On 02.11.2023, the event took place for the second time OrthoRetreat took place at the NIFE under the title "Orthopedic Implants and Surfaces". Research approaches relating to osteoarthritis, the reconstruction of tendons and ligaments as well as patient-specific therapeutic approaches were presented and discussed. The exchange between basic science-oriented researchers with a view to cellular reactions and their pathological correlations and clinicians who face the challenges of individual patients on a daily basis was particularly valuable. This revealed new therapeutic approaches that are producing promising results in initial studies, but whose principles are not yet fully understood and need to be researched in greater depth. The medical and biomedical engineering students in attendance were also able to gain an insight into how clinical issues are viewed from different perspectives and how possible solutions are jointly developed. This valuable exchange was deepened during networking over finger food and drinks and further specific challenges were discussed and new ideas developed together.
On Thursday, October 12, 2023, this year's kick-off event of the TRAIN Academy took place at NIFE. A total of 19 scientists from the Hannover-Braunschweig-Göttingen region will take part in the extra-occupational training "Translational Research and Medicine: From Idea to Product" of the Translational Alliance in Lower Saxony over the next 24 months. Within the scope of the further education, you will expand your knowledge around biomedical product development.
The kick-off event also saw off the graduates of previous years who completed the program. Seven of them were present in person and were able to receive their graduation certificates.
This year, the key note lecture of the kick-off event was held by Prof. Josef Penninger, new Scientific Director of the Helmholtz Centre for Infection Research in Braunschweig since July 2023. The afternoon at NIFE was rounded off with a get-together of the approximately 50 attendees.
From November 6 to 8, the "International Conference on Biomedical Technology" will take place in Hannover. More information is available here.
On Sept. 16, 2023, Prof. Dominik Egger from the Institute of Cell Biology and Biophysics at Leibniz Universität Hannover gave an exciting lecture on the topic of innovative cell culture techniques.

On 11.09.23 - despite high summer temperatures - the 2nd event of the Digital Implant Innovation Forum, which is under the auspices of the Digital Health City Hannover and the NIFE, attracted more than 100 interested people to the NIFE.
The DIIF Forum is dedicated to promoting expert:ing exchange and innovation in the field of smart and precision implants and digitalization in medicine.
The 2nd event, "Next Generation Individualized Patient Solutions by Additive Manufacturing," was all about 3D printing as an ideal platform for personalized implant design such as customization to individual patient anatomy.
The audience was treated to exciting technical presentations ranging from high-performance materials for additive manufacturing to biocompatibility of 3D printed constructs and the use and limitations of AI.
In the afternoon, the Translational Center for Precision Medicine was presented in the presence of Frank Doods, State Secretary of the Lower Saxony Ministry of Economics, Transport, Building and Digitalization, Prof. Michael Manns, President of the MHH, and Prof. Holger Blume, Vice President of the LUH.
The planned translational center is a unique project in Germany that Hannover Medical School is planning together with the NIFE research center and medical technology companies. A translational hub will comprehensively connect the clinics with basic research and the production of implants, so that patients can be supplied individually, quickly and with novel implants from the 3D printer.
An estimated 1 million people in Germany alone receive an implant every year, and demand is rising in the wake of demographic change. By personalizing implants, their so-called "service life" (i.e. functional life in the patent) can be extended and even rehabilitation times shortened. This is made possible by the rapid advances in the field of biomaterials and additive manufacturing.
In summary, the 2nd event of the Digital Implant Innovation Forum (DIIF) lecture series was also a great success and facilitated an excellent exchange between experts from different disciplines. The diverse discussions and presentations have opened up new perspectives. We would like to thank all participants, speakers and organizers for their contribution to this successful event. We are already looking forward to the next DIIF Symposium, which is expected to take place in December 2023 at NIFE and will provide a new opportunity to exchange knowledge and ideas.
# 1 Sensor technology for medicine and implants of tomorrow
On June 21, 2023, the kick-off event of the Digital Implant Innovation Forum under the auspices of the Digital Health City Hannover took place at NIFE.
The forum, which is dedicated to promoting the exchange of experts and innovations in the field of intelligent implants and digitalization in medicine, attracted around 100 experts to the NIFE despite the summer temperatures.
The event started with inspiring greetings from Prof. Windhagen, Executive Board NIFE, who warmly welcomed the participants and particularly emphasized the importance of sensor technology for the further development of implants and medical applications. This was followed by Prof. Bengel as Dean of Research at MHH, who emphasized the importance of the NIFE research center as a focal point of the Medical School. Mrs. Petersen from hannoverimpuls rounded off the greetings by showing how hannoverimpuls makes targeted economic development possible through clever promotion and support.
This was followed by a series of lectures and a discussion in which the experts presented their latest findings and experiences in the field of intelligent implants. They also discussed the often rocky road from the idea to practical application and the associated challenges. The speakers emphasized that innovation in this field not only requires technological know-how, but also has to take into account regulatory aspects, ethics and data protection.
Also discussed were the benefits of digital health applications, such as remote monitoring of implants, personalized medicine and improved patient care. At the same time, however, the associated challenges such as data security and privacy were also highlighted.
In summary, the launch event was a great success. It provided a platform for the exchange of knowledge, ideas and experiences. The interdisciplinary character of the forum enabled a holistic view of this exciting topic and promoted the dialog between experts from different disciplines.
We are already looking forward to the follow-up event, which will also take place at NIFE on 11.09.2023. You will find more information about it on our site soon.
On June 14 and 15, 2023, the first event organized by the German Society for Implant Research and Development (DGIFE) took place at the NIFE. Doctoral students from NIFE in the early phase of their scientific work were invited. The lecturers Prof. Claudia Neunaber, PD. Dr. Janin Reifenrath and Dr. Henning Voigt worked with the participants on the basics of scientific work, experimental design and publication of results. The interactive character of the event was rated particularly positively by the participants.
On 30.06.2023 the 2nd Science Day of the Department of Trauma Surgery took place at NIFE. The research day was a great opportunity to exchange information about the latest developments and advances in trauma surgery.The different working groups of UCH presented their latest research results and findings to their colleagues.The research day helped to further strengthen our knowledge and skills and to promote collaboration between the different areas of trauma surgery.

Samuel John, CEO at OtoJig GmbH opened the event with a presentation on the role of artificial intelligence as a tool for everyday life, science and medicine.
John presented examples of how AI can be used in medical imaging. By using algorithms based on machine learning, physicians and researchers can gain valuable information and make informed decisions. In hearing research, he said, this could help in the treatment of patients, particularly by improving minimally invasive surgical techniques for cochlear implantation. In addition, AI could also play an important role in the development and improvement of medical devices, such as hearing aids.
Next, Prof. Dr.-Ing. Waldo Nogueira presented his research findings on the application of AI to speech understanding in noisy environments for cochlear implant users. He explained that conventional cochlear implants have difficulty understanding speech effectively in environments with a lot of background noise.
He notes that AI algorithms could offer a promising solution to overcome these problems. By using neural networks, AI can analyze background noise and better separate the speaker's speech from background noise. This would allow cochlear implant wearers to better understand speech and participate in conversations even in noisy environments.
Both presentations offered an insightful look at advances in the field. Both Samuel John and Prof. Nogueira showed how AI can contribute to improvement in medical research.
The congress began with greetings from the 1st Chairman of ISPO Deutschland e.V., Michael Schäfer, who warmly welcomed the participants and gave a brief overview of the coming days. In the following days, numerous lectures were held by renowned scientists and researchers who presented their research results and experiences on the topic of amputation and prosthesis care.
Special highlights were the lectures by PD Dr. Alexander Gardetto from Italy on the "Feeling Prosthesis" and the Key Note Lecture in the evening by Prof. Rickard Branemark on Bionic Reconstruction Concepts in the historic Old Town Hall of Hannover. The crowning finale of the scientific congress program was provided by the cooperation partners of trauma surgery from Boston: Corey L. Sullivan (Brigham Hospital, Harvard Medical School) and Michael Fernandez (MIT) impressed the auditorium with their lecture on "Reinventing Amputations". The subject was the "AMI technique" , which was developed by Prof. Hugh Herr (MIT) and Prof. Matthew Carty and which is currently offered in Europe exclusively at the MHH.
The presentations were accompanied by lively discussions and a lively exchange between the participants.
On Friday, in addition to the lectures, there was also a series of workshops where participants could learn practical skills. The workshops were very popular and offered participants a valuable opportunity to expand their knowledge and skills "hands-on".
Overall, the ISPO Annual Congress was a great success. Participants were enthusiastic about the content presented and the opportunities for exchange and networking. The congress once again underscored the importance of amputation and prosthetic care to medical practice and patient care, and inspired participants to continue to work enthusiastically to improve amputation and prosthetic care.

People born deaf use parts of the auditory brain area for vision. However, this does not hinder the recovery of the sense of hearing, MHH researchers found.
Humans have five senses to perceive their surroundings: Sight, hearing, touch, smell and taste. If a person loses one of these, the remaining senses partially compensate for the loss. People born deaf then have enhanced visual abilities. "Crossmodal plasticity" is what science calls the brain's ability to turn to another sensory system when one is lost. Until now, the textbook view has been that a takeover of the auditory system occurs in deafness, with the visual system, for example, irrevocably taking over parts of the auditory cortex. To avoid promoting this effect, some researchers have suggested avoiding communication through gestures or signing with children born deaf before the insertion of a hearing prosthesis such as the cochlear implant (CI).
Now, a German-American team of authors with Professor Dr. Andrej Kral, Scientific Director of the Institute for Audio and Neurotechnology (VIANNA) at Hannover Medical School (MHH), has compared recent data and studies from their own laboratories with others. These data show that crossmodal reorganization changes little in the anatomy of circuits in the brain. The existing networks are just used differently. When hearing is restored, the crossmodal reorganization regresses. The results are published in the journal Trends in Neurosciences been published.
During hearing, sound is converted into electrical impulses in the inner ear and transmitted via the auditory nerve through the midbrain and diencephalon to the cerebral cortex. This is where the auditory cortex is located, which is responsible for processing acoustic stimuli. Deaf people use parts of the auditory processing center in the cerebral cortex for visual impressions, such as motion detection. "Reorganizing the brain is helpful for deaf people to better navigate the environment without an auditory sense," says Professor Kral. "But contrary to earlier assumptions, the neural connections to the auditory sense are not destroyed, so the auditory cortex does not become a battleground between the remaining senses. The existing network is slightly altered and used differently."
This is shown by recent data from animal models as well as from deaf children with hearing loss. Rather, crossmodal reorganization is a dynamic process that makes greater use of already existing nerve connections to other sensory systems, takes place even with mild hearing loss, and regresses after hearing is restored, he says. "Therefore, there is no reason to stop visual communication before inserting a hearing prosthesis," the scientist emphasizes. "This is important for the child's development."
Nevertheless, rapid insertion of a CI is critical in children born deaf. Hearing loss has extensive negative effects on the auditory system itself that cross-modal reorganization cannot compensate for. "Early therapy with a CI is necessary because in congenital deafness, the hearing system itself cannot develop normally," Professor Kral explains. "If a child misses out on early hearing experiences, he or she loses many contact points in the auditory cortex and later fails to learn to recognize auditory impressions and speech sounds and to integrate hearing with other sensory perceptions." Therefore, he said, a hearing prosthesis must be inserted as early as possible, preferably in the first year of life, and at the very latest by age three. "After that, the critical period for hearing therapy is closed."

On 27.05.2023 28 children participated in the Girl`s and Boy`s Day at NIFE. The day was a great success! The children had the opportunity to work with our scientists and experience research first hand.
The students were able to gain an insight into everyday life and the workings of research in the laboratory.
The children learned many important tools and techniques themselves, tried their hand at pipetting, worked with cell cultures and evaluated samples under the microscope. With a lot of enthusiasm, the children have visited different work groups and learned about a wide variety of implants. In the laboratory, the students learned how to cryopreserve cells and examine biofilms.
Some students were also allowed to conduct listening tests at different sound frequencies in an anechoic chamber, a special laboratory room for acoustics experiments where almost no sound is reflected.
The children showed great interest in our research projects and asked many smart questions. We hope that they were inspired by this day and may even have the desire to work in research themselves one day, We look forward to the next generation of researchers and developers.
On 14.03.23 the kick-off event for the new lecture series "Safe implants for the future" of the Transregio Collaborative Research Center SIIRI took place at NIFE.

Ministry of Agriculture honors Professor Dr. André Bleich in the category "Alternative Methods to Animal Testing".
Replacing, reducing or completely avoiding animal experiments in research and improving the conditions for laboratory animals - this characterizes the work of Professor Dr. André Bleich, Director of the Institute for Laboratory Animal Science and the Central Animal Laboratory of the Hannover Medical School (MHH). On Monday, the scientist was awarded the "Lower Saxony Animal Welfare Prize" in the category "Alternative Methods to Animal Experiments" for the research network "R2N - Replace and Reduce from Lower Saxony", which he heads. The prize, worth 6,000 euros, was awarded for the first time by the Lower Saxony Ministry of Food, Agriculture and Consumer Protection. The state representative for animal protection in Lower Saxony, Michaela Dämmrich presented the award. The "Doctors Against Animal Experiments" association also received an award.
With the "Lower Saxony Animal Protection Award", the ministry wants to honor people and organizations that are particularly committed to the protection of animals in the state. The decision had been made by a jury of six experts. "I am very happy that we can honor the commitment to animals as sensitive fellow creatures in Lower Saxony in this way. Last but not least, I hope that we will also use the award to promote the network and exchange of experts and active people in animal protection," says Michaela Dämmrich. The R2N consortium, which was launched in 2017, includes 15 working groups from seven institutions in Lower Saxony. The aim of the project is to develop and apply non-animal methods, especially in basic research.
"Particularly in basic research, the number of animal experiments has been constant for years, while in other research areas they are declining," explains Professor Bleich. However, interdisciplinary collaboration has already enabled various alternative models to be developed for use in biomedical research. "These systems have also already been used, for example in COVID-19 research," says the scientist. The success of the research alliance is also reflected in the scientific journals. More than 50 publications have been published there since the R2N consortium was established.
Informationhow research is currently working to reduce, improve or completely replace animal testing, can be found on the website https://www.3r-forschung.de/.

There were exciting lectures, interesting panel discussions, workshops, and exhibitions. The day vividly demonstrated the diverse research areas at NIFE and gave employees insightful insights.
It is planned to continue the Research Day in the coming years in order to further strengthen the visibility of the different disciplines and to promote interdisciplinary contacts.
On 25.08.2022 Prof. Spranger gave a lecture on "The enigma of ethics committees" for students of biochemistry and for NIFE staff. He brought in many illustrative examples from his own experience. Afterwards, this topic, which has become increasingly complex in recent years and therefore very burdensome for scientists, was discussed with great enthusiasm ("Top 10 of the "all-time classics"). The lecture was held as part of the event series "Development of Cell Therapeutics: Experimental Applications and Clinical Use of Adult Stem Cells", organized by Prof. Dr. Andrea Hoffmann.
Prof. Spranger (Prof.Spranger) is a jurist, lawyer and head of a center for the regulation of modern life sciences. At the Rheinische Friedrich-Wilhelms University in Bonn, he teaches public law and the law of biotechnology, and at the University of Düsseldorf he teaches medical law. As a lawyer, he advises companies, regulatory authorities, research institutions and associations in particular on the evaluation of the latest technical developments.
Prof. Dr. Boris Chichkov from the Institute of Quantum Optics was awarded an ERC Advanced Grant. He is a scientist and member of the Cluster of Excellence QuantumFrontiers and also a member of the Cluster of Excellence PhoenixD.
The ERC Advanced Grant funding line of the European Research Council (ERC) is aimed at established scientists with a longstanding outstanding scientific curriculum vitae who wish to open up new fields of research.
Prof. Dr. Boris Chichkov conducts research on laser biofabrication of 3D multicellular tissue with vascular network (Laser Tissue Perfuse).
Fabrication of three-dimensional vascularised organs is one of the most significant unsolved challenges in the field of biofabrication and tissue engineering. Blood vessels enable the transport of gas, nutrients and metabolites to and from cells and are therefore a basic requirement for the survival of biological tissue - both in vitro and in vivo - following transplantation. In order to reproduce the complexity and structure of functional circulatory systems (arteries and veins, as well as micrometre-sized arterioles, venules and capillaries), new procedures need to be developed for high-resolution, multi-level biological constructs. Research into new approaches involving laser-based bioprinters and two-photon polymerisation is being conducted to achieve this. This unique combination of methods is expected to enable the production of complex vascular networks for the first time.
