1. Are hemoglobin-derived peptides involved in the neuropsychiatric symptoms caused by SARS-CoV-2 infection?
Follow-up of patients affected by COVID-19 has unveiled remarkable findings. Among the several sequelae caused by SARS-CoV-2 viral infection, it is particularly noteworthy that patients are prone to developing depression, anxiety, cognitive disorders, and dementia as part of the post-COVID-19 syndrome. The multisystem aspects of this disease suggest that mul

2. Charcot's paradox
RESUMO Jean-Martin Charcot (1825-1893), considerado o pai da neurologia moderna, teve sua formação direcionada para a patologia, aprendendo a valorizar achados anatômicos. Entre as principais contribuições de Charcot está o uso do método anatomoclínico aplicado à neurologia. Descrito como frio e impaciente em suas relações interpessoais, Charcot m

3. Hippocampal overexpression of Down syndrome cell adhesion molecule in amyloid precursor protein transgenic mice
Down syndrome cell adhesion molecule (DSCAM) is located within the Down syndrome critical region of chromosome 21. DSCAM is a broadly expressed neurodevelopmental protein involved in synaptogenesis, neurite outgrowth, and axon guidance. We previously demonstrated DSCAM overexpression in the cortex of amyloid precursor protein (APP) transgenic mice, suggestin

4. Tau, APP, NCT and BACE1 in lymphocytes through cognitively normal ageing and neuropathology
Embora a doença de Alzheimer seja um distúrbio do cérebro, uma série de alterações periféricas têm sido encontradas nesses pacientes; no entanto, pouco se sabe sobre como os genes envolvidos na fisiopatologia se expressam nas células periféricas, tais como em linfócitos durante o envelhecimento normal em comparação com o neuropatológico. Analis

5. 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

6. Associação dos níveis de BDNF (brain derived neurotrophic factor) no comprometimento cognitivo leve e na doença de Alzheimer
Background: It has been suggested that there is an association between brain-derived neurotrophic factor (BDNF) and the neuropathology of Alzheimer¿s disease (AD). However, little is known about the role of BDNF in subjects with mild cognitive impairment (MCI). In the present study, we investigated BDNF serum levels in healthy elderly, amnestic MCI, and mil

7. Doença do armazenamento lisossomal causada pela ingestão espontânea de Sida carpinifolia em cervos Sambar (Cervus unicolor) cativos no Rio de Janeiro. / Lysosomal storage disease caused by spontaneous ingestion of Sida carpinifolia in captive-Sambar deer (Cervus unicolor) in Rio de Janeiro State, Brazil.
Cases of diseases induced by toxic plants in domestic herbivores are well reported throughout the world and have been studied also in Brazil. However, not much is known about the epidemiological and pathological aspectos of these conditions in free-living wildlife or bred in captivity. The risk for developing the toxicoses in captivity has been increasing, s

8. 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

9. NEUROPATOLOGIA DA CINOMOSE CANINA / NEUROPATHOLOGY OF CANINE DISTEMPER
Canine distemper is one of the most prevalent viral diseases of dogs. Several cases are diagnosed in a daily basis in private practices and veterinary hospitals around the country. Most cases of neurological manifestation of canine distemper are fatal and the diagnosis confirmation by histopathology is often necessary. Canine distemper encephalitis is the ma

10. Purinergic signalling: past, present and future
The discovery of non-adrenergic, non-cholinergic neurotransmission in the gut and bladder in the early 1960's is described as well as the identification of adenosine 5'-triphosphate (ATP) as a transmitter in these nerves in the early 1970's. The concept of purinergic cotransmission was formulated in 1976 and it is now recognized that ATP is a cotransmitter i

11. Avaliação da expressão gênica na doença de Alzheimer através da técnica de cDNA microarray em amostras de cérebro postmortem humano / Evaluation of the gene expression in Alzheimer´s disease by cDNA microarray approach from human postmortem brain samples
Alzheimers disease (AD) has received intense study during the past decades. The pathophysiology of AD has been clarified but the diagnosis of AD is still imperfect. On one hand, about 20% of patients diagnosed with probable AD are found, at autopsy, to not meet the pathological definition of the disease. On the other hand, why some subjects have high AD neur

12. EPIDEMIOLOGY, CLINICAL SIGNS AND DISTRIBUTION OF ENCEPHALIC LESIONS IN CATTLE AFFECTED BY MENINGOENCEPHALITIS CAUSED BY BOVINE HERPESVIRUS-5 (BoHV-5) / EPIDEMIOLOGIA, SINAIS CLÍNICOS E DISTRIBUIÇÃO DAS LESÕES ENCEFÁLICAS EM BOVINOS AFETADOS POR MENINGOENCEFALITE POR HERPESVÍRUS BOVINO-5 (BoHV-5)
São descritos sete surtos e um caso isolado de meningoencefalite por herpesvírus bovino-5 (BoHV-5) em bovinos no Rio Grande do Sul entre 2002-2004. Foram afetados bovinos de 1-18 meses, de diversas raças e ambos os sexos. A maior freqüência foi observada em bovinos recém-desmamados e submetidos a outros fatores de estresse. Nesses surtos, de uma popula
