Versatile Cataract Fundus Image Restoration Model Utilizing Unpaired Cataract and High-quality Images [PDF]
arXivCataract is one of the most common blinding eye diseases and can be treated by surgery. However, because cataract patients may also suffer from other blinding eye diseases, ophthalmologists must diagnose them before surgery. The cloudy lens of cataract patients forms a hazy degeneration in the fundus images, making it challenging to observe the patient'

Cataract and surgery for cataract [PDF]
BMJ, 2006 Cataract surgery is the commonest single surgical procedure carried out in the developed world. In the developing world, cataract remains the commonest cause of blindness. In 1990 an estimated 37 million people were blind worldwide—40% of them because of cataract.1 Every year, an extra 1-2 million people go blind.

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 450-457, December 2022., 2022 Abstract We evaluated the performance of five commercial microstarter diets (Otohime, Gemma Micro, Gemma Wean, Optimal Starter, and Omega One Fry) fed to first feeding larval saugeye Sander vitreus × Sander canadensis. Triplicate tanks of 2500 larvae (initial weight: 2.6 ± 0.6 mg) were stocked at 4 days post‐hatch (DPH) and fed treatment diets for 4 ...

Clinical overview on RASopathies
American Journal of Medical Genetics Part C: Seminars in Medical Genetics, Volume 190, Issue 4, Page 414-424, December 2022., 2022 Abstract RASopathies comprise a group of clinically overlapping developmental disorders caused by genetic variations affecting components or modulators of the RAS‐MAPK signaling cascade, which lead to dysregulation of signal flow through this pathway.

An Annotation-free Restoration Network for Cataractous Fundus Images [PDF]
IEEE Transactions on Medical Imaging,2022, 41(7), 1699-1710, 2022 Cataracts are the leading cause of vision loss worldwide. Restoration algorithms are developed to improve the readability of cataract fundus images in order to increase the certainty in diagnosis and treatment for cataract patients. Unfortunately, the requirement of annotation limits the application of these algorithms in clinics. This paper proposes a
