The family Trypanosomatidae of the order Kinetoplastida is characterized by flagellated protozoa that present a kinetoplast. Most of the recognized genera are parasitic protozoa and, depending on host range, have been classified as either monogenetic trypanosomatids (parasitic in a single invertebrate) or digenetic trypanosomatids (parasitic in both invertebrate and vertebrate hosts). Trypanoso...

Energy is a major challenge for the future with important consequences on the economic and political stability, food security, water supply, energy independence, pollution, and global ecosystem. Owing to increased industrial activities and growing population, the reserve of oil and other fossil resources will become, at best, rare, and costly for extraction and commercialization. For these reas...

Large herbivores have been described as agents of change in terrestrial habitats. Their effect on aquatic ecosystems are, however, underexplored. We raise the question whether elephants and hippopotamus potential to significantly alter limnological properties and, indirectly, primary secondary productivity within small shallow freshwaters arid semi-arid African landscapes. In this note we discu...

Deforestation and colonization in Amazônia have attracted substantial attention. This article focuses on an area of 3,000 km2 within the Brazilian State of Rondônia. Two adjacent settlements were compared to assess the role of their different designs in landscape change. Anari was planned following an orthogonal road network. Machadinho was designed with attention to topography in laying out ro...

Thromb Haemost 2007; 97: 3–4 Antioxidative defense mechanisms can balance the formation of reactive oxygen species in a healthy endothelium.These antioxidative processes include scavenging (e.g. by vitamins C and E) or enzymatic degradation (e.g. by superoxide dismutases, catalase, and glutathione peroxidase). If this redox-sensitive equilibrium is altered by increased reactive oxygen species o...

B razilian fetal medicine specialist Manoel Sarno first noticed in July that something was seriously wrong. In just 2 weeks, he diagnosed four cases of microcephaly, a previously rare birth defect in which the baby’s head is too small because the brain fails to fully develop. Sarno, who works at the Federal University of Bahia in Salvador, Brazil, says he typically sees half-a-dozen cases in a ...

(300 words or less): Previous studies in humans and dogs have shown an association between chronic GI signs, histopathologic inflammation, and microbial imbalances in the intestines, especially with inflammatory bowel disease (IBD). Mucosally invasive E. coli strains isolated from affected Boxer dogs are novel in phylogeny, and have and adherent and invasive phenotype (AIEC) similar to strains ...
