Researchers identify unique circadian rhythm photoreceptor

...ding to Rosbash, applying findings about circadian photosensitivity in fruit flies to mammals is currently problematic because a mammalian circadian photoreceptor has not yet been identified. Mammalian cryptochrome molecules appear to be involved in the central clockwork mechanism, rather than in light-detection, he ...

Aslera™ improves lupus disease activity and symptoms

...ache, muscle weakness, memory loss, hair loss, and photosensitivity - can lead to a poor quality of life. Lupus can be mild but also can cause significant and potentially serious damage to organs such as the lungs, heart, kidney, and brain. The disease is characterized by flares of disease activity interspersed with...

Molecule helps pupils respond to light

...animal could be directly attributed to the loss of photosensitivity of these retinal ganglion cells rather than to elusive causes such as mis-wiring in the circuitry," said Yau. To determine the physiological effect of the melanopsin-deficient cells, the researchers chose to measure how the pupils of the knockout mic...
