High-dose supplements of antioxidants may be linked to health risks in some cases, including higher mortality rates. For example, high doses of beta-carotene and vitamin E was found to increase the risk of lung cancer and overall mortality in smokers. [2] High doses of vitamin E may increase risks of prostate cancer and one type of stroke.
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.
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 ...
As of February 2024, it contained over 35 million research articles with full text access. The materials available come from three different forms: content identified by the Wayback Machine, by digitized print material and sources such as uploads from users and collections from partnerships.

Cancer Cell joined the cancer research and oncology communities and their call for action and change by dedicating its September 2020 issue to the importance of diversity and immigration in cancer research in the U.S. and publishing a series of opinion pieces by scientists and clinicians that represent several minorities (immigrants, Black ...
The first issue of Clinical Cancer Research was published in January 1995. [2] By 1 December 1994, 128 manuscripts had been submitted for publication by investigators representing a variety of clinical and laboratory disciplines not only from the United States but also from the international research community. In 1998, the number of ...
Early research on the role of antioxidants in biology focused on their use in preventing the oxidation of unsaturated fats, which is the cause of rancidity. [7] Antioxidant activity could be measured simply by placing the fat in a closed container with oxygen and measuring the rate of oxygen consumption.
