    Frazer DG ;
    Goldsmith WT
    2000/04/30 | National Institute for Occupational Safety and Health (NIOSH)
    In many experiments involving both data and video collection it may be desired to synchronize the collected analog/digital data with the recorded video. This paper demonstrates two LabVIEW Virtual Instruments (VI), which use a single A/D channel to collect and decode SMPTE (Society of Motion Picture Television Engineers) time codes. This paper will ...

  • Superinduction of CYP1A1 Gene Expression Regulation of 23 78TetrachlorodibenzoPDioxinInduced Degradation of Ah Receptor by Cycloheximide
    Superinduction of CYP1A1 Gene Expression. Regulation of 2,3, 7,8-Tetrachlorodibenzo-P-Dioxin-Induced Degradation of Ah Receptor by Cycloheximide
    Antonini JM ;
    Baldwin KT
    2000/04/26 | National Institute for Occupational Safety and Health (NIOSH)
    Cycloheximide superinduces the transcription of CYP1A1 in the presence of an agonist for the Ah receptor (AhR). To investigate the molecular target for "superinduction," we analyzed the agonist-induced degradation of AhR. Whereas 2,3,7, 8-tetrachlorodibenzo-p-dioxin (TCDD), a potent agonist of AhR, induces a rapid reduction of the AhR protein, cycl ...

    We used myeloperoxidase-containing HL-60 cells to generate phenoxyl radicals from nontoxic concentrations of a vitamin E homologue, 2,2, 5,7,8-pentamethyl-6-hydroxychromane (PMC) to test whether these radicals can induce oxidative stress in a physiological intracellular environment. In the presence of H(2)O(2), we were able to generate steady-state ...

    2000/04/20 | National Institute for Occupational Safety and Health (NIOSH)
    Exposure to NRL allergens plays a key role in inducing NRL allergy. We therefore compared the relative abilities of air and dust sampling to detect NRL allergen contamination in a medical facility. High volume area air samples and vacuumed bulk surface dust samples were collected onto Teflon filters in several hospital and clinic settings. Control ...

    TMA is known to produce occupational asthma that associated with its ability to acylate proteins and to induce production of TMA-specific IgE. Though the respiratory tract is considered to be a major exposure route leading to sensitization, the potential role of dermal exposure is not known. Animal studies have shown that topical application of TMA ...

    Delivery of modified Krebs-Henseleit solution (MKHS) of raised osmolarity (added NaCl or KCl) to the lumen of methacholine (MCh)-contracted IPT results in a relaxation response of the airway smooth muscle that is mediated by epithelium-derived relaxing factor (EpDRF). We compared the effects of luminally-applied solutions containing organic osmolyt ...

  • Can Gas Trapping at Low Lung Volumes Reduce Total Lung Capacity
    Can Gas Trapping at Low Lung Volumes Reduce Total Lung Capacity?

    Friend KA
    2000/04/14 | National Institute for Occupational Safety and Health (NIOSH)
    In the past we have examined many characteristics of the mechanism responsible for gas trapping in excised lungs [1,2]. Even though there is evidence that gas is trapped during lung inflation [2] and remains trapped at maximum lung volume [3], the effects of gas trapping on the mechanical properties of the lung during expansion are not well underst ...

    It has previously been shown that tidal volume and minute ventilation decrease in rats exposed to ozone [1]. In this study, pre and post exposure thoracic breathing patterns were measured in Sprague-Dawley rats (n=9) exposed to 2 ppm O3 for three hours. The previous results of O3 exposure in rats were confirmed. In addition to confirming the result ...

    Physicians have used the presence and characteristics of cough as a diagnostic tool for many years. Researchers have shown that cough sound analysis can assist in the diagnosis of respiratory disease [1]. Important considerations such as cough intensity and duration may affect the sounds produced by the lungs. To reliably classify cough sounds, the ...
