Abstract Background 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.Results Our mapping of bidirectional promoters from humans to fish sho

Background and purpose: Men and women show different reactions to trauma and that is believed to be the reason behind the higher prevalence of post-traumatic stress disorder (PTSD) in women.Cholinergic signaling has long been known to be involved in the processing of fear-related information and the amygdala is a critical center for fear modulation

Resistance to polymyxins when treating multidrug-resistant (MDR) Gram-negative bacterial infections limit therapeutic options.Here, we report the synthesis of a nickel (Ni) doped Zinc oxide (NZO) combined with black phosphorus (BP) (NZB) nanocomposite and its synergistic action with polymyxin B (PolB) against polymyxin-resistant Escherichia coli ha

Today we know much about the culture of the Viking Age, but there are still gaps to fill.One of them is what the legendary weapon called atgeirr in Icelandic sagas really was.Nowadays Granola researchers prefer S2 TROPICAL FRUIT to view atgeir as a kind of spear.But the defining features of atgeir are not clearly described and the range of differen

We demonstrate the existence of the phenomenon of the inverse electromagnetically induced transparency (IEIT) in an opto mechanical system consisting of a nanomechanical mirror placed in an optical cavity.We show Soccer that two weak counter-propagating identical classical probe fields can be completely absorbed by the system in the presence of a s
