1. Truques sensoriais em diferentes tipos de distonia e no espasmo hemifacial
Introduction: The dystonia is a syndrome of sustained involuntary muscle contractions always producing twisting and repetitive movements or abnormal postures. Of all movement disorders associated with basal ganglia dysfunction, dystonia is the least understood in terms of underlying pathophysiology. Recent works revealed that basal ganglia cortico-striatal-t

2. Caracterização histoquímica e imunoistoquímica de áreas telencefálicas da coruja-da-igreja (Tyto alba) / Histochemical and immunohistochemical characterization of forebrain areas in the barn owl (Tyto alba)
Owls possess exceptional visual and auditory capacities. There is only limited information about the neuroanatomy of their forebrain. Thus, we characterized by histo/immunohistochemical techniques the forebrain of the barn owl. The basal ganglia were delineated by their intense immunostaining for DARPP-32 and tyrosine hydroxylase. Primary thalamorecipient se

3. Investigação da ação neuroprotetora do fator neurotrofico ciliar (CNTF) conjugado com peptideo contendo dominio de translocação de proteina (PTD) / Investigation of neuroprotective action of ciliary neurotrophic factor (CNTF) fused to a protein transduction domain (PTD)
Ciliary neurotrophic factor (CNTF) is known as a neuroprotective agent on motoneurons after peripheral nerve section in neonatal rats and adult mice. However, side effects like weight loss and caquexia have limited its clinical use. A promising approach for the avoidance of such side effects is the fusion of a protein transduction domain (PTD) with CNTF. Pre

4. Study of purinergic receptors in glial cells from dorsal root ganglia. / Estudo dos receptores purinérgicos em células gliais do glânglio da raiz dorsal.
Purinergic receptors are expressed and play role in the sinalization between neurons and glia. In dorsal root ganglia the soma of the sensory neurons is surrounded by a layer of satellite glial cells, whose function is unclear. There are evidences that ATP is released by neurons to act on receptors in satellite cells. So far, the nature of the purinergic rec

5. O sistema nervoso periferico na doença de Machado-Joseph : aspectos clinicos e neurofisiologicos / Clinical and neurophysiological study of the peripheral nervous system um Machado-Joseph disease
Machado-Joseph disease or spinocerebellar ataxia 3 (SCA3/MJD) is the most frequent autosomal dominant ataxia in Brazil and caused by an unstable trinucleotide (CAG) repeat expansion in the 10th exon of the MJD1 gene on chromosome 14q. It is a chronic and debilitating neurologic disorder characterized by cerebellar ataxia, pyramidal dysfunction, dystonia, gaz

6. Ultrastructural description of rabies virus infection in cultured sensory neurons
Primary cultures were made from adult mouse spinal ganglia for depicting an ultrastructural description of rabies virus (RABV) infection in adult mouse sensory neuron cultures; they were infected with rabies virus for 24, 36, and 48 h. The monolayers were processed for transmission electron microscopy and immunochemistry studies at the end of each period. As

7. Dexamethasone-induced reactivation of bovine herpesvirus type 5 latent infection in experimentally infected rabbits results in a broader distribution of latent viral DNA in the brain
Bovine herpesvirus type 5 (BHV-5) is a major agent of meningoencephalitis in cattle and establishes latent infections mainly in sensory nerve ganglia. The distribution of latent BHV-5 DNA in the brain of rabbits prior to and after virus reactivation was studied using a nested PCR. Fifteen rabbits inoculated intranasally with BHV-5 were euthanized 60 days pos

8. Apoptosis of sensory neurons and satellite cells after sciatic nerve transection in C57BL/6J mice
The rate of axonal regeneration, after sciatic nerve lesion in adult C57BL/6J mice, is reduced when compared to other isogenic strains. It was observed that such low regeneration was not due just to a delay, since neuronal death was observed. Two general mechanisms of cell death, apoptosis and necrosis, may be involved. By using the terminal deoxynucleotidyl

9. Apoptose de neuronios motores, interneuronios e neuronios sensitivos induzida pela transecção do nervo ciatico em ratos recem nascidos : padrão temporal e efeitos do tratamento com fatores neurotroficos (NGH e CNTF)
Transection of a peripheral nerve in neonatal rats induces an extensive death of axotomized neurons. We demonstrate here that spinal motoneurons and sensory dorsal root ganglia neurons become TUNEL-labeled (tenninal deoxynuc1eotidyl transferase dUTP nick end labelling) afier sciatic nerve transection in neonatal rats, thus indicating that apoptotic mechanism

10. Differentiation of catecholaminergic cells in cultures of embryonic avian sensory ganglia.
From the results of previous studies in which developing peripheral ganglia from quail embryos were transplanted into younger chicken embryo hosts, we concluded that spinal and cranial sensory ganglia contain dormant precursors with autonomic potentialities. Here we describe the differentiation of these precursors in vitro, from dorsal root and nodose gangli

11. Some rat sensory neurons in culture express characteristics of differentiated pain sensory cells.
Sensory neurons were dissociated from trigeminal ganglia or from dorsal root ganglia of rats, grown in culture, and examined for expression of properties of pain sensory cells. Many sensory neurons in culture are excited by low concentrations of capsaicin, reportedly a selective stimulus for pain sensory neurons. Many are excited by bradykinin, sensitized by

12. Biological importance of the retrograde axonal transport of nerve growth factor in sensory neurons.
Nerve growth factor is retrogradely transported in sympathetic and sensory neurons throughout life. Although this transport is known to be biologically significant in sympathetic neurons, such a function was not yet known in sensory ganglia. By using the neuropeptide substance P as a biochemical marker, we show that sensory ganglia from newborn and adult rat
