He is best known for his ground - breaking discovery of the HIF - 1 (hypoxia - inducible factor 1) protein, which controls genes in response to changes in oxygen availability.

Not exact matches

The present review evaluates the evidence for such a complex system by investigating studies in which interventions such as elevated temperature, altered oxygen content of the air, reduced fuel availability and misinformation about distance covered have resulted in alterations to the pacing strategy.
If the exercise work rate is free to vary, then experimental interventions such as changes in ambient temperature, oxygen content of the inspired air, energy substrate availability or the provision of incorrect distance feedback all alter the power output (pacing strategy), whereas the rate of increase in RPE has been found to be similar between conditions.13 20 21 24 — 26

Dr. Simon's research is focused on how cells sense and respond to changes in the availability of molecular oxygen and nutrients.
For the fetus, limitations in nutrient and oxygen availability cause progressive oxidative stress which prompt the release of proteins into the maternal bloodstream in an effort to improve circulation.
His research team envisions a series of interacting processes, or feedbacks, that maintained oxygen at very low levels principally by modulating the availability of life - sustaining nutrients in the ocean and thus oxygen - producing photosynthetic activity.
While we already knew that plant roots were capable of sensing many individual soil characteristics (water, nutrients and oxygen availability), we did not have any understanding of how they integrated these signals in order to respond in an appropriate way.
Known as the Antarctic Bottom Waters (AABW), these deep, cold waters play a critical role in regulating circulation, temperature, and availability of oxygen and nutrients throughout the world's oceans.
As a result, the frigid flow plays a critical role in regulating circulation, temperature, and availability of oxygen and nutrients throughout the world's oceans, and serves as both a barometer for climate change and a factor that can contribute to that change.
The paleoclimate data, which included mainly changes in the oxygen isotopes of the calcium carbonate deposits, were then compared to similar records from other caves, ice cores, and sediment records as well as model predictions for water availability in the Middle East and west central Asia today and into the future.

However, this study suggests that this evolutionary event is tied to the availability of oxygen in the atmosphere.
Deficiencies of B12, B6, folic acid and / or iron can all create a shift in fuel availability (specifically in glycolysis: the oxidation or burning of sugar / glucose) which is a huge stressor on the body as it decreases oxygen availability to every cell.
The cellular respiration process that converts your food energy into ATP is in large part dependent on the availability of oxygen.

Oxygen availability is a vital component in muscle function and particularly important in aiding muscular recovery.
Joel Jameson has stated in order to improve the aerobic energy system we need to improve the oxygen supply, oxygen utilisation and the substrate availability.
These likely compromise overall blood flow and result in hypoxia (a reduced availability of oxygen).
In addition to increasing the quantity of organic carbon and reducing the availability of oxygen, eutrophication may also affect the overall quality of organic matter for fueling CH4 - producing archaea.
Projected changes in physical and biogeochemical drivers such as temperature, CO2 content and acidification, oxygen levels, the availability of nutrients, and the amount of ocean covered by ice, will affect marine life.
