These carcinogen precursors are inhaled through automobiles exhaust during the morning commute, are present in a drag of cigarette smoke, and are part of any barbequed meal. http://medicalxpress.com/news/2012-11-supercomputer-simulations-carcinogens-evade.html Cancer Fri, 02 Nov 2012 12:13:29 EST news271077199 Pulmonary hypertension combination therapy may lead to greater disease burden Patients with pulmonary arterial hypertension (PAH) receiving combination therapy with intravenous (IV) PGI2 may suffer from greater disease burden compared with those receiving monotherapy or combination therapy, excluding IV PGI2. http://medicalxpress.com/news/2012-10-pulmonary-hypertension-combination-therapy-greater.html Diseases, Conditions, Syndromes Mon, 22 Oct 2012 03:26:50 EST news270095200 Breakthrough could help sufferers of fatal lung disease Pioneering research conducted by the University of Sheffield is paving the way for new treatments which could benefit patients suffering from the fatal lung disease pulmonary arterial hypertension (PAH). http://medicalxpress.com/news/2012-10-breakthrough-fatal-lung-disease.html Medical research Mon, 15 Oct 2012 05:21:07 EST news269497258 DNA damage in roofers due to PAH exposure -- possible cancer link Roofers and road construction workers who use hot asphalt are exposed to high levels of polycyclic aromatic hydrocarbons (PAHs). A University of Colorado Cancer Center study published this week in the British Medical Journal Open shows that roofers have higher PAH blood-levels after a shift than before and that these high levels of PAHs are linked with increased rates of DNA damage, and potentially with higher cancer risk. http://medicalxpress.com/news/2012-07-dna-roofers-due-pah-exposure.html Cancer Thu, 26 Jul 2012 11:10:01 EST news262518835 Prenatal exposure to air pollution linked to childhood obesity Overall, 17% of children in the United States are obese, and in inner-city neighborhoods, the prevalence is as high as 25%.
