Astaxanthin is present in most red-coloured aquatic organisms. [10] The content varies from species to species, but also from individual to individual as it is highly dependent on diet and living conditions. [16] Astaxanthin and other chemically related asta-carotenoids have also been found in a number of lichen species of the Arctic zone.
Eric A. Johnson is a microbiologist and an academic.He is a retired Professor of Bacteriology from the University of Wisconsin-Madison, serving from 1985 to 2020. [1]Johnson, most known for his research on Clostridium botulinum and its neurotoxins in food and industrial microbiology, has developed physiochemical-based methods for basic and applied research of Clostridium botulinum and ...
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 ...
Astaxanthin – Anthocyanins: 8.5 fold improvement in pharmacokinetics over the complex-free anthocyanins Lycopene – 50 mg phosphatidylcholine: improvement of lycopene pharmacokinetics by 8 fold in patients with coronary heart disease [ 46 ]
Medical research for cancer begins much like research for any disease. In organized studies of new treatments for cancer, the pre-clinical development of drugs, devices, and techniques begins in laboratories, either with isolated cells or in small animals, most commonly rats or mice. In other cases, the proposed treatment for cancer is already ...
His use of bioassay was able to discover that administration of gradually increasing dose of diphtheria in animals stimulated production of antiserum. [ 9 ] One well known example of a bioassay is the "canary in the coal mine" experiment. [ 10 ]
The chemical structure of cryptoxanthin.Xanthophylls typically present oxygen as a hydroxyl group. Thin layer chromatography is used to separate components of a plant extract, illustrating the experiment with plant pigments that gave chromatography its name.
The criteria were published in February 2000 by an international collaboration including the European Organisation for Research and Treatment of Cancer , National Cancer Institute of the United States, and the National Cancer Institute of Canada Clinical Trials Group.
