To the best of our knowledge, there is virtually no information in long term intermittent hypoxia conditions, the majority of evidence coming from OSA studies [ 20], where low oxygen levels are maintained for very brief periods.
The effects of training persist for several weeks or months, as opposed to adaptation, which is maintained only for brief periods [ 8].
Hypoxia-related diseases are well characterized in people living at high altitude (chronic hypoxia, CH) [ 1] and in obstructive sleep apnea (OSA), where hypoxic conditions are maintained intermittently for brief periods [ 2].
(D) Solution obtained after stirring is maintained for 15 min. On the basis of the aforementioned brief review, we herein investigate the assembly behavior of H2TPyP via a process similar to that for ZnTPyP [39].
However, when brief potentiostatic steps (84 and 200 s) were conducted at more negative potentials (−1.2 V vs Ag|AgCl), the CO2 reduction selectivity could be switched from CH4 to CO, and maintained for at least 2 hours.
Brief application of glutamate produced an increase in the number of overlapping structures within 10 min (F[1,38] = 6.06, p<0.05 compared to saline control), which was then maintained for 3 hrs (F = 16.43, p<0.01).
Brief application of glutamate produced an increase in the number of small structures within 10 min (F[1,108] = 5.30, p<0.05 compared to saline control), which was then maintained for 3 hrs (F = 7.01, p<0.01).
Cold exposure was maintained for another hour.
Maintaining bronchial artery sub-total occlusion for brief periods would increase vector transfer to the bronchial tissue and a reduced total flow mediated wash out of the vector into the heart.
But of course we will maintain a watching brief".
