    The CYP1A1 gene encodes microsomal cytochrome P4501A1 that catalyzes the metabolism of many xenobiotics, including the oxygenation of polycyclic aromatic hydrocarbons (PAH). Induction of CYP1A1 enhances the metabolism of PAHs, and therefore, represents an adaptive response to chemical exposure in mammalian cells. Mechanistic studies reveal an AhR/D ...

    To the Editor: The case report by Srinivasan et al. (July 26 issue) makes one wonder when glanders was first suspected as this patient's illness. The patient's work history included potential exposure to Burkholderia mallei without personal protective equipment (gloves). Yet the patient was treated twice with agents not indicated for B. mallei infe ...

  • Severity index for use in statebased surveillance of acute pesticiderelated illness and injury
    Severity index for use in state-based surveillance of acute pesticide-related illness and injury.
    National Institute for Occupational Safety and Health
    2001/11/27 | National Institute for Occupational Safety and Health (NIOSH)
    The purpose of the severity index is to provide simple, standardized criteria for assigning severity to cases of acute pesticide-related illness and inj ury. It is important to assign a severity category to each case of acute pesticide-related illness and injury. An understanding of illness severity will be useful for evaluating the morbidity of ac ...

    Body temperature profiles observed during methamphetamine (METH) exposure are known to affect dopamine and tyrosine hydroxylase (TH) levels in the striatum of mice; hyperthermia potentiates depletion while hypothermia is protective against depletions. In the current study, the doses of METH were sufficiently great that significant dopamine and TH d ...

    2001/11/15 | National Institute for Occupational Safety and Health (NIOSH)
    Nickel compounds induce cell transformation in cell culture models and tumor formation in experimental animals. However, the molecular mechanisms by which nickel compounds induce tumors are not yet well understood. The present study found that exposure of cells to either Ni(3)S(2) or NiCl(2) could result in specific transactivation of nuclear facto ...

    In situ pH control may be a viable method for enhancing remediation of contaminated groundwater and sediment. pH can limit certain anaerobic subsurface microbes employed in bioremediation efforts. Investigations into pH control must begin with an evaluation of the effect of pH on microbes actively metabolizing contaminants in sediment from a potent ...

    A 73-year old farmer died on May 2, 2001 from injuries received when he was crushed within a hay baler. OKFACE investigators concluded that to prevent similar occurrences, employers should: 1. Maintain tractors and similar farm equipment in safe operating condition and follow manufacturer recommendations when using, maintaining, and servicing power ...

    What dental technicians need to know about silicosis
    New Jersey. Department of Health. Public Health Services Branch. Consumer, Environmental and Occupational Health Service. Environmental & Occupational Health Surveillance Program
    2001/11/01 | National Institute for Occupational Safety and Health (NIOSH)
    Can Silicosis Be Cured? No. There is no known medical treatment to reverse silicosis or stop its progress. This disease can only be prevented by controlling exposure to silica dust. Workers who have been exposed to silica should stop smoking to reduce their risk of developing lung cancer. Are There Other Potential Health Hazards Associated With Wor ...

    2001/11/01 | National Institute for Occupational Safety and Health (NIOSH)
    A significant number of injuries in the workplace is attributed to slips and falls. Biomechanical responses to actual slip events determine whether the outcome of a slip will be recovery or a fall. The goal of this study was to examine lower extremity joint moments and postural adjustments for experimental evidence of corrective strategies evoked d ...

    In this study, we examined the effect of stilbene estrogen, diethylstilbestrol (DES), on the DNA repair capacity of mouse Leydig cells using the host cell reactivation assay. Cells transfected with UV-damaged plasmids, undamaged plasmids, or no plasmids (sham treatment) were grown in serum, serum-free, or DES plus serum-free medium. The serum-grown ...

    Self-reported work histories are an essential tool for estimating exposure in many occupational epidemiologic studies. However, the transience of some occupations such as farm work can hamper recall, resulting in inaccurate reporting. To address this problem, we have developed an icon/calendar-based questionnaire. This study compares work histories ...

    2001/11/01 | Fatality Assessment and Control Evaluation Reports (FACE)
    An uprooted tree struck and killed a 34-year-old logging supervisor and a 33-year-old logger (the victims). The victims were part of a six-man crew using a crane to move cut timber from a slope to a road. The mobile crane, known as a "yarder," was located on the road above the slope. It was anchored by a single guyline to an uncut tree on the hills ...

    Ototoxicity following combined exposure to noise and carbon monoxide (CO) is known to result in more severe permanent threshold shifts than exposure to noise alone. We have previously demonstrated that such potentiation of noise-induced auditory impairment by CO can be prevented by the administration of a nitrone spin-trapping agent. Although such ...

    2001/11/01 | Mining Publications
    The two major lung diseases of miners are "blacklung" and silicosis. Blacklung, or pneumoconiosis, was first recognized as a disease of British coal miners in the 16005. However, investigations into the cause of blacklung disease did not begin until the 1900s. The causative agent of pneumoconiosis in coal miners was thought to be silica until studi ...
