Year-long use of a typical antiviral treatment for shingles was particularly impactful in reducing complications when the condition eventually affected the eye
Working with mammalian retinal cells, neuroscientists at Johns Hopkins Medicine have shown that, unlike most light-sensing cells (photoreceptors) in the retina, one special type uses two different pathways at the same time to transmit electrical “vision” signals to the brain.
A Johns Hopkins Children’s Center study of children and youth with diabetes concludes that so-called autonomous artificial intelligence (AI) diabetic eye exams significantly increase completion rates of screenings designed to prevent potentially blinding diabetes eye diseases (DED).
Researchers at the University of California San Diego have developed a neural implant that provides information about activity deep inside the brain while sitting on its surface.
Scientists at the Johns Hopkins University School of Medicine and the National Institutes of Health have identified a protein in the visual system of mice that appears to be key for stabilizing the body’s circadian rhythms by buffering the brain’s response to light.
Relatively short-term use of immunosuppressant medications to control an inflammatory disease was not associated with an increased risk of later developing cancer, according to new research.
Researchers at Vanderbilt University Medical Center have received a four-year, $28 million grant from the National Institute of Diabetes and Digestive and Kidney Diseases, part of the National Institutes of Health, to study the relationship between COVID-19 and diabetes.
People with diabetes who experience periods of low blood sugar — a common occurrence in those new to blood sugar management — are more likely to have worsening diabetic eye disease. Now, researchers at Johns Hopkins Medicine say they have linked such low blood sugar levels with a molecular pathway that is turned on in oxygen-starved cells in the eye.
National Eye Institute researchers mapped the organization of human retinal cell chromatin, the fibers that package 3 billion nucleotide-long DNA molecules into compact structures that fit into chromosomes within each cell’s nucleus. The resulting comprehensive gene regulatory network provides insights into regulation of gene expression in general, and in retinal function, in both rare and common eye diseases. The study published in Nature Communications.
Black patients have a dramatically higher risk of advanced vision loss after a new diagnosis of primary open angle glaucoma (POAG) when compared to white patients, according to a new study from New York Eye and Ear Infirmary of Mount Sinai (NYEE).
Johns Hopkins Medicine researchers have developed a color-coded test that quickly signals whether newly developed nanoparticles — ultra small compartments designed to ferry medicines, vaccines and other therapies — deliver their cargo into target cells. The new testing tool, engineered specifically to test nanoparticles, could advance the search for next-generation biological medicines.
Researchers at Washington University School of Medicine in St. Louis have received two grants from the National Institutes of Health (NIH) totaling more than $5.5 million to develop new treatments for two types of devastating parasitic infections common in sub-Saharan Africa and Central and South America: river blindness and intestinal worm infections.
Scientists have discovered that gene therapy and the diabetes drug metformin may be potential treatments for late-onset retinal degeneration (L-ORD), a rare, blinding eye disease. Researchers from the National Eye Institute (NEI), part of the National Institutes of Health generated a “disease-in-a-dish” model to study the disease. The findings are published in Communications Biology.
As regenerative therapies for blinding diseases move closer to clinical trials, the National Eye Institute’s functional imaging consortium, a part of the NEI Audacious Goals Initiative (AGI), is pioneering noninvasive technologies to monitor the function of the retina’s light-sensing neurons and their connections to the brain.
Researchers at the University of Illinois Chicago have been awarded a five-year, $10.15 million grant to develop a broad-spectrum immunomodulatory eye drop.
A high-sugar diet creates a ‘double jeopardy’ impact for a protein crucial to cellular housekeeping, a new study suggests. The protein offsets cell damage from sugar, but too much sugar renders it ineffective. The results may offer insight for reducing age-related degenerative disease.
Shantanu Chakrabartty’s laboratory has been working to create sensors that can run on the least amount of energy. His lab has been so successful at building smaller and more efficient sensors, that they’ve run into a roadblock in the form of a fundamental law of physics.Sometimes, however, when you hit what appears to be an impenetrable roadblock, you just have to turn to quantum physics and tunnel through it.
The NIH grant will enable FAU scientists to identify the gene regulation pathways activated to program immature stem-like cells of the eye lens to attain their mature form and transparent function. The research team plans to explore the genetic and cellular mechanisms controlling developmental DNA conformational changes and will identify the transcription factors needed for eye lens formation.
