Good news when it comes to eyesight involving corneal transplantation. A new approach in ophthalmology that offers a revolutionary alternative to corneal transplantation has just been developed by researchers and clinicians in North America, Europe, and Oceania. The research, which was co-led by May Griffith, a researcher at Maisonneuve-Rosemont Hospital Research Centre, discovered a synthetic, biocompatible and adhesive liquid hydrogel, LiQD Cornea, is applied as a liquid, but quickly adheres and gels within the corneal tissue. The LiQD Cornea promotes tissue regeneration, thus treating the corneal perforations. “Our work has led to an effective and accessible solution called LiQD Cornea to treat corneal perforations without the need for transplantation,” said Griffith.
How Harmful Exactly Are Tobacco Cigarettes, E-Cigarettes, and Waterpipe Smoking
A new study led by Dr. Thomas Munzel, chief of cardiology at the University Medical Center at Johannes Gutenberg University in Mainz, Germany, is said to be the first major one of its kind to compare the three forms of smoking and vaping: tobacco, e-cigarettes, and water pipes. The study says that, while e-cigarette vapour is less toxic than tobacco smoke, smoking and vaping both stiffen arteries, cause inflammation, damage DNA, as well as increase the risk of serious COVID-19 complications. The full study can be found on the European Heart Journal website, study no -ehaa460.
Declining Eyesight Improved by Looking at Deep Red Light
Staring at a deep red light for three minutes a day can significantly improve declining eyesight, finds a new UCL-led study, the first of its kind in humans. Scientists believe the discovery, published in the Journals of Gerontology, could signal the dawn of new affordable home-based eye therapies, helping the millions of people globally with naturally declining vision.
Research Find Out Why Some Words May Be More Memorable Than Others
Thousands of words, big and small, are crammed inside our memory banks just waiting to be swiftly withdrawn and strung into sentences. In a recent study of epilepsy patients and healthy volunteers, National Institutes of Health researchers found that our brains may withdraw some common words, like “pig,” “tank,” and “door,” much more often than others, including “cat,” “street,” and “stair.” By combining memory tests, brain wave recordings, and surveys of billions of words published in books, news articles and internet encyclopaedia pages, the researchers not only showed how our brains may recall words but also memories of our past experiences. The team is currently exploring ways to incorporate their results and computer model into the development of memory tests for Alzheimer’s disease and other forms of dementia
