OBJECTIVE The apolipoprotein E (APOE) polymorphism is known to impact on various neurologic disorders and has differential effects on the immune system and on CNS repair. Previous findings concerning a possible modulation of the clinical course of MS have been inconsistent, however. METHODS In a cross-sectional study, the authors investigated 374 patients(More)
Acute, parainfectious, disseminated encephalo-myelitis (ADEM) is usually treated with corticosteroids. Intravenous immunoglobulins have not been applied to patients with ADEM. This article describes a 22-year old woman who developed progressive paraparesis, ascending sensory dysfunction, and urinary incontinence one week after tonsillitis. Guillain-Barré(More)
White clover/perennial ryegrass mixtures (Trifolium repens L., Lolium perenne L.) are potential understory candidates for temperate agroforestry systems. A 2-year artificial shade experiment was conducted to determine the effects of shade on herbage production and quality and on changes in sward composition under field conditions. Wooden frames covered by(More)
In the temperate zone, alley cropping is promoted as a climate change-resilient agroforestry practice for the provision of biogenic energy carriers. However, little information is available on the potential of such cropping systems as feedstock for biofuel production. In a field trial in Central Europe, the triennial performance of alley cropping systems(More)
Alley cropping multi-rows of shrub willow hybrids and grassland is a promising temperate agroforestry practice for an environmentally sound provision of bioenergy feedstock. The effect of willows, aged 2–3 years, on two grassland mixtures (clover-grass, diversity oriented mixture) was determined at three positions along the tree-crop interface at a study(More)
Fractures of the cervical spine in ankylosing spondylitis are rare. The rate of neurological complications is increased compared to fractures of the normal spine. Concerning its mechanical characteristics the ankylosing spine is similar to a long bone. Because of the deformity and the stiffness of the spine conventional orthoses do not provide enough(More)
