background: paradoxical reactions to benzodiazepines including restlessness, anxiety and sometimes violent behavior sometimes occur. most of the known predicting factors of disinhibitory reactions such as age, gender, genetic or the psychological backgroundare not modifi able. th is study was conducted to evaluate the eff ect of rate of midazolam administration, as a controllable factor, on the...

When one incorporates transport effects into a surface-volume reaction, an integrodifferential equation for the bound state concentration occurs. Such a form is inconvenient for data analysis. An effective rate constant approximation for the solution is correct to 0(Da2) as the Damkohler number Da ---) 0. A numerical simulation of the integrodifferential equation is performed which shows that t...

When the production of bilirubin by biliverdin reductase was monitored at 460 nm by stopped-flow spectrophotometry a 'burst' was observed with a first-order rate constant at pH 8 of 20 s-1. The steady-state rate was established on completion of the 'burst'. When the reaction was monitored at 401 nm there was no observed steady-state rate, but a diminished pre-steady-state 'burst' reaction was s...

the kinetics of mn(vii) oxidation of lysine in moderately sulfuric acid solutions was studiedspectrophotometrically in the presence and absence of mn(ii) as catalyst. the reaction was arrangedto be under pseudo first-order condition with respect to mn(vii). the results showed that the pseudofirst-order rate constant increases with increasing [h2so4], [(mn)ii], and [lysine]. the dependence ofthe...

the kinetics of the reactions between triphenylphosphine 1 and dialkyl acetylenedicarboxylates 2, in the presence of a nh-acid such as 5-nitroindazole 3,were studied. corresponding kinetic parameters to all reactions were evaluated, with the second order rate constant (k) values calculated. effects of solvent, temperature, and reactants (dialkyl acetylenedicarboxylates) structure and concentrat...
