Genetic linkage maps have been constructed for the rice and maize genomes on basis of orthologous loci detected with a common set cDNA clones. Conserved groups could be identified, which together account more than two-thirds both genomes. In some instances, entire chromosomes or chromosome arms are nearly identical respect to gene order content. The results also reveal that most genes (> 72%) duplicated during ancient polyploidization still present in genome duplicate copy. comparative...

Exposure to valproic acid (VPA) during pregnancy has been linked with increased incidence of autism, and repeatedly demonstrated as a useful autism mouse model. We examined the early behavioral anatomical changes well molecular in mice prenatally exposed VPA (VPA mice). In this study, we first showed that developmental delays assessed self-righting, eye opening tests impaired social recognition. addition, provide evidence primary cultured neurons from VPA-treated embryos present an increase...

Mounting evidence suggests that the etiology of autism spectrum disorders (ASDs) is profoundly influenced by exposure to environmental factors, although precise molecular and cellular links remain ill-defined. In this study, we examined how valproic acid (VPA) during pregnancy associated with an increased incidence ASD. A mouse model was established injecting VPA at embryonic day 13, its behavioral phenotypes including impaired social interaction, repetitive behaviors decreased nociception...

For personalized drug dosing, prediction models may be utilized to overcome the inter-individual variability. Multiple linear regression has been used as a conventional method model relationship between patient features and optimal dose. However, cannot capture non-linear relationships adversely affected by non-normal distribution collinearity of data. To this hurdle, machine learning have extensively adapted in dose prediction. In tutorial, random forest neural network will trained tandem...
