Interactions between recognition molecules on the surface of neuronal growth cones and guidance cues present in the local cellular environment are thought to account for the growth of neurites in the highly stereospecific manner that contributes to correct target cell innervation. In vitro assays have been used to identify candidate molecular components of(More)
Upper limb pain occurred in close temporal association with attacks of migraine, cluster headache and cluster-migraine in 22 cases. Seven had also lower limb pain. Limb pain was usually ipsilateral to the headache but could alternate sides and behaved like other accepted migraine accompaniments. It was always ipsilateral to the associated(More)
Upper and lower limb pain associated to attacks of migraine or cluster headache has been mentioned by many authors since the early descriptions of Liveing, Gowers and Jeliffe. The symptom was also described by Sluder as part of the syndrome of "sphenopalatine ganglion neuralgia." Several authors in the 1920's and 1930's including Cushing and Harris reported(More)
The retrograde transport of fluorochromes from muscle was used to label embryonic rat motoneurones in vivo. The fluorescent motoneurones were subsequently detected in cultures of dissociated spinal cord neurones using an image-intensification video camera, the images from which allowed identification of the motoneurones under phase-contrast microscopy. Such(More)
BACKGROUND Neurological complications are frequently observed in HIV-1 patients. Lumbar puncture (LP) and LSF analysis are two key diagnostic procedures. AIM To describe the etiology meningeal syndromes in a hospital series of HIV patients. RESULTS In this study, we present the different meningeal complications from 198 HIV-1 patients referred, for the(More)
Chronic inflammatory demyelinating polyneuropathy is a heterogeneous disease characterized by symmetrical motor and sensitive alterations, absence of tendon reflexes and increased cerebrospinal fluid protein levels. We report 6 patients with the disease, (three males) aged 41 to 70 years old. Four had the classical presentation and two had an asymmetrical(More)
