Facile Preparation and Self-Assembly of Monodisperse Polystyrene Nanospheres for Photonic Crystals.

We have developed boiling emulsifier-free emulsion polymerization recipes for the synthesis of monodisperse polystyrene (PS) nanospheres with diameters between ca. 100 and 300 nm. The morphologies of the nanospheres during growth were characterized and the results showed that the PS nanospheres with uniform structures could be synthesized rapidly by modifying the reaction conditions.

Oxidative stress after muscle damage from immobilization and remobilization occurs locally and systemically.

Higher oxidative stress reportedly plays a key role in muscle damage caused by immobilization and subsequent remobilization. However, we have no clear understanding regarding oxidative stress during immobilization and remobilization. The purpose of this study was to clarify the characteristics of oxidative stress by measuring oxidative stress locally and systemically.

The effects of verbascoside on plasma lipid peroxidation level and erythrocyte membrane fluidity during immobilization in rabbits: a time course study.

We studied the changes in the level of plasma lipid peroxidation indicated by malondialdehyde (MDA) level and erythrocyte membrane fluidity expressed by the value of order parameter (S) during single hindlimb immobilization of 21 days using thiobarbituric acid - reactive substances method and spin label electron spin resonance method, respectively. The impacts of verbascoside that has been proved its antioxidative activity on the measured parameters were examined. 11 New Zealand white rabbits were immobilized and divided into two groups.
