PROSTATE CANCER, STROKE

Prostate cancer––this study is looking at the role of zinc in prostate cancer cells.  Zinc in normal prostate cells is high and in prostate cancer cells is low.  Research for many years had shown that taking supplemental zinc in a diet does not raise the level within the cells.  In this particular study the researchers elected to use  zinc supplements in addition to resveratrol which did indeed raise the level of zinc within prostate cells returning to them the natural resistance to cancer changes which did occur in prostate cells with high zinc.  This is yet another reason why resveratrol can help prevent the onset of prostate cancer in men at high risk.  PMID 24866157

Stroke––At the University of Florida in Gainesville this study was done using mice half of which were on resveratrol.  As with other similar studies a stroke was induced by clamping off an artery to the brain.  Afterwards the amount of loss of brain tissue was measured.  In the resveratrol group the volume of brain injury was less.  There was a definite neuro protective effect as a result of being on resveratrol prior to the stroke.  PMID23758534

Stroke–this paper is a study from a medical University in Korea discussing the use of resveratrol in patients given after a stroke.  This also was a mouse study but none of these subjects  were pretreated.  A stroke was induced in all of them in by clamping an artery to the brain.  One third were given no treatment.  One third was given resveratrol 3 hours after the artificial stroke and the final third was given resveratrol 6 hours after the artificial stroke.  In both groups with resveratrol given after the stroke there was dramatically smaller infarct volume and a marked increase in early healing and new vessel formation.  This was a beneficial effect that was achieved after the injury rather than before.  PMID 20655115
