Carbon Nanoparticles Break Barriers--and That May Not Be Good http://apocadocs.com/s.pl?1316129043
A study by researchers from the schools of science and medicine at Indiana University-Purdue University Indianapolis examines the effects of carbon nanoparticles (CNPs) on living cells. This work is among the first to study concentrations of these tiny particles that are low enough to mimic the actual exposure of an ordinary individual...The research, published in the September 2011 issue of the journal Nanotoxicology, focuses on the effect of low concentration CNP exposure on the cells that line the renal nephron, a tubular structure inside the kidney that makes urine. The investigators found the role of the CNPs in this part of the body to be significant and potentially worrisome....["]We found that these minute particles cause leakage in the cellular lining of the renal nephron," said study first author Bonnie Blazer-Yost, Ph.D. ..."Breaching this biological barrier concerns us because things that should be retained in the forming urine can leak back into the blood stream and things in the blood can leak into the urine. Normal biological substances as well as waste products are dangerous if they go where they are not supposed to be," Blazer-Yost said.
