In the 1970s, flame retardants began to be added to synthetic materials to meet strict flammability standards. Over the years, diverse flame retardants have been manufactured and used in various products. Some flame retardants have migrated out of the products, and this has led to widespread human exposure and environmental contamination. There also is mounting evidence that many flame retardants are associated with adverse human health effects. As a result, some flame retardants have been banned, restricted, or voluntarily phased out of production and use. This publication develops a scientifically based scoping plan to assess additive, nonpolymeric organohalogen flame retardants as a class for potential chronic health hazards under the Federal Hazardous Substances Act, including cancer, birth defects, and gene mutations.

Annelids (the segmented worms) exist in a remarkably diverse range of mostly marine but also freshwater and terrestrial habitats, varying greatly in size and form. This text provides. This text begins with an introduction to the phylum and an outline of annelid taxonomy. The book describes their collection and the methods to ensure their optimal preservation, and provides an overview of anatomy with its relevant terminology. It includes the latest molecular phylogenomic evidence and is organised based on a new, robust phylogenetic hypothesis. It looks at groups which include Clitellata (comprising more than a third of total annelid diversity), Sipuncula, and Thalassematidae (formerly Echiura). It reflects the enormous amount of research on these organisms that has burgeoned since the millennium, principally due to their use as model organisms to address wider and more general evolutionary and ecological questions.

In the last decade, there has been substantial research dedicated towards prospecting physiochemical, nutritional and health properties of novel protein sources. In addition to being driven by predictions of increased population and lack of a parallel increase in traditional protein sources, main drivers for the rise in novel proteins/ novel foods research activities is linked to significant changes in young consumers’ attitudes toward red meat consumption and their interest in new alternative protein products. Alternative Proteins: Safety and Food Security Considerations presents up-to-date information on alternative proteins from non-meat sources and examines their nutritional and functional roles as food sources and ingredients. Emphasis is placed on the safety of these novel proteins and an evaluation of their potential contribution to food security. Motivations for novel proteins and restrictions for their use are also discussed. Key Features: Explains potential improvements to alternative proteins through the employment of novel processing techniques. Contains the first review on keratin as an alternative protein source. Explores first comprehensive evaluation of the religious aspects of novel proteins. Describes methods for the detection and evaluation of health hazards. Discusses guidelines, regulatory issues and recommendations for food safety Additionally, this book covers fundamental and recent developments in the production of alternative proteins, and examines safety and consumer acceptability wherever information is available. The sources and processing options for alternative proteins and their impact on final product characteristics are also covered. A collective contribution from international researchers who are active in their field of research and have made significant contributions to the the food sciences, this book is beneficial to any researcher interested in the the food science and safety of alternative proteins.

Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Although the majority of consumed insects are gathered in forest habitats, mass-rearing systems are being developed in many countries. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. It shows the many traditional and potential new uses of insects for direct human consumption and the opportunities for and constraints to farming them for food and feed. It examines the body of research on issues such as insect nutrition and food safety, the use of insects as animal feed, and the processing and preservation of insects and their products. It highlights the need to develop a regulatory framework to govern the use of insects for food security. And it presents case studies and examples from around the world. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. To fully realise this potential, much work needs to be done by a wide range of stakeholders. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.

A consummate classic with a fresh approach to pediatric dermatology Children ́s skin is different. Maturation affects the epidermal barrier, the cutaneous microbiome, adnexal structures, vasculature, and transcutaneous absorption of drugs. The immature skin is more susceptible to pathogens and environmental disruption. Many genetic disorders are either present at birth or manifest early in childhood. Skin diseases thus present differently in children than in adults. Pediatric dermatology has seen significant advances over the last decade, particularly in the field of molecular genetics research, which has furthered our understanding of the pathogenesis of many skin diseases and the development of new approaches to treatment. This fourth edition of the Harper classic provides state-of-the-art information on all aspects of skin disease in children. It covers the diagnosis and treatment of all conditions - both common and rare - with a consistently evidence-based approach. Existing content has been refreshed and fully updated to reflect emerging thinking and to incorporate the latest in research and clinical data - especially at the genetic level. This new fourth edition includes: Greater focus on the genetics behind skin disease, including new genes/genodermatoses, progress in genetic analysis, and stem cell transplants Increased coverage of lasers and other technologies used to treat skin disease More summary tables, learning points, tables of differential diagnosis, and clinical algorithms for diagnosis and management Additional online features, including patient information links and multiple choice questions Harper's Textbook of Pediatric Dermatology delivers crucial clinical insights and up-to-date research information that spans the breadth of the field. As the most comprehensive reference book on this subject available, this revised fourth edition will support and guide the daily practice of both dermatologists and pediatricians across the world.
