Crosstalk between prolactin, insulin-like growth factors, and thyroid hormones in feather growth regulation in neonatal chick wings.

The elongation of primary feathers in neonatal chicks is delayed by the late-feathering K gene located on the Z chromosome. We recently found that the K gene slows feather growth by reducing the number of functional prolactin (PRL) receptor (PRLR) dimers. In this study, we investigated the molecular mechanisms by which PRL promotes feather elongation.

Association of family meals with sleep and quality of life in Japanese preschool and elementary school children: A cross-sectional study.

Sleep is crucial for children's health and eating habits. The decline in family meals has raised concerns about its impact on children. Previous research indicated associations between family meals and psychological health and dietary habits, but their relationship with sleep behavior is less understood.
