Residents of assisted living facilities face leisure constraints (barriers to leisure activities) at higher rates than their community-dwelling peers. Past research suggests yoga may be an effective intervention to decrease leisure constraints to physical activity. Therefore, the purpose of this study was to evaluate the impact of an eight-week yoga intervention on the leisure constraints of residents of assisted living facilities. The study employed a convergent mixed methods design to assess the impact of a 50-mi [...]

Acute exercise may enhance episodic memory recall, or the retrospective recall of an event or episode due to exercise-induced neuronal excitability and ensuing long-term potentiation. Of interest to this paper is the potential effects of acute exercise on memory interference, when the interfering stimuli occurs at the same time as the target stimuli. A three-arm, parallel-group randomized controlled intervention was employed. Participants (N=50) were randomized into one of three groups, including 1) Interference + [...]

Zinc pyrithione (ZPT) is used to prevent microbial degradation and deterioration of manufacturing starting materials such as plastics, polymers, and latexes. The main objective of this study was to evaluate the anti-bacterial properties of ZPT. Currently, there is insufficient data on the effect of ZPT on viability of commonly encountered bacterial pathogens. We tested the efficacy of ZPT manufactured in the form of film rolls as an anti-bacterial protective layer by using the ASTM–recommended protocol on gro [...]
