1. Neuraxial block anesthetic technique in a patient with SCN8A encephalopathy: case report
Abstract Mutations in SCN8A gene lead to changes in sodium channels in the brain, which are correlated with severe epileptic syndrome. Due to the rarity, there are few studies that support anesthesia in that population. The present study aims to report alternatives to inhalation anesthesia at epileptic encephalopathy. Case report: Male, 4 years old, with SC

2. Anticonvulsant mechanism of saponins fraction from adventitious roots of Ficus religiosa: possible modulation of GABAergic, calcium and sodium channel functions
ABSTRACT In our previous studies, quantified saponins-rich fraction from adventitious root extract of Ficus religiosa L., Moraceae, showed anticonvulsant effect in acute, as well as chronic mice models of epilepsy. The present study was designed to reveal putative anticonvulsant mechanism of quantified saponins-rich fraction using target specific animal mode

3. TRP channels, omega-3 fatty acids, and oxidative stress in neurodegeneration: from the cell membrane to intracellular cross-links
The transient receptor potential channels family (TRP channels) is a relatively new group of cation channels that modulate a large range of physiological mechanisms. In the nervous system, the functions of TRP channels have been associated with thermosensation, pain transduction, neurotransmitter release, and redox signaling, among others. However, they have

4. Estudo imunohistoquímico da composição estrômato-vascular dos pólipos tonsilares / Immunohistochemical study of the stromal and vascular components of the tonsillar polyps
Tonsillar polyps are nonneoplastic lesions usually composed of a variable amounts of lymphoid, vascular and connective tissues. All are generally assumed to be hamartomatous proliferations but the profile of vascular and connective components has yet to be explored. The vascular system of the tonsils is complex and includes highly specialized structures (i.e

5. Desempenho de enlaces sem fio em condições muito severas de desvanecimento e modelagem estatistica de canais de desvanecimento correlacionados e com parametros arbitrarios / Wireless link performance under severe fading condititions and stastical modeling of correlated fading channels with arbitrary parameters
Este trabalho avalia o desempenho de enlaces sem fio em condições muito severas de desvanecimento. Para isso, uma nova distribuição de probabilidade, a ?-µ Extrema, é investigada como modelo de desvanecimento para descrever o sinal propagado em tais condições. Ajustes a dados de campos publicados na literatura e coletados em um ambiente confinado e o

6. Internal communication as a strategic factor in companies with contact center of Greater Florianópolis / A comunicação interna como fator estratégico nas empresas com contact center da grande Florianópolis
Globalization and technological improvement priority, made the way that organizations organize themselves to be changing over time. This made organizations realize the importance of thinking and act in relation to strategic position according to organizational communication especially in relation to internal communication. Moreover, contact centers come to b

7. Tectônica e sedimentação na Bacia do Camaquã Central (RS): exemplos do Grupo Guaritas e do Grupo Santa Bárbara / Tectonics and sedimentation in Central Camaquã Basin: the Guaritas Group and the Santa Bárbara Group
The relationship between tectonics and sedimentation plays a primordial role in the understanding of sedimentary successions. On the other hand, the study of pre-Silurian fluvial deposits represents a challenge due to the lack of interaction between land plants and river systems which characterizes post-Silurian environments. The Camaquã Basin (Ediacaran to

8. Effect of a high fat diet on mitochondria: bioenergetics, K+ transport and redox state / Efeito de dietas hiperlipídicas sobre mitocôndrias de fígado de camundongos: bioenergética, transporte de K+ e estudo redox
Obesity is associated with multiple dysfunctions including dyslipidemia, insulin resistance and diabetes. These malfunctions are associated with modifications in mitochondrial physiology. Furthermore, mitochondria are the most important site of energy metabolism and reactive oxygen species production. Alberici et al. (2006) demonstrated that hypertriglycerid

9. Desenvolvimento de um sistema de aquisiÃÃo e armazenamento de dados microcontrolado
The data acquisition systems are present in many studies, cooperating on collection, storage and analyses of data. On farming field, these systems are used in experiments of agricultural machines, soil characteristics study, as well as in other applications where data collection by sensors is needed. In the present study, a data acquisition system was develo

10. Parental care in four sympatric species of Leptodactylus (Anura, Leptodactylidae) / Cuidado parental em quatro espécies simpátricas de Leptodactylus (Anura; Leptodactylidae)
Maternal care to tadpole shoals occur in four species of Leptodactylus that occur in the Cerrado of the Triângulo Mineiro. Here we described and quantify features of the maternal care for these species. We presented a list of behaviors related performed by the carrying females and determined if, in L. ocellatus, L. podicipinus, and L. cf. leptodactyloides t

11. Contribuições teoricas para o estudo de funções de distribuição correlacionadas em um canal sem fio / Theoretical contributions to the study of correlated distributions funcions of wireless channels
In wireless communications, the multipath fading is modeled by several distributions including Hoyt, Rayleigh, Weibull, Nakagami-m, and Rice. In this thesis, new, exact expressions for the bivariate Hoyt (Nakagami-q) processes with arbitrary correlation in a nonstationary environment are derived. More specifically, the following are obtained: joint probabili

12. Papel de sinais cromáticos na identificação de parceiros sexuais em sagüi comum (callithrix jacchus)
The literature concerning color vision shows a trichromatic advantage in detecting ripe fruits and young leaves, but there are contradictory results. There is also the suggestion of this type of vision being adapted to perceive socio-sexual signals. Indeed, Old World primates utilize the skin color of conspecifics as a factor of attraction. But in New World
