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 […]
by Jason Rainbow — May 25, 2021 TAMPA, Fla. — Satellite operator Viasat is asking the FCC to stop SpaceX from launching more Starlink satellites as it heads to court to compel a thorough environmental review of the rapidly growing megaconstellation. On Friday, Viasat formally asked the Federal Communications Commission to stay an April 27 license modification that allows SpaceX […]
Environmental Factors-Induced Oxidative Stress: Hormonal and Molecular Pathway Disruptions in Hypogonadism and Erectile Dysfunction Abstract Hypogonadism is an endocrine disorder characterized by inadequate serum testosterone production by the Leydig cells of the testis. It is triggered by alterations in the hypothalamic–pituitary–gonadal axis. Erectile dysfunction (ED) is another common disorder in men that involves an alteration […]
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 […]
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 […]
