Morphology, distribution and number of unipolar brush cells (UBCs) was studied in the cerebellar vermal lobules I-X of the chicken, rat, guinea pig, cat, and monkey using monoclonal mGluR1a antibody as a marker to visualise these recently described nerve cells (Mugnaini and Floris [1994] J. Comp. Neurol. 339:174-180; Mugnaini et al. [1994] Synapse(More)
Immunogold demonstration of GABA was used in ultrathin sections of cerebellar cortex of cat to identify GABA(+) profiles in cerebellar glomeruli. In addition to small, GABA-containing axonal varicosities found at the periphery of all glomeruli, a few complex glomeruli were found to contain a second type of GABA(+) terminal, with a mossy ending appearance.(More)
Quantitative investigation of GABA-immunopositive and GABA-immunonegative neurons was performed in grafts of embryonic tissue of somatosensory cortex, (1) injected intraparenchymally into the barrel field of adult rats (n = 5); (2) placed in an acute cavity in the same area (n = 9); or (3) implanted into the anterior eye chamber (n = 5). Analysis of initial(More)
BACKGROUND Aim of this trial was to test whether heat shock protein peptide DiaPep277 treatment in adult and paediatric patients with recent-onset type 1 diabetes (T1D) is safe and whether it can preserve endogenous insulin production. METHODS Two studies were performed in a prospective, multicentre, double-blind, placebo-controlled trial. Fifty adult(More)
We have investigated the expression of Doublecortin (Dcx) protein in the developing cerebellum of mouse from postnatal 2nd day to postnatal 22nd day and in young adults by immunohistochemistry. Strong expression of Dcx was present in the inner zone of the external granule cell layer, and remained strong while postmitotic granule cell precursors were present(More)
Reorganization of the cerebellar glomerulus, the main synaptic complex within the granule cell layer, was investigated using quantitative morphological techniques. All afferents to the cerebellar cortex, including mossy-fibers, were surgically destroyed by undercutting the cerebellar vermis. Fifteen days after the operation, which resulted in the removal of(More)
RATIONALE 3,4-Methylenedioxymethamphetamine (MDMA, "ecstasy") is a widely used recreational drug known to cause selective long-term serotonergic damage. OBJECTIVES The aim of this study was to characterize the ultrastructure of serotonergic pericarya and proximal neurites in the dorsal raphe nucleus as well as the ultrastructure of serotonergic axons in(More)
Quantitative morphological changes of the developing Purkinje cells were studied from 6 to 90 postnatal (PN) days in the IVth lobule of vermis in the cerebellum of rats. The soma size (mean diameter) of Purkinje cells increased rapidly between 6 PN (on average 10 microns) and 18 PN (about 17 microns) days; it did not change between 18 and 25 PN days, but(More)
Sections of the anterior portion of the visual cortex in the lateral gyrus of the Black Sea porpoise were studied to determine the neuronal architecture and numerical density, and the distribution of neurons immunoreactive to gamma-aminobutyric acid (GABA). Cytoarchitecture and neuronal density are similar to those described in another cetacean, the(More)
Chronic changes in the thalamic mediodorsal nucleus (MD) after unilateral lesions of the prefrontal cortex were studied with the aid of quantitative light, and electron microscopic immunohistochemistry. Three months after the lesions, although the size of MD ipsilateral to the lesion did not change considerably, the neuronal density was significantly(More)
