The International Space Station is a closed and complex environment, so some contamination of its internal atmosphere and water system is expected. To protect space crews from contaminants in potable and hygiene water, the National Aeronautics and Space Administration (NASA) requested that the National Research Council (NRC) provide guidance on how to develop water exposure guidelines and review NASA's development of the exposure guidelines for specific chemicals. NASA selects water contaminants for which spacecraft water exposure guidelines (SWEGs) will be established; this involves identifying toxicity effects relevant to astronauts and calculating exposure concentrations on the basis of t...
The Permanent Commission and International Association on Occupational Health (PCIAOH) established in 1969 a Subcommittee on the Toxicology of Metals under the chairmanship of Lars Friberg. This committee, which later was named the Scientific Committee on the Toxicology of Metals, has organized a number of previous meetings that have led to publications in three major areas of metal toxicology: a preliminary meeting in Slanchev Bryag, Bulgaria in- 1971, followed by a meeting in 1972 in Buenos Aires, Argentina which produced two reports (Dukes and Friberg, 1971; Task Group on Metal Accumulation, 1973), that discussed the metabolism of metals with special reference to absorption, excretion and...
Protecting Infants through Human Milk: Advancing the Scientific Evidence provides a forum in which basic scientists, clinicians, epidemiologists, and policy makers exchange the latest findings regarding the effects of human milk and breastfeeding on infant and maternal health, thereby fostering new and promising collaborations. This volume also integrates data from animal and in vitro laboratory studies with clinical and population studies to examine human milk production and composition, the mechanisms of infant protection and/or risk from human milk feeding, and proposed interventions related to infant feeding practices. Additionally, it stimulates critical evaluation of, and advances in, the scientific evidence base and research methods, and identifies the research priorities in various areas.

This reference compiles a broad spectrum of perspectives from specialists in academic, governmental, and industrial research settings to demonstrate the influence of biochemistry and biotechnological applications on functional food developments. Focusing on topics not covered in depth in other texts on the subject, the book analyzes the nutritional and physiological benefits of functional foods, the effect and development of active ingredients in functional foods, and consumer and regulatory issues that will influence biotechnological advancements in the food industry. It also Illustrates the expanding role of functional foods and nutraceuticals in the promotion of human health.
Biochemical indicators of dietary nutrient intake are called biomarkers. They are used in clinical settings to assess deficiency or excess of nutrients like iron, iodine, vitamin C and D. In nutritional epidemiology biomarkers are used to classify subjects according to their nutrient intake from foods and relate it to a disease. Biomarkers can be classified into poor, intermediate and good according to several criteria. Many factors influence the relationship between nutrient intake and tissue concentration like homeostasis, metabolism, age, gender and nutrient interactions. An important factor to be taken into account is also whether the biomarker reflects short or long term intake. By the ...
The International Workshop on human lactation dedicated specifically to the topic of Maternal and Environmental Effects on Lactation repre sents the recent progress of research in human lactation. Only four years ago it was clear that we do not yet have sensitive research techniques specifically adapted to the study of human milk. This need was addressed by an NIH convened workshop in 1982, the concensus being that appropriate methods have to be developed for the study of the composition of human milk. The progress in the development of these techniques was the subject of the second workshop on human lactation, dedicated specifically to "Milk Components and Methodologies. " The workshop was ...
This informative treatise offers a concise collection of existing, expert data summarizing the composition of milk. The Handbook of Milk Composition summarizes current information on all aspects of human and bovine milk, including: sampling, storage, composition, as well as specific chapters on major and minor components such as protein, carbohydrates, lipids, electrolytes, minerals, vitamins and hormones. The book also features comprehensive coverage of compartmentation, host-defense components, factors affecting composition, composition of commercial formulas, and contaminants.* Reliable data on the composition of human and bovine milks.* Discusses the many factors affecting composition.* Composition tables make up 25-30% of the total book.* Problems concerning sampling and analysis are described.* Should appeal equally to industry and academia.* Also of interest to developing countries in need of information on infant nutrition and agricultural development
In recent years there have been great advances in the development of new nanomaterials. To facilitate the progress of new materials it is essential to understand the underlying principles at the nanoscale. Nanoscopic Materials provides an accessible overview of the physico-chemical and physical principles of nanomaterials including electronic structure, magnetic properties, thermodynamics of size dependence and phase transitions and dynamics of clusters and two-dimensional systems. This new edition has been fully revised and updated to reflect recent developments in new nanomaterials including graphene and core–shell structures, properties of nano-structured and intelligent surfaces as well as applications in catalysis and energy. Additional chapters cover the development of nucleation and crystal shape engineering; self-assembly and biomimetics for fabricating nanostructures. With helpful illustrations and summaries of key points in every chapter, this advanced textbook is ideal for graduate students of chemistry and materials science and researchers new to the field of nanoscience and nanotechnology.
The major emphasis in this book is a compilation and definition of what is known about components of human milk, including glycoconjugates, that inhibit common pathogens of the infant. Also discussed are other bioactive constituents whose relevant biological roles are also beginning to be defined. Hormonal and cytokine activity, immunomodulating and autoinflammatory agents, xenobiotics, and conditionally essential nutrients in milk could have roles in the protection of the infant, but may also participate in digestive processes, maternal-infant communication, maturation of the gut, central nervous system, and other components of infant growth and development. Like the protective activities, these are discussed in terms of their presence in milk, structures, potential functions, and structure/function relationship. Components whose role is nutritional support during early development of the infant are also included.
