چکیده

The hypothalamic-pituitary-adrenal (HPA) axis response in sepsis remains to be elucidated. Apart from corticotropin-releasing hormone, adrenocorticotropic hormone, and cortisol, many other neuroendocrine factors participate in the regulation of HPA stress response. The HPA response to acute and chronic illness exerts a biphasic profile. Tissue corticosteroid resistance may also play an important role. All of these add to the complexity of the concept of 'relative adrenal insufficiency' and may account for the difficulty of clinical diagnosis and for the conflicting results of corticosteroid replacement therapy in severe sepsis/septic shock. The study by Lesur and colleagues expands our understanding of the mechanism, and further study of HPA stress response is warranted.

S Peaking between the K Nown and the U Nknown

One of the things for which Donald Rumsfeld will be remembered is his distinction between ‘known knowns’, ‘known unknowns’ and ‘unknown unknowns’. He was speaking in 2002, at a press conference where he was commenting on the absence of evidence linking the government of Iraq with the supply of weapons of mass destruction to terrorist groups: There are known knowns; there are things we know that...

“Known Knowns, Known Unknowns, & Unknown Unknowns”: Computational Science challenges for analysis of multi-dimensional DNA matrices in Evolutionary & Population Genomics

The advent of so-called NextGen DNA sequencing methods has massively increased the rate at which DNA sequence information can be generated, and the volume and complexity of the data matrices that apply to biological questions, including molecular and organismal evolution and population biology. One such approach is the analysis of complete mitochondrial DNA (mtDNA) genomes from multiple species...

In February 2002, Donald Rumsfeld, the then US Secretary of State for Defence, stated at a Defence Department briefing: ‘There are known knowns. There are things we know that we know. There are known unknowns. That is to say, there are things that we now know we don’t know. But there are also unknown unknowns. There are things we do not know we don’t know.’ As a result, he was almost universall...
