Free Radical Biology and Medicine is a peer-reviewed scientific journal and official journal of the Society for Redox Biology and Medicine.The journal covers research on redox biology, signaling, biological chemistry and medical implications of free radicals, reactive species, oxidants and antioxidants.
Antioxidants are helpful in reducing and preventing damage from free radical reactions because of their ability to donate electrons which neutralize the radical without forming another. Vitamin C, for example, can lose an electron to a free radical and remain stable itself by passing its unstable electron around the antioxidant molecule.
There can be many years between promising laboratory work and the availability of an effective anti-cancer drug: Monroe Eliot Wall discovered anti-cancer properties in Camptotheca in 1958, but it was not until 1996 – after further research and rounds of clinical trials – that topotecan, a synthetic derivative of a chemical in the plant, was ...
With the specific characteristics, the MDA-MB-453 cell cancer line is now classified as a Triple Negative Breast Cancer cell line model. [1] One study suggests that the MDA-MB-453 cell line is not the best model for an apocrine breast cancer model. During the experiment, there was a mutation in the K-RAS gene that was not previously identified ...
On the contrary, research indicates that although polyphenols are antioxidants in vitro, antioxidant effects in vivo are probably negligible or absent. [3] [4] [5] By non-antioxidant mechanisms still undefined, polyphenols may affect mechanisms of cardiovascular disease or cancer. [6]
Although research in vitro indicates polyphenols are good antioxidants and probably influence the ORAC value, antioxidant effects in vivo are probably negligible or absent. [3] [10] By non-antioxidant mechanisms still undefined, flavonoids and other polyphenols may reduce the risk of cardiovascular disease and cancer. [11]
Antioxidants is a peer-reviewed open-access scientific journal that covers various areas of antioxidants research, including biosynthesis, pharmacodynamics, and synthetic antioxidants. It is published by MDPI and was established in 2012. The editor-in-chief is Stanley Omaye (University of Nevada).
It is difficult to evaluate the physiological effects of specific natural phenolic antioxidants, since such a large number of individual compounds may occur even in a single food and their fate in vivo cannot be measured. [1] [6] [8] Other more detailed chemical research has elucidated the difficulty of isolating individual phenolics.
