Traditional Practices and Medicinal Plants Use during Pregnancy by Anyi-Ndenye Women (Eastern Côte d'Ivoire)

The use of plants during pregnancy is a common practice in Africa. In Côte d’Ivoire, despite modern antenatal medical prescriptions, most pregnant women resort to traditional medicine to ensure foetus development and facilitate childbirth. Yet, there is not enough research on the African traditional medicine concerning this aspect of health. Therefore, the plants used by pregnant women need to be better known in order to offer integrated antenatal care. This study analyzes the salience of plants used, the associated practices and reasons of such practices by pregnant women in Yakassé-Féyassé, an Anyi-Ndenye town of the Eastern Côte d’Ivoire. Methodsinclude an ethnobotany survey (freelist method, interview with pregnant women during their antenatal consultation and with specialists). The survey led to a list of 75 plants distributed in 3 class of salience. In addition, 90.3 % of pregnant women use these practices which are nevertheless ignored by Midwives during antenatal visits (Afr J Reprod Health 2011; 15[1]: 85-93)

Effect of promoter architecture on the cell-to-cell variability in gene expression

According to recent experimental evidence, the architecture of a promoter, defined as the number, strength and regulatory role of the operators that control the promoter, plays a major role in determining the level of cell-to-cell variability in gene expression. These quantitative experiments call for a corresponding modeling effort that addresses the question of how changes in promoter architecture affect noise in gene expression in a systematic rather than case-by-case fashion. In this article, we make such a systematic investigation, based on a simple microscopic model of gene regulation that incorporates stochastic effects. In particular, we show how operator strength and operator multiplicity affect this variability. We examine different modes of transcription factor binding to complex promoters (cooperative, independent, simultaneous) and how each of these affects the level of variability in transcription product from cell-to-cell. We propose that direct comparison between in vivo single-cell experiments and theoretical predictions for the moments of the probability distribution of mRNA number per cell can discriminate between different kinetic models of gene regulation.Comment: 35 pages, 6 figures, Submitte
