1. Feline lymphoma in the nervous system: pathological, immunohistochemical, and etiological aspects in 16 cats
RESUMO: Os aspectos patológicos, imuno-histoquímicos (IHQ) e etiológicos do linfoma envolvendo o sistema nervoso de felinos foram analisados através de um estudo retrospectivo (período de 2004-2017) no Estado do Rio Grande do Sul, Brasil. O envolvimento do sistema nervoso foi observado em 16 (12,2%) dos 125 felinos com linfoma desse estudo e afetou prin

2. A rare mediastinal occurrence of neuroblastoma in an adult: case report
ABSTRACT CONTEXT: Neuroblastoma is the most common extracranial malignant solid tumor that occurs during childhood. It arises from primitive cells and is seen in the adrenal medulla and sympathetic ganglia of the sympathetic nervous system. CASE REPORT: We present a rare case of a 40-year-old man who was diagnosed with the onset of neuroblastoma arising

3. Vascular supply of the central nervous system of the land snail Megalobulimus oblongus (Gastropoda, Pulmonata)
The vascularization of the central nervous system of the snail Megalobulimus oblongus was studied by injection of carmine-gelatin solution into the arterial system and using a histochemical technique for the detection of alkaline phosphatase. The central nervous system of M. oblongus is irrigated by the anterior aorta, from which a series of small branches e

4. The gross anatomy of the nervous system of Bothriurus bonariensis (L.C.Koch, 1842) (Scorpiones, Bothriuridae)
O sistema nervoso da ordem Scorpiones parece apresentar um plano comum de organização. Uma abordagem anatômica, utilizando o azul de metileno como meio contrastante para o tecido nervoso, e histológica, por intermédio das técnicas da hematoxilina-eosina e hematoxilina férrica de Heindenhain, permitiu identificar um grande número de nervos em B. bonar

5. Anandamide injected into the lateral ventricle of the brain inhibits submandibular salivary secretion by attenuating parasympathetic neurotransmission
Our objective was to determine the effect of arachidonylethanolamide (anandamide, AEA) injected intracerebroventricularly (icv) into the lateral ventricle of the rat brain on submandibular gland (SMG) salivary secretion. Parasympathetic decentralization (PSD) produced by cutting the chorda tympani nerve strongly inhibited methacholine (MC)-induced salivary s

6. Análise histológica e morfométrica de componentes neuroendócrinos do intestino delgado do gambá Didelphis aurita (Wied-Neuwied, 1826) / Hystological analysis and morphometry of the neuroendocrine componentes of the small intestine of the opossum Didelphis aurita (Wied-Neuwied, 1826)
The objectives of this work were to aspects of the histology and morphometry of the small intestine of adult and post- puberty big-eared opossum Didelphis aurita. The morphometric description of the speciess small intestine focused on the mucous, sub-mucous and muscular layers. The entero- endocrinal-cells and the cells of the myoenteric nervous and sub-muco

7. Histological survey of protocerebral areas and retrocerebral complex of Melipona quadrifasciata anthidioides workers (Hymenoptera, Apidae, Meliponini) / Mapeamento histológico das áreas protocerebrais e do complexo retrocerebral de operárias de Melipona quadrifasciata anthidioides (Hymenoptera, Apidae, Meliponini)
The stingless bees colony comprises a queen, workers of diferent ages that perform different tasks and males only present before the queen´s fecundation. Among the workers, only the oldest ones foragers keep a direct contact with the light/dark environmental cycle. Biological rhythms are present and are generated by the circadian system located in the centr

8. Cloning and expression analysis of the transcription factor Scratch2 during the chicken early embryogenesis. / Clonagem e análise da expressão do fator de transcrição Scratch2 durante a embriogênese inicial de galinha.
In invertebrates, the Scratch (Scrt) genes encode transcription factors that promote neurogenesis during development. The Scrt function in vertebrates is unknown, but in mice Scrt1 and Scrt2 are specifically expressed in post-mitotic neurons in the embryo and in the adult central nervous system. In this work, we have cloned the coding sequence of chicken Scr

9. 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

10. Anatomic variation of cranial parasympathetic ganglia
Having broad knowledge of anatomy is essential for practicing dentistry. Certain anatomical structures call for detailed studies due to their anatomical and functional importance. Nevertheless, some structures are difficult to visualize and identify due to their small volume and complicated access. Such is the case of the parasympathetic ganglia located in t

11. Inhibition mechanism of the nicotinic acetylcholine receptor α3β4 tacrine / Mecanismos de inibição do receptor nicotínico de acetilcolina α3β4 pela tacrina
Neuronal nicotinic acetylcholine (cholinergic) receptors (nAChRs) are integral membrane proteins and belong to the family of ligand-gated cation channels composed by α and β subunits. These receptors play a key role in the signal transmission between neurons in the central and peripheral nervous system. The α3β4 subtype, for example, is t

12. 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
