In the current study , a comprehensive , data driven , mathematical model for cholera transmission in Haiti is presented . Along with the inclusion of short cycle human-to-human transmission and long cycle human-to-environment and environment-to-human transmission , this novel dynamic model incorporates both the report... | Based on the model-fitted trend and the observed incidence , there is evidence that after an initial period of intense transmission , the cholera epidemic in Haiti stabilized during the third year of the outbreak and became endemic .

The Rhox cluster on the mouse X chromosome contains reproduction-related homeobox genes expressed in a sexually dimorphic manner . We report that two members of the Rhox cluster , Rhox6 and 9 , are regulated by de-methylation of histone H3 at lysine 27 by KDM6A , a histone demethylase with female-biased expression . Co... | Homeobox ( HOX ) genes are known to be under epigenetic control during development .
