2,2′-Azobis-[2-amidinopropane] initiated lipid peroxidation of egg yolk phosphatydil choline liposomes was measured by oxygen uptake and the emitted visible luminescence. Lipid peroxidation involved a chain process (kinetic ...

Numerous investigations exist about the alterations that oxygen free radicals can provoke on biomolecules; these modifications can be prevented and/or reversed by different antioxidants agents. On the other hand, ...

Solid tumors induce an angiogenic response by the host blood vessels to form a new vascular network for the supply of fresh nutrients and oxygen responsible for tumor growth. Furthermore, tumor growth and metastatic spread ...

We prove that the prime radical rad M of the free Malcev algebra M of rank more than two over a field of characteristic not equal 2 coincides with the set of all universally Engelian elements of M. Moreover, let T(M) be ...

As part of our ongoing research on antioxidant agents from Brazilian flora, twenty extracts and fractions obtained from Pterogyne nitens Tulasne (Fabaceae) were screened for free radical scavenging activity by using ABTS ...

Diphenylmethyl radicals generated photochemically from 1,1,3,3-tetraphenylacetone (TPA) or 1,ldiphenylacetone (DPA) have been examined in vesicles using laser flash photolysis techniques. Experiments in small vesicles ...
