Abstract Background Sporadic hepatitis E has become an important public health concern in China. Accurate forecasting of the incidence is needed to better plan future medical needs. Few mathematical models can be used because morbidity data both linear and nonlinear patterns. We developed a combined model using autoregressive integrated moving average (ARIMA) back propagation neural network (BPNN) forecast E. Methods The Shanghai from 2000 2012 were retrieved China Information System for...

The number of litters is an important reproductive trait, which one the main indicators reflecting production level and economic benefit pig farm. As organ female mammals, ovary controlled by a complex transcription network coding non-coding genes to undergo series biological processes during each estrus cycle, thereby regulating capacity sow. However, these molecular regulation mechanisms affecting sow litter size are still unclear. Regarding regulatory in ovarian function with smaller...
