A professor has demonstrated for the first time the value of linear particle accelerators for the generation of free radicals inside biological samples. This work will have important applications throughout biochemistry, especially for researchers studying antioxidants and photosynthesis....
How much vitamin D can boost memory, learning and decision-making in older adults, and how much is too much A unique study found that overweight and obese older women who took more than three times the recommended daily dose of vitamin D showed improvements in memory and learning -- but also had slower reaction times. The researchers hypothesize that slower reaction times may increase the risk of falling among older people....
Greater levels of specific antioxidants were associated with particular colorations of tomato fruit. These genotypes could be used either directly as food or in breeding programs to recover greater levels of functional compounds such as carotenoids, tocopherols, anthocyanins, and vitamin C....
Few multivitamin products for children supply the recommended dose of 400 IU a day of vitamin D, suggest the results of a survey of 91 different products....
A new study has reported for the first time that vitamin D can be measured in human hair. This is a major step forward in assessing vitamin D status, potentially one of the major innovations in vitamin D measurement....
The bone marrow disease myelofibrosis is stimulated by excessive signaling from vitamin D and immune cells known as macrophages, reveals a research team. These findings could help to develop alternative treatments that do not target problem genes....
