1. Case for diagnosis. Dorsal nodule in a 10-year-old male,
Abstract Granular cell tumors (GCTs) are rare soft-tissue neoplasms. GCT immunohistochemistry is positive for S-100, NSE, and CD68. This report describes the case of a 10-year-old male who presented with a dorsal nodule. A biopsy revealed aggregates and sheets of large epithelioid and spindle cells. The cells had abundant eosinophilic granular cytoplasm. Imm

2. Non-functional paraganglioma of urinary bladder managed by transurethral resection
ABSTRACT Purpose As a rare bladder tumor, paraganglioma of the urinary bladder (PUB) is frequently misdiagnosed as bladder cancer, particularly for the non-functional type. To date, transurethral resection remains a controversial treatment for non-functional PUB. This study aimed to identify the clinical features, pathological characteristics, prognosis, a

3. Assessment of the Toxicity of Sub-chronic Low and High Doses of the Bio-insecticide Spinosad on the Liver, Kidney and the Cerebellum in Male Albino Mice
ABSTRACT Spinosad (SPD) is a highly selective insect control product. However, it was reported that SPD has toxicity toward other non-target organisms. This study was conducted to address the toxic effect of two sub-chronic low and high doses; 35 and 350 mg/kg SPD on some biochemical, histological and immunohistochemical parameters of the liver, kidney and c

4. A rare case of ectopic ACTH syndrome originating from malignant renal paraganglioma
SUMMARY Ectopic adrenocorticotropic hormone (ACTH) syndrome is characterized by hypercortisolism due to the hypersecretion of a non-pituitary ACTH-secreting tumor leading to Cushing’s syndrome. Only a few cases have been reported previously as causing ectopic ACTH related to paraganglioma. Herein, we present a case of Cushing’s syndrome, in who was prove

5. Possible roles of COX-1 in learning and memory impairment induced by traumatic brain injury in mice
People who suffer from traumatic brain injury (TBI) often experience cognitive deficits in spatial reference and working memory. The possible roles of cyclooxygenase-1 (COX-1) in learning and memory impairment in mice with TBI are far from well known. Adult mice subjected to TBI were treated with the COX-1 selective inhibitor SC560. Performance in the open f

6. DISTRIBUIÇÃO DA INERVAÇÃO DA RELAXINA -3 NO TECTUM E TEGMENTUM NO RATO SUGERE ENVOLVIMENTO DO NUCLEO INCERTUS EM REDES DEFENSIVAS CENTRAIS. / DISTRIBUTION INNERVATION OF RELAXIN -3 NO TECTUM E TEGMENTUM SUGGESTS THE RAT NUCLEO INCERTUS INVOLVEMENT IN CENTRAL NETWORKS DEFENSIVE.
Nos mamíferos, as divisões tectal e tegmental do tronco cerebral estão envolvidas em mecanismos de atenção e de respostas a estímulos ameaçadores, como os predadores. Esses centros são regulados por conexões ascendentes, mas os detalhes anatômicos e neuroquímicos desta unidade não são totalmente conhecidos. O núcleo incertus (NI) no tegmento po

7. Investigação do efeito neuroprotetor da atorvastatina em um modelo in vitro de toxicidade induzida pelo peptídeo ¿-amiloide
Alzheimer¿s disease is an age-related neurodegenerative disorder characterized by progressive memory loss, inability to perform the activities of daily living and personality changes. AD is characterized histopathologically by the presence of senile plaques, neurofibrillary tangles, synapse loss and neuronal death. Moreover, it is now recognized that neuroi

8. Diagnostic work-up of gastroenteropancreatic neuroendocrine tumors
Neuroendocrine tumors are a heterogeneous group of malignancies that present a diagnostic challenge. The majority of patients (more than 60%) present with metastatic disease at diagnosis. The diagnosis is based on histopathology, imaging, and circulating biomarkers. The histopathology should contain specific neuroendocrine markers such as chromogranin A, syn

9. Efeito benéfico do enriquecimento ambiental sobre o déficit de memória e a plasticidade celular hipocampal em ratos diabéticos tipo 1
O diabetes mellitus tipo 1 (DMT1) tem sido associado com complicações a longo prazo no sistema nervoso central, além dos efeitos periféricos comuns relacionados à doença, causando disfunções cognitivas no encéfalo. Por outro lado, o enriquecimento ambiental (EA) induz mecanismos de plasticidade dependentes da experiência, especialmente no hipocampo

10. Tratamento com taurina e interferon beta influencia a expressão do complexo de histocompatibilidade principal de classe I (MHC I) e a formação de sinapses em células PC12 / Interferon beta and taurine treatment induce major histocompatibility complex class I (MHC I) upregulation and synapse plasticity in PC12 cells
It has been demonstrated that MHC I up regulation by exogenous treatment with interferon beta (IFN beta) influences the glial reaction and the synaptic elimination process. Also, the amino acid taurine has been shown to positively influence neuronal survival and plasticity. Nevertheless, the establishment of an in vitro model for studying the synaptic format

11. An examination of synaptic proteins following chronic haloperidol in a rat model of tardive dyskinesia
Tardive dyskinesia (TD) is a late-onset side effect mainly affecting the orofacial region of patients treated chronically with classic antipsychotic drugs such as haloperidol (HAL). The causes of TD remain unknown. We hypothesized that faulty synaptic re-organization might be related to TD-like syndromes and used the vacuous chewing movements (VCM) model in

12. The immunomodulator glatiramer acetate influences spinal motoneuron plasticity during the course of multiple sclerosis in an animal model
The immunomodulador glatiramer acetate (GA) has been shown to significantly reduce the severity of symptoms during the course of multiple sclerosis and in its animal model - experimental autoimmune encephalomyelitis (EAE). Since GA may influence the response of non-neuronal cells in the spinal cord, it is possible that, to some extent, this drug affects the
