Circadian regulation of reproduction and neoblast cell division in the catenulid flatworm Stenostomum virginianum (Platyhelminthes)

Photochemistry and Photobiology, EarlyView.
The circadian clock and melatonin coordinate homeostasis in many animals, yet their influence on reproduction and neoblast proliferation has only been shown in triclads. This study demonstrates that the early‐branching catenulid Stenostomum virginianum contains photoreceptive refractile bodies, synthesizes endogenous melatonin, and that exogenous ...

The effects of spectrum, irradiance, and duration of exposure on light‐induced melatonin suppression in healthy adults

Photochemistry and Photobiology, EarlyView.
The left panel reports the measured time course data of melatonin concentration in the blood plasma of 17 BL‐Rs and 15 BL‐NRs at baseline, during a two‐hour stay in the dark, during a one‐hour light exposure to blue light, and again in the dark. The right panel shows the magnitude of melatonin concentration after 60 min of exposure to warm white, cool ...

Photochemistry of CryB from Rhodobacter sphaeroides

Photochemistry and Photobiology, EarlyView.
Elucidation of the photochemistry of CryB from Rhodobacter sphaeroides was achieved from the nanosecond to second timescale. A fast (<5 ns) deprotonation of the terminal electron donor Trp338 and the involvement of Tyr337 in photoreduction have been revealed.
