Effects of glucose and inoculum concentrations on production of bioactive molec...
Serrano, N. F. G.; Mussatto, Solange I.; Rodrigues, L. R.; Teixeira, J. A.; Hokka, C. O.; Sousa, C. P.The composition of culture media and the microbial cell mass influence on secondary metabolites production in fermentative procedures. The effect of two process variables, namely glucose and inoculum concentrations on biomass formation, bioactivity and surface tension of extract obtained during the cultivation of endophytic Paenibacillus polymyxa RNC-D was evaluated. Assays were performed using glucose and inoc...
Preeclampsia: from epidemiological observations to molecular mechanisms
López-Jaramillo,P.; Casas,J.P.; Serrano,N.Preeclampsia is the main cause of maternal mortality and is associated with a five-fold increase in perinatal mortality in developing countries. In spite of this, the etiology of preeclampsia is unknown. The present article analyzes the contradictory results of the use of calcium supplementation in the prevention of preeclampsia, and tries to give an explanation of these results. The proposal of an integrative ...
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...
