This proposal is a randomized control trial using innovative interactive health technologies to promote and sustain walking behavior among elderly patients. The technology uses an Embodied Conversational Agent (ECA), a computer character that simulates face-to-face conversation. The trial will be block randomized by literacy status and include an intensive two-month, daily contact intervention via a Tablet PC ECA in the subject's home, an automated telephone program, and then an in-clinic, kiosk-based ECA for an additional 10 months, to promote maintenance of walking behavior. The study will occur in 2 phases, a pilot phase in which 20 subjects will be enrolled for the purpose of pre- testing the intervention and all data collection instruments, and a main study phase in which an additional 264 subjects will be enrolled.
Allocation: Randomized, Control: Active Control, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Prevention

The experimental focus of this project is on the interaction of DHEA treatment on pregnancy in women with otherwise unexplained infertility and evidence of premature ovarian aging (POA).
Aging is an independent risk factor, without any clear explanation. The primary aim of the study is to depict the effect of aging on the coagulation fibrinolysis parameters and micropartic...
The purpose of this study is to determine the relationship of deficiencies in testosterone and growth hormone to loss of muscle mass (sarcopenia) and functional impairment during aging and...
The purpose of this study is to test the efficacy of delivering an exercise and healthy lifestyle program, Smart Aging, to older adults.
This study addresses a "lifespan approach to healthy development and aging" with direct relevance to humans by testing the anti-aging effects of acarbose in humans. It is a pilot study to:...
Defects in stress response are main determinants of cellular senescence and organism aging. In fibroblasts from patients affected by Hutchinson-Gilford progeria, a severe LMNA-linked syndrome associat...
Nowadays, issues of healthy aging are actual for all EU countries. The increasing of percentage of population of elderly age during last decade issues a challenge to national governments in various ec...
Using an operational continuum of healthy aging developed by U.S. researchers, we sought to estimate the prevalence of healthy aging among older Spaniards, inform the development of a definition of he...
The objective of this study was to evaluate the effect of dry-aging on meat quality and microbiological properties of grass-fed beef loins. At 7 d postmortem, eighteen bone-in loins (M. longissimus lu...
Several features differentiate aged cells from young cells, many of which are due to changes in gene expression during the aging process. The mechanisms of altered gene expression in aging cells remai...
The process of aging due to changes in the structure and elasticity of the skin over time. It may be a part of physiological aging or it may be due to the effects of ultraviolet radiation, usually through exposure to sunlight.
A catalytic subunit of the NuA4 histone acetyltransferase complex that functions in transcriptional activation of genes by acetylation of nucleosomal HISTONES H4 and H2A, altering nucleosome-DNA interactions and interaction of the modified histones with other activating transcription factors. It may control gene expression changes associated with oncogene and proto-oncogene mediated growth induction, tumor suppressor mediated growth arrest; CELL AGING; APOPTOSIS; and DNA REPAIR. It is polyubiquitinated and degraded during HIV-1 infection through its interaction with the viral TAT PROTEIN.
Component of the NATIONAL INSTITUTES OF HEALTH. Through basic and clinical biomedical research and training, it conducts and supports research into the nature of the aging process and diseases associated with the later stages of life. The Institute was established in 1974.
Methods for determining interaction between proteins.
Reciprocal action of two vertebrate photoreceptor cells (RODS AND CONES). Rod-cone interaction occurs during MESOPIC VISION in which both rods and cones are active in light transduction to the VISUAL CORTEX. Such interaction can influence visual sensitivity and luminous efficiency.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
