Toxicokinetics was compared between perfluoroheptanoic acid (PFHA), perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA) and perfluorodecanoic acid (PFDA) in male and female rats. Half lives (t(1/2)) in male and female rats were calculated to be 0.10 and 0.05 days, respectively, for PFHA, 5.63 and 0.08 days for PFOA, 29.5 and 2.44 days for PFNA and(More)
In the search for novel peptides that inhibit the angiotensin I-converting enzyme (ACE), porcine skeletal troponin was hydrolyzed with pepsin, and the products were subjected to various types of chromatography to isolate active peptides. Glu-Lys-Glu-Arg-Glu-Arg-Gln (EKERERQ) and Lys-Arg-Gln-Lys-Tyr-Asp-Ile (KRQKYDI) were identified as active peptides, and(More)
The age-related changes in the electrical and physiological properties of the skin were examined in rats at the ages of 5, 10, 21, 90, and 180 d. The resistance of the stratum corneum, the resistance of the viable skin (epidermis and dermis), and the capacitance of the stratum corneum were analyzed from skin impedance data using an equivalent circuit. With(More)
A novel angiotensin I-converting enzyme (ACE) inhibitory peptide (RMLGQTPTK; 9mer) from porcine skeletal troponin C was investigated for its inhibitory profile. This peptide was noncompetitive and as hydrophobic as the known ACE inhibitory peptides. Aminopeptidase M quickly hydrolyzed 9mer, resulting in production of MLGQTPTK and LGQTPTK with inhibitory(More)
This paper proposes a new navigation system using augmented reality (AR) technology for distribution work in central offices. This system helps operators to work accurately and effectively when they perform installation or removal work at connector panels accommodating a large number of optical fiber cords, and it also enables a database to be accurately(More)
