[Body adiposity and abdominal muscle resistance in young people with Down syndrome].

Objective: to verify the relationship between abdominal muscle endurance and the level of body fat, measured through the waist-to-height ratio, in young people with Down syndrome (DS).

Subject And Method: A comparative descriptive study was carried out in 115 young people with DS (n = 65 men and n = 50 women) aged between 10 and 18 years, from the Maule Region. Age, weight, height, and waist circumference were evaluated.

Stitching together a nm thick peptide-based semiconductor sheet using UV light.

Langmuir monolayer allows for a two-dimensional nano-scale organization of amphiphilic molecules. We have adapted this technique to measure lateral and transverse conductivity in confined peptide nanosheets for the first time. We reported that two retro-isomers amphipathic peptides form stable monolayers showing a semiconductor-like behavior.
