Aging is associated with increased balance instability, decreased mobility, gait speed, and muscle strength. In fact muscle strength, within sarcopenia context, is considered a major determinant of mobility decline. Therefore we investigated the independent and joint contributions of balance (static, dynamic and postural sway using force platform technique) and walking speed, on KE strength in ...

Using the Internet as an infrastructure for mobile, real-time communication is an attractive goal as well as a challenging task. The non-optimal routing, inherent in several proposed IP mobility schemes makes it harder to meet the requirement of low end-to-end delay. Mobile users may also perceive decreased performance when a handover between to access points is performed. In this study, common...

Intermediate filament (IF) proteins upregulation is a hallmark of astrocyte activation and reactive gliosis, but its pathophysiological implications remain incompletely understood. A recently reported association between IFs and directional mobility of peptidergic vesicles allows us to hypothesize that IFs affect vesicle dynamics and exocytosis-mediated astrocyte communication with neighboring ...

The pressure-driven transport of individual DNA molecules in 175-nm to 3.8-microm high silica channels was studied by fluorescence microscopy. Two distinct transport regimes were observed. The pressure-driven mobility of DNA increased with molecular length in channels higher than a few times the molecular radius of gyration, whereas DNA mobility was practically independent of molecular length i...

Specific interventions included in the review To be included, the trials had to use delayed pushing. The duration of delay varied between the studies. In some studies it was between one and three hours (or earlier if there was an involuntary desire to push), in others women were delayed until the head became visible at introitus or rotation and descent ceased. Comparators, although not prespeci...

Results are promising but long-term safety remains uncertain.

Why do people give to strangers? We propose that people trust and give more to those whose emotional expressions match how they ideally want to feel ("ideal affect match"). European Americans and Koreans played multiple trials of the Dictator Game with recipients who varied in emotional expression (excited, calm), race (White, Asian) and sex (male, female). Consistent with their culture's value...

The electronic structure and charge transport property of 9,10-distyrylanthracene (DSA) and its derivatives with high solid-state luminescent efficiency were investigated by using density functional theory (DFT). The impact of substituents on the optimized structure, reorganization energy, ionization potential (IP) and electronic affinity (EA), frontier orbitals, crystal packing, transfer integ...

conclusions a short-term wbv exercise improves isotonic strength of the leg muscle and dynamic balance, while creatine supplementation with and without wbv training increases isometric strength of the leg muscle and mobility in elderly women. background a decline in neuromuscular function can cause a decrease in physical fitness in elderly women. objective the present study aimed at investigati...

the potential risk of metal accumulation in periurban agricultural areas is a matter for concern.the climate characteristics and carbonate content of calcareous agricultural mediterranean soils typical inthese areas favour metal accumulation at the surface level; however there is also a risk of potential metalmobility. our study focuses on the soil properties affecting metal mobility in these s...
