This chapter turns to the global concern about aging societies, and the so-called epidemic of aging. It argues that a public health approach to aging and Alzheimer's will have a much greater effect in reducing the incidence of Alzheimer disease (AD) worldwide than will the technologically oriented molecular approach currently being heralded as a paradigm shift. Should such an approach be effective, and there is little evidence to date to be optimistic that this will be the case, the extent of investment in advanced medical facilities and highly trained expertise required to put it in place is not realistic beyond wealthy segments of the world, especially given the global economy of the present and the increasing gaps between rich and poor.Less

This concluding chapter presents emerging knowledge in both epigenetics and epidemiology, suggesting that forms of prevention that take a public health approach, including lifestyle changes, reduced exposure to toxins, reductions in poverty, increased community support, and other variables, is likely to reduce the prevalence of dementia worldwide to a much greater extent than would an approach confined to expensive molecular micro-medical management of segments of those populations deemed to be at risk that happen to be located in wealthier countries. Furthermore, a molecular approach to Alzheimer disease prevention requires healthy individuals, some as young as 18 years of age, to become research subjects on whom repeated tests will be carried out.Less

This chapter studies a number of important aspects related to the plasticity and complexity of biological systems and their links. The relationship between the topological organization and dynamics of chromatin and chromosome, the regulatory proteins networks, and the mechanisms of genetic expression are also investigated further in the following sections. The ultimate goal is to show the need for new scientific and epistemological approaches to the life sciences. In this respect, it is argued that, in the near future, research in biology must shift drastically from a genetic and molecular approach to an epigenetic and organismal approach, particularly by studying the network of interactions among gene pathways, the formation and dynamics of chromatin structures, and how environmental conditions may affect the response and evolution of cells and living systems.Less

The Cactaceae family, with about 1,600 species, is cultivated worldwide for fruits, forage, fodder, and even as a vegetable. Cacti are recognized for their attractive flowers, special stem shapes, and ability to tolerate drought. Because of their efficient use of water and other adaptations, biological and agronomic interest in cacti has soared. These plants also have much to teach us about biodiversity and conservation. This book, compiled by a well-known cactus biologist, includes chapters by 35 contributors from around the world on topics ranging from evolution to biotechnology. It compiles information on cactus biology, ecology, and uses in one place. The first half of the book provides an overview of cactus biology and morphology, and discusses the environmental and conservation issues that affect the plants, including a discussion of the evolution of the family which pays particular attention to new genetic and molecular approaches. The second half of the book focuses on the practical concerns of cultivating cacti, such as pest control and diseases, horticultural and forage applications, and techniques for agronomy. Other chapters cover the different markets for cacti and products that are made from them.Less

The concept of the cryosphere being a biome has only recently gained acceptance. The study of the ecology of these extreme environments is relatively new and demands novel approaches. This chapter discusses priority sites for future research in Antarctica and the Arctic, and the application of remote sensing, sensor technology, and molecular approaches to their investigation. It also outlines the process of developing mathematical models to characterise processes in cryospheric environments.Less
