Action of phenolic derivatives (acetaminophen, salicylate, and 5-aminosalicylate) as inhibitors of membrane lipid peroxidation and as peroxyl radical scavengers.

Archives of Biochemistry and Biophysics, 1994
The action of the phenolic compounds acetaminophen, salicylate, and 5-aminosalicylate (5-ASA) as inhibitors of lipid peroxidation was studied under conditions suitable for establishing their antioxidant potencies.

Development and validation of an improved oxygen radical absorbance capacity assay using fluorescein as the fluorescent probe.

Journal of Agricultural and Food Chemistry, 2001
An improved method of oxygen radical absorbance capacity (ORAC) assay has been developed and validated using fluorescein (3',6'-dihydroxyspiro[isobenzofuran-1[3H],9'[9H]-xanthen]-3-one) as the fluorescent probe.

The Persistent Radical Effect in Organic Synthesis.

Angewandte Chemie, 2019
Radical-radical couplings are mostly nearly diffusion controlled processes. Therefore, the selective cross-coupling of two different radicals is challenging and not a synthetically valuable process.

Radical generation by the interaction of transition metals with common oxidants.

Environmental Science and Technology, 2004
Nine transition metals were tested for the activation of three oxidants and the generation of inorganic radical species such as sulfate, peroxymonosulfate, and hydroxyl radicals.

Radical Fashion and Radical Fashion Innovation

Journal of Global Fashion Marketing, 2010
This is a study of the related concepts of radical fashion and radical fashion innovation. Radical fashions are defined here as those that may never enter the market at all, and exist primarily on runway shows, in exhibitions and in publicity; by contrast, radical fashion innovations may be very successful in the marketplace. Radical fashions represent

How radical is radical realism?

European Journal of Philosophy, 2021
AbstractRadical realism is distinguished in part from other forms of political realism by its more explicit anti‐status quo objectives. In particular, radical realists generally reject the legitimacy of liberal political institutions, and often defend some version of Marxism or anarchism. However, critics of radical realism sometimes argue that radical

Generation and Radical–Radical Cross-Coupling of Alkenyloxy Radical

Organic Letters
Alkene-attached oxygen radicals are rarely used, as highly reactive oxygen radicals are incompatible with the alkene moiety. The direct radical-radical cross-coupling of O radicals is also challenging (limited to N-O bond formation) because of the lack of suitable persistent radical species.
