1. Avaliação da atividade neuroprotetora da Parawixina 11 isolada da peçonha da aranha Parawixia bistriata (Araneae, Araneidae), em ratos Wistar submetidos a um modelo de glaucoma agudo / Neuroprotective activity analysis of Parawixin 11, isolated from Parawixia bistriata (Araneae, Araneidae) spider venom, in Wistar rats submitted to an model of acute glaucoma
Glaucoma is defined as a typical optic neuropathy characterized by ganglion cells loss and consequent optic nerve damage, resulting in a gradual reduction of the visual field and eventual blindness. In regard to compounds present in spider venoms, they represent an interesting source of bioactive molecules and the study about the possible neuroprotective eff

2. POLIOENCEFALOMALACIA EM RUMINANTES / POLIOENCEPHALOMALACIA IN RUMINANTS
In the first portion of this thesis, epidemiology, clinical signs and distribution of lesions in the brain of thirty one cases of polioencephalomalacia (PEM) in cattle from the Southern (13 cases) and Midwestern (18 cases) Brazil were studied. Morbidity (0.04%-6.66 %), mortality (0.04%-6.66 %), and lethality (50%-100%) rates were similar in both regions stud

3. O MODELO DESMIELINIZANTE DO BROMETO DE ETÍDIO (BE): ESTUDOS MORFOLÓGICOS EM CAMUNDONGOS C57BL/6 NORMAIS E KNOCKOUT PARA CONEXINA 32 / ETHIDIUM BROMIDE (EB) DEMYELINATING MODEL: MORPHOLOGIC STUDIES IN C57BL/6 NORMAL AND CX 32 KNOCKOUT MICE
Light and ultraestructural changes of central and peripheral nervous system lesions in mice KO for connexin-32 and submitted to the ethidium bromide gliotoxic demyelinating model are described. Their KO condition was tested with PCR and a negative connexin-32 labelling was performed by immunofluorescence. The experimental animals were C57BL/6 normal mice and

5. Brain transplants of cells expressing the carboxyl-terminal fragment of the Alzheimer amyloid protein precursor cause specific neuropathology in vivo.
PC12 cells transfected with retroviral recombinants expressing the carboxyl-terminal 104 amino acids of the Alzheimer amyloid protein precursor (beta APP-C104) or PC12 cells transfected with the retroviral vector (DO) alone were transplanted into the brains of newborn mice. At 20 days after grafting, transplants could be detected in all of the mouse brains e

6. Quantitative neuropathology by high resolution magic angle spinning proton magnetic resonance spectroscopy
We describe a method that directly relates tissue neuropathological analysis to medical imaging. Presently, only indirect and often tenuous relationships are made between imaging (such as MRI or x-ray computed tomography) and neuropathology. We present a biochemistry-based, quantitative neuropathological method that can help to precisely quantify information

7. Cell Therapy in Huntington's Disease
Summary: Huntington's disease is an autosomal dominant genetic disease, which results in progressive neuronal degeneration in the neostriatum and neocortex, and associated functional impairments in motor, cognitive, and psychiatric domains. Although the genetic mutation is identified, involving an abnormal CAG expansion within the htt gene on chromosome 4, t

8. Natural and experimental oral infection of nonhuman primates by bovine spongiform encephalopathy agents
Experimental lemurs either were infected orally with the agent of bovine spongiform encephalopathy (BSE) or were maintained as uninfected control animals. Immunohistochemical examination for proteinase-resistant protein (prion protein or PrP) was performed on tissues from two infected but still asymptomatic lemurs, killed 5 months after infection, and from t

9. Disruption of circadian regulation by brain grafts that overexpress Alzheimer beta/A4 amyloid.
Alzheimer disease patients exhibit irregularities in the patterns of normally circadian (daily) rhythms. Alzheimer-type pathology has been reported in the hypothalamus and in the suprachiasmatic nuclei, the putative site of the circadian oscillator. We examined the relationship between the neuropathology of Alzheimer disease, as modeled by an animal system,

10. Theiler's Virus Infection: a Model for Multiple Sclerosis
Both genetic background and environmental factors, very probably viruses, appear to play a role in the etiology of multiple sclerosis (MS). Lessons from viral experimental models suggest that many different viruses may trigger inflammatory demyelinating diseases resembling MS. Theiler's virus, a picornavirus, induces in susceptible strains of mice early acut

11. Three hamster species with different scrapie incubation times and neuropathological features encode distinct prion proteins.
Given the critical role of the prion protein (PrP) in the transmission and pathogenesis of experimental scrapie, we investigated the PrP gene and its protein products in three hamster species, Chinese (CHa), Armenian (AHa), and Syrian (SHa), each of which were found to have distinctive scrapie incubation times. Passaging studies demonstrated that the host sp
