Microarray is a technique that provides a global analysis of gene expression at the level of transcription. Genetic and epigenetic changes underlie neoplastic transformation, cardiovascular disease, some psychiatric illnesses, and a growing list of disease pathogeneses and therapeutic responses. The profile of genes expressed by different cells (gene up- and downregulation under different conditions) determines their phenotype, and thus provides insights into the molecular basis for health and disease.

Genome-wide association aims to comprehensively survey genetic variation for the purposes of disease and trait mapping. We provide a brief history of the development of genetic technology necessary to realize genome-wide association. From there we identify and review the publicly available resources for conducting such work including the molecular technologies, genomic databases, and analytic tools. Following on from the analytic tools, we highlight common analytic considerations, ranging from study design, quality control, and data cleaning to association analysis and replication.

Palicourea coriacea, popularly known as "douradinha", is a medicinal plant from the Brazilian Cerrado region used in folk medicine to treat kidney and urethral stones and kidney inflammation. We evaluated the cytotoxic, genotoxic, and possible antigenotoxic activities of an aqueous extract of P. coriacea on somatic cells of Drosophila melanogaster, using the somatic mutation and recombination test. We used third-stage larvae of D. melanogaster from a standard cross and a high bioactivation cross and tested 10 different doses of P.
