Air temperature, ground surface temperature (GST; 0 cm at depth), precipitation and freezing depth data at 50 meteorological stations in the Qinghai–Tibet Plateau (QTP) were analyzed to examine changes of climate and seasonally frozen ground (SFG) in the past 30 years. The latitude, longitude, elevation, mean annual air temperature (MAAT), annual precipitation (AP) and maximum freezing depth at...

The recent range expansion of human babesiosis in the northeastern United States, once found only in restricted coastal sites, is not well understood. This study sought to utilize a large number of samples to examine the population structure of the parasites on a fine scale to provide insights into the mode of emergence across the region. 228 B. microti samples collected in endemic northeastern...

The regional hydrology and ecosystems of the northeastern margin of the Qinghai–Tibetan Plateau have changed over the past 40 years driven by intense human activity and regional climate changes. Annual mean air temperature has increased in the region. Streamflow from the northeastern margin of the Qinghai–Tibetan Plateau has decreased significantly. Overall, a number of Alpine step meadows and ...

introduction and aims: the northeastern region of iran has some of the highest rates of esophageal squamous cell carcinoma (escc) in the world. materials and methods: to investigate the role of polycyclic aromatic hydrocarbons (pahs) in the etiology of escc in northeastern iran, we measured urine 1-hydroxypyrene glucuronide (1-ohpg), a stable pah metabolite, in 99 inhabitants of this area. resu...
