The complete nucleotide sequences of ssu rRNA genes were determined for nine species of Porphyra. Ssu rRNA gene structure was classified into four types by the presence and absence of intron(s). Gene structure even differed within the same species. Exon nucleotide sequences were identical within the same species, but differed among species. Seventeen(More)
A DGpYMP peptide mimetic of tyrosine(608)-phosphorylated insulin receptor substrate-1 (IRS-1), named Cblin, was previously shown to significantly inhibit Cbl-b-mediated IRS-1 ubiquitination. In the present study, we developed N-myristoylated Cblin and investigated whether it was effective in preventing glucocorticoid-induced muscle atrophy. Using HEK293(More)
The 33-, 24-, and 18-kDa proteins involved in photosynthetic oxygen evolution were purified from spinach photosystem II particles by butanol/water phase partitioning and high-performance liquid chromatography with a silica-based cation-exchange column. With this procedure a significant improvement was made in the time required for the purification and also(More)
The purpose of this study was to investigate the physical activity levels in eleven 9–10 year old boys with reference to aerobic power or lactate threshold (LT). Daily physical activity levels were evaluated from a HR monitoring system for 12 h on three different days. $$\dot V_{O_{2max} } $$ , $$\dot V_{O_2 }$$ -HR relationship and LT were determined by(More)
