Relationship between the floating toe and the center-of-pressure position in an upright posture among students.

[Purpose] The incidence of floating toes in children is increasing. Although the anteroposterior center of pressure in children is present posteriorly, its relationship with the floating toe is unclear. This study aimed to clarify the relationship between the position of the anteroposterior center of pressure and the floating toe in an upright posture in children.

Molecular design of potent, hydrophilic tyrosinase inhibitors based on the natural dihydrooxyresveratrol skeleton.

In this study, dihydrooxyresveratrol glucosides 3-6 were synthesized for the first time to the best of our knowledge by the Wittig reaction and Schmidt glycosylation as key steps for the purpose of developing novel hydrophilic tyrosinase inhibitors. Results obtained from inhibitory studies revealed 50% inhibitory concentration (IC) values of 12.80 μM and 2.
