Low iron. binds to 3 prime of transferin receptor mRNA= increased levels of transferin receptor mRNA that is translated to increase levels of transferin receptors on cell surface to facilitate iron uptake by the cell.

The diffusion of influenza in sub-Saharan Africa during the 1918-1919 pandemic. Patterson KD, Pyle GF. The focus of this study is the spread of influenza in Africa south of the Sahara during the pandemic of 1918-1919. Most known types of diffusion pattern, i.e. radial, wave-like and linear, have been identified; however, the disease spread to rapidly that four particularly devastating linear patterns stand out. One of the most incredible aspects of the regularity in epidemic velocity along these pathways was that the colonial transportation network was of fairly recent origin.
