13. Systematization, description and territory of the middle and rostral cerebral arteries in broad-snouted caimans (Caiman latirostris)
Background: Information on the arterial vascularization of the broad-snouted caimans’ brain (Caiman latirostris), a specie from the Brazilian fauna, is inexistent and the literature consulted yielded only one description about the development of embryonic circulation and post-birth cerebrovascular alterations in the brain of three caymans. The objective of

14. The modified 2VO ischemia protocol causes cognitive impairment similar to that induced by the standard method, but with a better survival rate
Permanent bilateral occlusion of the common carotid arteries (2VO) in the rat has been established as a valid experimental model to investigate the effects of chronic cerebral hypoperfusion on cognitive function and neurodegenerative processes. Our aim was to compare the cognitive and morphological outcomes following the standard 2VO procedure, in which ther

16. Aplicação clínica da ultra-sonografia craniana com doppler em crianças prematuras de muito baixo peso
Transcranial Doppler sonography is the technique more designate to detect intracranial hemorrhage (ICH) and periventricular leukomalacia (PVL) among preterm. This technique evidence the most important cerebral arteries, mainly arteries the circle of Willis, obtaining blood flow arteries resistance index (RI), becoming upset in cranial hemorrhage and hypoxic-

17. Assessment of blood flow in perforating arteries during intracranial aneurysm surgery with intraoperative videoangiography using indocyanine green / Avaliação do fluxo sanguíneo em artérias perfurantes durante a cirurgia de aneurismas intracranianos através da video-angiografia intra-operatória utilizando indocianina verde
Background. Perforating arteries are commonly involved during the surgical dissection and clipping of intracranial aneurysms. Occlusion of perforating arteries may be responsible for ischemic infarction and poor outcome. The goal of this study was to describe the usefulness of near-infrared indocyanine green videoangiography (ICGA) for the intraoperative ass

18. Sistematização das artérias da base do encéfalo, distribuição e territórios das artérias cerebrais rostral, média e caudal e da artéria mesencefálica na superfície do encéfalo em jacaré do papo-amarelo (Cayman latirostris)
Foram utilizados 30 encéfalos de jacaré do papo-amarelo (Cayman latirostris), injetados com látex, corado em vermelho, com objetivo de sistematizar e descrever a distribuição e territórios das artérias carótidas internas e suas principais ramificações na superfície do encéfalo. As artérias carótidas internas apresentaram uma anastomose intercar

19. Predicting acidemia at birth in pregnancies with abnormal but present end-diastolic flow velocity in umbilical artery / Predição de acidemia ao nascimento em gestações com dopplervelocimetria anormal e fluxo diastólico positivo das artérias umbilicais
No setor de Vitalidade Fetal na Clínica Obstétrica do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo foi conduzido estudo caso-controle com seguimento prospectivo com quarenta e seis pacientes. O objetivo desse estudo foi identificar a associação dos testes de avaliação de vitalidade fetal e acidemia ao nascimento em gest

20. Cerebral perfusion quantification using arterial spin labeling: applications in vascular territories measurement and functional imaging / Quantificação da perfusão sanguínea cerebral utilizando arterial spin labeling: aplicações em medidas de territórios vasculares e em imagens funcionais
Arterial spin labeling techniques allow to obtain quantitative maps of perfusion non-invasively. Along with other MRI techniques, it has proven useful for diagnosis of a variety of cerebrovascular diseases. Amongst the available basic implementations, the continuous approach employing a dedicated labeling RF coil has the advantages of presenting high signal-

21. O fator estimulador de colônias granulocitárias (G-CSF) para isquemia cerebral: uma nova aplicação terapêutica?
G-CSF is a FDA-approved drug, commonly utilized in neutropenic patients, long knows for its anti-inflammatory and angiogenic properties and also for its capacity to mobilize stem cells, hematopoiethic and endogen precursors and progenitor cells. Recently neuroprotective effects have been shown in animals and humans and there are publications mentioning its p

22. Rehabilitation outcome analyses in aneurysmal subaracnhoid hemorrhage patients / Analise dos resultados da reabilitação em pacientes com hemorragia subaracnoide aneurismatica
Subarachnoid hemorrhage results in critical motor and cognitive impairment which leads to dysfunctions causing a negative impact in quality of life. The functional independence measure (FIM) scale is the most widely accepted functional assessment measure in use in the rehabilitation community. The aim of this study was to describe the rehabilitation outcome

23. AvaliaÃÃo do Ãndice tornozelo/braÃo em portadores de esquistossomose mansÃnica hepatoesplÃnica.
In young people with hepatosplenic form of schistosomiasis mansoni (HSM), the serum level total cholesterol, ester cholesterol and blood lecithin: cholesterol acyltransferase (LCAT) level are decreased. The objective of this study, was to evaluate the ankle-arm index (AAI) in HSM subjects, operated and non-operated (groups I and II) and in non-schistosomal s

24. REPERCUSSÃO DA MANOBRA DE HIPERVENTILAÇÃO BREVE SOBRE A HEMODINÂMICA CEREBRAL, SISTÊMICA E ALTERAÇÕES GASOMÉTRICAS EM PACIENTES SOB ASSISTÊNCIA VENTILATÓRIA MECÂNICA / Repercussion of Brief Hyperventilation Manuever on the Cerebral and Systemic Hemodynamic and Gasometric Parameters in Mechanically Ventilated Patients
Measurements of respiratory mechanics, very important to conduct the patient with mechanical ventilation, are obtained with the relaxation of respiratory muscle in sedated or paralyzed patients or through a brief period of hyperventilation (HV), which is possible to decrease the drive ventilation of patient. However, its known that the hyperventilation decre
