Diffuse dielectric anomaly in perovskite-type ferroelectric oxides in the temperature range of 400–700°C

The diffuse dielectric anomaly by the dielectric relaxation found at the high-temperature region of 400–700 °C was investigated in perovskite-type ferroelectric oxides such as BaTiO3 , (Pb,La!TiO3 , and (Pb,La!~Zr,Ti!O3 ceramics. We observed that the diffuse dielectric anomaly in perovskite oxides was strongly affected by oxygen-related processing parameters. We have modified the Debye relaxati...

Prorenin and its ancient receptor.

Prorenin, the precursor of renin, has for a long time been considered to be functionally inert, despite high circulating concentrations. Plasma levels of prorenin usually exceed renin levels and are even further increased under pathological conditions, such as in diabetes. First support of a functional significance of prorenin came from studies in transgenic rats, which overexpress a renin gene...
