Breathing Emission Particles Turns HDL Cholesterol From 'Good' To 'Bad'

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.

Sounds like junk science to support the anti carbon nutcases.

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 administration’s 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…

Just asking.

"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. "

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.

What is it with this guy? His picks to lead all these various three letter agencies seem to consist of an awful lot of diesel dyke looking “women”.

It’s enough to make a grown man gag.

Remember Fairy Hardcastle in CS Lewis’ “That Hideous Strength”? There’s a slew of ‘em in this administration.

I call them also B.O.D.s - Rhymes with Witches On Duty. They are *itches by avocation, character and as a career choice.

“The experiments were conducted at EPA’s Human Studies Facility at the University of North Carolina in Chapel Hill. “That EPA administrator Lisa Jackson permitted this heinous experimentation to occur under her watch shocks the conscience,” said Milloy.”

“The 41 subjects who took part in the experiment included people who were elderly or suffering from asthma, hypertension or metabolic syndrome.” (start of the Benghazi Hussein Obama Death Panels???)

“He further alleges that none of the patients were told that breathing in such toxic fumes were life- or health-threatening.

Think back to when the War on Tobacco started

Sounds eerily familiar.

We’re going to ban Internal Combustion cars if it’s the last thing the government does.

IRS lawyer Sarah Hall Ingram received four bonuses totaling $103,390 between 2009 and 2012 while managing the tax agency's division that harassed conservative Tea Party groups seeking tax exempt non-profit status. She was then promoted to manage the IRS role in implementing Obamacare. Big bonuses like those awarded Ingram typically require presidential approval.
