research Telogen elongation in the hair cycle of ob/ob mice
Obese mice with a leptin gene mutation have a longer resting phase in their hair cycle, which may help understand certain hair loss conditions.
research Murine skin as a target for melatonin bioregulation
Melatonin affects mouse skin and may regulate skin functions.
research Dynamic spatiotemporal coordination of neural stem cell fate decisions through local feedback in the adult vertebrate brain
Neural stem cells use local feedback to maintain balance in the adult brain.
research Highlights from the Literature
Apoptosis, not oxidative stress, is linked to aging in mice with mtDNA mutations.
research The effect of melatonin implants administered from December until April, on plasma prolactin, triiodothyronine and thyroxine concentrations and on the timing of the spring moult in cashmere goats
Melatonin implants can change the seasonal prolactin levels and hair growth in adult cashmere goats but not in juveniles, and don't delay spring moult for better fiber harvesting.
research The Neuroscience of Age Perception
Humans can accurately guess age from faces, with women being slightly better at it, and age perception is linked to evolutionary factors.
research Transcriptome Dynamics Reveal Stage-specific and Melatonin-triggered Gene Expression Patterns During the Cashmere Growth Cycle in Capra Hircus
Melatonin can increase cashmere yield by altering gene expression and restarting the growth cycle early.
