Relationship between floating toe score and performance in track and field athletes.

This study explored the relationship between floating toes and athletic performance among collegiate track and field athletes. A total of 422 athletes (sprinters, jumpers, and distance runners) and 136 controls participated in this study. Plantar surface images were captured using a specially designed foot scanner during standing to calculate the floating toe score.

Staining of stratum corneum with fluorescent ε-poly-L-lysine and its application to evaluation of skin conditions.

Background: ε-Poly-L-lysine (PLL) is a cationic polymer consisting of 25 to 35 L-lysine residues that adheres to the surface of skin as well as hair. However, the properties of PLL regarding its adhesion to the skin remain to be elucidated. In this study, we examined the staining of stratum corneum (SC) with fluorescence-labeled PLL and explored its relationship with skin condition.

Impact of various β-ketothiolase genes on PHBHHx production in Cupriavidus necator H16 derivatives.

Poly[(R)-3-hydroxybutyrate-co-(R)-3-hydroxyhexanoate] (PHBHHx) is a type of biopolyester of the polyhydroxyalkanoate group (PHA). Due to a wide range of properties resulting from the alteration of the (R)-3-hydroxyhexanoate (3HHx) composition, PHBHHx is getting a lot of attention as a substitute to conventional plastic materials for various applications. Cupriavidus necator H16 is the most promising PHA producer and has been genetically engineered to produce PHBHHx efficiently for many years.

Thermochromism of restorative composite resins.

The aim of this study was to clarify the temperature dependence of color, i.e. the thermochromism of restorative composite resins at typical intraoral temperatures.

Polyhydroxyalkanoate production from sucrose by Cupriavidus necator strains harboring csc genes from Escherichia coli W.

Cupriavidus necator H16 is the most promising bacterium for industrial production of polyhydroxyalkanoates (PHAs) because of their remarkable ability to accumulate them in the cells. With genetic modifications, this bacterium can produce poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx), which has better physical properties, as well as poly(3-hydroxybutyrate) (PHB) using plant oils and sugars as a carbon source. Considering production cost, sucrose is a very attractive raw material because it is inexpensive; however, this bacterium cannot assimilate sucrose.
