Real Texture for Lab-grown Meat

Technology Networks | October 21, 2019

Lab-grown or cultured meat could revolutionize food production, providing a greener, more sustainable, more ethical alternative to large-scale meat production. But getting lab-grown meat from the petri dish to the dinner plate requires solving several major problems, including how to make large amounts of it and how to make it feel and taste more like real meat. Now, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have grown rabbit and cow muscles cells on edible gelatin scaffolds that mimic the texture and consistency of meat, demonstrating that realistic meat products may eventually be produced without the need to raise and slaughter animals. Kit Parker, the Tarr Family Professor of Bioengineering and Applied Physics at SEAS and senior author of the study, began his foray into food after judging a competition show on the Food Network. "The materials science expertise of the chefs was impressive," said Parker. "After discussions with them, I began to wonder if we could apply all that we knew about regenerative medicine to the design of synthetic foods. After all, everything we have learned about building organs and tissues for regenerative medicine applies to food: healthy cells and healthy scaffolds are the building substrates, the design rules are the same, and the goals are the same: human health. This is our first effort to bring hardcore engineering design and scalable manufacturing to the creation of food."

Biotechnology is a field of applied biology that involves the use of living organisms and bioprocesses in engineering, technology, medicine and other fields requiring bioproducts. The concept encompasses a wide range of procedures for modifying living organisms according to human purposes - going back to domestication of animals, cultivation of plants, and "improvements" to these through breeding programs that employ artificial selection and hybridization.

Ridgeback Biotherapeutics LP Announces the U.S. Food and Drug Administration Approvel of EbangaTM for Ebola

Ebanga | December 29, 2020

Ridgeback Biotherapeutics LP ("Ridgeback"), a biotechnology organization experienced in antiviral drug improvement, reported today that the U.S. Food and Drug Administration ("FDA") approved EbangaTM for the treatment of Ebola. Ebanga is presently affirmed for treatment of disease brought about by Zaire ebolavirus in grown-up and pediatric patients. Ebanga is the only FDA endorsed, single infusion Ebola treatment which is accessible in a lyophilized structure. Wendy Holman, CEO and co-founder of Ridgeback, said: “I speak on behalf of the entire Ridgeback Bio team when I say thank you to all of the dedicated and thoughtful groups who helped contribute to this historic and important product approval. Ridgeback is grateful to NIAID’s Vaccine Research Center (VRC) and the Democratic Republic of the Congo’s (DRC) Institut National pour la Recherche Biomédicale (INRB). Specifically, the brilliance of three individuals needs to be acknowledged -- Dr. Nancy Sullivan (VRC), Dr. John Mascola (VRC) and Professor Jean-Jacques Muyembe-Tamfum (INRB). It was their mission to create a lyophilized single-use Ebola treatment, and in partnership with the team at Ridgeback, that vision became a reality. We would also like to thank FDA leadership and the Ebanga review team at FDA’s Division of Antivirals (DAV) for their focused and thorough review of this product. Finally, the true heroes are the patients and their families who allowed themselves to be carried away from their homes – not knowing if they would ever return – in order to enroll in a randomized controlled trial at the Ebola treatment centers during the 2018-2020 Ebola outbreak in the DRC. Your trust and belief in science, innovation and the people caring for you has transformed Ebola forever. Thanks to you, Ebola is now a treatable disease.”

KYAN Therapeutics Exclusively Enters License Agreement with Georgetown University for AI-Powered Cancer Drug Development

KYAN Therapeutics | September 24, 2020

KYAN Therapeutics, Inc. ("KYAN"), a frontier biotech company with a novel drug-dose combination optimizing platform, Optim.AI, has entered into an exclusive license agreement with Georgetown University for novel selective Class II HDAC inhibitors. KYAN has already commenced preclinical development of the lead candidate, which has been designated as KYAN-001, with early positive results. In vitro and in vivo studies of KYAN-001 have shown high efficacy for Multiple Myeloma and Prostate Cancer. The low toxicity and metabolic stability of KYAN-001 indicates a better safety and tolerability profile than FDA approved pan-HDAC inhibitors which suffer from toxicity issues and side effects. KYAN-001 also uniquely inhibits HDAC4 nucleoshuttling to further drive its anti-cancer effects. "We're very excited to proceed with KYAN-001 because of its promising features and we are confident that we can identify optimal combination therapies across multiple cancer indications with Optim.AI," said Lisa Chow, COO and General Counsel of KYAN.
