Publication number: 20240100148Abstract: Provided herein are non-naturally occurring, broadly reactive antigens derived from influenza viruses that are immunogenic and capable of eliciting a broadly reactive immune response, e.g., a broadly reactive neutralizing antibody response, directed against influenza virus antigens following introduction into a subject. Also provided are non-naturally, broadly reactive immunogens, vaccines, virus particles, virus-like particles (VLPs) and compositions comprising the immunogens and vaccines. Methods of generating an immune response in a human or non-human subject by administering the immunogens, vaccines, VLPs, or compositions thereof are provided. In particular, the immunogens comprise broadly reactive hemagglutinin (HA) protein antigens or soluble HA protein antigens of influenza virus strains, such as H1 or H3.Type: ApplicationFiled: December 4, 2023Publication date: March 28, 2024Applicant: University of Georgia Research Foundation, Inc.Inventors: Ted M.

Patent number: 10712357Abstract: Disclosed are apparatus and methods that provide the ability to electrical stimulate a physical system, and actively eliminate interference with signal acquisition (artifacts) that arises from the stimulation. The technique implemented in the circuits and methods for eliminating interference connects a discharge path to a physical interface to the system to remove charge that is built-up during stimulation. By placing the discharge path in a feedback loop that includes a recording preamplifier and AC-coupling circuitry, the physical interface is brought back to its pre-stimulation offset voltage. The disclosed apparatus and methods may be used with piezoelectric transducers, ultrasound devices, optical diodes, and polarizable and non-polarizable electrodes. The disclosed apparatus can be employed in implantable devices, in vitro or in vivo setups with vertebrate and invertebrate neural tissue, muscle fibers, pancreatic islet cells, osteoblasts, osteoclasts, bacteria, algae, fungi, protists, and plants.Type: GrantFiled: June 15, 2017Date of Patent: July 14, 2020Assignee: Georgia Tech Research CorporationInventors: Edgar A.
