Information on malaria-associated anemia in adult patients is scarce in South American populations. From 2004 to 2006, malaria patients 18 to 45 years of age were recruited in a descriptive cross-sectional study from two different towns: Manaus, in the Brazilian Amazon (120 patients) where Plasmodium falciparum incidence is lower ( approximately 20%), and in Tumaco on the Colombian Pacific Coast (126 patients) where P. falciparum incidence is higher ( approximately 90%).

In this work, we have studied the structural and magnetic properties of yttrium iron garnet nanoparticles doped with copper obtained by sol gel method. The lattice parameter decreases from 12.3779 Å to 12.3774 Å, for low doping and increases from 12.3788 Å to 12.3814 Å for high copper concentrations. The variation in the crystallite size was related with defects and internal stress produced by the dopant addition. The micrographs showed a similar format, rounded irregular form and lengthened, for ...

The fabrication of varied molecular architectures in layer-by-layer (LbL) films is exploited to control the photoluminescence (PL) of poly(p-phenylene vinylene) (PPV) in an unprecedented way. This was achieved by controlling the Förster energy transfer between PPV layers (donors) and layers of a commercial azodye, Brilliant Yellow (BY) (acceptors). Energy transfer was controlled by inserting spacer layers of inert polymers between PPV and BY layers and by photoaligning the BY molecules via trans-cis-trans ...

The basin is a shallow restricted environment which receives large quantities of untreated sewage, and is therefore polluted, eutrophic and hypoxic. The meiofauna were identified to major taxa (nematodes, copepods, polychaetes, oligochaetes, turbellarians, gastrotrichs, rotifers, ostracods, acari, and juvenile amphipods and bivalves) and counted. Subsamples of nematodes were extracted and identified ...
