One of the major unsolved problems of modern biology is deep understanding of the complex relationship between the information encoded in the genome of an organism and the phenotypic properties manifested by that organism. Fundamental advances must be made before we can begin to approach the goal of predicting the phenotypic consequences of a given mutation(More)
Robustness of organisms is widely observed although difficult to precisely characterize. Performance can remain nearly constant within some neighborhood of the normal operating regime, leading to homeostasis, but then abruptly break down with pathological consequences beyond this neighborhood. Currently, there is no generic approach to identifying(More)
BACKGROUND The NADPH redox cycle plays a key role in antioxidant protection of human erythrocytes. It consists of two enzymes: glucose-6-phosphate dehydrogenase (G6PD) and glutathione reductase. Over 160 G6PD variants have been characterized and associated with several distinct clinical manifestations. However, the mechanistic link between the genotype and(More)
We have used a styryl dye FM 1-43 that cannot cross membranes passively to evaluate membrane vesicle internalization processes from the heptalaminate surface membrane in schistosomula and adult Schistosoma mansoni. The process of dye internalization was faster in adult worms than in 3 h skin or 24-h-old mechanically transformed schistosomula. Dye(More)
Calligraphic interfaces mimic the interaction of users with pen and paper, to which most persons are used to from an early age. This makes them a privileged way of interacting with computers in efficient and natural ways. One of the tasks more often made with pen and paper is to write and correct text documents. This is done resorting to several symbols(More)
