La salud es un bien especialmente querido por el ser humano. Su privación la causa desasosiego, sufrimiento, ansiedad y, en buena medida, infelicidad. Por ello, no es de extrañar que, en los albores del siglo XXI, las enfermedades de posible propagación masiva sigan preocupando produndamente al hombre, que vuelve entonces sus ojos a los hombre de ciencia pidiéndoles un remedio, una vacuna que evite los riesgos y las consecuencias de una pandemia.La gripe aviaria, al decir de los expertos, no debe, por ahora, preocuparnos; pero sí ocuparnos. Esta publicación pone en manos de la comunidad científica y académica una pionera contribución al conocimiento y estudio de una enfermedad que todos esperamos y deseamos que no traspase las fonteras de la especie entre la que ahora se propaga.
This Yearbook aims to contribute to a greater awareness of the functions and activities of the organs of the Inter-American system for the protection of human rights. The Yearbook is partly published as an English-Spanish bilingual edition. Two volume set.
The growing concern for human wellbeing has generated an increase in the demand for polyphenols, secondary plant metabolites that exhibit different bioactive properties. This increasing demand is mainly due to the current applications in the food industry where polyphenols are considered essential for human health and nutrition. Advances in Technologies for Producing Food-relevant Polyphenols provides researchers, scientists, engineers, and professionals involved in the food industry with the latest methodologies and equipment useful to extract, isolate, purify, and analyze polyphenols from different available sources, such as herbs, flora, vegetables, fruits, and agro-industrial wastes. Technologies currently used to add polyphenols to diverse food matrices are also included. This book serves a reference to design and scale-up processes to obtain polyphenols from different plant sources and to produce polyphenol-rich foods with bioactive properties (e.g. antioxidant, antibacterial, antiviral, anticancer properties) of interest for human health and wellbeing.
Phenolic compounds are an extremely diverse class of ubiquitous secondary metabolites produced by a variety of organisms playing different biological roles. They have numerous types of demonstrated bioactivities, including antioxidant, antimicrobial, anti-inflammatory, antitumoral, immunomodulator, neuroprotective, cardioprotective, and antidiabetic activities. Marine organisms produce a vast collection of unique phenolic structures, some of them not found in terrestrial habitats. Progress in different aspects is rapidly advancing, and this Special Issue will provide updated information and recent studies on marine phenolics. Specially, this issue is focused on their chemical characterization, elucidation of their structures, evaluation of their biological properties and mechanisms of action, efficient extraction and purification technologies, development of value-added applications, as well as formulation of novel products.

The marriage of philosophy and fiction in the first third of Spain's twentieth century was a fertile one. It produced some truly notable offspring -- novels that cross genre boundaries to find innovative forms, and treatises that fuse literature and philosophy in new ways. In her illuminating interdisciplinary study of Spanish fiction of the "Silver Age," Roberta Johnson places this important body of Spanish literature in context through a synthesis of social, literary, and philosophical history. Her examination of the work of Miguel de Unamuno, Pio Baroja, Azorin, Ramon Perez de Ayala, Juan Ramon Jimenez, Gabriel Miro, Pedro Salinas, Rosa Chacel, and Benjamin Jarnes brings to light philosop...
