At the core of the Robertson-Seymour theory of graph minors lies a powerful structure theorem which captures, for any fixed graph H, the common structural features of all the graphs not containing H as a minor. Robertson and Seymour prove several versions of this theorem, each stressing some particular aspects needed at a corresponding stage of the proof of(More)
The taste buds in the soft palate and the circumvallate papillae of the rat were investigated by the zinc iodide-osmium tetroxide technique. In addition, electron micrographs of taste buds stained with this method were presented for the first time. Differences in taste bud structures were found between the examined regions. The taste buds of the soft palate(More)
The nerve fiber distribution in the epidermis of the hairless rat skin was studied light microscopically by means of zinc iodide-osmium tetroxide staining. Two different morphological types of free nerve fiber endings could be detected: clusters of relatively thick nerve fibers stretched up through the spinous layer up to the granular layer sending off(More)
Methylene blue supravital staining of mammalian brain reveals typical staining patterns in different brain regions. Within the cerebellum of the mouse, the dye showed a peculiar affinity for the somata and the axons of Purkinje cells. Additionally, large polymorphic neurons characterized by long descending axons were detected within the granular layer and(More)
The recent paper 'Linear Connectivity Forces Large Complete Bipar-tite Minors' by Böhme et al. relies on a structure theorem for graphs with no H-minor. The sketch provided of how to deduce this theorem from the work of Robertson and Seymour appears to be incomplete. To fill this gap, we modify the main proof of that paper to work with a mere restatement of(More)
The murine cerebellum was investigated by light microscopy using an improved modification of Ehrlich's methylene blue supravital staining technique. The dye exhibited a special affinity for the perikarya as well as the axons of Purkinje cells. In addition, large fusiform or stellate nerve cells which were characterised by long descending axons were seen to(More)
Light microscopic observations employing intravital methylene blue staining and impregnation by the zinc iodide-osmium tetroxide technique are presented for intraepidermal nerve fibre endings of the intervibrissal fur in the mystacial pad of the rat snout. Both procedures revealed anatomical details of the intraepidermal nerve fibre plexus in epidermal(More)

The distribution pattern of methylene blue in the murine hippocampus after supravital dye application was studied light and electron microscopically. The characteristic, selective staining of nerve cell subpopulations occurred only in the presence of oxygen. Solitary or grouped polymorph neurons, i.e. non-pyramidal nerve cells, mainly located in the stratum(More)

Electron microscopic data on methylene blue staining of dendritic cells in the epithelia of the soft palate and skin of the mouse after supravital dye injection are presented. The ultra-structural details were compared with corresponding light microscopic findings. Methylene blue stained tissue was fixed by immersion in a paraformaldehyde-glutaraldehyde(More)

Light microscopic observations employing supravital methylene blue staining are presented for piloneural complexes of common fur hairs in the mystacial pad of the rat snout. The investigation revealed anatomical details of piloneural complexes belonging to follicles of both vellus and guard hairs. In the methylene blue stained preparations, different types(More)
