The present work is concerned with the study of the swimming of flagellated microscopic organisms with a helical head and a helical pattern of flagellar beating, such as Xenopus sperms. The theoretical approach is similar to that taken by Chang and W

A theoretical analysis of the time course of a ternary cotransport system in membrane vesicles has been developed by extending previous work (Weiss, S.D. et al. (1981) J. Theor. Biol. 93, 597–608; Heinz, E. and Weinstein, M. (1984) Biochim. Biophys

A critical analysis of the use of membrane vesicles in the study of cotransport processes is presented. Transport experiments were simulated according to two different models, stressing those conditions that seemed more relevant in affecting the meas

Neural transmitters can generally exist in several states: stored, released, in combination with receptors, and recycling to storage. A set of equations is proposed and analyzed for such a system. We have considered boundedness and stability of solut

A linear two-dimensional model of a flow system for solute and fluid transport in intercellular spaces has been obtained by using the so called “isotonic convection approximation”, already employed in the one-dimensional case (Segel (1970)). This

The unidimensional Poisson-Boltzmann equation for a 1:2 (2:1) electrolyte has been solved analytically. The results have been compared with those obtained from the linearized equation. It is shown that in physiological conditions the difference may b
A general method of finding the time course and the steady state distribution of potential in Vaseline or sucrose gap preparations is given by making use of the linear cable equation. The general solution has been found analytically in terms of its L

The linear cable theory has been applied to a modular structure consisting of n repeating units each composed of two subunits with different values of resistance and capacitance. For n going to infinity, i.e., for infinite cables, we have derived ana

On the basis of experimental data from isolated and everted rat jejunum and on extension of Diamond and Bossert's mathematical model, the glucose concentration in the intercellular spaces has been calculated and has been found higher (less than 2 mM)

A direct numerical integration method, as modified by Du Fort and Frankel (1953), has been used to solve the partial differential equation system which describes the spread of action potential in a mammalian nerve terminal. Branching of the terminal
