Low academic accomplishment in children is usually a common and significant problem that affects 10-20 percent of the populace. Short or poor sleep is a substantial risk factor for poor academic overall performance that is frequently ignored, says Gruber, who is a researcher at the Douglas Institute and professor in McGill's Department of Psychiatry. Gruber's research group, in collaboration with the Riverside College Board in Saint-Hubert, Quebec, studied 75 healthy children between 7 and 11 years.This chemical substance in turn altered DNA, generating an irregular, mutagenic DNA base called a Cr-PdG adduct. Dr. Brooks says, ‘We concluded that polyamines stimulated the forming of Cr-PdG adducts from acetaldehyde, and this might provide a mechanism to explain how alcohol consumption increases the threat of some types of malignancy.’ Related StoriesNew antenna-like device makes breast cancer medical procedures less complicated for surgeonsSausages With Antioxidants From Berries TO AVOID CancerNew results reveal association between colorectal tumor and melanoma medication treatmentPrevious studies had demonstrated acetaldehyde could be changed into mutagenic Cr-PdG, but those studies used high acetaldehyde concentrations.
