Sex-specific DNA methylation and associations with tobacco smoke exposure at nuclear-encoded mitochondrial genes.

Sex-linked differences in mitochondrial ATP production, enzyme activities, and reactive oxygen species generation have been reported in multiple tissue and cell types. While the effects of reproductive hormones underlie many of these differences, regulation of sexually dimorphic mitochondrial function has not been fully characterized. We hypothesized that sex-specific DNA methylation contributes to sex-specific expression of nuclear genes that influence mitochondrial function.

Student Perceptions of a University Medical Amnesty Policy Are Impacted by Race and Racism: A Qualitative Study.

Alcohol consumption on college and university campuses is a public health concern. Some universities have instituted medical amnesty policies (MAPs) to encourage calling first responders to the scene of an alcohol-related emergency. This study describes perceptions of a university MAP and the perceived risks of calling first responders among a sample of undergraduate students at a mid-sized, private, residential university.
