PAH

Abbreviation for p-aminohippuric acid.

pulmonary hypertension, primary, type 1

A rare disorder (OMIM:178600) characterised by plexiform lesions of proliferating endothelial cells in pulmonary arterioles, leading to elevated pulmonary arterial pressure, right ventricular failure and death. The disease can occur at any age from infancy onward, but has a mean age of onset at 36 years. Cases secondary to known aetiologies are the more common cause of pulmonary hypertension, and include those associated with appetite-suppressant drugs.

Molecular pathology
May be caused by defects of SMAD9, which encodes a receptor-regulated SMAD, transducing signals from TGF-beta family members.

Strong correlation of PAH in SLE patients with various predictors are presented in Table-I suggesting a future plan to work on it in detail.
The polycyclic aromatic hydrocarbons (PAHs) are a group of organic compounds containing two or more fused benzene rings which are generally generated from the incomplete combustion of petroleum, coal, fuel oil, garbage and other materials.
This study attempted to explore the genetic susceptibility of PAH development in SLE.
The pathogenesis of PAH is complex and still has not been completely elucidated.
A series of P[A.sub.6]-g-LCX-PAH fibers with different PAH grafting degrees were prepared by changing the ratio of PAH/LCX, pH value, initiator concentration, drying temperatures, and PAH concentration.
Polycyclic aromatic hydrocarbons (PAHs) are assembly of organic compounds which are abundantly present in the atmosphere of heavily populated areas which are having vehicular exhausts as well (Zheng, 2009).
Seven major PAH contaminants of concern (COCs) in sediment were identified in the original site risk assessment based on calculated cancer risk and hazard indexes, which were benz[a]anthracene, benzo[a]pyrene (BaP), benzo[b] fluoranthene, benzo[k]fluoranthene, chrysene, dibenz[a,h] anthracene, and indeno[1,2,3-c,d]pyrene.
To enhance PAH desorption from the trap (a quartz tube packed with glass wool), its high temperature has to be as high as possible.
The tests that are commonly performed to diagnose PAH and rule out other diseases are blood tests, pulmonary function tests, X-rays of the chest, electrocardiography (ECG), and the "6-minute walk test", which essentially measures how far an individual can walk in that time period.
Lab experiments have shown that HCAs and PAHs have the potential to cause changes to DNA, which means that they may increase the risk of cancer.
