    Effects of chlorpromazine and promazine on the visual aftereffects of tilt and movement (1983)
    Springer
    Psychopharmacology 79 (1983), S. 49-57 
    Details
    ISSN: 1432-2072
    Keywords: Phenothiazines ; Schizophrenia ; Visual aftereffects ; Normal volunteers

    Topics: Medicine
    Notes: Abstract The effects of chlorpromazine (CPZ) and promazine on the visual aftereffects of tilt and motion were measured. CPZ markedly reduced the strength of both aftereffects, while promazine produced a smaller and not always significant reduction. Control experiments suggested that the effects were produced in the central visual system rather than by several possible peripheral artefacts or by drowsiness. The effects are disscussed with reference to the pharmacological activity of the drugs and their influence on the strength of inhibition in the visual cortex, both in normal subjects and in schizophrenic illness.

    Effects of haloperidol and nomifensine on the visual aftereffects of tilt and movement (1986)
    Springer
    Psychopharmacology 89 (1986), S. 177-182 
    Details
    ISSN: 1432-2072
    Keywords: Adaptation ; Human visual system ; Dopamine

    Topics: Medicine
    Notes: Abstract An antipsychotic and two antidepressant drugs were studied for their effects on the visual aftereffects of tilt and movement in normal volunteers. Compared with placebo, haloperidol reduced the aftereffects. The antidepressant nomifensine enhanced the tilt but not the movement aftereffect, while maprotiline (another antidepressant) had no significant effect on either aftereffect. Control experiments showed that these changes were unlikely to have resulted from drug induced alterations in scanning eye movements during adaptation. The results are discussed with reference to possible dopaminergic influences on the visual system, and to some of the symptoms of schizophrenia.

    Modification of visual orientation illusions by drugs which influence dopamine and GABA neurones: Differential effects on simultaneous and successive illusions (1986)

    Topics: Medicine
    Notes: Abstract The effects of haloperidol, nomifensine and lorazepam on the visual tilt illusion were studied in normal volunteers. Haloperidol and nomifensine produced no significant changes in the illusion, although in previous work they had been found to reduce and and enhance, respectively, a closely related illusion, the tilt aftereffect. By contrast, lorazepam produced a dose-related increment in the size of the tilt illusion, but had no effect on the tilt aftereffect. The results are discussed in relation to proposed mechanisms which may underlie the two kinds of illusion. The differential effects of individual drugs on the two illusions may reflect their differing actions on two processes: lateral inhibition and adaptation in visual channels.

    Effects of lorazepam on human contrast sensitivity (1995)

    Notes: Abstract The anxiolytic lorazepam was studied for its effects on contrast sensitivity to gratings flickering in counterphase in normal volunteers. The drug significantly reduced contrast sensitivity at low spatial frequencies in a dose-related manner. The results are discussed with reference to possible GABA-mediated processes in the retina and lateral geniculate nucleus.

    Incidental findings on trauma ultrasonography (2000)
    Springer
    Emergency radiology 7 (2000), S. 19-24 
    Details
    ISSN: 1438-1435
    Keywords: Key words Ultrasonography, emergency – Ultrasonography, abdominal – Trauma, blunt abdominal
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract Purpose: To determine the prevalence of incidental findings detected on the focused abdominal sonogram for trauma. Methods: From November 1996 to February 1998, 1914 radiologist-assisted trauma ultrasound examinations were performed. Incidental findings were tabulated by retrospective review of the trauma radiology daily logbooks. Results: Incidental nontraumatic findings were detected in 160 (8.36 %) of the acutely injured patients. Most findings were benign, including echogenic liver, renal cysts, and cholelithiasis. However, significant pathology was detected in several patients, including renal masses, hepatic metastases, and gynecologic disease. Conclusion: The radiologist-assisted trauma ultrasound examination can provide valuable diagnostic information beyond the detection of free fluid. This may have important implications, as nonradiologists are increasingly involved in the practice of trauma ultrasonography. Even in the setting of trauma, significant occult pathology can be detected on a targeted ultrasound examination.

    The thermal conductivity of Kevlar fibre-reinforced composites (1982)
    Springer
    Journal of materials science 17 (1982), S. 2925-2931 
    Details
    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract The thermal conductivities of a series of blocks consisting of Shell DX210/BF3400 resin reinforced with Kevlar 49 fibre are reported in the approximate temperature range 180–270 K. The results are used to calculate the thermal conductivities of the fibres in directions parallel and perpendicular to their length. Varying the angle between the principal fibre directions of bidirectional laminates produced in-plane results that varied in a manner which was quantitatively consistent with expectation. The out-of-plane results proved to be independent of fibre orientation, as expected. In-plane and out-of-plane results for a Kevlar 49 fabric reinforced laminate proved to be essentially similar to results for a laminate reinforced with unwoven fibres of the same type, arranged in a 90° cross-plied disposition at the same fibre volume density.

    Comparison of immune-mediated models of acute and chronic otitis media (1990)

    Notes: Summary The distribution of immunoglobulin-bearing cells and the pattern of histopathological changes in the middle ear (ME) mucosa, round window membrane (RWM), and inner ear were compared during acute and chronic immune-mediated otitis media with effusion (OME) in the guinea pig as an animal model. In both acute and chronic immune responses (IRs), mucosal hyperplasia, edema, neovascularization, and cellular infiltration were observed. IgG+ cells were predominant in both the acute and chronic IRs. The number of IgA+ cells, however, increased in the mucosa and RWM during chronic IRs. Only the chronic IR resulted in gland formation within the ME and inflammation within the cochlea. These results indicate that the chronic IR was more similar to reports of clinical OME than the acute IR, The cochlear inflammation associated with chronic OME can lead to sensorineural hearing loss, as reported in clinical studies.
