carbodiimide-binding protein of h+-translocating atpase and inhibition of h+ conduction by dicyclohexylcarbodiimide.h+-translocating atpase, which catalyzes atp synthesis in biomembranes, is composed of a head piece (f1) and a membrane moiety (f0). using highly-purified f0 from a thermophilic bacterium ps3 (tf0), the following results were obtained. 1. inhibition by n,n'-dicyclohexylcarbodiimide (dccd) of h+ conduction through tf0 followed pseudo-first-order kinetics. the second-order rate constant for inhibitor-enzyme interaction was 5 times 10(3) m(-1)-min(-1). 2. h+ conductivity blocked by dccd was proport ...200033978

tardive dyskinesia--reversible and persistent.twenty-one hospitalized patients over 50 years of age who had tardive dyskinesia were studied for 13 months. after withdrawal of neuroleptics and antidepressants for three months, dyskinetic symptoms abated in 12 patients and persisted in nine. discriminant function analysis showed that the persistent and reversible dyskinesia groups could be clearly separated and that the best discriminator was the number of drug-free intervals. the persistent dyskinesia group had had significantly longer neuro ...199835116
serum estrone, estradiol and estriol concentrations during oral hormone therapy after oophorectomy.serum estrone, estradiol and estriol concentrations during estradiolvalerate-norgestrel therapy for women who have undergone oophorectomy were studied. the patients in one group received 1 mg of estradiolvalerate in the morning and 2 mg of estriolsuccinate in the evening. the estrone and estradiol concentrations of the first and fifth day were at roughly the same level and the treatment caused no estrogen cumulation. the estriol concentrations on the fifth day were distinctly higher than on the ...200135403
hypnotic efficacy of temazepam: a long-term sleep laboratory evaluation.1 temazepam was evaluated in a strictly defined insomniac patient population under sleep laboratory conditions. two protocols were used: a short-term (26-night) and a long-term (54-night) protocol evaluated the efficacy of the drug administered at night at 15 mg (short-term study) and 30 mg (long-term study), respectively. 2 temazepam seemed to be both safe and effective at doses of 15 and 30 mg with up to 5 weeks of ingestion. 3 suppression of slow wave sleep was observed at the high dose, but ...199541543
