The effectiveness of insecticide-treated nets in preventing malaria is threatened by developing resistance against pyrethroids. Little is known about how strongly this affects the effectiveness of vector control programmes. Data from experimental hut studies on the effects of long-lasting, insecticidal

Disruptive epigenetic gene control has been shown to be involved in carcinogenesis. To identify key molecules in piperonyl butoxide (PBO)-induced hepatocarcinogenesis, we searched hypermethylated genes using CpG island (CGI) microarrays in non-neoplastic liver cells as a source of proliferative lesions
