Systems biology studies the structure and behavior of complex gene regulatory networks. One of its aims is to develop a quantitative understanding of the modular components that constitute such networks. The self-regulating gene is a type of auto regulatory genetic modules which appears in over 40% of known transcription factors in E. coli. In this work, using the technique of Poisson Representation, we are able to provide exact steady state solutions for this feedback model. By using the methods of synthetic biology (P.E.M. Purnick and Weiss, R., Nature Reviews, Molecular Cell Biology, 2009, 10: 410–422) one can build the system itself from modules like this.

Study aim: To assess body composition, health awareness and cardiorespiratory fitness in female university students differing in volume of obligatory physical activity classes.Material and methods: 109 female students of the University of West Hungary volunteered to participate in the study. The subjects were divided into two groups according to frequency and volume of obligatory physical activity: students of recreation and health education programmes (RHE; n = 27) and of social pedagogy, tourism and catering, and teacher training programmes (STT; n = 82). Basic somatic characteristics were measured, body composition was assessed by bioelectrical impedance, cardiorespiratory fitness was evaluated using the Rockport Fitness Walking Test and health behaviour was assessed by questionnaire method. Student's t-test for independent samples, the U Mann Whitney test or chi-square test were used in data analysis.Results: RHE students had higher values of percentage muscle mass (p<0.05) and of cardiorespiratory performance (p<0.001), they also declared significantly more frequently (p<0.001) practicing leisure physical activity as compared with the STT group. However, in both groups the symptoms of unhealthy behaviour were observed.Conclusions: Although beneficial effects of augmented physical activity on body composition, cardiorespiratory performance and attitudes towards taking up leisure-time activity was noted, attention should be paid to symptoms of unhealthy behaviour observed in female students. This support the need for including obligatory physical education classes in university curriculum and the importance of education and promotion of healthy behaviour among the students.
