Rats on 22.5‐Hr Light:Dark Cycles Have Vaginal Opening Earlier Than Rats on 26‐Hr Light:Dark Cycles
@article{Lehrer1986RatsO2, title={Rats on 22.5‐Hr Light:Dark Cycles Have Vaginal Opening Earlier Than Rats on 26‐Hr Light:Dark Cycles}, author={S Lehrer}, journal={Journal of Pineal Research}, year={1986}, volume={3} }
Rats on 22.5‐hr light:dark cycles had vaginal opening significantly earlier than rats on 26‐hr light:dark cycles. This finding might explain the early menarche in blind girls: Their circadian rhythms, like those of rats on 22.5‐hr cycles, might be more rapid than normal. Thus a set number of cycles can occur in a shorter time than usual, allowing puberty to take place early.

Mechanism of programmed obesity: altered central insulin sensitivity in growth-restricted juvenile female rats
- Biology, MedicineJournal of Developmental Origins of Health and Disease
- 2013
Despite feeding, IUGR offspring exhibit a persistent state of orexigenic stimulation in the ARC nucleus and relative resistance to the anorexigenic effects of icv insulin, which suggest that impaired insulin signaling contributes to hyperphagia and obesity in IugR offspring.
