Efectividade da Rede de Referenciação Perinatal da Região Centro
Costa, E.; Moleiro, P.; Carvalho, L.; Neves, F.; Oliveira, J.; Ventura, A.; Teixeira, A. L.; Martins, J.; Figueiredo, N.; Costa, R.; Peixoto, J.Resumo Em 1990 foi desenvolvida em Portugal uma Rede de Referenciação Perinalal, com definição dos limites e as responsabilidades assistenciais dos Hospitais de Apoio Perinatal Diferenciado (HAPD) e dos Hospitais de Apoio Perinatal (HAP). Graças ao espírito de cooperação c complementaridade desenvolvidos, os critérios de transferência iu útero e pós natal estão bem estabelecidos* Com os resultados do Registo Na...

Características clínicas da fase aguda da infecção experimental de felinos pelo...
Zanutto,M.S.; Froes,T.R.; Teixeira,A.L.; Hagiwara,M.K.A infecção dos felinos pelo Vírus da Imunodeficiência Felina (FIV) resulta no desenvolvimento da síndrome de imunodeficiência dos felinos. Gengivite, perda de peso, linfadenomegalia generalizada, anemia, insuficiência renal crônica, complicações neurológicas, diarréia crônica e infecções bacterianas são encontradas frequentemente. A fase aguda da infecção pode ser assintomática, retardando o estabelecimento do ...
Increased levels of glutamate in the central nervous system are associated with...
Miranda,A.S.; Vieira,L.B.; Lacerda-Queiroz,N.; Souza,A.H.; Rodrigues,D.H.; Vilela,M.C.; Gomez,M.V.; Machado,F.S.; Rachid,M.A.; Teixeira,A.L.Cerebral malaria (CM) is a severe complication resulting from Plasmodium falciparum infection. This condition has been associated with cognitive, behavioral and motor dysfunctions, seizures and coma. The underlying mechanisms of CM are incompletely understood. Glutamate and other metabolites such as lactate have been implicated in its pathogenesis. In the present study, we investigated the involvement of glutam...
Enhanced optical gain clamping for upstream packet based traffic on hybrid WDM/T...
Neto, B.; Klingler, A.; Reis, C.; Dionísio, R. P.; Nogueira, R. N.; Teixeira, A. L. J.; André, P. S.In this paper, we propose a method to mitigate the temporal power transients arising from Erbium doped fiber amplifiers (EDFAs) on packeted/bursty scenario. The technique, applicable on hybrid WDM/TDM-PON for extended reach, is based on a low power clamping provided by a distributed feedback (DFB) laser and a fiber Bragg grating (FBG). An mprovement in the data signal Q factor was achieved keeping the clamping ...
Chemokines in the cerebrospinal fluid of patients with active and stable relaps...
Moreira,M.A.; Souza,A.L.S.; Lana-Peixoto,M.A.; Teixeira,M.M.; Teixeira,A.L.Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the human central nervous system. Although its etiology is unknown, the accumulation and activation of mononuclear cells in the central nervous system are crucial to its pathogenesis. Chemokines have been proposed to play a major role in the recruitment and activation of leukocytes in inflammatory sites. They are divided into subfamilies...
Optical Communications Research at Institute of Telecommunications
Rocha, J. F.; Cartaxo, A. T.; Silva, H. J.; Pinto, J. L.; Teixeira, A. L.; Gameiro, A. S.; Monteiro, P. P.; Pires, J. O.; Ribeiro, R. S.; Violas, M. O.In this contribution we present a brief summary of research activities carried out at Instituto de Telecomunicações (IT, Institute of Telecommunications) in optical communications. These activities cover various aspects related with optical components/subsystems, optical communication systems, and optical networking. ; http://www.informaworld.com/10.1080/01468030590923073
Neural tube defects. The 10-year experience of a central maternity hospital.
Teixeira, A L; Serviço de Pediatria, Maternidade Dr. Alfredo da Costa, Lisboa.; Loreto, H; Machado, M do C; de Almeida, J M1) To determine trends in prevalence of neural tube defects and the impact of therapeutic abortion. 2) To review perinatal management of spina bifida.All spontaneous and therapeutic abortions, still births and live births affected by neural tube defects registered in Alfredo da Costa Maternity in Lisbon, from 1983 to 1992, were retrospectively analysed.Eighty-two cases with neural tube defects are reported and ...
