Phenotypic Variation in Populations: Relevance to Risk Assessment
ISBN: 9781468454628 / Angielski / Miękka / 2013 / 305 str. Termin realizacji zamówienia: ok. 20 dni roboczych. The human race has enormous he terogenei ty, founded on genetic and environmental sources. Variability, therefore, is a vital dimension in any consideration of human risk assessment. In the estimation of risks, current methods of extrapolation based upon converting the response of a median man are inadequate, as they ignore phenotypic variation and there- fore, susceptible subgroups. There is a growing literature defining the extent of human variation in normal populations; thus, the normal young adult population may have 10-20% known hyperreactors. How far can we ignore human variability in...

Evolution of Longevity in Animals: A Comparative Approach
ISBN: 9781461290773 / Angielski / Miękka / 2011 / 354 str. Termin realizacji zamówienia: ok. 20 dni roboczych. The analysis of intra-group correlations between LS and BW at representative intervals yields no consistent support for the hypothesis that lower BW is associated with longer LS. Indeed, among male Wistar rats and C57BL/6J and A/J mice followed since weaning on AL diets, the data suggested that relatively higher BW across the adult LS was generally associated with longer life. Even when the diet was restricted by EOD or RES regimens, this pattern of positive correlations between LS and BW persisted for the C57BL/6J and A/J strains when relative ages were analyzed. However, when BW at absolute...

Biotechnology and the Human Genome: Innovations and Impact
ISBN: 9781468455496 / Angielski / Miękka / 2012 / 175 str. Termin realizacji zamówienia: ok. 20 dni roboczych. This book is based on the proceedings of the Science Writers Workshop on "Biotechnology and the Human Genome: Innovations and Impacts" held at the Brookhaven National Laboratory on September 14-16, 1987. The aim of this workshop which was sponsored by the Office of Health and Environmental Research of the Department of Energy (DOE) was to provide a forum in which science writers, reporters and other interested individuals could gain a firsthand knowledge about the scope and direction of the human genome initi- ative and its supportive technologies. The speakers were leaders working in...

Primary Productivity and Biogeochemical Cycles in the Sea
ISBN: 9781489907646 / Angielski / Miękka / 2013 / 550 str. Termin realizacji zamówienia: ok. 20 dni roboczych. Biological processes in the oceans play a crucial role in regulating the fluxes of many important elements such as carbon, nitrogen, sulfur, oxygen, phosphorus, and silicon. As we come to the end of the 20th century, oceanographers have increasingly focussed on how these elements are cycled within the ocean, the interdependencies of these cycles, and the effect of the cycle on the composition of the earth's atmosphere and climate. Many techniques and tools have been developed or adapted over the past decade to help in this effort. These include satellite sensors of upper ocean phytoplankton...

Molecular Biology of Aging
ISBN: 9781489922205 / Angielski / Miękka / 2013 / 482 str. Termin realizacji zamówienia: ok. 20 dni roboczych. It is delightful but humbling to find my face at the start of these Proceedings--there are innumerable other faces which could equally weIl stand there, from among the band who have fore- gathered at every gerontology conference since the subject was launched in its present form; but I deeply appreciate being there. Gerontology d. id not grow by accident. Its present standing is the fruit of careful planning, undertaken by European and American scientists back in the 1950's. In those days it was still a "fringe" science, and the conspirators had much the standing of the 1920's Interplanetary...
