    Notes: Abstract Stereognosis is the ability to recognise and discriminate forms. Oral stereognostic ability has been studied in different reports. The experimental design of the test is of primary importance as both the method used and the material applied may influence the results dramatically. The form, size and surface characteristics of the test piece, the presentation order, subject-related factors and the method of scoring all have their effect on the results. With regard to subject-related factors, ageing has a negative influence on stereognostic ability; gender is considered of no importance. Another influencing factor is dental status. A healthy natural dentition offers a very good oral stereognostic ability. Edentulous subjects usually show a decreased oral stereognostic ability, depending on the rehabilitation form. A number of questions have been addressed, especially with regard to the perception itself. Receptors mainly involved in oral stereognostic ability are located in various oral structures and form perception results from an association of more than one group of receptors. The following review tries to deal with these questions and attempts to provide clear guidelines for further research on oral stereognosis.

    Effects of b-adrenoceptor-blockade on stress-induced adrenocorticotrophin release in humans (1998)
    Springer
    European journal of applied physiology 77 (1998), S. 523-526 
    Details
    ISSN: 1439-6327

    Notes: Abstract We investigated the mechanisms of stress-induced alterations in adrenocorticotrophin (ACTH) release. Tandem parachutists received either a placebo or the β-adrenoceptor antagonist propranolol prior to a first time parachute jump. Blood samples were drawn 4 h before, immediately after, and 1 h after the jump. Cortisol and catecholamine concentrations displayed a significant stress-induced increase in both groups. The ACTH plasma concentrations significantly increased in the placebo and the propranolol group, with significantly more pronounced changes in the propranolol-treated subjects compared to the placebo group. These data demonstrated a stress-induced increase of ACTH plasma concentrations in humans that was enhanced by β-blockade.

    Biomechanical analyses of some instrumentations for stabilisation of dorso-lumbar spinal injuries (1983)
    Springer
    Medical & biological engineering & computing 21 (1983), S. 494-502 
    Details
    ISSN: 1741-0444
    Keywords: Biomechanics ; Fixation device ; Spinal fracture

    Topics: Biology , Chemistry and Pharmacology , Medicine
    Notes: Abstract Quantitative biomechanical analyses of approaches for the reduction and fixation of lumbardorsal injury are presented in this paper, entailing (i) classification of the types of injuries, (ii) analysis of the critical functional levels of forces exerted on the injured spinal structures and the stabilisation devices and (iii) the basis for the various modalities of injury reduction stabilisation modes, and for the use of conventional posteriorly attached compression or distraction devices, as well as anteriorly placed vertebral stabilisation-fixation device.
