    2000/03/15 | National Institute for Occupational Safety and Health (NIOSH)
    We have shown previously that the lung surfactant inhibits LPS-stimulated nitric oxide (NO) production in alveolar macrophages (Miles et al., Am.J.Physiol. 276:Ll86, 1999). But lung surfactant had no effect on NO production in two macrophage cell lines RAW 264.7 and J-774. Stimulation of primary macrophages and cell lines by LPS has been shown to a ...

    2000/03/14 | Fatality Assessment and Control Evaluation Reports (FACE)
    A 49-year-old male forklift operator (decedent) died when the canopy of a straddle fork that overturned crushed him. A straddle fork is a forklift-like machine that has forks for lifting fruit bins up to a hydraulic stacking system on the front of the machine and straps that come over the top to secure the bins. The decedent was moving bins of lemo ...

    A large number of workers are potentially exposed to cadmium during mining and processing. Therefore, there is a concern regarding the potential carcinogenic hazards of cadmium to exposed workers. Studies have been performed to determine if cadmium chloride (CdCl(2)) can induce morphological cell transformation, DNA from CdCl(2)-induced transformed ...

    2000/03/10 | Fatality Assessment and Control Evaluation Reports (FACE)
    An 24-year-old male farmer (the victim) died after becoming entangled in the unguarded rotating driveline shaft of a manure spreader. The spreader was connected to a tractor equipped with a power take-off (PTO), which powered the spreader driveline. The victim was working alone in the barnyard, replacing a bolt on the shaft. He apparently had compl ...

    In-Depth Survey Report: Evaluation of Control Technology for Perchloroethylene in Dry Cleaning Shops at Ten Ten Cleaners, San Francisco, California
    Burroughs, G. Edward
    2000/03/06 | Engineering and Physical Hazards Survey Reports
    NIOSH evaluated eight dry cleaning shops to determine the extent of exposure and the technological feasibility of controlling worker exposure to perchloroethylene (Perc). In this study, dry cleaning plants were selected and data taken to characterize worker exposure levels and control technology for "fourth generation" closed-loop, dry-to-dry machi ...

    We compared the effects of treatment with high doses of fluoxetine, sibutramine, sertraline, and dexfenfluramine for 4 days on brain serotonergic nerve terminals in rats. Methylenedioxymethamphetamine (MDMA) and 5,7-dihydroxytryptamine (5,7-DHT) were used as positive controls because both compounds deplete brain serotonin. Food intake and body weig ...

    A 42-year-old male fitter/welder (decedent) died when he was crushed between a stationary pressure vessel (a type of unfired, cylindrical tank) and a pressure vessel that had tipped up. The decedent was on top of the pressure vessel that tipped while he was welding a seam on a manway (personnel hatch). The pressure vessel he was on was lying length ...

    2000/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    We studied the mechanism(s) through which oxidative stress participates in apoptotic signaling in keratinocytes. We exposed normal human keratinocytes (NHEKs)to cumene hydroperoxide (Cu-OOH, 50-200 microM) for 1 h and found significant and dose-dependent depletion of antioxidant reserves, oxidation of GSH and protein sulfhydryls. We metabolically l ...

    BACKGROUND: While many previous reports describe injuries to adolescents in the workplace, few focus on toxic substance exposures among such injuries. Yet low-skill, entry-level jobs pose a particular hazard of toxic exposure owing to the frequent use of cleaning agents, solvents, and/or other chemicals in carrying out assigned tasks. OBJECTIVE: To ...

    In Part 1 of this series, the authors discussed a recent study that evaluated dust levels at two Portland cement operations to determine how measured dust levels relate to a dust standard change being proposed by the Mine Safety and Health Administration (MSHA). These two operations differed in that one used the dry- and the other the wet-processin ...

    Monocyte chemoattractant protein (MCP)-1 has recently been reported to be up-regulated in many models of neuronal damage including infection, axotomy, alheimer's (mouse model), excitotoxicity, and traumatic brain injury. We investigated this protein and its gene expression using a well characterized model of hippocampal neuronal damage (trimethyl t ...

    The timing of a stressful event with respect to antigen exposure affects the development of the immune response. We have demonstrated that restraint applied prior to sensitization alters the ear swelling response and the pattern of cytokine production differently than restraint applied prior to challenge. We hypothesized that restraint would also m ...

    Interactions between chemicals in a mixture and interactions of mixture components with the skin, can significantly alter the rate and extent of percutaneous absorption, as well as the cutaneous diposition of a xenobiotic. The predictive ability of dermal absorption models, and consequently, the dermal risk assessment process would be greatly impro ...
