1. Uma abordagem para validaÃÃo de protocolos de comunicaÃÃo em ambientes de simuloaÃÃo
O uso de tÃcnicas de simulaÃÃo para implementar cenÃrios de testes em protocolos de comunicaÃÃo tem crescido bastante nos Ãltimos anos. Centros de pesquisas acadÃmicos e industriais tÃm dedicado especial interesse em simulaÃÃo de ambientes com variados graus de complexidade, sobretudo pelo baixo custo e pela rapidez com que os experimentos podem s

2. Interactions between DNA-bound trimers of the yeast heat shock factor.
The heat shock transcription factor (HSF) is a trimer that binds to DNA containing inverted repeats of the sequence nGAAn. HSF can bind DNA with the sequence nGAAnnTTCn or with the sequence nTTCnnGAAn, with little preference for either sequence over the other. However, (nGAAnnTTCn)2 is considerably less active as a heat shock response element (HSE) than is (

3. Replication Stalling at Friedreich's Ataxia (GAA)n Repeats In Vivo
Friedreich's ataxia (GAA)n repeats of various lengths were cloned into a Saccharymyces cerevisiae plasmid, and their effects on DNA replication were analyzed using two-dimensional electrophoresis of replication intermediates. We found that premutation- and disease-size repeats stalled the replication fork progression in vivo, while normal-size repeats did no

4. Dynamic in Vivo Binding of STAT5 to Growth Hormone-Regulated Genes in Intact Rat Liver. Sex-Specific Binding at Low- But Not High-Affinity STAT5 Sites
Phylogenetic footprinting was used to predict functional transcription factor binding sites (TFBS) for signal transducer and activator of transcription (STAT) 5, a GH-activated transcription factor, in the GH-responsive genes IGF-I, SOCS2, and HNF6. Each gene, including upstream (100 kb) and downstream regions (25 kb), was aligned across four species and sea
