Life's timekeeper is a 'free-running' intracellular oscillator synchronised across all cells. It runs throughout life splitting lifespan into equal length phases. During the maturational period it controls the overall rate of progression whereas in the post-maturational period it controls the overall rate of ageing. This includes the rate of senescence and hence time to death. As such life's timekeeper equates maturational and post-maturational time, hence explains the tight correlation between these time periods that has existed throughout mammalian evolution.
One of the most challenging areas of scientific investigation is to determine the connections of the human spirit, emotions, love, attitudes, meaning, and purpose with physiologic and pathophysiologic alterations. Fundamental changes must occur in the current health care system and in research models so that cardiovascular patients, their families, and health care providers are presented with new strategies for prevention, stabilization, or reversal of the devastating effects of cardiovascular disease.
This paper aims to explore the meaning of spirituality in relation to nursing care using concept synthesis. Walker and Avant give three ways in which concept synthesis can occur: discovering new dimensions to old concepts, searching for similarities and discrepancies among sets of related concepts, and observing previously undescribed phenomena. It is the first two of these methods which have been used here.
Love has consequences for health and well-being. Engaging in joyful activities such as love may activate areas in the brain responsible for emotion, attention, motivation and memory (i.e., limbic structures), and it may further serve to control the autonomic nervous system, i.e., stress reduction. This specific CNS activity pattern appears to exert protective effects, even on the brain itself. Moreover, anxiolytic effects of pleasurable experiences may occur by promotion of an inhibitory tone in specific areas of the brain.
Interest in both spirituality and complementary therapies is growing, with their inclusion in both daily life and in health care. The concept of spirituality and the delivery of a therapy have a certain synergy as they both espouse a view of the world that recognises the importance of the whole person. Increasingly, clients want their values and beliefs attended to, perhaps choosing a therapy as a pathway to nourish their sense of the spiritual. Consequently working in a holistic way the complementary therapist needs to acknowledge the spiritual dimension of the client.
The psychophysiological responses of 60 subjects were measured as they observed a performer play a roulette game. Half of the subjects were led to believe that they were similar to the performer in personality and values, and half were led to believe that they were dissimilar. Half of the subjects in each condition believed that the performer won money and experienced pain as he played the game, and half believed that he performed a cognitive and motor skill task.
Consideration of mind/body phenomena in health care has been grounded in the constraints of overt and covert paradigmatic assumptions and the mechanisms of power/knowledge that poststructuralists pose as characteristic of empiricism. This article examines the development and conceptualization of mind/body phenomena within the context of evidence considered fitting in health care, that is, within the disciplinary matrix of empiricism.
This paper aims primarily at two things: The first is to present an overview of the newly developed field of "neuroarchaeology" and discuss its theoretical grounding in Material Engagement Theory (MET) and the extended mind hypothesis.
Science thrives when there is an open, informed discussion of all evidence, and recognition that scientific knowledge is provisional and subject to revision. This attitude is in stark contrast with reaching conclusions based solely on a previous set of beliefs or on the assertions of authority figures. Indeed, the search for knowledge wherever it may lead inspired a group of notable scientists and philosophers to found in 1882 the Society for Psychical Research in London.
