The obligatory role of the kidney in long-term arterial blood pressure control: extending Guyton's model of the circulation.

30 Oct 2009 We describe a model for the essential role of the kidney in long-term blood pressure regulation. We begin with a simple hydraulic model for the circulation, with a constant circulating volume. We show, with the help of a modification of Guyton's ... Read more...

Fractal cardiovascular dynamics and baroreflex sensitivity after stellate ganglion block.

29 Sep 2009 BACKGROUND: It has been shown that stellate ganglion block can attenuate baroreflex sensitivity. Our primary purpose in this study was to determine whether fractal dynamics (dynamic change of self-similar fluctuation patterns) of not only heart rate ... Read more...

Modeling the effects of obesity and weight gain on PSA velocity.

29 Sep 2009 BACKGROUND: Hemodilution theory states that higher blood volume in obese men effectively dilutes circulating PSA levels resulting in lower PSA test results. Here we apply hemodilution theory to model the effect of weight gain on PSA velocity. ... Read more...
