"I being a diesel freak, see that gas is the only way to go..."
Asthmatics who inhaled diesel exhaust fumes for two hours in a study booth didn’t just get itchy eyes and a headache while breathing in the polluted air.
They also experienced effects on a micro level as genes associated with inflammatory and oxidative stress processes were altered.
Those are the findings from five researchers at the University of B.C. who put 16 asthma patients in a cubicle, exposing them — on separate occasions — to filtered air and diesel exhaust and later comparing blood samples collected before and after exposures.
Diesel exhaust induced DNA changes but filtered air did not, according to lead researcher Christopher Carlsten, a respirologist and associate professor in the division of respiratory medicine.
The study by the researchers at UBC and Vancouver Coastal Health is published in the journal Particle and Fibre Toxicology. It showed that just two hours of exposure to diesel exhaust fumes led to biological changes that meant some genes were switched on while others turned off. The air quality during the diesel fume exposures is said to be comparable to a Beijing highway or shipping ports in British Columbia.

So who exactly is Paul Calandra, anyway?
