Breathing Emission Particles Turns HDL Cholesterol From
'Good' To 'Bad'
Article Date: 18 May 2013
Academic researchers have found that breathing motor vehicle emissions triggers a change in high-density lipoprotein (HDL) cholesterol, altering its cardiovascular protective qualities so that it actually contributes to clogged arteries.
In addition to changing HDL from "good" to "bad," the inhalation of emissions activates other components of oxidation, the early cell and tissue damage that causes inflammation, leading to hardening of the arteries, according to the research team, which included scientists from UCLA and other institutions.
The findings of this early study, done in mice, are available in the online edition of the journal Arteriosclerosis, Thrombosis and Vascular Biology, a publication of the American Heart Association, and will appear in the journal's June print edition.
Emission particles such as those from vehicles are major pollutants in urban settings. These particles are coated in chemicals that are sensitive to free radicals, which have been known to cause oxidation. The mechanism behind how this leads to atherosclerosis, however, has not been well understood.
Gina McCarthy, the president's pick to lead the EPA
More BS science!
It will also kill you if you close the windows and plug the muffler.
Sounds like junk science to support the anti carbon nutcases.
So my high cholesterol isn’t from the cheese, the 16 oz porterhouse, chocolate cake w/ ice cream....Yeh!!!!
Oh, God. Antoher DIESEL DYKE in government, the type well-suited to jack-booted thuggery in government.
Congress Now Set To Investigate Obama EPA Scandal
by Ulsterman on May 18, 2013
Another scandal is now set to hammer the Obama White House this time detailing how the Obama administrations Environmental Protection Agency abused its authority to give favorable treatment to liberal groups while at the same time attempting to hinder or punish conservative organizations. Yet more proof of tyrannical government in the Age of Obama

Is every one of Obama’s female picks a Lesbian?
Just asking.
I bet Big Sis recommended her fr the position.

Who is this guy?
So I should leave my bike at home and drive a car to work to be healthier?
"Hey Obama. Stop killing us with your EPA stuides!"
"Mice were exposed for a few hours, several days a week, to whole diesel exhaust at a particulate mass concentration within the range of what mine workers usually are exposed to. After the exposures, UCLA scientists analyzed blood and tissue specimens and checked to see if the protective antioxidant and anti-inflammatory properties of HDL, known as "good" cholesterol, were still intact. "
Did they make those finding during these experiments?

Yep
I smell big rats here. A comment to the article:
Based on this article, this research was unfocused, at best. “Vehicle emissions” include hydrocarbons, particulate matter, nitrogen oxides, carbon monoxide, sulfur dioxide, benzene, acetaldehyde, and 1,3-butadiene. With the exception of CO, emissions of these components are generally higher from diesel than gasoline engines.
“Mice were exposed for a few hours, several days a week, to whole diesel exhaust at a particulate mass concentration within the range of what mine workers usually are exposed to.”
Extrapolating this to humans not working in mines, most of whom have minimal exposure to diesel exhaust in far lower concentrations, is a stretch.
