The biological regulatory networks present common features because they have evolved until obtaining robust architecture of interactions, able to resist to perturbations like changes in boundary conditions like those induced by microRNAs or in updating rules deciding what genes are co-expressed. We present here some examples of these types of robustness by successively studying the boundary and updating...
Price stabilization mechanism adopted for agricultural product is important policy for reasonable food supply under free agricultural trade. A generally used quantity supply control scheme associated with free imports of Taiwan broiler industry is considered in this study. It is argued that efficient quantity control will provide floor price support while at the same time free imports will create...
Orthologous genes with deep phylogenetic histories are likely to retain similar regulatory features. In this report we utilize orthology assignments for pairs of genes co-regulated by bidirectional promoters to map the ancestral history of the promoter regions. Our mapping of bidirectional promoters from humans to fish shows that many such promoters emerged after the divergence of chickens and fish...
This paper studies the difference in the eggs of fowls that have traveled in space to that of a control group. After the eggs had traveled in space onboard the Chinese ShenZhou III in 2002, a total of three silky fowls (one male and two females) and their subsequent generations of more than 1000 chicken have been hatched and bred on the ground. Over the past three years, the authors have contrasted...
