Sentences with phrase «oxygen and nitrogen species»

Similarly, a problem with antioxidant production can result in the buildup of reactive oxygen and nitrogen species, otherwise termed «free radicals», in the mitochondria.

Free radicals are released by cellular mechanisms responding to impact and cardio - muscular stress - specifically reactive oxygen and nitrogen species (RONS).

Free radicals like reactive oxygen and nitrogen species (ROS, RNS) are molecules missing an electron, making them highly unstable and capable of destructive interactions with lipids, DNA, and proteins.

Not exact matches

These powerhouse organelles are major sites of oxidative stress due to the high production of reactive oxygen species ROS (reactive oxygen species) and RNS (reactive nitrogen species).

Bodamyali, T.; Stevens, C. R.; Blake, D. R.; Winyard, P. G. Reactive oxygen / nitrogen species and acute inflammation: a physiological process.

Moreover, reactive nitrogen and oxygen species (RNOS) are used extensively in cellular signalling, and cells adaptively regulate endogenous antioxidants on short time scales to respond to deletorious spikes of RNOS faster than we could ever achieve with dietary antioxidants.

Intracellular oxidative stress arises due to the imbalance in the production of reactive oxygen / reactive nitrogen species and cellular antioxidant defense mechanisms.

The mitochondria in our cells are responsible for releasing energy from the molecules in our food, but they also unleash electron - stealing free radicals like reactive oxygen and reactive nitrogen species.

This knowledge is not new; the same year as Charles Darwin published «The Origin of Species», John Tyndall, an Irish scientist, published a paper in 1859 describing how he measured the absorption of infrared radiation in his laboratory, finding that CO2 and water vapour absorbed the radiation, whereas nitrogen and oxygen, the main gases in the atmosphere, do not.

Auroral emissions typically occur at altitudes of about 100 km (60 miles) and are often green, white, or reddish in colour depending on what species (atomic oxygen, molecular oxygen, or nitrogen, respectively) is primarily emitting light.

Imagine high - tech buildings so in tune with the biosphere that they inhabit the landscape like native trees, making oxygen, sequestering carbon, fixing nitrogen, purifying water, providing habitat for thousands of species, accruing solar energy, building soil, and changing with the seasons — while also generating remarkable productivity and providing beauty, comfort, and delight.

But pollution also covers hundreds of chemicals which are fine or even beneficial at low levels but which if released in large quantities or in problematic circumstances cause «harm» — like phosphorus (grows your veges but also leads to toxic cyanobacterial blooms which kill cattle), nitrogen (grows crops kills many native species of plants and promotes weed growth costing farmers), copper (used as an oxygen carrier by gastropods but in high concentrations kills the life in sediments which feed fish), hormones like oestrogen (essential for regulating bodies but in high concentrations confuse reproductive cycles especially with marine life) or maybe molasses from a sugar mill (good for rum but when dumped into east coast estuaries used to cause oxygen sag in estuaries leading to massive fish kills).
