1. 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

2. Neuroprotective effects of erythropoietin on rat retinas subjected to oligemia
OBJECTIVES: Erythropoietin may have neuroprotective potential after ischemia of the central nervous system. Here, we conducted a study to characterize the protective effects of erythropoietin on retinal ganglion cells and gliotic reactions in an experimentally induced oligemia model. METHODS: Rats were subjected to global oligemia by bilateral common carot

3. Glial scar-modulation as therapeutic tool in spinal cord injury in animal models
Abstract Purpose: Spinal Cord injury represents, in veterinary medicine, most of the neurological attendances and may result in permanent disability, death or euthanasia. Due to inflammation resulting from trauma, it originates the glial scar, which is a cell interaction complex system. Its function is to preserve the healthy circuits, however, it creates

4. Rescuing axons from degeneration does not affect retinal ganglion cell death
After a traumatic injury to the central nervous system, the distal stumps of axons undergo Wallerian degeneration (WD), an event that comprises cytoskeleton and myelin breakdown, astrocytic gliosis, and overexpression of proteins that inhibit axonal regrowth. By contrast, injured neuronal cell bodies show features characteristic of attempts to initiate the r

5. Reduced occurrence of programmed cell death and gliosis in the retinas of juvenile rabbits after shortterm treatment with intravitreous bevacizumab
OBJECTIVE: Bevacizumab has been widely used as a vascular endothelial growth factor antagonist in the treatment of retinal vasoproliferative disorders in adults and, more recently, in infants with retinopathy of prematurity. Recently, it has been proposed that vascular endothelial growth factor acts as a protective factor for neurons and glial cells, particu

6. Serum and cerebrospinal fluid S100B concentrations in patients with neurocysticercosis
The clinical manifestations of neurocysticercosis (NC) are varied and depend on the number and location of cysts, as well as on the host immune response. Symptoms usually occur in NC when cysticerci enter a degenerative course associated with an inflammatory response. The expression of brain damage markers may be expected to increase during this phase. S100B

7. Congenital hidranencephaly and cerebellar hypoplasia in water buffaloes / Hidranencefalia e hipoplasia cerebelar congênita em búfalos Murrah
Hereditary hydrancephaly and cerebellar hypolasia are reported in Murrah buffalos. Six calves, one female and 5 male out of 128 born between 2004 and 2008 in a farm in southern Brazil were affected. All affected calves were offspring from the same bull. No affected buffaloes were observed in the descendants of other three bulls used in the farm. Main clinica

8. Influencia do MHC classico (Ia) e não-classico (Ib) e da oxido nitrico sintase induzivel (iNOS) na reação glial e na plasticidade das sinapses apos axotomia periferica / Influence of a classical (Ia) and non-classical (Ib) MHC I and inducible nitric oxide synthase (iNOS) on glial reaction and synaptic plasticity after peripheral axotomy
Após uma lesão de um nervo periférico, astrócitos e microglia tornam-se reativos, desencadeando a chamada gliose reativa. Adicionalmente, uma porcentagem significativa dos botões sinápticos em íntima relação com os motoneurônios é eliminada, sendo este mecanismo associado à ação de fagocitose das células gliais. Recentemente, a expressão de M

9. Principais alterações morfológicas no sistema nervoso central em necrópsias de pacientes HIV positivos realizadas no Hospital Escola da Universidade Federal do Triângulo Mineiro, no periódo de 1989 a 1996.
This is a retrospective study of 92 autopsy case of HIV patients, from a total of 847, realized from January, 1989 through December, 1996, in the Universidade Federal do Triângulo Mineiro, Uberaba MG. The objective was to valuated the lesions in the central nervous system (CNS) before the introduction of HAART (highly active antiretroviral therapy). The med

10. Herpesvirus simplex Type 1 (HSV-1) in marmosets (Callithrix jacchus and Callithrix penicillata) - Pathological and molecular characterization / Herpesvirus simplex Tipo 1 (HSV-1) em sagüis (Callithrix jacchus e Callithrix penicillata) - Caracterização anatomopatológica e molecular
The introduction of wild animals in the conviviality with humans represents serious risk to the health of both. The objective of this work was to prove the hypothesis of the HSV-1 is the agent of vesicular and ulcerative lesion in the skin and mucous membranes, associated with neurological signs observed in marmosets in Brazil. Six white-tufted-ear marmosets

11. Características das encefalites em autópsias - aspectos epidemiológicos e morfológicos.
The term encephalitis means inflammation of encephalic parenquima. Among the possible ethiologies of the illness, we detach the infectious one, that among other agents may be caused by virus, fungi, bacteria, protozoary and metazoary. In this retrospective study, the aim was describes the epidemiologic and morphologic characteristics of encephalitis in patie
