Proliferative activity and motoneurone recruitment persist at the spinal cord central canal during larval and some postlarval stages in the rainbow trout (Oncorhynchus mykiss)

Autor: A Alunni, F Pierucci, M Aita, V Margotta, R De Vita, L Alfei

Publikováno v: European Journal of Histochemistry, Vol 45, Iss 2 (2009)

We previously found a linear relationship between the cross sectional myotomal area and the motoneurone number in the growing trout during postlarval stages. These neurones increased in number until a fish length of 150 mm, which prompted us to exami

PCNA positivity in the telencephalic matrix areas in the adult of a newt, Triturus carnifex

Autor: V, Margotta, A, Morelli, L, Alfei

Publikováno v: Journal fur Hirnforschung. 39(4)

The Proliferating Cell Nuclear Antigen (PCNA) is an auxiliary protein of the DNA polymerase delta, belonging to the cyclin family, which attains appreciable levels only in those phases of the cell cycle in which DNA synthesis occurs. Using an immunoc

PCNA positivity in the telencephalic matrix areas in the adult of a lizard, Podarcis sicula

Autor: V, Margotta, A, Morelli, L, Alfei

Publikováno v: Journal fur Hirnforschung. 39(3)

In the present paper a reappraisal is made of the persistence and size of telencephalic matrix areas in normal adult specimens of a lizard, Podarcis sicula, using a recent in situ marker of cells in the S phase, the Proliferating Cell Nuclear Antigen

Hyaluronate receptor CD44 is expressed by astrocytes in the adult chicken and in astrocyte cell precursors in early development of the chick spinal cord

Autor: L, Alfei, M, Aita, B, Caronti, R, De Vita, V, Margotta, L, Medolago Albani, A M, Valente

Publikováno v: European journal of histochemistry : EJH. 43(1)

The role of the hyaluronate receptor, CD44, is well known in adult mammal astrocytes where it modulates neuron-glia interactions. However, no data exist regarding its expression in other vertebrates during their development. In order to detect the ex

Effects of cocaine treatment on the nervous system of planaria (Dugesia gonocephala s. l.). Histochemical and ultrastructural observations

Autor: V, Margotta, B, Caronti, G, Meco, A, Merante, S, Ruggieri, G, Venturini, G, Palladini

Publikováno v: European journal of histochemistry : EJH. 41(3)

Acute high dose treatment with cocaine in planaria has been shown to produce hyperkinesia followed by immobilization, thus suggesting progressive neuronal dopamine (DA) depletion. On the contrary, treatment with low doses of cocaine inhibits motor ac

Medullary and gangliar regeneration after unilateral removal of a segment of spinal cord of the trunk and corresponding ganglion in adult newts

Autor: S, Filoni, V, Margotta, F A, Madía, S, Bernardini, S M, Cannata

Publikováno v: Journal fur Hirnforschung. 36(4)

Regeneration of the spinal cord, segmental nerves and sensory ganglia takes place after tail amputation in the newt. Many histological and immunocytochemical observations provide evidence that the ependymal tube is the source not only of new neurons

Persistence of a high degree of structural organization of the telencephalon in brain homotransplants in adult Triturus carnifex (Urodele Amphibians)

Autor: V, Margotta, S, Filoni, P, Del Vecchio

Publikováno v: Journal fur Hirnforschung. 34(2)

Brains of adult Urodele Amphibians (Triturus carnifex Laur.) were homoplastically transplanted in conditions of complete morpho-functional isolation and fixed 100 and 365 days after the operation. Results show that in the post-telencephalic regions s

Degenerative and regenerative phenomena in brain heterotopic homoplastic transplants of adult Triturus carnifex (Urodele Amphibians)

Autor: V, Margotta, S, Filoni, P, Del Vecchio

Publikováno v: Journal fur Hirnforschung. 33(1)

The brains of adult Urodele Amphibians (Triturus carnifex Laur.) were homoplastically transplanted in conditions of complete morpho-functional isolation. Despite the heterogeneous nature of the histological aspects observed, the results point to the

Phylogenetic evolution of intermediate filament associated proteins in ependymal cells of several adult poikilotherm vertebrates

Autor: G M, Lauro, R, Fonti, V, Margotta

Publikováno v: Journal fur Hirnforschung. 32(2)

The cytoskeletal proteins are phylogenetically well preserved in Vertebrates. However, unlike the case of Mammals, comparatively little is known about the immunocytochemical characterization of the intermediate filaments (IF) of the ependymal epithel

Transient expression of glial-fibrillary acidic protein (GFAP) in the ependyma of the regenerating spinal cord in adult newts

Autor: V, Margotta, R, Fonti, G, Palladini, S, Filoni, G M, Lauro

Publikováno v: Journal fur Hirnforschung. 32(4)

In the homeotherms the presence of glial-fibrillary acidic protein (GFAP) and that of neurofilaments (NF) are used as specific molecular markers associated with intermediate filaments (IF) of the glial and neuronal elements respectively. On this basi
