[Profiles of intestinal polyparasitism in a community of the Colombian Amazon region].

Introduction: Intestinal parasite infections and polyparasitism are highly prevalent in the most vulnerable populations of developing countries due to environmental, biological and social determinants common in the transmission of parasites. Children between 1 and 15 years of age are the most affected population.

Objective: To describe the prevalence and profiles of intestinal polyparasitism in 1 to 15 year-old children from native communities in the Colombian Amazon region.

Molecular Epidemiology of and among Indigenous Children from the Colombian Amazon Basin.

The incidence and prevalence of intestinal parasites in children is most likely due to lack of natural or acquired resistance and differences in behavior and habits closely related to environmental and socioeconomic determinants. The most important protozoa that parasitize humans are , and . These parasites present wide intraspecific genetic diversity and subsequently classified into assemblages and subtypes.

Gold nanoparticles covalently assembled onto vesicle structures as possible biosensing platform.

In this contribution a strategy is shown to covalently immobilize gold nanoparticles (AuNPs) onto vesicle bilayers with the aim of using this nanomaterial as platform for the future design of immunosensors. A novel methodology for the self-assembly of AuNPs onto large unilamellar vesicle structures is described. The vesicles were formed with 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) and 1-undecanethiol (SH).

Herniation of renal pelvis and ureteropelvic junction resulting from superior lumbar triangle hernia.

A 79-year-old female admitted as a result of respiratory insufficiency due to pneumonia presented with a painful swelling in the left lumbar region and acute ureteral colic pain. The diagnosis of Grynfeltt's bilateral hernia was made by means of CT, which revealed herniation in the left side of the renal pelvis and proximal ureter.
