Patent number: 11873515Abstract: The present invention provides a dehydrogenase mutant L283V/L286V, and a preparation method and use thereof, and relates to the field of biomedicine technologies. An amino acid sequence of the mutant L283V/L286V is as shown in SEQ ID NO: 1; and the mutant is prepared by simultaneously mutating 283rd and 286th leucine of a dehydrogenase with an amino acid sequence as shown in SEQ ID NO: 3 into valine. The dehydrogenase mutant L283V/L286V shows high selectivity in catalyzing myosmine reduction reaction in a whole cell system to produce S-nornicotine, and has relatively high dehydrogenase and imine reductase activities, a short enzyme reduction time, and a high transformation rate. The product S-nornicotine obtained through the reaction has extremely high optical purity, which reduces the operation difficulty of subsequent purification.Type: GrantFiled: November 18, 2022Date of Patent: January 16, 2024Assignees: GOLDEN HEALTH (GUANGDONG) BIOTECHNOLOGY CO., LTD., TF BIOSYN BIOTECHNOLOGY CO., LTD.Inventors: Jiajun Huang, Rongxu Li, Ziying Wu, Haoxuan Hu, Shaoyu Bai, David Zhou, Tony Lu

Patent number: 10220202Abstract: A flexible circuit electrode array with more than one layer of metal traces comprising: a polymer base layer; more than one layer of metal traces, separated by polymer layers, deposited on the polymer base layer, including electrodes suitable to stimulate neural tissue; and a polymer top layer deposited on the polymer base layer and the metal traces. Polymer materials are useful as electrode array bodies for neural stimulation. They are particularly useful for retinal stimulation to create artificial vision, cochlear stimulation to create artificial hearing, or cortical stimulation many purposes. The pressure applied against the retina, or other neural tissue, by an electrode array is critical. Too little pressure causes increased electrical resistance, along with electric field dispersion. Too much pressure may block blood flow.Type: GrantFiled: May 2, 2017Date of Patent: March 5, 2019Assignee: Second Sight Medical Products, Inc.Inventors: Jordan Neysmith, Robert Greenberg, James Little, Brian Mech, Neil Talbot, Qingfang Yao, David Zhou
