Human monocytes tolerant to LPS retain the ability to phagocytose bacteria and ...
Fernandes,M.L.; Mendes,M.E.; Brunialti,M.K.C.; Salomão,R.Tolerance to lipopolysaccharide (LPS) occurs when animals or cells exposed to LPS become hyporesponsive to a subsequent challenge with LPS. This mechanism is believed to be involved in the down-regulation of cellular responses observed in septic patients. The aim of this investigation was to evaluate LPS-induced monocyte tolerance of healthy volunteers using whole blood. The detection of intracellular IL-6, bac...
Effect of sodium and nitrogen on yield function of irrigated maize in Southern ...
Ramos, Tiago; Gonçalves, M.C.; Castanheira, N.L.; Martins, J.C.; Santos, F.L.; Fernandes, M.L.Salinization and nitrate leaching are two of the leading threats to the environment of the European Mediterranean regions. Inefficient use of water and fertilizers has led to a nitrate increase in the aquifers and reduction in crop yields caused by salts. In this study, a triple emitter source irrigation system delivers water, salt (Na+), and fertilizer (N) applications to maize (Zea mays L.). The objective of ...
Correlatos bioquímicos da depressão em crianças
Queiroz,E.A.; Lombardi,A. B.; Furtado,C.R.H. Santos; Peixoto,C. C. D.; Soares,T. A.; Fabre,Z. L.; Basques,J. C.; Fernandes,M. L. M.; Lippi,J. R. S.O grau de depressão em 88 crianças abandonadas foi analisado por escala de avaliação de depressão adaptada para crianças na pré-puberdade. Os itens da escala foram agrupados em três dimensões: sociológico-relacional, psicológica e biológica. Em 46 crianças desta amostra foram dosados o Cortisol plasmático e a excreção urinária de. catecolamina, VMA, HVA e 5-HIAA. Pela análise dos principais componentes, mostrar...
The diversity of Staphylococcus aureus strains isolated in a Lisbon hospital ov...
Cristino, J M; Laboratório de Microbiologia, Faculdade de Medicina de Lisboa.; Fernandes, M L; Garcia, T; Serrano, N; Salgado, M JOver a 4-year period, 2020 Staphylococcus aureus strains isolated in Santa Maria Hospital were studied, 26.3% of which were methicillin-resistant (MRSA). The main specimens from which the strains were isolated included pus, blood and sputum/bronchial secretions. Isolation in blood cultures was the most common source among patients from medical units. Antimicrobial susceptibility studies showed that while in met...
