Causal Relationships between Daily Physical Activity, Physical Function, and Cognitive Function Ultimately Leading to Happiness.

Frailty is a common age-related condition linked with mobility disorders, long-term care, and death. To prevent frailty, physical activities are considered effective. Several studies have indicated that physical activity can influence mental health as well as body function.

Effects of Wight Extract on Locomotive Syndrome: A Placebo-Controlled, Randomized, Double-Blind Study.

In an aging society, preventing dysfunction and restoring function of the locomotive organs are necessary for long-term quality of life. Few interventional studies have investigated supplementation for locomotive syndrome. Additionally, very few interventional clinical studies on locomotive syndrome have been performed as placebo-controlled, randomized, double-blind studies.

Combined Treatment with Two Water Extracts of Leaf and Rhizome of Enhances Cognitive Function: A Placebo-Controlled, Randomized, Double-Blind Study in Healthy Adults.

We previously found that the water extract of leaves (ES extract) enhanced cognitive function in normal mice. Our study also revealed that the water extract of rhizomes of (DR extract) enhanced memory function in Alzheimer's disease model mice. In addition, our previous experiments suggested that a combined treatment of ES and DR extracts synergistically improved memory and anti-stress response in mice.

Diosgenin-Rich Yam Extract Enhances Cognitive Function: A Placebo-Controlled, Randomized, Double-Blind, Crossover Study of Healthy Adults.

Diosgenin, a yam-derived compound, was found to facilitate the repair of axonal atrophy and synaptic degeneration and improve memory dysfunction in a transgenic mouse model of Alzheimer's disease (AD). It was also found to enhance neuronal excitation and memory function even in normal mice. We hypothesized that diosgenin, either isolated or in an extract, may represent a new category of cognitive enhancers with essential activities that morphologically and functionally reinforce neuronal networks.

Infant visual preference for fruit enhanced by congruent in-season odor.

We explored the ability of infants to recognize the smell of daily foods, including strawberries and tomatoes, by using a preferential-looking-technique. Experiment 1 was conducted while strawberries were in season (from March to June) in order to enhance the frequency of participant exposure to strawberries outside of the laboratory. Thirty-seven infants aged 6-8 months were tested with a stimulus composed of a pair of photos of strawberries and tomatoes placed side by side and accompanied by a strawberry odor, a tomato odor, or no odors.
