Higher vitamin D levels associated with lower risk of bladder cancerhttp://www.lef.org/newsletter/2010/1102_Higher-Vitamin-D-Levels-Associated-with-Lower-Risk-of-Bladder-Cancer.htm?source=eNewsLetter2010Wk45-1&key=Article&l=0 |
An article published online on October 26, 2010 in the journal Cancer Research reveals an association between higher levels of serum vitamin D and a lower risk of bladder cancer in men. The finding adds another cancer to the list of those for which vitamin D appears to have a protective benefit. The current study involved 500 participants in the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study, a randomized, double-blinded trial of Finnish male smokers conducted to determine the effects of alpha-tocopherol and beta-carotene supplementation on cancer risk. Participants were cancer-free at the beginning of the study. Blood samples drawn upon enrollment between 1985 and 1988 were analyzed for serum 25-hydroxyvitamin D levels and other factors. The National Cancer Institute researchers compared 250 subjects who were diagnosed with bladder cancer through April, 2005 and an equal number of participants who did not have the disease. Cases and controls were matched for age and date of blood draw. A low level of vitamin D was associated with a significantly greater risk of bladder cancer. Men whose vitamin D level was less than 25 nanomoles per liter experienced a 73 percent greater adjusted risk of the disease than those whose levels were at least 50 nanomoles per liter. Similar risks were observed for those whose levels fell between 25 and less than 37.5, and from 37.5 to less than 50 nanomoles per liter. "These findings are consistent with previous cell culture, in vivo, and genetic evidence suggesting that greater exposure to vitamin D could have a role in protecting against bladder cancer," Alison M. Mondul and coauthors write. "Higher serum 25-hydroxyvitamin D may be associated with greater urinary excretion and concentration of free and conjugated vitamin D metabolites. Increased exposure of the bladder mucosa to these metabolites could promote transitional cell differentiation and apoptosis and, thus, reduce epithelial proliferation and neoplasia." "Future studies should examine the association in other populations, especially nonsmokers and women, and evaluate possible effect modification by season of blood draw, physical activity, and intake of other nutrients, including vitamin E," they recommend. |

WARNING FROM RAEL: For those who don't use their intelligence at its full
capacity, the label "selected by RAEL" on some articles does not mean that I
agree with their content or support it. "Selected by RAEL" means that I believe
it is important for the people of this planet to know about what people think or
do, even when what they think or do is completely stupid and against our
philosophy. When I selected articles in the past about stupid Christian
fundamentalists in America praying for rain, I am sure no Rael-Science reader
was stupid enough to believe that I was supporting praying to change the
weather. So, when I select articles which are in favor of drugs, anti-semitic,
anti-Jewish, racist, revisionist, or inciting hatred against any group or
religion, or any other stupid article, it does not mean that I support them. It
just means that it is important for all human beings to know about them. Common
sense, which is usually very good among our readers, is good enough to
understand that. When, like in the recent articles on drug decriminalization, it
is necessary to make it clearer, I add a comment, which in this case was very
clear: I support decriminalizing all drugs, as it is stupid to throw depressed
and sad people (as only depressed and sad people use drugs) in prison and ruin
their life with a criminal record. That does not mean that there is any change
to the Message which says clearly that we must not use any drug except for
medical purposes. The same applies to the freedom of expression which must be
absolute. That does not mean again of course that I agree with anti-Jews,
antisemites, racists of any kind or anti-Raelians. But by knowing your enemies
or the enemies of your values, you are better equipped to fight them. With love
and respect of course, and with the wonderful sentence of the French philosopher
Voltaire in mind: "I disapprove of what you say, but I will defend to the death
your right to say it".

"Ethics" is simply a last-gasp attempt by deist conservatives and
orthodox dogmatics to keep humanity in ignorance and obscurantism,
through the well tried fermentation of fear, the fear of science and
new technologies.
There is nothing glorious about what our ancestors call history,
it is simply a succession of mistakes, intolerances and violations.
On the contrary, let us embrace Science and the new technologies
unfettered, for it is these which will liberate mankind from the
myth of god, and free us from our age old fears, from disease,
death and the sweat of labour.
