In this study, the anti-inflammatory properties of formoterol and ipratropium bromide, alone or in combination, were investigated in a rat model of acute pulmonary inflammation induced by cadmium inhalation. Airway resistance and inflammatory responses, including matrix metalloproteinease-2 (MMP-2) and matrix metalloproteinease-9 (MMP-9) activities, were evaluated. Compared to values obtained in rats exposed to cadmium, pretreatment by bronchodilators administered alone significantly prevented the cadmium-induced increase of airway resistance. Formoterol elicited a significant decrease in total cell number, neutrophil and macrophage counts in bronchoalveolar lavage fluid, whereas ipratropium bromide reduced neutrophil numbers. The two compounds administered alone significantly attenuated the lung lesions associated with parenchyma inflammatory cell influx and congestion observed in the cadmium group. The increased MMP-9 activity was significantly attenuated. Although only formoterol induced a decrease protein concentration in bronchoalveolar lavage fluid, both compounds inhibited the pulmonary edema by reducing wet-to-dry weight ratio which returned to values similar to those recorded in the sham group. All the effects of formoterol on the cadmium-induced inflammatory responses were reversed by propranolol. Similar anti-inflammatory effects were obtained in rats pretreated with ilomastat which showed a significant reduction on inflammatory cell infiltration and MMP-9 activity in bronchoalveolar lavage fluid. Neither synergistic nor additive effects were obtained when the two bronchodilators were administered in combination. In conclusion, formoterol and ipratropium bromide partially protect the lungs against the inflammation by reducing neutrophilic infiltration. This protective effect is associated with reduced MMP-9 activity known to play an important pro-inflammatory role in acute inflammatory process. [less ▲]

A comprehensive investigation of the coupling between mobile devices and communication/control cables in several environments is described here. Both experimental and numerical results are shown and compared using a number of different methods in different laboratories. Results indicate a good level of agreement between the different approaches thus giving confidence that predictive studies based on simulation can give a good quantitative assessment of coupling. Moreover, the studies show that varying the configuration of the coupled systems does not significantly affects the maximum coupling thus making it possible to obtain a reasonable worst case estimate of coupling from a small number of generic studies.

The auroral emissions that resulted from the series of solar particle events and magnetic storms during 14-24 April 2002 provide an excellent data set for the cross-comparison of the IMAGE/FUV and TIMED/GUVI auroral imagers. The IMAGE/FUV instrument comprises the SI spectral imager (121.8 nm and 135.6 nm) and the WIC imaging photometer (LBH) and observes the entire Earth from high Earth orbit. The TIMED/GUVI spectral imager (121.6 nm, 130.4 nm, 135.6 nm, LBH short, and LBH long) scans a nadir-to-limb swath from low Earth orbit. Although there is a large difference in spatial resolution, preliminary comparison of simultaneously-observed diffuse auroral emissions indicates fairly good agreement between the calibrated brightnesses determined for common spectral features. We will present a detailed simulation of one or more of the April 2002 events as seen by each imager to determine if a single description of the auroral precipitation can self-consistently account for the proton- and electron-generated FUV emissions observed from the two spacecraft.
