The word melanin refers to dark natural pigments produced by the oxidative degradation of tyrosine, catalyzed by tyrosinase, and polymerized into insoluble granular substance. The main function of melanin is to protect from harmful agents, primarily UV radiation, but also from oxidation, heavy metals, etc. In this volume, chapters deal with production of melanin in human oral mucosa (Liviu et al.), the regulation of melanin action (Cecile et al.), production and potential technological application of fungal melanins (Pombiero-Sponchiado et al.) and an innovative method for measuring melanin in various samples (Zdybel et al.). In conclusion, this volume presents various biological and industrial aspects of melanin production, uses and analysis.

Honey Analysis - New Advances and Challenges discusses advances in honey research. Topics include the physicochemical characteristics of honey from stingless bees, the therapeutic properties of honey, melissopalynological analysis as an indicator of the botanical and geographical origin of honey, and methods for authenticating honey. Written by experts in the field, this book provides readers with an indispensable source of information, assisting them in future investigations of honey and beekeeping.
This is a compilation of bibliographic (historical and descriptive) information for the minerals first described from Brazil; it includes both valid and invalid, discredited species, unnamed, unidentified, problematic minerals, and so on. This work brings together as much data as possible concerning type mineral species. It will save future researchers a lot of work because it contains data from many publications that are difficult to obtain.
This volume in the series deals with the major Medicinal and Aromatic Plants MAPs of South America, providing information on major aspects of this specific group of plants on that continent (botany, traditional usage, chemistry, production/collection practices, trade and utilization). Brazil, in particular, offers an immense amount of biodiversity, including plants with great pharmacological interest and medicinal importance. The Amazon Basin, in northern Brazil has a highly diverse biota and still harbours a variety of unknown and unstudied plant species for medicinal values. Contributions are from internationally recognized professionals, specialists of the Medicinal and Aromatic Plant domain and have been invited mostly from the members of the International Society for Horticultural Science and International Council for Medicinal and Aromatic Plants.
Every three years, the International Society for Arterial Chemoreception (ISAC) arranges a Meeting to bring together all of the major International research groups investigating the general topic of oxygen sensing in health and disease, with a prime focus upon systemic level hypoxia and carotid body function. This volume summarises the proceedings of the XIXth meeting of the Society, held in Leeds, UK during the summer of 2014. As such this volume represents a unique collection of state of the art reviews and original, brief research articles covering all aspects of oxygen sensing, ranging from the molecular mechanisms of chemotransduction in oxygen sensing cells such as the carotid body type I cells, to the adverse, reflex cardiovascular outcomes arising from carotid body dysfunction as seen, for example, in heart failure or obstructive sleep apnoea. This volume will be of tremendous interest to basic scientists with an interest in the cellular and molecular biology of oxygen sensing and integrative, whole organism physiologists as well as physicians studying or treating the clinical cardiovascular consequences of carotid body dysfunction.
This book is a compendium of knowledge about nanomaterials and strategies for bioremediation over hazardous environmental pollutants. The book is divided into 2 sections. Section 1 deals with the polluted environment, where it explains that soil is in serious danger and highlights the primary hazardous pollutants. Besides, this section covers algae, autochthonous, introduced, or genetically modified organisms that are used to degrade hazardous contaminants. In Section 2, Bio- and Nanoremediation are shown through synthesis, green synthesis and molecular farming, and their applications or impacts. Moreover, this discusses bio- and nano-remediation, working together for better performance, organisms, and nanomaterials for environmental remediation.
