Summary: This study uses data from the Visible Infrared Imaging Radiometer Suite on the Suomi National Polar-orbiting Partnership to derive the normalized water-leaving radiance spectra in high-altitude lakes over the Tibetan Plateau. The study reveals significant diversity in the optical properties of these lakes, posing challenges to the development of remote sensing algorithms for water biological and biogeochemical products in the region.

Summary: High altitude exposure affects neuromuscular fatigability, with acute exposure increasing fatigue compared to sea level and chronic exposure leading to partial restoration of supraspinal fatigue. Native highlanders show superior performance and lesser neuromuscular fatigability compared to acclimatized lowlanders at altitude.

Summary: The polar regions are highly exposed to secondary particles and radiation from primary cosmic rays in the atmosphere due to their weak geomagnetic shielding. The radiation flux of secondary particles is enhanced at high-altitude regions, such as mountains in Antarctica, compared to sea level due to reduced atmospheric attenuation. This study presents measurements of the radiation background at the high-mountain Antarctic station Vostok and compares them with a Monte Carlo-based model for cosmic ray propagation and assessment of the radiation field. The results show that the annual dose equivalent at high-altitude Antarctic facilities can exceed the established limit for the general population.

Summary: The study investigated the abundance and distribution of microplastics in water bodies and sediments at the Qinghai-Tibet Plateau. Microplastics were found in all samples, with higher concentrations in areas with poor water quality and lower altitudes, but smaller sizes were found at higher altitudes.

Summary: The study found that a significant amount of microplastics can be found in surface waters and sediments in the Tibetan Plateau, mainly in the form of fibers ranging from 100 to 500 micrometers. The concentration of microplastics in the downstream of the Brahmaputra River nearly doubled compared to the upstream, largely due to human activities downstream.

Summary: This study characterized viruses from high altitude lakes on the Tibetan Plateau, revealing differences in viral abundance, population size, and morphology among lakes, as well as identifying a novel viral group. These variations are likely influenced by lake evolution, water source, and environmental conditions.

Summary: This study used stable isotopes to investigate the spatiotemporal patterns of water sources for Faber's fir in a high-altitude elevational gradient on the Tibetan Plateau. The results showed that the dependence on water sources varied with elevation, and precipitation contributed significantly to xylem water.

Summary: High-altitude plants are a rich source of secondary metabolites with anti-fatigue properties. These plants have gone through natural selection and co-evolution and are widely used in highland regions. The active compounds in these plants show therapeutic potential for fatigue and related disorders.

Summary: A driver fatigue test was conducted using the Kangtai PM-60A car heart rate and oxygen tester to collect drivers' heart rate oximetry in National Highway 214 in Qinghai Province. The study aims to derive the degree of driving fatigue in high-altitude areas. The results provide an empirical basis for designing antifatigue strategies to improve highway safety in high-altitude areas.

Summary: This study investigated the distribution of microplastics (MPs) in different land use patterns in the western area of the Tibetan Plateau. The results showed that altitude was the most important driving factor affecting MPs distribution, with higher abundances of small-sized MPs at higher altitudes. Traffic behavior, such as parking and rest behavior beside roads, was identified as an important source of MPs in the plateau area.

Summary: This study collected solar radiation data in the Qinghai-Tibet Plateau and developed a calculation model to estimate and adjust ground surface temperature. The results showed good agreement with existing data and reflected the variations in ground surface temperature on different underlying surfaces. This is significant for research on energy exchange in permafrost regions.

Summary: Patients with cerebral small-vessel disease (CSVD) at high altitude exhibit more severe white matter hyperintensities (WMH), fewer acute cerebrovascular events, and less lacunes in neuroimaging compared to those at low altitude.

Summary: This study investigates the expression of the protein HBD in the lungs of plateau pikas and finds that when HBD expression is downregulated, the pikas show hypoxemia. These findings provide insights into the adaptive mechanisms of plateau pikas in high-altitude environments.

Summary: With the phase-out of brominated flame retardants, the use of organophosphate esters (OPEs) has increased as alternative options. This study investigated the sources and distribution of OPEs in Laohugou Glacier No. 12 on the northeastern edge of the Tibetan Plateau. The results showed that OPEs concentrations increased with altitude and were primarily derived from traffic emissions. Backward trajectory analysis indicated that these OPEs might have come from urban emissions northwest of the glacier.
