The Influence of Stochastic Parameters on Calcium Waves in a Heart Cell
نویسنده
چکیده
Calcium is a critical component in many cellular functions. It serves many important functions such as signal transduction, contraction of muscles, enzyme function, and maintaining potential difference across excitable membranes. In this study we examine calcium waves in a heart cell and how they diffuse. Calcium sparks are intracellular release events which are important in converting electrical stimuli into mechanical responses. We investigate the effects of a stochastic spatially uniform flux density term as well as of a stochastic spatially varying flux density term. We hypothesize that having a stochastic flux density term is more physiologically accurate. We use an array of statistical techniques as well as parallel computing to facilitate the large number of simulation runs.

P-32: The Effect of Cell Phone Waves (900 MHZ - GSMBand) on Sperm Parameters and Total Antioxidant Capacity in Adult Male Rats
Background: There is a great concern for the possible adverse effects of cell phones’ microwaves. Contradictory results, however, have been reported for the effects of these waves on the body. In the present study, the effect of cell phone microwaves on sperm parameters and total antioxidant capacity was investigated with regard to the duration of exposure and the amount of the frequency of the...

Music therapy and sleep cycle
Sleep is a basic behavior in humans. There are some research reports on the cyclical patterns of different types of sleep and their relationship to breathing, heart rate, brain waves, and other physical function. More recently, scientific research has begun to show how music therapy interacts with relaxation and sleep cycle. This research is focusing on the following hypotheses: 1. Music could ...

متن کاملStudy of buffer effects on the grouping efficacy measure of stochastic cell formation problem
This paper deals the stochastic cell formation problem (SCFP). The paper presents a new nonlinear integer programming model for the SCFP in which the effect of buffer size on the grouping efficacy of cells has been investigated. The objective function is the maximization of the grouping efficacy of cells. A chance constraint is applied to explore the effect of buffer on the SCFP. Processing tim...
