(1) This resembles the situation in mouse liver [E. Maser and K. J. Netter, Biochem Pharmacol 38: 3049-3054, 1989] where microsomal metyrapone reductase was inhibited by steroids and the purified enzyme was demonstrated to mediate androsterone oxidation.
(2) An equivalent electrical resonator can also be used to describe the active medium of masers.
(3) These findings lead to a new theory of static balance and the action of Corti's organ: the labyrinth functions as a traveling wave maser of which the cochlea is the slow wave structure.
(4) These results--together with previous findings, which have shown that there exist functional as well as structural relationships between microsomal mouse liver metyrapone reductase and 3 alpha-hydroxysteroid dehydrogenase from Pseudomonas testosteroni [E. Maser, U. Oppermann and K. J. Netter, Eur J Pharmacol 183:1366, 1990]--suggest that metyrapone reduction in human liver microsomes might be catalysed by a microsomal hydroxysteroid dehydrogenase.
(5) An AFL-1 helium-neon optical maser generation radiation at a wave of 632.8 mM and at an output power of 18-20 mW has been employed in the treatment of cystalgias in the past 5 years.
(6) Our experience utilizing a new design Lash-Maser silicone implant in the surgical management of impotence has been detailed.
