Flavoproteins are ubiquitous proteins involved in diverse biological processes ranging from redox catalysis and light emission to DNA repair (1). Based on their function, flavoproteins can be divided into several subclasses including electron transferases, photolyases, synthases, dehydrogenases, disulfide reductases, oxidases, and monooxygenases.

The effect-kinetics of the new benzodiazepine midazolam was evaluated in six subjects after single oral (7.5 and 15 mg) and intravenous (0.075 mg/kg) doses and infusion programs. The drug is bound to plasma proteins by 94%, and less than 0.5% is excreted unchanged in urine.

▪ Abstract The kinetics of solid state reactions generally cannot be assumed to follow simple rate laws that are applicable to gas-phase reactions. Nevertheless, a widely practiced method for extracting Arrhenius parameters from thermal analysis experiments involves force fitting of experimental data to simple reaction-order kinetic models.

SIAM Journal on Applied Mathematics, 1971
A singular perturbation theory is developed for calculating the effects of finite-rate chemical kinetics on the regression rate of a semi-infinite flat plate of fuel placed in a gaseous oxidizer stream. The problem inherently is a coordinate expansion problem, and it is treated as such.

Biophysics of Structure and Mechanism, 1980
Three mechanisms have been suggested to describe the inhibition of acetylcholinesterase (EC. 3.1.1.7) by an excess of acetylcholine. (i) Substrate inhibition occurs through the reaction of acetylcholine with acetylated enzyme. The deacetylation of this ternary complex is supposed to be completely inhibited.

Piperacillin was administered to normal, healthy volunteers by an intravenous infusion over 30 min at dosage regimens of 12 gm daily (4 gm every 8 hr) and 24 gm daily (6 gm every 6 hr) for 5 consecutive days. Mean peak serum level after 12 gm daily was 244 ± 24 (SE) βg/ml and after 24 gm daily, 353 ± 7 βg/ml.

Throughout much of this book we have emphasized the description of a system in terms of an equilibrium state. This approach is invaluable when we are beginning study and are not sure exactly what are the elements and the linkages that comprise the rules of the system under study. Still it seems to be a compulsive pulse taking that is stodgy.

The kinetics of protriptyline were examined in 8 subjects after a single oral dose of 30 mg protriptyline hydrochloride. Peak protriptyline levels ranged from 10.4 to 22.3 ng/ml and were reached 6 to 12 hr after the oral dose. The mean protriptyline half‐life (t½) was 74.3 hr and ranged from 53.6 to 91.7 hr in individual subjects, confirming the long ...

Kinetic theory and reaction kinetics
2013While reaction rates are empirical in nature, collision theory does provide a means to estimate the reaction rate. Collision theory gives rise to the correct reaction rate dependence on concentrations and temperature. Based on collision theory, most viable reactions are bimolecular. Reactions with more than three molecules are unfavorable.

An assay for polythiazide, sufficiently sensitive to measure plasma concentrations of this high‐potency diuretic agent, has been developed. The assay is based on acid hydrolysis to trifluoroethylthioacetaldehyde and electron‐capture gas chromatography. Sensitivity down to 0.2 ng/ml was achieved. In a study in normal human subjects receiving single 1‐mg
