Sommario/riassunto |
|
Spanish is a pluricentric language, meaning that it has several centers of prestige (e.g., San Juan, Buenos Aires, Mexico City, Lima). Moreover, Spanish, like all languages, evinces sociolinguistic variation, in that levels of formality are expressed through the use of different structures. Given this variety, students of Spanish will inevitably come |

|
|
|
|
|
|
|
|
|
|
|
|
into contact with variation Spanish. This variation in Spanish adds layers of complexity to the learning and instruction of the Spanish language; therefore, a linguistic understanding of variation is crucial for our students to achieve communicative competence. This unique work, which provides an overview of the most important linguistic aspects of Spanish within a context that recognizes variation, assumes no prior linguistic knowledge and is appropriate as a valuable resource manual for teachers and learners of Spanish alike. |

Sommario/riassunto |
|
Natural products are bioactive compounds synthesized by terrestrial and marine plants, microorganisms and animals, whose main objective is to prevent them from attacks by predators and/or pathogens. Traditionally since ancient times, different cultures have used these compounds for the prevention and treatment of various human diseases. During the last few years, it has been reported that most of these phytochemicals possess a variety of interesting and significant biological properties, such as analgesic, antiallodynic, antidiabetic, antioxidant, antiparasitic, antimicrobial, antiviral, antiatherogenic, anti-inflammatory, antiproliferative, antitumor and normal growth stimulants, as well as significant cardioprotective and neuroprotective activity. This thematic book aims to collect and disseminate some of the most significant and recent contributions of the use of the natural |

|
|
|
|
|
|
compounds called phytochemicals, as well as some of their chemical derivatives, for the prevention and treatment of cancer and other accompanying diseases. On the other hand, in recent years, the synthesis of numerous chemical derivatives of these natural compounds has also intensified, with the aim of enhancing their bioactive capacities. Among all these bioactivities, special attention has been paid to its antitumor capacity through the potential modulation of cancer initiation and growth, cell differentiation, apoptosis and autophagy, angiogenesis, and metastatic dissemination. In addition, a considerable number of studies have linked their anticancer effects to their anti-inflammatory and antioxidant activities. |
