13. Síntese, caracterização microestrutural e elétrica de compostos cerâmicos à base de soluções sólidas de titanato de estrôncio, titanato de cálcio e óxido de ferro / Synthesis, microstructural and electrical characterization of ceramic compounds based on strontium and calcium titanates and iron-oxide
CaxSr1-xTi1-yFeyO3-δ, x = 0, 0.5 and 1.0, y = 0 and 0.35, ceramic compounds were synthesized by reactive solid state synthesis of CaCO3, SrCO3, TiO2 and Fe2O3, and by the polymeric precursor technique. The ceramic powders were evaluated by thermogravimetry and differential thermal analysis, X-ray diffraction and scanning electron microscopy. Sintered c

15. Em busca da região epileptiforme em pacientes com epilepsia do lobo temporal: métodos alternativos baseados em fMRI e EEG-fMRI / Searching for epileptiform region in patients with temporal lobe epilepsy: alternative methods based on fMRI and EEG-fMRI
Temporal lobe epilepsy (TLE) is the most common and resistant form of epilepsy to anti-epileptic drug. There are several types of anti-epileptic drugs used in seizure control. However, in some cases drug treatment is not effective and surgery to remove the epileptogenic zone (EZ) is a recommended alternative. EZ is a theoretical concept and there are many te

16. Central chemoreceptors and neural mechanisms of cardiorespiratory control
The arterial partial pressure (P CO2) of carbon dioxide is virtually constant because of the close match between the metabolic production of this gas and its excretion via breathing. Blood gas homeostasis does not rely solely on changes in lung ventilation, but also to a considerable extent on circulatory adjustments that regulate the transport of CO2 from i

17. Suino como modelo experimental na pesquisa biomédica: valores fisiológicos normais
Background: The use of animals in biomedical research is of great importance. It is fundamental for the development and improvement of new practices and technologies. The selection of the species must take into consideration the practicality of handling and the suitability for the experiment, and it must have low operational costs. Swine are important as an

18. Esclerose lateral amiotrofica : estudo prospectivo de parametros respiratorios / Amyotrophic lateral sclerosis : prospectivestudy on respiratory parameters
The objective of this study was to evaluate the respiratory function of patients with amyotrophic lateral sclerosis (ALS), using the parameters of spirometry, maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP), arterial blood gases and pulse oximetry, and monitor them during the period of 8 months. The study was crosssectional assessmen

19. Condutividade elétrica da solução sólida céria-zircônia dopada com ítrio e gadolínio / Electrical conductivity of solid solution ceria-zirconia doped yttria and gadolinium
Rare earth doped ceria has a great potential to be used as electrolyte in temperatures around 800 C in fuel cells due to its higher electrical conductivity than YSZ. However, the reduction of Ce+4 to Ce+3 in low oxygen partial pressure has introduced limitations for using doped ceria electrolyte due to electronic conduction. Among the several ceria solid sol

20. Is persistent hypotension after transient cardiogenic shock associated with an inflammatory response?
We evaluated the recovery of cardiovascular function after transient cardiogenic shock. Cardiac tamponade was performed for 1 h and post-shock data were collected in 5 domestic large white female pigs (43 ± 5 kg) for 6 h. The control group (N = 5) was observed for 6 h after 1 h of resting. During 1 h of cardiac tamponade, experimental animals evolved a low

21. Effects of pentoxifylline on TNF-alpha and lung histopathology in HCL-induced lung injury
OBJECTIVE: To evaluate the effects of pentoxifylline on hydrochloric acid-induced lung lesions in rats subjected to mechanical ventilation. METHODS: Twenty male, adult Wistar-EPM-1 rats were anesthetized and randomly grouped (n=5 animals per group) as follows: control-MV (mechanical ventilation, MV group); bilateral instillation of HCl (HCl group); bilateral

22. ProduÃÃo de gÃs de sÃntese por tri-reforma do metano em reator de leito fixo
The ever increasing availability of natural gas (NG), and the abundant carbonic gas production, via fermentation of most prepared from sugar cane products (sugar cane juice, and molasses), thermoelectric generators, and refineries have enhanced the research interest of these commodities. The indirect NG conversion processes to synthesis gas (CO and H2), the

23. AVALIAÇÃO DA VENTILOMETRIA E ESPIROMETRIA NO PRÉ E PÓS-OPERATÓRIO DE PACIENTES SUBMETIDOS À CIRURGIA DE HIPERTENSÃO PORTAL
The main goal of the present study is to assess and compare the data obtained from ventilometry, espirometry and vital signs of patients who undergoing DAPE under inhalation anesthesia, and its specific goal is to verify the existence of a co-relation between anesthetic and surgical procedure lengths and pulmonary volumes measured by ventilometry and espirom

24. Morfologia e mecânica pulmonares no curso da infeccão experimental induzida pelo paracoccidioides brasiliensis em camundongos
In the present work, mice BALB/c were infected intravenously with variable yeast cells of P. brasiliensis and were analyzed the morphology and pulmonary mechanics in the course of the experimental infection caused by the fungus, at different occasions (15, 30, 45 and 60 days after infection). Mice were sedated, anesthetized and mechanically ventilated and st
