TL;DR: It is indicated that greater consumption of dairy products over a 12-week period does not change rectal mucosal cell proliferation, and measures of the location and intensity of cell proliferation within the rectal crypt were highly correlated between the two assays.

TL;DR: Oral contraceptive use was associated with an increased risk of SCC and BCC, and both OC use and combination HRT use were associated with more aggressive BCC subtypes, providing evidence that use of sex steroids may enhance risk of keratinocyte cancer.

TL;DR: The results reveal multiple biological functions in the fetal placenta that are potentially affected by increased arsenic exposure, a subset of which is sex-dependent and suggest that in female infants, the mechanisms underlying the arsenic-induced reduction of birth weight may involve activation of stress response pathways.

TL;DR: GLI3 is identified as a key signaling node that is affected by arsenic, mediating a subset of its effects on developmental signaling and fetal health.

TL;DR: In linear mixed models adjusting for maternal and child characteristics, maternal urinary Cd levels were not significantly associated with cognitive function at ages 1, 2, 3, 5, and 8 years or with behavioral composite measures in children at 1-8 years of age.
