Free Radicals in Biology and Medicine

Abstract

The new edition of this well-established book is thoroughly revised and gives a comprehensive account of the role of free radicals, other reactive species (RS), and antioxidants in life, health, and disease. Chapter 1 reviews how oxygen (O2) is used by living organisms, why it can be toxic, and introduces the concept of oxygen radicals and other RS; their chemistry is detailed in Chapter 2, especially for superoxide, hydroxyl radical (including Fenton chemistry), peroxynitrite, nitric oxide, ozone, and singlet O2, with emphasis on their redox properties. Subsequent chapters detail what antioxidants can be made in vivo (e.g. superoxide dismutases, peroxiredoxins) and which can come from diet (e.g. vitamins E and C, carotenoids, and polyphenols such as the flavonoids) and how they work in vivo. The role of RS in cell proliferation, senescence, and death (e.g. by apoptosis, necrosis, or intermediate forms) is presented. Methods for measuring RS are described in detail, including electron paramagnetic resonance and biomarker determination. Useful roles for RS (e.g. cell signalling, phagocyte action), as well as systems in which they cause particular problems (e.g. premature babies, the eye, the ear) are presented. Acute and chronic inflammation are used to illustrate both roles There is a comprehensive description of the role of RS in human diseases, from cancer to heart disease to dementia, in the ageing process, and in the toxicity of many agents, from ethanol to carbon tetrachloride to paraquat. Therapeutic agents active against RS are reviewed in detail, including NADPH oxidase inhibitors, N-acetylcysteine, and Ebselen.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Diabetes causes oxidative stress, which may contribute to the increased tendency for Alzheimer disease in diabetes.

    “Diabetes also leads to oxidative stress (ref8, also see later discussion), which may make a contribution to its propensity to favour AD development9.”
  • In preclinical Alzheimer disease and Alzheimer disease brains, oxidative damage to many molecules is elevated.

    “In the brains of subjects with PCAD and AD, levels of oxidative damage to a wide range of molecules are increased8–19.”
  • Oxidative damage is a central component of Alzheimer disease pathogenesis.

    “but oxidative damage is a key component.”
  • Oxidative stress contributes substantially to the development and progression of Alzheimer disease.

    “has been shown in a wide range of studies to contribute significantly to the pathogenesis and progression of AD2,8–19.”
  • Loss of ion gradients allows extracellular calcium to enter, raising intracellular free calcium and stimulating calcium-dependent endonuclease, phospholipase, and proteinase activities, contributing to synaptic dysfunction and neuronal death.

    “Moreover, loss of ion gradients can allow extracellular Ca2+ to enter, which can further raise intracellular free Ca2+ levels, stimulating Ca2+-dependent endonuclease, phospholipase, and proteinase activities8, contributing to synaptic dysfunction and eventual neuronal death.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
