The effect of melatonin on the number of synaptic ribbons (SR) in the pineal photoreceptor cells was examined in the Japanese newt using electron microscopy. Under a light-dark cycle of LD 12:12 (lights on at 07:00), a subcutaneous injection of 10 microg of melatonin at two times during the day (at 11:00 and 11:30) did not increase the number of SR.(More)
BACKGROUND Doublecortin and calcium/calmodulin-dependent protein kinase-like-1 (DCAMKL1) is a candidate marker for progenitor cells in the gastrointestinal mucosa. Lineage cells in the gastric mucosa are derived from progenitor cells, but this process can be altered after injury. Therefore, we explored DCAMKL1 expression under pathological conditions. (More)
The circadian locomotor activity rhythm of the Japanese newt has been thought to be driven by a putative brain oscillator(s) subordinate to the pineal clock. The existence of mutual coupling between the pineal clock and the brain oscillator(s) in vivo was examined. We covered the newt's skull with aluminum foil and simultaneously reversed the light-dark(More)
