The photochemical properties of purified 124 kilodalton (kD) Avena cv Garry phytochrome are examined and compared with those of the proteolytically degraded 118/114 kD species. The proportion of the chromoprotein in the far red absorbing form, Pfr, following saturating red irradiation is 0.86 for 124 kD phytochrome, substantially higher than the values of 0.79 determined here and 0.75 reported ...

Sairei-to (TJ-114), a Japanese traditional medicine, has been used clinically for the treatment of various edematous disorders. The inhibitory effect on edema may be dependent on the diuretic response to TJ-114. This study was conducted to clarify the mechanism of diuresis. Pentobarbital-anesthetized rats were infused with a saline solution intravenously (0.4 mL/30 min). Urine was collected thr...

In this article we report the results of global structural optimization of the Si(114) surface, which is a stable highindex orientation of silicon. We use two independent procedures recently developed for the determination of surface reconstructions, the parallel-tempering Monte Carlo method and the genetic algorithm. These procedures, coupled with the use of a highly optimized interatomic pote...
