Gene expression findings a step toward better classification and treatment of juvenile arthritis

Scientists have discovered gene expression differences that could lead to better ways to classify, predict outcome, and treat juvenile idiopathic arthritis (JIA). Eventually such findings could enable doctors to target more aggressive treatment to children at risk of more severe arthritis, while t...

New understanding of COX-1 and COX-2 enzymes could revise classification of pain meds

An entropy-based gene selection method for cancer classification using microarray data

Accurate diagnosis of cancer subtypes remains a challenging problem. Building classifiers based on gene expression data is a promising approach; yet the selection of non-redundant but relevant genes is difficult.
