Description (provided by applicant): The overall aim of this core is to evaluate mechanisms of oxidative injury, inflammation and repair in both the respiratory and cardiovascular systems caused by environmental and occupational agents. This aim has been a central focus for the core since the 1940?s when Rochester first began investigation into the pulmonary toxicology of airborne particulates. Focus today continues not only on airborne particulates, but also on oxidant gases, endotoxin, siloxanes, zinc oxide and ionizing radiation. Experimental approaches range from basic cellular and molecular methods to animal and clinical human studies. The core studies the impact of inhaled agents in asthma, COPD, fibrosis and lung cancer. Factors that modulate the toxicological effects of inhaled agents, such as age and underlying disease, are also studied. A new approach that has evolved over the last 5 years is the focus on systemic effects of inhaled agents, in particular effects on the cardiovascular system. Nearly 50% of the 181 publications cited since the last renewal are joint authored by members of the core, speaking to the intense collaborative effort underway. The studies carried out by core members result in publications in strong, high-impact scientific journals (AJP Lung, AJRCCM, Environ Health Perspectives, J Immunol, Inhalation Toxicol). All members are now housed under one roof with the construction of a new research building, enhancing the collaborative effort.

描述（由申请人提供）：本核心的总体目标是评估由环境和职业因素引起的呼吸系统和心血管系统的氧化损伤，炎症和修复机制。自20世纪40年代以来，这一目标一直是核心的核心焦点。那时罗切斯特刚开始研究空气中微粒的肺部毒理学。今天的重点不仅是空气中的微粒，还包括氧化气体、内毒素、硅氧烷、氧化锌和电离辐射。实验方法包括从基本的细胞和分子方法到动物和临床人体研究。核心研究吸入剂对哮喘、慢性阻塞性肺病、纤维化和肺癌的影响。还研究了调节吸入剂毒性作用的因素，如年龄和潜在疾病。在过去5年中发展起来的一种新方法是关注吸入剂的全身效应，特别是对心血管系统的影响。自上次更新以来，被引用的181份出版物中有近50%是由核心成员联合撰写的，说明正在进行的密切合作努力。由核心成员进行的研究结果发表在强大的，高影响力的科学期刊上（AJP Lung， AJRCCM, environmental Health Perspectives, J Immunol, respiratory Toxicol）。所有成员现在都住在一个屋檐下，并建造了一个新的研究大楼，加强了合作努力。
