In response to the anthropogenic assault of toxic baits, populations of the German cockroach have rapidly evolved an adaptive behavioral aversion to glucose (a phagostimulant component of baits). We hypothesized that changes in the peripheral gustatory system are responsible for...

Effect of smoking and caffeine consumption (CC) on the levels of polybrominated diphenyl ethers (PBDE) and polybrominated biphenyls (PBB) has not been adequately studied. Data from 2003-2004 National Health and Nutrition Examination Survey (n = 1013) to simultaneously evaluate the...

There is a high interindividual variability in cytochrome P4501A2 (CYP1A2) activity and in its inducibility by smoking, only poorly explained by known CYP1A2 polymorphisms. We aimed to study the contribution of other regulatory pathways, including transcription factors and nuclear receptors...

Machado-Joseph disease (MJD) is a neurodegenerative disorder associated with an abnormal CAG expansion, which translates into an expanded polyglutamine tract within ataxin-3. There is no therapy to prevent or modify disease progression. Because caffeine (a nonselective adenosine receptor antagonist) and...
