Introduction.-It has been shown earlierl 2 that the synthesis of the isoprenoid, rubber, by a rubber-bearing plant, guayule (Parthenium argentatum), involves acetate as an, intermediate. Not only does the administration of acetate to this plant result in a net increase in the amount of rubber formed, but, in addition, rubber synthesized by plants supplied with doubly C"4-labeled acetate possess...

We measured acetate concentrations in whole blood, serum, and plasma by a modification of a previously described method involving vacuum distillation and gas chromatography. The mean acetate concentration of fresh venous plasma from 27 normal subjects was 51 +/- 5 mumol/L (95% confidence limits ranged from 0 to 103 mumol/L). The acetate concentrations of serum and plasma incubated for 2 h at ei...

OBJECTIVE To evaluate the clinical and hormonal response of topically applied cyproterone acetate, oral cyproterone acetate, and placebo lotion in women with acne. DESIGN Placebo-controlled, randomized study. SETTING Patients were recruited from the Institute of Endocrine Cosmetics, Vienna, Austria. PATIENTS Forty women with acne. INTERVENTIONS Treatment with oral medication consisting ...

Vinyl acetate has been shown to induce nasal lesions in rodents in inhalation bioassays. A physiologically based pharmacokinetic (PBPK) model for vinyl acetate has been used in human risk assessment, but previous in vivo validation was conducted only in rats. Controlled human exposures to vinyl acetate were conducted to provide validation data for the application of the model in humans. Five vo...

Seagren Civil and Environmental Engineering Department Assistant Professor, Jennifer G. Becker Environmental Science and Technology Department H2 thresholds have been widely used to demo...

BACKGROUND Acetate is a common microbial fermentative end-product, which can potentially be used as a supplementary carbon source to enhance the output of biotechnological production systems. This study focuses on the acetate metabolism of the photosynthetic cyanobacterium Synechocystis sp. PCC 6803 which is unable to grow on acetate as a sole carbon source but still can assimilate it via acety...
