U.S. Department of Defense awards 糖心Vlog传媒 Little Rock $5.6 million grant to develop bone regeneration technology /news-archive/2019/10/24/bone-regeneration-dod-grant/ Thu, 24 Oct 2019 14:52:39 +0000 /news/?p=75524 ... U.S. Department of Defense awards 糖心Vlog传媒 Little Rock $5.6 million grant to develop bone regeneration technology]]> The U.S. Department of Defense (DOD) has awarded the University of Arkansas at Little Rock a $5.6 million grant to advance the NuCress鈩 scaffold, a groundbreaking bone regeneration technology.

The grant brings together an interdisciplinary team from 糖心Vlog传媒 Little Rock, led by principal investigator Dr. Alex Biris; the University of Tennessee, Knoxville, led by Dr. David Anderson; and the University of Arkansas for Medical Sciences (糖心Vlog传媒MS), led by Dr. Mark Smeltzer.

Biris and Anderson have worked together since 2006 to develop this pioneering medical device. The NuCress鈩 scaffold is in the final stages of moving from the laboratory to the surgical theater, with potential future uses in both military and civilian hospitals. The new award from the DOD鈥檚 Joint Warfighter Medical Research Program will help facilitate this transition by funding critical go-to-market research.

U.S. Sen. John Boozman, who supported the 糖心Vlog传媒 Little Rock proposal to the DOD and was instrumental in securing federal funding for the project鈥檚 earlier research, congratulated the team on the award.

鈥淏one regeneration technology is so important to the recovery of our warfighters from severe injuries,鈥 Boozman said. 鈥溙切腣log传媒 Little Rock and its partners have made tremendous progress taking this novel nanotechnology solution from the laboratory to the point of clinical trials.鈥

The NuCress鈩 scaffold is an implantable device that promotes controlled, robust bone regeneration in fractures, gaps where bone is missing, and major injury defects, including previously untreatable catastrophic injuries. The device degrades as the bone regenerates, potentially eliminating the need for multiple surgeries-a major source of complications in current bone gap treatments.

鈥淚’m thrilled to see over a decade of collaborative work result in this continued DOD support, and I look forward to seeing it develop into a clinically beneficial product,鈥 said Biris, director of the 糖心Vlog传媒 Little Rock Center for Integrative Nanotechnology Sciences.

Such a device is in high demand by a wide variety of people, including wounded soldiers, victims of major accidents and trauma, and patients with bone disease.

鈥淭he NuCress鈩 scaffold is a game-changing technology that will revolutionize treatment of bone diseases because it is capable of simultaneously promoting bone regeneration and delivering antibiotics, growth factors, and cell-based therapies,鈥 Anderson said.

糖心Vlog传媒 Little Rock Chancellor Christina Drale said the grant will help the Center for Integrative Nanotechnology Sciences fulfill its mission to accelerate world-class innovations in nanotechnology into practical applications that will benefit society.

鈥淭his new funding from the Department of Defense will help our research team fulfill that mission in this particularly exciting area of nanotechnology for medical applications,鈥 Drale said.

Studies funded by past DOD awards proved the scaffold鈥檚 versatility and ability to regenerate large, missing segments of bone. The new, four-year DOD award will support pre-market work, including manufacturing and U.S. Food and Drug Administration clearance. If successful, the project will allow the scaffold to move toward clinical trials, validate its utility for clinicians, and develop a new market application for treating infection.

Smeltzer, the research team鈥檚 infection expert, looks forward to this new market potential.

鈥淚nfection is a dreaded complication of traumatic bone injury, and the ability to incorporate antibiotics into the NuCress鈩 scaffold offers the tremendous added benefit of preventing infection in a contaminated bone defect without compromising its bone regenerative properties,鈥 Smeltzer said.

Nanomaterial bone regeneration technology has wide-ranging benefits /news-archive/2017/03/06/nanomaterial-bone-regeneration-technology-university-arkansas-little-rock/ Mon, 06 Mar 2017 17:52:06 +0000 /news/?p=66502 ... Nanomaterial bone regeneration technology has wide-ranging benefits]]> Dr. Alexandru Biris, director of the 糖心Vlog传媒 Little Rock Center for Integrative Nanotechnology Sciences, led the development of this technology, the NuCress scaffold, a temporary, implantable filler for missing bone that encourages healthy bone regeneration and is absorbed into the body. In addition to its unique 3-D structure, the device can be loaded with beneficial drugs, such as antibiotics to fight infection or hormones and stem cells to encourage healing. Biris began developing the device in 2005, initially intending it for regeneration of small sections of bone, such as in the human jaw. He believes the NuCress scaffold will, one day, be an invaluable tool for repairing the kind of irregular, complicated bone gaps often seen in victims of severe trauma from wartime violence, car accidents, and bone disease. For now, the scaffold is making a name for itself in America鈥檚 heartland. More than a decade ago, Biris started collaborating with Dr. David Anderson, a veterinarian, and the pair have been refining and developing the device ever since.
Dr. David Anderson

Dr. David Anderson

Anderson has conducted biomaterials and bone trauma research since 1991 through his work at Kansas State and Ohio State universities. Since 2012, he has been a professor and the head of Large Animal Clinical Sciences at the University of Tennessee College of Veterinary Medicine. Anderson is an internationally renowned expert in veterinary orthopedic surgery, having given keynote addresses in more than a dozen countries and published extensively on the subject. Anderson鈥檚 position and reputation mean he is occasionally called on to take his skills from the classroom to the community. 鈥淰eterinary teaching hospitals exist for two main purposes. One is to educate vet students, and the other is to serve the community with advanced expertise in technologies,鈥 Anderson said. 鈥淚f the primary veterinarian is not able to fix the problem, they can send it to the tertiary care center at the veterinary teaching hospital, where the equipment and expertise is available to be able to deal with these types of complex problems.鈥 This is exactly what happened in 2010, when he was contacted by a local veterinarian whose patient, a young bull in Kansas, had a serious leg injury likely caused by a misplaced step in a hole. While Anderson and his team were no strangers to complicated animal injuries, this case was unique. 鈥淚t was an open fracture that was very badly contaminated with hair, dirt, manure, and debris. The bone was severely damaged,鈥 Anderson said. Not only was the injury severe, but the stakes were high 鈥 the animal was no ordinary bovine. 鈥淭he bull was an Angus breeding bull selected to add genetic advancement for that herd. This was probably about a $20,000 bull. It would have been a total loss for the owner if the bull was put down.鈥 Initially, Anderson and his team put in an external skeletal fixation system to stabilize the bone, hoping this would be sufficient to heal the bull. The bull, however, was not responding. The complexity and contamination of the wound resulted in a bone break that simply wouldn鈥檛 heal. Infection had set in, conventional methods had been exhausted, and the prize bull was running out of options. 鈥淲e either had to do something dramatic or we would have to euthanize the animal,鈥 Anderson said. Not ready to give up, Anderson turned to his research with Biris. In previous studies, the pair had already shown that their scaffold was effective for delivery of antibiotics. Though this scaffold was smaller in size than what the bull would require, Anderson decided to take a chance. 鈥淚 called Alex 鈥 and I asked if he could make one for this bull to see if we could try to control the infection and stimulate the bone to heal more quickly,鈥 Anderson said. Biris immediately went to work, scaling up the scaffold by almost six times the original prototype鈥檚 size. The scaffold was loaded with antibiotics and implanted by Anderson鈥檚 team inside the bull鈥檚 fractured leg. Then they waited, keeping their expectations low. 鈥淲hen the infection has progressed to that extent, it is actually fairly uncommon to be able to reverse it, and most of these animals with such infections end up being euthanized because they are simply too big to survive with an amputated limb,鈥 Anderson explained. But the bull 鈥 and the scaffold 鈥 defied expectations. Not only did the bone heal, but the infection was stopped in its tracks and completely reversed. These results, Anderson asserts, were astounding. The bull returned to full function in his herd in a relatively short amount of time at a fraction of the cost to the rancher that replacement would have involved. While this experience was not the first evidence of the scaffold鈥檚 usefulness, it reinforced its potential value. 鈥淭here is no question that this is a product that has real merit,鈥 Anderson said. 鈥淚t can change the way we do therapy and can really improve outcomes for patients.鈥 Today, 糖心Vlog传媒 Little Rock has patented the scaffold technology, and Biris, Anderson and their team received about $6听million from the U.S. Department of Defense to develop it further. The researchers hope to bring the NuCress scaffold to clinical trial in the next few years, but they鈥檒l always remember their first successful patient 鈥 a prize bull from a ranch in the heartland.
