Using the example of our own work about astronomies in the Argentinian Chaco, we show the fruitfulness of a regional approach to ethnoastronomical studies. Our interest is to highlight the relevance of thinking the astro...

Purple carrots (Daucus carota ssp. sativus var. atrorubens Alef.) accumulate anthocyanins in their roots, petioles and other plant parts. These flavonoid pigments represent an excellent dietary source of antioxidant and ...

Among the South American Arid Diagonal (SAAD), the Argentine Arid Diagonal (AAD) constitutes an area with low precipitations (less than 500 mm) and extends from the north of the country (on the border with Bolivia), to P...

Stomatal pore regulation is a key process for carbon and water homeostasis of terrestrial plants. The pore size is modulated through changes in the guard cell volume, driven by variations in the osmotic potential of the ...

This work presents the initial steps for the development of a serious game aimed at training users of upper limb prosthesis. In this initial phase, a virtual environment consisting of a soccer stadium was developed using...

Dehydrated fruits are prone to discoloration during storage. Many natural pigments are unstable in dried fruits, and brown pigments can be formed. The rate of physical and chemical changes in dried vegetables and food mo...

Beyond the unique sound of howler monkey vocalizations, their vigorous loud calling displays are perplexing given the otherwise sedentary lifestyle of these primates. Here we provide potential explanations for this energ...

Hybridization, or the process by which individuals from genetically distinct populations (e.g., species, subspecies) mate and produce at least some offspring, is of great relevance to understanding the basis of reproduct...

Co-Immunoprecitation is a powerful and commonly used method to identify protein-protein interactions in a physiological context. Here, we report a Co-Immunoprecitation Co-IP protocol that was adapted and optimized for th...

The Mapuche communities of the Argentinean extra-Andean Patagonia overcome extreme living conditions by applying subsistence strategy based on the utilization of different ethno-ecological units corresponding with differ...

Hunting and gathering remained the main mode of subsistence of humanity for hundreds of thousands of years, beginning some 1.8 million years ago, and until the Neolithic Revolution (some 10,000 years ago), when agricultu...

Intracellular levels of cyclic nucleotide second messengers are regulated predominantly by a large superfamily of phosphodiesterases (PDEs). Most of the different PDE variants play specific physiological functions; in fa...

Population coding is the quantitative study of which algorithms or representations are used by the brain to combine together and evaluate the messages carried by different neurons. Here, we review an information-theory b...

Heteroduplex-based genotyping methods have proven to be technologically effective and economically effi cient for low- to medium-range throughput single-nucleotide polymorphism (SNP) determination. In this chapter we des...

Layer-by-layer (LbL) self-assembly microencapsulation is a promising method to protect and deliver probiotics, although its implementation has mostly been confined to the lab scale. This study develops a scalable method ...

Multi-target agents have attracted great attention in the last 15 years, as they are expected to provide more efficacious and safer therapeutic solutions, less prone to drug resistance phenomena. They thus seem particula...

Refractories are defined as "non-metallic materials having those chemical and physical properties that make them applicable: for structures, or as components of systems, that are exposed to environments above 1,000 °F (...
