Preprint
Changes in the food system are necessary for attaining the Sustainable Development Goals. A shift in current dietary patterns, especially in developed countries, is one of the most effective measures to achieve a sustainable and fair food system. In this viewpoint, we i) contend why, alongside structural changes to the food production and distribut...

The 2015–2020 Dietary Guidelines for Americans (DGA) was issued in early 2016. It remains untested if adherence to these guidelines could reduce mortality risk. Using a modified version of the 2015 Dietary Guidelines for American Index (2015 DGAI), we investigated if adherence to the new DGA is associated with mortality in a Spanish (the Seguimient...

Objective How food is produced and consumed has consequences for ecosystems, such as resource use and greenhouse gas (GHG) emission among others. The Mediterranean diet (MedDiet) was proposed as a sustainable dietary model, due to its nutritional, environmental, economic and sociocultural dimensions. However, further evidence is needed. Thus, our o...

The steroid hormone ecdysone is a central regulator of insect development. In this report we show that CTCF expression in the prothoracic gland is required for full transcriptional activation of the Halloween genes spookier, shadow and noppera-bo, which encode ecdysone biosynthetic enzymes, and for proper timing of ecdysone-responsive gene expressi...

Insulators are DNA-protein complexes that play a central role in chromatin organization and regulation of gene expression. In Drosophila different proteins, dCTCF, Su(Hw), and BEAF bind to specific subsets of insulators most of them having in common CP190. It has been shown that there are a number of CP190-binding sites that are not shared with any...
