Physical fitness among urban and rural Ecuadorian adolescents and its association with blood lipids: a cross sectional study.

Background: Physical fitness has been proposed as a marker for health during adolescence. Currently, little is known about physical fitness and its association with blood lipid profile in adolescents from low and middle-income countries. The aim of this study is therefore to assess physical fitness among urban and rural adolescents and its associations with blood lipid profile in a middle-income country.

Avoidance response of Danio rerio to a fungicide in a linear contamination gradient.

The present study examines the ability of juvenile Danio rerio to avoid pyrimethanil-contaminated water. An avoidance assay system was used with a contamination gradient formed by seven compartments, through which the fish could move and choose the preferred compartment(s). Additionally, the influence of fish movements in promoting the mixing between compartments and thus disruption of the gradient over time was also examined by testing sodium chloride (NaCl) at sublethal concentrations.

[Hyphessobrycon taphorni and H. eschwartzae (Teleostei: Characidae) two new species of fish in the basin of Madre de Dios river, Peru].

Hyphessobrycon with 129 valid species, is a genus of fish that has a great diversity of species in the Neotropical ichthyofauna, reaches its greatest diversity in the Amazon basin with about 70% of these species, is highly desired by hobbyists because of their beauty and color, and are still meeting new species. We analyzed specimens from the Departamento de Ictiología, Museo de Historia Natural de la Universidad Mayor de San Marcos, Lima, Perú (MUSM); and measurements of the specimens were taken point to point with digital calipers. Observations of bone and cartilage structures were made on cleared and stained (C&S) samples.

Spatio-temporal clusters of incident human brucellosis cases in Ecuador.

This study aimed to determine whether variations in the incidence of reported cases of human brucellosis in Ecuador were clustered in space and time. In addition, the effects of cattle and small ruminant population density and other socio-economic factors on the incidence were investigated. Significant space-time clusters were found in the northern and southern highlands and parts of Ecuadorian Amazonia.

3-Benzyl-2-(4-fluorophenyl)-1,3-thiazolidin-4-one.

The title compound, C(16)H(14)FNOS, crystallizes with Z' = 2 in the space group P2(1)/c. In one of the two independent molecules, the heterocyclic ring is effectively planar, but in the other molecule this ring adopts an envelope conformation. The molecules are weakly linked by two C-H···O hydrogen bonds to form C(2)(2)(14) chains.

[Dung beetles (Coleoptera: Scarabaeinae) of the northwestern slope of the Sierra Nevada of Santa Marta, Colombia].

The community structure of dung beetles in the middle and lower river basin of the Gaira river, Sierra Nevada de Santa Marta, Colombia, is described. Four sites were selected along an altitudinal gradient of 50-940 m for sampling from June to October, 2004. Dung beetles were captured using modified pitfall traps and manual recollections.

Epilepsy in the developing world.

Developing countries (DCs) and developed countries have geographic, economic, and social differences. The prevalence and incidence of epilepsy are higher in DCs than in developed countries. However, within DCs, given the high incidence of epilepsy, the prevalence is relatively low, which may be due to high mortality for people with epilepsy (PWE).

[Forestry Law and the conservation of natural areas and wildlife].

The Forest Law of Ecuador consists of 107 articles, whereas its regulations contain 269 articles. They are related to forestry resources, forestry patrimony protection, forests and vegetation, forest production and benefits, the control and mobilization of the forestry resources, research and capacitation, and the forestry industry protection; to natural areas, wild flora and fauna, their patrimony, conservation, and economic support; and to the violation of the law and its judgment.
