oThe orphan drug epoprostenol sodium for injection or prostacycline has been approved as a standard long-term treatment of individuals with severe PAH
Nemerow comprehensive index method is widely used in the evaluation of PAH
occurs when the pulmonary circulation pressure is higher than normal, a condition caused by diseases (such as heart or lung disease and lung artery disease), hereditary factors and a variety of pathogens.
The Profile of PAH
concentrations in selected cities showed that the rural areas were subjugated by pyrogenic release of PAHs
, while the road traffic is the major contributor of PAH
increase in urban areas of Pakistan (Atif et al.
A 2011 report from the USGS outlined how PAH
compounds from sealcoat products can find their way into soils, storm waters, ponds, streams, lakes, and even house dust, as the compounds are tracked by foot, abraded by car tires, washed by rain and volatilize into the air.
is a disorder of the pulmonary arterioles characterised by endothelial proliferation, fibrointimal hyperplasia and in situ thrombosis with progressive obstructive vasculopathy, pulmonary hypertension and eventually right ventricular failure and death.
The current findings build on the Center's previous studies linking prenatal PAH
exposure with behavioral and cognitive issues, including associations with developmental delay at age 3, reduced IQ at age 5, and symptoms of anxiety/depression and attention problems at ages 6 and 7.
It found the toxicity levels of PAHs
are highest in winters.
Threereplicate recovery samples were prepared for each PAH
by spiking of appropriate amount of the PAH
standard into the 10 mL of D.
Alkane and PAH
depositional history, sources and fluxes in sediments from the Fraser River Basin and Strait of Georgia, Canada.
Many studies have shown that PAHs
such as Benz(a)anthracene, Benzo(b)fluoranthene, Dimethylbenzanthracene, Benzo(a)pyrene, Indeno(1,2,3-cd) pyrene and Dibenz(a,h)anthracene produce cancer in animals.
Our objective in this investigation was to characterize the long-term variability of PAH
concentrations in residential dust.
