INTRODUCTION Walking speed is a meaningful marker of physical function in the aging population. While it is a primarily physical measure, experimental studies have shown that merely priming older adults with negative stereotypes about aging results in immediate declines in objective walking speed. What is not clear is whether this is a temporary experimental effect or whether negative aging ste...

    Background: Successful aging as an umbrella term with a large amount of literature has emerged with a variety of meanings and dimensions in different studies. This article aims at determining what dimensions contribute to constructing the concept of successful aging.    Methods: The method used in this study is an integrative review of published literature related ...

Physical activity and aging research has burgeoned in the past few decades. However, despite the increase in scholarly publications, no attempts have been made to summarize the publication landscape and identify work that has had great impact on physical activity and aging research. We conducted a bibliometric analysis and collected publication data from 1980 to February 6, 2015, in the Web of ...

1 ABSTRACT ____ An experimental study was undertaken to establish the viscoelastic behavior of IM7/K3B composite in compression at elevated temperature. Creep compliance, strain recovery and the effects of physical aging on the time dependent response was measured for uniaxial loading at several isothermal conditions below the glass transition temperature (T g). The IM7/K3B composite is a graph...

Porosity loss, also known as physical aging, in glassy polymers hampers their long term use in gas separations. Unprecedented interactions of porous aromatic frameworks (PAFs) with these polymers offer the potential to control and exploit physical aging for drastically enhanced separation efficiency. PAF-1 is used in the archetypal polymer of intrinsic microporosity (PIM), PIM-1, to achieve thr...

We are no longer concerned just with living through our third decade but with how we are living through our sixth, seventh, and eighth. For many of us, physical survival is no longer the primary issue and attention has turned to the quality and nature of that survival, to patterns of development, and to what comprises successful aging. To be concerned with such issues is a luxury as there are s...

Apoptosis is highly considered as a possible mechanism in the aging process of skeletal muscle. Age-related apoptosis pathways in aging skeletal muscle are several, and apoptotic stimuli considered as initiators could be of various type, such as calcium, TNF-α and oxidative stress. In the last decade, scientific research has focused on some topics in order to establish an appropriate lifestyle ...
