1. Glyphosate commercial formulation effects on preoptic area and hypothalamus of Cardinal Neon Paracheirodon axelrodi (Characiformes: Characidae)
ABSTRACT In Colombia the use of glyphosate commercial formulations (Roundup™) for spraying have left deleterious effects on animals and humans. Much of this spraying takes place at the Orinoco basin, habitat of one of the most exported ornamental fish in Colombia, Cardinal neon. To evaluate the effect of Roundup Activo™ four experimental treatments were

2. Franz Nissl (1860-1919), noted neuropsychiatrist and neuropathologist, staining the neuron, but not limiting it
RESUMO Franz Alexander Nissl realizou estudos sobre transtornos mentais e nervosos, como clínico, mas principalmente como patologista, provavelmente o mais importante de seu tempo. Ele reconheceu mudanças nas células gliais, elementos sangüíneos, vasos sangüíneos e tecido cerebral em geral, realizando-o por meio de um corante azul especial desenvolvid

3. Severe Outbreak of Avian Encephalomyelitis in Laying Hens in Northeastern Brazil
ABSTRACT This paper describes the epidemiological, clinical and pathological aspects of an avian encephalomyelitis (AE) outbreak in commercial laying hens in Northeastern Brazil. The disease affected 23,409 layers (from day one until 100 weeks) leading to mortality of 16.5% (5,049/30,600) of the flock. Twenty laying hens were clinically examined, and blood s

4. Abortion in association with transplacental Theileria equi infection in a mare from the State of Espírito Santo, southeast Brazil: case report
RESUMO A piroplasmose equina é transmitida por carrapatos, sendo causada pelos protozoários Babesia caballi e Theileria equi. O objetivo deste trabalho foi relatar um caso de aborto equino associado à piroplasmose fetal. Uma égua gestante, aparentemente saudável, abortou no 10º mês de gestação. Na necropsia do feto, foi observada palidez de subcutâ

5. Systemic dissemination of glioblastoma: literature review
RESUMO INTRODUÇÃO: Glioblastoma (GBM) é o tumor maligno mais comum do sistema nervoso central em adultos. Entretanto, metástase a distância de GBM é um evento extremamente raro. O presente estudo teve o objetivo de realizar uma revisão da literatura para avaliar os possíveis mecanismos biológicos relacionados com a ocorrência de metástase a dist�

6. Mesenteric hypoperfusion and inflammation induced by brain death are not affected by inhibition of the autonomic storm in rats
OBJECTIVES: Brain death is typically followed by autonomic changes that lead to hemodynamic instability, which is likely associated with microcirculatory dysfunction and inflammation. We evaluated the role of the microcirculation in the hemodynamic and inflammatory events that occur after brain death and the effects of autonomic storm inhibition via thoraci

7. Selenium protects cerebral cells by cisplatin induced neurotoxicity
PURPOSE:To evaluate the central nervous system toxicity of cisplatin and neuroprotective effect of selenium.METHODS:Twenty-one male Wistar albino rats were divided into three groups: control (C), cisplatin (CS), cisplatin and selenium (CSE, n=7 in each group). Cisplatin (12 mg/kg/day, i.p.) was administered to CS and CSE groups for three days. Furthermore, C

8. Case for diagnosis
The Osler-Weber-Rendu syndrome or Hereditary Hemorrhagic Telangiectasia (HHT) is a systemic fibrovascular dysplasia characterized by defects in the elastic and vascular walls of blood vessels, making them varicose and prone to disruptions. Lesions occur in different organs and can lead to hemorrhage in the lungs, digestive tract and brain. We describe the ca

9. Laparoscopic resection of tumor recurrence after radical nephrectomy for localized renal cell carcinoma
Introduction Local recurrence of Renal Cell Carcinoma (RCC) after radical nephrectomy is a rare event. Some known risk factors are: clinical/pathological stage, locorregional disease and lyimph node positivity. Since up to 30-40% of patients can achieve a disease-free status, we show a case (video) in which we performed a laparoscopic excision of a local RCC

10. Desenvolvimento de metodos opticos para o estudo do acoplamento neuro-vascular-metabolico intrinseco a dinamica cerebral / Development of optical methods to the study of neuro-metabolic-vascular coupling underlying cerebral dynamics
Task-associated neuronal activity leads to a complex chain of biological events within the brain. The increased energetics gives rise to elevated glucose and oxygen consumption in the tissue. Biochemical and neuronal factors induce changes in blood vessels and variations in blood ow, volume and oxygenation. Although it has been extensively investigated, this

11. Distribution of microglial cells in the cerebral hemispheres of embryonic and neonatal chicks
The distribution, morphology and morphometry of microglial cells in the chick cerebral hemispheres from embryonic day 4 (E4) to the first neonatal day (P1) were studied by histochemical labeling with a tomato (Lycopersicon esculentum) lectin. The histochemical analysis revealed lectin-reactive cells in the nervous parenchyma on day E4. Between E4 (5.7 ± 1.3

12. CEREBRAL ANGIOGRAPHY IN DOGS (Canis familiaris) / ANGIOGRAFIA CEREBRAL EM CÃES (Canis familiaris)
Cerebral angiography is radiological procedure to demonstrate areas of the vascular supply of the brain through the injection of a positive contrast where proper visualization of the blood stream is obtained. In this experiment, twenty adult dogs were submitted to a cerebral angiography. In the operation room, under general anesthesia, the left carotid arter
