    Notizen: Abstract The aetiology of adolescent idiopathic scoliosis (AIS) remains an enigma. In the literature there are two opinions: one believes a deviating growth pattern is responsible for the condition – patients with AIS tend to be growing faster/be taller – while the other opinion assumes that the growth pattern is normal, but its presence is necessary to allow the development of the scoliosis. We discuss the two stage hypothesis: the natural history of AIS involves an initial stage in which a small curve develops due to a small defect in the neuromuscular control system and a second stage during adolescent growth in which the scoliotic curve is exacerbated by biomechanical factors.

    Notizen: Abstract Although the structural changes occurring in the scoliotic spine have been reported as early as the 19th century, the descriptions and biomechanical explanations have not always been complete and consistent. In this study, three-dimensionally rendered CT images of two human skeletons with a scoliotic deformity and two patients with serious scoliosis were used to describe the intrinsic vertebral and rib deformities. The pattern of structural deformities was found to be consistent. Apart from the wedge deformation of the apical vertebrae, a rotation deformity was found in the transversal plane between the vertebral body and the posterior complex: the vertebral body was maximally rotated towards the convexity of the scoliotic curve, whereas the tip of the spinous process was pointed to posterior. The rib deformities at the convex side of the scoliotic curve showed an increased angulation of the rib at the posterior angle, whereas the rib curve on the concave side was flattened. The observed vertebral deformities suggest that these are caused by bone remodelling processes due to forces in the anterior spinal column, which drive the apical vertebral body out of the midline, whereas forces of the musculo-ligamentous structures at the posterior side of the spinal column attempt to minimize the deviations and rotations of the vertebrae. The demonstrated rib deformities suggest an adaptation to forces imposed by the scoliotic spine.

    Comparison of three methods for assessing varietal differences in resistance to common scab disease (Streptomyces scabies) of potato (1983)
    Springer
    Potato research 26 (1983), S. 175-178 
    Details
    ISSN: 1871-4528
    Schlagwort(e): breeding ; natural infection ; artificial inoculation

    Notizen: Summary Consistent varietal differences in scab severity were obtained when plants were grown in an open field or under a polythene tunnel in soil naturally infested withStreptomyces scabies, or in a glasshouse in pots filled with artificially inoculated sand. It was concluded that the glasshouse pot-inoculation technique would be the most suitable method to use in a breeding programme in which there are many clones to be tested, because a large number of plants can be grown in a small area under closely controled conditions.
