Publication number: 20240238444Abstract: Provided is a composition for the prevention or treatment of Hutchinson-Gilford Progeria syndrome (HGPS) using gene editing, which contains sgRNA that hybridizes to mRNA encoding progerin, which causes HGPS, and a gene encoding Cas13 protein acting on the same. When introduced into the cell of a subject to be treated and only the mRNA encoding progerin is selectively cut. There is no need for co-prescribing with other therapies and fewer side effects occur than traditional farnesyltransferase inhibitors (FTIs). The efficiency is higher than when treated using homologous recombination (HR) at the DNA level, treatment using composition can be made reversibly, and the composition can be applied specifically compared to targeted treatment using RNAi (RNA interference), and has fewer side effects. Compared to treatment using CRISPR/Cas9, which directly acts on DNA and produces irreversible results, treatment using composition is reversible and selectively cut only mRNA encoding progerin, thereby ensuring safety.Type: ApplicationFiled: May 2, 2023Publication date: July 18, 2024Applicant: KOREA RESEARCH INSTITUTE OF BIOSCIENCE AND BIOTECHNOLOGYInventors: Sun Uk KIM, Young Ho PARK, Seung Hwan LEE, Jong Hee LEE, Jae Jin CHA, Han Seop KIM, Un Bin CHAE

Patent number: 11144814Abstract: Structure defect detection is performed using computer-implemented arrangements employing machine learning algorithms in the form of neural networks. In one arrangement, a convolutional neural network is trained using a database of images formed to optimize accuracy of the convolutional neural network to detect, for example, a crack in a concrete surface. A two-stage scanning process each performing a plurality of scans of a test image is incorporated in the foregoing arrangement of convolutional neural network, with the two-stages forming overlapping capture areas to reduce likelihood of a crack lying on a boundary of the individual scans going undetected. Also, region-based convolutional neural networks are trained to detect various types of defects.Type: GrantFiled: September 13, 2019Date of Patent: October 12, 2021Inventors: Young Jin Cha, Wooram Choi
