic valuation of glacier ES is still lacking, particularly from the perspective of ES contributors.

Accurate quantifying of methane (CH) emissions is a critical aspect of current research on regional carbon budgets. However, due to limitations in observational data, research methodologies, and an incomplete understanding of process mechanisms, significant uncertainties persist in the assessment of wetland CH fluxes in China. In this study, we developed a machine learning model by integrating measured CH fluxes with related environmental data to produce a high-resolution (1 km) dataset of CH fluxes from China's wetlands for the period 2000-2020.

Ethnopharmacological Relevance: Syringa oblata Lindl (ZDX) is a plant in the Oleaceae family that is the primary ingredient in the classic Tibetan medicine AKARU sinensis. The plant's stem is used as a medicine, and Tibetan doctors often use it as a sedative, a use with a history of nearly 100 years. Tibetan medicine mainly uses lilac to treat headache, forgetfulness, insomnia, irritability and other symptoms.

Ethnopharmacological Relevance: Originally formulated to mitigate high-altitude sickness, Xinnaoxin capsules (XNX) are composed of three traditional Chinese medicines (Rhodiola rosea L., Lycium barbarum L. and Hippophae rhamnoides) with properties of anti-hypoxia, anti-fatigue, and anti-aging.

The effectiveness of protected areas in mitigating human impacts remains uncertain due to limited in-situ data; however, atmospheric micropollutant deposition in alpine lakes may provide a quantitative approach to evaluate anthropogenic pressures and threats. In this study, the temporal changes of polycyclic aromatic hydrocarbons (PAHs) inside/outside the Siling Co protected area, Tibet were reconstructed. The varying anthropogenic impact history suggested that, unlike the dominance of residential activities (i.
