1. Estudo comparativo entre bibliotecas de implementação para o protocolo SIP / Comparative study of libraries for implementing the sip protocol
A utilização de softwares de videoconferência e VoIP vem se difundindo atualmente. Para que softwares deste tipo, desenvolvidos por empresas diferentes, possam ter interroperabilidade é necessário que sigam um padrão de comunicação. Para este fim existem os protocolos de sinalização. O protocolo de sinalização SIP vem sendo bastante utilizado dev

2. Gateway de voz para integração IP-PSTN aderente à arquitetura das redes de nova geração / Gateway de Voz para Integração IP-PSTN Aderebte à Arquitetura das Redes de Nova Geração
The work presented validates the deployment of a voice gateway for integration between IP networks and the universe of public networks to traditional telephony. The differentiated nature of this Gateway is related to adherence to the functional architecture of next generation networks, through the use of libraries and open platforms, as well as the developme

3. Aberrant signaling in T-cell acute lymphoblastic leukemia: biological and therapeutic implications
T-cell acute lymphoblastic leukemia (T-ALL) is a biologically heterogeneous disease with respect to phenotype, gene expression profile and activation of particular intracellular signaling pathways. Despite very significant improvements, current therapeutic regimens still fail to cure a portion of the patients and frequently implicate the use of aggressive pr

4. Avaliação da qualidade de vídeo em redes IPTV com acesso baseado em ADSL / Video quality assessment in IPTV networks with based ADSL access
In the actual scenary, the growth of the access services demand based on wide band are Strengthening the IPTV services. Thus, the development of a IPTV network architecture project, to adequate to the clients needs and providers objectives, is important to examine the best usages, therefore they will be responsible for the continuity warrant of the supplied

5. Avaliação de feridas crônicas em pacientes atendidos em Unidades Básicas de Saúde de Goiânia / Assessing of chronic wounds in outpatients treated at basic health unit in goiania
Assessing patients with chronic wounds poses a challenge to professionals and doubts still persist concerning characterization of the wound infection status. We believe that the Basic Health Units are in places of reference for the public to submit chronic wounds and should have full attendance and resolution were objectives of this study: characterizing pat

6. Arquitetura e prototipação de uma UNI optica para a rede GIGA / Architecture and prototype of an optical UNI for the GIGA network
The main interests of the GIGA Project are the deployment of Optical Network Technology, Network Services and Applications, Experimental Telecommunication Services and Scientific Applications. In the context of this Project, our research group has been working on the design of an IP/WDMControl Plane to integrate the IP/MPLS Client Network with the Optical Tr

7. Architecture and implementation of a topological information and traffic engineering service to RWA systems / Arquitetura e implementação de um serviço de informações topologicas e de engenharia de trafego para sistemas RWA
GMPLS-controlled all-optical networks are the promise to handle the increasing volume of IP traffic. The GMPLS routing and signaling protocols, mainly OSPF and RSVP, work in such a way that the route calculation for optical circuits does not take into account the wavelength (label) availability. This is not optimal in terms of network resources usage and blo

8. Análise lógica de protocolos, proposta e avaliação de desempenho de um algoritmo de atribuição de rótulo baseado em SRLG em um ambiente GMPLS-WDM. / Protocol logical analysis, proposal and performance evaluation of a label assignment algorithm based on SRLG in a GMPLS-WDM environment.
To satisfy the explosive increasing demands of voice and data traffic, optical networks based on WDM and GMPLS are being developed. The GMPLS´ suite of protocols is currently being considered as the control plane for optical networks and it is compounded of signaling and routing protocols, and also the link management protocol (LMP). The LMP is an important

9. Primary culture and mRNA analysis of human ovarian cells
Established cell lines are invaluable for studying cell and molecular biological questions. A variety of human ovarian cancer (OC) cell lines exist, however, most have acquired significant genetic alterations from their cells of origin, including deletion of important cell cycle regulatory genes. In order to analyze signaling events related to cell cycle con

10. Missense Mutation in the PAS2 Domain of Phytochrome A Impairs Subnuclear Localization and a Subset of Responses
Phytochrome A signaling shows two photobiologically discrete outputs: so-called very-low-fluence responses (VLFR) and high-irradiance responses (HIR). By modifying previous screening protocols, we isolated two Arabidopsis mutants retaining VLFR and lacking HIR. Phytochrome A negatively or positively regulates phytochrome B signaling, depending on light condi

11. Laser microsurgery of higher plant cell walls permits patch-clamp access.
Plasma membranes of guard cells in epidermal peels of Vicia faba and Commelina communis can be made accessible to a patch-clamp pipet by removing a small portion (1-3 micrometers in diameter) of the guard cell wall using a microbeam of ultraviolet light generated by a nitrogen laser. Using this laser microsurgical technique, we have measured channel activity

12. Interleukin-1 stimulates catabolism in C2C12 myotubes
Interleukin-1 (IL-1) is an inflammatory cytokine that has been linked to muscle catabolism, a process regulated by muscle-specific E3 proteins of the ubiquitin-proteasome pathway. To address cellular mechanism, we tested the hypothesis that IL-1 induces myofibrillar protein loss by acting directly on muscle to increase expression of two critical E3 proteins,
