Retinal cell transplantation in retinitis pigmentosa
Taiwan Journal of Ophthalmology, 2021 Retinitis pigmentosa is the most common hereditary retinal disease. Dietary supplements, neuroprotective agents, cytokines, and lately, prosthetic devices, gene therapy, and optogenetics have been employed to slow down the retinal degeneration or improve light perception.

Retinitis pigmentosa and retinal oedema. [PDF]
British Journal of Ophthalmology, 1978 Twenty-five patients with retinitis pigmentosa and retinal leakage were investigated. Oedema was present in dominant and X-linked inherited disease and is likely to be present in recessive disease as well. We suggest that this might be a general response seen in many types of tapeto-retinal degeneration to actively degenerating photoreceptors or ...

The Root Clock as a Signal Integrator System: Ensuring Balance for Survival
Frontiers in Plant Science, 2022 The root system is essential for the survival of terrestrial plants, plant development, and adaptation to changing environments. The development of the root system relies on post-embryonic organogenesis and more specifically on the formation and growth ...

Mathematical Biosciences and Engineering, 2021 The purpose of this manuscript was to design a better method for recovery from rhegmatogenous retinal detachment (RRD) surgery. We attempted to achieve this by designing a helmet that can manipulate intraocular magnetic nanoparticles (MNPs) and create a ...

IEEE Transactions on Biomedical Engineering, 2012 Retinal prosthesis has been translated from the laboratory to the clinic over the past two decades. Currently, two devices have regulatory approval for the treatment of retinitis pigmentosa. These devices provide partial sight restoration and patients use this improved vision in their everyday lives.

Retinal imaging in inherited retinal diseases [PDF]
Annals of Eye Science, 2020 Inherited retinal diseases (IRD) are a leading cause of blindness in the working age population. The advances in ocular genetics, retinal imaging and molecular biology, have conspired to create the ideal environment for establishing treatments for IRD, with the first approved gene therapy and the commencement of multiple therapy trials.

Crystal Structure of the N112A Mutant of the Light-Driven Sodium Pump KR2
Crystals, 2020 The light-driven sodium pump KR2, found in 2013 in the marine bacteria Krokinobacter eikastus, serves as a model protein for the studies of the sodium-pumping microbial rhodopsins (NaRs). KR2 possesses a unique NDQ (N112, D116, and Q123) set of the amino
