This will be both expensive and time-consuming; however, at least in selected cases (e.g., cases of aging and dementia with brain atrophy), such an interaction will be essential. More speculative will be the use of MRI to further constrain PET data by defining gray-white matter differences.

  • Most available literature on cockroaches deals with domestic pests and the half dozen or so other species that are easily and commonly kept in laboratories and museums. It reflects the extensive efforts undertaken to find chinks in the armor of problematic cockroaches, and the fact that certain species are ideal for physiological and behavioral investigations under controlled conditions. These studies have been summarized in some excellent books, including those by Guthrie and Tindall (1968), Cornwell (1968),Huber et al. (1990), Bell and Adiyodi (1982a), and Rust et al. (1995).

  • Biometrics uses methods for unique recognition of humans based upon one or more intrinsic physical or behavioral traits. In computer science, particularly, biometrics is used as a form of identity access management and access control. It is also used to identify individuals in groups that are under surveillance. The key objective of the book is to provide comprehensive reference and text on human authentication and people identity verification from physiological, behavioural and other points of view (medical biometrics).

  • Marine birds are equally at home on land, in the air, and in the water. While many organisms can go from land to water (amphibians, some reptiles, some insects), others generally live in only one medium during their lives. Marine birds switch from one to the other, often daily. Such flexibility requires unique physiological and morphological adaptations to the environment, a medium that has also exerted selective forces on the behavior, ecology, and demography of these birds.

  • Although metabolites and energy balance have long been known to play roles in the regulation of food intake, the potential role of fatty acid metabolism in this process has been considered only recently. Fatty acid synthase (FAS) catalyzes the condensation of acetyl-CoA and malonyl-CoA to generate long-chain fatty acids in the cytoplasm, while the breakdown of fatty acids (h-oxidation) occurs in mitochondria and is regulated by carnitine palmitoyltransferase-1 (CPT-1), the rate-limiting step for the entry of fatty acids into the mitochondria....

  • Cell biology studies the structural and physiological properties of cells, including their behaviors, interactions, and environment. This is done on both the microscopic and molecular levels, for single-celled organisms such as bacteria as well as the specialized cells in multicellular organisms such as humans. Understanding the structure and function of cells is fundamental to all of the biological sciences. The similarities and differences between cell types are particularly relevant to molecular biology....

  • T he science of human nutrition and its applications to health promotion continue to gain momentum. In the relatively short time since the release of the first edition of this Encyclopedia, a few landmark discoveries have had a dramatic multiplying effect over nutrition science: the mapping of the human genome, the links between molecular bioenergetics and lifespan, the influence of nutrients on viral mutation, to name a few.

  • To represent the specific behaviors of this reflection, a schematic model was sought that simultaneously covered health promotion and the Health Policy for the Elderly, with a view to adopting actions for greater awareness, resulting in attitudes of empowerment and suggestions for gerontogeriatric nursing actions. Nola Pender’s Health Promotion Model(10) was used. Through a chart, it manages to represent the behaviors that can lead to health promotion. Nola Pender’s Model was developed in the United States in the 1980s, but was little explored in Brazil.

  • Virtually every organism serves as the host for a complement of parasites. Parasitism is so common that it is rare to find classes of animals without members that have adopted a parasitic mode of living. Evidence gained from various archeological studies indicates that parasitic diseases existed in prehistoric human populations. Since there is no evidence to suggest that our long and intimate association with parasites will ever end, it seems reasonable to propose that the study of human parasites warrants some consideration.

  • In order to gain an overview of our planet’s animal diversity, we humans have developed a scientific classification system, in which every life form holds an allotted place. Classification occurs according to universally applicable, internationally recognized rules established by the Swedish naturalist Carolus Linnaeus in his famous work Systema Naturae, published in 1735. Since then, all known living creatures have been divided into categories according to their different physiological and behavioral characteristics....

  • Plants are a distinct kingdom of organisms that possess unique properties of reproduction, development, physiology, and adaptation. Plant diversity refers to the variety of plants that exist on the Earth. Plants, in order to survive, have to compete with other plants and organisms in an ecosystem. Over time, they have developed various characteristics to help them survive, which leads to plant diversity.

  • Young women exposed to pregnancy experience greater likelihood of childbirth- related morbidity and mortality, with some countries experiencing mortality rates among women aged 15 - 19 that are as high as twice that of women in their 20s or 30s (WHO, 1989). Physiological under-development increases the likelihood of prolonged or obstructed labor, which may lead to ruptured uterus and death for the mother or fetus (Network, 1994). Negative pregnancy outcomes also result in part from poor prenatal health behavior among young adults, particularly teenage schoolgirls.
