PKB/Akt and serum and glucocorticoid–regulated kinase (SGK) family kinases are important downstream targets of phosphatidylinositol 3 (PI-3) kinase and have been shown to mediate a variety of...
Confidence intervals for predicted outcomes in regression models for categorical outcomes
We discuss methods for computing confidence intervals for predictions and discrete changes in predictions for regression models for categorical outcomes. The methods include endpoint transformation,...

Fungi in the genus Malassezia are ubiquitous skin residents of humans and other warm-blooded animals. Malassezia are involved in disorders including dandruff and seborrheic dermatitis, which together...
Sex-Specific Expression of the X-Linked Histone Demethylase Gene Jarid1c in Brain
Xu, Jun, Deng, Xinxian, Disteche, Christine M.
Jarid1c, an X-linked gene coding for a histone demethylase, plays an important role in brain development and function. Notably, JARID1C mutations cause mental retardation and increased aggression in...

Two Cap-Binding Proteins CBP20 and CBP80 are Involved in Processing Primary MicroRNAs
Kim, Sanghee, Yang, Jun-Yi, Xu, Jun, Jang, In-Cheol, Prigge, Michael J., Chua, Nam-Hai
MicroRNAs (miRNAs) are 21 nt RNAs that regulate many biological processes in plants by mediating translational inhibition or cleavage of target transcripts. Arabidopsis mutants defective in miRNA...
