Growing evidence indicates that repeated-maximal intensity exercise in hypoxia induces larger improvement in repeated-sprint ability than in normoxia
(Brocherie et al.
Accompanied with overexpression of HIF-1a , the myotube formation and the expressions of MyoD, myogenin, and MHC were inhibited by hypoxia, while no differences were observed between HIF-1a knockdown myoblasts and the control ones under normoxia
at day 6 of myogenesis.
Kinetics of oxygen uptake for submaximal exercise in hyperoxia, normoxia
, and hypoxemia.
After incubation under normoxia
or hypoxia for 24-48 h, non-invasive cells present on the upper surface of the membrane were scraped with cotton swabs and the invasive cells present on the lower side of the membrane were fixed with ice cold methanol, stained with 0.
These works demonstrated that cells under hypoxia generate more mitochondrial ROS than those under normoxia
All animals were exposed to 4 cycles of 96 h of hypobaric hypoxia followed by 96 h of normobaric normoxia
for 32 days.
, hypoxia), which directly influences the [beta]b as a result, the content of [O.
Student's t-tests (or a Welch-Satterthwaite t-test when groups did not show equal variance) were used to assess differences in hemocyanin concentration between the time-matched normoxia
control and hypoxia treatment groups within each species.
tisular, la HIF-[alfa] es hidroxilada por las enzimas propil (tipo PHD-2) y la asparagil (tipo FIT-1) hidroxilasas y luego es marcada por una ubiquitina, la proteina de von Hippel-Lindau (pVHL); finalmente es degradada por el proteosoma.
There are a variety of mechanisms of nitrite reduction to NO and it is now appreciated that this process, while being enhanced under hypoxic conditions, also occurs under normoxia
[4, 20, 21].
Three physiological states (hyperoxia, normoxia
, and hypoxia) were induced by changing oxygen concentration in the inhaled gases.
For the second single-hypoxic cycle (trial 2), the scallops recovered under normoxia
for 3 h after the initial escape responses were evaluated, and we then proceeded as in trial 1 (i.
