3.The main pathological changes of PAH are vasoconstriction and arteriole organization afterward.而缺氧性肺血管收缩及小动脉机化是其主要病理变化。

4.Indeed, we recently observed impaired apoptotic regulation of endothelial cells in lung biopsy samples from patients with irreversible PAH.事实上，我们从不可逆肺高压患者的肺活检标本中观察到受损内皮细胞的凋亡调控。

5.The Commission adopted the first guidelines for reducing polycyclic aromatic hydrocarbons (PAH) intake through final food preparation.委员会通过了关于在食品最后制备过程中减少多环芳烃摄入的第一份准则。

6.The total amount of PAH given to each mouse over the three-week injection cycle was equivalent to 25 packs of cigarettes.在为期3周的注射周期中，每只接受注射的小鼠的PAH给药总量相当于25包香烟。

7.genetic operons, can be used to enhance the degradation of PAH compounds.遗传操纵子，可有效提升发病的降解化合物。

8.Genes that catalyze PAH degradation are believed to have adaptively evolved in nature by various genetic events.催化降解多环芳烃的基因被认为是自然界演化自适应各种遗传事件。

9.Toxic matagenic and carcinogenic PAH diol epoxides can be derived from PAHS, which are responsible for most cases of lung cancer.有毒的matagenic和致癌物质PAH二醇环氧化合物均来源于多环芳香烃（PAH），它是导致大多数肺癌的罪魁祸首。

10.The researchers developed models to calculate the associations between prenatal PAH exposure and IQ.研究人员开发了数种模型来计算出出生前多环芳烃得接触与智商之间的关系。
