Interconnection between circadian clocks and thyroid function

June 13, 2021
Ikegami, K., Refetoff, S., Van Cauter, E. et al. Interconnection between circadian clocks and thyroid function. Nat Rev Endocrinol 15, 590–600 (2019). https://doi.org/10.1038/s41574-019-0237-z Abstract Circadian rhythmicity is an approximately 24-h cell-autonomous period driven by transcription–translation feedback loops of specific genes, which are referred to as ‘circadian clock genes’. In mammals, the central circadian pacemaker, which is located in the hypothalamic...

Medical hypothesis: Light at night is a factor worth considering in critical care units

June 11, 2021
Nelson RJ, DeVries AC. Medical hypothesis: Light at night is a factor worth considering in critical care units. Adv Integr Med. 2017;4(3):115-120. doi:10.1016/j.aimed.2017.12.001 Abstract Exposure to light at night is not an innocuous consequence of modernization. There are compelling data linking long-term exposure to occupational and environmental light at night with serious health conditions, including heart...

Seeing the light: beneficial impacts on neuroendocrine physiology?

May 26, 2021,
British Society for Neuroendocrinology Briefing 58 Dr Manuel Spitschan In addition to seeing the colourful and detailed world around us, light profoundly impacts our brains and bodies – exposure to light in the evening and at night suppresses the production of melatonin and disrupts our circadian rhythm, which can have negative consequences on physical and...

Partial recovery of visual function in a blind patient after optogenetic therapy

May 24, 2021
Sahel, JA., Boulanger-Scemama, E., Pagot, C. et al. Partial recovery of visual function in a blind patient after optogenetic therapy. Nat Med (2021). https://doi.org/10.1038/s41591-021-01351-4 Abstract Optogenetics may enable mutation-independent, circuit-specific restoration of neuronal function in neurological diseases. Retinitis pigmentosa is a neurodegenerative eye disease where loss of photoreceptors can lead to complete blindness. In a blind patient, we combined...

For the First Time, Optogenetic Therapy Partially Restores Patient’s Vision

May 24, 2021
Source https://www.pittwire.pitt.edu/news/first-time-optogenetic-therapy-partially-restores-patient-s-vision Optogenetic therapy, or manipulating proteins and cells with light, is an advanced technology developed in the early 2000s that drove major discoveries about the inner workings of our brains. Yet, while actively researched in experimental animals, functional improvement using this method was never reported in humans—until now. In a paper published today in Nature...
