carry off on the megadoses of antioxidant vitamin like C and E. A study by researcher at Cedars - Sinai Heart Institute shows that you may overdose on these health aids , and the consequence could be mutated base cells that cause genus Cancer .
There ’s no cause for dismay if you ’re staying within evoke loony toons of your vitamins or nutritionary supplements . This study looked only at what happens when mass take much more than the standard measure of antioxidants .
Researcher Eduardo Marbán and his colleague ’ stumbled on the antioxidant problem while they were researching tissue engineering for human hearts . Using stem mobile phone , Marbán and his squad are work on a mode to develop heart tissue to renovate price do by heart attacks . patient role who suffer from damaged core undergo two quick procedure : First , the researchers collect a few cadre from the affected role ’ tenderness that will be used to grow the replacement tissue paper ; Second , the new tissue is injected , with no dangers of rejection since it ’s develop from the patient role ’ own physical structure .
According to a release about their project :
Marbán and his team by chance disclose the danger of excessive antioxidant doses while seeking a way to reduce the genetic abnormalities that occurred naturally when the scientist sought to multiply human cardiac stem cells . . . In laboratories , stem turn cells are often grown in a Petri dish culture than is compose of 20 percent oxygen , whereas cells growing inside human tissue paper are exposed to just 3 to 5 percent oxygen . But Marbán ’s squad of research worker became frustrated because the higher concentration of atomic number 8 in lab - grown stem cellular telephone resulted in 9 percent of the cells being rejected because of genetic abnormalities .
“ We sought to anticipate that oxidisation trouble by supply high doses of antioxidants at once to the cell , ” Marbán said . “ That ’s when we made the serendipitous discovery that there is a danger zone for the cell exposed to antioxidants to develop genetical abnormalities that predispose to genus Cancer . ”
This is in force to be intimate , but when will we find out the really coolheaded stuff , like whether this project to revivify damaged hearts will work ? Clinical trial results on the heart subroutine are expected in former 2011 , so you might have a warmness repaired with shank cellphone as early as 2012 .
