Clinical application of adult olfactory bulb ensheathing glia for nervous system repair

2011

Abstract The ability of adult olfactory bulb ensheathing glia (OB-OEG) to promote histological and functional neural repair has been broadly documented. Pre-clinical studies show that beneficial effects of adult OB-OEG are repeatable in the same type of spinal cord injury initially tested, in other spinal cord and CNS injury models, in different species and after the administration of these cells in different forms (either alone or in combination with other cells, drugs, products or devices). These studies demonstrate the reproducibility, robustness, fundamental nature and relevance of the findings. Therefore, the use of adult OB-OEG for spinal cord injury repair meets the scientific criter…

Fiber Connections of the Amygdaloid Formation of the Lizard <i>Podarcis hispanica</i>

1993

The amygdaloid formation of the lizard Podarcis hispanica can be divided into three main groups of nuclei on the basis of their input from the main and accessory olfactory bulbs: the vomeronasal amygdala, the olfactory amygdala and the dorsal amygdaloid group, the latter group receiving afferents from neither the main (MOB) or the accessory olfactory bulb (AOB). The vomeronasal amygdala has a centrifugal projection to the AOB, an important commissural connection to the contralateral vomeronasal amygdala, a minor projection to nucleus accumbens, and a bilateral projection to the lateral cortex. The olfactory amygdala displays a bilateral afferents from the MOB, receives a contralateral affer…

Non-steroidal anti-inflammatory drugs in Parkinson’s disease

2007

Parkinson's disease (PD) is known to be a chronic and progressive neurodegenerative disease caused by a selective degeneration of dopaminergic (DAergic) neurons in the substantia nigra pars compacta (SNc). A large body of experimental evidence indicates that the factors involved in the pathogenesis of this disease are several, occurring inside and outside the DAergic neuron. Recently, the role of the neuron–glia interaction and the inflammatory process, in particular, has been the object of intense study by the research community. It seems to represent a new therapeutic approach opportunity for this neurological disorder. Indeed, it has been demonstrated that the cyclooxygenase type 2 (COX-…

Intraepidermal morphologic manifestations in lysosomal diseases.

1989

This paper reports the ultrastructural findings for the epidermis of biopsied skin specimens in numerous lysosomal diseases, which can be grouped as follows: a) presence of vacuolar lysosomal residual bodies in mucopolysaccharidoses I, II and III, Salla disease, GM 2 -gangliosidoses and infantile type II glycogenosis; b) avacuolar lysosomal residual bodies in Niemann-Pick disease type C, mucolipidosis IV, Farber disease, Fabry disease, and late infantile and juvenile neuronal ceroid-lipofuscinoses; c) absence of lysosomal residual bodies in GM 2 -gangliosidoses, metachromatic leukodystrophy, Gaucher disease and sialidosis type III Whenever possible, a biopsy of the skin for morphological di…

Blood Brain Barrier Compromise with Endothelial Inflammation may Lead to Autoimmune Loss of Myelin during Multiple Sclerosis

2009

Multiple sclerosis is an autoimmune disease characterized by multifocal areas of inflammation and demyelination within the central nervous system. The mechanism that triggers the disease remains elusive. However, recent findings may indicate that multiple sclerosis, at its source, could be a hemodynamic disorder. It has been found that multiple sclerosis patients exhibit significant stenoses in extracranial veins draining the central nervous system (in azygous and internal jugular veins), which are associated with significant pressure gradients measured across strictures. Such anatomic venous abnormalities were not found in the control group of healthy subjects. In this review, it is hypoth…

Manual segmentation qualification platform for the EADC-ADNI harmonized protocol for hippocampal segmentation project

2015

The use of hippocampal volumetry as a biomarker for Alzheimer's disease (AD) requires that tracers from different laboratories comply with the same segmentation method. Here we present a platform for training and qualifying new tracers to perform the manual segmentation of the hippocampus on magnetic resonance images (MRI) following the European Alzheimer's Disease Consortium and Alzheimer's Disease Neuroimaging Initiative (EADC-ADNI) Harmonized Protocol (HarP). Our objective was to demonstrate that the training process embedded in the platform leads to increased compliance and qualification with the HarP.Thirteen new tracers' segmentations were compared with benchmark images with respect t…

Stem Cell Populations and Regenerative Potential in Chronic Inflammatory Lung Diseases

2009

Several acute and chronic inflammatory pathologies of the lung are accompanied by structural modifications of airway mucosa that vary depending on the severity, duration and type of the disease. These morphological changes, that determine organ dysfunction, are not always reversible. Indeed, the cycle of injury and repair, influencing airway wall re- generation, may sometimes break off and an exacerbation of the pathology may occur. The mechanisms at the base of airway remodelling during inflammation have been widely studied and numerous evidences indicate that the molecular dialogue among the cells of the mucosa has an essential role in orchestrating cell differentiation and tissue repair.…
