Peptides modulate many processes of human physiology targeting ion channels, protein receptors, or enzymes. They represent valuable starting points for the development of new biologics against communicable and non-commun...

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...

The temporal dynamics in biological systems displays a wide range of behaviors, from periodic oscillations, as in rhythms, bursts, long-range (fractal) correlations, chaotic dynamics up to brown and white noise. Herein, ...

Computer-aided drug discovery and design involve the use of information technologies to identify and develop, on a rational ground, chemical compounds that align a set of desired physicochemical and biological properties...

In this survey article we present some of Janusz Czelakowski’s most influential contributions to the theory of quasivarieties. The material includes his work on: definability of principal congruences, characterizations...

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...

In the context of global warming, droughts are increasingly threatening our societies. They last for months or even years, affecting wide areas and large numbers of people, with single drought events sometimes causing ec...

The function of the HPA axis is subject to regulation by many factors, which achieve relevance under normal and pathological conditions. In the case of aging, this period of life is associated with disturbances of the HP...

Ex vivo-generated antigen-loaded dendritic cells (DC) have been shown to be immunogenic in patients with cancer. Loading DC with autologous whole tumor antigens is a strategy to arm DC against tumor without human leukocy...

As a global conflict, the First World War was fought in and from different world locations and at different levels, including through the realms of symbolism. To mobilize human and material resources, justify the war and...

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...

The pattern of somatic growth reflects the variable allocation of energy and materials throughout ontogeny, with direct impact on an individual’s fitness, and is therefore expected to be adaptive with regard to the dif...

E-learning systems present to students learning material carefully prepared and organized by teachers to meet some course goals. However, further relevant information that can help students to complete their learning pro...

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...

HD 195592 is an O-type supergiant star, known as a well-established runaway. Recently, a Fermi γ-ray source (2FGL J2030.7+4417) with a position compatible with that of HD 195592 has been reported. Our goal is to explore...

Particle filters have been widely used as a solution to the Bayesian filtering problem, propagating in time a Monte Carlo (MC) approximation of the a posteriori filtering measure. In many situations, the exact statistics...

Capybaras (Hydrochoerus hydrochaeris) have been used in Argentina since pre-Columbian times as a source of hide, meat, and fat. Hide is the most valuable capybara by-product and, at present, represents the major hunting ...

The armoured harvestman family Triaenonychidae (Opiliones: Laniatores) has a predominantly temperate Gondwanan distribution, with representatives in southern South America, South Africa, Madagascar, Australia, New Zealan...

The presence of fluids in the pore space of rocks causes wave attenuation and dispersion by the mechanism broadly known as wave-induced fluid flow (WIFF). WIFF occurs as a seismic wave creates pressure gradients within t...

Bioethanol is one of the most important renewable fuels and it is classified into four different generations (G) based on the feedstocks used for their production: edible food crops such as rice, corn, sugarcane, wheat, ...

Cloud computing is a business paradigm, where cloud providers offer resources (e.g., storage, computing, network) and cloud consumers use them after accepting a specific service level agreement. Cloud requirements can ra...

This book focuses on the various invasive and non-invasive techniques which can be used for the characterization of starch macromolecules along with, the various types of physical, chemical, and enzymatic modifications o...
