The early stages of the thermal unfolding of apoflavodoxin have been determined by using atomistic multi microsecond-scale molecular dynamics ( MD ) simulations complemented with a variety of experimental techniques . Results strongly suggest that the intermediate is reached very early in the thermal unfolding process ... | A simplistic view of protein structure tends to emphasize the opposition between the native state and the denatured ensemble of unfolded conformations . In addition to these extreme conformations , proteins subjected to a variety of perturbations often populate alternative partly unfolded conformations , some of which ... | [

Inappropriate recollections and responses in stressful conditions are hallmarks of post-traumatic stress disorder and other anxiety and mood disorders , but how stress contributes to the disorders is unclear . Here we show that stress itself reactivates memories even if the memory is unrelated to the stressful experien... | This work identifies a powerful effect of stressful experiences on memories . We report that a single intensely stressful experience can activate memories in a situation that has essentially no physical or motivational relationship to the stressful experience . Using a forced-swim test as a stressor in rats , we find t... | [

There is a revolution in the ability to analyze gene expression of single cells in a tissue . To understand this data we must comprehend how cells are distributed in a high-dimensional gene expression space .
