Estrogen, estrogen-like drugs' ability to protect brain after stroke under study
...ems a natural fit because estrogen and some of its metabolites
have been shown in many systems to be a free-radical scavenger. Dr. Brann's preliminary studies support this, showing dramatically reduced levels of toxic superoxide, the major free radical, in stroke models treated with estrogen and tamoxifen before...

Vitamin D and calcium supplements have varied effects on breast cancer risk
...wski explained that "planned analyses of vitamin D metabolites
in the blood may help interrupt the findings." Previous observational studies have suggested that vitamin D and calcium may protect against breast cancer. Because natural sources of vitamin D are limited (mostly sun exposure and oily fish), vitamin D...
