Every year millions of people fly to high-altitude destinations. They thereby expose themselves to specific high-altitude conditions. The hypoxic environment (low ambient oxygen availability) constitutes a major factor affecting health and well-being at high altitude. ⋯ In addition, diminished oxygen availability impairs exercise tolerance, which not only limits physical activity at high altitude but may also provoke symptomatic exacerbation of pre-existing diseases. Moreover, the cold and dry ambient air and increased levels of solar radiation may contribute to adverse health effects at higher altitude. Thus, medical pre-examination and pre-flight advice, and proper preparation (pre-acclimatization, exercise training, and potentially adaptation of pharmacological regimes) are of utmost importance to reduce negative health impacts and frustrating travel experiences.

This study aimed to investigate the expression and prognostic significance of topoisomeraseII (Topo-II) and c-erbB-2. ⋯ In conclusion, Topo-II and c-erbB-2 are highly expressed in breast cancer and are closely related to breast cancer. Moreover, the detection of Topo-II and c-erbB-2 in serum can help diagnose gestational diabetes mellitus quickly and effectively.
