Sexual reproduction of the pentaploid, short-styled Oxalis pes-caprae allows th...
Costa, J.; Ferrero, V.; Loureiro, J.; Castro, M.; Navarro, L.; Castro, S.Reproduction is a key factor for the successful establishment and spread of introduced species. Oxalis pes-caprae is a tristylous species with a self- and morph-incompatibility sexual system that, in the invaded range of the western Mediterranean Basin, has been found to reproduce asexually because only the pentaploid, short-styled morph (5x S-morph) was introduced. The objective of this study was to test the a...
Viability of wall-embedded tag antenna for ultra-wideband real-time suitcase lo...
Zaric, A.; Matos, V. S.; Costa, J. R.; Fernandes, C. A.WOS:000335152600007 (Nº de Acesso Web of Science) ; Viability of a conformal single-layer monopole antenna is studied for a wall-embedded tag in an ultra-wideband (UWB) suitcase localisation application based on impulse radio UWB. The performance of the embedded antenna is simulated and confirmed experimentally in real-time localisation (RTL) experiments carried out in a cluttered laboratory environment. Evalu...
Urinary Estrogen Metabolites and Self-Reported Infertility in Women Infected wi...
Santos, J.; Gouveia, M.J.; Vale, N.; Delgado, M. de L.; Gonçalves, A.; da Silva, J.M.; Oliveira, C.; Xavier, P.; Gomes, P.; Santos, L.L.; Lopes, C.Schistosomiasis is a neglected tropical disease, endemic in 76 countries, that afflicts more than 240 million people. The impact of schistosomiasis on infertility may be underestimated according to recent literature. Extracts of Schistosoma haematobium include estrogen-like metabolites termed catechol-estrogens that down regulate estrogen receptors alpha and beta in estrogen responsive cells. In addition, schis...
A Graphical Aid for the Complex Permittivity Measurement at Microwave and Milli...
Silveirinha, M. G.; Fernandes, C. A.; Costa, J. R.WOS:000337131400021 (Nº de Acesso Web of Science) ; We introduce a novel procedure to retrieve the complex permittivity ϵ'-jϵ'' of dielectric materials. It is a variant of the well-known waveguide method, and uses as input the one-port reflection data from a vector network analyzer connected to a short-circuited rectangular waveguide filled with a dielectric sample of known length. Here, it is shown that for l...
Ânus Ectópico Anterior: Causa «Tratável» de Obstipação Crónica
Tavares, M. L.; Campos, M.; Mariz, C.; Carvalho, J. L.; Costa, J. EstevãoO ânus ectópico anterior é uma entidade clínica subestimada como causa de obstipação crónica na criança.Apresentamos três casos clínicos de ânus ectópico anterior com sintomatologia idêntica, ou seja, obstipação crónica renitente e dificuldade à evacuação de fezes, cujo diagnóstico foi confirmado pela verificação de um recesso posterior ao exame físico e no enema contrastado. O tratamento cirúrgico constou de a...
Multi-dimensional optimization of the incorporation of PCM-drywalls in lightwei...
Soares, N.; Gaspar, A. R.; Santos, P.; Costa, J. J.This paper evaluates the impact of PCM-drywalls in the annual and monthly heating and cooling energy savings of an air-conditioned lightweight steel-framed (LSF) residential single-zone building, considering real-life conditions and several European climates. A multi-dimensional optimization study is carried out by combining EnergyPlus and GenOpt tools. The CondFD-algorithm is used in EnergyPlus to simulate pha...
[15]aneN4S: synthesis, thermodynamic studies and potential applications in chel...
Torres, N.; Gonçalves, S.; Fernandes, A. S.; Machado, J. F.; de Brito, M. J.; Oliveira, N. G.; Castro, M.; Costa, J.; Cabral, M. F.The purpose of this work was to synthesize and characterize the thiatetraaza macrocycle 1-thia-4,7,10,13-tetraazacyclopentadecane ([15]aneN4S). Its acid-base behaviour was studied by potentiometry at 25 °C and ionic strength 0.10 M in KNO3. The protonation sequence of this ligand was investigated by 1H-NMR titration that also allowed the determination of protonation constants in D2O. Binding studies of [15]aneN...
IFNAR1 Controls Progression to Cerebral Malaria in Children and CD8+ T Cell Bra...
Ball, E. A.; Sambo, M. R.; Martins, M.; Trovoada, M. J.; Benchimol, C.; Costa, J.; Antunes Goncalves, L.; Coutinho, A.; Penha-Goncalves, C.Malaria in pregnancy is exquisitely aggressive, causing a range of adverse maternal and fetal outcomes prominently linked to Plasmodium-infected erythrocyte cytoadherence to fetal trophoblast. To elucidate the physiopathology of infected erythrocytes (IE) sequestration in the placenta we devised an experimental system for intravital placental examination of P. berghei-infected mice. BALB/c females were mated to...
Artroplastia Unicompartimental do Joelho Oxford Phase 3. Resultados a Médio Prazo
Falcão, P; Grenho, A; Homero Costa, J; Torrinha Jorge, J; Arcângelo, J; Catarino, PIntrodução: A artroplastia unicompartimental evoluiu nos últimos 40 anos, sendo hoje em dia considerada uma estratégia cirúrgica apropriada para a osteoartrose do compartimento interno da articulação do joelho. Desenvolvimentos nos instrumentos cirúrgicos, desenho do implante, abordagem cirúrgica e selecção dos doentes levaram a uma grande melhoria dos resultados pós-operatórios e aumento da longevidade das pró...
Mannosylglucosylglycerate biosynthesis in the deep-branching phylum Planctomyce...
Cunha, Sofia; Avó, Ana Filipa d’; Mingote, Ana; Lamarosa, Pedro; Costa, M. S. da; Costa, J.The biosynthetic pathway for the rare compatible solute mannosylglucosylglycerate (MGG) accumulated by Rhodopirellula baltica, a marine member of the phylumPlanctomycetes, has been elucidated. Like one of the pathways used in the thermophilic bacterium Petrotoga mobilis, it has genes coding for glucosyl-3-phosphoglycerate synthase (GpgS) and mannosylglucosyl-3-phosphoglycerate (MGPG) synthase (MggA). However, u...
