  • SYSTEMS AND METHODS FOR CAPTURING, ANNOTATING AND SHARING OPHTHALMIC IMAGES OBTAINED USING A HAND HELD COMPUTER
    Publication number: 20210290056
    Abstract: Computer readable code adapted and configured to enable collection, annotation and sharing of digital ophthalmic images collected using a camera module on a mobile device or a hand held computer. The hand held computer can be used with a lens adapter configured to engage with a hand held computer device to allow a camera on the hand held computer device to take a high quality image of an eye.

  • IMMORTALIZED CELL LINES AND METHODS OF USE
    Publication number: 20200179507
    Abstract: Provided herein is a non-natural isolated chicken fibroblast cell that has the characteristics of immortalized growth and supporting replication of Marek's Disease Virus (MDV), wherein number of MDV produced by the cell is at least 1.5-fold greater than the number of the same MDV produced by a DF-1 cell under the same conditions. Also provided herein are methods including producing virus using the cell, determining the number of virus in a sample using the cell, and using the cell to produce protein.

  • Method for immortalizing chicken cells
    Patent number: 5830723
    Abstract: This invention relates to the introduction of p53 under the control of the metallothionein promoter into primary cells to produce immortalized cell lines. The cells are useful as substrates for viral propagation, as contaminant-free sources for recombinant protein production, for recombinant virus production and as cell substrates to support primary cells and improve virus yield during virus propagation.
