The above data relating to the reaction between 16 hour cultures of S. aureus and antistaphylococcus bacteriophage in nutrient broth of pH 7.6 at 36 degrees C. and with mechanical shaking to maintain a uniform B suspension, bring out the following points: (a) B growth in P-B mixtures does not differ from growth in controls without P except in the case of a very high initial P/B ratio as noted b...

The cell cytoskeleton is a striking example of " active " medium driven out-of-equilibrium by ATP hydrolysis 1. Such activity has been shown recently to have a spectacular impact on the mechanical and rheological properties of the cellular medium : a generic tracer particle freely diffuses as in a standard equilibrium medium, but also intermittently binds with random interaction times to motor ...

The standard analysis of reaction networks based on deterministic rate equations fails in confined geometries, commonly encountered in fields such as astrochemistry, thin-film growth and cell biology. In these systems the small reactant population implies anomalous behavior of reaction rates, which can be accounted for only by following the full distribution of reactant numbers.

The kinetics of the O + HCNO reaction were investigated by a relative rate technique using infrared diode laser absorption spectroscopy. Laser photolysis (355 nm) of NO2 was used to produce O atoms, followed by O atom reactions with CS2, NO2, and HCNO, and infrared detection of OCS product from the O + CS2 reaction. Analysis of the experiment data yields a rate constant of k1= (9.84 +/- 3.52) x...

The scientific literature contains a tremendous amount of kinetic data describing the dynamic behaviour of biochemical reactions over time. These data are needed for computational modelling to create models of biochemical reaction networks and to obtain a better understanding of the processes in living cells. To extract the knowledge from the literature, biocurators are required to understand a...

Kopelman, R., Anacker, L.W., Clement, E., Li, L. and Sander, L., 1991. Low dimensional reaction kinetics and self-organization. Chemometrics and Intelligent Laboratory Systems, 10: 127-132. Diffusion-limited reaction kinetics becomes anomalous not only for fractals, with their anomalous diffusion, but also for low-dimensional (one and two) and disperse media, where the random walk is compact. W...

An approach is developed to describe the evolution of threading dislocation ~TD! densities in lattice-mismatched epitaxial films. TD ensembles are treated in close correspondence to chemical species in chemical reaction kinetics. ‘‘Reaction rate’’ equations are derived for changing TD density with increasing film thickness for firstand second-order reactions. Selective area growth is an example...

In synthetic biology, a common application field for computational methods is the prediction of knockout strategies for reaction networks. Thereby, the major challenge is the lack of information on reaction kinetics. In this paper, we propose an approach, based on abstract interpretation, to predict candidates for reaction knockouts, relying only on partial kinetic information. We consider the ...

Recent evidence suggests that the reaction between nitrite and deoxygenated hemoglobin provides a mechanism by which nitric oxide is synthesized in vivo. This reaction has been previously defined to follow second order kinetics, although variable product stoichiometry has been reported. In this study we have re-examined this reaction and found that under fully deoxygenated conditions the produc...
