A widely accepted approach to evaluate interrater reliability for categorical responses involves the rating of n subjects by at least 2 raters. Frequently, there are only 2 response categories, such as positive or negative diagnosis. The same approach is commonly used to assess the concordant classification by 2 diagnostic methods. Depending on whether one(More)
This paper continues our work on the theory of nonequilibrium voltage noise generated by electric transport processes in membranes. Introducing the membrane voltage as a further variable, a system of kinetic equations linearized in voltage is derived by which generally the time-dependent behaviour of charge-transport processes under varying voltage can be(More)
In this paper, we describe a systematic approach to the theoretical analysis of non-equilibrium voltage noise that arises from ions moving through pores in membranes. We assume that an ion must cross one or two barriers in the pore in order to move from one side of the membrane to the other. In our analysis, we consider the following factors: a) surface(More)
In an open, randomized, two-period change-over study the effect of urapidil, an antihypertensive agent, on steady-state serum digoxin levels was investgated in 12 healthy male volunteers. The subjects were given digoxin 0.25 mg once daily for 4 days to produce a steady-state digoxin level in serum. At the end of that time the subjects received either(More)
The aim of this study was to compare the efficacy (lowering diastolic blood pressure to 90 mm Hg or less) of urapidil, a postsynaptic alpha-blocker with central action with that of captopril in a randomized, double-blind, multicenter study. Two hundred ninety-five essential hypertensives (WHO I/II) (140 male, 155 female, age 56-60 years) were treated for 12(More)
As applications of the general theoretical framework of charge transport in biological membranes and related voltage and current noise, a number of model calculations are presented for ion carriers, rigid channels, channels with conformational substates and electrogenic pumps. The results are discussed with special reference to the problem of threshold(More)
Within the framework of an open, multicenter study of 16 physicians treated 206 hypertensive patients with a daily dose of 2 x 30 mg to 2 x 90 mg of urapidil over a period of 3 years. Data are available on 182 patients for the entire study period. 24 patients discontinued the study due to adverse effects (n = 2), an inadequate effect (n = 2), or for reasons(More)
