    Benzene is a highly volatile aromatic hydrocarbon solvent which is present in most petroleum distillates such as Stoddard solvent and mineral spirits. Recent advances in the purification process for these solvents has reduced the benzene content significantly, but it is still present in products such as WD-40 and Liquid Wrench as well as many solvents used in the printing industry and elsewhere.

    Low speed motor vehicle collisions are a common occurrence. The use of cellular phones, text messaging, and e-mailing while driving has only increased the frequency of low speed motor vehicle collisions. A motor vehicle collision where there is only minor damage to the vehicles may result in personal injury claims for substantial sums.

    10/11/2012 · Toxicogenomics
    In toxic tort litigation, a person is often claiming to have developed cancer or some other serious disease due to having been exposed to a particular substance. Determining if the exposure to the substance was the cause of the disease is often a central focus of the litigation.

    9/26/2012 · Medical
    It is a common error that an attorney retains the wrong type of expert to testify in a lawsuit. This error is particularly common when the expert is a medical specialist. It is widely believed that a medical doctor who specializes in a particular organ system is qualified to formulate opinions and testify as to all issues concerning that organ system.

    Reproduction, the most important process in nature, is the result of a superbly coordinated series of events. The modern era has seen the introduction of chemical and physical agents that can disrupt these events and impair normal reproduction. This book satisfies the clinician's need to understand toxicology and its effect on human reproduction by explaining the lingo of the bench researcher and teaching the clinician how to use basic research in practice.
    By Anthony R. Scialli, MD
    One of the most popular areas in toxicology is environmental toxicology and its effects on human fertility. Designed as a clinical reference, this book focuses on both the mechanisms of reproductive failure (male and female) and the clinical techniques for assessing and monitoring the effects of various toxicants on the reproductive process. Section I provides a basic overview of the toxicologic effects of various agents on male and female reproductive physiology and the process of conception. Section II builds on this background and covers the mechanisms of toxicant action, describing the ways in which normal reproduction may become deranged.
