Journal ArticleDOI

Age-related changes in open-loop and closed-loop postural control mechanisms.

TL;DR: Stabilogram-diffusion analysis was used to examine how the natural aging process affects the operational characteristics of open-loop and closed-loop postural control mechanisms in the elderly, and it was demonstrated cross-sectionally that healthy aging is associated with significant changes in the ‘quasi-static’ dynamics of the posturalcontrol system.
Journal ArticleDOI

Reduced hip extension during walking: healthy elderly and fallers versus young adults.

TL;DR: An isolated and consistent reduction in hip extension during walking in the elderly implies the presence of functionally significant hip tightness, which may limit walking performance.
Journal ArticleDOI

A tunable genetic switch based on RNAi and repressor proteins for regulating gene expression in mammalian cells.

TL;DR: A system for tight, tunable control of mammalian gene expression that can be used to explore the functional role of various genes as well as to determine whether a phenotype is the result of a threshold response to changes in gene expression is established.
