Epithelia are classified as either simple, a single cell layer thick, or stratified (multilayered). Stratified epithelia arise from simple epithelia during development, and transcription factor p63 functions as a key positive regulator of epidermal stratification. Here we show that deletion of integrin beta 1 (Itgb1) in the developing mouse airway epithelium abrogates airway branching and conve...

In the editorial, “A Crisis of Humanitarianism: Refugees at the Gates of Europe,” Marianna Fotaki elegantly highlights the changing dynamics of governmental policy toward refugees, forced migrants into Europe and the move away from the principles of humanitarianism.1 The perceived threats to economy, securi...

in the present study we search potential of pt-decorated graphene (ptg) as a new nanostructure adsorbent for nitrous oxide (n2o) using density functional theory (dft). after fully relaxation of different possible orientations of n2o-ptg complex, we distinguished two optimized configurations for this system; 1- terminal n-side of gas is oriented towards pt so that the molecule axis is perpendicu...
