Noun1.free radical- an atom or group of atoms with at least one unpaired electron; in the body it is usually an oxygen molecule that has lost an electron and will stabilize itself by stealing an electron from a nearby molecule; "in the body free radicals are high-energy particles that ri...
Interventive strategies such as soluble receptors for AGEs and effective antioxidants might become important therapeutic strategies in the near future.John Wiley & Sons, Ltd.Australasian Journal on AgeingStaehelin, HB: Free radicals and glyoxidative stress in ageing and age-rrelated diseases.

Oxygen free radicals have been hypothesized to play an important role in the process of aging. To investigate the correlation between oxidative stress and accumulation of DNA damage we determined age-dependent levels of activities eliminating 8-oxoguanine, hypoxanthine and uracil from DNA in liver cel...
Enzymes can make the active oxygen free radicals in the body become less reactive, thus weakening their ability to attack the body. The enzymes defense is limited to cells, and antioxidants are found in cell membranes and 19、 some outside the cell. These substances lie deep in our bodies,...
Boston, MA—Scientists have found that free radicals (unstable molecules that cause the death of cells as the body ages) may also cause the damage in the eyes of patients with Fuchs Endothelial Corneal Dystrophy (FECD), a hereditary disease that is one of the...
Testing for germline mutations in SDH is recommended in patients with WT GIST. These findings highlight a potential central role of SDH dysregulation in WT GIST oncogenesis. 展开 关键词: biology and medicine radiation effects air beans chromosomes free radicals hydrogen peroxides hydroxides iron ...
Free radicals and other so-called ‘reactive species’ are constantly produced in the brainin vivo. Some arise by ‘accidents of chemistry’, an example of which may be the leakage of electrons from the mitochondrial electron transport chain to generate superoxide radical (O2−). Others are g...
activity- the trait of being active; moving or acting rapidly and energetically; "the level of activity declines with age" activeness trait- a distinguishing feature of your personal nature brio,invigoration,spiritedness,vivification,animation- quality of being active or spirited or alive and vigorous...
afOxidation means to decay or age. It results from regular function of metabolism and cell function. In the human body, oxidation causes free radical damage. Free radicals that exist in our body grab an electron from one of our cells to become stable and in the process damage the DNA of ...
Billions of free radicals are being produced in the body at any time. Our attitude and state of mind can actually contribute to our level of oxidative damage. For example each molecule of adrenaline produces two oxygen radicals as it metabolizes in the body, therefore too much stress can incr...
