The mechanisms underlying the low incidence of myopia at high altitudes remain unclear. Choroidal thickness and the dopaminergic system have been shown to be closely associated with myopia development. This study aimed to investigate the effects of high altitude exposure on choroidal thickness and the dopaminergic system.

The Byers Peninsula, the largest ice-free area in Maritime Antarctica, is vital for studying landscape-scale natural processes due to its diverse periglacial landforms. This study aim to characterize the soils and environments of its southern sector, focusing on soil-landform-lithology interactions. Thirty-seven soil profiles were classified, collected, and chemically and physically analyzed.

In this study, whole genome sequence data of Ladakhi cattle from high altitude region of Leh-Ladakh and Sahiwal cattle from arid, semi-arid tropical region were compared. To gain a deeper understanding of the selective footprints in the genomes of Ladakhi and Sahiwal cattle, two strategies namely run of homozygosity (ROH), and fixation index (F) were employed. A total of 975 and 1189 ROH regions were identified in Ladakhi and Sahiwal cattle, respectively.

In Mexico, Neospora caninum and Toxoplasma gondii are major causes of reproductive problems in sheep. Understanding the environmental factors that influence the spread of these parasites is crucial for developing effective control strategies. The objective of this study was to identify the environmental factors associated with N.

In certain people, the number of red blood cells continues to grow, resulting in high altitude polycythemia (HAPC) which is characterized by headache, disorientation, sleeplessness, and bone discomfort. HAPC is often associated with multiple complications, of which lower extremity arteriosclerosis obliterans (LEASO) is rare.
