Development of polyurethane antimicrobial coatings by composition with phenolic...
Costa, Tiago; Veiga, Maria I.; Osório, Nuno S.; Neves, N. M.; Aguilar, Helena; Fraga, Alexandra G.Microorganisms can be found in almost all environments with high-touch surfaces being an important fomite for microbial growth. Considering the health issues associated to acquired infection from inanimate surfaces, as well as the raising hygienic concerns, the incorporation of antimicrobial compounds in high-touch surfaces emerges as an effective solution for biomedical and common daily applications. In this w...
CMOS spectrophotometric microsystem for malaria detection
Ferreira, Gabriel Malheiro; Baptista, Vitória; Silva, Vitor; Veiga, Maria I.; Minas, Graça; Catarino, Susana OliveiraObjectives: Optical spectrophotometry has been explored to quantify Plasmodium falciparum malaria parasites at low parasitemia, with potential to overcome the limitations of detection in the current diagnostic methods. This work presents the design, simulation and fabrication of a CMOS microelectronic detection system to automatically quantify the presence of malaria parasites in a blood sample. Methods: The de...
Prevalence of resistance associated polymorphisms in Plasmodium falciparum fiel...
Ghanchi, Najia Karim; Ursing, Johan; Beg, Mohammad A.; Veiga, Maria I.; Jafri, Sana; Martensson, AndreasBackground: Scarce data are available on Plasmodium falciparum anti-malarial drug resistance in Pakistan. The aim of this study was, therefore, to determine the prevalence of P. falciparum resistance associated polymorphisms in field isolates from southern Pakistan. Methods: Blood samples from 244 patients with blood-slide confirmed P. falciparum mono-infections were collected between 2005-2007. Single nucleoti...
Drug resistance associated genetic polymorphisms in Plasmodium falciparum and P...
Jovel, Irina T.; Mejia, Rosa E.; Banegas, Engels; Piedade, Rita; Alger, Jackeline; Fontecha, Gustavo; Ferreira, Pedro E.; Veiga, Maria I.Background: In Honduras, chloroquine and primaquine are recommended and still appear to be effective for treatment of Plasmodium falciparum and Plasmodium vivax malaria. The aim of this study was to determine the proportion of resistance associated genetic polymorphisms in P. falciparum and P. vivax collected in Honduras. Methods: Blood samples were collected from patients seeking medical attention at the Hospi...
